Then the heating plate 2 is heated to test the performance of the radiator body 3. When the temperature of the heat pipe gradually increases, the contact plate 564 transfers the heat to the heat insulation shell 563, and the temperature is detected in real time by the temperature sensor 565, and the signal is transmitted to the controller 6, and the controller 6 transmits the temperature signal to the display screen 551, so that the heat conduction effect of the heat pipe can be seen in real time.
