Abstract

The utility model relates to a driving motor cooling water sleeve. The driving motor cooling water sleeve resolves the problems that an existing driving motor cooling water sleeve is limited in heat exchange area and poor in cooling effect. The driving motor cooling water sleeve comprises shell body water pipelines, water pipeline inlets and water pipeline outlets which are all arranged on a shell body, wherein two sides of the shell body are provided with end caps, a plurality of the shell body water pipelines are provided and arranged in parallel along the axial direction of the shell body, the end caps at the two sides are respectively provided with a plurality of flow guide bended grooves which enable two adjacent shell body eater pipelines to be communicated, and the flow guide bended grooves of the end caps at the two sides are arranged in a corresponding and staggered mode. The driving motor cooling water sleeve is simple in structure, good in heat exchange effect, low in machining and manufacturing cost, and capable of effectively lowering the weight of a motor and achieving the purposes of energy conservation and consumption reduction.

Description

The drive motors cooling jacket

Technical field

The utility model relates to a kind of drive motors, specifically a kind of cooling jacket of drive motors.

Background technology

Modern electrical machine receives the restriction of electromagnetic load, arrangement space, generally has the energy density height, and volume is little, and rotating speed is high, the characteristics that caloric value is big.Drive motors as one of pure electric automobile core technology not only will have big starting torque, broad constant power speed range (being higher weak magnetic energy power) also will be arranged, and in the rotating speed of motor scope, have higher efficient.The pure electric automobile drive motors is big or when moving under the operating mode when continuing climbing etc., motor will produce great amount of heat in load.If the heat of motor internal can not be is in time taken out of by refrigerant on every side; Then can shorten the life-span of motor; Reduce operational efficiency, even cause permanent magnetic material irreversible demagnetization to occur, and the most general cooling jacket is merely simple spiral water jacket (referring to Fig. 1) at present because of overheated; Its heat exchange area is limited, and cooling-down effect still remains to be improved.

Summary of the invention

To the objective of the invention is in order solving the problems of the technologies described above, a kind of simple in structure, good effect of heat exchange to be provided, the processing and manufacturing cost is low, can effectively reduce motor weight, the cooling jacket of energy-saving and cost-reducing drive motors.

Technical scheme comprises housing water route and water route import and the water route outlet of being located on the housing; End cap is equipped with in said housing both sides; Said housing water route has many; To being arranged in parallel, said two side ends covers and all has a plurality of curved grooves of water conservancy diversion that adjacent two housing water routes are communicated with along housing shaft, and the corresponding stagger arrangement of the curved groove of the water conservancy diversion that said two side ends covers is arranged.

The cross section in said housing water route is circular, round rectangle or fan-shaped.

The curved groove of water conservancy diversion through the both sides end cap is communicated with two adjacent housing water routes, and the stagger arrangement of the curved groove of the water conservancy diversion that said two side ends covers is arranged and is meant: if on the A, B, three parallel housing water routes of C; The curved groove of water conservancy diversion on one side end cap is communicated with A with B; Then the curved groove of the water conservancy diversion on the opposite side end cap then is communicated with B with C, and this connected mode can all be communicated with several housing water routes; And on housing, form continuous " S " water route; Can increase the heat exchange area of water jacket so greatly, improve heat exchange efficiency, help reducing the flow resistance in the water route.And the import of the more convenient cooling water channel of this structure and the location arrangements of outlet can be arranged on the end cap of the same side according to the import and export of concrete needs with cooling water channel, perhaps also can be arranged in two side ends and cover, and are convenient to install.Owing to increased the heat exchange area of cooling water channel, also can reduce the weight of motor to greatest extent, the load of minimizing equipment or vehicle.

Embodiment

Below in conjunction with accompanying drawing present embodiment is further explained:

With reference to Fig. 1-8; Motor is made up of with rear end cap 3 housing 1 and front end housing 2; Said housing 1 is provided with many along housing 1 axially parallel layout housing water route 6; Have a plurality of curved grooves 7 of water conservancy diversion that adjacent two housing water routes 6 are communicated with on said front end housing 2 and the rear end cap 3, the curved groove 7 of the water conservancy diversion on the said front end housing 2 is bent groove 7 stagger arrangement with the water conservancy diversion on the rear end cap and is arranged.Also be provided with water route import 4 and water route outlet 5 on the said housing 1, water route import 4 exports 5 in the same side of housing 1 with the water route in the present embodiment, also can be provided with as required and be separately positioned on both sides.

Operation principle; Referring to Fig. 1, cooling water import 4 by water flows into, and a warp wherein housing water route 6 gets into the curved groove 7 of a water conservancy diversion in the front end housings 5; And then via getting into the curved groove 7 of a water conservancy diversion in the rear end cap 3 with adjacent housing water route 6, last housing water route; By that analogy, the last item housing water route 6 of flowing through at last exports 5 more by water and discharges, and accomplishes the process that cools for motor.

Claims

1. drive motors cooling jacket; Comprise housing water route and water route import and the water route outlet be located on the housing, end cap is equipped with in said housing both sides, it is characterized in that; Said housing water route has many; To being arranged in parallel, said two side ends covers and all has a plurality of curved grooves of water conservancy diversion that adjacent two housing water routes are communicated with along housing shaft, and the corresponding stagger arrangement of the curved groove of the water conservancy diversion that said two side ends covers is arranged.

2. drive motors cooling jacket as claimed in claim 1 is characterized in that, the cross section in said housing water route is circular, round rectangle or fan-shaped.
