Technical Field

[0001] The utility model relates to a heat dissipation cold plate, in particular to a multi-directional heat dissipation fin high heat flux density heat dissipation cold plate. Background Technique

[0002] One way to apply to the heat dissipation of electronic devices is cold plate cooling. Cold plate cooling is a traditional electronic component thermal management method, mainly through the flow of internal coolant for heat exchange, generally mainly in the form of single-phase heat exchange, and the heat flux density of heat exchange is limited. For the heat exchange enhancement of the cold plate, it is mainly achieved by changing the channel structure and the fluid flow mode, mainly for the research of micro-channel cold plates, which is essentially achieved by increasing the heat exchange area.

[0003] When the existing high heat flux density heat dissipation cold plates are in use, their heat dissipation performance needs to be improved. At the same time, during use, they cannot dissipate heat in multiple directions well, and there are certain deficiencies in heat dissipation performance, which is not conducive to use. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a multi-directional heat dissipation fin high heat flux density heat dissipation cold plate, effectively solving the problems that when the existing high heat flux density heat dissipation cold plates are in use, their heat dissipation performance needs to be improved, and at the same time, during use, they cannot dissipate heat in multiple directions well, and there are certain deficiencies in heat dissipation performance, which is not conducive to use.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: The utility model includes a cold plate body for heat dissipation. Both ends of the cold plate body are respectively installed with a first cover and a second cover through first fixing bolts. It also includes an inlet pipe flange, an outlet pipe flange and a multi-directional heat dissipation component. The multi-directional heat dissipation component is installed on one side of the cold plate body;

[0006] The multi-directional heat dissipation component includes an outer exhaust fan, a first heat dissipation piece and a second heat dissipation piece. The outer exhaust fan is installed in the middle of the outside. Four first heat dissipation pieces are installed around the outer exhaust fan. Second heat dissipation pieces are installed at the four corners around the outer exhaust fan. The first heat dissipation piece is composed of a first heat dissipation plate at the bottom, several transverse heat dissipation fins installed on the surface of the first heat dissipation plate, first installation blocks arranged at the four corners of the first heat dissipation plate, the first installation blocks being fixed to the cold plate body through second fixing bolts and first bolt holes opened at the positions corresponding to the second fixing bolts on the first installation blocks. The second heat dissipation piece is composed of a second heat dissipation plate arranged at the bottom, several oblique heat dissipation fins arranged on the surface of the second heat dissipation plate, second installation blocks arranged at the four corners of the second heat dissipation plate and second bolt holes opened at the positions corresponding to the second fixing bolts on the second installation blocks.

[0007] Preferably, an inlet pipe flange is arranged in the middle of one side of the first cover, and an outlet pipe flange is arranged in the middle of one side of the second cover.

[0008] Preferably, the first heat dissipation plate and the second heat dissipation plate are made of aluminum or copper.

The air moves outward along the inclined heat dissipation fins on the second heat dissipation plate, and the cold plate body can be dissipated in multiple directions. Through the installed transverse heat dissipation fins and inclined heat dissipation fins, the cold plate body is dissipated. The installed external exhaust fan assists the transverse heat dissipation fins and inclined heat dissipation fins to dissipate heat in multiple directions, improving the heat dissipation performance.
