Solar water heater is accepted by people already as a kind of environmental type product, because its utilization is the solar energy of occurring in nature, can not cause any pollution to environment.What generally adopt in the prior art is direct insertion single cycle solar water heater, the incubator of this water heater and vacuum collector are directly to dress up one, incubator is horizontal being contained on the heat collector, so just causes bottom in incubator to have that partly cold water heating is very slow, the thermal efficiency is low.After some user always thought that in use running water comes out through vacuum collector in addition, water quality may change, and whether can cause some injury to health.Have for the low resident family of high floor, because aqueduct is longer, delivery can cause thermal loss bigger again.Adopt the single cycle solar water heater not only to have in use and retrained by the influence of weather, and on installing and keeping in repair, also will be subjected to environmental limit.
The purpose of this utility model is to propose a kind of simple and reasonable, two circulation electronic compensating solar water heaters that the scope of application is wide.
According to above-mentioned the purpose of this utility model, the water heater thermal cycle working method that we proposed is, adopts the mode of top water, and pressure that inner water tank bears is 3-6kg/cm
2, can connect a plurality of shower nozzles by a water tank, heating with making water is double circulation loop.Be described in detail with reference to the accompanying drawings below, with reference to the accompanying drawings 1,2 can find out, the two water heaters of the utility model are connected institute with heat collector 12 by pipeline by incubator 1 and form, the storage tank 2 of band storage tank water inlet 8 and storage tank delivery port 9 is housed in incubator 1, it is characterized in that the storage tank 2 bottom outer walls in perpendicular dress incubator 1 are set with circulation heating jacket 3, the upper port of circulation heating jacket 3 is connected with locating flange interface 7, be connected with heat collector delivery port 13 on the heat collector 12 by insulating tube at the circulation water inlet 4 on circulation heating jacket 3 tops, the circulating outlet 5 of circulation heating jacket 3 bottoms should join with the heat collector water inlet 14 of heat collector 12 lower ends.A heat-conducting medium mouth of a river 6 is installed on circulation heating jacket 3 and joins with thermal-arrest medium supplementary source, the height that the feature of this water heater is installed incubator 1 in addition should make circulating outlet 5 be higher than heat collector water inlet 13H 〉=200mm.Electrically heated rod 10 is equipped with in sealing in the storage tank 2 in incubator 1.
The operation principle of the utility model electronic compensating solar hot-water apparatus is to adopt frame mode that the closed circuit of water does not respectively communicate in the heat-conducting medium and incubator in the circulation heating interlayer cover.After heat collector is with the heat-conducting medium heating, utilize the density of liquid difference to form Natural Circulation, make the heat in the heat collector heat be passed to cold water in the incubator by heat-conducting medium flowing in the circulation heating jacket, after cold water temperature raises, density reduces to rise, density big cold water in next door then descends additional, and the water in the final incubator is finished the heat cycles of running water all by the hot circulating medium of heat collector conduction heating.Each does not communicate such two closed circuits, has guaranteed that water quality does not change, both can bathing, and hot water is used in life can to wash dish again, wash clothes etc., and the user can relievedly use.When bad weather, also can connect power supply, by running water in the electrical bar compensation heater incubator.In addition, because incubator is installed among the own home, promptly reduced the thermal efficiency that the pipeline of very long (high floor hang down resident family) causes and lost, having reduced very again, long pipeline brings unnecessary waste to the user, winter, pipeline also was difficult for enduring cold, and had removed the worry of worrying can not use winter hot water from.
It is simple, reasonable in design that the utility model electronic compensating solar water heater compared with prior art has an apparatus structure, easy for installation, the reliable and economic dispatch characteristics of working service.Both saved the thermal efficiency loss that long pipeline causes very much technically, and reduced material cost again, and this thermal-arrest mode is convenient to balcony again and installs very much, time saving and energy saving, easy to maintenance, and can be subjected to the influence of weather.
Description of drawings: in the specification of the utility model electronic compensating solar hot-water apparatus, accompanying drawing 1 is the syndeton generalized section of the utility model device, and accompanying drawing 2 is the cross-sectional view of incubator in this device.In accompanying drawing 1,1 incubator, 2 storage tanks, 3 circulation heating jackets, 4 circulation water inlets, 5 circulating outlets, the 6 heat-conducting medium mouths of a river, 7 locating flange interfaces, 8 storage tank water inlets, 9 storage tank delivery ports, 10 electrically heated rods, 11 heat-insulation layers, 12 heat collectors, 13 heat collector delivery ports, 14 heat collector water inlets.
