Description

Water-cooled heat dissipation structure

The invention relates to the field of heat dissipation, in particular to a water-cooled heat dissipation structure.

When a computer is operating, many internal components generate a large amount of thermal energy. Therefore, a good cooling system is a key factor that determines the performance and reliability of the computer. Among all the heat-generating components, the heat dissipation problem of the central processing unit (CPU) and graphics chip processor (GPU) with the highest workload is generally the most difficult. In particular, the screens of various types of computer games are becoming more and more delicate, and the functions of computer-aided graphics software are becoming more and more powerful. Such software often puts the central processing unit and graphics chip processor in a high-load state during operation, and it also causes a large number If the heat energy is not effectively dissipated, it will cause the performance of the central processing unit or graphics chip processor to decline. In severe cases, the central processing unit or graphics chip processor may be damaged or its service life may be greatly reduced.

In order to reduce the operating temperature of heating electronic components, generally, water-cooled devices on the market are connected to a pump (Pump) by a water-cooled drain through two water pipes and a water-cooled head in contact with a heating element (such as a central processing unit). The water-cooled liquid (or working liquid) is driven to the water-cooled row to dissipate heat and continuously circulate cooling to quickly dissipate heat. Please refer to FIG. 1. The conventional water cooling row 1 is composed of a plurality of radiating fins 11, a plurality of flat tubes 12 and two-side water tanks 13. The radiating fins 11 are disposed between the straight flat tubes 12. And the two sides of the two-side water tank 13 and the heat-dissipating fins 11 and the straight strip-shaped flat tubes 12 are welded by solder, so that the two-side water-box 13 and the heat-dissipating fins 11 and the straight bars The flat water pipe 12 is connected to form the water-cooled row 1. The water tank 13 on one side is provided with a water inlet 131 and a water outlet 132. The water inlet 131 and the water outlet 132 are respectively used to connect the opposite two water pipes (not shown in the figure).示).

Because the working fluid flowing from the water inlet 13 is in the water tank 13 on one side, it flows straight through from the straight flat tubes 12 to the water tank 13 on the other side, and then passes through the straight flat tubes. The pipe 12 flows directly through the water tank 13 on the side of the road, and then is discharged from the water outlet 132, so the flow time of the working fluid with heat entering the water cooling row 1 is too short, which relatively makes the working fluid with heat relatively The heat exchange time with the water-cooled row is not long, so that the conventional water-cooled row has a poor heat-dissipating effect on the working liquid with heat, which causes a problem of poor heat dissipation efficiency. In addition, because the overall structure of the conventional water cooling radiator cannot be adjusted according to the space in an electronic device, when it is placed in an electronic device (such as a computer or a server), an independent space is required in the electronic device to provide knowledge. The problem of water-cooled drain placement.
