2 . The dryer or the washer dryer according to claim 1 , wherein a length direction of the condensing structure is arranged vertically to a front panel or a side plate of the washer dryer; an air inlet of the condensing structure is located in an upper part, an air outlet of the condensing structure is located in a lower part, and the air inlet and the air outlet are communicated with a drum through an air duct respectively; and one of the gas inlet and the gas outlet is provided with fans, and the other one is communicated with the atmosphere.

3 . The dryer or the washer dryer according to claim 1 , wherein the heat exchanger comprises a plurality of fins which are superposed up; two opposite side edges of each fin are bent upwards to form a ventilating air path in coordination with an upper fin, and adjacent fins are arranged in a mode of vertical-horizontal alternating so as to form transversal air paths and longitudinal air paths independent from each other; the longitudinal air path is vertically arranged to correspond to the air inlet and the air outlet; the transversal air path is horizontally arranged to correspond to the gas inlet and the gas outlet; downwards convex pins are arranged on lower surfaces of two upwards bent side edges of the fin, and downwards concave slots are arranged in upper surfaces of other two sides edges, and pins of the fins are inserted into slots on lower fins so as to connect an upper and a lower adjacent fins.

4 . The dryer or the washer dryer according to claim 1 , wherein a plurality of downward profiled grooves are provided in parallel are provided in a direction vertical to the air path formed by the fin and an upper fin, and an air path formed with a lower fin is divided into a plurality of parallel air paths by the profiled grooves; downward profiled grooves are provided on the fin in an air inlet and an air outlet in the front and rear of air paths formed between the fin and an upper fin, and the profiled grooves form the slots; and a profiled depth on both ends of the profiled groove is greater than a profiled depth in middle of the profiled groove, so that a downward bulge is formed, so as to form the pin.

5 . The dryer or the washer dryer according to claim 3 , wherein four side edges of the fin are bent outwards to form turn-ups; turn-ups of adjoining upper and lower fins are overlapped, turn-ups at the slots are overlapped and fitted closely on turn-ups, which are bent upwards first before bent outwards, on a lower fin; and the fins are plastic fins.

6 . The dryer or the washer dryer according to claim 1 , wherein frame plates are arranged on an upper side, a lower side, a left side, a right side, a front side and a rear side of the heat exchanger, and the frame is of an enclosure structure formed by connecting the frame plates arranged on the sides of the heat exchanger; wherein through holes cooperated with air paths of an internal heat exchanger are arranged in two groups of frame plates opposite to the transversal air path and longitudinal air path, and the other group of opposite frame plate are flat plates; and the through holes are rectangular through holes arranged transversally and longitudinally.

7 . The dryer or the washer dryer according to claim 6 , wherein a connection part is arranged at the junction of each frame plate on the frame, and adjacent frame plates are connected through connection parts; each connection part is of a buckle structure; a plurality of parallel grooves are arranged on internal surfaces of two groups of frame plates with the through holes, and the grooves correspond to the closely fitted turn-ups, and the closely fitted turn-ups are inserted into the grooves of internal surfaces of corresponding frame plates; and a plurality of sheet-shaped bulges vertical to frame plates are arranged on adjacent edges of the two groups of frame plates with the through holes; a shape of the sheet-shaped bulges is identical with that of a space between corresponding adjacent turn-ups at the pin, and the sheet-shaped bulges are respectively inserted into the space between corresponding adjacent turn-ups at the pins.

8 . The dryer or the washer dryer according to claim 1 , wherein an upper cover plate is arranged at the hot air inlets of the heat exchanger, the upper cover plate has a inclined top surface, the upper cover plate forms a chamber with the heat exchanger, and the air inlet of the condensing structure is formed on the chamber at one end where the upper cover plate is inclined highly and away from the heat exchanger; a lower cover plate is arranged at the hot air outlets of the heat exchanger, one side of the lower cover plate is the air outlet of the condensing structure; and the upper cover plate and the lower cover plate are connected with flat frame plates.

9 . The dryer or the washer dryer according to claim 1 , wherein a filtering structure is arranged between the air inlet of the condensing structure and the hot air inlets of the heat exchanger; the filtering structure is arranged between the air inlet of the condensing structure and the hot air inlet of the heat exchanger in a pushable-pullable manner; the filtering structure is arranged in the chamber, the filtering structure is slidably connected with sidewalls of the chamber, one end of the filtering structure protrudes out of the chamber, and when one end of the filtering structure is located in the innermost part of the chamber, the other end of the filtering structure is located outside the chamber and hermetically connected with an opening of the chamber through which the filter penetrates; and sliding chutes/sliding blocks are arranged on two side edges of the filtering structure, and sliding blocks/sliding chutes are arranged on corresponding sidewalls of the chamber, and the sliding chutes/sliding blocks are matched with the sliding blocks/sliding chutes so as to form sliding connection.
