THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE NATURE OF THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

Field of the Disclosure
The present disclosure relates to a condenser module assembly for passenger and commercial vehicles. In particular, the present disclosure relates to sealing for the condenser module assembly that directs rammed air towards a condenser core for achieving an optimal performance of the condenser module assembly.
Background
In motor vehicles, a condenser core is an important part of the heat exchanger unit. Normally, the condenser core is in the form of a flat core placed behind a front grill for effective cooling by the ambient air ramming thereon.
For a better performance of the condenser module assembly, the condenser core is usually provided with sealing in the form of baffles or diverter plates that direct the straying rammed air towards the condenser core to an optimum effect. An efficient sealing arrangement not only properly directs the ambient air towards the condenser core for an efficient heat exchange, but also restricts hot air flowing in from the engine side towards the condenser, wherein such hot air recirculation may put additional load on the condenser unit. Therefore, by utilizing an efficient arrangement of the sealing, the heat load on the condenser is kept to a minimum. Further, the efficient sealing arrangement also ensures that the rammed air is utilized for most optimum heat exchange effect in the condenser core.

At present, the entire condenser assembly along with condenser core and sealing are required to be dropped down from above the vehicle during its assembly to the vehicle. However, there is a very confined space around the point of entry from top of the vehicle. Therefore, it is quite difficult to locate the condenser along with the sealing assembled to the condenser. So, the sealing is required to be assembled with the condenser core separately, or their size is limited to the extent of space available for insertion of the condenser core from the top of the vehicle.
Objects
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows:
A principle object is to provide a sealing for a condenser core that provides optimum sealing effect of the condenser.
Another object is to provide a foldable sealing for a condenser core that facilitates use of a relatively larger sized sealing.
Still another object is to provide a condenser core assembly that can be easily assembled on a vehicle even in confined spaces.
Yet another object is to provide a condenser core assembly that is foldable to a compact configuration.

Other objects and advantages of the present disclosure will be more apparent from the following description when read in conjunction with the accompanying figures, which are not intended to limit the scope of the present disclosure.

Detailed description of the accompanying drawings:
The sealing for a condenser core in accordance with the present disclosure will now be described with reference to the accompanying drawings which do not limit the scope and ambit of the disclosure. The description provided is purely by way of examples and illustrations.

To overcome the problems associated with the prior art systems, the condenser is configured in such a manner that the sealing is foldable inwards, i.e. flush with the condenser core before the assembly on the vehicle at the designated mounting space.
After the assembly of the condenser along with these inwardly folded sealing (as shown in Figure 6A) the sealing can be opened outwards (as shown in Figure 6B) for obtaining an optimum sealing effect of the condenser. This is possible because once mounted, normally there is slightly more space available around the mounted condenser core.
Such an arrangement of the sealing facilitates use of larger sized foldable sealing, thereby optimally utilizing the sealing for obtaining an optimum sealing effect of the condenser, which is not possible until now. Further, such an arrangement of the sealing facilitates a more effective sealing of the hot air coming in from the engine side.
Once the condenser was fastened on to the vehicle frame, the seals would be opened to their desired position. The foldable configuration of sealing prevents the sealing from getting damaged during the assembly thereof. Further, the foldable arrangement of sealing also has substantial labor costs advantages, because it is quite easy to open folded sealing than to assemble the conventional sealing in the very confined space available.
To achieve the foldable configuration of sealing for the condenser core, the condenser plastic seal frames 5 are designed with hinges and sliders 6 (As

illustrated in Figure 7). These frames are provided with snap fittings 9, which snap fit onto the left hand manifolds 7 and Right hand manifolds 8 of the condenser (As illustrated in Figure 7A).
The sealing for a condenser core in accordance with the present disclosure herein and the various features and advantageous details thereof are explained with reference to the non-limiting embodiments in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein.
The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
The description herein after, of the specific embodiments of sealing for a condenser core will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments.

The condenser core 1 along with the sealing 2, 3 and 4 assembled thereto may be referred to as a condenser core assembly. Figure 1A illustrates a bottom view of the condenser core assembly. The sealing 2 and 4 of the core assembly are adapted to fold with respect to core 1 to configure a folded and an open configuration. Figures 1 - 1D illustrates different views of the condenser core assembly with the sealing 2 and 4 in the open configuration with respect to core 1.

Figure 2 shows a perspective view of the condenser core 1 with the sealing 2, 3 and 4 assembled thereto in accordance with the present disclosure. More specifically, the sealing 2 and 4 are disposed at the opposing sides of the condenser core 1 and a bottom sealing 3 is disposed at the bottom side of the condenser core 1.
Figure 2 illustrates the sealing 2, 3 and 4 of the condenser core assembly in their open configuration after being assembled inside the vehicle. The

condenser core 1 is designed such that the seals 2, 3 and 4 are in closed configuration as illustrated in Figure 6A during the mounting of the condenser core 1 onto the vehicle. Once the condenser is fastened to the vehicle frame, the sealing 2, 3 and 4 are opened by the operator to their desired open configuration as illustrated in Figure 6B. Figure 2A shows another perspective view of the condenser core 1.

The hinge and slide arrangement facilitates folding of the sealing 2, 3 and 4 with respect to the condenser core 1. More specifically, in order to achieve folding of the sealing 2, 3 and 4 with respect to the condenser core 1, plastic seal frames 5 are configured with hinges 6 and sliders. These frames are provided with snap fittings 9, which would snap fit onto the left hand manifold 7 and right hand manifolds 8 of the condenser.
Figure 7A illustrates a detailed view of the arrangement of the hinge and slider 6 shown in Figure 7.
Figure 7B illustrates a detailed view of one of the snap fittings 9 which snap fit onto left and right hand manifolds (marked by 7 in Figure 7).
Figure 8 illustrates an enlarged view of the hinge and slide arrangement of the sealing assembled with the condenser core 1. The sealing 2, 3 and 4 are provided with hinges and slides, which slide on to the plastic frames. The condenser assembly with the sealing would remain in the closed position.
Technical Advantages & Economic Significance
The technical advantages of the sealing arrangement for a heat exchanger device include the following:

The entire condenser assembly including the condenser core and sealing can take up a compact configuration that facilitates assembly of. the condenser core and sealing to the vehicle at appropriate location.
