Vortex compressor for large displacement vehicle

Abstract

The great displacement vehicular vortex compressor includes shell, movable disc, static disc and crankshaft. The shell is divided into a high pressure cavity and a low pressure cavity with the static disc possessing exhaust hole to communicate the high pressure cavity and the low pressure cavity, the low pressure cavity has air inlet port and the high pressure cavity has exhaust port. The movable disc, the static disc and the main part of the crankshaft are inside the shell, the movable disc is installed on one end of the crankshaft, the crankshaft has the other end extended beyond the shell and connected with the driving wheel, and the movable disc is inserted inside the static disc. The present invention features the movable disc and the static disc with profile height of 34-60 mm and fundamental circle radius of 3.6-7 mm.

Description

technical field [0001] The invention relates to a scroll compressor for a vehicle, in particular to a scroll compressor for a large displacement vehicle. Background technique [0002] At present, the scroll compressor is a kind of air-conditioning compressor that has developed very rapidly in recent years. It has a high speed, can work normally under the condition of less oil, has a long service life, and is convenient and simple to maintain. , compared with large displacement reciprocating compressors, the largest base circle radius of the existing single scroll compressor is only 3 mm, and the largest profile height is below 33 mm, which can basically meet the needs of small vehicles. requirements, and for buses and similar occasions that have high requirements for refrigeration and heat, the existing single scroll compressor cannot meet the requirements at all. Therefore, the applicant once proposed to use two scroll compressors to be installed in parallel This method so...

[0002] At present, the scroll compressor is a kind of air-conditioning compressor that has developed very rapidly in recent years. It has a high speed, can work normally under the condition of less oil, has a long service life, and is convenient and simple to maintain. , compared with large displacement reciprocating compressors, the largest base circle radius of the existing single scroll compressor is only 3 mm, and the largest profile height is below 33 mm, which can basically meet the needs of small vehicles. requirements, and for buses and similar occasions that have high requirements for refrigeration and heat, the existing single scroll compressor cannot meet the requirements at all. Therefore, the applicant once proposed to use two scroll compressors to be installed in parallel This method solves the problem of using scroll compressors on large vehicles to a certain extent, but this method still has complex structures, large installation space, and failure rates in the long run. It is twice as much as a single compressor, and the cost is relatively high, so the development of a large-displacement scroll compressor is a top priority

[0003] As we all know, the maximum radius of the base circle of the existing scroll compressor is 3.5 mm, and the profile height is generally below 33 mm, which limits the expansion of the displacement of the compressor.
