Description

Compressor

Technical Field

The utility model relates to the technical field of compressors, in particular to a compressor.

Background

For the existing totally-enclosed high-back-pressure compressor, the refrigerant compressed by the pump body is discharged from the exhaust port of the pump body and then passes through the motor to reach the exhaust pipe of the compressor. In this process, it is desirable that the refrigerant absorbs some of the heat emitted by the motor, and acts to cool the motor. Obviously, to cool the pump body, the temperature of the fluid discharged from the pump body needs to be lower than the temperature of the motor, and the final exhaust temperature of the fluid after absorbing heat is higher than the fluid temperature before absorbing heat. Since the fluid temperature prior to heat absorption cannot be accurately measured, the art generally places a limit on the final exhaust temperature after heat absorption.

With more and more heating application scenes, the related products need to raise the final exhaust temperature after absorbing heat as much as possible. This means that the fluid temperature before heat absorption also needs to be increased. However, this is likely to occur when the temperature difference between the fluid temperature before heat absorption and the temperature of the motor becomes small, resulting in failure to cool the motor, and even when the fluid temperature is higher than the motor temperature, which in turn heats the motor. And the excessively high temperature can cause accelerated degradation of the motor insulating material, shorten the overall service life of the compressor and influence the reliability of the compressor.

It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the utility model and thus may include information that does not form the prior art that is already known to those of ordinary skill in the art.

As shown in fig. 1 and 2, an embodiment of the present utility model discloses a compressor. The compressor comprises a motor 11, a pump body assembly 12 and a vortex tube 13. The pump body assembly 12 is fixedly connected with the vortex tube 13; for example, the flange bolts can be used for fixing connection, and the connection and fixing modes are not limited in the application. The pump body assembly 12 comprises a crankshaft, the crankshaft is connected with the motor 11, and the motor 11 drives the pump body assembly 12 to rotate through the crankshaft to provide power for the pump body assembly 12.

Referring to fig. 6 to 8, in this embodiment the vortex tube 13 also has a cold end outlet 15 for discharging cold fluid and a hot end outlet 16 for discharging hot fluid. The cold end outlet 15 communicates with a cavity between the pump body assembly 12 and the motor 11. The cold fluid is discharged into the cavity through the cold end outlet 15.

The vortex tube 13 is characterized by a split flow entering from the inlet 14, one from the hot side outlet 16 and one from the cold side outlet 15. Wherein the temperature of the hot fluid is greater than the temperature of the inlet 14 fluid and the temperature of the inlet 14 fluid is greater than the temperature of the cold fluid. Illustratively, the temperature of the fluid at the inlet 14 may be 100 ℃, the temperature of the cold fluid may be 80 ℃, and the temperature of the hot fluid may be 120 ℃, for example. The present application is not limited thereto.

In this embodiment, the hot end outlet 16 of the vortex tube 13 is in communication with the outside of the compressor, and the hot fluid is discharged to the outside of the compressor through the hot end outlet 16. For example, the hot fluid may be discharged via a discharge pipe 22 of the compressor, or to a condenser of the air conditioning system, for example.

In an alternative embodiment, referring to fig. 2, the compressor further comprises a second connecting line 21. The hot side outlet 16 is connected to the compressor discharge pipe 22 via a second connecting line 21, so that the hot fluid is discharged via the second connecting line 21 and the discharge pipe 22.
