PROBLEM TO BE SOLVED: To provide a vibration isolating support structure of a heat exchanger for an automobile air conditioner reducing the noise radiation in a cabin by reducing the propagation of the vibration from the heat exchanger to a car body frame. SOLUTION: This vibration isolating support structure of the heat exchanger for the automobile air conditioner is so formed that an air ventilation surface of the heat exchanger is vertically disposed and the top and the bottom of the heat exchanger are fitted to the car body frame. The heat exchanger is fitted to the car body frame at upper one support portion and the lower two support portions via vibration isolating materials respectively, stoppers are fitted to the upper portion of the heat exchanger and one car body frame, and stopper brackets surrounding the stoppers at prescribed interval held therefrom are fitted to the other car body frame. The three-point support of the heat exchanger can reduce the natural frequency of the heat exchanger vibration isolation system so as to drastically reduce the propagation of the vibration of the heat exchanger to the car body, and the stoppers can prevent the excessive displacement of the heat exchanger so as to prevent the damage of connecting devices.
