Abstract

The invention provides a cover plate, a compressor and an air conditioner. A plurality of cooling channels are formed in the cover plate. A cooling inlet communicating with the cooling channels is formed in the first end face of the cover plate. A distance exists between the cooling inlet and the center line of the cover plate. A plurality of cooling outlets are evenly formed in the second end face of the cover plate and are in one-to-one correspondence with the cooling channels. The lengths of the cooling channels are increased gradually in the direction from the cooling inlet to the center of the first end face of the cover plate. By the adoption of the technical scheme, the problem that in the prior art, the cooling requirement of a motor cannot be met is solved.

Description

technical field [0001] The invention relates to the technical field of compressor cooling, in particular to a cover plate, a compressor and an air conditioner. Background technique [0002] At present, the existing low-temperature semi-hermetic screw compressor includes a motor and a screw connected to the motor for driving, and the motor is horizontally arranged in the compressor housing. During the working process of the compressor, the motor adopts an independent cooling structure to cool it, generally direct liquid spray cooling or spiral spray liquid cooling. Wherein, the direct liquid spray cooling is to set a cooling port corresponding to the motor on the side wall of the compressor housing, and spray liquid to the motor from the cooling port. Spiral liquid spray cooling requires a spiral cooling pipeline. [0003] In the prior art, when direct liquid spray cooling is used, the motor flows from the top of the motor to the axial direction of the motor and along the s...
