A heat exchange device is provided. The heat exchange device comprises: a first heat exchanger (1) defining an upper end and a lower end; a second heat exchanger (2) defining an upper end connected to the upper end of the first heat exchanger (1) and a lower end spaced apart from the lower end of the first heat exchanger (1) in a longitudinal direction, such that a predetermined angle between the first heat exchanger (1) and the second heat exchanger (2) is ¸, where 0<¸<180°; and a wind guide member (3) disposed between the first heat exchanger (1) and the second heat exchanger (2) for guiding a wind toward the first heat exchanger (1) and the second heat exchanger (2) respectively.
