BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a clamping tool for measuring the temperature of a heat pipe, and in particular to a clamping tool for measuring the temperature of a heat pipe by which the temperature measurement of the heat pipe can be rapidly carried out.
2. Description of Prior Art
After heat pipes are completely manufactured, in order to make sure of the quality of the heat pipes manufactured in mass production, each heat pipe should be measured first the capacity of heat transfer to determine whether the expected performance of heat transfer is achieved. However, since the conventional measuring instruments or apparatuses have some problems, such as high in price, complicated in operation and time-consuming in measurement. For example, a thermal couple wire is adhered on the surface of the heat pipe by adhesive tapes. Such a measuring method cannot be applied to all the heat pipes manufactured in mass production, and only some of them can be sampled and measured. After the sampling measurement of the heat pipes manufactured in mass production, the measured results are calculated to determine whether those heat pipes have conformed to the standard, thereby to control the quality of the heat pipes.
However, in order to further improve the quality control of the heat pipes manufactured in mass production, the above sampling measurement is not feasible enough. Therefore, only applying the measurement to each heat pipe and sifting out the bad ones can guarantee the quality of each heat pipe. However, in consideration of the time cost spent in quality control, it is apparent that the existing measuring instruments and apparatuses apparently cannot conform to the rapid and one-by-one measurement.
Therefore, in view of the above the drawbacks, the inventor proposes the present invention to overcome the above problems based on his expert experiences and deliberate researches.
SUMMARY OF THE INVENTION
The present invention is to provide a clamping tool for measuring the temperature of a heat pipe, which can rapidly clamp the heat pipe undergoing the phase change and measure the temperature of each portion of the heat pipe by contacting with the surface of the heat pipe. After rapidly releasing the heat pipe, the temperature measurement is immediately applied to another portion of the heat pipe or to the next heat pipe. Therefore, the time for measuring the temperature of each heat pipe can be greatly reduced to facilitate the one-by-one measurement.
Another, the present invention is to provide a clamping tool for measuring the temperature of a heat pipe, in which a thermal couple wire is used to directly contact with the surface of the heat pipe to achieve a better effect of measuring the temperature.
Accordingly, the present invention provides a clamping tool for measuring the temperature of a heat pipe that comprises a clamping body and a thermal couple wire. The clamping body has a clamping portion constituted by at least two clamping claws. One distal end of the thermal couple wire is formed with a temperature-sensing head. The temperature-sensing head of the thermal couple wire is fixedly provided in the inside of one claw of the clamping body. With the above arrangement, using the clamping body to clamp the portion of the heat pipe whose temperature is to be measurement, and making the temperature-sensing head directly contact with the surface of the heat pipe, the temperature of each portion of the heat pipe can be rapidly obtained. Even, a measured temperature much closer to the actual one can be thus obtained.

DETAILED DESCRIPTION OF THE INVENTION
The detailed description and the technical contents of the present invention will be explained with reference to the accompanying drawings. However, it should be understood that the drawings are illustrative but not used to limit the scope of the present invention.
With reference to Fig. 1, it is a perspective view showing the external appearance of the present invention. The present invention provides a clamping tool for measuring the temperature of the heat pipe, which is used to clamp the surface of the heat pipe 3 undergoing the phase change, as shown in Fig. 2. By contacting with the surface of the heat pipe 3, the temperature of each portion of the heat pipe 3 can be rapidly measured. The clamping tool for measuring the temperature comprises a clamping body 1 and a thermal couple wire 2.
For example, as shown in the present embodiment, the clamping body 1 may further comprise a first clamping handle 10, a second clamping handle 11 and an elastic element 12 provided between the first clamping handle 10 and the second clamping handle 11. The first clamping handle 10 and the second clamping handle 11 faces to each other. Both ends of the first clamping handle 10 are formed with a pressing portion 100 and a claw 101. Similarly, both ends of the second clamping handle 11 are formed with a pressing portion 110 and a claw 111.
Adjacent to the pressing portion 100, 110, each of the first clamping handle 10 and the second clamping handle 11 is provided with a pivoting portion 102,112 mating with each other. A pivot 13 is pivotably connected to the pivoting portions 102 and 112. The elastic element 12 can be a torsion spring provided on the pivot 13. Both ends of the elastic spring abut against the positions inside the first and second clamping handles 10, 11 and adjacent to the pressing portion 100, 110, respectively. The elastic element 12 also can be a compression spring, as shown in Fig. 5, thereby to form the clamping body 1 having elastic claming force. When a user presses the pressing portion 100, 110 of the first and second clamping handle 10, 11 by hands, the claw 101, 111 of the first and second clamping handle 10, 11 will open. After releasing, they close to clamp the heat pipe. According to the above, the clamping body 1 can be provided with a clamping portion 14 having at least two claws 101, 111.
The present invention utilizes the above clamping body 1 to rapidly clamp the heat pipe 3, and in turn measures the temperature of the surface of the heat pipe 3. After rapidly releasing the heat pipe 3, the present invention can immediately measure the temperature of another portion of the same heat pipe 3 or that of the next heat pipe 3. Therefore, in the present invention, one of the claws 101, 102 (e.g., the claw 101 of the first clamping handle 10 in the present embodiment) is provided with the aforementioned thermal couple wire 2. One end of the thermal couple wire 2 is uncovered to form a bare-wire end, and the distal end thereof is formed with a temperature-sensing head 20. By welding the bare-wire end of the thermal couple wire 2, it is melt and a ball-like temperature-sensing head 20 can be naturally formed. The ball-like temperature-sensing head can stably contact with the surface of the heat pipe. The bare-wire end of the thermal couple wire 2 penetrates from the outside of the claw 101 of the first clamping handle 10 into its inside to form the temperature-sensing head 20. The claw 101 can be provided with a through hole 103 for being penetrated by the bare-wire end of the thermal couple wire 2. Further, the inside of the claw 101 is provided with an insulating piece 21, so that the
temperature-sensing head 20 can penetrate through the insulating piece 21 to expose to the outside, as shown in Fig. 3. As a result, the effect of heat insulation can be improved during the heat inductance. Therefore, the temperature measurement of the temperature-sensing head 20 will not be unfavorably affected.
Further, the inside of the claw 111 without the temperature-sensing head 20 (i.e., the claw 111 of the second clamping handle 11 in the present embodiment) is further provided with a soft pad 22 to avoid the surface of the heat pipe 3 from damaging due to the clamping of the first and second clamping handles 101 and 111.
As shown in Figs. 2 and 3, when a number of heat pipes 3 are to be measured, it is only necessary to clamp the portion of each heat pipe 3 whose temperature is to be measured, so that the temperature-sensing head 20 can directly contact with the surface of the heat pipe 3. Owing to the direct contact, the effect of sensing the temperature is excellent. Further, the signals related to the measured temperature are transmitted to the other end of the thermal couple wire 2 connected to a temperature-sensing device (not shown), so that the measured temperature can be displayed or recorded. In this way, the clamping body 1 can rapidly clamp the heat pipe 3 to measure the temperature. After this, the clamping body rapidly releases the heat pipe 3 and then clamps another portion of this heat pipe 3 or the next heat pipe. As a result, the time for measuring the temperature of single heat pipe 3 can be greatly reduced to facilitate the one-by-one measurement.
With the above structure, the clamping tool for measuring the temperature can be achieved.
With reference to Fig. 4, the temperature-sensing head 20 of the thermal couple wire 2 can also be formed previously. Then, the claw 101 of the first clamping handle 10 can be provided with a groove 104 in communication with the through hole 103, so that the bare-wire end of the thermal couple wire 2 can penetrate through the groove 104. Therefore, the thermal couple wire 2 having the previously-formed temperature-sensing head 20 can be still provided on the through
hole 103 of the claw 101,
According to the above, the present invent indeed achieves the desired effects and overcomes the drawbacks of prior art by employing the above structures. Further, the present invention involves the novelty and inventive steps, and conforms to the requirements for a utility model patent.
