Title:
AIR-COOLED COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2022/105209
Kind Code:
A1
Abstract:
An air-cooled compressor, comprising a rotor (1), an impeller (2) and at least one main air passage. The main air passage is arranged surrounding a stator (41), an outlet of the tail end of the main air passage is connected to a high pressure air cavity by means of the impeller (2), and an air source of the main air passage is used for air cooling. The impeller (2) is a closed impeller, and comprises a rear cover (201), blades (202), a sleeve body (203) and a front cover (204), wherein the front cover (204) covers the blades (202) and is in a circular truncated cone shape; an air intake surface of the front cover (204) is a curved surface having a smooth transition along the ridge line contours of the blades (202); a back air surface is provided with grooves matching end parts of the blades (202); the end parts of the blades corresponding to the grooves are embedded in the grooves and are in tight fit connection therewith; and the front cover (204) is made of a carbon fiber composite material. The air-cooled compressor has a simple structure and high reliability, without the need for installing an air cooling fan on a shaft; and a closed impeller is used, such that the air-cooled compressor has little flow resistance, high efficiency, a light structure, and high strength.
