Description
Technical field
The utility model relates to the solar water heater field, specifically the splitting solar of a kind of U-shaped pipe heat collector and built-in enamel coil heat exchanger.
Background technology
At present, the Solar Enercy Fission Geyser water tank is mostly to adopt the pressure-bearing type structure, and heat exchange structure is divided into built-in heat exchange and external heat exchanger.Built-in heat exchanger mostly is welded structure, though the thermal efficiency improves, weld seam is perishable because of high pressure, high heat capacity, causes the medium pollution water tank that leaks outside; External heat exchanger water tank heat exchange area is large, and heat exchanger does not bear ambient pressure, but interlayer is difficult to enamel, makes its antiseptic property be difficult to guarantee, final heat exchanger damages, thereby causes whole water tank to be scrapped.On market, heat collector mainly adopts the thermal-arrest modes such as U-shaped pipe thermal-arrest, vacuum heat-pipe thermal-arrest and flat heat collecting now.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 deficiency, and the flat plate collector heat leakage is large and be not suitable for cold district, and overall thermal efficiency is not high.Though U-shaped copper pipe thermal conductivity factor is high, during the copper pipe welding, easily snap, and also the easy oxidation of copper, easily stop up circulating line, the hot strength of copper is low, also easily occurs that fatigue crack leaks the problems such as medium.
Summary of the invention
In order to solve above existing problems, we disclose the splitting solar of a kind of U-shaped pipe heat collector and built-in enamel coil heat exchanger, can greatly improve the service life of the thermal efficiency and the water tank of solar energy.
The utility model for achieving the above object, be achieved through the following technical solutions: the splitting solar of a kind of U-shaped pipe heat collector and built-in enamel coil heat exchanger, comprise water tank and heat collector, it is characterized in that: inner bag is installed in water tank, inner bag is equipped with enamel coil heat exchanger, the outer end of enamel coil heat exchanger arranges respectively medium circulation import and medium circulation outlet, with medium circulation, outlet is connected with the medium circulation pipeline through tank outer wall respectively in the medium circulation import, inner bag is provided with water inlet pipe and outlet pipe, and water inlet pipe, outlet pipe are connected with external pipe through water tank; Mounting vacuum tube in collector frame, vacuum tube is connected with collector frame by sealing ring, the U-shaped pipe of vacuum tube interpolation stainless steel, the upper end of U-shaped pipe is the heat pipe section, lower end is cold leg, and with the outlet of medium thermal-arrest, with the medium thermal-arrest, import is connected respectively at two ends, and the outlet of medium thermal-arrest exports and is connected with medium circulation with the medium circulation import of water tank respectively with the import of medium thermal-arrest, form closed circuit, the medium circulation pipeline is provided with water circulating pump station.
The heat exchanger of separated type solar water tank of the present utility model is that steel pipe rolls rear enamel and forms, solved built-in heat exchanger because of problems such as the corrosion of welding pressurized easy burn into stainless steel water tank pad are too fast and the external heat exchanger sandwich corrosion is too fast, simultaneously coil heat exchanger have take up space less, advantage that heat exchange area is large, greatly improved the heat exchange efficiency in water tank.
The utility model adopts pumping plant heat exchanging system to carry out forced circulation, greatly improves heat exchange efficiency.
The utility model is owing to taking said structure, and U-shaped pipe adopts stainless steel that following advantage is arranged: the U-shaped pipe of stainless steel is the argon arc welding welding, is difficult for snapping; Stainless steel is difficult for oxidation; Stainless steel tensile strength, be not prone to fatigue crack; Stainless steel has superior heat-insulating property.
Heat exchanger in U-shaped tube and tube road system, water tank forms the loop of sealing, by the heat exchange that loops of medium.This system can also realize: indirect heat exchange, bearing operation, and water quality is much cleaner; Bombing is without leakage, and system is the most stable; Longest-lived, the thermal efficiency is higher.
The in-built medium of U-shaped pipe of the present utility model, do not leak water in vacuum tube, so also non flouling behaviour, the long-term use also can not affect the efficiency of its thermal-arrest.Pressure-bearing and non-pressure two kinds of use are arranged, and what the damaged operational effect of its complete machine that also can not affect of vacuum tube appearance, and this system once in a while adopted is the connection of rigidity, can be by the problem of the aging and leakage brought without silica gel sealing ring.
