Charging and discharging module and inductance element thereof

Abstract

The invention relates to a charging and discharging module and an inductance element thereof, and the inductance element comprises an installation housing which comprises at least two housing walls, wherein the housing walls are connected, refrigerant flow channels are arranged in the housing walls, and the refrigerant flow channels in the housing walls are communicated. The installation housing is filled with a pouring sealant. The element also comprises a coil fixed in the installation housing through pouring sealant. Compared with a scheme that in the prior art, coil exchanges heat with acold plate through one side face of the installation housing, a heat exchange area between the coil and the outside is increased, and the heat dissipation efficiency of the coil is improved due to the fact that the refrigerant flow channels are arranged in the adjacent housing walls of the installation housing and communicated. The coil directly exchanges heat with the housing wall, so that the heat transfer path is shortened, the heat dissipation speed is increased, and the heat dissipation effect is better.

Description

technical field [0001] The invention relates to a charging and discharging module and an inductance element thereof. Background technique [0002] In the prior art, if an electric vehicle wants to achieve fast charging, the output power of the power module must be increased, but the increase in output power will also cause serious heating of some components, and even stop working and explode. Traditional air-cooled heat dissipation can no longer meet the heat dissipation requirements of these high-power components, so water-cooled methods are mostly used in the prior art to dissipate heat from high-power components. [0003] Such as figure 1 As shown, it is an arrangement structure of a power module in the prior art. The power module includes a box body, and components and a cold plate 10 for cooling and dissipating the components are arranged inwardly. There are two types, which are the IGBT module and the inductance element 12 respectively. The box is also provided with...
