Liquid-cooled cooling plate with composite casting structure

Abstract

The invention discloses a liquid-cooled cooling plate with a composite casting structure, which comprises a cast aluminum alloy bottom plate (1), a coiler (2), a pipe joint A (4), a pipe joint B (5) and a pipeline (3). The coiler (2) is an 'M'-shaped seamless stainless steel pipe, the pipe joint A (4) and the pipe joint B (5) are stainless steel pipes, and the pipeline (3) is a straight stainless steel pipe with two end closed. The coiler (2), the pipe joint A (4), the pipe joint B (5) and the pipeline (3) are disposed in the cast aluminum alloy bottom plate (1) and are fixed with the same. During working of the liquid-cooled cooling plate, the cast aluminum alloy bottom plate (1) requires various electronic elements for heat radiation, coolant is injected from the pipe joint A (4), and then flows through the coiler (2) to be discharged from the pipe joint B (5) to a secondary cooling system for dissipating heat of the electronic elements. The heat radiation efficiency of the cooling plate is improved and corrosion of the coolant to cooling pipelines of the coiler of the cooling plate is avoided.

Description

technical field [0001] The invention relates to a liquid-cooled cold plate, in particular to a liquid-cooled cold plate with a composite casting structure. Background technique [0002] At present, there are many types of liquid-cooled cold plates for cooling and heat dissipation, including: aluminum alloy bottom plate milling groove buried pipe type, aluminum alloy bottom plate deep hole processing type, aluminum alloy bottom plate milling pipe tailor welding type. The above-mentioned types of cold plates have their own characteristics. The aluminum alloy bottom plate milling groove buried pipe type is relatively large in contact thermal resistance because the pipeline and the bottom plate are glued with heat-conducting adhesive, and the contact thermal resistance is relatively large; the aluminum alloy bottom plate deep hole processing type The corrosion resistance of coolant is relatively poor, and the size of the cold plate cannot be too large due to the limitation of pr...
