Fixed scroll of scroll compressor

Abstract

Disclosed herein is a scroll compressor, and more particularly, a fixed scroll of the scroll compressor which can allow part of gaseous refrigerant to be smoothly introduced into a compression chamber while preventing introduction of the remaining gaseous refrigerant that is heated in the compressor. The fixed scroll includes a scroll body having an involuted wrap to define a compression chamber therein and provided, around a lower end thereof, with a mounting flange to be arranged on an upper surface of a main frame, and an interceptive suction portion configured to guide part of the gaseous refrigerant, that is directed upward along the main frame, into the compression chamber while preventing introduction of the remaining gaseous refrigerant that is circulated around the scroll body.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to a fixed scroll of the scroll compressor. The fixed scroll can make the gaseous refrigerant introduced into the compressor casing through the suction pipe directly into the compressor without being heated. cavity. Background technique [0002] figure 1 It is a longitudinal sectional view of important components of a traditional scroll compressor. figure 2 for figure 1 A perspective view of the fixed scroll in . [0003] Such as figure 1 and figure 2 The arrows shown in represent the flow direction of the sucked gaseous refrigerant. [0004] Such as figure 1 and figure 2 As shown in , the traditional scroll compressor includes: a casing 100, which defines a sealed space and is provided with a suction pipe 101 and a discharge pipe 102; a compression assembly 200, which is arranged on the upper part of the casing 100 and is suitable for compressing gaseous refrigerant and a ...
