Abstract

The invention provides a liquid cooling heat dissipation apparatus and a motor controller. The liquid cooling heat dissipation apparatus comprises a substrate and a cooling liquid channel formed in the substrate; at least one heat conducting lug boss which protrudes out of the upper surface of the substrate is arranged on the substrate; a first mounting station used for mounting a power device is arranged on the side surface of each heat conducting lug boss; a lug boss water channel is formed in the heat conducting lug boss; and the lug boss water channel forms a part of the cooling liquid channel. By means of forming the lug boss water channel in the heat conducting lug boss and enabling the lug boss water channel to be one part of the cooling liquid channel, the heat conducting efficiency of the heat conducting lug boss can be greatly improved, and heat of the power device which is mounted on the surface of the heat conducting lug boss from the side surface can be taken away rapidly.

Description

technical field [0001] The invention relates to the field of motor controllers, and more specifically, to a liquid-cooled heat dissipation device and a motor controller. Background technique [0002] In motor controllers (such as electric vehicle controllers), in order to ensure the normal operation of heating modules such as IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor), it is necessary to use a water-cooled radiator to avoid excessive temperature rise. [0003] In the motor controller of electric vehicles, power devices are generally installed in two ways: flat mounting and side mounting. In many cases, in order to improve space utilization and reduce the volume of the whole machine, a vertical side installation structure is usually adopted. [0004] Such as figure 1 As shown in , it is a schematic diagram of side-mounted cooling for common power modules. The cooling liquid channel 14 is located between the structural member 12 and the seal...
