Description

Liquid Cooling Module

technical field

The invention relates to a liquid-cooled heat dissipation module.

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. Generally, there are two commonly used heat dissipation methods: air cooling system and water cooling system. Among them, the air-cooled system uses a heat sink to straddle the heat source required for heat dissipation, conducts the heat generated by the heat source to the heat dissipation fins of the heat sink, and then generates cold air to blow to the heat sink through a fan. On the cooling fins, the heat is dissipated to the outside world. However, this design method is not only limited by the internal height and weight of the system, but also needs to use a high-speed fan when it is applied to a high-wattage (above 130W) CPU, which may easily cause excessive noise or cause problems. Insufficient thermal capacity.

In addition, in high-end systems, the heat dissipation generated by the central processing unit using direct air blowing alone cannot achieve effective heat dissipation. Another water cooling system must be used to remove 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 (Pump) to circulate the exchange of cold water and hot water. Please refer to FIG. 1, which shows a traditional water-cooling system for a central processor of a high-end system. The bottom surface of a heat-conducting copper base 11 is attached to the surface of a central processing unit 12, so that the central processing unit 12 produces The heat is quickly transferred to the heat-conducting copper seat 11, and the cold water in the water pipe 14 is guided to the S-shaped heat dissipation flow channel in the heat-conducting copper seat 11 through a pump 13, which flows in from the water inlet on the right and flows out from the water outlet on the left. (direction shown by dotted line arrow among the figure), the hot heat produced by this central processing unit 12 is separated rapidly, and the water in the aqueduct 14 becomes hot water because of absorbing the heat that this central processing unit 12 produces at this moment, The pump 13 guides the hot water to the heat pipe 151 of the radiator 15, conducts the heat to the cooling fins 152, and the cold air blown out by a fan 16 dissipates the heat accumulated on the cooling fins to the outside. The hot water in the water guide pipe 14 becomes cold water, and then flows back to the heat-conducting copper seat, so that the heat generated by the central processing unit is continuously circulated and dissipated.

However, in the above-mentioned water-cooling system, due to the large number of connecting pipes, there are problems of poor joint reliability between the water inlet and outlet joints and the water pipes, and the difficulty of water filling and exhausting; moreover, the space and volume occupied by the entire system It is also quite bulky, which does not conform to the increasingly thinner and smaller design trend. Moreover, the required components are numerous and the installation is complicated, thus resulting in a substantial increase in production cost and time.
