Example Embodiment

[0013] The principle and structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0014] Such as Figure 1 to Figure 4 As shown, an embodiment of the present invention provides a power module with a cofferdam. The power module is an open power module. The specific structure includes a bottom plate 1. The bottom plate 1 is surrounded by a cofferdam 2 that surrounds the bottom plate 1 into a closed environment. , Can be used to fill thermal conductive glue.

[0015] According to safety requirements, the distance between the conductive metal and component pins on the circuit board 3 and the chassis is more than 2.0mm, so there are multiple support posts 4 with screw holes on the bottom plate, and the circuit board 3 can be fixed on On the support pillars 4, these support pillars 4 can not only locate the height of the installed circuit board 3, but also position the distance between the edge of the circuit board 3 and the cof...

Abstract

The invention discloses a power supply module with a cofferdam, which comprises a bottom plate, a cofferdam arranged around the bottom plate, multiple supporting columns with screw holes arranged on the bottom plate, a circuit board fixed on the supporting columns via screws, electronic elements arranged on the upper surface and the lower surface of the circuit board, a lower heat conductive adhesive layer filling the cofferdam to fill the lower surface of the circuit board and an upper heat conductive adhesive layer laying the upper surface of the circuit board and surrounding the electronic elements. Cooling can be well carried out, normal operation of the power supply module is protected, and the service life of the power supply module is longer.

Description

technical field [0001] The invention relates to a power supply module with a cofferdam, in particular to a method for a power supply module with a cofferdam with better heat dissipation performance. Background technique [0002] Since electric drive energy has various advantages such as environmental protection and energy saving, open power supply modules are widely used in pure electric vehicles, hybrid electric vehicles and forklifts and other environmentally friendly energy vehicles. Since the energy conversion of the electric drive requires work, the power conversion will cause the frequency converter (the core is: electronic components) to generate heat. As the working time increases, the heat of the frequency converter also needs to be released by conduction. The existing power module cannot Good heat dissipation makes the temperature of the power module of the electric vehicle too high when doing work, which affects the service life. Contents of the invention [00...
