Vibration and noise reduction device of vehicle electric air conditioner compressor

Abstract

The invention belongs to the technical field of air conditioner compressors, and discloses a vibration and noise reduction device for a vehicle electric air conditioner compressor, which comprises a base, a fixing column is mounted at the top of the base, a fixing plate is connected to the top end of the fixing column, a compressor body is mounted at the top of the fixing plate, and reinforcing rods are hinged to the two ends of the fixing plate, a cavity groove is formed in the position, close to the lower portion of the fixing column, of the top of the base, a second spring is fixed to the bottom end of the interior of the cavity groove, and the end, extending into the cavity groove, of the fixing column is connected with the second spring. Through cooperation of the structures such as the fixing plate, the fixing column, the second spring, the reinforcing rods and the first spring, vibration of the fixing plate can be effectively reduced, then buffering and energy dissipation can be conducted on a compressor body, the vibration amplitude of the compressor body is greatly reduced, violent shaking of the compressor body is avoided, meanwhile, noise is further reduced, and the using effect of the device is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning compressors, and in particular relates to a vibration and noise reduction device for a vehicle electric air-conditioning compressor. Background technique [0002] The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit. The air conditioner compressor is generally installed in the outdoor unit. The air conditioner compressor extracts the refrigerant from the low pressure area and sends it to the high pressure area for cooling and condensation. The heat sink emits heat into the air, the refrigerant also changes from gaseous to liquid, and the pressure rises. The working circuit of the air conditioner compressor is divided into an evaporation area (low pressure area) and a condensation area (high pressure area). The indoor unit of the air conditioner and the outdoor unit Machines belong to the low-pressure or high-pr...
