[0035] Combination Figures 1 to 4As shown, the utility model provides a kind of air pipe type air conditioner, including heat exchange shell 100, heat exchanger 200, fan assembly 300 and cover shell.Heat exchange shell 100 includes mounting portion 110 and shell plate portion, and shell plate portion is equipped with air outlet, and mounting portion 110 includes the bottom plate 111 and mounting plate 112 of bending connection, and the bottom plate 111 and mounting plate 112 are integrally formed.Heat exchanger 200 is arranged at the inner side of bottom plate 111.Fan assembly 300 is arranged at the outer side of mounting plate 112.Cover shell covers the outer periphery of fan assembly 300 and is connected with mounting plate 112, and cover shell is equipped with air inlet, and the thickness of cover shell is less than the thickness of mounting portion 110.

[0036] Optionally, the inside of heat exchange shell 100 is defined as heat exchange cavity, and heat exchanger 200 is arranged in heat exchange cavity.Specifically, heat exchange shell 100 includes mounting portion 110 and shell plate portion (not shown in the figure).Mounting portion 110 and shell plate portion jointly limit heat exchange cavity.Mounting portion 110 is thickened to improve structural strength.Mounting portion 110 includes mounting plate 112 and bottom plate 111, and they are bendingly connected and integrally formed.When air pipe type air conditioner is installed horizontally, bottom plate 111 is below heat exchanger 200 and is located at the inner side of mounting plate 112.
