Controller and method for manufacturing a controller

By using a thermally conductive heat transfer element in the controller to thermally connect with the housing, and by using a compressible heat transfer medium to fill the gap, the problem of low heat transfer efficiency caused by a large gap between the heat-generating device and the housing is solved, and efficient heat dissipation that can adapt to different tolerances and geometries is achieved.

AI Technical Summary

Technical Problem

Existing technologies struggle to effectively bridge the relatively large gap between the heating element and the controller housing, resulting in low heat transfer efficiency and an inability to accommodate large component and manufacturing tolerances.

Method used

The heat transfer element with good thermal conductivity is thermally connected to the shell, and the heat transfer is optimized by using a heat transfer medium. At the same time, the gap is filled by a compressible heat transfer medium to compensate for the tolerance, so as to achieve efficient heat transfer from the heating device to the shell.

Benefits of technology

It achieves effective heat dissipation even with large gaps, adapts to different geometries and tolerances, and ensures stable operation of the controller.
