Description

Multi-inlet liquid-cooled heat dissipation structure

technical field

The invention relates to the field of heat dissipation, in particular to a liquid-cooled heat dissipation structure with multiple inlets and outlets.

Background technique

At present, liquid cooling devices are widely used in communications, electrical appliances, automobiles, construction and other industries to manufacture various parts and finished products. Taking communications and electrical appliances as an example, when a computer is running, many internal components generate a lot of heat. Therefore, a good cooling system is a key factor in determining the performance and reliability of a computer. Among all the components that generate heat, the heat dissipation problem of the central processing unit (CPU) and graphics chip processing unit (GPU) with the highest workload is generally the most difficult. In particular, the pictures of various 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 also leads to a large number of If the heat energy cannot be effectively dissipated, the performance of the CPU or the graphics chip processor will decrease in light, and in severe cases, the CPU or the graphics chip processor may be damaged or the service life will be greatly reduced.

Please refer to FIG. 1 , in order to reduce the working temperature of the heating electronic components, generally a water-cooled device on the market consists of an existing water-cooling row 1 connected to a water-cooling head of a heating component (such as a central processing unit) through a two-water conduit 51 . 5 and a water pump (Pump) 6, through which the water cooling liquid (or working liquid) is driven to flow to the water cooling row 1 to dissipate heat and continuously circulate and cool, so as to quickly dissipate heat. The existing water-cooling row 1 is composed of a plurality of cooling fins 11, a plurality of flat tubes 12 and two side water tanks 13. The cooling fins 11 are arranged between the straight flat tubes 12, and the aforementioned The two-side water tanks 13 and the cooling fins 11 and the two sides of the straight flat tubes 12 are welded by soldering, so that the two-side water tanks 13 and the cooling fins 11 and These straight flat tubes 12 are connected to form the water cooling row 1, and one water tank 13 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 conduit 51 .

Since the working liquid flowing in from the water inlet 13 flows into the water tank 13 on one side, it quickly flows straight through the straight flat tubes 12 to the water tank 13 on the other side, and then through the straight lines 12 described above The strip-shaped flat tube 12 quickly flows straight through the water tank 13 on the side of the channel, and then is discharged from the water outlet 132, so the flow time of the working liquid with heat entering the water-cooling row 1 is too short, which is relatively hot. The heat exchange time between the working liquid and the water-cooling row is not long, so that the existing water-cooling row has poor antipyretic effect on the working liquid with heat, thereby causing the problem of poor heat dissipation efficiency. In addition, since the overall structure of the existing water-cooling row cannot be adjusted and changed 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 supply the existing Water cooler placement issue.

Therefore, how to solve the above-mentioned existing problems and deficiencies is the direction that the inventor of this case and the relevant manufacturers engaged in this industry are eager to research and improve.
