Abstract

The utility model provides an effective vortex compressor oil separating structure of an automotive air conditioner, comprising a high pressure cavity consisting of a vortex compressor fixed volute disc and a back cover, wherein the high pressure cavity is divided into the high pressure cavity, a separating cavity and an oil storing cavity, the high pressure cavity is communicated with the separating cavity through a first hole, the separating cavity is communicated with the oil storing cavity through a second hole, the oil storing cavity is communicated with an annular groove at the back end of the fixed volute disc through a bottom groove, the annular groove is communicated with an air inlet through a capillary hole, a separating core is arranged in the separating cavity in an interference fit, the end of the separating cavity arranged at the upper part of the separating core is an air outlet, the central axis of the first hole is tangent to the central line of an annular space consisting of the wall of the separating cavity and the wall of the separating core. By using the vortex compressor oil separating structure of the utility model, the oil circulating quantity of the air conditioner of the vortex compressor is below 0.4%, thereby greatly improving the heat exchanging efficiency of the air conditioner and strengthening the lubricating effect of the compressor.

Description

Car air conditioner scroll compressor oil separating structure efficiently

Technical field

The utility model relates to a kind of oil separating structure of scroll compressor efficiently, relates in particular to a kind of car air conditioner scroll compressor oil separating structure.

Background technique

Scroll compressor is a kind of novel positive displacement compressor, compare with traditional compressor, its have simple in structure, noise is low, volume is little, in light weight, running steadily, the efficient advantages of higher, therefore more and more widely be used to automotive air-conditioning system.In actual use, compressor itself will cause inner body aggravation wearing and tearing because oil return is bad, influences the life-span; To take certain space owing to refrigeration oil enters systemic circulation again, and, have a strong impact on the heat transfer rate of refrigerant, and make refrigerating capacity reduce attached to pipeline and vaporizer inwall.In other words, the high efficiency that consider a compressor also should take into full account the oil content of refrigerant in the system.

Summary of the invention

The purpose of this utility model provides a kind of structure that improves the heat exchange efficiency of air-conditioning system and strengthen the lubrication effect of compressor self.

In order to achieve the above object, the technical solution of the utility model has provided a kind of scroll compressor of car air conditioner efficiently oil separating structure, it is characterized in that: comprise the hyperbaric chamber that the hyperbaric chamber be made up of scroll compressor static vortex disk and bonnet is isolated into, disengagement chamber and shoe cream room, hyperbaric chamber communicates with disengagement chamber by first hole, disengagement chamber communicates with shoe cream room by second hole, shoe cream room communicates by the circular groove of bottom stria with the static vortex disk ear end face, circular groove communicates with inlet hole by pore, interference is equipped with a separation core in disengagement chamber, it is exhaust port that disengagement chamber is positioned at the end of separating the core top, and the central axis in first hole is tangent with the center line of the annular space that the wall of disengagement chamber and the wall that separates core are formed.

Further, have first separating vessel on the surface of described separation core.

On the wall of the chamber of described disengagement chamber, have second separating vessel.

Described first separating vessel or described second separating vessel are at least 3.

The oily circulating load of air-conditioning system of scroll compressor that the structure that the utility model provides has been installed is below 0.4%, improved the heat exchange efficiency of air-conditioning system greatly and strengthened the lubrication effect of compressor self.

Description of drawings

A kind of scroll compressor of car air conditioner efficiently oil separating structure that Fig. 1 provides for the utility model;

Fig. 2 is for separating the core schematic representation;

Fig. 3 A is the disengagement chamber schematic representation;

Fig. 3 B is that K among Fig. 3 A is to enlarged view.

Embodiment

Specify the utility model below in conjunction with embodiment.

Embodiment

Shown in Fig. 1 to Fig. 3 B, the utility model provides a kind of scroll compressor of car air conditioner efficiently oil separating structure, comprise the hyperbaric chamber A that the hyperbaric chamber be made up of scroll compressor static vortex disk and bonnet is isolated into, disengagement chamber B and shoe cream room C, hyperbaric chamber A communicates with disengagement chamber B by first hole 2, disengagement chamber B communicates with shoe cream room C by second hole 4, shoe cream room C communicates with the circular groove 5 of static vortex disk ear end face by the bottom stria, circular groove 5 communicates with inlet hole 7 by pore 1, interference is equipped with a separation core 3 in disengagement chamber B, disengagement chamber B be positioned at the end of separating core 3 tops be exhaust port 8, the first holes 2 central axis and disengagement chamber B wall and to separate the center line of annular space of wall composition of core 3 tangent.

Have first separating vessel 9 on the surface of separating core 3.On the wall of the chamber of disengagement chamber B, have second separating vessel 10.The sectional shape of first separating vessel 9 and second separating vessel 10 comprises: rectangle groove, circular trough, elliptical slot and any special-shaped groove, quantity is at least 3.The purpose that first separating vessel 9 and second separating vessel 10 are set is to increase separating effect.

When refrigeration oil and after the mixture of compression refrigerant (hereinafter to be referred as mixture) has entered hyperbaric chamber A chamber from static vortex disk base apertures 6, enter disengagement chamber B from second hole 2, because the above-mentioned special construction of disengagement chamber B, mixture will be around separating core 3 surface rotations, again because the adhesive ability difference of refrigeration oil and refrigerant in the mixture, impel refrigeration oil to enter shoe cream room C toward dirty from second hole 4 along disengagement chamber B chamber wall, enter static vortex disk end face circular groove 5 through shoe cream room C foot passage, because shoe cream room C pressure is higher than inlet hole pressure, make refrigeration oil rise to the top and enter inlet hole by pore 1 again from the circular groove bottom, so form an oil circulation, and refrigerant will enter exhaust port 8 discharge compressors through the center hole that separates core 3.
