BACKGROUND
The background information herein below relates to the present disclosure but is not necessarily prior art.
An automotive cooling system is type of a thermally activated cooling system that works on the principle of sorption cooling. The automotive cooling system consist of a reactor which is basically a tubing assembly. In sorption cooling, a liquid is used as a heating or cooling medium to a catalyst bed which is packed inside the tubes. Since, liquid has a high thermal inertia, utilizing them in sorption cooling reduces the cooling system's COP.
To avoid the above drawback of the high thermal inertia of the liquid, a concentric tube configuration has been proposed. However, maintaining a minimum space between two concentric tubes and maintenance of the concentric tubes are major problem.
There is, therefore, felt a need of a reactor tubing assembly of an automotive cooling system that alleviates the above-mentioned drawbacks.

SUMMARY
The present disclosure envisages a reactor tubing module for a reactor assembly for a thermally activated absorption-based catalytic cooling system. The reactor tubing assembly comprises an inner tube and an outer tube. A catalyst bed is packed inside the inner tube. The outer tube has a diameter larger than the inner tube and is disposed concentric to the inner tube. Thus, an annular space is formed between the inner tube and the outer tube, which provides a passage for a heat exchange fluid to exchange heat with the catalyst bed. At least three spacing elements are disposed in the annular space for maintaining a constant radial separation and concentricity between the outer tube and the inner tube.
Further, the annular space is provided with at least three spacing elements selected from a group consisting a wire, or a dimple or a grooved micro fin or a combination thereof.
In an embodiment, the at least three spacing elements are mounted on operating surface of the inner tube, or the outer tube or a combination thereof.
In another embodiment, each of the spacing element of the at least three spacing elements are disposed perpendicularly to an axis of the reactor tubing module and equiangular with respect to each other.
In another embodiment, the at least three spacing elements are disposed along the length of the reactor tubing module.
In an embodiment, the wire is welded along the length of any one of the inner tube and the outer tube.
Advantageously, the dimples, or grooved micro fins, or thin wires located between the inner and the outer tube reduces the available fluid flow surface area and increases the flow velocity and thus promotes the high heat transfer rate. Also, the configuration offers negligible fluid retention inside the annular space and thus, the minimal thermal inertia.
In addition the dimples or grooved micro fins or thin wires located around the annular space create turbulence in the fluid flow field which results in an increase in the rate of heat transfer.
In a preferred embodiment, the assembly consists of a partitioning plate and a fluid reversal chamber located at two operative ends, collectively configured to provide multi-passes for the fluid flow and thus promotes the rate of heat transfer.
Also, the inner tube is connected to a passage that is selected from a group, consisting of a tubular header, a rectangular header, a square header which improves the performance of the cooling system.
In another embodiment, the assembly is a modular header type arrangement, which results in the reduction of the thermal inertia and mass of the cooling system.
Further, the present disclosure also envisages the reactor assembly for thermally activated absorption-based catalytic cooling system. The assembly comprises a bunch of the reactor tubing modules placed in parallel, a refrigerant collection-distribution header and a tube sheet. Each of the reactor tubing modules comprises the inner tube, the outer tube and the catalyst bed packed inside the inner tube. The diameter of the outer tube is larger than that of the inner tube and disposed concentrically to the inner tube.
Further, the annular space defined between the inner tube and the outer tube provides a passage for a fluid to exchange the heat with the catalyst bed. Also, at least three spacing elements are disposed in the annular space for maintaining constant radial separation and concentricity between the outer tube and the inner tube.
The refrigerant collection-distribution header is being in fluid communication with the inner tubes of the reactor tubing modules. The refrigerant collection-distribution header is configured to collect the desorbed refrigerant as well as to distribute the refrigerant during adsorption. Further, the tube sheet is defining a chamber on each operative end of the bunch of the reactor tubing modules. The chamber is configured to transfer the fluid from an upstream passage to the annular space provided between the outer and the inner tubes.
In an embodiment, the refrigerant collection-distribution header is disposed at each operative end of the bunch of the reactor tubing modules.
In another embodiment, each of the refrigerant collection-distribution headers has a modular construction.

The present disclosure relates to a reactor tubing module 50 for a reactor assembly 500 for thermally activated absorption-based catalytic cooling system. The reactor tubing module 50 comprises an inner tube 450, a catalyst bed 380 packed inside the inner tube 450, an outer tube 480 having diameter larger than the inner tube 450, an annular space 320 defined between the inner tube 450 and the outer tube 480, a plurality of spacing element positioned between the inner tube 450 and the outer tube 480. In an embodiment, at least three spacing elements are disposed between the outer tube 480 and the inner tube 450 in the annular space 320 for maintaining a constant radial separation and concentricity between the outer tube 480 and the inner tube 450.
In another embodiment, the at least three spacing elements are mounted on operating surface of the inner tube 450, or the outer tube 480 or a combination thereof.
In another embodiment, each of the spacing element of the at least three spacing elements are disposed perpendicularly to an axis of the reactor tubing module 50 and equiangular with respect to each other.
The first embodiment of the reactor tubing module 50 of the present disclosure is now explained with reference to figure 1A.
As shown in figure 1A, the cross section of the reactor tubing module 50 consists of the outer tube 480 and the inner tube 450 which are concentrically attached. The outer surface 400 of the inner tube 450 is provided with at least three thin wires 370 as a spacing element between the inner tube 450 and the outer tube 480. The thin wires 370 as the spacing element are welded circumferentially in an equidistant pattern across the length of the inner tube 450. The thin wires 370 are laser welded onto the outer surface 400 of the inner tube 450 so that they are firmly fixed and do not get displaced due to the force of action of flowing fluid. The thin wire 370 can be of shorter length and/or continuous length which extend along the entire length of the reactor tube and helps in maintaining the concentricity of the inner tube 450 and the outer tube 480. Thus, the wire 370 forms an annular space 320 between the inner tube 450 and the outer tube 480.
Further, the annular space 320 formed between the inner tube 450 and the outer tube 480 is configured to allow fluid flow across it. Due to the presence of angularly attached thin wires 370 in the annular space 320, the fluid flow area gets reduced, which results in increase of the fluid velocity inside the annular space 320. Hence, the heat transfer coefficient and the pressure drop increase.
In an embodiment, the annular space 320 provided between the inner tube 450 and the outer tube 480 is less than or equal to 1000 µm. In another embodiment, radial width of the annular space 320 is in the range of 100 to 1000 µm. Also, the diameter of wire 370 used as the spacing element between the concentrically coupled tubes has a diameter of less than 1.0 mm.
In an embodiment, the ratio of radial width of annular space 320 to the radius of said inner tube 450 is in the range of 0.02 to 0.67.
Further, due to the selection of minimum diameter of the thin wire 370, the liquid retention between the annular space 320 is minimized, which results in the reduction of the thermal inertia of the reactor assembly 500. Also, with increase in number of the thin wires 370 inside the annular space 320, the turbulence inside the fluid flow increases, which in-turn increases the rate of heat transfer.
The thin wires 370 are selected from a group, consisting of shape like a cylindrical cross section, a rectangular cross section, and a square cross section etc.
As per another embodiment of the present disclosure, the reactor tubing module 50 for reactor assembly 500 comprises the inner tube 450 packed with the catalyst bed 380, the outer tube 480 having diameter larger than the inner tube 450, the annular space 320 defined between the inner tube 450 and the outer tube 480, a plurality of dimple spacing element 360 positioned between the inner tube 450 and the outer tube 480.
As shown in figure 1B, the cross section of the reactor tubing module 50 consist of the outer tube 480 and the inner tube 450 which are concentrically attached. The inner surface of the outer tube 480 is provided with at least three dimples 360 as the spacing element between the inner tube 450 and the outer tube 480. The dimples 360 as the spacing element are located circumferentially in an equidistant pattern across the length of the outer tube 480.
The dimples 360 provided onto the inner surface of the outer tube 480 forms a mini or micro channels between the inner tube 450 and the outer tube 480. The micro dimples 360 ensure the concentricity of the inner tube 450 and the outer tube 480 across the length of reactor tubing module 50. Also, the micro dimples 360 forms in a helical pattern or in a straight pattern along the length of the outer tube 480. Thus, the micro dimples 360 forms an annular space 320 between the inner tube 450 and the outer tube 480. The height of the micro dimples 360 formed on the inner surface of the outer tube 480 is less than equal to 1.0mm.
Further, the annular space 320 formed between the inner tube 450 and the outer tube 480 is configured to allow fluid flow across it. Due to the presence of angularly spaced micro dimple 360 spacer in the annular space 320, the fluid flow area gets reduced, which results in increase of the fluid velocity inside the annular space 320. Hence, the heat transfer coefficient and pressure drop increase. Also, due to the selection of minimum height of dimple 360 spacers, the liquid retention between the annular space 320 is minimized, which results in the reduction of the thermal inertia of the reactor module 50.
In addition, with increase in number of the micro dimples 360 inside the annular space 320, the turbulence inside the fluid flow increases, this results in breakdown of the boundary layer and additional increase of the rate of heat transfer.
The micro dimples 360 is selected from a group, consisting of shape like a circular cross section, a tear drop cross section, an elliptical cross section, and an almond cross section etc.
As per one more embodiment of the present disclosure, the reactor tubing module 50 for reactor assembly 500 comprises concentrically attached the inner tube 450 and the outer tube 480, the annular space 320 defined between the inner tube 450 and the outer tube 480, a plurality of grooved fins 350 as the spacing element positioned between the inner tube 450 and the outer tube 480.
As shown in figure 1C, the inner surface of the outer tube 480 is provided with at least three grooved micro fins 350 as the spacing element between the inner tube 450 and the outer tube 480. The grooved micro fins 350 as the spacing element are located circumferentially in an equidistant pattern across the length of the inner surface of the outer tube 480.
The grooved micro fins 350 provided onto the inner surface of the outer tube 480 forms a mini or micro channels between the inner tube 450 and the outer tube 480. The grooved micro fins 350 ensure the concentricity of the inner tube 450 and the outer tube 480 across the length of reactor tubing module 50. Also, the grooved micro fins 350 form in a helical pattern or in a straight pattern along the length of the outer tube 480. Thus, the grooved micro fins 350 forms an annular space 320 between the inner tube 450 and the outer tube 480. The height of the grooved micro fins 350 formed on the inner surface of the outer tube 480 is less than equal to 1.0 mm.
Further, the annular space 320 formed between the inner tube 450 and the outer tube 480 is configured to allow fluid flow across it. Due to the presence of angularly spaced grooved micro fins 350 and the spacer in the annular space 320, the fluid flow area gets reduced, which results in increase of the fluid velocity inside the annular space 320. Hence, the heat transfer coefficient and pressure drop increase. Also, due to the selection of minimum height of grooved micro fins 350 spacers, the liquid retention between the annular space 320 is minimized, which results in the reduction of the thermal inertia of the cooling system.
In addition, with increase in number of the grooved micro fins 350 inside the annular space 320, the turbulence inside the fluid flow increases, which results in breakdown of boundary layer resulting in additional increase of the rate of heat transfer.
Furthermore, the grooved micro fins 350 consisting of any shape and width. Also, the numbers of grooved micro fins 350 are varied based on the heat transfer coefficient requirements and allowable pressure drop constraints.
As per another embodiment of the present disclosure, the reactor assembly 500 for thermally activated absorption-based catalytic cooling system comprises a bunch of the reactor tubing modules 50 placed in parallel, a refrigerant collection-distribution header 240 being in fluid communication with the inner tubes 450 of the reactor tubing modules 50, and a tube sheet 300 defining a chamber on each operative end of the bunch of reactor tubing modules 50.
The reactor assembly 500 of the present disclosure is now explained with reference to figure 2 and figure 3.
As shown in figure 2, the refrigerant collection-distribution header 240 is configured to collect the desorbed refrigerant as well as to distribute the refrigerant during adsorption. The refrigerant desorbed from each of the reactor tubing module 50 is collected in a common refrigerant header or manifold 240. Also, the same header or manifold is used as distribution header during adsorption process.
Further, the outer tubes 480 of the reactor assembly 500 are kept stationary by means of tube sheet 300. The tube sheet 300 is configured to transfer the fluid from an upstream passage to the annular space 320 which is provided between the outer tube 480 and the inner tube 450. The tube sheet 300 is joined to the outer tubes 480 by means of a process such as brazing and welding. Also, to increase the fluid flow velocity and heat transfer coefficient, a multi-pass arrangement of fluid is used. The multi-pass arrangement includes a partitioning plate 200 and a fluid reversal chamber 150.
The partitioning plates 200 are located on an inlet-side operative end of the bunch of reactor tubing modules 50. The partitioning plate 200 is configured to divide the bunch of reactor tubing modules 50 into a first section 180 and a second section 160, thereby enabling the flow of heat exchange fluid at the inlet to only one section of the bunch of reactor tubing modules 50, wherein, The fluid reversal chamber 150 is located on the other operative end of the bunch of reactor tubing modules 50. The fluid reversal chamber 150 is configured to enable the flow of heat exchange fluid from the first section 180 to the second section 160 of the bunch of reactor tubing modules 50.
Advantageously, the reactor assembly 500 is provided with a modular header type construction which helps in reducing the thermal inertia and mass of the system. Additionally, the refrigerant collection-distribution header 240 blocks the fluid volume in the fluid headers, which results in the reduction in the fluid volume retention and thermal inertia of the assembly 500.
