Abstract
The utility model discloses a flat type solar water heater which consists of a semi-closed insulation framework, heat absorbing tubes, a heat absorbing plate and a heat exchanging water tank. The semi-closed insulation framework is provided with a transparent glass plate at the upper part and forms a closed space inside; a plurality of communicated heat absorbing tubes are arranged in the closed insulation framework space, and the heat absorbing plate is arranged below the heat absorbing tubes; the heat exchanging water tank is provided with a heat exchanging tube, the inlet and outlet of which are respectively connected with outlet tubes and return tubes of the heat absorbing tubes through pipelines. The flat type solar water heater has the advantages of simple structure, low cost, frost prevention and high absorption rate, is suitable to be promoted and applied, and is in particular suitable for use in cold north area.
Description
Technical field
The utility model relates to a kind of flat solar water heater.
Technical background
Advantages such as solar water heater is safe, convenient, pollution-free with it, energy free consumption and being promote the wider application widely.But, in northern China,, weather cold has been subjected to considerable restraint because of making the application of solar water heater, and continuous low temperature can cause heat absorption rate low, and the upper and lower conduit road is easily freezing.Prior solar water heater is used vacuum heat collection pipe mostly simultaneously, causes adult higher, is unfavorable for promoting the use of in the rural area.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of simple in structure, adult is low, antifreeze, solar water heater that heat absorption rate is high.
For achieving the above object, the technical scheme that is adopted is:
A kind of flat solar water heater, constitute by semi-enclosed insulation framework, endothermic tube, absorber plate and heat-exchanging water tank, on described semi-enclosed insulation framework, be provided with transparency glass plate, form enclosure space in the insulation framework, in the insulation frame space of sealing, arrange a plurality of endothermic tubes that are interconnected, absorber plate is set below the endothermic tube, in described heat-exchanging water tank heat exchanger tube is set, the import and export of heat exchanger tube connects the outlet and the return pipe of endothermic tube respectively by pipeline.
The heat transfer medium of placing in above-mentioned endothermic tube is an anti-icing fluid.
Above-mentioned flat solar water heater, wherein said transparency glass plate is made of upper and lower layer glass plate, and the spacing between upper glass plate and the lower floor's glass plate is 10mm.
Owing to adopt said structure, endothermic tube and absorber plate place in the insulation frame space of sealing, pass through solar radiation, temperature in the insulation frame space is shone high more, simultaneously endothermic tube and absorber plate also absorb heat, have improved heat absorption rate, make that heat transfer medium in its endothermic tube is antifreeze to have a high heat, in heat-exchanging water tank, carry out transfer of heat then, heated the water in the heat-exchanging water tank; Adopted anti-icing fluid in the endothermic tube, therefore thoroughly solved antifreeze problem, be fit to very much the cold north and use; The advantage that the utility model also has is simple in structure, adult is low, be suitable for promoteing the wider application.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that Figure 1A-A is to cut-away enlarged view.
The specific embodiment
A kind of flat solar water heater, by semi-enclosed insulation framework 5, endothermic tube 10, absorber plate 13 and heat-exchanging water tank 2 constitute, on described semi-enclosed insulation framework 5, be provided with transparency glass plate 9, transparency glass plate is by last, following layer glass plate constitutes, spacing between upper glass plate 901 and the lower floor's glass plate 902 is 10mm, form enclosure space 12 in the insulation framework 5, in the insulation frame space 12 of sealing, arrange a plurality of endothermic tubes that are interconnected 10, the heat transfer medium of placing in the endothermic tube 10 is an anti-icing fluid, absorber plate 8 is set below the endothermic tube 10, absorber plate can adopt sheet iron to make, endothermic tube can adopt the iron pipe of diameter 4cm, absorber plate and endothermic tube surface are all coated pitch-dark, to improve heat absorption rate, heat exchanger tube 3 is set in described heat-exchanging water tank, heat exchanger tube 3 advance, outlet connects the outlet 4 and the return pipe 11 of endothermic tube respectively by pipeline 7, on heat-exchanging water tank 2 tops exhaust hole 1 is set, be provided with on it in the bottom, on the following water, downcomer 6, for preventing after the water heat exchange in the heat-exchanging water tank, heat scatters and disappears, and can coat heat-insulation layer in the heat-exchanging water tank outside.
