Device for cooling inverter for hev
2006
A device for cooling an inverter for an HEV(Hybrid Electric Vehicle) is provided to improve the degree of freedom in installation and extend a lifetime by reducing a temperature deviation of an element for cooling regardless of temperature reduction of a heat discharging plate and a position of the element. A refrigerant convection space(30) is formed inside a heat discharging plate(10). A porous body(60) is made of a thermal conductive material and attached to the inner surface of the refrigerant convection space. A refrigerant(40) is filled in the refrigerant convection space. The refrigerant is convected from a central position of the refrigerant convection space to both sides thereof through heat diffusion generated from an element to discharge the heat and then returned to the central position.
