Heat radiator and manufacturing method thereof

Abstract

The invention relates to the technical field of heat radiation, in particular to a heat radiator and a manufacturing method thereof. The heat radiator is composed of cooling fins, a fixed medium cavity fixedly connected with the cooling fins, a heat transfer contact base body movably connected with the fixed medium cavity and a connecting piece arranged on the upper surface and the lower surface of the heat transfer contact base body. Then, the fixed medium cavity is included in the heat radiator, and media in the fixed medium cavity are defined as heat conduction oil. Then, a large amount of heat can be transmitted out of the heat transfer contact base body through the performance of the heat conduction oil. Then, heat exchange is achieved, the heat radiation effect is improved through rotation and large-area treatment of the cooling fins, and the heat radiation effect on equipment needing heat radiation treatment is guaranteed. In the manufacturing process, the cooling fins and the fixed medium cavity are formed in an ultrasonic welding manner or a manner of being squeezed into a whole; then the character that heat radiation of welding blocks is uneven due to a tradition welding manner is reduced; and then the heat radiation performance of the heat radiator is improved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation, in particular to a radiator and a preparation method thereof. Background technique [0002] At present, there are many processing technologies for heat sinks, such as the patent No. CN201210107274 "radiator and its manufacturing method", which is composed of a circuit substrate and a heat sink, and the manufacturing method includes: preparing brazing material, wherein, in the Outside the range of the area directly below, the brazing material has a space corresponding to the stress relief space, and in the range of the area directly below, the brazing material has a volume smaller than that formed in the contrast area. An additional space of the volume of the space in the space; disposing the brazing material at the bonding interface of the rear metal layer; heating the brazing material to a temperature higher than the melting temperature so as to melt the brazing material; and The molte...

Problems solved by technology

[0003] Nevertheless, the above-mentioned heat sink manufacturing technology still has the difficulty of improving the performance of the heat sink, especially the heat dissipation performance to the optimum, which leads to the low heat dissipation performance of the manufactured heat sink, and then affects the low service life of the heat dissipation equipment. This will further affect the quality of the entire product. Therefore, this researcher provides a new way of thinking for the field of radiator technology by exploring and combining the theory of medium heat transfer, combining the medium heat transfer technology and the heat dissipation technology of heat sinks.
