Description

Technical Field

[0001] The invention relates to the field related to CPU water cooling heads, and in particular to a CPU water cooling head structure which can effectively reduce water resistance. Background Art

[0002] Computer components often generate a lot of heat when working, which will not only cause the computer to work unstably and shorten its service life, but may even damage some components. Therefore, a radiator is usually installed in the computer to absorb this heat. Among them, the CPU, as the core component of the computer, is usually equipped with an independent radiator. There are many types of radiators. At present, CPU radiators mainly adopt air cooling, water cooling and other forms. In addition, a cooling fan is installed in the water-cooled radiator to assist in heat dissipation, which can improve the heat dissipation effect. For the existing water-cooled CPU radiator, the most important thing is the CPU water cooling head that is in direct contact with the CPU.

[0003] A Chinese patent discloses a new type of CPU water cooling head (publication number: CN206757519U), comprising an upper cover, an upper surface of the upper cover is provided with a water inlet and a water outlet, a lower surface of the upper cover is provided with a water inlet and a water outlet, an inner thread groove is provided on the lower surface of the upper cover, a mounting groove is provided on the lower surface of the upper cover, a guide plate is slidably connected inside the mounting groove, the lower surface of the upper cover is slidably connected to the inside of the bracket through an opening, a mounting hole is provided on the upper surface of the bracket, a bottom plate is slidably connected to the lower surface of the bracket, a sealing ring groove is provided on the upper surface of the bottom plate, a sealing ring groove is slidably connected inside the sealing ring groove, a heat dissipation groove is provided on the upper surface of the bottom plate, the CPU water cooling head adopts a two-layer design, uses the upper cover to introduce and outflow water, a water flow channel is arranged inside to facilitate water flow therein, and the bottom plate is used to contact with the CPU and is provided with a heat dissipation groove to facilitate water flow into the heat dissipation groove and take away the heat of the CPU.

[0004] There are several problems with the CPU water cooling head during use:

[0005] The water inlet and outlet of the existing water cooling head are on the same end face, and a guide plate is usually arranged on the heat conducting plate. However, the gap opened by the guide plate is small, so when the water flows through the gap, not only the water flow rate is reduced, but also the water resistance of the water flow is increased. The water flow cannot fully utilize the area of ​​the heat conducting plate, which in turn affects the heat dissipation effect. Moreover, after long-term use, because the water inlet is usually flat and the gaps between the microchannel heat conducting plates are very dense, some impurities and microorganisms in the water flow are easily accumulated on the heat conducting plate, which is cumbersome for users to clean and the cost of replacement is high. Summary of the invention

[0025] Second, when cooling is required, water will enter through the water inlet 2, and then the water will be filtered by the filter plate 6, and will flow along the slope of the water inlet tapered guide groove 54 to the microchannel heat conducting plate 9 for heat conduction, and a part of the water passing through the filter plate 6 will converge at the water inlet convergence guide groove 53, thereby achieving the effect of multi-channel heat dissipation, and making full use of the area where the microchannel heat conducting plate 9 is set, and the water flow that has completed heat conduction will flow out from the water outlet groove 55, and converge in the water outlet convergence guide groove 56, and finally the water will be discharged from the water outlet 3.
