Abstract
The utility model discloses a heat exchanger of a heat pump water heater. The heat exchanger comprises a heat radiation fin and a heat exchange tube, wherein the heat exchange tube is inserted in the heat radiation fin in a penetrating way, and the heat radiation fin is in a double-layer structure and comprises an aluminum foil at the inner layer and a composite coating at the outer layer. Through the novel characteristics of the composite coating, the hydrophilicity and the self-cleaning capability of the heat exchanger can be effectively improved, so the flow resistance is reduced, and the service life of the heat exchanger is prolonged.
Description
Technical field
The utility model relates to air-conditioning technical field, more particularly, relates to a kind of heat exchanger of Teat pump boiler.
Background technology
Heat exchanger is the important component part of Teat pump boiler, and its quality and heat exchange effect directly influence the heating effect of Teat pump boiler.The heat exchanger of Teat pump boiler is made up of with the aluminium foil that contacts with the tube wall tensioner heat exchanger tube.Aluminium foil is generally fin structure, and purpose is to improve heat exchange efficiency through increasing heat exchange area, so number of fins is many more, heat exchange area is big more.But more and more when the quantity of fin, the spacing between the fin is more and more littler, and water can form the water bridge between fin, resistance and noise are all increased.
The aluminium foil surface of the heat exchanger of conventional heat pump water heater scribbles one deck hydrophilic layer, and purpose is to make water be more prone to mobile at heat exchange surface.But this hydrophilic layer life-span is very short, and after general half a year, hydrophily will descend significantly, thereby water also can descend in its surface mobility.In addition, because condensed water has certain impurity, condensed water sticks to fin surface with impurity in that the fin upper reaches is out-of-date, and especially under the closeer situation of fin, the accumulation of impurity is very fast.Behind the long-pending full dirt of heat exchanger thermal resistance is increased; The hydrophily, the windage that also influence aluminium foil simultaneously increase; Make that the Teat pump boiler heat exchange efficiency descends, energy consumption increases, and dust quickens the burn into oxidation of coming off of water wetted material and aluminium foil, the service life of shortening heat pump water heater easily with dirt.
The utility model content
The utility model purpose provides a kind of heat exchanger with Teat pump boiler of self-purification capacity, Superhydrophilic in order to overcome the deficiency that above-mentioned prior art exists.
The technical scheme that the utility model adopts is: a kind of heat exchanger of Teat pump boiler, comprise radiating fin and the heat exchanger tube that interts in radiating fin, and said radiating fin is a double-decker, comprises the aluminium foil of internal layer, outer field composite coating.
The thickness of the composite coating of said indoor heat exchanger is 50nm-2000nm.
The composite coating of said indoor heat exchanger forms after the coating colloidal sol drying for coating colloidal sol is sprayed on the heat exchanger.
Compared with prior art, the utlity model has following advantage:
1, mixed coating can effectively improve the hydrophily of the radiating fin of heat exchanger, reduces flow resistance, improves heat exchange efficiency;
2, mixed coating has the self-purification function of sterilization de-sludging, increases service life, reduction flow resistance, the raising heat exchange efficiency of heat exchanger.
Description of drawings
Fig. 1 is the structural representation of heat exchanger of a kind of Teat pump boiler of the utility model;
Fig. 2 is the single chip architecture sketch map of radiating fin of a kind of Teat pump boiler of the utility model.
The specific embodiment
The utility model is a kind of heat exchanger of Teat pump boiler, and structure is as shown in Figure 1, comprises heat exchanger tube 4 and radiating fin 1, and heat exchanger tube 4 dishes are inserted in the radiating fin 1.Compare with general coil exchanger, the radiating fin 1 of the utility model is two layers structure, and is as shown in Figure 2, is respectively aluminium foil 2, the outer field composite coating 3 of internal layer from inside to outside.
The component and the percent concentration thereof of the preferred version of titanium mixture are following: TiO
270%, CuO 10%, Ag
2O 10%, ZnO 10%.
Manufacture process is following:
At first, will contain the radiating fin 1 and heat exchanger tube 4 expand tube moulding of hydrophilic layer, and on heat exchanger tube 4, insert little bending, after welding and the leak detection, the heat exchanger that leak detection is qualified is also dry with cleaning agent washing radiating fin 1.
Then, preparation coating colloidal sol, and coating colloidal sol is sprayed on the radiating fin with certain pressure and speed; The heat exchanger that is coated with coating colloidal sol is toasted in 110 ℃ to 150 ℃ temperature range, and dry back forms composite coating 3 on radiating fin.
At last, again this radiating fin 1 that contains composite coating 3 is assembled on the heat exchanger.
The heat exchanger of a kind of Teat pump boiler of the utility model, under the ultraviolet ray irradiation in sunlight or indoor light, nano-TiO
2Produce under the photocatalysis, the electronics in composite coating 3 encourages, and produces the hole of electronegative electronics and positively charged; Electronics makes the hydrogen reduction in air or the water; Generating hydrogen peroxide solution, then works to the direction of oxidized surface hydrone in the hole, produces the basic atomic group of hydrogen-oxygen (hydroxyl); Thereby can decompose, remove the various organic matters attached to composite coating 3 surfaces, decomposition efficiency is 100%.
Under unglazed environment, then by the CuO in the composite coating 3, Ag
2The catalysis of O; Electronics in the composite coating 3 also can produce the hole of electronegative electronics and positively charged; Thereby form hydrogen peroxide solution and the basic atomic group of hydrogen-oxygen (hydroxyl); Decompose, remove attached to harmful substances such as the various organic matters on composite coating 3 surfaces and airborne formaldehyde, benzene, oil smoke, its decomposition efficiency reaches more than 80%.
