Description

TECHNICAL FIELD

[0001] The utility model relates to radiator technical field, concretely is a water cooling plate type radiator. BACKGROUND

[0002] With the rapid development of modern electronic technology and industrial technology, the performance of various electronic devices and industrial devices is continuously improved, and the power density and heat generation amount in the operation process are also sharply increased. For example, in the field of high-performance computers, the central processing unit (CPU), the graphics processing unit (GPU) and other core components will generate a large amount of heat when performing complex operations. If these heat cannot be effectively dissipated in time, the temperature of the components will be too high. According to the characteristics of electronic components, the high temperature will significantly reduce the working efficiency, cause the electronic migration phenomenon, accelerate the aging of the components, and even cause permanent damage to the components in severe cases, directly affecting the running stability and service life of the computer, so a radiator is needed for heat dissipation.

[0003] The traditional heat dissipation mode, such as air cooling, although simple structure and low cost, but the heat dissipation efficiency is relatively limited, the water cooling radiator can more efficiently take away the heat from the heat source by using the large specific heat capacity and good thermal conductivity of water.

[0004] Chinese utility model patent publication No. CN 210491511 U discloses a plate type water cooling radiator, which can be used for installing various electronic devices. The cooling water flows into the water inlet pipe, flows out from the water outlet pipe after passing through the heat exchange assembly, and takes away the heat during the flow process, thereby achieving the heat dissipation effect. The heat conduction fins are arranged to increase the contact area of the cooling water, thereby greatly improving the heat dissipation effect. However, the plate type water cooling radiator has a relatively complex structure, is inconvenient to assemble, and has a relatively large thickness, which is not conducive to arrangement in a small space.
