Detailed description of the invention
In order to make the technical solution of the utility model clearly, below in conjunction with accompanying drawing, heat exchanger of the present utility model and air-conditioner are described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model and to be not used in restriction the utility model.
As shown in Figure 1, the fin that heat exchanger of the present utility model comprises many row's heat exchanger tubes and is set on heat exchanger tube, fin for increasing the external surface area of heat exchanger tube or internal surface area, thus reaches the object improving heat exchange efficiency.The from top to bottom stacked setting of many rows heat exchanger tube, and the cross section of heat exchanger takes the shape of the letter U (top view of the heat exchanger namely in Fig. 1 takes the shape of the letter U), is bent to form U-shaped by heat exchanger tube, makes the tube side of heat exchanger tube longer, thus improve the heat transfer effect of heat exchanger.Heat exchanger is divided into the first heat exchanging part 1 and the second heat exchanging part 2, and the first heat exchanging part 1 is placed in the top of the second heat exchanging part 2.For the air volume adjustment of the air quantity and the second heat exchanging part 2 that ensure the first heat exchanging part 1 is even, the windage of the first heat exchanging part 1 is greater than the windage of the second heat exchanging part 2.
This heat exchanger structure is applicable to the situation that fan assembly is arranged on close first heat exchanging part 1, and because the first heat exchanging part 1 is near fan assembly, the air quantity of the first heat exchanging part 1 is greater than the air quantity of the second heat exchanging part 2.The windage of the first heat exchanging part 1 is greater than the windage of the second heat exchanging part 2, and the air volume adjustment achieving the first heat exchanging part 1 and the second heat exchanging part 2 is even, thus improves the heat transfer effect of heat exchanger.
As a kind of embodiment, the spacing of fin S1 of the first heat exchanging part 1 is less than the spacing of fin S2 of the second heat exchanging part 2, refers to Fig. 2 and Fig. 3.Namely the density of the fin 3 of the first heat exchanging part is greater than the density of the fin 4 of the second heat exchanging part, thus makes the windage of the first heat exchanging part 1 be greater than the windage of the second heat exchanging part 2.
In the use procedure of reality, the first heat exchanging part 1 is arranged near fan assembly place, and now the air quantity of the first heat exchanging part 1 is greater than the air quantity of the second heat exchanging part 2.Windage due to the first heat exchanging part 1 is greater than the windage of the second heat exchanging part 2, therefore, the air quantity of the first heat exchanging part 1 reduces, thus reach the uniform object of air volume adjustment of the first heat exchanging part 1 and the second heat exchanging part 2, eliminate the impact of wind field skewness heat exchanging effect, improve the heat transfer effect of heat exchanger.Preferably, the scope of the difference of the spacing of fin S2 of the second heat exchanging part 2 and the spacing of fin S1 of the first heat exchanging part 1 is 0.5 millimeter ~ 1.0 millimeters.
As another kind of embodiment, the heat exchanger tube row of the first heat exchanging part 1 is greater than the heat exchanger tube row of the second heat exchanging part 2.Preferably, the heat exchanger tube row of the first heat exchanging part 1 row more than the heat exchanger tube row of the second heat exchanging part 2.In this embodiment, keep the spacing of fin S1 of the first heat exchanging part 1 to equal the spacing of fin S2 of the second heat exchanging part 2, and from the second heat exchanging part 2, there is different windage sizes by the first heat exchanging part 1 first heat exchanging part 1 that realizes different from the heat exchanger tube row of the second heat exchanging part 2.
The present embodiment is equally applicable to the situation that fan assembly is arranged on close first heat exchanging part, because the air quantity of the first heat exchanging part 1 is large, exchange capability of heat is strong, therefore by the heat exchanger tube row of suitable increase by first heat exchanging part 1, simultaneously, the heat exchanger tube row of corresponding minimizing second heat exchanging part 2, makes the exchange capability of heat of the first heat exchanging part 1 and the second heat exchanging part 2 balanced, realizes the uniform object of air volume adjustment of the first heat exchanging part 1 and the second heat exchanging part 2.
As another kind of embodiment, the fin 3 of the first heat exchanging part is slitted fin, and the fin 4 of the second heat exchanging part is plain fin, keeps the spacing of fin of the first heat exchanging part 1 to equal the spacing of fin of the second heat exchanging part 2 simultaneously.Slitted fin in the present embodiment can adopt X-type slitted fin or other slitted fins.Because slitted fin has higher heat transfer effect compared to plain fin, therefore, the fin 3 of the first heat exchanging part selects slitted fin can increase the heat exchange amount of the first heat exchanging part 1, make the heat transfer effect of the first heat exchanging part 1 and the second heat exchanging part 2 suitable, realize being uniformly distributed of the first heat exchanging part 1 and the second heat exchanging part 2 air quantity.
As further improvement, from the second heat exchanging part 2, there is different windage sizes for realizing the first heat exchanging part 1, the assembled scheme of above-mentioned different embodiment can also be adopted.As, the spacing of fin of the first heat exchanging part 1 is less than the spacing of fin of the second heat exchanging part 2 and the heat exchanger tube row of the first heat exchanging part 1 is greater than the heat exchanger tube row of the second heat exchanging part 2.Or the spacing of fin of the first heat exchanging part 1 is less than the spacing of fin of the second heat exchanging part 2 and the fin 3 of the first heat exchanging part is slitted fin, and the fin 4 of the second heat exchanging part is plain fin.Or the heat exchanger tube row of the first heat exchanging part 1 is greater than the heat exchanger tube row of the second heat exchanger tube 2 and the fin 3 of the first heat exchanging part is slitted fin, and the fin 4 of the second heat exchanging part is plain fin.
As shown in Figure 4, the air quantity of the first heat exchanging part 1 of heat exchanger of the present utility model is Q1, and the air quantity of the second heat exchanging part 2 is Q2.Can clearly find out from figure, the air quantity Q1 of the first heat exchanging part 1 equals the air quantity Q2 of the second heat exchanging part 2 substantially, and the air volume adjustment of the first heat exchanging part 1 and the second heat exchanging part 2 is even.
The utility model additionally provides a kind of air-conditioner, comprises the heat exchanger of fan assembly 5 and above-mentioned any one.In the present embodiment, for ensureing balanced heat transfer effect, fan assembly 5 is positioned at the top of heat exchanger, and namely the first heat exchanging part 1 is arranged near fan assembly place, and the second heat exchanging part 2 is placed at the below of the first heat exchanging part 1.Preferably, fan assembly 5 is axial flow blower, cross flow fan or centrifugal blower.
Heat exchanger of the present utility model and air-conditioner, by the different settings of the first heat exchanging part from the windage size of the second heat exchanging part, thus ensure that the air quantity of the first heat exchanging part and the second heat exchanging part is uniformly distributed, improve the heat transfer effect of heat exchanger.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
