Abstract

A motor includes a cooling enclosure. The cooling enclosure includes a cover body, an inner fan, and an outer fan. A first cooling cavity, a second cooling cavity, and an isolating cavity between the first cooling cavity and the second cooling cavity are formed in the cover body. A plurality of first and second cooling pipes are respectively disposed in the first and second cooling cavity; both being in communication with the isolating cavity and the outside. The cover body includes a first surface and an opposite second surface. The inner fan is disposed on the first surface. Sides of the inner fan are respectively in communication with the first and second cooling cavities. The inner fan is configured to provide circulating power for internal circulating air. The outer fan is in communication with the isolating cavity. The cooling enclosure and the motor can realize relatively high cooling efficiency.

Claims (42)

1. A cooling enclosure, comprising:

a cover body, the cover body internally including

a first cooling cavity, a plurality of first cooling pipes being disposed in the first cooling cavity,

a second cooling cavity, a plurality of second cooling pipes being disposed in the second cooling cavity, and

an isolating cavity, located between the first cooling cavity and the second cooling cavity, the first cooling pipes and the second cooling pipes both being in communication with the isolating cavity and outside the cooling enclosure, the cover body further including

a first surface, and

a second surface, the second surface being opposite to the first surface and configured to be mounted on a housing of a motor;

an inner fan, disposed on the first surface, one side of the inner fan being in communication with the first cooling cavity and another side of the inner fan being in communication with the second cooling cavity, the inner fan being configured to provide circulating power for internal circulating air; and

an outer fan, disposed on the first surface, located on the isolating cavity and in communication with the isolating cavity, wherein

the second surface of the cooling enclosure includes a first air vent in communication with the first cooling cavity and the housing of the motor and a second air vent in communication with the second cooling cavity and the housing of the motor,

the isolating cavity is not in communication with the housing of the motor, and

a width of the isolating cavity along a direction parallel with the first cooling pipes and the second cooling pipes is constant.

2. The cooling enclosure of claim 1 , further comprising:

an inner air path guide air cylinder, located on the first surface, the inner fan being located on the second cooling cavity and the inner air path guide air cylinder being configured to communicate the first cooling cavity with the inner fan.

3. The cooling enclosure of claim 2 , wherein the cover body further internally includes:

a first partition plate; and

a second partition plate, the first partition plate and the second partition plate being spaced to form the isolating cavity.

4. The cooling enclosure of claim 3 , wherein the cover body further comprises:

a first enclosure net, the first cooling pipes being connected between the first enclosure net and the first partition plate; and

a second enclosure net, disposed opposite to the first enclosure net, the second cooling pipes being connected between the second enclosure net and the second partition plate.

5. The cooling enclosure of claim 2 , wherein the inner fan and the outer fan are centrifugal fans.

6. A motor, comprising the cooling enclosure of claim 2 , the cooling enclosure being connected to the motor.

7. The cooling enclosure of claim 2 , further comprising:

a housing, wherein the cooling enclosure is disposed on the housing and the second surface faces the housing.

8. The cooling enclosure of claim 1 , wherein the cover body further internally includes:

a first partition plate; and

a second partition plate, the first partition plate and the second partition plate being spaced to form the isolating cavity.

9. The cooling enclosure of claim 8 , wherein the cover body further comprises:

a first enclosure net, the first cooling pipes being connected between the first enclosure net and the first partition plate; and

a second enclosure net, disposed opposite to the first enclosure net, the second cooling pipes being connected between the second enclosure net and the second partition plate.

10. A motor, comprising the cooling enclosure of claim 9 , the cooling enclosure being connected to the motor.

11. A motor, comprising the cooling enclosure of claim 8 , the cooling enclosure being connected to the motor.

12. The cooling enclosure of claim 8 , further comprising:

a housing, wherein the cooling enclosure is disposed on the housing and the second surface faces the housing.

13. The cooling enclosure of claim 1 , wherein the inner fan and the outer fan are centrifugal fans.

14. A motor, comprising the cooling enclosure of claim 13 , the cooling enclosure being connected to the motor.

15. A motor, comprising the cooling enclosure of claim 1 , the cooling enclosure being connected to the motor.

16. The motor of claim 15 , further comprising:

a housing, wherein the cooling enclosure is disposed on the housing and the second surface faces the housing.

17. The motor of claim 16 , wherein the second surface is provided with a first air vent and a second air vent, the first air vent being in communication with the first cooling cavity and the housing, and the second air vent being in communication with the second cooling cavity and the housing.

18. The motor of claim 17 , wherein the motor includes a driving end and a non-driving end, the non-driving end being opposite to the driving end, the first cooling cavity being located on the driving end, and the second cooling cavity being located on the non-driving end.

19. The motor of claim 16 , wherein a length of the cover body is equal to or slightly greater than a length of the housing.
