A kind of balcony wall-hanging solar hot-water heating system
Technical field
The utility model relates to a kind of balcony wall-hanging solar hot-water heating system, especially a kind of split type balcony wall-hanging solar hot-water heating system.
Background technology
The critical piece of split type balcony wall-hanging solar hot-water heating system has heat collector, water tank, connection pipeline and controller.Flow circuit mode branch from hot-water heating system water is divided into natural recirculating type, forced cyclic type again.In the natural cycle system; Have only when the total head of circulating line loss during, could keep system water to circulate less than the effect pressure head of the circulatory system, so to the configuration of the difference in height between water tank and the heat collector, system pipeline; Even the shape of water tank all has certain requirement, brings many inconvenience to installation; Forced circulation needs water pump is installed in circulating line, has increased the consumption of electric energy, and this circulating pump just circulates should have the temperature difference at the water in solar heat collector and the water tank time, and need installation and control device has increased equipment cost and maintenance cost.And the heat collector of wall-hung solar water system adopts vacuum tube collector or heat pipe vacuum tube hot collector more; The advantage of this type heat collector is that the overall heat loss coefficient is little, and shortcoming is that floor space is big, obtain the same heat that gets; It is big many that the shared area of heat collector is wanted, and this is a fatal weakness as far as the wall-hung solar water system; Especially on national urbanization road for development from now on, little high level and skyscraper will get more and more, and because China is populous; Medium and miniature flat will be as main house type, and it is very limited that every household can be used to place the balcony wall area of wall hanging water heater heat collector.Therefore, how to improve the efficient of the Btu utilization of split type balcony wall-hanging solar hot-water heating system, become the problem of industry primary study.
Summary of the invention
The balcony wall-hanging solar hot-water heating system of the utility model has solved an above-mentioned difficult problem, has realized the Natural Circulation of split type balcony wall-hanging solar hot-water heating system simply and easily, and has the good heat transfer effect again.
The technical scheme of the utility model provides a kind of balcony wall-hanging solar hot-water heating system; Comprise the water tank that the installation site sets gradually from high to low, connect pipeline and heat collector, it is characterized in that: said water tank tank wall is an interlayer; Be provided with heat-transfer working medium in it; Said connection pipeline one end connects said water tank interlayer, and the other end connects said heat collector, makes heat-transfer working medium mutual conduction in said heat collector and the water tank interlayer.
Preferably, said heat collector is a flat plate collector, and the sender property outlet of said flat plate collector is communicated with said water tank interlayer through the said pipeline that is connected respectively with the working medium import.
Preferably, be provided with implementation of port and exhaust outlet on the said water tank external box wall.
Preferably, be provided with water inlet pipe and outlet pipe at the bottom of the said water tank case.
Preferably, said connection pipeline is a metal bellows.
Preferably, the outer wall of said metal bellows is coated with insulation material.
The balcony wall-hanging solar hot-water heating system of the utility model adopts the interlayer water tank as the thermal-arrest water tank, and water tank is installed in the top; Heat collector is installed in the water tank below; Metal bellows links to each other both, adopts the Natural Circulation mechanism of heat-transfer working medium, and the water in the water tank is heated; Thereby the Btu utilization effect is provided greatly, and has had benefit simple in structure, that cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model balcony wall-hanging solar hot-water heating system.
The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
As shown in Figure 1, the balcony wall-hanging solar hot-water heating system of the utility model comprises the water tank 1 that the installation site sets gradually from high to low, connects pipeline 2 and heat collector 3.Wherein the water tank tank wall is an interlayer, is provided with heat-transfer working medium 4 in the tank wall interlayer, and water tank external box wall upper end is provided with implementation of port 5 and exhaust outlet 6, is provided with water inlet pipe 7 and outlet pipe 8 at the bottom of the case.Connecting pipeline 2 is metal bellows; Can be coated with insulation material (not shown) for improving insulation effect tube connector pipeline outer wall; Connect pipeline 2 one ends and connect the water tank interlayer, the other end connects heat collector, makes heat-transfer working medium mutual conduction in heat collector and the water tank interlayer.
Preferably, heat collector 3 is a flat plate collector, and the sender property outlet 9 of flat plate collector is communicated with the water tank interlayer through being connected pipeline respectively with working medium import 10.
The balcony wall-hanging solar hot-water heating system of the utility model is at the water tank of installing successively from high to low 1; After connecting pipeline 2 and heat collector 3; Open water tank external box wall upper end and be provided with implementation of port 5 and exhaust outlet 6, in interlayer, charge into heat-transfer working medium 4, be full of rear enclosed implementation of port 5 and exhaust outlet 6.Connect water inlet pipe 7 and outlet pipe 8, and in water tank, be full of water 11.During use, flat plate collector 3 is the heat-transfer working medium in the heating heat collector runner after solar light irradiation absorbs heat, produces density contrast after heat-transfer working medium is heated; The heat-transfer working medium of heat rises; Cold heat-transfer working medium descends, and the heat-transfer working medium of heat rises in the water tank interlayer through the connection pipeline of sender property outlet 9, with the water in the heat transferred inner water tank; Cold heat-transfer working medium is back in the heat collector through the connection pipeline of working medium import 10; So repeatedly, continuously with the water in the heat transferred inner water tank, to reach the purpose that adds hot water.
Above embodiment is merely the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
