Description
Technical field
The present invention relates to the solar water heater field, is the splitting solar of a kind of U-shaped pipe heat collector and detachable heat exchanger.
Background technology
At present, the Solar Enercy Fission Geyser water tank mostly is 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.Heat collector mainly adopts the thermal-arrest modes such as U-shaped pipe thermal-arrest, vacuum heat-pipe thermal-arrest and flat heat collecting on the market 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 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.U-shaped tube material generally all adopts copper pipe, though the copper thermal conductivity factor is high, easily snaps during the copper pipe welding, and also the easy oxidation of copper, easily stop up circulating line, the hot strength of copper is low, fatigue crack also easily occurs and 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 detachable heat exchanger, the service life that can greatly improve the thermal efficiency and the water tank of solar energy.
The present invention 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 detachable heat exchanger, comprise water tank and heat collector, it is characterized in that: inner bag is installed in the water tank, detachable heat exchanger is housed in the inner bag, the outer end of heat exchanger arranges respectively exhaust outlet, medium circulation import and medium circulation outlet, exhaust outlet connects air bleeding valve, the medium circulation import is connected with medium circulation all passes 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 is connected with external pipe; Mounting vacuum tube in the collector frame, vacuum tube links to each other 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, the lower end is cold leg, import links to each other with the medium thermal-arrest with the outlet of medium thermal-arrest respectively at two ends, and the outlet of medium thermal-arrest exports with medium circulation with the medium circulation import of water tank respectively with the import of medium thermal-arrest and links to each other, and forms closed circuit.
The heat exchanger of separated type solar water tank of the present invention is stainless steel integrated stretching, heat exchange efficiency and the antiseptic property of water tank have greatly been improved, heat exchanger is detachable, be convenient to maintenance, the phenomenon that causes whole water tank to be scrapped because of heat exchanger existing problems, the service life of greatly having improved water tank have been avoided; 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.
Heat collector of the present invention is to insert the U-shaped pipe of stainless steel in ordinary vacuum tube, and near the vacuum tube inwall, cold leg is in the lower end in the upper end for U-shaped pipe heat pipe section, and height of formation is poor, accelerates the circulation rate of medium, improves the water tank heat exchange efficiency.
The present invention 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 is not prone to fatigue crack; Stainless steel has superior heat-insulating property.
Heat exchanger in U-shaped tube and tube road system, the 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.
Heat collector of the present invention adds U-shaped pipe and in-built medium, do not leak water in the vacuum tube, thus also non flouling behaviour, the long-term efficient that also can not affect its thermal-arrest of using.Two kinds of use of pressure-bearing and non-pressure-bearing are arranged, and what the once in a while damaged operational effect that also can not affect its complete machine of vacuum tube appearance, and this system adopted is the connection of rigidity, can be by the problem of the aging and leakage that brings without silica gel sealing ring.
