Problems solved by technology

However, in the actual operation process, it is found that although the heat pipe can quickly transfer a large amount of heat to the fins for heat dissipation, the temperature of the heat conduction seat at the hot end is still high, and the cooling speed of the heat conduction seat at the hot end is slow, resulting in low heat dissipation efficiency. Poor, which in turn causes the cooling capacity of the semiconductor cooling chip to decrease due to poor heat dissipation, and the overall energy consumption of the refrigeration equipment increases
