Abstract
The invention provides a window type fin which comprises a plurality of window sheets arrayed from one end to the other end of the window type fin. At least one part of the plurality of window sheets from one end to the other end of the window type fin adopt a structure different from that of the rest part of window sheets, so that the water drainage performance of the window sheets between the preset position (between one end to the other end of the window type fin) and the other end of the window type fin is improved. By adopting the above structure, the window type fin in the invention can drain water more easily than the conventional window type fin. The water drainage effect of the window type fin is good, accumulated water on the surface of a heat exchanger is less, and the heat resistance is small, so that the heat exchanging performance of the window type fin in the invention is also better than that of the conventional window type fin. The invention provides the window type fin for the heat exchanger and the heat exchanger with the window type fin.
