Technical problem to be solved in the utility model is to provide in addition at the above-mentioned state of the art that a kind of height is low, the air-conditioner of stable performance.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: air-conditioner, comprise housing and be located at the interior evaporimeter of housing, compressor and condenser, be provided with first blower fan of convection current in the accelerating chamber near aforesaid evaporimeter, be provided with second blower fan that quickens outside air convection near aforesaid condenser, it is characterized in that described condenser comprises first condensing unit and second condensing unit that is provided with at interval, be formed with the installation region between aforesaid first condensing unit and second condensing unit, described evaporimeter is the U-shaped that lies low substantially and is positioned at the rearward end of aforementioned installation region, and described compressor is positioned at the leading section of aforementioned installation region.

Further, described evaporimeter is arranged on the drip tray, and this drip tray then is located on the described housing.

Further, described drip tray middle part is connected with a vertical airduct, and described first blower fan is then over against this vertical airduct setting.Reasonable Arrangement reduces installing space, is beneficial to slimming and handles.

As preferably, described compressor is arranged at the inwall of described housing by a fixed mechanism, and described fixed mechanism comprises

Supporting seat has the fixing hole that passes through for bolt, is located at described compressor lower surface;

Bolt is fixed with nut by aforesaid fixing hole and top; And

Inserts is located at described inner walls and is connected and fixed with aforementioned bolt bottom.

Consider shockproof anti-jolting, described bolt is arranged with crash roll from top to bottom successively, antirattle spring reaches crash roll down, and aforesaid upward crash roll is positioned at the below of described supporting seat, and aforesaid crash roll down is positioned at the top of described inserts.

Compared with prior art, advantage of the present utility model is: adopt dual-row condenser, preferred arrangement in conjunction with U-shaped evaporimeter and compressor, evaporimeter and condenser, make whole height reduce greatly, be suitable for vehicle or yacht overhead type design needs, and reliable working performance is stable, installation is convenient, is beneficial to extension and produces.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, air-conditioner master in the present embodiment is with being applied in the car, certainly also can install on the boats and ships with yacht, specifically comprise housing 1 and be located at evaporimeter 3 in the housing 1, compressor 4 and condenser, housing 1 has base 12 and cover plate 11 to be assembled, housing 1 both sides are provided with air intake grid 24, be provided with first blower fan 31 of convection current in the accelerating chamber near evaporimeter 3, be provided with second blower fan 21 that quickens outside air convection near condenser, second blower fan, 21 air intake ports are provided with air inducing circle 22 and protecting wire net 23, condenser comprises first condensing unit 2 and the second condensing unit 2a that is provided with at interval, be formed with the installation region between first condensing unit 2 and the second condensing unit 2a, evaporimeter 3 is the U-shaped that lies low substantially and is positioned at the rearward end of installation region, and compressor 4 is positioned at the leading section of installation region, compressor 4 one sides also are provided with electric-controlled box 7, and this electric-controlled box 7 is made up of lid 71 and box body 72.
