Liquid cooling heat dissipation surface spraying structure

Abstract

The utility model discloses a liquid cooling heat dissipation surface spraying structure which comprises a liquid cooling cover and a bottom plate. Radiating fins are arranged on the bottom plate; the inner wall of the liquid cooling cover and the surfaces of the cooling fins are coated with heat dissipation layers. The liquid cooling cover is in sealed connection with the bottom plate; and heat dissipation layers are sprayed on the outer walls of the liquid cooling cover and the bottom plate. The liquid cooling cover is installed on the bottom plate, and a liquid cooling space is formed between the liquid cooling cover and the bottom plate. The liquid cooling cover is provided with a water inlet and a water outlet. And a supporting strip is arranged between the liquid cooling cover and the bottom plate. The heat dissipation layer is a polymer composite material layer or a metal powder layer. The heat dissipation layer is a ceramic layer or a graphene layer. The cooling fins are of a structure with the middle higher than the two ends. The liquid cooling head has the technical effects and advantages that the heat dissipation layer is further sprayed outside an original liquid cooling head heat dissipation characteristic structure, and then the heat dissipation performance of the whole vapor chamber is improved. And the appearance selectivity of surface spraying can be increased in appearance instead of pure metal coating appearance color. And the design is more attractive and humanized.

Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, and more specifically to a liquid cooling heat dissipation surface spraying structure. Background Art

[0002] In recent years, the power consumption TDP of CPUs and GPUs has been increasing year by year. Conventional liquid cooling head designs generally use coatings for surface anti-corrosion treatment, making it difficult to further break through in terms of heat dissipation performance. Additionally, the appearance is relatively single and difficult to meet more personalized needs. Content of the Utility Model

[0003] In order to overcome the above defects of the prior art, the utility model provides a liquid cooling heat dissipation surface spraying structure.

[0004] The technical solution of the utility model is as follows:

[0005] The liquid cooling heat dissipation surface spraying structure includes a liquid cooling cover and a bottom plate; heat dissipation fins are provided on the bottom plate; heat dissipation layers are sprayed on the inner wall of the liquid cooling cover and the surface of the heat dissipation fins; the liquid cooling cover is hermetically connected to the bottom plate, and heat dissipation layers are sprayed on the outer walls of the liquid cooling cover and the bottom plate.

[0006] The liquid cooling cover is installed on the bottom plate, and a liquid cooling space is formed between the liquid cooling cover and the bottom plate.

[0007] Water inlets and outlets are provided on the liquid cooling cover.

[0008] Support bars are installed between the liquid cooling cover and the bottom plate.

[0009] The heat dissipation layer is a high molecular composite material layer or a metal powder layer.

[0010] The heat dissipation layer is a ceramic layer or a graphene layer.

[0011] The heat dissipation fins have a structure that is high in the middle and low at both ends.

[0012] The technical effects and advantages of the utility model:

[0013] Outside the original heat dissipation characteristic structure of the liquid cooling head, a heat dissipation layer is further sprayed to improve the overall heat dissipation performance of the heat dissipation plate.

[0014] In terms of appearance, the appearance selectivity of surface spraying can be increased, rather than simply the appearance color of the metal coating. It is more beautiful and humanized in design. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 - 4 shown in the liquid-cooled heat dissipation surface spraying structure, including a liquid-cooled cover 1 and a bottom plate 2; a heat sink 3 is provided on the bottom plate 2; a heat dissipation layer is sprayed on the inner wall of the liquid-cooled cover and the surface of the heat sink; the liquid-cooled cover is hermetically connected to the bottom plate, and a heat dissipation layer is sprayed on the outer walls of the liquid-cooled cover and the bottom plate.

[0021] Furthermore, the liquid-cooled cover is installed on the bottom plate, and a liquid-cooled space is formed between the liquid-cooled cover and the bottom plate.

[0022] Furthermore, a water inlet 11 and a water outlet 12 are provided on the liquid-cooled cover.

[0023] Furthermore, a support bar 4 is installed between the liquid-cooled cover and the bottom plate.

[0024] Furthermore, the heat dissipation layer is a high molecular composite material layer or a metal powder layer.

[0025] Furthermore, the heat dissipation layer is a ceramic layer or a graphene layer.

[0026] Furthermore, the heat sink has a structure that is high in the middle and low at both ends, which is conducive to liquid flow.

[0027] In this design, on the inner and outer surfaces of the water-cooled structure, materials such as ceramics, copper-aluminum metals, cermets, and high molecular composite materials are sprayed by hot melt spraying. In addition to the heat dissipation characteristics of the original liquid cooling itself, the overall heat dissipation performance of the heat pipe is further improved by spraying on the surface.

[0028] For the appearance, the appearance selectivity of surface spraying can be increased, rather than simply the appearance color of the metal coating.

[0029] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
