The air of shell 10 successively can carry out heat exchange by back row's heat exchanger 340 and middle row's heat exchanger 320.Back row's heat exchanger 340 wraps
Back row's heat exchange fin 341 and back row's heat exchanger tube are included, multiple back row heat exchange fins 341 are arranged in multiple parallel arrangement of back row heat exchange
Guan Shang.
It should be noted that compared with front rows of heat exchanger 330 and heel row heat exchanger 310, the wind on middle 320 surface of row's heat exchanger
Speed is higher, and then by windward side setting back row's heat exchanger 340 in middle row's heat exchanger 320, air can be made to first pass through back
Heat exchanger 320 is arranged in flow direction after arranging heat exchanger 340, on the one hand improves the heat exchange area of heat exchanger group 30 Yu air, it is another
Aspect is but also the air velocity on middle 320 surface of row's heat exchanger is thereby reduced by being decayed after the row's of back heat exchanger 340
The wind speed on middle 320 surface of row's heat exchanger, so that the heat exchange of middle row's heat exchanger 320 is more abundant.
Further, for above-mentioned back arranges heat exchanger 340, in order to reduce the occupancy to space in shell 10, the back
The length direction arrangement for arranging multiple back row's heat exchanger tube edge back row's heat exchange fin 341 of heat exchanger 340 is in single setting.Such one
Come, the width of back row's heat exchange fin 341 can be reduced, to reduce the thickness of back row's heat exchanger, and then in order to compared with small shell
Back row's heat exchanger 340 is installed in 10.
Further, the range of the caliber D4 of above-mentioned back row heat exchanger tube are as follows: 6.35 millimeters≤D4≤8 millimeter；For the ease of
The installation of back row's heat exchanger 340 in back row's heat exchanger 340, the quantity which arranges heat exchanger tube is even number.Above-mentioned back arranges heat exchange wing
The finned length of piece 341 is 72 millimeters to 84 millimeters, wherein settable back arranges the number of heat exchanger tube on back row's heat exchange fin 341
Amount preferably 4 to 6.
Further, referring to Fig. 7, in another embodiment of this wall-hanging air conditioner indoor unit 1, for heat exchanger group 30
Speech, middle row's heat exchanger 320 can be with back row's heat exchangers 340 in being wholely set, in this way, compared with a upper embodiment, middle row

Fin width for 9 millimeters to 26 millimeters, front-seat heat exchange fin 331 is 9 millimeters to 26 millimeters.
It is understood that due to the small volume of shell 10, and the thickness of middle row's heat exchanger 320 is larger, in order to be conducive to
Middle row's heat exchanger 320 is in the arrangement of shell 10, and in the present embodiment, the shape of centering row's heat exchanger 320 has made adjustment: middle row is changed
The windward side of hot device 320 is easy to abut interference with shell 10, and then the length of the windward side of heat exchanger 320 is arranged in diminution.
In order to guarantee that heat transfer effect, middle row's heat exchanger tube are evenly arranged on middle row's heat exchanger 320, windward side in middle row's heat exchanger 320
Length be less than the length of leeward side, in this way, to be less than other two rows of near the quantity of middle row's heat exchanger tube of a row of windward side
The quantity of middle row's heat exchanger tube.
Further, for middle row's heat exchanger 320, a total of tubes of middle row's heat exchanger tube is usually even number, in order to
The connection between heat exchanger tube is arranged in adjacent two, since the length of the windward side of middle row's heat exchanger 320 is smaller, may make near meeting
The quantity of middle row's heat exchanger tube of one row of wind side is even number, and arranging the quantity of heat exchanger tube in other two rows is odd number.
