AI Technical Summary

Problems solved by technology

The traditional heat pipe performance testing equipment only relies on the refrigerator to cool the heat pipe through the cold plate, and each device is equipped with a refrigerator. This configuration has the following problems: First, the cooling speed is slow when the refrigerator is directly used for cooling, and the production efficiency is low. Not high; the second is that when using multiple test equipment, more refrigerators are required. Because the refrigerator needs to generate heat when cooling, the ambient temperature of the test workshop is high and the environment is harsh. Additional air conditioners are needed to maintain the temperature of the test workshop. The third is that the traditional heat pipe performance testing machine only has the cooling method of cold plate + cooling water, and the temperature of the cold plate fluctuates greatly, resulting in poor test consistency; the fourth is that the traditional cooling method has poor cooling effect, and the heat pipe It takes a long time to reach the equilibrium state, so the test time is long; fifth, the traditional heat pipe performance testing machine simply uses the cooling water tank for cooling, the cooling water tank is in the working state for a long time, and the water temperature gradually rises, so the failure rate is high
