Embodiment 1

[0014] figure 1 The scroll compressor shown includes a fixed scroll 1 and a movable scroll 2, and the scroll wall of the fixed scroll 1 is meshed with the scroll wall of the movable scroll 2; when they work, they move relative to each other to form A closed compression cavity with variable volume, and an exhaust passage 3 is provided in the middle of the fixed scroll 1 . A transitional chamfer is provided between the round hole of the exhaust channel 3 of the fixed scroll 1 and the outer plane of the inner cavity port of the fixed scroll 1, such as figure 2 , image 3 As shown; the transition chamfer of this embodiment along the axial depth of the round hole of the exhaust passage 3 is H, H=1.5 mm, and the angle of the chamfer is B=45°; this structure can make the scroll compressor Compression efficiency is improved.

Embodiment 2

[0016] The transitional chamfering along the axial depth of the round hole of the exhaust passage 3 is H=0.5mm, and the angle of the chamfering is B=30°; other features are the same as those in Embodiment 1.

Embodiment 3

[0018] The transitional chamfering along the axial depth of the round hole of the exhaust channel 3 is H=1.5 mm, and the angle of the chamfering is B=60°; other features are the same as those in Embodiment 1.

Abstract

The invention discloses a scroll compressor, relating to the technical field of manufacturing of fluid machinery. The scroll compressor comprises a static scroll plate provided with an exhaust passage, wherein a transition chamfer angle is arranged between a circular hole of the exhaust passage of the static scroll plate and the outer plane of the port of the inner cavity of the static scroll plate. Compared with the prior art, the compression efficiency of the scroll compressor provided by the invention can be enhanced.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a scroll compressor including a fixed scroll disk. Background technique [0002] The scroll compressor compresses the fluid medium through the relative meshing motion of the movable and fixed scrolls. The fixed scroll and the movable scroll mesh with each other to form a moving closed chamber. The movable scroll wraps around the fixed scroll. When doing planar rotation, the volume of the closed chamber formed by the static and movable scrolls changes from large to small, and moves toward the center of the static scroll. The vortex center of the static scroll is equipped with an exhaust channel. After compression The gaseous medium is discharged from the exhaust channel. Since the scroll wall of the movable and static scrolls has a certain thickness, the scroll wall of the movable scroll will cover and open the inner port of the exhaust passage during the process of compl...
