Split type photo-electric control solar water heater

The utility model relates to a kind of split type photo-electric control solar water heater, is specially adapted to family, collective's hot-water supply and auxiliary heating system.

Over nearly one, 20 year, the Application of Solar Energy technology has obtained tremendous development, especially solar water heater is various in style especially, from dull and stereotyped closing-sunning type to vacuum pipe solar water heater in recent years, mostly adopt static atural beat circulation to adopt hot mode and absorb solar energy, thermal-arrest and the hot global design of storage are installed in outdoor use.All these water heaters all exist volume big, install and use inconvenience, it is low to adopt the thermal efficiency, range of application is little, especially winter, cold district used, heat insulation effect is poor, easily causes bursting by freezing and damage.

The purpose of this utility model is on the basis of existing solar water heater, and a kind of light is provided---the solar water heater of the split type arrangement of electricity conversion automaton, thus make installations, use convenient, the heat absorption efficiency height, purposes is more extensive.

For achieving the above object, the technical solution of the utility model is: photovoltaic cell module 2 absorbs sunshine and converts electric energy to, power to D. C. pump 14 by lead-out terminal 4, D. C. pump 14 is pumped into the water of cistern in the heat collector 1 along upper hose 10, flow back to cistern 18 by downcomer 12 then, form thermal cycle.To battery 27 chargings, battery 27 is connected in parallel with temperature sensor 23, temperature indicator 28 and level sensor 24, water level display instrument 29 respectively photovoltaic cell module 2, forms water temperature, level displaying device by charging regulator 26 simultaneously.

In order to realize above-mentioned solution better, can do further improvement:

1, the input of the D. C. pump 14 in the link circuit of lead-out terminal 4 and the D. C. pump 14 adjustable resistance R of connecting.Adjust the resistance of adjustable resistance R, change the output voltage values of photovoltaic cell module 2.

2, at the lead-out terminal 4 diode CR that connects with the input of charging protector 26, restriction battery 27 is to D. C. pump 14 discharges.

3, photovoltaic cell module 2 is combined by 1 series connection of photocell piece and parallel connection.

Because the utility model has adopted heat collector 1 and cistern 18 splits combination, by light---electric conversion control device, heat collector 1 and the exchange heat and the control device of cistern 18 are moved simultaneously, greatly improved collecting efficiency.Water temperature, water level display instrument instant playback temperature and water level situation are used more convenient, safety.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model embodiment schematic diagram;

Fig. 2 is the utility model photo-electric control part line map.

The described solar water heater of Fig. 1 comprises heat collector 1 and cistern 18 two parts.Heat collector 1 is connected with downcomer 12 by upper hose 10 with cistern 18, forms water circulation system.Heat collector 1 is made up of thermal-arrest plate 5, circulation heat conduction pipe 6, water inlet 7 delivery ports 11, thermal insulation layer 9 and support 8.One side of heat collector installs photovoltaic cell module 2 additional.Cistern is made up of water return outlet 13, filling pipe end 15, steam vent 16, water supplement port 19, dewatering outlet 20, temperature indication 21, water level indication 22, battery compartment 25, heat-insulation layer 17 and the temperature sensor 23, level sensor 24, the D. C. pumps 14 that are installed in the cistern 18.

The light of the described solar water heater of Fig. 2---controller for electric consumption is made up of photocell piece 3, photovoltaic cell module 2, lead-out terminal 4, adjustment resistance R, D. C. pump 14, diode CR, charging protector 26, battery 27, temperature indicator 28, temperature sensor 23, water level display instrument 29, level sensor 24.Wherein photovoltaic cell module 3 is formed Light Electronic Control System by lead-out terminal 4 and adjustable resistance R, D. C. pump 14; Form charging circuit with diode CR, charging protector 26, battery 27.Battery 27 and temperature indicator 28, temperature sensor 23, water level display instrument 29, level sensor 24 are formed water temperature, level displaying device.

By the photo-electric control solar water heater that Fig. 1 and Fig. 2 form, its implementation process is as follows:

After sunlight heat is penetrated on heat collector 1 and photovoltaic cell module 2, and photovoltaic cell module 2 absorbs solar thermal energy, convert electric energy to, power to D. C. pump 14 by lead-out terminal 4.D. C. pump 14 is started working, water in the cistern 18 is sent into circulation heat conduction pipe 6 below the thermal-arrest plate 5 by the water inlet 7 of delivery port 15, upper hose 10, heat collector 1, water leans under the gravity effect along heat pipe 6, in heat pipe 6, do laterally back and forth to flow, after the heat absorption with the absorption of thermal-arrest plate, flow back in the cistern 18, so circulate by the following mouth of a river 11, downcomer 12, immediately the heat absorption that the thermal-arrest plate is absorbed is stored in the cistern.Simultaneously, to charge in batteries, charging protector 26 is adjusted the charge in batteries time to photovoltaic cell module 2 by lead-out terminal 4.

When sunshine disappear into or during the illuminance difference, photovoltaic cell module 2 absorbs solar energy to be reduced, after lead-out terminal 4 is not exported or output voltage do not reach effective operating voltage of D. C. pump 14, D. C. pump 14 quits work, thermal-arrest plate 5 is subjected to illumination effect, and it is low to absorb heat, and water cycle process stops immediately.In cistern, bursting by freezing takes place water in the heat collector 1 when preventing effectively that winter, cold district used by natural back flow under the gravity effect.At this moment, photovoltaic cell module 2 stops to charge in batteries, and to the display unit circuit supply, display unit shows cistern water temperature and water level situation by battery 27.

Better implement for the foregoing description, propose following corrective measure.
