Abstract
The invention discloses a cooling water jacket for a motor of an electrical vehicle, which comprises a double-layer structure. An outer-circle shell layer (1) and an inner-circle layer (2) of a water cooling cavity are welded into one part. The outer-circle shell layer (1) is provided with a cooling water pipe (3). The inner-circle layer (2) of the water cooling cavity is provided with a spiral trapezoidal radiating rib (4), which forms a spiral water cavity (5) with the outer-circle shell layer (1). The invention has the advantages that by adopting the double-layer structure proposal, the outer-circle shell layer and the inner-circle layer of the water cooling cavity are welded together into one part, which not only plays a good role of leak proofing and water sealing but also leads a motor base to have the good strength; the inner-circle layer of the water cooling cavity is designed into the spiral trapezoidal radiating rib to form a spiral hollow cavity together with the outer-circle shell layer, which greatly increases radiating area, enhances radiating efficiency and increases heat transfer capacity. Therefore, the heat produced by the motor can be taken away completely, the output power of the motor is increased by 150 percent and the motor efficiency reaches 93 percent.
Description
Technical field
The present invention relates to a kind of cooling jacket, particularly cooling jacket of electric car motor.
Background technology
The various losses that produce during the motor operation are transformed into heat, make each parts heating of motor, and temperature raises.The limit value that its temperature raises directly influences the useful life of motor.In the water-cooled machine, the support waterway adopts smooth water-cooled cavity mostly, or adopts snakelike groove waterway at home.Adopt the motor of smooth waterway for support, because area of dissipation is little, support intensity is low, makes the motor power output only improve 40%.Adopt the motor of snakelike groove waterway for support, though can solve the support strength problem preferably, but its area of dissipation is still less, make the heat of motor generation in service can not obtain fully transmitting, limit the raising of motor radiating efficient, therefore limited the raising of motor power output.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, and a kind of cooling jacket of electric car motor that makes water as coolant is provided, and volume is small and exquisite, can improve the power density of motor, significantly improves cooling effect.
Purpose of the present invention is achieved through the following technical solutions: cooling jacket of electric car motor, it comprises double-decker, outer ring shell and water-cooled cavity inner layer are welded into an integral body, the outer ring shell is provided with cooling water pipe, water-cooled cavity inner layer is provided with cocke-stair shape radiating ribs, forms a spirality water cavity with the outer ring shell.
By top narration as can be seen, the present invention has the following advantages: adopt the double-decker scheme, outer ring shell and water-cooled cavity inner layer are welded into a whole, and can well reach the effect of leakproof water shutoff, can make the support of band cavity that good intensity is arranged again.Be designed to cocke-stair shape radiating ribs on the water-cooled cavity inner layer, form a spirality cavity with the outer ring shell, area of dissipation is increased considerably, thereby raising radiating efficiency, increase the heat exchange capacity, the heat that motor is produced is taken away fully, thereby makes the motor power output improve 150%, and electric efficiency reaches 93%.

Fig. 2 is a water-cooled cavity inner layer structure chart of the present invention
Among the figure, 1-outer ring shell, 2-water-cooled cavity inner layer, 3-cooling water pipe, 4-radiating ribs, 5-spirality water cavity, 6-rotor, 7-stator, 8-front end housing, 9-rear end cap, 10-velocity transducer, 11-outgoing cable
Embodiment
The present invention will be further described below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, cooling jacket of electric car motor, it comprises double-decker, outer ring shell 1 is welded into an integral body with water-cooled cavity inner layer 2, outer ring shell 1 is provided with cooling water pipe 3, water-cooled cavity inner layer is provided with cocke-stair shape radiating ribs 4, forms a spirality water cavity 5 with the outer ring shell.Rotor 6, stator 7 are set in cooling jacket, front end housing 8 and rear end cap 9 are set respectively, be connected with velocity transducer 10 and outgoing cable 11 on the rear end cap 9 in two terminations of outer ring shell 1.
