Abstract

In a secondary heat-transfer mechanism of a motor provided in the present invention, at least one heat-transfer member is disposed between a stator member and a base to which the stator member is attached, and the heat-transfer member is adjacent to the stator member and the base, so as to conduct heat energy to the heat-transfer member.

Claims

1. A secondary heat-transfer mechanism of a motor, comprising:

a base;

a stator member, directly or indirectly disposed on the base; and

at least one heat-transfer member, having a metallic body directly or indirectly attached to the base at one side and directly or indirectly attached to the stator member at the other side; and

a flow channel, disposed in the metallic body, with openings for external communication being formed at two ends of the metallic body.

2. The secondary heat-transfer mechanism of a motor according to claim 1, wherein the number of the heat-transfer member is two, and the two heat-transfer members are spaced from each other.

3. The secondary heat-transfer mechanism of a motor according to claim 1, wherein at least a part of the metallic body is sandwiched between the stator member and the base.

4. The secondary heat-transfer mechanism of a motor according to claim 3, wherein at least a part of the metallic body separates the stator member from the base.

5. The secondary heat-transfer mechanism of a motor according to claim 4, wherein two side surfaces of the metallic body are respectively attached to two side surfaces of the stator member.

6. The secondary heat-transfer mechanism of a motor according to claim 5, wherein the metallic body has a wing portion, which is the part of the metallic body that is sandwiched between the stator member and the base, one side of the wing portion being attached to one side of the stator member;

and a body portion, adjacent to the wing portion, one side of the body portion being attached to the other side of the stator member.

7. The secondary heat-transfer mechanism of a motor according to claim 6, wherein the thickness of the wing portion is less than the thickness of the body portion.

8. The secondary heat-transfer mechanism of a motor according to claim 6, wherein the flow channel is located in the body portion.

9. The secondary heat-transfer mechanism of a motor according to claim 1, wherein the metallic body is made of aluminum or an aluminum alloy through extrusion.

10. The secondary heat-transfer mechanism of a motor according to claim 1, wherein the metallic body extends to have a length, and the openings of the flow channel are located at two ends of a long axis of the metallic body.
