A scroll heat dissipation structure of a scroll compressor

Abstract

The present scroll disk heat dissipation assembly of scroll compressors, its scroll disk comprises a disk body (1), and the heat dissipation assembly comprises several long stripped heat sinks (2)on the back of the disk body. These heat sinks are arranged in the same direction, and air ducts (3) are formed in between two adjacent heat sinks. Each heat sink is bended into a wave shape and the wave-shaped heat sink has several peaks (22) and several troughs (23) in the lengthwise direction. The locations of peaks and troughs in two adjacent heat sinks are aligned. In any heat sink, there is at least one peak located in a triangular zone (6), which is enclosed by the corresponding peak on the heat sink above and the two troughs on the two sides of that peak on that same heat sink.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to a scroll cooling structure of a scroll compressor. Background technique [0002] Scroll air compressors are widely used in industry, agriculture, transportation, civil pneumatic and other industries where compressed air is needed due to their high efficiency, low noise, small size, and benefits for energy saving and environmental protection. The main operating part of the scroll air compressor is the volute. The volute is only meshed and does not produce wear. Therefore, the service life is longer than that of the piston and screw compressors. It is an ideal power source for pneumatic machinery. In a scroll air compressor, the scroll as the main moving part is divided into a moving disk and a static disk, and a scroll piece is arranged inside the moving disk and the static disk. Usually, the moving disk and the static disk are combined to form a compression chamber. When the d...

[0003] For example, the Chinese invention patent application (application number: 201610122948.3) discloses an oil-free scroll air compressor, including a frame, a static disk, a moving disk, a bushing, a crankshaft, and a pin crank. The moving plate is installed in cooperation with the end face of the bushing and is located in the frame. The pin crank bearing at one end of the pin crank is installed on the frame, and the pin crank bearing at the other end of the pin crank is mounted on the bushing. The bushing is connected with at least three pins. Constrained by the crankshaft, the static disc and the movable disc driven by the crankshaft form a sealed cavity for continuous suction, compression and exhaust. The back of the rotor is provided with stepped rotor fins and a stepped shaft. The sleeve is installed on the rotor fin, and there is a gap between each bearing seat on the shaft sleeve and the rotor fin. The rotor dissipates heat through the rotor fin on the back. In addition to heat dissipation, the rotor fin also It can strengthen the strength of the moving plate in the transverse direction, but the moving plate lacks a strengthening structure in the longitudinal direction, so that the moving plate is prone to plane deformation
