Liquid-cooling heat radiator

Abstract

Carrying out heat exchange with heat source, the disclosed liquid cooling type heat sink includes a fan for heat elimination, a pump, a fluid tube, a motor, and a heat elimination block. The motor is in use for driving the fan for heat elimination and the pump. Two ends of fluid tube are connected to the pump to form loop of fluid. The fluid tube is contacted to the heat elimination block, which is setup on the heat source. Being positioned at the path of out air, a curvature of fluid tube is formed on section, where the heat elimination block is left from the fluid tube. The fan for heat elimination cools the said curvature of fluid tube by wind power, increases speed for dropping temperature, and raises efficiency of heat elimination of the fluid tube.

AI Technical Summary

Problems solved by technology

[0004] Since the working fluid flows in the liquid inlet pipe 36a, it is cooled by means of the heat dissipation fan device 20a and the heat exchanger 39a. When the temperature is reduced, the temperature drop time of the working fluid will be reduced, thereby reducing the heat dissipation efficiency

[0005] Furthermore, when the above-mentioned cooling fan unit 20a generates wind force to cool the liquid inlet pipe 36a, the airflow enters and exits along the axial direction of the cooling fan unit 20a, and the motor unit 10a is located at the center of the cooling fan unit 20a, causing the airflow When the radiator fan device 10a enters and exits in the axial direction, it is hindered, so that the maximum air volume and wind pressure are not on the central axis of the motor device 10a but on the outer edge of the fan blade, so that when the radiator fan device 20a acts on the liquid inlet pipe 36a with wind force, Its wind resistance increases and the cooling effect is greatly reduced
