Description

Water cooling pump structure with check valve and water cooling module

The invention relates to a water-cooled pump structure with a check valve and its water-cooling module, in particular to a water-cooled pump structure with a check valve and its water-cooling module which can prevent the reflux of cooling liquid.

According to the current computer or electronics industry, a large number of processing chips are used, such as central processing units and graphics chips, or other processing chips such as north and south bridges. As the integration density becomes higher and higher, the operation frequency becomes higher and higher. Faster, the heat generated during operation also increases, which is also called heating element. Because these heating elements will cause abnormal operation problems when the operating temperature is too high, and may even burn out. Therefore, in order to effectively reduce the heat, various heat dissipation devices have appeared on the market. It is closely attached to the overflow surface of the heating elements, so as to use conduction, convection or radiation to assist the heat dissipation, so as to keep the heating elements operating at normal operating temperature.

Generally, the most common heat dissipation device is made by various processes using easily conductive metals (such as aluminum or copper). It is composed of a base, a plurality of heat dissipation fins and a heat dissipation fan. The base is used to closely contact the After the heating element, the heat energy is directly conducted to the heat dissipation fins, and the surface of the heat dissipation fins is used to generate heat convection with the outside air, and then the heat energy is dissipated to the outside world, or a heat pipe is combined to enhance the heat dissipation effect. A closed tube is filled with a liquid heat dissipation medium, the main component of the heat dissipation medium is water, and the rest is composed of special components that can increase the heat transfer capacity of the liquid. One end of the heat pipe is the evaporating end and is in contact with the heating element for absorbing the heat so that the heat dissipation medium absorbs heat and then evaporates into a gaseous state, and moves to the condensing end of the other end of the heat pipe to dissipate heat, so that It forms a closed heat dissipation cycle, and the heat dissipation medium can be used to take away a large amount of heat at one time, thereby achieving the purpose of improving heat dissipation efficiency.

In addition, there is also a water-cooled heat dissipation module that simply uses liquid circulation to dissipate heat. It uses a circulating pump to drive a cooling liquid (usually water) that has a large specific heat and can absorb heat. When it flows through the heating element, it can absorb heat at the same time, and The flow of the cooling liquid is used to take the heat away from the heating element, and the heat is discharged between the passing pipelines or in the water storage tank to achieve the purpose of dissipating heat; however, in order to increase the heat dissipation efficiency, some industries will use water cooling to dissipate heat. The module uses the method of stacking pumps up and down to dissipate heat. It collects the cooling liquid in each pump and then flows out through the tube body, so that the cooling liquid is continuously circulated and dissipated. However, this installation method is one of When the pump is destroyed, the internal cooling liquid cannot be driven to flow due to the destruction of the pump. At this time, the internal cooling liquid will cause backflow problems, and the liquid cannot be circulated smoothly, resulting in worse heat dissipation efficiency.
