PROBLEM TO BE SOLVED: To suppress abnormal noise (whistling noise) generated by wind made to flow along the upwind side surface of a heat exchanger in the width direction of the heat exchanger without increasing the size. SOLUTION: The upwind side surface of the heat exchanger 8 includes: a first wind guide plate 15 guiding wind made to change the orientation by wind guide resistance and to flow along the upwind side surface of the heat exchanger 8 to the heat exchanger width direction out of wind hitting the heat exchanger 8 to the direction vertical to the heat exchanger 8; and a second wind guide plate 16 guiding wind made to flow over the first wind guide plate 15 and to further flow along the upwind side surface of the heat exchanger 8 in the heat exchanger width direction in the direction vertical to the heat exchanger 8.
