Charge and discharge module and its inductance element

Abstract

The invention relates to a charging and discharging module and an inductance element thereof. The inductance element includes: a mounting shell, including at least two shell walls, the shell walls are connected to the shell walls, refrigerant flow channels are arranged in the shell walls, and the refrigerant in each shell wall The flow channels are connected; the installation shell is filled with potting glue; the coil is fixed in the installation shell through the potting glue. Arrange the refrigerant channel in the adjacent shell wall of the installation shell, and the refrigerant flow channel in the adjacent shell wall communicates, compared with the scheme in the prior art where the coil exchanges heat with the cold plate through one side of the installation shell, the increase The area for heat exchange between the coil and the outside world is reduced, and the heat dissipation efficiency of the coil is improved; and the heat exchange between the coil and the shell wall is directly performed, which shortens the heat transfer path, increases the heat dissipation speed, and makes the heat dissipation effect 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...
