A heatsink is a device used to dissipate heat from heat-generating electronic components in electrical appliances. They are typically made of aluminum alloy, brass, or bronze, and can be in the form of plates, sheets, or multiple sheets. Diamond is also used in heatsink manufacturing, especially diamond heatsinks produced using the MPCVD method, which have applications in high-end fields.
For example, the CPU (Central Processing Unit) in a computer requires a fairly large heatsink. Power transistors, horizontal output transistors, and power amplifier transistors in a television all require heatsinks. In electric vehicle battery cooling technologies, such as LSC (Liquid Crystal Array) technology, metal heatsinks are added between the battery cells to improve heat dissipation.
Generally, during use, a layer of thermal grease is applied to the contact surface between the electronic component and the heatsink. This allows the heat generated by the component to be more effectively conducted to the heatsink, and then dissipated into the surrounding air.
