The invention relates to a heat exchanging device, which comprises a case body, a heat exchanger, fins, and an air guiding component, wherein the heat exchanger is arranged in the case body, and forms an included angle alpha with a backing plate of the case body; the heat exchanger is provided with a first collecting pipe, a second collecting pipe and a plurality of flat pipes; both ends of each flat pipe are respectively connected with the first collecting pipe and the second collecting pipe so as to communicate the first collecting pipe with the second collecting pipe; and the flat pipes are separated along the axial direction of the first collecting pipe and the second collecting pipe; the fins are arranged between adjacent flat pipes; and the air guiding component is used for making the air stream in an area between the heat exchanger and the backing plate pass through the heat exchanger from one part of the area at least vertically and/or approximate vertically. By using the heat exchanging device of the embodiment of the invention, the air guiding component can make the air stream pass through heat exchanger from the lower part of the area between the heat exchanger and the backing plate vertically or approximate vertically, and thereby, the collision friction between the air stream and the fins of the heat exchanger can be reduced, and noise is reduced. |
