The invention relates to the technical field of automobile noise, in particular to an automobile noise reduction structure, an automobile air conditioning system and an automobile. The compressor is connected with an air conditioner pipe, an expansion silencer is arranged on the air conditioner pipe of the compressor, the expansion silencer is provided with an expansion chamber, the ratio of the diameter of the expansion chamber to the diameter of the air conditioner pipe is 5-8, and the ratio of the distance from the expansion chamber to the compressor to the diameter of the air conditioner pipe is smaller than 10. The expansion silencer reduces the internal pulsation of the compressor while reducing the dynamic pulsation transmitted to the pipeline by the compressor. According to the electric compressor, in-vehicle vibration noise caused by the electric compressor is reduced, the size of the silencer is reduced, an additional fixing support is not needed, and the cost is reduced while the noise reduction effect is guaranteed.

    本发明涉及汽车噪声技术领域,尤其涉及一种汽车降噪结构、车用空调系统及汽车。压缩机连接空调管,在压缩机的所述空调管上设置有扩张消声器,所述扩张消声器具有扩张室,所述扩张室的直径与空调管的直径比值为5~8,所述扩张室到压缩机的距离与空调管的直径比值小于10,扩张消声器在降低压缩机向管路传递动态脉动的同时降低压缩机的内部脉动。通过本发明降低电动压缩机引起的车内振动噪声,并减小了消声器尺寸,无需额外的固定支架,在保证降噪效果的同时降低了成本。
