IGBT (Transistor bipolar de puerta aislada) Los módulos a menudo utilizan resortes de disco para fines de gestión térmica y aislamiento eléctrico..
Estos resortes de disco, También conocidas como lavadoras Belleville., Por lo general, están hechos de metal y se apilan en una serie..

En módulos IGBT, Los resortes de disco se utilizan principalmente para:

Distribución de presión: They help distribute pressure evenly across the module’s surface, asegurar un contacto adecuado entre los chips semiconductores, placa base, and cooling system. This is crucial for efficient heat dissipation.
Thermal Management: By applying pressure, disc springs help improve the thermal contact between the IGBT chips and the heatsink. This reduces thermal resistance and enhances the heat transfer from the chips to the cooling system, thus improving overall thermal performance.
Electrical Isolation: In some designs, the disc springs also provide electrical isolation between the power semiconductor devices and the heatsink or baseplate, preventing electrical contact and potential short circuits.

Overall, disc springs play a vital role in enhancing the reliability and performance of IGBT modules by ensuring proper thermal management and electrical isolation.
