Described heat absorption water can circulate by the mode of unpowered free convection between described solar energy heat collector 200 and described heat-exchanging water tank 110, described heat exchange water flows in described heat exchange coil 101, and heated by the described heat absorption water circulated, carry out heat exchange with described heat absorption water.As shown in Figure 1, the intracavity inter-connection of the inner chamber of described solar energy heat collector 200 and the inner water tank 105 of described heat-exchanging water tank 110, heat absorption coolant-temperature gage in the inner chamber of described solar energy heat collector 200 raises rapidly after absorption solar energy, and water flow temperature in the inner chamber of the inner water tank 105 of described heat-exchanging water tank 110 is relatively low, thus convection current is formed, with liter waterborne, the current of lower temperature decline in the heat absorption of higher temperature, the heat of solar energy is brought near heat exchange coil 101, thus the heat exchange water lower with the temperature in heat exchange coil 101 carries out heat exchange.
The heat exchange coil 101 that described heat exchange water flows wherein is connected with water supply pipe by water inlet, and be connected with water device by delivery port, thus, described heat exchange water is driven by the natural water pressure of described running water, and flows in described heat exchange coil 101.The water supply pressure of the 4.0.5 Urban Water Distribution Pipe Network in China's " water supply engineering planning specification " should meet the requirement of user's take-over point place service head 28m.Namely 0.28MPa.The hydraulic pressure of general water heater starts scope at 0.02--0.6Mpa.Heat exchange coil 101 is connected in tap water pipe network by the pipeline that matches with municipal tap water pipe network and pipe joint, and the hydraulic pressure of running water is enough to promote the heat exchange water current in heat exchange coil.Certainly, for higher than the building roof of six layers, generally need power water pump that running water is promoted to tall building roof, this power water pump belongs to running water system, when not installation of modular solar water heater 300, need power water pump for providing running water higher than the resident of six layers, therefore, power water pump does not belong to modularization solar water heater 300 yet.
Described heat-exchanging water tank 110 comprises inner water tank 105, and wherein, inner water tank 105 carries out isothermal holding, reduces thermal loss.
The applicant is a kind of unpowered circulation instant heating solar water heater disclosed in patent document CN102607190A, it uses water collector to be in series connected after first for heat exchange coil parallel connection with water knockout drum, thus reaches the object of assembling expansion solar water heater capacity.
According to the detailed description of the invention of modularization solar water heater of the present utility model, the main design thought of inventor develops the technical scheme made new advances, and it does not use the such non-standard component of water collector and water knockout drum and realizes the technical purpose that heat exchange unit is directly connected with tap water pipe network.
For this reason, as Figure 1-4, described heat-exchanger rig also comprises titting water outlet 1021, admitting pipe joint 1022, outlet conduit 103 and inlet channel 104, and described titting water outlet 1021, admitting pipe joint 1022, outlet conduit 103 and inlet channel 104 are arranged in described inner water tank 105.Advantageously, titting water outlet 1021, admitting pipe joint 1022, outlet conduit 103 and inlet channel 104 can be industrial standard parts, and this effectively can reduce manufacturing cost.All these elements are all placed in described inner water tank 105, this not only makes modularization solar water heater 300 compact conformation, attractive in appearance, not messy, and what is more important, significantly can reduce a large amount of heat-energy losses under outlet conduit 103 and the external situation of inlet channel 104.Show after testing, the solar energy system efficiency of such modularization solar water heater 300 can reach 60%.

Domestic hot-water due to itself and direct body contact, and has a large amount of librarian use in this engineering.Therefore guaranteeing pure, the safety of domestic hot-water's water quality, is the primary condition that solar thermal collection system must meet.
Former concentrated solar thermal collection system scheme, has more than 4m in its huge constant temperature water tank 3hot water storage.A large amount of hot water stores for a long time in water tank, and first whether its water quality is qualified leaves a question open.In addition, due to the arrangement of having a holiday or vacation that school is annual, in the time period, water consumption is lower certainly will two even multiple---little long holidays---.
Foreign system is all closed system, in addition in order to water quality safety, have the automatic running program of a high temperature sterilization unpowered circulating solar energy hot-water heating system every month, the hot water that is long placed in stored in its system only uses as heating agent, and running water is by supplying user after the heat exchange of heat exchange coil instant heating.Adopt the heat exchange coil of 304 stainless steels, can bear the pressure of more than 1.0Mpa, ensure that domestic hot-water does not contact completely with heat medium water simultaneously, the instant heat of hot water, water quality is fresh, pollution-free.
6. heat collector prevents overheated safety
Solar energy, as a kind of regenerative resource, has obvious short slab: not enough when often needing, excessive on the contrary when not needing.Namely the most obvious example is that northern area solar irradiation in summer is strong, and domestic hot-water's calorific requirement is lower; Winter solar irradiation is on the low side, and domestic hot-water's calorific requirement is but the highest in 1 year.Therefore, any solar thermal collection system (is such as had a holiday or vacation period) under off-design behaviour in summer all can exist superheating phenomenon, the most serious for this problem of school.Overheatedly often cause in heat collector that temperature is more than 130 DEG C, enclosed pressure bearing system then can be even higher more than 160 DEG C, and direct acting result is exactly that heat collector damages (booster, burst, thermal-arrest pull-up falls).
Open type heat accumulation enclosed heat exchange that native system adopts design, then put only solar energy overheated in there is its advantageous advantage.First, in the Storage Unit that open type heat accumulation makes, heat medium water or heat absorption water directly communicate with air, as long as heat medium water does not have complete evaporate to dryness, then its internal temperature is never more than 100 DEG C.Secondly, limnimeter detects water level in Storage Unit automatically, after water level is lower than setting value, then opens solenoid valve supplements heat medium water, even if summer, school had a holiday or vacation period, domestic hot-water is completely unmanned to be used, in 60 days summer, each Storage Unit only needs moisturizing can meet evaporating loss (Beijing area measured data) for 2-3 time completely.Heat collector problems of excessive heat is also just readily solved naturally.
7. system is easy to safeguard
System is simple, control is simple, native system does not have complicated automatic control system, both constant temperature delivery water was not had, temperature difference thermal-arrest is not had to circulate yet, system collecting end of heat has benefited from its unpowered thermal-arrest cyclic design, can accomplish low maintenance, even non-maintaining, thus greatly reducing administrative staff's quantity (2-3 people manages a district), system simple and clear in addition also makes the staff of general education level be competent at maintenance work.
Data shows, 15 years operation total costs of unpowered circulating solar energy system are 60.5% of regular solar systems.And unpowered circulating solar energy system all has exclusive advantage in the problems such as chapter of making an uproar, water quality, hydraulic balance.No matter reducing discharging consumption reduction or in practical effect, be that other system cannot be compared.
