Abstract

The invention discloses a cooling device of a power converter and the power converter, and belongs to the technical field of power converters. The cooling device of the power converter comprises a shell and a lower cover plate, a communication groove and a mounting cavity are formed in the shell, openings of the communication groove and the mounting cavity face opposite directions, and a flow guide rib is arranged on the communication groove to separate the communication groove; the lower cover plate is arranged on the shell, the lower cover plate and the communication groove form a waterway channel, and a diversion rib divides the waterway channel into shunting channels. The power converter comprises the cooling device of the power converter. According to the cooling device of the power converter and the power converter, the diversion rib is arranged in the communication groove to reduce a cooling liquid flowing dead zone, and a heat dissipation part is arranged in the mounting cavity, so that heat conduction between the to-be-cooled element and the waterway channel is improved, and the cooling efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of power converters, in particular to a cooling device for a power converter and a power converter. Background technique

[0002] Existing power converters use water-cooling to cool internal components. The power converter includes a straight-through water pipe. The water pipe and the housing are assembled together. The heat generated by the internal components is cooled by the cooling liquid in the water pipe. There will be poor circulation in the water pipe. If the coolant flow rate is too high, it will easily cause impact on the side wall of the water pipe. At the same time, there will be a dead zone in the coolant flow, and the cooling effect will be poor. Contents of the invention

[0003] An object of the present invention is to provide a cooling device for a power converter to improve cooling efficiency.

[0004] For reaching this purpose, the present invention adopts following technical scheme: ...
