Cooling plate and manufacturing method thereof

Abstract

The invention provides a cooling plate and a manufacturing method of the cooling plate. The cooling plate comprises a metal plate and a frame. Closed thermal superconduction pipelines are arranged inthe metal plate and communicate with one another. Each thermal superconduction pipeline is filled with a heat transfer working medium. The metal plate further comprises a refrigerant channel, so thatthe cooling effect of the cooling plate can be improved. The metal plate and the frame are tightly connected through an insert injection molding technology. The frame is divided by the metal plate into at least one containing cavity.

Description

technical field [0001] The invention relates to the field of heat dissipation plates, in particular to a heat dissipation plate and a manufacturing method thereof. Background technique [0002] At present, the materials used for heat exchange in the industry mainly use heat sinks. At present, most heat sinks use single-pipelines, multiple bending fluid passages in order to maximize the heat dissipation area, or use additional cooling fins. Due to the limitation of the thermal conductivity of the material and the volume of the board, these two methods have a large thermal resistance, and the fluid pipeline / radiating fin cannot cover the entire board surface, resulting in uneven temperature on the board surface and unable to exert its heat dissipation effect , At the same time, because the pipeline system is too long, the fluid flow resistance in the pipeline in the heat exchange plate is very large, resulting in a decrease in the energy efficiency of the system. In addition,...
