[0026] See also Figure 1 The utility model discloses a single-channel heat pipe test device, which includes a workbench 1, a heating unit 2 and a DC power supply 3. The heating unit 2 is arranged on the top side of the workbench 1, and the output end of the DC power supply 3 is electrically connected to the input end of the heating unit 2. In practical applications, the radiator to be tested is placed on the top side surface of the workbench 1, and the heating unit 2 moves to the heat pipe to be tested of the radiator to heat the heat pipe; in this process, the DC power supply 3 outputs a stable DC power supply 3 to the heating unit 2, thereby realizing the single-channel thermal efficiency test of the heat pipe by the heat pipe single-channel test device. Traditional heat pipe test equipment usually uses multiple heating units 2 to perform multi-channel tests on multiple heat pipes. However, due to the difference in heat energy output efficiency between different heating units 2, errors exist in the test results of different heat pipes during the multi-channel test, thereby affecting the test accuracy of the test equipment for the heat pipe; compared with traditional heat pipe test equipment, the heat pipe single-channel test equipment of the utility model performs single-channel tests on heat pipes through a single heating unit 2, thereby effectively eliminating system errors and effectively improving the accuracy of the heat pipe thermal effect test results.
[0027] Furthermore, the heat pipe single channel test equipment also includes a mounting frame 4, which is arranged across the top side of the workbench 1. Specifically, the heating unit 2 is installed on the top of the mounting frame 4, and the output end of the heating unit 2 is arranged toward the workbench 1, so that the heating unit 2 can perform a heat pipe single channel thermal efficiency test on the radiator placed on the top of the workbench 1.
[0028] Furthermore, the heating unit 2 includes a driving cylinder 21 and a heating block 22. The driving cylinder 21 is mounted on the top of the mounting frame 4, and the output end of the driving cylinder 21 is arranged toward the workbench 1; the heating block 22 is arranged at the output end of the driving cylinder 21, and the input end of the heating block 22 is electrically connected to the output end of the DC power supply 3. In actual application, the operator places the radiator to be tested on the top of the workbench 1 and sets it on the bottom side of the heating unit 2; the driving cylinder 21 drives the heating block to descend to the surface of the radiator and contact the heat pipe to be tested in the radiator; the DC power supply 3 outputs stable DC power to the heating block, so that the heating block is heated to a preset temperature to heat the heat pipe, and then completes the subsequent test of the thermal efficiency of the heat pipe.

Specifically, the driving cylinder 21 is installed on the mounting plate 42, and the driving cylinder 21 is slidably connected to the mounting plate 42, so that the driving cylinder 21 can reciprocate along the length extension direction of the mounting plate 42. When the radiator is placed on the top side surface of the workbench 1, the operator can slide the driving cylinder 21 along the mounting plate 42 to the top side of the radiator heat pipe, and then drive the heating block to descend through the driving cylinder 21 to heat the heat pipe.
[0031] Furthermore, the mounting plate 42 is arranged parallel to the top side surface of the workbench 1 in the length extension direction, thereby uniformly limiting the setting distance between the heating unit 2 and the surface of the workbench 1. When the heat pipe single-channel test equipment performs a thermal efficiency test on the radiator heat pipe of the same size, the driving cylinder 21 can work at the same output distance, thereby improving the detection efficiency.
