Embodiment
The preferred embodiment of the utility model described with reference to the accompanying drawings.It should be understood by those skilled in the art that
It is that these embodiments are used only for explaining the technical principle of the utility model, it is not intended that limit the protection of the utility model
Scope.For example, although each component in attached drawing is drawn with special ratios, but what this proportionate relationship was merely exemplary,
Those skilled in the art as needed can make adjustment it, to adapt to specific application scenario.
As shown in Figure 1, in the present embodiment, air-conditioner outdoor unit includes housing 1 and 2 and of wind turbine being arranged in housing 1
Heat exchanger 3.Specifically, housing 1 includes rear casing 11, sets gradually wind turbine 2 along the direction away from rear casing 11 in housing 1 and changes
Hot device 3；Wherein, after air-conditioner outdoor unit is installed on wall, rear casing 11 is close to the side of wall.Set on rear casing 11
There is air intake grid 111, when wind turbine 2 is run, be blowed to heat exchanger 3, i.e., air enters in housing 1 from air intake grid 111, Ran Houcong
Heat exchanger 3 flows out housing 1.
With reference to Fig. 2, Fig. 2 is the air current flow direction schematic diagram in the air-conditioner outdoor unit of the utility model.Such as Fig. 2 institutes
Show, the air-conditioner outdoor unit of the utility model, since heat exchanger 3 is located at the front of wind turbine 2, (air-conditioner outdoor unit is installed on wall
After upper, the side where wall be rear, and user oriented side is front), so, during the operation of wind turbine 2, air from into
Air grid 111 (direction in Fig. 2 shown in arrow) enters housing 1, is then flowed out from heat exchanger 3 (direction in Fig. 2 shown in arrow).
That is, relative to the structure of existing air-conditioner outdoor unit, the structure of the air-conditioner outdoor unit of the utility model can make wind
The heat exchanging device 3 in a manner of blowing of machine 2 carries out enhanced heat exchange, so as to improve the heat exchange efficiency of heat exchanger 3.
Referring back to Fig. 1, in the present embodiment, housing 1 further includes front cover shell 12, and heat exchanger 3 is disposed in proximity to front cover shell
12 position.Specifically, since air is blowed to heat exchanger 3 by wind turbine 2, and the heat sink of heat exchanger 3 is larger to the resistance of air-flow,
So that the wind speed blown out from heat exchanger 3 is relatively low, air supplying distance is near, therefore, in order not to influence heat transfer effect, in front cover shell 12 with changing
Hot 3 corresponding position of device sets opening, so that heat exchanger 3 is exposed in environment close to the side of front cover shell 12.Consequently, it is possible to change
The front of hot device 3 does not have obstacle, further increases heat exchange efficiency.
With continued reference to Fig. 1, in the present embodiment, wind turbine 2 includes motor 21 and fan 22, and motor 21 is used for driving fan 22
Rotate.Head cover 13 and partition plate 14 are additionally provided with housing 1, partition plate 14 will be divided into first chamber and second chamber inside housing 1, its
In, first chamber is used to set wind turbine 2 and heat exchanger 3.Compressor 4 is additionally provided with housing 1, compressor 4 is located at second chamber.
It will be clear that it (is respectively first chamber and the second chamber that the space in housing 1 is divided into two chambers by partition plate 14 from Fig. 2
Room), wind turbine 2 and heat exchanger 3 are located at first chamber, in Fig. 2, fan 22 are illustrate only in first chamber, the rear of fan 22 (is pressed
According to the direction in Fig. 2) it is heat exchanger 3.Compressor 4 is located at second chamber.
As described above, after the air-conditioner outdoor unit of the utility model is installed on wall, along the direction away from wall successively
For rear casing 11, wind turbine 2, heat exchanger 3, front cover shell 12.Wind turbine 2 operation in the case of, dry to heat exchanger 3, i.e., air from
Air inlet grill 111 enters in housing 1, is then flowed out from heat exchanger 3.Since the position that front cover shell 12 corresponds to heat exchanger 3 is an opening,
Therefore will not heat exchanging device 3 outlet air formed stop.Due to wind turbine 2, (i.e. wind turbine 2 is directly towards heat exchanger 3 in a manner of blowing
It is blowed) the progress enhanced heat exchange of heat exchanging device 3, so as to improve the heat exchange efficiency of heat exchanger 3.
In a preferred embodiment, one layer of hydrophobic coating is coated on the heat sink of heat exchanger 3.Preferably, should
Hydrophobic coating is graphene.Due to being coated with grapheme material on the heat sink of heat exchanger 3, and existing air-conditioner outdoor unit changes
Usually hydrophilic layer is all coated on hot device.Compared with existing air-conditioner outdoor unit, the heat transfer efficiency of the heat exchanger 3 of the utility model is more
Height, and due to the hydrophobicity of graphene, in heating operations, can quickly roll off the condensed water on 3 surface of radiator.This
Outside, since the frost layer formed during air conditioner frosting is thicker, the heat transfer of heat sink is relatively slowly transmitted to whole frost layer, but is changing
The root of spreader surface frost layer, that is, frost layer when white, is the position that can form moisture film earliest, in the work of hydrophobic layer after formation moisture film
Just it is easy to be peeled off with lower frost layer.Therefore, using the utility model air-conditioner outdoor unit structure, wind turbine 2 is straight by air
Connect and blow to heat exchanger 3, make frost layer be easier to be blown off, in the outer space for directly falling to heat exchanger 3.
In conclusion since the characteristic of graphene hydrophobic coating, heat exchanger of outdoor machine of air conditioner 3 are hot right with surrounding air
Stream mode, is changed into blowing (since the wind turbine 2 of the utility model is located at the rear of heat exchanger 3, the wind that wind turbine 2 is blown out from former air draught
Directly blow to heat exchanger 3).The air velocity of fin surface is very fast during blowing, and the droplet formed on heat sink is easy to by wind
Take away, the situation that droplet forms frost is greatly decreased.And air conditioner run defrost when, the heat exchanger heat sink of outside and
Frost layer is contiguously square into moisture film, and frost layer is just easy to be stripped, and the frost layer of bulk will be blown off by being blown by wind one, be lowered significantly
The defrosting time of air conditioner.
So far, have been combined preferred embodiment shown in the drawings and describe the technical solution of the utility model, still, this
Field technology personnel are it is easily understood that the scope of protection of the utility model is expressly not limited to these embodiments.
Without departing from the utility model principle on the premise of, those skilled in the art can make correlation technique feature equivalent change
Or replace, the technical solution after these are changed or replace it is fallen within the scope of protection of the utility model.
