The aluminum stamping heat sink is made by using a professional stamping machine to press metal materials into the mold with a very high pressure percussion method to form the fins, and then cut, CNC machining and surface treatment. The stamping heat sink is a specific electronic Package type. This field has different processing methods to ensure the best fit and function. These heat sinks have a variety of mounting methods, including soldering tabs and pins, interference fit with the device through integrated clips or sliding functions, or screws And nuts and other through-hole hardware,
Most stamped heat sinks are surface treated to improve the heat dissipation and heat dissipation performance of natural convection applications,
It has a different process from extruded heat sink and toothed heat sink, which are professionally customized according to the different applications and requirements of customers. Our company will also give customers a solution for their choice according to the product itself.
Aluminum stamping heat sinks are widely used in electric/hybrid vehicles, rail transit, variable frequency home appliances, power engineering, renewable energy, and smart grids. It is one of the most important high-power mainstream devices in power electronics. With the expansion of my country's high-speed rail construction, power grid upgrades, large-scale applications of clean energy (wind energy, solar energy, etc.), energy conservation and environmental protection, etc., the IGBT industry chain ushered in a period of full-speed development.
Because the IGBT module is a high-power device, the IGBT device is the core of the power converter device, which generates a lot of heat during operation. However, the junction temperature range of the IGBT module during normal operation is -40°C-150°C, so to maintain the normal operation of the IGBT chip, a heat sink is needed to help it dissipate heat. The performance improvement of the IGBT power module largely depends on the heat dissipation performance. Improvement.
