Description
The utility model relates to a kind of freeze-proof pressure-bearing glass vacuum pipe heat collector, belongs to the solar energy utilization technique field.
All-glass solar vacuum tubular collector is the advanced technology in the present solar energy optical-thermal transformation technology, compares with flat-plate solar heat collector, and its evenly heat efficient height, glass is corrosion-resistant, long service life; Influenced by ambient temperature very little, full glass vacuum tube solar water heater is energy-conservation, convenient, practical, be popular in users, and it is essential to have become people's daily life institute.But the subject matter that exists is to reach-30~-50 ℃ winter in the north than cold district, especially meets continuous many days rainy weathers, easily makes the all-glass vacuum tube bursting by freezing; The means to prevent freezing that adopts mainly is to establish corrective measure on water tank water-in and water-out pipeline at present, and winter, night was the water emptying in the water pipe when cold, but the just local water pipe anti-freezing problem that solves; Be that electric heating tube is installed in water tank in addition, to the water heating of water tank.The former can only solve winter is not terribly cold regional antifreeze problem; The latter still needs to use the energy.Another problem that exists is that heat collector bears the hydraulic pressure ability; Yielding, even influence the use of all-glass solar vacuum tubular collector, through domestic patent retrieval, existing people is studying the problem of this respect, as; Chinese patent is disclosed on July 16th, 1997, the applying date: on July 30th, 1996, applicant: Solar Energy Electronic Factory of Qinghua Univ., Beijing, application number: 96109027.8, utility model title: pressure-bearing type whole glass vacuum tube solar energy energy heat collector, the technical essential of the utility model purpose is to adopt the pressure-bearing type connecting pipe, the bending resistance tailstock, add supporting member along all glass vacuum heat collection tube of solar energy direction, the utility model has the advantages that and to bear 3.5-4.5 atmospheric tap water pressure, can constitute pressure-bearing type whole glass solar energy (opening) hydrophone and hot-water supply system, easy to use, bearing capacity increases, but still lower, and structure is complicated, the cost height still can not solve freeze proof problem simultaneously.
The purpose of this utility model just is to overcome the deficiencies in the prior art, but provide a kind of simple in structure, low single-stage of cost or multistage connection in series-parallel to use, installation and maintenance are convenient, freeze proof effective, do not freeze at-30~-50 ℃, bearing capacity is enhanced to the above freeze-proof pressure-bearing glass vacuum pipe heat collector of 12 atmospheric pressure.
The purpose of this utility model realizes in the following way:

Fig. 1-the 4th, the most preferred embodiment of the utility model freeze-proof pressure-bearing glass vacuum pipe heat collector is among the figure: 7 times tube connectors of tube connector 6 supports, 8,12 shells, 9,13 heat-insulation layers, 10 vent valves, 11 anti-icing fluid, 14 heat exchanger tube 15U shape tube connectors, 16 tank bodies, 17 little water pump 18 micropumps 19 water tanks on 1 tailstock, 2 all-glass vacuum thermal-collecting tubes, 3 connecting pipes, 4 heat exchange box 5.Below in conjunction with accompanying drawing freeze-proof pressure-bearing glass vacuum pipe heat collector of the present utility model is described in further detail:
As described in Figure 2, the connecting pipe 3 of the utility model freeze-proof pressure-bearing glass vacuum pipe heat collector and heat exchange box 4 inner bag Metal Material Weldings, shell is riveted with metal material, insulation material 9,13 is between inner bag and shell, heat exchanger tube 14 adopts the metallic plate of wall thickness 0.5-5mm to make, and anti-icing fluid 11 joins in heat exchange box 4 and the connecting pipe 3 by tank body 16.When single-stage was used, heat exchange box 4 was as shown in Figure 1 by last pipeline 5, pipeline 7 connects and is fixed in the shade of connecting pipe 3 down, and heat exchanger tube 14 two ends link to each other with water tank by pipeline.Shown in Fig. 2,3, because heat exchange box 4 pipeline 5 to the convection current of connecting pipe 3, following pipeline 7 is to be provided with to low by height, so but the heat energy folk prescription is to heat exchange box 4 convection current in the connecting pipe 3, and heat energy can not be oppositely to flowing to connecting pipe 3 in the heat exchange box 4.Connecting pipe 3, heat exchange box 4 has heat-insulation layer, is full of anti-icing fluid 11 in the inner bag, can not freeze; Also have to the connecting line of large water tank 19 and to be incubated measure preferably, so when night and successive cloudy days, for preventing that water freezing is opened micro pump 18 in heat exchanger tube 14 and the connecting line, during forced circulation, the heat energy dissipation amount is very little, has guaranteed northern cold season in winter, when temperature is very low, heat collector can normally move during such as-30~-50 ℃, has effectively prevented the damage of all-glass solar vacuum tubular collector; In addition, run through heat exchange box 4 in heat exchange box 4 heat exchanger tube 14 is set, heat exchanger tube 14 is because internal diameter is less relatively, and bearing capacity is strong, can bear the atmospheric pressure more than 12, make all-glass solar vacuum tubular collector can be suitable for the higher countries and regions of hydraulic pressure and use.
When the multistage string of need and company's large tracts of land use, as shown in Figure 3, by pipeline connecting pipe 3 is cascaded, heat exchange box 4 can be one-level lengthening case or plural serial stage case, many again groups are in parallel, connect little water pump 17 and micropump 18 parallel with one another by pipeline in the loop, link to each other with water tank 19 again, when being arranged, opens sunlight little water pump 17, the sunlight heat energy folk prescription that anti-icing fluid can thermal-collecting tube collects whole glass vacuum tube solar energy in the connecting pipe 3 is to flowing to anti-icing fluid in the heat exchange box 4, run through that water will be heated in the heat exchanger tube 14 of heat exchange box 4, to large water tank 19, water is heated water in the large water tank 19 by little water pump 17 forced circulation.The hypothesis environment temperature is extremely low when night or successive cloudy days, during such as-30~-50 ℃ in the connecting pipe 3 owing to be full of anti-icing fluid, be not afraid of icing, water does not freeze in the heat exchanger tube that runs through heat exchange box in order to make, by water (being higher than 0 ℃) forced circulation in the micropump 18 of design and installation in pipeline and the large water tank 19, water in the large water tank 19 is because thermal capacity is very big is difficult for dropping to 0 ℃, and in particular cases, the also reliable technique known of water is kept certain temperature by electrical heating and do not frozen in the large water tank 19.
Heat exchange box 4 is vertical with the roof when placing, and as shown in Figure 4, heat exchange box 4 should be higher than connecting pipe 3, and heat exchange box to 5 times pipelines 7 of last pipeline of tube connector all are provided with from high to low.
The heat exchanger tube 14 that is arranged in the heat exchange box 4 can adopt pipe or square tube or bellows etc.
Heat exchanger tube 14 surfaces can be provided with the heat exchange fin.
Heat exchange box 4 leans on shape for circle or rib is leant on shape.
