Background technology
Solar energy is inexhaustible, the huge energy do not polluted.Along with the reserves of coal, oil, gas in the world reduce day by day, energy crisis is really put in face of people, and the use of traditional energy also threatens natural environment, destroys the ecological balance.Therefore solar energy has been considered the best environmental friendly regenerated energy.Along with the development of solar utilization technique, solar water heating system (water heater) also occurs thereupon, and becomes the significant energy conversion equipment of Solar use gradually.Because of it, there is the advantages such as life-span long, corrosion-resistant, fault is few at various solar water heating system (water heater) middle plateform solar water heater, progressively become the main flow of solar water heating system (water heater).
Solar water heating system (water heater) is all mounted in outdoor, under being directly exposed to the invasion and attack of wind and rain.China's most area has sub-zero weather to occur, under this weather condition, water in panel solar hot-water heating system (water heater) to rise bad circulating line due to icing volumetric expansion, causes hot-water heating system (water heater) to leak and cannot normally use.
So solar water heating system (water heater) in the market cannot directly use water to do circulatory mediator, only have the chemicals (anti-icing fluid) utilizing freezing point low to do circulatory mediator in system, use secondary heat exchange structure to solve the problem that in solar thermal collection system, pipeline freezes.This method has several large drawback:
The first, owing to using chuck or coil heat exchanger to carry out secondary heat exchange in heat storage water tank, compare direct heat transfer, thermal conversion efficiency is low, and product cost remains high.
The second, because the anti-icing fluid used is all chemicals (ethylene glycol, glycerine etc.), pipeline, once seepage is easily to environment, has very large injury once enter in water to human body.
3rd, anti-icing fluid is combined by chemicals and water, and temperature flowing can evaporate the water, cause and often need liquid feeding to ensure that system is normally run, make product follow-up maintenance difficulty, cost increase, and after Long-Time Service, antifreezing effect also can decline year by year and not reach antifreeze effect.
Summary of the invention

Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
See Fig. 1-2, for structural representation of the present utility model, there is provided a kind of anti-freezing type dull and stereotyped hot-water heating system, it comprises heat storage water tank 1, heat collector 4 and circulation line, heat collector 4 is connected with heat storage water tank 1 by circulation line, the comb 7 that heat collector 4 runner comprises upper header 5, lower collector pipe 6 and is arranged between upper header 5 and lower collector pipe 6, circulation line comprises cocycle pipeline 2 and lower circulation line 3, wherein upper header 5 is connected to the top of heat storage water tank 1 through cocycle pipeline 2, and lower collector pipe 6 is connected to the bottom of heat storage water tank 1 through lower circulation line 3.
Then cold water during work in heat storage water tank 1 enter into inside heat collector 4 comb 7 through lower circulation line 3 to lower collector pipe 6 due to the effect of gravity, after solar radiation heat transfer, water temperature raises rapidly, due to the reason of water density difference, water enters into inside heat collector 4 upper header 5 to floating, upper header 5 is got back to inside heat storage water tank 1 through cocycle pipeline 2 again, water inside heat storage water tank 1 is also because the reason of density contrast causes cold water in bottom, again because the effect of gravity enters inside lower circulation line 3, so repeatedly carry out circulation and water temperature can be made constantly to raise.When environment temperature is lower than zero degree, cocycle pipeline 2 and lower circulation line 3 are owing to having heat-barrier coating 10, and the water inside pipeline can not freeze, but heat collector 4 internal pipeline due to do not have heat-barrier coating often there will be pipeline freeze explosion problem.
The utility model improves heat collector 4 internal pipeline, several hollow silica gel balls 8 are set in upper header 5 and lower collector pipe 6, this silica gel ball 8 matter is soft and inside is filled with air, in comb 7, be provided with two ends sealing and the silica gel strip 9 of hollow simultaneously, there is gap so that current pass through between silica gel strip 9 and comb 7 inwall, the length of silica gel strip 9 and the length of comb 7 match and the two ends of silica gel strip 9 are fixed on comb 7 two ends, soft and the inside of same silica gel strip 9 matter is filled with the air of pressure, volume when the water freezing of heat collector 4 internal pipeline can be expanded to 1.1 times of water volume, air now in silica gel ball 8 and silica gel strip 9 is by cold events, ice cube extruding silica gel ball 8 in pipeline or silica gel strip 9 and can not extrusion pipe inwall, thus to pipeline, there is protective effect, when after temperature recovery water thawing, silica-gel sphere 8 or silica gel strip 9 return back to perisystolic state due to internal pressure and structural elasticity, water starts running system and normally runs, so repeatedly carry out reaching freeze proof object.
In addition, the inside of upper header 5 and lower collector pipe 6 is not suitable for adopting silica gel strip 9, because bar is known from experience affect current at pipe interior because the effect of gravity sinks to covering comb 7 outlet, freely hot property is low due to medium circulation directly to cause heat collector 4.
In order to optimize implementation result of the present utility model further, silica gel strip 9 is made to have enough hollow spaces, " ten " font reinforcement is provided with in the inside of silica gel strip 9, same silica gel ball 8 inside also can be arranged strengthens structure accordingly, preferably, silica gel strip 9 is 1: 1.7 with the diameter ratio of described comb 7.
In order to ensure the normal work of hot-water heating system, silica gel ball 8 should be able to flow with current and can not enter in comb 7 in upper header 5 or lower collector pipe 6, so the diameter of silica gel ball 8 is greater than the diameter of comb 7 and is less than the diameter of upper header 5 or lower collector pipe 6, preferred silica gel ball 8 is 1: 1.6 with the diameter ratio of upper header 5 or lower collector pipe 6.
In order to prevent the silica gel ball 8 in upper header 5 or lower collector pipe 6 from discharging with current, be fixed with square in the two ends radial direction of upper header 5 and lower collector pipe 6 inside, the aperture of this square is less than the diameter of silica gel ball 8 and can ensures that current pass through.
Above-mentioned example, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art person can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
