It has advantages such as good thermal conductivity, simple structure, reliable operation, and uniform temperature. It can be used for heat transfer, heat flux conversion, and thermal control. The application of heat pipe heat exchangers is becoming more and more widespread, and the heat dissipation requirements of heat pipe heat exchangers are also becoming more and more stringent.

[0023] The conveying assembly 2 includes a heating device 21, a rectangular seat 1 23, and a rectangular seat 24. The heating device 21, rectangular seat 1 23, and rectangular seat 24 are fixedly connected to the base plate 1. A gas supply pipe 1 22 is installed between the heating device 21 and the rectangular seat 1 23. A recovery assembly 3 is installed between the heating device 21 and the rectangular seat 24.

The interior of the rectangular seat 1 23 is connected to the sealing assembly 6. Several sets of circular holes 25 are evenly opened on the inner wall of the right end of the rectangular seat 1 23 and the inner wall of the left end of the rectangular seat 24. The circular holes 25 are connected to the heat exchanger 5. The interior of the rectangular seat 24 is connected to the detection assembly 4.

[0024] After installing the corresponding number of heat exchangers 5 by installing the installation component 7, the heating device 21 delivers hot air to the inside of the rectangular seat 23 through the gas delivery pipe 22. Then, the corresponding sealing component 6 is opened, and the hot air flows into the heat exchanger 5 through the round hole 25. Then, the hot air flows into the rectangular seat 24 through another set of round holes 25. After the detection component 4 detects the hot air, the recovery component 3 collects the hot air back into the heating device 21 for continued use.

[0025] The mounting assembly 7 includes two sets of slide rails 71. The two sets of slide rails 71 are fixedly connected to the outer wall of the right end of the rectangular base 23 and the outer wall of the left end of the rectangular base 24, respectively.

[0033] The working principle of the heat exchanger performance precision testing device provided by this utility model is as follows: As needed, several sets of heat exchangers 5 are connected to the conveying assembly 2 through the installation assembly 7. Then, the corresponding sealing assembly 6 is opened, allowing the conveying assembly 2 to transport hot gas into the heat exchanger 5. After the hot gas leaves the heat exchanger 5, the detection assembly 4 detects the hot gas. Finally, the recovery assembly 3 transports the detected hot gas back into the conveying assembly 2 for reuse.

[0034] Compared with related technologies, the heat exchanger performance precision testing device provided by this utility model has the following beneficial effects:

[0035] As needed, several sets of heat exchangers 5 can be inserted into the slide rail 2 71 in sequence through the slider 72 and the limiting plate 73, so that multiple sets of heat exchangers can be tested at the same time, improving the testing efficiency. At the same time, the above device can also quickly remove the tested heat exchangers 5.

[0036] Through the interaction of components such as baffle 62, round hole 25, handle 63 and slide rail 61, the blockage of a specific round hole 25 can be freely released without affecting the leakage of other round holes 25 not connected to heat exchanger 5.
