Description

Technical Field

[0002] With the progress of society and the continuous development of science, in many high-tech fields, the constant temperature problem has become one of the common problems that affect the working efficiency of equipment. When the equipment is working, a lot of heat is often generated. As this heat is discharged, the temperature of the working environment of the equipment will rise. As the equipment runs for a long time, the heat in the working environment of the equipment accumulates more and more, resulting in the heat generated by the equipment itself cannot be dissipated in time, which can easily cause the performance of the equipment to decline, and even cause equipment failure. At present, a radiator is usually installed next to the equipment to ensure that the equipment will not overheat and affect the performance. However, the installation of a radiator means an increase in additional energy consumption, and if the heat dissipation flow of the radiator is set too large, it will cause heat dissipation flow redundancy and increase unnecessary energy consumption.
