Description

Technical Field

[0001] The utility model relates to the technical field of aluminum heat sink processing, in particular to a printed circuit board processing and leveling device. Background Art

[0002] Aluminum heat sink is a radiator material, widely used in various electronic equipment and industrial equipment, such as computers, mobile phones, televisions, transformers, generators, motors, etc. These devices will generate a lot of heat when running at high load for a long time, and heat sinks are needed to maintain the stable operation of the equipment. In addition, aluminum heat sinks also have important applications in the automotive industry, especially in automobile engine cooling systems, which can effectively reduce the operating temperature of the engine and improve the fuel efficiency and service life of the car. In the manufacturing process, aluminum heat sinks are often made of die casting, extrusion, stamping, sheet metal and other processes. The die casting process is to inject aluminum alloy liquid material into an aluminum mold, and after high pressure and high temperature treatment, an aluminum heat sink with a complex structure is formed. The extrusion process is to extrude aluminum alloy bars into shape and then cut them. The stamping process is suitable for aluminum sheets with a thickness of less than 3 mm. The aluminum sheet is stamped into an aluminum heat sink with a specific size and shape through the pressure of the mold and machinery.

[0003] The performance of aluminum heat sinks is affected by many parameters such as their size, material, shape, surface treatment, etc., including the interference of dust attached to the outside on their thermal conductivity. However, the structure of existing aluminum heat sinks is relatively simple, and a large amount of dust will be attached to the aluminum heat sink exposed to the outside during use. The continuously accumulated dust will hinder the contact area between the aluminum heat sink and the external environment, resulting in the inability to quickly exchange heat between the internal heat sink and the external environment.
