Technical field
The present invention relates to the solar water heater field, be specifically related to a kind of three lumen heat collectors and embedded heat exchanger separated type solar hot-water heating system.
Background technology
Solar Enercy Fission Geyser is all to adopt the pressure-bearing type structure at present, and heat exchange structure is divided into built-in heat exchange and external heat exchanger.Built-in heat exchanger is stainless heat exchanger, and heat exchange efficiency is high, has etching problem but usually adopt the stainless steel welding to make, and greatly reduces the service life of water tank, and final heat exchanger damages, thereby causes whole water tank to be scrapped; External heat exchanger water tank heat exchange area is large, and heat exchanger does not bear ambient pressure, but heat transferring medium can cause corrosion to the inner water tank outside and the inboard formed interlayer heat exchanger of heat exchanger equally, thereby causes whole water tank to be scrapped.The thermal-arrest mode that adopts at present is U-shaped pipe heat collector, energy vacuum heat pipe collector, flat plate collector.U-shaped pipe heat collector less than normally causes heat absorption abundant not because its U-shaped tube outer surface is long-pending, makes heat in vacuum tube lose whole collecting efficiency on the low side, and mostly is welding and makes and have etching problem; The collecting efficiency of energy vacuum heat pipe collector is high, but along with the increase vacuum of service life descends gradually, makes its collecting efficiency not enough, and the flat plate collector heat leakage is large and be not suitable for cold district, and overall thermal efficient is not high.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, and a kind of three lumen heat collectors and embedded heat exchanger separated type solar hot-water heating system that can significantly improve the service life that gets the thermal efficiency and water tank of solar energy is provided.
the present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of three lumen heat collectors and embedded heat exchanger separated type solar hot-water heating system, comprise water tank and heat collector, it is characterized in that: inner bag is installed in described water tank, inner bag and dome head form embedded heat exchanger, the outer end of heat exchanger arranges respectively exhaust outlet, medium circulation import and medium circulation outlet, medium circulation outlet afterbody is made as bend pipe, the medium circulation import is deep into heat exchanger inside, the exhaust outlet air valve that runs in, the medium circulation import is connected with medium circulation passes respectively tank outer wall and is connected with the medium circulation pipeline, inner bag is provided with water inlet pipe and outlet pipe, water inlet pipe, outlet pipe passes water tank and communicates with atmosphere, the cold pipe of thermal-arrest and thermal-collecting tube are installed in described heat collector, the cold pipe of thermal-arrest is connected to the afterbody of thermal-collecting tube, the cold tube end of thermal-collecting tube and thermal-arrest is provided with the outlet of medium thermal-arrest and the import of medium thermal-arrest, vacuum tube is connected with thermal-collecting tube by sealing ring, and glass heat absorbing pipe is fixed in vacuum tube by metallic support.
The present invention is owing to taking said structure, and heat exchanger is embedded heat exchange structure, and heat exchanger is comprised of dome head and inner bag, heat exchange area is large, improved greatly the heat exchange efficiency of water tank, the whole enamel of heat exchanger and inner bag has been avoided the etching problem of water tank, the service life of greatly having improved water tank; Medium circulation outlet afterbody is made as bend pipe, and the medium circulation import is deep into heat exchanger inside, has accelerated the circulation rate of medium, greatly improves the heat exchange efficiency of water tank; Medium is housed the vacuum tube of heat collector and built-in glass heat absorbing pipe can fully absorb the heat of vacuum tube, and the cold pipe of thermal-arrest is connected to the tail end of thermal-collecting tube, greatly improved the temperature difference of circulatory mediator, accelerated the circulation rate of medium, effectively the heat with heat collector is transferred in water tank, has improved greatly the collecting efficiency of water heater.
