Method for producing column-shaped radiator

Abstract

The invention relates to a manufacture method of columnar radiator, which mainly comprises main procedures such as (1) extraction and extrusion molding, (2) cutting into column shape, (3) continuous punching and milling mold and (4) tightly combining cooling fins. During extraction and extrusion molding, a strip extrusion mold with a plurality of parallel and adjacent slab blocks is formed by extraction and extrusion and is cut into single extrusion blocks. During cutting molding, the slab block is cut along the vertical direction to form a plurality of columnar bodies. During continuous punching and mold milling, a plurality groups of punching molds sequentially subject the plurality of columnar bodies to continuous coarse punching and fine punching to precise shape the columnar bodies. Accordingly, the cooling fins can be sequentially matched with and sheathed in the plurality of columnar bodies to fast assemble a columnar radiator.

Description

technical field [0001] The invention relates to a method for manufacturing a columnar heat sink. The manufacturing process includes (1) extrusion molding (2) cutting into a column shape (3) punching and shaping with a continuous punching die (4) tightly fitting a plurality of heat sinks Combined with other processes, a columnar radiator can be quickly manufactured. Background technique [0002] The conventional heat sink is mainly composed of a heat sink module and a base, and the heat sink module is formed by stacking a plurality of heat sinks adjacent to each other at intervals, and those known in the art also have the ability to cope with high heat dissipation power If required, it can be combined with more than one heat pipe. The heat sink or base is usually made of aluminum or copper metal, and the base (copper base or aluminum base) is used to guide the crystal heat source to achieve heat dissipation. [0003] In addition, conventional small heat sinks also have a plu...

Problems solved by technology

[0003] In addition, the known small heat sink also has a plurality of heat dissipation plates arranged in parallel at intervals directly integrally formed on the base, so that the base guides the crystal heat source to the heat dissipation plate to achieve the purpose of heat dissipation, but this type of small heat sink is small in size , simple structure and low cost, but the heat dissipation power is low, often unable to meet the requirements of general heat dissipation power; The cost is very high, and it is also not suitable for those who require general heat dissipation power; therefore, if the heat pipe radiator is used for crystals with low heat dissipation power requirements, the supply will appear to be in excess, resulting in unnecessary waste and uneconomical, but the existing small The heat sink is suspected of having insufficient heat dissipation power, so if the heat dissipation power of the heat sink and the crystal heat source can be matched, it is the best matching combination. The best heat sink design should refer to the one that can meet the actual heat dissipation needs. Radiator, any excess or deficiency is not suitable
