Description

The separated type solar of a kind of finned heat collector and built-in snakelike enamel heat exchanger

Technical field

The utility model relates to the solar water heater field, is the separated type solar of a kind of finned heat collector and built-in snakelike enamel heat exchanger.

Background technology

The Solar Enercy Fission Geyser water tank is mostly to adopt the pressure-bearing type structure at present, and heat exchange structure is divided into built-in heat exchange and external heat exchange.Built-in heat exchanger, owing to being subject to the water tank capacity restriction, exists size of heat exchanger generally little, affects the heat exchange efficiency of system; 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 domestic market, heat collector has the thermal-arrest modes such as U-shaped tube type vacuum pipe thermal-arrest, all-glass vacuum tube thermal-arrest, heat pipe vacuum tube hot collector and flat plate collector.U-shaped tube type vacuum 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; Although the hot collecting efficiency of glass vacuum pipe heat collector is high, occupation rate of market is large, and because it can not bearing operation, easily bursting by freezing, leak water in pipe, if a breakage is arranged in running, whole system will quit work; And the thermal capacitance of vacuum tube is larger, solar energy first will could be exported hot water to the heating of the water in vacuum tube, and to night, the hot water in vacuum tube can not be fully utilized, and cause certain thermal loss; 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.The flat plate collector heat leakage is large and be not suitable for cold district, and overall thermal efficiency is not high.

Summary of the invention

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of can significantly improve solar energy the finned heat collector in service life of the thermal efficiency and water tank and the separated type solar of built-in snakelike enamel heat exchanger.

The utility model solves the problems of the technologies described above adopted technical scheme: the separated type solar of a kind of finned heat collector and built-in snakelike enamel heat exchanger, comprise water tank and heat collector, it is characterized in that: inner bag is installed in water tank, inner bag one end is equipped with built-in snakelike enamel heat exchanger, the outer end of heat exchanger arranges respectively blast pipe, medium circulation import and medium circulation outlet, blast pipe is provided with exhaust 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, water inlet pipe, outlet pipe is connected with external pipe through water tank, mounting vacuum tube in described collector frame, vacuum tube is connected with collector frame by sealing ring, the U-shaped thermal-collecting tube of vacuum tube interpolation, on U-shaped thermal-collecting tube, pipe is thermal-collecting tube, lower pipe is the cold pipe of thermal-arrest, thermal-collecting tube kalamein fin, metal fin is close to the vacuum tube inner pipe wall, thermal-collecting tube is connected respectively thermal-arrest outlet and thermal-arrest import with the cold pipe of thermal-arrest, thermal-arrest outlet and thermal-arrest import are respectively through collector frame, export and be connected with medium circulation with the medium circulation import of water tank by the medium circulation pipeline, form loop.

Heat exchanger of the present utility model is enamel serpentine heat exchanger structure, and inside and outside wall enamel has solved the etching problem of long-term use; The medium circulation water inlet pipe reaches the heat exchanger bottom, in the middle of heat exchanger, is provided with horizontal baffle, has strengthened the circulation area of medium, has solved the excessive problem of water tank end and middle portion temperature difference and the little defect of common built-in heat exchanger heat exchange area.

This novel heat collector is to insert U-shaped pipe in ordinary vacuum tube, the outer alclad type fin of U-shaped pipe heat pipe, and aluminium type fin contacts with the vacuum tube inwall, plays the effect of transferring heat.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 series collector system can be realized indirect heat exchange, bearing operation, and water quality is much cleaner, and bombing is without leakage, and system is the most stable, longest-lived, and the thermal efficiency is higher.In vacuum tube, do not leak water, so also non flouling behaviour, the long-term use also can not affect the efficiency of its thermal-arrest.The damaged operational effect of its complete machine that also can not affect appears in vacuum tube, and this system adopts is the connection of rigidity, but pressure-bearing, can be by bring without silica gel sealing ring aging and the problem of revealing.
