Description

Liquid Cooling Module

technical field

The invention relates to a liquid-cooled heat dissipation module, in particular to a liquid-cooled heat dissipation module with a fan and a pump in one.

Background technique

With the ever-changing computer execution efficiency and functional requirements, the processing speed is getting faster and faster. After a period of continuous use, the central processing unit (CPU) or other electronic components used on the computer motherboard will be damaged due to high-frequency oscillation or electromagnetic effects. The phenomenon of temperature rise occurs, if it is not dissipated in time, it will easily lead to damage of electronic components or affect their efficiency. The commonly used heat dissipation method is to use a heat sink to straddle the heat source required for heat dissipation, conduct the heat generated by the heat source to the heat dissipation fins of the heat sink, and then generate cold air through a fan to blow to the heat sink. on the fins, thereby dissipating the heat to the outside world.

However, in high-end systems, it is impossible to achieve effective heat dissipation by using direct air blowing alone to dissipate the heat generated by the CPU during operation. Water cooling must be used to dissipate the heat and use a large area of air to dissipate heat. In order to achieve a better heat dissipation effect. But this heat dissipation method must add an additional pump to circulate the exchange of cold water and hot water. Referring to FIG. 1A, it is a traditional water-cooled heat dissipation system for a central processing unit of a high-end system.

And this moment, the water in the aqueduct 14 becomes hot water because of absorbing the heat produced by the central processing unit 12. The cold air dissipates the heat accumulated on the cooling fins to the outside, at this time, the hot water in the aqueduct becomes cold water, which continues to circulate and dissipate heat continuously.

In addition, the fan 16 and the pump 13 used in the above-mentioned water-cooled heat dissipation system each need a set of motors to drive, and the stator silicon steel sheet 131 of the motor used in the pump and the rotor magnetic ring 132 must be waterproofed and isolated, as shown in the figure 1B. A plastic layer 133 and a safety rotational gap are thus formed between the two. This design not only increases the gap between the stator and the rotor, but also weakens the torque, and the space and volume occupied by the entire system are also quite large, which does not conform to the increasingly thinner and smaller design trend.
