Power module that possesses dampproofing dehumidification function

The utility model provides a power module that possesses dampproofing dehumidification function, including IGBT, drive plate, three proofings lacquer, radiator, PTC heating resistor, sealed glue, temperature detect switch and binding post, the PTC heating resistor is installed and is being used for for the radiating radiator of IGBT installation face, sealed peripheral edge of gluing the coating in IGBT pottery bottom plate and radiator combination department, temperature control switch installs on the radiator, binding post is used for providing the power for the PTC heating resistor. The utility model discloses the beneficial effect who creates is: through the PTC heating resistor, sealed glue, the mutually supporting of temperature detect switch and three proofings lacquer, accomplish dampproofing dehumidification function, but have thoroughly advantages such as efficient handling of condensation problem of dampproofing reliable, dehumidification, solved in and high humidity environment, the power module is long -time, and shut down or the storing process takes place that weing the condensation and the device that leads to damages the scheduling problem, has realized the quick dehumidification function of power module.
