The heat sink is a device used to dissipate heat for components that are easy to heat. It is made of aluminum/copper materials with high thermal conductivity to make radiators of different shapes such as plate, sheet, and multiple pieces.
The heat dissipation efficiency of the heat sink not only depends on the characteristics of the high thermal conductivity of the heat sink material, but also the heat capacity of the heat dissipation medium of the heat sink and the effective heat dissipation area of the heat sink. The radiator materials are mostly made of copper and aluminum.
Copper has good thermal conductivity, is more expensive, difficult to process, too heavy, has a small heat capacity, and is easy to oxidize. Aluminum is lighter and has worse thermal conductivity than copper. Generally speaking, for heat sinks made of the same material and technology, the thicker the heat sink material and the larger the surface area, the better the heat dissipation effect.
Our heat sink mainly includes: aluminum extrusion + CNC machining large heat sink, FSW large heat sink, riveted heat sink, insert heat sink, heat pipe heat dissipation system, shovel heat sink, forged heat sink, application It is used to solve the heat dissipation solution of industrial automation, power & transmission, medical equipment, new energy transportation, instrument and testing equipment and other industries.
The principle of the insert radiator: Because the application requires higher and higher power density, it often exceeds the cooling limit of the traditional extruded aluminum radiator. This drives the demand for heat sinks to meet increased performance requirements. In the same volume, bonded fin heat sinks dissipate more heat than extruded aluminum heat sinks because they allow higher fin heights and tighter fin spacing. Higher fin density and aspect ratio provide a larger surface area.
Advantages of the fin heat sink: The pure aluminum fin material used for the fin heat sink has a thermal conductivity of 15% higher than that of the extruded AL6063 material, and the ratio of the height of the heat sink fin to the fin pitch is 30:1 Or higher (extruded fin ratio 20:1 max). The customizable design can optimize the substrate thickness, fin thickness, and fin spacing as needed to improve heat dissipation performance.
