Cooling plate and manufacturing method therefor

Abstract

The invention discloses a cooling plate and a manufacturing method. The cooling plate comprises a plate body and cover bodies. The plate body is provided with two side surfaces, and the plate body is provided with a plurality of internal flow channels, wherein the head and tail of each internal flow channel are respectively provided with openings on two side surfaces, so as to communicate with the external space. The two cover bodies are jointed with two side surfaces of the plate body, and are respectively provided with a flow guide part. The flow guide part and the adjacent two internal flow channels form a flow following region. The plurality of internal flow channels of the plate body are connected in series to form a continuous flow channel space through the flow following region.

Description

technical field [0001] The invention relates to a cooling plate and a manufacturing method thereof, in particular to a cooling plate and a manufacturing method thereof in which a plurality of inner flow channels are connected in series by a cover body joined to two sides of the plate body to form a continuous flow channel space. Background technique [0002] The cooling plate (or heating plate) is mainly used to dissipate the heat on the plate body by convection and / or heat the plate body after the inner flow channel is set and the liquid is injected into the plate body. Please refer to Figure 1A , Figure 1B The U.S. Patent No. US7480992 patent discloses the structure and manufacturing method of the existing cooling plate (or heating plate). The top plate 12 is covered on the top surface of the metal bottom plate 10, and the friction stir welding method is applied on the two sides of the circle corresponding to the channel 11, or the metal bottom plate 10 is fixed by usin...

AI Technical Summary

Problems solved by technology

[0003] In the aforementioned existing construction methods, there are quite a lot of shortcomings. First, the processing and manufacturing of the grooves on the metal base plate is very time-consuming and produces a large amount of waste;

[0004] Furthermore, when joining the metal bottom plate and the metal top plate, the welding bead must be applied along the channel, so there are very dense and large number of weld bead, the welding deformation is large, and it is difficult to maintain the flatness of the workpiece;

[0005] In addition, if it is implemented by screwing and fixing, the distance between the screw parts must be very small and must be sealed with an O-ring to seal the channel, so that the cooling plate is biased against the screw parts, which affects the heat transfer effect

[0006] In addition, with the existing metal processing method, the channel includes the rewinding part, so it is not conducive to splicing or cutting to form more various channels, and it is impossible to achieve customization and modularization.
