The heat sink is a device for radiating the easily heated electronic components in electrical appliances. It is usually made of aluminum alloy, brass or bronze in the form of plates, sheets, or multiple sheets. Generally, the heat sink should be coated with a layer of thermal conductive silicone grease on the contact surface between the electronic components and the heat sink during use, so that the heat from the components can be more effectively transmitted to the heat sink, and then distributed to the surrounding air through the heat sink. As far as the heat sink material is concerned, the thermal conductivity of each material is different. The thermal conductivity is arranged from high to low, namely silver, copper, aluminum and steel
The production process of heat sink is as follows: product demand - drawing development - mold making - mold testing (extrusion of aluminum profiles) - cutting, CNC processing - confirmation of functional size samples - color confirmation (anodizing or oxidation spraying others) - production input - packaging (inspection) - delivery
The radiator plays an important role in the composition of the radiator. In addition to the active cooling of the fan, the evaluation of a radiator depends largely on the heat absorption capacity and heat conduction capacity of the radiator itself
