Embodiment Construction
[0016] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0017] like figure 1 As shown, a motor casing cooling structure for an electric vehicle includes a motor casing 1 and an iron core 7, and windings 5 are installed on both ends of the iron core 7, and the number of windings 5 is two. The iron core 7 is installed in the motor housing 1 , and the iron core 7 is in interference fit with the motor housing 1 , and the motor housing 1 provides an installation space for the iron core 7 . The motor housing 1 is embedded with a circulating water channel 9, and the circulating water channel 9 and the circulating oil channel 6 can be directly pre-cast in the motor housing 1 as a whole according to the prior art process when the motor housing 1 is cast. The circulating water channel 9 surrou...

The invention relates to a motor housing cooling structure for an electric car. Compared with the prior art, the motor housing cooling structure solves the problem that a motor cooling means can not meet the needs of actual use. A water circulation channel is embedded in a motor housing, the water circulation channel encircles the outer periphery of an iron core, a water inlet and a water outlet are arranged in the outer wall of the motor housing, one end of the water circulation channel communicates with the water inlet, and the other end of the water circulation channel communicates with the water outlet. Two oil path cooling assemblies are embedded in the motor housing, and correspond, in position, with windings on the two ends of the iron core. Each oil path cooling assembly comprises an oil circulating path embedded in the motor housing, and an oil inlet pipe is inserted in the outer wall of the motor housing and communicates with the oil circulating path. An oil spraying port is arranged in the inner wall of the motor housing and communicates with the oil circulating path. and the oil spraying direction of the oil spraying port faces the winding. Oil cooling and water cooling of the motor are realized.
Description
technical field [0001] The invention relates to the technical field of electric vehicle motors, in particular to a motor housing cooling structure for electric vehicles. Background technique [0002] The cooling methods of motors and controllers for electric vehicles are generally divided into air cooling, water cooling or oil cooling. Air cooling is configured for low-power motors and controllers. High-power motors and controllers generally choose water cooling or oil cooling for cooling. The water-cooling method of electric vehicles is to install cooling equipment on the vehicle to dissipate heat for the motor and controller. The distance from the end of the winding is relatively close, which affects the insulation of the motor, has low reliability, and has potential safety hazards. Therefore, how to combine water cooling and oil cooling to design a safe and effective cooling structure has become an urgent technical problem to be solved. Contents of the invention ...
