Problems solved by technology

Therefore, Haier, Gree and other companies use household rotary compressors in car parking air conditioners. The problems are: heavy iron casing, complicated finishing and welding equipment, large investment, which is not conducive to production, maintenance and disassembly, and vehicle vibration. Big
However, the main casing of the above-mentioned compressor is formed by crimping iron plates, and the compression mechanism is fixed into the main casing by shrink-fit

Embodiment 1

[0049] The frequency conversion electric rotary air conditioner compressor for new energy vehicles includes a housing 2 made of aluminum alloy, an upper end cover 33 made of aluminum alloy that is set on the upper end of the housing 2 and an upper end cover 33 that is located on the lower end of the housing 2. The lower end cover 34 made of aluminum alloy, the upper end cover 33 is fixed on the housing 2 by bolts, the lower end cover 34 is fixed on the housing 2 by bolts, and the seventh sealing ring 35 is arranged between the upper end cover 33 and the housing 2, An eighth sealing ring 36 is arranged between the lower end cover 34 and the housing 2 so that the inner cavity of the housing 2 forms an airtight airtight cavity.

[0050] like Figure 4 As shown, the upper end cover 33 is provided with a sealing cavity 40, the sealing cavity 40 is separated from the inner cavity of the housing 2 by a partition arranged in the upper end cover 33, and a terminal is provided in the se...

Embodiment 2

[0064] The structure of this embodiment is basically the same as the structure principle of Embodiment 1, the difference is that the compressor is a split compressor, and the controller is not set in the upper end cover 33 / housing 2 / lower end cover 34, that is, the controller located outside the compressor. Such as image 3 As shown, the first air inlet 1 is located on the top of the upper end cover 33 .

Embodiment 3

[0066] The structure of this embodiment is basically the same as the structure principle of Embodiment 1, the difference is that, as Figure 9 with Figure 10 As shown, the housing 2 is provided with a third outlet 30 communicating with the inner cavity of the housing 2 and a fourth inlet 31 coaxially arranged with the second air inlet 8, and the third outlet 30 is connected to the fourth inlet through a connecting pipe 32. 31 communicates, and one end of the connecting pipe 32 connected to the fourth inlet 31 is in sealing connection with the second air inlet 8 . The refrigerant gas enters the inner cavity of the housing 2 through the first air inlet 1 , and after cooling the motor, enters the suction part of the pump chamber 7 through the third outlet 30 , the connecting pipe 32 and the second air inlet 8 .

Abstract

The invention provides an electric variable frequency rotary type air compressor for a new energy vehicle, belonging to the technical field of compressors. By use of the electric variable frequency rotary type air compressor, the problems that an existing rotary type compressor has great mass so as to be disadvantageous to production and a vehicle-mounted scroll compressor needs high precision aresolved. The electric variable frequency rotary type air compressor comprises an aluminum casing, an upper end cover and a lower end cover; a motor is arranged in the casing; the upper end cover is provided with a first air inlet; a pump body assembly is arranged below the motor and is provided with a second air inlet and a first air outlet; the second air inlet is communicated with an inner cavity of the casing; the pump body assembly is provided with an exhaust drainage hood; the first air outlet is communicated with an inner cavity of the exhaust drainage hood; the exhaust drainage hood isprovided with a second air outlet; the casing is provided with a drainage pipe; and the inner end of the drainage pipe is connected with the second air outlet in a sealing manner. By using the aluminum casing, changing a process and replacing an aluminum scroll compressor with a rotary type compressor, the variable frequency electric rotary type air compressor provided by the invention has the advantages of convenience and quickness in assembly, convenience for maintenance, good stability, high reliability, simple manufacturing device and the like.

Description

technical field [0001] The invention belongs to the technical field of compressors, and relates to a vehicle air conditioner compressor, in particular to a new energy vehicle frequency conversion electric rotary air conditioner compressor. Background technique [0002] Compressor is a driven fluid machine that lifts low-pressure fluid to high-pressure fluid, and is the heart of the refrigeration system. The rotary compressors widely used in domestic air conditioners have a long history, and their characteristics are: simple structure, fully enclosed, welded assembly, stable operation, and high energy efficiency. Although the aluminum scroll compressors currently used in vehicle-mounted variable frequency DC electric air conditioners are light in weight, they require very high machining accuracy, and generally fail to meet the technical standards in China. Therefore, Haier, Gree and other companies use household rotary compressors in car parking air conditioners. The problem...
