Description
Technical field
The present invention relates to the solar water heater field, be specifically related to the separated type solar hot-water heating system of a kind of three lumen heat collectors and built-in heat exchanger.
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, provide a kind of can significantly improve solar energy the three lumen heat collectors in service life of the thermal efficiency and water tank and the separated type solar hot-water heating system of built-in heat exchanger.
the present invention solves the problems of the technologies described above the technical scheme that adopts: the separated type solar hot-water heating system of a kind of three lumen heat collectors and built-in heat exchanger, be provided with water tank and heat collector, it is characterized in that: inner bag is installed in described water tank, inner bag is equipped with detachable heat exchanger, the outer end of heat exchanger arranges respectively exhaust outlet, medium circulation import and medium circulation outlet, 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, and 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, and 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, heat exchanger in water tank is stainless steel integrated stretching, heat exchange efficiency and the antiseptic property of water tank have greatly been improved, heat exchanger is detachable, is convenient to maintenance, has avoided the phenomenon that causes whole water tank to be scrapped because of the heat exchanger existing problems, greatly improved the service life of water tank, in order further to improve heat exchange efficiency, heat exchanger is inserted in the medium circulation import inner, effectively that heat delivery is inner to 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.
