An IGBT (insulated gate bipolar transistor) is a composite fully-controlled voltage-driven power semiconductor device consisting of a BJT (bipolar junction transistor) and an MOS (insulated gate field effect transistor), and has the advantages of both high input impedance of the MOSFET and low conduction voltage drop of the GTR. The IGBT integrates the advantages of the two devices, and has small driving power and reduced saturation voltage. The method is very suitable for being applied to high-power equipment with direct-current voltage of 600V or more, such as high-power mesh belt furnace equipment. The IGBT module is a modular semiconductor product formed by bridging and packaging an IGBT (insulated gate bipolar transistor module) and an FWD (freewheeling diode module) through a specific circuit, and the packaged IGBT module can be directly applied to equipment. The IGBT module has the characteristics of energy conservation, convenient installation and maintenance and the like, most of the IGBT module is a modularized product in the market at present, and along with the promotion of concepts such as energy conservation, environmental protection and the like, the modularized product is more and more common in the market.
However, like other electronic devices, the IGBT module generates a large amount of heat during operation, and if the heat is not dissipated in time, the performance and the life of the IGBT module are affected.
