Copper base aluminum fin heat sink
The radiator is a device or instrument that transfers the heat generated by the computer or power supply during the working process in time to avoid affecting its normal operation. Common radiators (heat sinks) can be divided into air cooling, heat pipe radiator, liquid cooling, semiconductor refrigeration, compressor refrigeration, etc. according to the heat dissipation method.

Computer radiator overview
A large number of integrated circuits are used in computer components. As we all know, high temperature is the enemy of integrated circuits. High temperature will not only cause unstable operation of the system, shorten the service life, and may even burn some parts. The heat that causes high temperatures does not come from outside the computer, but inside the computer, or inside the integrated circuit. The role of the radiator is to absorb the heat, and then radiate it to the inside or outside of the case to ensure the normal temperature of the computer components. Most radiators absorb heat by contacting the surface of heating components, and then transfer the heat to a distance through various fans. For example, in the air in the case, the case fan transmits the hot air to the outside of the case to complete the heat dissipation of the computer.

Calculator heat sink material
The material of the heat sink refers to the specific material used for the heat sink. The thermal conductivity of each material is different, arranged from high to low in terms of thermal conductivity, which are silver, copper, aluminum, and steel. However, it would be too expensive to use silver as a heat sink, so the best solution is to use copper. Although aluminum is much cheaper, it is obviously not as good as copper in thermal conductivity (only about 50% of copper). Commonly used heat sink materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is more expensive, difficult to process, too heavy (many pure copper radiators exceed the weight limit of the CPU), small heat capacity, and easy to oxidize. But pure aluminum is too soft to be used directly. The aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than copper. Some radiators take their own strengths and embed a copper substrate on the aluminum alloy radiator base. For ordinary users, the use of aluminum heat sinks is sufficient to meet the heat dissipation requirements.
