Description
Technical Field
The utility model belongs to the technical field of the IGBT heat dissipation, concretely relates to IGBT module cooling device.
Background
Insulated Gate Bipolar Transistors (IGBTs), abbreviated as IGBT modules. With the continuous development of the IGBT module, the integration level of the IGBT module is required to be higher and higher, but the high integration level is necessarily accompanied by a large amount of heat generation. When the IGBT chip module works, the heat flow density is high, the temperature rising speed is high, heat is easy to accumulate in a large amount in the electronic element, and the service life of the electronic element is greatly reduced along with the increase of the service temperature. Especially when the temperature exceeds a certain temperature, the element is directly burned out.
Traditional IGBT heating components and parts generally adopt the forced air cooling heat dissipation mode, because the specific heat capacity of air is less, the heat of taking away through the air is less relatively, can satisfy the heat dissipation demand to the less IGBT components and parts of calorific capacity, but in the face of the IGBT component that the structure is compacter day by day, power increases day by day, traditional heat dissipation mode can't satisfy the heat dissipation demand, in addition, current cooling device is because the restriction of casting level, the ubiquitous problem that cooling capacity is not enough.
