Problems solved by technology

[0003] Existing flat fins or cylindrical fins are all made by die-casting process and integrally formed with the base. Due to the mold release requirements in the die-casting process, both flat fins and cylindrical fins require approx. A draft angle of 2 to 5 degrees makes the overall weight heavier and its aspect ratio (Aspect ratio) is often below 10, resulting in too thick fins and fewer fins in a heat sink of the same size. Insufficient heat dissipation area and poor heat dissipation performance

Abstract

In a heat sink module and a manufacturing method thereof, the method includes steps of: forming a heat dissipation fin set by aluminum extrusion process, wherein the heat dissipation fin set includesa plate, a plurality of fins extending from one side of the plate and being arranged spaced apart from one another, and a joint portion formed on the other side of the plate; placing the plate in a mold; injecting molten metal into the mold; forming a base by die-casting of the molten metal. The plate and the joint portion are wrapped by the base. The joint portion forms a connection structure including a bump and a notch fitted with the bump, so as to connect and fix the base and the heat dissipation fin set. The heat sink module has the strengthened connection structure and the fins with a superior aspect ratio.

Description

Technical field [0001] The invention relates to a heat dissipation module and a manufacturing method thereof, in particular to a heat dissipation module with a strengthened joint structure and fins arranged in a better aspect ratio by combining different molding processes. Background technique [0002] When electronic products are in operation, unnecessary heat energy is generated due to the influence of impedance. If these heat energy cannot be effectively eliminated and accumulate inside the electronic products, electronic components may malfunction or be damaged due to rising temperatures. Therefore, the quality of the heat sink greatly affects the operation of electronic products. [0003] Existing flat fins or cylindrical radiating fins are made by die-casting process and integrally formed with the base. Due to the demoulding requirements in the die-casting process, both flat fins and cylindrical radiating fins need to be approximately The draft angle of 2 to 5 degrees makes ...
