Description
Technical Field
The utility model relates to an electronic equipment especially relates to the thermal dissipation that high-power electronic equipment such as server, network equipment, LED lamp, new energy automobile produced.
Background
The water-cooling heat dissipation technology is more and more widely applied to electronic equipment as an efficient heat dissipation scheme, a water-cooling plate is used as an important component of a water-cooling heat dissipation system and belongs to key and core components of the water-cooling heat dissipation system, and the design and manufacturing level of the water-cooling plate determines key technical indexes such as heat dissipation efficiency, reliability and the like of the heat dissipation system. The existing water cooling plate is limited by a welding process, the leakage risk is still high, and the water cooling heat dissipation is stopped in a few special application scenes and is not used in a large amount.
The heat pipe is a high-efficiency radiator, and the heat is quickly conducted by utilizing the phase change process that a liquid medium is condensed at the cold end after being evaporated at the hot end. The interior of the heat pipe is pumped into a negative pressure state and filled with proper liquid, and the liquid has a low boiling point and is easy to volatilize. The heat pipe is internally provided with a wick which is made of capillary porous materials. When one end of the heat pipe is heated, the liquid in the capillary tube is quickly vaporized, the vapor flows to the other end under the power action of heat diffusion, the vapor is condensed at the cold end to release heat, the liquid flows back to the evaporation end along the porous material under the capillary action, the circulation is not stopped until the temperatures at the two ends of the heat pipe are equal, and the heat diffusion of the vapor is stopped.
In application 201610615666.7, a plate-type liquid-cooled vapor chamber composite radiator is proposed, in which heat exchange tubes are disposed in a phase-change cavity similar to a heat pipe structure, and heat is dissipated by circulating flow of a liquid cooling medium in the heat exchange tubes, and the heat exchange tubes are arranged in the phase-change cavity in a bent manner. The spacing between the pipelines is generally larger than the diameter of the pipelines due to the limitation of the bending radius of the pipelines, and the flow resistance is too large when the pipelines are too small, so that the space waste in the phase change cavity is large, and the heat dissipation efficiency is low. The applicant proposes in application 201710927136.0 a water-cooling phase-change heat dissipation device, in which a porous flat tube or multiple tubes are used in a phase-change cavity to improve the space utilization rate in the phase-change cavity, but the water-cooling heat exchange area of the scheme is still difficult to improve, and the water channel welding is complex. The water cooling plate is a mature prior art, and is formed by using metals such as copper and aluminum as a bottom plate, processing fine radiating teeth through milling, shoveling, cutting and other processes, and then welding and sealing the fine radiating teeth with an upper cover, a joint and the like. The water cooling plate can greatly increase the water cooling heat exchange area and greatly reduce the production cost.

The inside of the water-cooling plate is processed with fine heat dissipation teeth, so that the water-cooling heat exchange area inside is enlarged as much as possible, and the heat dissipation efficiency is improved. Because the water-cooling plate is installed inside the phase change cavity, the upper surface and the lower surface of the water-cooling plate can dissipate heat, and heat dissipation teeth can be processed on the upper surface and the lower surface inside the water-cooling plate. The joint of the water cooling plate is integrally processed and formed by metal materials and penetrates through the phase change cavity to be installed, so that the welding line of the water cooling plate is completely encapsulated inside the phase change cavity.
