Abstract
The utility model discloses a heat exchange tube structure for a super hydrophilic tube type indirect devaporizer, which comprises a heat exchange tube made of metal aluminium foil. A metal aluminium foil titanium dioxide (TiO2) coating is arranged on the outside surface of the heat exchange tube. The heat exchange tube structure realizes super hydrophily of the surface of the heat exchange tube of the tube type indirect devaporizer, so that a even and thin water film is formed on the outside surface of the heat exchange tube, evaporation efficiency of water on the heat exchange tube is improved, and effects of high efficient, energy conservation and water conservation of the indirect devaporizer are further achieved.
Description
Technical field
The utility model belongs to air conditioner refrigerating heat and mass technical field, is specifically related to a kind of heat exchange tube structure of Superhydrophilic tube type indirect evaporative cooler.
Background technology
Primary air and auxiliary air are separated by heat exchange element in the indirect evaporation cooler, form water membrane by spray recirculated water at the heat exchange wall in the auxiliary air side, auxiliary air directly contacts with water and carries out the wet exchange of heat, the temperature maintenance of moisture film is at the wet-bulb temperature of auxiliary air, primary air with the heat transferred auxiliary air, is realized the purpose of cooling by heat exchange element, moisture film.The hydrophily of auxiliary air side heat exchange wall is one of key factor that influences the indirect evaporation cooler heat exchange efficiency in this process.
Present indirect evaporation cooler heat exchange wall flooring is metal aluminum foil more commonly, and the metal aluminum foil wall is non-hydrophilic surface, and water occurs doing at the skewness of wall easily, has influenced the efficiency of damp and hot exchanging of the auxiliary air side of indirect evaporation cooler.
Summary of the invention
The purpose of this utility model provides a kind of Superhydrophilic tube type indirect evaporative cooler heat exchange tube structure, by tube type indirect evaporative cooler heat exchanger tube aluminium foil outside wall surface is provided with metal aluminum foil TiO
2Coating is improved the hydrophilicity on heat exchanger tube surface, strengthens tube type indirect evaporative cooler auxiliary air side efficiency of damp and hot exchanging, has improved the temperature drop effect of indirect evaporation cooler.
The technical scheme that the utility model adopted is, a kind of Superhydrophilic tube type indirect evaporative cooler heat exchange tube structure comprises the heat exchanger tube of being made by metal aluminum foil, and the outer surface of heat exchanger tube is provided with metal aluminum foil TiO
2Coating.
Heat exchange tube structure of the present utility model, realized the Superhydrophilic on tube type indirect evaporative cooler heat exchanger tube surface, thereby make heat exchange pipe external surface form thin uniformly moisture film, improve the evaporation efficiency of water on heat exchanger tube, and then realize that indirect evaporation cooler is efficient, energy-conservation, the effect of water saving.And TiO is set outside heat exchanger tube
2The technology of coating is flexible, and is simple to operate, is applicable to large-scale production and monomer production.
Description of drawings
Fig. 1 is the tube type indirect evaporative cooler structural representation;
Fig. 2 is the structural representation of the utility model tube type indirect evaporative cooler heat exchanger tube.
Among the figure, 1. water-locator, 2. heat exchanger tube, 3. circulating pump, 4. TiO
2Coating.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The basic system of tube type indirect evaporative cooler mainly constitutes water circulation system by heat exchanger tube 2, water-locator 1, water circulating pump 3 as shown in Figure 1.
Superhydrophilic tube type indirect evaporative cooler heat exchange tube structure of the present utility model as shown in Figure 2, comprises the heat exchanger tube of being made by metal aluminum foil 2, and the tubular of heat exchanger tube 2 is smooth pipe or smooth elliptical tube, at the outer surface of heat exchanger tube 2 metal aluminum foil TiO is set
2Coating.
To have TiO
2The metal aluminum foil of coating is prepared into heat exchanger tube, and then is processed into tube type indirect evaporative cooler.Water-locator 1 sprays recirculated water at the tube type indirect evaporative cooler secondary side, and auxiliary air and heat exchanger tube 2 wall moisture films carry out the wet exchange of heat, and primary air with the heat transferred auxiliary air, is realized the purpose of cooling by heat exchanger tube 2 walls, moisture film.
The utility model is by being provided with TiO to tube type indirect evaporative cooler heat exchanger tube metal aluminum foil surface
2The structure of coating, change the surface heat functional characteristic of heat exchanger tube, realize the Superhydrophilic of heat exchanger tube aluminium foil surface, thereby make the outer just face of heat exchanger tube form thin uniformly moisture film, and then improve the evaporation efficiency of water on heat exchanger tube, realize that indirect evaporation cooler is efficient, energy-conservation, the effect of water saving.
