Abstract

Provided are a compressor electric motor cooling structure, and a compressor and a refrigeration system having the compressor electric motor cooling structure. The compressor electric motor cooling structure comprises a housing (1), an electric motor (2) and a guide structure (4), wherein the electric motor (2) is provided inside the housing (1), the electric motor (2) is provided with a flow path (3), and the guide structure (4) is used for guiding a refrigerant to the flow path (3). The compressor electric motor cooling structure guides the refrigerant to the flow path (3) by means of the arrangement of the guide structure (4), so that the refrigerant can pass through the interior of the electric motor (2) more effectively. In combination with the flow path (3) provided in the electric motor (2), the contact area between the refrigerant and the electric motor (2) can be increased, and the cooling effect on the electric motor can be improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a compressor motor cooling structure, a compressor and a refrigeration system. Background technique [0002] Screw compressors can be divided into two types: open type and semi-hermetic type according to the connection mode between the compressor and the motor. The open screw compressor is connected to the motor through a coupling, and a shaft seal needs to be installed on the rotor shaft of the compressor to prevent leakage of refrigerant and lubricating oil; the motor is an open air-cooled motor. The semi-hermetic screw compressor has the motor built into the compressor, the motor and the compressor are integrated, and the compressor shell is connected by a flange, which can effectively prevent the leakage of refrigerant and lubricating oil, and use refrigerant to cool the motor to ensure reliable cooling of the motor ; The motor is a semi-closed motor. [0003] Since t...
