AI Technical Summary

Benefits of technology

This technology improves how well an electric machine's power works when it generates more energy compared with older designs that had no significant impact on its own design or functionality. It introduces a new way to transfer waste heat from one part (the rotating parts) inside the housing into another area where there can better absorb this excessive amount of heat. By adding a special type of material called a heat pipes instead of traditional materials like iron powder, these improvements improve both efficiency and reliability during operation.

Problems solved by technology

This patents discuss how current techniques such as water or air can limit the efficiency with regards to heat removal from an electrical machine (M) due to limitations like insufficient space between certain parts within the M itself that require longer periods during their use compared to other components. Additionally, existing solutions involve adding materials into the motor design without addressing this issue, making them challenging to improve upon when they work properly.

Abstract

The invention discloses a motor stator heat radiation structure. A motor comprises a housing, a stator core disposed in the housing and a motor winding wound on the stator core. The housing is internally provided with multiple heat conduction pipes each with two enclosed ends, the housing is provided with multiple vertical cooling channels, an upper horizontal radiating pipe and a lower horizontal radiating pipe of each heat conduction pipe are embedded into the stator winding, and vertical cooling pipes of the heat conduction pipes are disposed in the cooling channels. According to the invention, the heat conduction pipes are additionally arranged for heat dissipation, the original heat dissipation effect of the motor for the stator core is maintained, at the same time, heat generated by the stator winding is directly brought into the water channel of the housing by the heat conduction pipes through the end portion of the stator winding, and finally cooling media in the cooling channels bring the heat of the motor out. Under the condition that an original motor structure is not substantially changed, the heat dissipation performance of the whole motor is improved, the structure is simple, the cost is quite low, and the stability and the safety of the motor are greatly improved.
