The temperature of a first liquid-cooling radiator is reduced through the conduction of the semiconductor refrigeration chip to reduce the temperature of a CPU.

A first water-cooled pipe and a second water-cooled pipe use a quick disassembly and assembly structure.

TECHNICAL FIELD

The present disclosure relates to the technical field of heat dissipation devices, specifically a dual liquid-cooling radiator for a semiconductor refrigeration system.

BACKGROUND

As the performance of computer systems gradually improves, the heat generated by the operation of electronic components such as CPUs also inevitably increases. In order to solve the heating problem, a heat dissipation system is usually required to quickly dissipate heat, so as to prevent electronic components from being reduced in life or damaged due to overheating.

A high-efficiency water-cooled radiator provided by the utility model with the application number CN219105445U includes a heat-conducting assembly, an air-cooled assembly, and a water-cooled assembly. After the user attaches and installs the heat sink to the electronic components that needs heat dissipation, the heat of the electronic component is conducted to the heat sink. The circulating liquid in the water-cooled assembly enters the water outlet tank, then sprays from the water outlet on the waterway cover plate to the middle of the micro water channel, flows to the surroundings of the micro water channel, then flows from the water inlet on the waterway cover plate into the water inlet tank, and finally flows from the inlet water tank into the water-cooled assembly for heat dissipation to achieve water-cooled heat dissipation of the water electronic component. After the air-cooled fan is started, air enters from the air inlet and blows out from the air outlet. The air blowing from around the air-cooled cover blows away the heat emitted around the electronic component, thus solving the problem of heat dissipation around the electronic component. However, the heat transfer rate of this type of radiator is average, causing the heat dissipation efficiency of the CPU radiator to be unsatisfactory. Therefore, there is an urgent need to design a radiator which can directly and quickly cool the heat sink through the semiconductor refrigeration chip, so that the cooled heat sink can quickly reduce the temperature of the motherboard CPU, and the heat generated by the cooling of the semiconductor refrigeration chip can be reduced for cooling through the second liquid-cooling radiator.
