Problems solved by technology

[0003] During the use of the existing compressor, the compressed high-pressure gas is directly discharged from the exhaust connection pipe on the exhaust end cover, and the high-pressure and high-speed pulsating airflow directly hits the exhaust end cover, causing the exhaust end cover to vibrate violently, resulting in The noise of the compressor on the exhaust side is abnormal, and it is easy to cause relatively large vibration of the exhaust pipeline

Embodiment Construction

[0038] see in conjunction Figure 1 to Figure 10 As shown, according to the embodiment of the present application, the scroll compressor includes an exhaust port 1 and an exhaust upper cover 2 covered at the exhaust port 1. The exhaust upper cover 2 includes a cavity, and an exhaust gas is arranged in the cavity. Noise-absorbing structure, the exhaust-muffling structure divides the cavity into a first exhaust chamber 3 and a second exhaust chamber 4, the first exhaust chamber 3 communicates with the exhaust port 1, and the second exhaust chamber 4 is located in the row The gas sound-absorbing structure is on the side away from the exhaust port 1 , and the gas discharged from the exhaust port 1 enters the second exhaust chamber 4 after passing through the first exhaust chamber 3 .

[0039] The first exhaust cavity 3 and the second exhaust cavity 4 can be formed by setting the exhaust noise reduction structure between the compressor exhaust port 1 and the exhaust upper cover 2, ...

Abstract

The invention provides a scroll compressor, an air conditioner and a vehicle. The scroll compressor comprises an exhausting port (1) and an exhausting upper cover (2) arranged at the position of the exhausting port (1) in a covering manner; the exhausting upper cover (2) comprises a cavity; an exhausting silencing structure is arranged in the cavity, and is used for partitioning the cavity into afirst exhausting cavity (3) and a second exhausting cavity (4) communicating with each other; the first exhausting cavity (3) communicates with the exhausting port (1); the second exhausting cavity (4) is located on one side, away from the exhausting port (1), of the exhausting silencing structure; and gas discharged out of the exhausting port (1) enters the second exhausting cavity (4) after passing through the first exhausting cavity (3). According to the scroll compressor, the exhausting pulse of the compressor can be reduced, and the compressor noise is lowered.

Description

technical field [0001] The application belongs to the technical field of air conditioning, and in particular relates to a scroll compressor, an air conditioner and a vehicle. Background technique [0002] With the gradual popularization of new energy vehicles, the requirements and specifications for spare parts for new energy vehicles are becoming more and more stringent. As a key component of the vehicle air-conditioning system, the performance characteristics of the compressor directly affect the application of the entire system, and vibration and noise can most affect the application experience. Reducing the vibration and noise of the compressor, as the focus of the R&D and application of the vehicle compressor, has become the consensus of the vehicle compressor manufacturers. The vibration noise of the compressor comes from motor noise, mechanical friction or impact, and suction and exhaust pulsation. The existing technology centers generally carry out targeted noise re...
