Mixed type vortex plate heat dissipation structure of oil-free scroll compressor

Abstract

The invention provides a mixed type vortex plate heat dissipation structure of an oil-free scroll compressor. The structure comprises a cooling disc and a plurality of V-shaped cooling fins, Z-shapedcooling fins and one-shaped cooling fins which are fixed on the heat dissipation disc, wherein the plurality of V-shaped cooling fins are arranged at equal intervals in the vertical center line of thecooling disc, the plurality of Z-shaped cooling fins are arranged in the horizontal center line of the cooling disc, and first convection passages are formed between every two adjacent V-shaped cooling fins; one end of each Z-shaped cooling fin is in streamline type cutting at the horizontal center line to form middle convection passages, and second convection passages are formed between every two adjacent Z-shaped cooling fins; the plurality of one-shape cooling fins are arranged at the two ends of the horizontal center line and are symmetrically distributed in a center mode, and third convection passages are formed between every two adjacent one-shape cooling fins; and the one-shape cooling fins close to the center side of the cooling disc is in a streamline type and is bent towards themiddle convection passages. According to the mixed type vortex plate heat dissipation structure of the oil-free scroll compressor, the air flow can be effectively guided, and the dynamic and static vortex plates of the oil-free scroll compressor can be cooled.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a hybrid scroll cooling structure of an oil-free scroll compressor. Background technique [0002] With the rapid development of society, energy and environmental issues have become the two most important issues affecting the future survival of human beings. Scroll compressors are widely used due to their low noise, small size, high efficiency, energy saving and environmental protection. As a branch of the scroll compressor and the latest research hotspot, the oil-free scroll compressor works basically the same as the ordinary scroll compressor, through the meshing between the movable scroll and the fixed scroll of its main moving parts And each other forms a compression chamber that can be continuously changed. When the crankshaft drives the movable scroll to move eccentrically along a certain circular track, the compression chamber formed by the movable scroll blade and the...

Problems solved by technology

[0003] For the existing oil-free scroll compressor, there is no lubricating oil in the compression cavity of the static and dynamic scrolls to achieve sealing and lubrication, so a lot of heat will be generated in the process of compressing air, so it is necessary to cool down the dynamic and static scrolls, otherwise the static and dynamic scrolls will Due to the technical problem that the disk will be deformed due to high temperature and uneven force, the invention provides a hybrid scroll heat dissipation structure for an oil-free scroll compressor
