Technical Field

Background

Scroll compressors are widely used as a type of compressor commonly used in the compressor field, such as automotive air conditioning scroll compressors. The working principle of the scroll compressor is as follows: a plurality of compression chambers are formed by an orbiting scroll having a wrap and a fixed scroll engaged with each other. The crankshaft drives the movable scroll to make eccentric rotation translation relatively to the fixed scroll, so that each compression cavity moves towards the center side and gradually reduces the volume. Thereby effecting compression of the fluid within the chamber.

When the scroll compressor normally works, a certain amount of lubricating oil needs to be filled to ensure the cooling lubrication of parts such as the mechanical friction and the bearing of the compressor and the oil sealing between the scroll teeth and at the sealing part. However, when the compressor is operated, the lubricant oil inside the compressor enters the refrigerant pipeline of the air conditioning system along with the refrigerant. This portion of the oil entering the refrigerant lines typically accumulates in the relatively low heat exchanger lines. This can lead to a series of adverse effects, such as: 1. the lubricating oil occupies the inner space of the heat exchanger pipeline, so that the heat exchange area of the refrigerant is reduced, the heat exchange quantity of the heat exchanger is influenced, and the refrigerating capacity of the air conditioning system is reduced; 2. the lubricating oil is deposited at the bottom of the heat exchanger and cannot return to the compressor, so that poor lubrication of a friction pair of the compressor is easily caused, the power consumption is increased, and the compressor can be even damaged in severe cases. Therefore, the scroll compressor needs to be designed with an oil return structure, and the oil return structure in the existing scroll compressor is not reasonable enough in design.
