Abstract
The utility model provides a built-in refrigerant heat transfer pipe of a heat pump water heater, which comprises a refrigerant pipe substrate, and is characterized in that a nano ceramic coating is coated on the outer surface of the refrigerant pipe substrate. Since the structure that the nano ceramic coating is coated on the outer surface of the refrigerant pipe substrate is adopted by the built-in refrigerant heat transfer pipe, the corrosion resistant performance of the refrigerant heat transfer pipe is improved; and since the thickness of a coating film is only one tenth of the thickness of an enamel coating, the heat resistance of the coating film is greatly reduced, the efficiency of the whole machine is improved, the energy consumption in the production process is simultaneously reduced, and environmentally-friendly production is achieved.
Description
Technical field
The utility model relates to a kind of built-in refrigerant heat-transfer pipe of heat pump water-heating machine, belongs to the improvement technology of the built-in refrigerant heat-transfer pipe of heat pump water-heating machine.
Background technology
The refrigerant heat-transfer pipe of the heat pump water-heating machine of prior art is installed in the press-bearing water tank inner bag, the long-time hot water with 60～70 ℃ of outer surface of tube body contacts, the HTHP gaseous coolant is at in-tube condensation, process discharges heat and is delivered to the water that stores in the inner water tank by tube wall, pipe external coating, thereby realizes heating the function of water.The refrigerant heat-transfer pipe of above-mentioned heat pump water-heating machine, generally be made by seamless cold drawing steel tube, owing to be soaked in the hot water for a long time, be the corrosion of chlorine in the anti-sealing, sulphur, fluorine plasma to body, generally adopt outer surface enamel to handle to the refrigerant heat-transfer pipe in the industry, its processing technology is: phosphatization in pickling in the outer sanding of body moulding-pipe-pipe external enamel coating-enamel curing-pipe-pipe.
In actual applications, there is following point in the refrigerant heat-transfer pipe of this structure: one, thermal resistance is big: refrigerant heat-transfer pipe outer wall enamel layer thickness is commonly 200～500um, and pottery is hot non-conductor, causes refrigerant heat-transfer pipe heat exchange effect to descend, and seriously reduces the complete machine thermal efficiency; Two, complex process: the enamel process is through 800 ℃ of high temperature, the inboard wall of tube body severe oxidation, and later stage acid cleaning process complexity all has harmful effect to pipe thickness, intensity; Three, poor reliability: because enamel bed thickness, crisp, the tiny damage in sintering, transportation and installation process or show-through all can cause body to be corroded; 4, energy consumption is big: the enamel process technology requires high, does not meet the environmental protection and energy saving requirement.
Summary of the invention
The purpose of this utility model is to address the above problem and provides a kind of corrosion resisting property good, and thermal resistance is little, and technology is simple, the reliability height, and energy consumption is little, and can realize the built-in refrigerant heat-transfer pipe of heat pump water-heating machine of the production process of environmental protection and energy saving.
The technical solution of the utility model is: a kind of built-in refrigerant heat-transfer pipe of heat pump water-heating machine, comprise refrigerant pipe matrix, and it is characterized in that being coated with nano ceramic coat on the outer surface of described refrigerant pipe matrix.
Described refrigerant pipe matrix adopting solid drawn tube is made.
Described refrigerant pipe matrix adopting seamless aluminium tubing is made.
Described refrigerant pipe matrix adopting seamless copper pipe is made.
Described refrigerant pipe matrix adopting gapless stainless steel tube is made.
The utility model is owing to adopt the structure that is coated with nano ceramic coat on the outer surface that refrigerant pipe matrix is arranged, not only improved the corrosion resisting property of refrigerant heat-transfer pipe, and because coating thickness has only 1/10th of enamel layer, therefore, significantly reduced and be coated with film resistance, improve overall efficiency, reduced the production process energy consumption simultaneously, realized environmental protection production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, the built-in refrigerant heat-transfer pipe of the utility model heat pump water-heating machine comprises refrigerant pipe matrix 1, is coated with nano ceramic coat 2 on the outer surface of described refrigerant pipe matrix 1.
Described refrigerant pipe matrix 1 adopts solid drawn tube, seamless aluminium tubing, seam copper pipe or gapless stainless steel tube to make.
The processing process of the utility model refrigerant heat-transfer pipe is: after the moulding of refrigerant heat-transfer pipe body sanding is carried out on the body surface and handle, by dip-coating mode even coating nano ceramic coating outside pipe, enter after coating drains in 180 ℃ of bakers and be incubated 20 minutes, the nano ceramic coat thickness that solidifies after finishing is 20～30um, and formation and the similar film forming of ceramic structure, this coating possesses high rigidity, hydrophobic, medium corrosion resistance, multinomial excellent properties such as heat-resisting quantity.
