Problems solved by technology

However, at present, water-cooled radiators are generally sealed by sealing rings or vacuum brazing. During the long-term thermal cycle, the radiator is prone to failure, resulting in water leakage. At the same time, vacuum brazing is likely to cause solder to block the water channel, thereby increasing the flow resistance.

Abstract

The invention discloses a radiator using a double-sided high-efficient water-cooled spiral structure to improve efficiency. The radiator comprises a base plate, a first cover plate and a second coverplate; a circular groove is formed in the surface of the base plate, a water-cooled channel is formed in the bottom of the circular groove, the water-cooled channel is a worm groove, a first flow guiding hole is formed in one end of the water-cooled channel, and a second flow guiding hole is formed in the other end of the water-cooled channel; a first water inlet and a second water inlet are formed in one side surface of the base plate, a channel is formed in the other side surface, wherein the second water inlet is communicated with the second flow guiding hole, and the channel is communicated with the first water inlet and the first flow guiding hole. The invention aims at providing the radiator using the double-sided high-efficient water-cooled spiral structure to improve the efficiency, and heat generated by electronic components can be dissipated efficiently and reliably to ensure the normal operation of the electronic components.

Description

technical field [0001] The invention belongs to the technical field of water-cooled radiators, and in particular relates to a radiator that utilizes a double-sided high-efficiency water-cooled spiral structure to improve efficiency. Background technique [0002] With the rapid development of the electronics industry, the volume and power of electronic components continue to increase, while the volume of electronic products itself continues to decrease, and the volume of radiators increases with the heat dissipation power. high demands. However, at present, water-cooled radiators are generally sealed by sealing rings or vacuum brazing. During the long-term thermal cycle, the radiator is prone to failure, resulting in water leakage. Therefore, it is of great significance to develop efficient, reliable, and smaller water-cooled radiators. Contents of the invention [0003] The purpose of the present invention is to provide a heat sink with double-sided high-efficiency water...
