Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor cooling, and particularly relates to a motor with a motor base fixing structure and a cooler. BACKGROUND

[0002] A motor needs to use a cooler for heat dissipation when running. The cooler is fixed on a motor base. The cooler blows cooled cold air into the motor. Therefore, the connection part between the motor and the cooler should be sealed by using a certain sealing method to prevent gas from being blown out from the gap. A traditional scheme arranges a sealing gasket on the motor base for sealing.

[0003] With the long-time running of the motor, the sealing gasket is gradually thinned and even damaged due to the weight of the cooler and the vibration of the motor during running. This causes air leakage at the connection part, thereby affecting the cooling effect of the cooler and the normal running of the motor.

[0004] Therefore, it is necessary to develop a motor with a motor base fixing structure and a cooler to solve the above problems. TECHNICAL SOLUTION

[0005] The motor with the motor base fixing structure and the cooler can prolong the service life of the motor.

[0006] To achieve the above object, the motor with the motor base fixing structure and the cooler is provided as follows.

[0007] The motor base comprises an outer shell, a cavity formed in the inner part of the outer shell, and an air exchange port penetrating through the outer shell and communicating with the cavity.

[0008] The motor is arranged in the cavity.

[0009] The sealing assembly comprises a gasket and a sealing element arranged on one side of the gasket. The gasket is laid on the surface of the outer shell and surrounds the air exchange port. The height of the sealing element is greater than that of the gasket.

[0010] The cooler is fixedly installed on the motor base and corresponds to the air exchange port. The cooler covers the gasket and the sealing element. The sealing element fills the gap between the cooler and the motor base.

[0011] Further, the gasket is in the form of a rectangular frame. The sealing element is laid on the outer side or the inner side of the gasket.

[0012] Further, the sealing element is also laid above the gasket.

[0013] Further, the side of the sealing element that is attached to the motor base is coated with an adhesive.

[0014] Further, the gasket has a fixing hole penetrating through its upper and lower surfaces, a counterbore is reserved, the shell has a mounting hole formed by being recessed inward from the surface, the mounting hole corresponds to the fixing hole, and a bolt or screw penetrates through the fixing hole and extends into the mounting hole.

[0015] Further, the gasket is arranged in segments outside the air exchange opening, and the sealing member surrounds the segmented gasket one by one.

[0016] Further, the shell is a rectangular body, a top of which forms a plane, and the plane is provided with the air exchange opening.

[0017] Compared with the prior art, the motor with the cooler and the base fixing structure has the advantages that the gasket and the sealing member higher than the gasket are arranged outside the air exchange opening, the gasket with a certain thickness limits the minimum thickness of the sealing gasket after being compressed, so that the sealing gasket will not be damaged and lose the sealing effect due to long-time compression, the service life of the sealing ring is prolonged, and the cooling effect of the cooler is ensured.
