Abstract
The invention discloses an anti-freezing flat-plate solar collector and belongs to solar energy utilization devices. The anti-freezing flat-plate solar collector comprises an anti-freezing heat exchange medium filling and replenishing port, a heat exchange water pipe, a heat collection sleeve, anti-freezing heat exchange media, a framework, a heat collection pipe, a high transmittance glass panel and a heat collection plate core. A certain gap is reserved between the heat collection sleeve and the heat exchange water pipe, the heat collection sleeve is connected with the heat collection pipe, the anti-freezing heat exchange media are filled in a gap cavity and the heat collection pipe, and water absorbs heat of the anti-freezing heat exchange media when water passes the heat exchange water pipe so that temperature of water rises. By adopting the anti-freezing heat exchange media filled in the heat collection pipe, the defect that the flat-plate heat collector cannot adapt to low-temperature frozen zones is overcome, heat exchange direct temperature rising is fast, heat efficiency is high, and the solar heat utilization value is improved.
Description
Technical field
The present invention relates to a kind of solar energy heat utilization device, can solve the deficiency that the ordinary flat heat collector is not suitable with the icing area of low temperature, the direct quick heating of heat exchange, a kind of antifreeze flat-plate solar collector that the thermal efficiency is high.
Background technology
Solar energy is complied with the energy and the environmental protection policy of China as a kind of environmental protection regenerative resource, day by day comes into one's own.Add the global energy crisis that day by day manifests, further accelerated the development speed of solar energy related industry.With fastest developing speed in current solar energy utilization is solar water heater, and the important component part solar thermal collector of solar water heater is having two types at present: flat-plate solar collector, tube type solar collector.Flat-plate solar collector heat absorption efficient is high, service time is long and can be can perfect adaptation integrated with building, makes solar water heater also adapt to use at city multilayer and skyscraper.
Because the large ordinary flat solar thermal collector of China's various places vast in territory temperature difference is in the low area that freezes of temperature, the easy icing effect of thermal-collecting tube uses.
At present existingly solve antifreeze technology and the patent of flat-plate solar collector, but adopt water directly can prevent that again the flat-plate solar collector that thermal-collecting tube freezes from not yet finding to apply for a patent to the water heating by heat collector heat exchange water pipe.Below listing is technology and the Patents of having used:
Technical elements (mainly being to use in large-scale hot water engineering project): adopt the antifreeze heat transferring medium of in thermal-collecting tube, annotating to utilize dynamical system to carry out heat exchange by external dedicated heat exchanger and water water is heated.
(application number: 201110260791.8) propose a kind of antifreeze flat plate solar water heater, heat exchange coil is positioned at attemperater to patent " antifreeze flat plate solar water heater ", and heat exchange coil is connected with thermal-collecting tube, is filled with heat-exchange working medium in the pipe.
Summary of the invention
The invention provides a kind of antifreeze flat-plate solar collector.Take full advantage of environmental protection renewable energy solar energy and produce hot water.
A kind of antifreeze flat-plate solar collector comprises antifreeze heat transferring medium filling replenishing port, heat exchange water pipe, thermal-arrest sleeve pipe, antifreeze heat transferring medium, framework, thermal-collecting tube, high transparent glass panel, heat-collecting plate core.
The Main Function of described antifreeze heat transferring medium filling replenishing port is that antifreeze heat transferring medium is injected in thermal-arrest sleeve pipe and the thermal-collecting tube, and heat collector can replenish when using the antifreeze heat transferring medium of certain time limit lossy.
The Main Function of described heat exchange water pipe is the heat that water absorbs antifreeze heat transferring medium conduction in the thermal-arrest sleeve pipe during by the heat exchange water pipe.
The welding of the mouth of pipe of described thermal-arrest sleeve pipe and heat exchange water pipe makes the gap between two pipes form a cavity, is full of medium parcel heat exchange water pipe in the cavity and is connected with thermal-collecting tube, and Main Function is to make heat transferring medium directly conduct heat to the heat exchange water pipe.
What described antifreeze heat transferring medium adopted is that the low liquid of point pole is solidified in nontoxic nothing corrosion.
The Main Function of described framework is heat collector to be combined into an integral body include framework, heat-insulation layer, base plate.
It is that heat-collecting plate core receives and shines upon heat and conduct to heat transferring medium that described thermal-collecting tube and heat-collecting plate core weld Main Function mutually.
The invention has the beneficial effects as follows:
Antifreeze heat transferring medium in the thermal-collecting tube has solved flat plate collector and has been not suitable with the freeze deficiency in area of low temperature, and the direct quick heating of heat exchange, the thermal efficiency are high, have improved solar thermal utilization value; Production and processing simply improves just energy large-scale production a little in existing flat-plate solar collector manufacturer; Use corollary equipments such as getting final product flexibly monolithic increase water tank to use water heater can make things convenient for again large tracts of land to make up large-scale hot water engineering as family; External dedicated heat exchanger and supporting power set or heat exchange coil material have been reduced during the low use of investment operating cost.
Description of drawings
Accompanying drawing is antifreeze flat-plate solar collector structural representation.
Component names shown in the attached number in the figure: 1 antifreeze heat transferring medium filling replenishing port, 2 heat exchange water pipes, 3 thermal-arrest sleeve pipes, 4 antifreeze heat transferring mediums, 5 frameworks, 6 thermal-collecting tubes, 7 high transparent glass panels, 8 heat-collecting plate cores.
The specific embodiment
In the drawings: the solar energy that heat-collecting plate core 8 receives by high transparent glass panel 7, solar energy is converted to thermal energy conduction to thermal-collecting tube 6, thermal-collecting tube 6 interior antifreeze heat transferring mediums 4 absorb heats and conduct to heat exchange water pipe 2, and water temperature raise when water passed through the heat exchange water pipe 2 with heat.
