Abstract

The utility model discloses a vortex compressor, which comprises a shell, a crankshaft, a framework, a movable vortex disc, a static vortex disc, an air suction pipe, an air exhaust hole, an air exhaust check mechanism and an air exhaust pipe. The crankshaft is disposed in the shell, the framework is disposed on the crankshaft, the movable vortex disc is arranged at the top end of the crankshaft and located above the framework, the static vortex disc is arranged above the movable vortex disc and meshed with the movable vortex disc, the air suction pipe is disposed on the static vortex disc and communicated with a compression cavity formed by the movable vortex disc and the static vortex disc which are meshed, the air exhaust hole is arranged at the top of the static vortex disc and communicated with the center compression cavity, the air exhaust check mechanism is arranged above the static vortex disc and communicated with the air exhaust hole, the air exhaust pipe is disposed below the framework, both the air suction pipe and the air exhaust pipe extend out of the shell, and an air exhaust channel is disposed on the outer wall of the framework, and is a structure gradually expanding from top to bottom. The vortex compressor is simple in structure, only the groove shape of the air exhaust channel needs to be changed, the structure of the air exhaust channel reduces the flow rate of refrigerant flowing into the low-pressure cavity, is favorable for separation of oil and gas and reduces the level of noise, simultaneously, superheat degree of the refrigerant entering the low-pressure cavity is decreased, and accordingly, refrigeration cycle efficiency of the refrigerant is improved.

Description

Scroll compressor
Technical field
The utility model relates to the scroll compressor field, specifically is a kind of scroll compressor that can reduce the refrigerant degree of superheat.
Background technique
The stream of refrigerant in the scroll compressor in scroll compressor is to get in the compression chamber of moving vortex and fixed scroll engagement formation from sucking pipe earlier; Moving scroll revolves round the sun around bent axle under the driving of bent axle; Refrigerant obtains energy in moving scroll and fixed scroll formation many to compression chamber; Be discharged to hyperbaric chamber through the exhaust non-return mechanism then, the exhaust passage through frame gets into low pressure chamber again, discharges the entering condenser through outlet pipe at last and participates in heat exchange.When refrigerant flowed into low pressure chamber from hyperbaric chamber, flow velocity can increase suddenly, will produce the high-decibel noise; And the flow velocity height is unfavorable for effective separation of oil gas; The high pressure loss that produces of relative flow velocity is excessive, can cause the refrigerant degree of superheat to increase, thereby causes refrigeration cycle efficient to reduce.
The model utility content
The technical problem that the utility model will solve provides a kind of scroll compressor, and the refrigerant degree of superheat is too high in the existing scroll compressor of solution, influences the problem of the refrigerating efficiency of scroll compressor.
The technological scheme of the utility model is:
Scroll compressor; Comprise shell; Be arranged at bent axle in the shell, be arranged at frame on the bent axle, be arranged at the top of bent axle and be positioned at the top of frame moving scroll, be arranged at moving scroll top and with the intermeshing fixed scroll of moving scroll, be arranged on the fixed scroll and exhaust port that the sucking pipe that is communicated with compression chamber that moving scroll and fixed scroll engagement form, the top that is arranged at fixed scroll are communicated with the center compression chamber, be arranged at the exhaust non-return mechanism that is communicated with exhaust port above the fixed scroll and be arranged at the outlet pipe below the frame; Described sucking pipe and outlet pipe all reach outside the housing; The outer wall of described frame is provided with the exhaust passage, and the exhaust passage is the gradually expansion type structure from top to bottom.
Described exhaust passage be shaped to curve or high order curve moulding.
The advantage of the utility model: the exhaust passage of frame is a gradually expansion type along the refrigerant flow direction, so the flow velocity that its refrigerant flows through reduces gradually, so the noise that refrigerant produced when flowing through the exhaust passage can reduce, and flow velocity reduces the effective separation help oil gas; Relative flow velocity reduces, and separating pressure raises gradually, thereby the saturation temperature of refrigerant improves, and then the refrigerant temperature degree that is higher than saturation temperature also reduces, and the refrigerant degree of superheat that promptly gets into low pressure chamber reduces, and improves the refrigeration cycle efficient of refrigerant.

Embodiment
See Fig. 1; Scroll compressor; Comprise shell 1; Be arranged at bent axle 2 in the shell 1, be arranged at frame 3 on the bent axle 2, be arranged at the top of bent axle 2 and be positioned at the top of frame 3 moving scroll 4, be arranged at moving scroll 4 tops and with the intermeshing fixed scroll of moving scroll 45, be arranged on the fixed scroll 5 and exhaust port 8 that the sucking pipe 7 that is communicated with compression chamber 6 that moving scroll 4 and fixed scroll 5 engagements form, the top that is arranged at fixed scroll 5 are communicated with center compression chamber 6, be arranged at exhaust non-return mechanism 9 that fixed scroll 5 tops are communicated with exhaust port 8 and the outlet pipe 10 that is arranged at frame 3 belows, sucking pipe 7 and outlet pipe 10 all reach outside the housing 1;
See Fig. 2, Fig. 3, the outer wall of frame 3 is provided with exhaust passage 11, and exhaust passage 11 is the gradually expansion type structure from top to bottom, and the gradually expansion type structure is curve (see figure 2) or the moulding of high order curve (see figure 3).
See Fig. 1; The stream of refrigerant in scroll compressor is: 6 li of compression chambers that get into earlier moving vortex and fixed scroll engagement formation from sucking pipe 7; Around the bent axle revolution, refrigerant obtains energy in moving scroll and fixed scroll formation many to compression chamber to moving scroll, is discharged to hyperbaric chamber 12 through exhaust port 8, exhaust non-return mechanism 9 then under the driving of bent axle 2; Exhaust passage 11 through frame gets into low pressure chamber 13 again, discharges the entering condenser through outlet pipe 10 at last and participates in heat exchange.When refrigerant was flowed through exhaust passage 11, exhaust passage 11 was the gradually expansion type structure, had reduced the flow velocity that refrigerant flows through, and noise reduced when it flow through exhaust passage 11, and flow velocity reduces the oil gas help refrigerant and effectively separates; Relative flow velocity reduces, and separating pressure raises gradually, thereby the saturation temperature of refrigerant improves, and then the refrigerant temperature degree that is higher than saturation temperature also reduces, and the refrigerant degree of superheat that promptly gets into low pressure chamber reduces, and improves the refrigeration cycle efficient of refrigerant.
