Aluminum alloy die casting

Abstract

The invention relates to the technical field of die castings, in particular to an aluminum alloy die casting. The aluminum alloy die casting comprises a base and an amplitude reduction assembly, a heat dissipation copper block is fixedly embedded in the base, a plurality of trapezoidal cavities distributed at equal intervals are formed in the heat dissipation copper block, an area expanding assembly used for expanding the area of the heat dissipation copper block and a refrigeration assembly are installed on the heat dissipation copper block, and the amplitude reduction assembly used for reducing the amplitude of the base is installed in an installation cavity formed in the base. Hydraulic cylinders are started to push connecting rods to slide outwards, so that heat dissipation plates on the connecting rods slide out of the trapezoidal cavities, on one hand, the ventilation rate of the trapezoidal cavities is increased, on the other hand, the overall area of the heat dissipation copper block is increased, the heat dissipation rate of an installation element is increased, by opening semiconduction refrigeration sheets and a submersible pump in the refrigeration box body, cooling liquid continuously and circularly flows along with liquid storage boxes, heat absorption pipes, flow guide pipes and the refrigeration box body, the heat absorption pipes can absorb heat on the heat dissipation copper block, and the heat dissipation rate is further increased.

Description

technical field [0001] The invention relates to the technical field of die castings, in particular to an aluminum alloy die casting. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die-casting machine, and passes through the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are usually called die castings. Die-casting parts have different names in different places, such as die-casting parts, pressure castings, die-casting parts, die-casting aluminum, die-casting zinc parts, die-casting copper parts, copper die-casting parts, zinc die-casting parts, aluminum die-casting parts aluminum die-casting parts, aluminum die-casting parts Alloy castings, aluminum alloy die-casting parts, etc...

Problems solved by technology

However, the fin types of existing copper tube radiators are mostly convex heat sinks, which have low wind resistance and low heat transfer system, and cannot meet specific heat dissipation solutions, and cannot be directly installed on high-heating equipment. use
