Description
Technical field
The utility model relates to motor case field, particularly relates to a kind of motor for pure electric vehicle casing structure with spirality cooling water pipe.
Background technology
Along with country promotes the development of new-energy automobile energetically, new-energy automobile especially pure electric automobile is applied in all trades and professions, as public transport, airport inside transport etc., in the power assembly of pure electric automobile, the most important thing is motor, at some oversize vehicles as in the structure of motor bus, exigent to motor, the volume of its motor is large, often the shell sizes of motor has the length of about 600mm, the sole mass and its quality of bearing which results in motor casing are all very large, mostly the shell of existing motor is to adopt certain thickness metal material to make, enclosure is also installed with cooling water pipe or has coolant flow channel, and mostly metal shell is that the mode of employing casting is shaping, its internal density is not very high, when not strengthening structure, the intensity of shell is difficult to meet instructions for use.
In addition, mostly cooling water pipe in existing motor housing or coolant flow channel are to be arranged in the middle part of the sidewall of motor housing, distance from the stators and rotators of motor internal is far, cooling effect is bad, radiating effect can be caused not reach requirement in the long-play process of high capacity motor, thus affect the normal use of motor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of motor for pure electric vehicle casing structure with spirality cooling water pipe, and casing structure is simple, and good heat dissipation effect, intensity is high, simple in production process operation, is applicable to the motor of Large Electric car.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of motor for pure electric vehicle casing structure with spirality cooling water pipe, comprise cooling water pipe and stainless steel stay pipe, the madial wall of described stainless steel stay pipe and the stator close contact of motor, described cooling water pipe is wrapped on the cylindrical sidewall of stainless steel stay pipe twist, the lateral surface of described stainless steel stay pipe is equipped with the metal master layer covered by cooling water pipe parcel, one end of described cooling water pipe is water inlet, and the other end is delivery port.
Supplement as to the one of technical scheme described in the utility model, the water inlet of described cooling water pipe and delivery port are positioned at the two ends of stainless steel stay pipe.
Further, described water inlet and delivery port are along the outside of stretching out at metal master layer that extends radially outwardly of stainless steel stay pipe.
Further, described water inlet and delivery port are with external screw thread or internal thread.
beneficial effect
The utility model relates to a kind of motor for pure electric vehicle casing structure with spirality cooling water pipe, and casing structure is simple, has the following advantages: (1) adds stainless steel stay pipe on original shell, substantially increases the bulk strength of shell; (3) stainless steel stay pipe directly contacts with inner motor stator, and shorten the distance between cooling water pipe and motor stator, be conducive to the transmission of heat, good heat dissipation effect, structure comparison is commonly used, and is applicable to the motor of most Large Electric car.
