Thermal conductivity of heat sink in transformer tank

In the field of power transmission and transformer technology, heat sink is an important thermal management component, and its thermal conductivity is crucial to ensure the stable operation of equipment. Basic understanding of heat sink thermal conductivity in transformer tank: The thermal conductivity of heat sink refers to the ability of its material to conduct heat. In the transformer tank, the heat sink is usually made of metal materials with high thermal conductivity, such as aluminum alloy or copper alloy. These materials have good thermal conductivity, which can effectively transfer the heat generated inside the transformer to the surface of the heat sink quickly, and achieve effective cooling through the heat exchange between the heat sink and the surrounding air.
Key factors to improve heat transfer efficiency
The design of heat sink in transformer tank is not only to increase the surface area, but also includes the following key factors: Material selection: Good thermal conductive materials are the basis for ensuring the efficient operation of heat sink. Aluminum alloy is widely used because of its light weight and good thermal conductivity, while copper alloy is favored in some high-performance applications because of its higher thermal conductivity.
Heat sink structure design: The geometry and structural design of the heat sink have an important impact on its heat transfer efficiency. Through the rational design of the sheet structure and arrangement, the contact area between the heat sink and the surrounding air can be increased, and the heat transfer rate can be improved.
Surface treatment technology: such as anodizing or special coating can improve the surface performance of the heat sink, enhance its corrosion resistance and heat transfer efficiency, thereby further improving the overall heat dissipation performance.
