Description
Technical field
The utility model relates to a kind of heating plant, particularly self-loopa pressure-bearing type flat panel solar heat collecting system.
Background technology
At present; Vacuum glass tubular type solar water heater is very universal, has obtained numerous consumers' approval, still; It is impacted and is prone to cracked or lack of water or forget can cause defectives such as glass tube is cracked when moisturizing adds water again, becomes the inevitable defective of vacuum glass tubular type solar water heater.Though and split type flat plate solar water heater has remedied the deficiency of simple glass pipe type solar energy water heater, cost is very high to have restricted using and popularizing of consumer, and all there is the incrusted problem of long-term use in above-mentioned two kinds of solar water heaters.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and a kind of production, use cost is low, antifreeze and impact resistance is effective self-loopa pressure-bearing type flat panel solar heat collecting system are provided.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of self-loopa pressure-bearing type flat panel solar heat collecting system; Comprise solar thermal collector and the heat storage water tank that links to each other with solar thermal collector; It is characterized in that above-mentioned solar thermal collector is made up of with the heat dump that is installed in the casing the casing of sealing, the rear portion in the casing of sealing is equipped with the heat-insulation layer of being with reflectance coating, and the sensitive surface of casing is equipped with transparent glass; Above-mentioned heat storage water tank is made up of expansion tank and heating water tank, and heat exchanger is installed in heating water tank, and water inlet and delivery port are installed on heating water tank; The inlet of expansion tank links to each other with the liquid outlet of solar thermal collector, and the liquid outlet of expansion tank links to each other with the inlet of heat exchanger, and the heat exchanger liquid outlet links to each other with the feed liquor of solar thermal collector.
Above-mentioned transparent glass surface is pasted with transparent crashproof insulation film.
Above-mentioned heat dump is made up of the metal tube that the surface scribbles black absorbing material.
Above-mentioned heat exchanger is a spiral coil.
The heat transfer medium of adorning in the above-mentioned closed system of being made up of the heat dump in expansion tank, heat exchanger and the solar thermal collector is an anti-icing fluid.
Safety valve and heat transfer medium filler are installed on above-mentioned expansion tank.
The characteristics of the utility model: 1, solar thermal collector and heat storage water tank are divided into two autonomous systems; In the closed system of forming by the heat dump in expansion tank, heat exchanger and the solar thermal collector; Adopt anti-icing fluid as heat transfer medium; Improve heat transference efficiency on the one hand, solved antifreeze and scale problems on the other hand; The 3rd owing to above-mentioned heat absorption, heat release are closed system; Not only reduced the heat transfer medium evaporating loss; Make that also heat absorption, the heat release circulatory system become a pressure bearing system, heat medium temperature can surpass 100 degree, has improved the temperature of system; Guaranteed that also heat transfer medium can form closed circulation automatically, need not add circulation power.2, solar thermal collector has adopted the body structure of sealing; Can effectively reduce because the mobile heat that causes of air scatters and disappears; Be pasted with transparent crashproof insulation film simultaneously on the transparent glass surface, the bottom in casing is equipped with the heat-insulation layer of band reflectance coating, can increase endotherm area and improve heat absorption efficiency.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 cuts open enlarged diagram for the A-A of the utility model accompanying drawing 1.
The specific embodiment
Like Fig. 1, shown in 2; Solar thermal collector 1 is made up of with the heat dump 1-2 that is installed in the casing the casing 1-3 of sealing; Rear portion in the casing of sealing is equipped with the heat-insulation layer 1-1 of band reflectance coating; The sensitive surface of casing is equipped with transparent glass 1-4, and the transparent glass surface is pasted with transparent crashproof insulation film, and heat dump is made up of the metal tube that the surface scribbles black absorbing material.The transparent glass that sunlight sees through on the solar thermal collector heats heat dump; The anti-icing fluid that is contained in the heat dump is heated as heat transfer medium; Anti-icing fluid after being heated gets in the expansion tanks 4 through drain pipe 2, is got in the coupled heat exchanger of being made up of spiral coil 6 by expansion tank, through heat exchanger heating water tank 7 interior water is heated; Water after being heated is discharged by delivery port 8 and is used for life, and the water inlet of heating water tank is through water inlet 5 moisturizings.Anti-icing fluid through after heat exchanger 6 coolings returns heat dump through liquid back pipe 3.
For guaranteeing the expansion tank safe handling, safety valve 9 and heat transfer medium filler 10 are installed on expansion tank.
The heat transfer medium of adorning in the closed system of being made up of the heat dump 1-2 in expansion tank 4, heat exchanger 6 and the solar thermal collector 1 is an anti-icing fluid.
