[0028] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] like Figures 1 to 3As shown, the heat pipe radiator performance automatic testing equipment 100 of the present application comprises a soundproof box 1, a mechanical arm 2, a heater 3, a refrigeration device 4, a noise receiver 5, temperature sensors and a testing module. The soundproof box 1 isolates the heat pipe radiator 200 from the outside during testing. The mechanical arm 2 is arranged in the soundproof box 1 to hold and fix the heat pipe radiator 200. The heater 3 is arranged on the mechanical arm 2 to heat one end of the heat pipe radiator 200. The refrigeration device 4 is arranged on the mechanical arm 2 to cool the other end of the heat pipe radiator 200. The heating of the heater 3 and the refrigeration of the refrigeration device 4 cause the working medium inside the heat pipe radiator 200 to change from gas to liquid, thereby achieving efficient heat transfer. If there is too much water injection during the gas-liquid change, it will impact the heat pipe radiator 200, thereby causing abnormal noise of the heat pipe radiator 200. The noise receiver 5 is arranged in the soundproof box 1 to collect the abnormal noise generated by the heat pipe radiator 200. The noise receiver 5 is a pickup microphone. The temperature sensors are arranged at the heating end and the cooling end of the heat pipe radiator 200 to detect the temperature of the end of the heat pipe radiator 200. The testing module can be arranged in the soundproof box 1 or outside the soundproof box 1. The testing module is electrically connected with the noise receiver 5 and the temperature sensors to collect the temperature of the heating end and the cooling end of the heat pipe radiator 200 and the sound emitted by the heat pipe radiator 200 during the gas-liquid change, and compare the preset temperature judgment value and the sound source loudness value to determine the performance of the heat pipe radiator 200. For example, within a certain temperature difference range, if the collected sound source loudness value is lower than the preset sound source loudness value, the test is passed, and the performance of the heat pipe radiator 200 is qualified. Otherwise, the test is failed.

[0030] As Figure 4As shown, the heat pipe radiator performance automatic test equipment 100 further comprises a positioning jig 6 and a pushing device 7, the positioning jig 6 is used for positioning the heat pipe radiator 200; the output end of the pushing device 7 is connected with the positioning jig 6, so as to drive the positioning jig 6 to move to the mechanical arm 2.

The rotating device 9 is arranged in the sound insulation box 1, and an output end of the rotating device 9 is connected with the mechanical arm 2. The rotating device 9 can be a servo motor. By arranging the rotating device 9, the heat pipe type radiator 200 can be driven to rotate by a certain angle, so that multi-angle test can be performed on the heat pipe type radiator 200, and the accuracy of the test is improved. In addition, by rotating the heat pipe type radiator 200, the working medium in the heat pipe is in a gravity-following state, so that the working medium can return to the evaporation end more quickly, and thus the abnormal sound is more likely to occur. The mechanical arm 2 comprises a first clamping arm 21 and a second clamping arm 22, and the first clamping arm 21 and the second clamping arm 22 can clamp or release the heat pipe type radiator 200.

Similarly, when the second clamping arm 22 clamps the heat pipe type radiator 200, the refrigerating device 4 is in contact with the heat pipe type radiator 200 and can cool the heat pipe type radiator 200. The noise receiver 5 is arranged on the mechanical arm 2 and located on the rack between the first clamping arm 21 and the second clamping arm 22. By arranging the first clamping arm 21 and the second clamping arm 22, the heat pipe type radiator 200 can be clamped and positioned, and the heat generator 3 and the refrigerating device 4 can be arranged at a distance apart, so that the purpose of simulating the working state can be achieved.
