[0002] When the car air conditioner is in use, the refrigerant will flow in the air-conditioning pipes. In order to cooperate with other components in the car, the air-conditioning pipes have many bending angles. Therefore, when the refrigerant flows in the air-conditioning pipes, due to the change in pressure, noise will be generated and transmitted to the car compartment, affecting the comfort of the driver and passengers in the car.
