Described first hot the assembly 10 and second hot assembly 20 phase lap-joints of converting of converting, described first heat exchange fin 40 and second of converting hot assembly 10 heat exchange fin 40 of hot assembly 20 overlap together (among Fig. 6 shown in the A) of converting, realize that with this lap-joint prevents the effect of leaking out, leaking, the width of overlaid part is preferably 1.5 ~ 2mm.In order to realize above-mentioned overlapping, first the convert heat exchange fin 40 of hot assembly 20 of hot assembly 10 and second of converting need be staggeredly arranged each other.Described second hot assembly 20 and the 3rd hot assembly 30 phase lap-joints of converting of converting, described second heat exchange fin 40 and the 3rd of converting hot assembly 20 heat exchange fin 40 of hot assembly 30 overlap together (among Fig. 7 shown in the C) of converting, realize that with this lap-joint prevents the effect of leaking out, leaking, the width of overlaid part is preferably 1.5 ~ 2mm.In order to realize above-mentioned overlapping, second the convert heat exchange fin 40 of hot assembly 30 of hot assembly 20 and the 3rd of converting need be staggeredly arranged each other.
In the above-mentioned ultrathin heat exchanger, combination by double heat exchanger tube and single heat exchanger tube, can reduce its thickness, to satisfy the space requirement of wall-hanging air conditioner indoor unit, and by the first trapezoidal breach and second breach are set respectively on corresponding heat exchange fin, and between heat exchange fin, adopt the interference overlapping mode, can further satisfy the space requirement of wall-hanging air conditioner indoor unit.Adopt the new design of refrigerant flow simultaneously, arrange heat exchanger tube in each pipeline includes and efflux heat exchanger tube and move towards along specific stream according to wind direction, satisfy reliability requirements such as condensation when can realize the heat exchange maximum effect again.
As shown in Figure 8, be the structural representation of the utility model wall-hanging air conditioner indoor unit.
This wall-hanging air conditioner indoor unit comprises casing 200, axial-flow fan 300 and aforesaid ultrathin heat exchanger 100, described axial-flow fan 300 and ultrathin heat exchanger 100 are located in the described casing 200, the top of described casing 200 is provided with air inlet 202, and described ultrathin heat exchanger 100 is between described air inlet 202 and axial-flow fan 300 and the described axial-flow fan 300 of semi-surrounding.
Because countercurrent flow is most effective, therefore make temperature rise (or temperature drop) direction of refrigerant opposite with temperature rise (or temperature drop) direction of wind, can reach preferable countercurrent flow effect.The air inlet 202 of this wall-hanging air conditioner indoor unit is located at the top, ultrathin heat exchanger 100 is during as evaporimeter, the air quantity maximum at top, the import 511,521,531 of described first pipeline 51, second pipeline 52 and the 3rd pipeline 53 just in time designs in this top area.
When ultrathin heat exchanger 100 as evaporator operation during at refrigeration mode, the stream of described first pipeline 51 is: refrigerant enters from first heat exchanger tube 601, along second heat exchanger tube 602, the the 7th to the 12 heat exchanger tube 607 ~ 612, the 6th heat exchanger tube 606 to the 5th heat exchanger tubes 605 flow out, the temperature of refrigerant is raise, because being ecto-entad, the direction of wind reduces, just in time belong to countercurrent flow, thereby has preferable heat exchange effect, and the heat exchanger tube quantity of first pipeline, 51 processes and other two pipelines 52,53 is the same, all be 5 U-shaped pipes, make that the coolant quantity deviation of each pipeline is little, the condensation problem that can avoid bias current to cause; The stream of second pipeline 52 is: refrigerant enters from the 20 heat exchanger tube 620, flow out along the 21 to the 25 heat exchanger tube 621 ~ 625, the 18 heat exchanger tube 618, the 17 heat exchanger tube 617, the 3rd heat exchanger tube 603 to the 4th heat exchanger tubes 604, the temperature rise direction of refrigerant also is identical with the temperature drop direction of air, belong to countercurrent flow, has preferable heat exchange efficiency, and the quantity of the U-shaped pipe of process is 5, namely there are the U pipe that effluxes and interior row's U to manage, guaranteed that the heat exchange of whole ultrathin heat exchanger 100 evenly reaches efficient; The stream of the 3rd pipeline 53 is: refrigerant is entered by the 13 heat exchanger tube 13, along the 14 to the 16 heat exchanger tube 614 ~ 616, the 26 heat exchanger tube 626, the 19 heat exchanger tube 619, and the 27 to the 30 heat exchanger tube 627 ~ 630, flowed out by the 30 heat exchanger tube 630, because the 3rd 5 of the U-shaped pipe lazy weights of converting hot assembly 30, and choose 3 U-shaped pipes by converting second in the hot assembly 20, simultaneously because the 3rd hot assembly 30 of converting is single row configuration, heat exchange is better, so only need to choose 3 U pipes the second interior row who converts in the hot assembly 20, also can reach preferable heat exchange effect.
The similar refrigeration of principle that described heat exchanger tube 100 heats as condenser, just refrigerant flow direction and refrigeration are opposite.
Described first heat exchange fin 40 of converting hot assembly 10 is provided with the first trapezoidal breach 402, hypotenuse by the first trapezoidal breach 402, can realize and casing 200 in base between formation face overlap joint, it is seamless overlap joint, in case leak-stopping wind, drainage, described first condensed water of converting on the hot assembly 10 can flow in the back water receiving tank of the base in the casing 200, is discharged to the place of appointment again by osculum.
Described second heat exchange fin 40 of converting hot assembly 20 is provided with the second trapezoidal breach 404, and by the hypotenuse of the second trapezoidal breach 404, condensed water is rejected to the following the 3rd smoothly and converts on the hot assembly 30 in the time of can being convenient to freeze.Convert condensed water on the hot assembly 20 when its heat exchange fin 40 flows down when second, because the existence of the second trapezoidal breach 404, condensed water can be below the carrying out the transition to of the hypotenuse nature of the second trapezoidal breach 404 the 3rd convert on the heat exchange fin of hot assembly 30, flow at last in the preceding rhone of the base in the casing 200, be discharged to the place of appointment again by osculum.If the second trapezoidal breach 404 is not set, but directly with meeting at right angles, because angle changes too greatly, second convert the condensed water on the hot assembly 20 can drip at right angle corner place gravitate and flows less than the following the 3rd and convert on the heat exchange fin 40 of hot assembly 30, does not allow water to cause user's complaint where or does not meet safety requirements and the water droplet that drips may splash other.For ease of when refrigeration second convert condensed water on the hot assembly 20 can be rejected to the following the 3rd smoothly and convert on the hot assembly 30, the included angle B (shown in Figure 6) that the hypotenuse and second of described trapezoidal second breach 404 is converted between the outer side edges of heat exchange fin 40 of hot assembly 20 preferably is in 130 °.
Inner space according to wall-hanging air conditioner indoor unit is arranged and the air intake mode, can adjust respectively the convert pitch of fins etc. of heat exchanger tube length, row number, radical, overlap joint angle and heat exchange fin of hot assembly of ultrathin heat exchanger, with shape need and the radiating effect that satisfies wall-hanging air conditioner indoor unit.
The utility model is not limited to above embodiment, under the disclosed technology contents of above-mentioned embodiment, can also carry out various variations.Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
