Abstract

The utility model discloses a cooling end cover of a disc type motor, and the cooling end cover can perform liquid cooling on the permanent magnet disc type motor. The cooling end cover comprises a base body with a bearing chamber and a cover plate which can seal the bottom end of the base body, the bottom end surface of the base body is provided with a rotatory groove, after the cover plate seals the bottom end of the base body, the rotatory groove forms a closed cooling flow channel, and a side face of the base body is provided with a liquid inlet and a liquid outlet which are communicated with the head and the tail of the cooling flow channel. After adopting the structure of the cooling end cover of the disc type motor, heat generated on a motor stator core and a bearing is conducted to the base, and taken away by cooling liquid circulating in the cooling flow channel, the heat dissipation effects are very obvious, and the temperature of the motor can be well controlled. The cooling end cover of the disc type motor is simple in structure and easy to realize, heat dissipation of disc motors with different power can be realized only by reasonably designing a water route and the flow of cooling water, a relatively large heat dissipation area and relatively good heat dissipation effects can be obtained, high power density and high power of the motor are realized, and the cooling end cover has a wide range of application.

Description

The cooling end cap of disc type electric machine
Technical field
The utility model relates to a kind of end cap of motor, specifically a kind ofly can carry out to permanent magnet disc motor the cooling end cap of disc type electric machine of liquid cools.
Background technology
High power density disc type motor has that volume is little, lightweight characteristics, but because motor volume is little, the area of dissipation of motor is also little than conventional motors, and this has limited the power density of motor to a certain extent.Disc-type permanent magnet motor also is different from traditional radial flux motors, and traditional radial flux motors axial length is larger, can by increase the water cooling that water jacket is realized motor on the axial shell of motor, obtain cooling effect preferably; And the disc type electric machine of axial magnetic field is little due to axial length, and axially the area of dissipation of circumference is limited, adopts the poor effect of the liquid cools of axial circular side face.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can obtains larger area of dissipation and radiating effect preferably, realizes the cooling end cap of disc type electric machine of high power density and the high-power of motor.
In order to solve the problems of the technologies described above, the cooling end cap of disc type electric machine of the present utility model, comprise pedestal and the cover plate that can be sealed on the pedestal bottom with bearing chamber, the bottom end surface of pedestal is provided with rotating groove, make rotating groove form the coolant flow channel of sealing after the bottom end closure of cover plate with pedestal, have the inlet and the liquid outlet that communicate from beginning to end with coolant flow channel on the side of pedestal.
Described coolant flow channel has interior seal groove near the pedestal center, and coolant flow channel has the external seal groove near pedestal outer rim place, is mounted with sealing ring in external seal groove and interior seal groove.
Described annular stator core is riveted on base.
after adopting structure of the present utility model, because the bottom end surface of pedestal is provided with rotating groove, make rotating groove form the coolant flow channel of sealing after the bottom end closure of cover plate with pedestal, the heat that produces on motor stator core and bearing is transmitted on base, the interior cooling fluid that circulates of the runner that is cooled is taken away, radiating effect is fairly obvious, the temperature of motor can be well controlled, simultaneously because the face area of disc type electric machine is large, annular stator core is riveted on base, more be conducive to heat transfer, make its radiating effect better, the utility model is simple in structure, be easy to realize, disc type electric machine to different capacity only needs the flow of reasonable design water route and cooling water just can realize motor radiating, and can obtain larger area of dissipation and radiating effect preferably, realize high power density and the high-power of motor, have wide range of applications.

Fig. 1 is the understructure schematic diagram of the cooling end cap of the utility model disc type electric machine;
Fig. 2 is that the base A-A of the cooling end cap of the utility model disc type electric machine is to structural representation;
Fig. 3 is the integral installation structural representation of the cooling end cap of the utility model disc type electric machine.
Embodiment
Below in conjunction with the drawings and specific embodiments, the cooling end cap of disc type electric machine of the present utility model is described in further details.
as shown in the figure, the cooling end cap of disc type electric machine of the present utility model, comprise pedestal 2 and the cover plate 3 that can be sealed on pedestal 2 bottoms with bearing chamber 1, annular stator core is riveted on base 2, the bottom end surface of pedestal 2 is provided with rotating groove 4, cover plate 3 with the bottom end closure of pedestal 3 after with screw fastening and make rotating groove form the coolant flow channel 5 of sealing, have the inlet 6 and the liquid outlet 7 that communicate with coolant flow channel 5 head and the tail on the side of pedestal 2, can carry out cooling to bearing and the stator core of motor be connected with the cooling fluid of circulation in coolant flow channel 5 after, overflow in order to prevent cooling fluid, coolant flow channel 5 has interior seal groove 8 near the pedestal center, coolant flow channel 5 has external seal groove 9 near pedestal outer rim place, be mounted with sealing ring 10 in external seal groove 9 and interior seal groove 8.
