Below with reference to accompanying drawing 1 and Fig. 2 air-conditioner according to the utility model embodiment is described.
Air-conditioner according to the utility model embodiment comprises: off-premises station 100, indoor set 200, heat exchanger 300 and wind regime 400.
Particularly, as shown in Figure 1, off-premises station 100 links to each other with indoor set 200.As shown in Figure 2, wind regime 400 is located in indoor set 200 and the off-premises station 100, and wind regime 400 forms air-flow by motion in indoor set 200 and off-premises station 100, shown in the direction of arrow among Fig. 1.Air-flow flows out and the surrounding air heat exchange from the air outlet of off-premises station 100 and indoor set 200, and form negative pressure owing to gas flows out in off-premises station 100 and the indoor set 200, outside air flows into from the air inlet of described off-premises station 100 and indoor set 200 again, has formed intactly air-flow circulation like this.
Wind regime 400 can be any device that can form gas flow, for example the blade that is rotated by motor-driven.Blade one side is suction side (as the top of blade among Fig. 1), and opposite side is exhaust side (as the below of blade among Fig. 1).
Below with reference to Fig. 2 heat exchanger 300 according to the utility model embodiment is described.
As shown in Figure 2, a side and heat exchanger tube 310 that heat exchanger tube 310 is arranged in wind regime 400 air draught sides or the air draft side from the close-by examples to those far off become at least two rows to arrange with respect to wind regime 400, in other words, heat exchanger tube 310 have many row's structures and every row's heat exchanger tube 310 all different apart from the distance of wind regime 400, the heat exchanger tube 310 that makes every row's heat exchanger tube 310 and other row like this apart from the distance of wind regime 400 have far have near.Therefore, the flow velocity of the different row of airflow passes heat exchanger tube 310 also can be different, particularly, as shown in Figure 1, air flow stream is crossed the front-seat heat exchanger tube of the heat exchanger tube 311(near apart from wind regime 400) time wind speed greater than flowing through apart from arranging heat exchanger tube behind the wind regime 400 heat exchanger tube 312(far away) time wind speed.
A plurality of fins 320 be located at respectively on the heat exchanger tube 310 and the distance between the fin 320 on the front-seat heat exchanger tube 311 than little on the row's heat exchanger tube 312 of back, in other words, the spacing between the fin 320 on difference row's the heat exchanger tube 310 increases with the increase of the distance between heat exchanger tube 310 and the wind regime 400.
As shown in Figure 1, two rows are 311 and 312 the time before and after heat exchanger tube 310 is divided into, and the distance on the front-seat heat exchanger tube 311 between the fin 320 is less, i.e. density height, and the distance of then arranging between the fin 320 on the heat exchanger tube 312 is bigger, and promptly density is little.
Wind regime 400 is inhaled the air-flow (wind) of coming successively through two row's heat exchanger tubes 312 and at 311 o'clock, because it is lower away from the air-flow velocity at wind regime 400 places, from the not loss of throughput that back row's heat exchanger tube 312 is arranged air-flow when passing between the loose relatively fin 320, therefore improved the rate of heat exchange of fin 320 and air-flow on back row's heat exchanger tube 312.On the other hand, because the air-flow velocity near wind regime 400 places is higher, arrange when passing between the fin 320 closely relatively the throughput of air-flow from front-seat heat exchanger tube 311 and can not lose substantially, therefore improved the rate of heat exchange of fin 320 and air-flow on the front-seat heat exchanger tube 311 equally.
It will be appreciated by persons skilled in the art that when heat exchanger 300 is positioned at the air draft side of wind regime 400 principle of above-mentioned fin 320 density is suitable for equally and can obtains same heat exchange effect.For example, flow velocity was higher when air-flow was discharged from source of the gas 400, in that fin 320 back flow velocitys reduce through arranging closely on the front-seat heat exchanger tube, can guarantee that air communication is excessive when arranging loose fin 320 on the back row's heat exchanger tube of flowing through, and had improved rate of heat exchange.
Thus according to the heat exchanger 300 of the utility model embodiment, by the fin 320 of different density degree is set on difference row's heat exchanger tube 310, can under the prerequisite that does not increase fin 320 total amounts and increasing heat exchanger 300 sizes, make full use of the heat exchange efficiency of fin 320, effectively improve the heat exchanger effectiveness of whole heat exchanger 300.
On the other hand, by above-mentioned heat exchanger 300, can under the prerequisite that does not increase volume, improve refrigerating efficiency, energy efficient according to the air-conditioner of the embodiment of the invention.
According to an embodiment of the present utility model, be equipped with the flange hole on each fin 320, heat exchanger tube 310 inserts the flange hole so that fin 320 is fixed on the heat exchanger tube 310.
Heat exchanger tube 310 is a heat exchanger tube, and the circuitous at least two row's structures that are bent into.In addition, heat exchanger tube 310 also can be many many heat exchanger tubes that are connected in parallel to each other or are chained together.
Do as a wholely, heat exchanger can be cardinal principle yi word pattern, G type, L type or V-type, is preferably L type heat exchanger, as shown in Figure 1.
In the description of this specification, concrete feature, structure, material or characteristics that the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means in conjunction with this embodiment or example description are contained at least one embodiment of the present utility model or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete feature, structure, material or the characteristics of description can be with the suitable manner combination in any one or more embodiment or example.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiment under the situation that does not break away from principle of the present utility model and aim, scope of the present utility model is limited by claim and equivalent thereof.
