Double-turbine electric-vortex-type automotive air-conditioner compressor

Abstract

The invention discloses a double-turbine electric-vortex-type automotive air-conditioner compressor. The double-turbine electric-vortex-type automotive air-conditioner compressor comprises a motor and two vortex pump heads respectively arranged at two ends of the motor. The motor is arranged in a compressor shell, and comprises a stator, a rotor and a motor rotating shaft from outside to inside. Each vortex pump head comprises a static disc base, a static disc and a dynamic disc. The spiral directions of teeth in the two vertex pump heads at the two ends of the motor are opposite. The double-turbine electric-vortex-type automotive air-conditioner compressor has the advantages that a group of opposite vertex pump heads is adopted as a compression body, the vertex pump heads work correspondingly, vibration caused during eccentric operation of a single pump is avoided, and the compressor works smoothly, so that the range of working speed of the compressor is wide, the single variety of compressors has wider application range, and cost for enterprise production can be reduced; only pumps with 1-2 types of displacement are needed to be produced, and production of plenty of pump blanks is not needed, so that labor intensity of warehouses is reduced, and convenience and rapidness in management are achieved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a twin-turbine electric scroll type vehicle air-conditioning compressor. Background technique [0002] With the development of the automobile industry and the improvement of the people's material civilization level, people have higher and higher requirements for the comfort, reliability and safety of automobiles, and automobile air conditioners are indispensable hardware facilities for automobiles. Air conditioning devices have become a measure of One of the signs of whether the car is fully functional. There is no doubt that China will become the world's largest automobile market, and the continuous increase in automobile production will surely promote the continuous expansion of the demand for automobile air-conditioning compressors. With the development of high-tech technology and the limited limitation of non-renewable resources, new energy electric vehicles have become the domina...

Problems solved by technology

[0003] With the development of DC scroll compressors for air conditioners in electric vehicles, the scope of their applications has gradually expanded, such as the modification of 24V truck air conditioners, the improvement of air conditioners in minibuses and buses, etc., but due to the constraints of domestic equipment and material factors, the It is very difficult to process scroll parts with large displacement. At present, the only way to make up for it is to increase the number of compressors.

In addition, because the existing compressor structure is a single pump head, when the movable scroll is in eccentric operation, a certain vibration will be generated on the plane perpendicular to the motor shaft, so there is a limit when designing the compressor speed (0 ---6000), making the cooling capacity of a single compressor relatively limited
