How to choose materials for Electronics heat sinks?

Electronic radiator is a common durable consumer product, mainly divided into: electronic radiator, solid-state radiator, power radiator, insert radiator. Its main function is heat dissipation, followed by considerations of energy saving, durability, decoration, and low price. The vast heating area in my country has gradually expanded from the original north of the Yangtze River to the south of the Yangtze River.

The application of radiators is also increasing year by year. With the improvement of application, the consumption of radiator products is also increasing year by year. The number of manufacturers has increased from more than 1,000 to nearly 4,000 today. The type and structure of radiator products Different materials are used, and there are cast iron, steel pipe, copper-aluminum composite, steel-aluminum composite, stainless steel-aluminum composite, and it should be said that they all have some advantages.

Cast iron radiators have good corrosion resistance and pressure resistance, and the lack is poor decoration. The advantage of steel radiators is that they can be manufactured in various shapes at will, and their decorative properties are relatively good, but the corrosion resistance is difficult to meet the water quality of domestic heat media, and the thermal efficiency is not as good as other radiators. Although the steel-aluminum composite radiator uses the amplifying function of aluminum fin heat conduction, the built-in does not change its lack.

Both stainless steel single-material radiators and steel radiators have the ability to produce various radiators with different shapes, but the heat transfer performance of stainless steel is not as good as that of steel radiators. It is difficult to use high temperature welding to destroy its physical properties, but it has poor corrosion resistance, low temperature welding products are expensive, and the strength is difficult to prove.
