Technical field
The utility model relates to photovoltaic field, relates in particular to a kind of photo voltaic hot water system.
Background technology
Photovoltaic module, also claims solar panel, is the core in solar power system, is also most important part in solar power system, and its effect is to convert solar energy into electrical energy, or is sent in battery and stores, or drives loaded work piece.At present, photovoltaic module on market, in absorbing luminous energy and the process in photovoltaic energy conversion, can produce higher heat, can make the especially temperature rising of backboard of whole photovoltaic module, thereby affect generating efficiency and the Q-percentile life of photovoltaic module, thus, photovoltaic module can install heat abstractor additional, thereby the heat producing when photovoltaic module is worked leaves, and this kind of mode not only increased manufacturing cost, and the heat energy of solar energy partly can not get effective utilization, has reduced solar energy utilization ratio.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of photo voltaic hot water system is provided, low to solve the solar energy composite utilization rate of existing photovoltaic module, need to install heat abstractor additional, has complex structure, the problem that manufacturing cost is high.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of photo voltaic hot water system, comprise photovoltaic collecting system, duplex matter system and water tank, described photovoltaic collecting system comprises photovoltaic module, collecting plate, heating tube and packaging back board, described photovoltaic module is platy structure, it comprises solar battery sheet, be fixed on the glass on solar battery sheet top and be fixed on the photovoltaic component back plate of solar battery sheet bottom, described collecting plate is made by aluminum, it is arranged at the lower surface of photovoltaic component back plate, on collecting plate, be provided with anodic oxide coating, described heating tube is coiled pipe, its tiling is arranged between collecting plate and packaging back board, described duplex matter system comprises circulation inlet pipe, recycle pipe, driving pump, described water tank is provided with heat exchanger, one end of described heat exchanger is connected with one end of heating tube by recycling pipe, the other end of heat exchanger is by circulation inlet pipe, driving pump is connected with the other end of heating tube.
As preferred version of the present utility model, described photovoltaic module, collecting plate, heating tube and packaging back board pressing connect.
The beneficial effects of the utility model are, described photo voltaic hot water system can effectively be utilized solar energy, being translated into electric energy uses, meanwhile, also can be by residual heat collection, for making the heating of water, both improved the utilization rate of solar energy, can save the heat abstractor of photovoltaic module again, secondly, by anodic oxide coating is set on collecting plate, make it have good endothermic effect, thereby the used heat of photovoltaic component back plate can be absorbed to the operating temperature that reduces photovoltaic module, improve the generating efficiency of photovoltaic module to solar energy, and heating tube adopts coiled pipe, heat absorption heat-transfer effect is good, further improved the utilization rate of the heat energy part of solar energy.

The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
Please refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the schematic diagram of a kind of photo voltaic hot water system of the utility model; Fig. 2 is the structural representation of the utility model photovoltaic collecting system.
In the present embodiment, a kind of photo voltaic hot water system, comprise photovoltaic collecting system 1, duplex matter system and water tank 5, described photovoltaic collecting system 1 comprises photovoltaic module 7, collecting plate 8, heating tube 9 and packaging back board 10, described photovoltaic module 7 is platy structure, it comprises solar battery sheet, be fixed on the glass on solar battery sheet top and be fixed on the photovoltaic component back plate of solar battery sheet bottom, described collecting plate 8 is made by aluminum, it is arranged at the lower surface of photovoltaic component back plate, on collecting plate 8, be provided with anodic oxide coating, described heating tube 9 is coiled pipe, its tiling is arranged between collecting plate 8 and packaging back board 10, described duplex matter system comprises circulation inlet pipe 3, recycle pipe 2, driving pump 4, described water tank 5 is provided with heat exchanger 6, one end of described heat exchanger 6 is connected with one end of heating tube 9 by recycling pipe 2, the other end of heat exchanger 6 is by circulation inlet pipe 3, driving pump 4 is connected with the other end of heating tube 9.
During work, photovoltaic module 7 absorbs solar energy and is converted into electric energy for use, the heat that photovoltaic module 7 produces in absorbing the process of luminous energy and photovoltaic energy conversion is absorbed by collecting plate 8, heat-transfer working medium in heating tube 9 between final and collecting plate 8, packaging back board 10 carries out heat exchange, heat-transfer working medium temperature is raise, by recycling, pipe 2 enters the heat exchanger 6 of water tank 5 to heat-transfer working medium after temperature raises and the water of water tank 5 carries out heat exchange, thereby the water in heating water tank 5 is for use.
The utility model can effectively utilize solar energy, being translated into electric energy uses, meanwhile, also can be by residual heat collection, for making the heating of water, both improved the utilization rate of solar energy, and can save again the heat abstractor of photovoltaic module, the setting of collecting plate 8 Anodic oxide layers can guarantee the effective insulation between photovoltaic module 7 and heating tube 9.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
