Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing;
[0016] see figure 1 , figure 2 and image 3 As shown, a motor cooling water jacket includes an annular sleeve body 1 and an annular sleeve cover 2. The annular sleeve cover 2 is placed outside the annular sleeve body 1. The annular sleeve body 1 is a double water channel. The inside of the annular casing is a closed cavity, which is divided into an outer water channel 4 with a serpentine labyrinth structure by a thin heat dissipation plate 5, and an inner water channel 3 with a groove 6 of a serpentine labyrinth structure is opened on the inner side of the annular casing. , the two ends of the annular sleeve body 1 are provided with a water inlet 7 and a water outlet 8 communicating with the water channel; Joint 9 and outlet water pipe joint 10. The annular cover 2 is provided with an axial mounting hole 11. A sealing ring is provided between the connecting surface of...

The invention relates to a motor cooling water jacket. The motor cooling water jacket comprises an annular jacket body and an annular jacket cover, wherein the annular jacket body comprises two water channels; the inner part of the annular jacket body is a closed hollow cavity; the closed hollow cavity is separated by a thin heat radiation plate to form an outer water channel with a snake-shaped labyrinth structure, and an inner water channel with a groove with the snake-shaped labyrinth structure is formed in the inner side of the annular jacket body; a water inlet and a water outlet which are communicated with the water channels are formed in the two ends of the annular jacket body; a water inlet water pipe connector and a water outlet water pipe connector are arranged at the positions, corresponding to the water inlet and the water outlet of the annular jacket body, of the annular jacket cover; the annular jacket cover sleeves the annular jacket body. The inner water channel is in direct contact with a motor, and the outer water channel is used for cooling the inner water channel, so that the cooling effect is good; the motor cooling water jacket has the advantages of compact structure, inconvenience for installation, good sealing performance, simple water channel structure and convenience for machining.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a motor cooling water jacket. Background technique [0002] The heat exchange in the motor directly affects the performance of the motor. In recent years, with the development and development of electric vehicles, the role of motors in vehicles is not only to start motors and air-conditioning motors, but to use motors as main drive or hybrid drive motors. New energy vehicles require the drive motor to have the characteristics of high electromagnetic load, high energy density, high speed, and low heat generation. However, when the drive motor of a pure electric vehicle operates under heavy load or continuous climbing, the motor will generate a large amount of energy. of heat. If the heat inside the motor cannot be taken out by the surrounding refrigerant in time, the operating efficiency will be reduced and the life of the motor will be shortened.
