PERFORMANCE TESTING DEVICE FOR HEAT PIPE HEATSINK

A performance testing device for heat pipe heatsink is provided according to the present application, including a heating simulation assembly, first temperature sensors and second temperature sensors, the heating simulation assembly is used to simulate heating generation of a heating element and has a heat conduction end face fitted to and transfer heat with the evaporation pipe sections of heat pipes of the heat pipe heatsink; the first temperature sensors are used to detect the temperature of the heat conduction end face, and the first temperature sensors are arranged in one-to-one correspondence with the evaporation pipe sections of the heat pipes; the second temperature sensors are arranged at condensing pipe sections of the heat pipes. In the performance testing device, each heat pipe of the heat pipe heatsink is provided with a corresponding first temperature sensor and a corresponding second temperature sensor, the quality of each heat pipe of the heat pipe heatsink can be judged, which makes the heat dissipation performance test of heat pipe heatsink more accurate, thereby ensuring the heat dissipation performance of the qualified heat pipe heatsink manufactured by the factory, and effectively avoiding the defective heat pipe heatsinks from leaving the factory.
