The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
The utility model provides a kind of heat exchanger, and it comprises fin and heat exchanger tube, and fin comprises inlet section and outlet section, and the inlet section is provided with first hydrophobic film 5; The outlet section is provided with first hydrophilic membrane 6.For example, as shown in Figure 2, first hydrophobic film 5 is connected with first hydrophilic membrane 6.This heat exchanger can or be arranged fin-tube heat exchanger for single fin-tube heat exchanger more.
The single fin-tube heat exchanger that the utility model provides can have a plurality of specific embodiments.First embodiment: as depicted in figs. 1 and 2, the single fin-tube heat exchanger of this embodiment, heat exchanger tube 1 are installed between the fin 2, and fin is arranged along heat exchanger tube 1 length direction, and for example fin 2 is the hydrophilic aluminium foil fin; Along between the adjacent fin of heat exchanger tube 1 vertical (being length direction) certain intervals is arranged, air enters along air intake direction 4a between fin, flows out from air-out direction 4b, carries out heat exchange with the fluid refrigeration agent in the heat exchanger tube 1; The 2a of fin basic unit is the partial structurtes of any fin in the fin 2, and the windward side of the 2a of fin basic unit is the inlet section, hydrophobic is carried out in its inlet section handle; The leeward side of the 2a of fin basic unit is the outlet section, and hydrophilic treated is carried out in its outlet section.Single fin-tube heat exchanger after the processing has following feature: form first hydrophobic film 5 on the surface of single fin-tube heat exchanger inlet section, the fin surface of heat exchanger outlet section forms first hydrophilic membrane 6.For example, the processing mode of first hydrophobic film 5 and first hydrophilic membrane 6 can adopt spraying, dipping, molecular vapor deposition or other attainable modes.
By above-mentioned processing, then can form the gradient of a sudden change or gradual change at the intersection of first hydrophobic film 5 and first hydrophilic membrane 6 can the surface (gradient can the surface be meant that the surface on a certain direction can gradually change, drop can be spontaneous can be low from the surface the place can high place move to the surface gradually).This gradient energy surface also can be as the first common hydrophilic membrane, and decay can appear in the hydrophily of fin surface and hydrophobicity in use for some time.When having only first hydrophilic membrane 6 and 5 complete obiterations of first hydrophobic film, the gradient on this surface just can disappear, so the time that gradient energy surface continues is obviously long than the first independent hydrophilic membrane time.And in the process of decay, more uniform gradient surface can appear for some time, help condensed water or defrost water more and discharge.
Certainly, the ratio of inlet section and outlet section width does not limit, and that is to say that the width of first hydrophobic film 5 and first hydrophilic membrane 6 does not limit, and can handle the width of first hydrophobic film 5 and first hydrophilic membrane 6 according to actual conditions.For example when this single fin-tube heat exchanger was applied in the heat pump outdoor unit evaporimeter, first hydrophobic film, 5 width can be wideer, and first hydrophilic membrane, 6 width can be narrow slightly, in the drainage speed, helps delaying the frosting cycle like this when accelerating defrost; When this single fin-tube heat exchanger is applied on the indoor evaporator, especially in the bigger area of humiture, can be wideer first hydrophilic membrane, 6 width, first hydrophobic film, 5 width are narrow slightly.In addition, the arrangement of this single fin-tube heat exchanger is not limit, when its inclination or when being parallel to horizontal plane and placing, under the effect of gravity, will speed up condensation water along fin 2 from the drainage rate of air intake on air-out direction, better effects if.
