Description
Technical field
The utility model belongs to solar energy heat utilization field, relates to solar water heater pressure-bearing application technology, relates in particular to the solar water heater water tank with anticorrosion, anti-overheated function.
Background technology
At present, the water tank of commercially available solar water heater mainly contains pressure-bearing type and non-pressure-bearing type two big classes, and the water in the non-press-bearing water tank communicates with atmosphere, easily grow to be unfavorable for healthy impurity, and the bath comfort degree is poor.Water cleaning in the press-bearing water tank has the area of running water all can install, and easy to use, comfort level is good.
Existing press-bearing water tank adopts the mode of placing the heat exchange courage in pressure-bearing coil pipe water tank and the water more, pressure-bearing coil pipe water tank comes heat exchange by the coil pipe that is built in the heat collection water tank, not practical application of water in the heat collection water tank only is responsible for collecting the solar energy that obtains by solar vacuum heat-collecting pipe.The common volume of this water tank is excessive, and the water tank coil pipe is perishable, fouling is serious, influences heat exchange property, and service life is shorter.The pressure-bearing coil pipe water tank that also has takes the water that makes in the heating water tank by the coil pipe heat exchange, this mode thermal-arrest loop enclosed operation, and it is overheated to be easy under the situation preferably at irradiation, causes system normally not move, and security reliability is poor.
Placing the water tank of heat exchange courage in the water, also is bearing operation during use, but when work, overheat condition may appear in the thermal-arrest loop, and the heat exchange courage has by crowded flat danger.Therefore, be badly in need of a kind of anticorrosion, anti-overheated, safe and reliable solar water heater special water box of research and development.
The utility model content
For addressing the above problem, the purpose of this utility model provides the anticorrosion anti-overheated press-bearing water tank of a kind of solar water heater, adopt external open indirect heat exchange mode, this kind cisten mechanism is reasonable in design, manufactures easily, greatly broken through the restriction of production and processing level, and the water tank cost is relatively low, and is safe and reliable, corrosion resistant, heat-resisting, long-term operation performance is stable, the cost performance height.
For achieving the above object, the utility model is by the following technical solutions:
The anticorrosion anti-overheated press-bearing water tank of a kind of solar water heater, comprise heat exchange jacket, enamel inner container and shell, shell is provided with water inlet pipe and outlet pipe, water inlet pipe and outlet pipe are communicated with enamel inner container, the two ends of shell are separately installed with a left side, right aling cap, it is characterized in that: be furnished with heat exchange jacket on the outer wall of enamel inner container, heat exchange jacket is made by corrosion resistant plate, the internal face of heat exchange jacket is an arc surface, the internal face of heat exchange jacket fits tightly together by the outside wall surface of thermal conductivity good interface material and enamel inner container, the outside wall surface of heat exchange jacket has the installing hole of the vacuum heat collection pipe that is used to peg graft, installing hole is communicated with the inner chamber of heat exchange jacket, has inlet on the heat exchange jacket, overfall, steam drain; The position of overfall is higher than inlet, and the position of steam drain is higher than overfall.
Described heat exchange jacket is fan-shaped, and the arc angle of inner wall surface thereof less than 360 degree, is filled with insulation material in the periphery of enamel inner container and heat exchange jacket greater than 15 degree.
Described heat exchange jacket is a cylindrical shape, and the arc angle of inner wall surface thereof is 360 degree, is filled with insulation material in the periphery of heat exchange jacket.
Described boundary material has compressibility, is compressed between heat exchange jacket and the enamel inner container, and boundary material is covered with the heat exchange jacket internal face.
Described enamel inner container is made up of base material and enamel layer, and base material is made by low-carbon steel material, and enamel layer is laid on the inwall of enamel inner container.
Described heat exchange jacket with the relative position of enamel inner container is: the symmetrical center line of heat exchange jacket sector crosssection overlaps with the horizontal center line of enamel inner container circular section.
The relative position of described heat exchange jacket and enamel inner container is: the angular range of the horizontal center line of the symmetrical center line of heat exchange jacket sector crosssection and enamel inner container circular section is greater than 0 degree, less than 90 degree.
The utility model has following advantage:
Heat exchange jacket is to be made by stainless steel material, fits on the enamel inner container.The heat exchange jacket transfer working medium in heat does not directly contact with the enamel inner container internal hot-water, and because its open operation, inside does not have pressure, high temperature can not occur, therefore is difficult to be corroded.At present, existing enamel technology maturation is reliable, and this press-bearing water tank adopts enamel inner container, stable performance, and corrosion resistance is strong.Heat exchange jacket and enamel inner container are realized fitting tightly by boundary material compressible and that have a high-efficiency heat conduction performance, and its production technology is simple, and is easy to make.Because heat exchange mode is open indirect type, heat-transfer working medium dependence Natural Circulation flows and carries out the heat transmission, when water temperature is higher in the water tank, to engender heat build-up in the heat exchange jacket, heat-transfer working medium self temperature is quickened to raise and vaporization occurs, the heat-transfer working medium of vaporization attitude emits by gland steam exhauster again, and the result is that water tank superheating phenomenon can not occur.This product can be made into solar energy close-coupled bearing hot water device, and under the situation of environmental condition and collector area unanimity, its hot property surpasses other class solar energy close-coupled bearing hot water device.Well anticorrosion prevented that hot property was guaranteed the water heater life-span, the cost performance height.
