Fig. 2 is the air current flow direction schematic diagram in the air-conditioner outdoor unit of the present invention.
Embodiment
The preferred embodiment of the present invention described with reference to the accompanying drawings.It will be apparent to a skilled person that this
A little embodiments are used only for explaining the technical principle of the present invention, it is not intended that limit the scope of the invention.Although for example,
Each component in accompanying drawing is drawn with special ratios, but what this proportionate relationship was merely exemplary, those skilled in the art
It can be made adjustment as needed, to adapt to specific application scenario.
As shown in figure 1, in the present embodiment, air-conditioner outdoor unit includes housing 1 and the and of blower fan 2 being arranged in housing 1
Heat exchanger 3.Specifically, housing 1 includes setting gradually blower fan 2 along the direction away from rear casing 11 in rear casing 11, housing 1 and changed
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 blower fan 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.
Reference picture 2, Fig. 2 is the air current flow direction schematic diagram in the air-conditioner outdoor unit of the present invention.As shown in Fig. 2 this
The air-conditioner outdoor unit of invention, due to heat exchanger 3 be located at blower fan 2 front (after air-conditioner outdoor unit is installed on wall, wall
The side at place is rear, and user oriented side is front), so, when blower fan 2 is run, air is from air intake 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).Namely
Say, relative to the structure of existing air-conditioner outdoor unit, the structure of air-conditioner outdoor unit of the invention can make blower fan 2 with blowing
Mode heat exchanging device 3 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 also includes front cover shell 12, and heat exchanger 3 is disposed in proximity to front cover shell
12 position.Specifically, because air is blowed to heat exchanger 3 by blower fan 2, and the fin 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 to not influence heat transfer effect, in front cover shell 12 with changing
The corresponding position of hot device 3 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, blower fan 2 includes motor 21 and fan 22, and motor 21 is used to drive fan 22
Rotate.Top cover 13 and dividing plate 14 are additionally provided with housing 1, dividing plate 14 will be divided into first chamber and second chamber inside housing 1, its
In, first chamber is used to set blower fan 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 dividing plate 14 from Fig. 2
Room), blower fan 2 and heat exchanger 3 are located in first chamber, 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 present invention is installed on wall, after being followed successively by along the direction away from wall
Case 11, blower fan 2, heat exchanger 3, front cover shell 12.Blower fan 2 is dried in the case of operation to heat exchanger 3, i.e. air is from air inlet
Grid 111 enter in housing 1, are then flowed out from heat exchanger 3.Because the position of the correspondence heat exchanger 3 of front cover shell 12 is an opening, therefore
Will not heat exchanging device 3 air-out formed stop.Due to blower fan 2, (i.e. blower fan 2 is carried out directly towards heat exchanger 3 in the way of blowing
Blowing) 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 fin of heat exchanger 3.Preferably, should
Hydrophobic coating is graphene.Due to being coated with grapheme material on the fin of heat exchanger 3, and existing air-conditioner outdoor unit is changed
Generally hydrophilic layer is all coated on hot device.Compared with existing air-conditioner outdoor unit, the heat transfer efficiency of heat exchanger 3 of the invention is higher,
And due to the hydrophobicity of graphene, it in heating operations, can quickly roll off the condensed water on the surface of radiator 3.In addition,
The frost layer formed during due to air conditioner frosting is thicker, and the heat transfer of fin is relatively slowly transmitted to whole frost layer, but in defrost
When spreader surface frost layer be frost layer root, be that can form the position of moisture film earliest, formed moisture film after hydrophobic layer effect
Lower frost layer is just easy to be peeled off.Therefore, using the structure of air-conditioner outdoor unit of the invention, blower fan 2 directly blows to air
Heat exchanger 3, makes frost layer be easier to be blown off, in the outer space for being directly shed to heat exchanger 3.
In summary, due to the characteristic of graphene hydrophobic coating, heat exchanger of outdoor machine of air conditioner 3 is hot right with surrounding air
Stream mode, being changed into blowing from former air draught, (because the blower fan 2 of the present invention is located at the rear of heat exchanger 3, the wind that blower fan 2 is blown out is direct
Blow to heat exchanger 3).The air velocity of fin surface is very fast during blowing, and the globule formed on fin is easy to be carried away by the wind,
The situation of globule formation frost is greatly decreased.And air conditioner is when running defrosting, the heat exchanger fin and frost layer of outside
It is contiguously square into moisture film, and frost layer is just easy to be stripped, the frost layer of bulk will be blown off by being blown by wind one, greatly reduce sky
Adjust the defrosting time of device.
So far, combined preferred embodiment shown in the drawings describes technical scheme, still, this area
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these embodiments.Without departing from this
On the premise of the principle of invention, those skilled in the art can make equivalent change or replacement to correlation technique feature, these
Technical scheme after changing or replacing it is fallen within protection scope of the present invention.
