Abstract

The invention discloses a tool used for filling rubber into a power module and a rubber filling method thereof, wherein, the tool for filling rubber comprises a filling box and a rubber limiting mould that can seal the inner space of the power module, the filling box is communicated with a vacuum generator, the rubber limiting mould is put in the filling box and connected with a rubber filling device. The rubber filling method for a power module is that: in vacuum condition, the heat-conducting rubber is pumped and filled between two PCB plates of the power module. The tool used for filling rubber into a power module, which is clean, convenient and practical, can fill the heat-conducting rubber between the two PCB plates of the power module. The rubber filling method for a power module is simple, and fast and has good filing effect.

Description

technical field [0001] The invention belongs to the technical field of power supply heat dissipation, and relates to a tool and a glue filling method for a power supply module. Background technique [0002] The heat dissipation of the power module to ensure its normal operation has always been a problem that needs to be solved. At present, the best way to solve the heat dissipation problem is to lay a film with good thermal conductivity on or around the module to dissipate heat. However, the power module has no shell, and the element Due to the different arrangement of devices, the heat dissipation film and the module cannot be tightly combined, and the heat dissipation effect is not very satisfactory. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a clean, convenient and practical tool for filling the power module with heat-conducting glue between two PCB boards of the power module quickly. [0004] The furthe...
