4results about How to "Consistent heat dissipation" patented technology

The application relates to the technical field of electric machines, in particular to an axial flux motor. The axial flux motor comprises an output shaft, a stator and an adjusting mechanism, the stator comprises a plurality of iron cores, an installation channel is formed in the middle of each iron core, and the installation channel is filled with cooling liquid. The adjusting mechanism comprises a plurality of adjusting components, and each adjusting component comprises a heat equalizing ring. The heat equalizing ring is used for contacting the iron core to enhance the heat dissipation effect of the iron core. A silk screen is arranged in the heat equalizing ring, and the heat equalizing ring is filled with working liquid. The overall density of the heat equalizing ring is smaller than the density of the cooling liquid. When the output shaft is vertically arranged, the heat equalizing ring increases the contact area between the heat equalizing ring and the upper part of the iron core through floating, so as to compensate the influence of gravity on the capillary effect and realize uniform heat dissipation of the upper part and the lower part of the iron core. The axial flux motor is provided to solve the problems of low heat dissipation efficiency and uneven heat dissipation of the existing axial flux motor.

This invention discloses a cooling device and a controller for a controller. The cooling device for the controller includes a housing and a flow control structure. The housing defines a cooling channel. The flow control structure is disposed within the cooling channel and includes multiple partition plates. The partition plates divide the cooling channel into multiple liquid flow spaces in the direction of liquid flow within the cooling channel. Multiple through holes are formed on the partition plates, connecting two adjacent liquid flow spaces. In the direction of liquid flow within the cooling channel, the flow area of ​​the multiple through holes on the upstream partition plate is smaller than that on the downstream partition plate. This results in a more consistent overall heat dissipation effect, a more balanced overall temperature, and better cooling performance, making the controller safer to operate and extending its service life.
