Copper ofern be the material for heat sinks because
1. Copper has excellent thermal conductivity, as it can quickly transfer heat to the heat sink and dissipate it into the surrounding air through the outer surface of the heat sink. This means that heat sinks made of copper material can quickly and effectively reduce equipment temperature.
2. Copper has good thermal stability. Copper can maintain stable performance in high temperature environments and is not easily deformed or burn-in. This makes copper heat sinks an ideal choice for high-performance electronic devices, computer processors, and other heat sources.
3.Copper heat sinks have high processing performance. Copper can be processed through various processes such as casting, welding, cutting, etc., which makes it possible to manufacture heat sinks with complex shapes. Meanwhile, copper heat sinks can also enhance their corrosion resistance and aesthetics through surface treatment processes.
So copper has good thermal conductivity, high temperature resistance, and easy processing, making it widely used in heat sinks.
But there are also many types of copper, and the main ones used in heatsink are brass copper and purple copper(C1100) . What is the difference between the two?
1, Compositional differences
Brass is an alloy composed of copper and zinc, with copper content typically ranging from 60% to 80%. Purple copper is a type of pure copper, typically with a purity of over 99.9%, and does not contain any other metallic elements.
2, Physical performance
There are certain differences in the physical properties of brass compared to purple copper. Brass has high hardness, high tensile strength, and good ductility. Purple copper has better conductivity and thermal conductivity than brass, and also has better ductility and plasticity.
3, Corrosion resistance
Brass has good corrosion resistance and can maintain good stability in humid and corrosive environments. However, purple copper has poor corrosion resistance and is easily affected by corrosion such as oxidation and sulfurization, so special protective measures need to be taken in some special environments.
5, Price
There is also a certain price difference between brass and purple copper. Due to the high purity and complex production process of copper, its price is usually higher than that of brass. Brass, on the other hand, contains a certain amount of zinc and has a relatively simple production process, so its price is relatively low.
Application of brass and purple copper in heat sink
We can see from the difference between brass and purple copper that their applications on heat sinks are also different.
Brass has good oxidation resistance and corrosion resistance, but its thermal conductivity is not as high as copper, so it is mostly used for structural components, such as water cooling plate joints.
Purple copper is mostly oxygen free copper, which has high purity and good thermal conductivity, so it is mostly used for heat pipes, water cooling plate pipelines, etc.
The embedded copper tube cold plate that combines brass and purple copper fully utilizes the advantages of both: purple copper is responsible for rapid heat conduction, while brass provides corrosion resistance and structural stability, thereby achieving faster heat transfer, stronger oxidation resistance, and longer service life.
