Abstract

The utility model provides a solar water heater which comprises a heat collector, a water storage box, an upper internal circulating connecting pipe, a lower internal circulating connecting pipe, an upper communicating pipe water supply (discharging) pipe connecting piece, a lower communicating pipe water supply (discharging) pipe connecting piece and a support. The utility model is mainly characterized in that the hollow plate heat collector and the water storage box are integrated together. The solar energy can be used directly to heat up the water in the cavity of the hollow plate heat collector. The water in the heat collector and the water storage box can generate convection through the upper internal circulating connecting pipe and the lower internal circulating connecting pipe for natural circulation, which achieves the goal for providing users hot water. The utility model has the advantages of compact structure, low cost in fabrication and using, none environment limit, convenient installation and high heat utilization of solar energy.

Description

Solar water heater

Affiliated technical field

The utility model relates to a kind of solar heat conversion equipment, especially a kind of solar water heater.

Background technology

The feature of environmental protection energy as a kind of cleaning, the current common concern that is subjected to people more and more of the development and utilization of solar energy, it is more wide that particularly solar water heater etc. is used for the production development prospect of people's life, but prior solar water heater is because the many deficiencies on technology and the project organization, solar energy utilization rate is not high, as: 1, existing solar water heater great majority adopt glass-vacuum tube, because the glass-vacuum tube manufacturing process technology is had relatively high expectations, manufacturing cost is also high, and easily break, need normal replacing glass-vacuum tube, thereby further strengthen practical cost; 2, on project organization, existing solar water heater all adopts the upper and lower setting of water storing tank and heat collector, water pipe ways of connecting, complex structure basically, bulky, the cost height, and poor stability is installed on skyscraper, make the utilization rate of overall efficiency and solar heat all lower.

Summary of the invention

The purpose of this utility model provides a kind of compact conformation, and simple structure is made, practical cost is low, can effectively utilize the incorporate box-type solar water heater of heat collection water storage of solar heat.

The purpose of this utility model is achieved through the following technical solutions: it is by heat collector, water storage box, on, following cross over pipe, on, circulation tube connector down, advancing (going out) water pipe connector and support forms, it is characterized in that heat collector and water storage box make one, described heat collector is the cored slab structure, by hollow aluminium alloy plate and last, following cross over pipe welding or bonding forming, establish several equidistant deep floors in order to increase mechanical strength at hollow aluminium alloy plate inner chamber, on the hollow aluminium alloy plate, in the lower, transverse setting, following cross over pipe one end by interior circulation tube connector respectively with water storage box on, the bottom is communicated with, circulation in becoming, the water storage box bottom is provided with into (going out) water pipe connector, on, the following cross over pipe other end is provided with the cleaning valve, so that clean the dirt in the heat collector at any time, water storage box top is provided with exhaust benefit stream pipe, heat-insulation layer is all arranged at around the water storage box and bottom, and heat collector is positive except that selective heat-sink shell.

When the sunshine direct projection when scribbling the heat collector of selective heat-absorbing layer, water at hollow slab type heat collector inner chamber heats up gradually, and under the effect of the temperature difference, utilize the Natural Circulation principle, by the water convection current in circulation tube connector in upper and lower and the water storage box, thus effective conversion of realization solar heat and the purpose of hot water is provided to the user.

The beneficial effects of the utility model are that it is compared with the tubular structure heat collector owing to adopted the heat collector of hollow slab type structure, and endotherm area is big, the solar energy utilization ratio height, on structural design, adopt heat collector and the incorporate technical scheme of water storage box, therefore, has compact conformation, at the bottom of the cost, it is convenient to install, and uses not to be subjected to environmental limitations, many characteristics such as physical life is long, and anti-time property is strong.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the figure: 1, heat collector; Cross over pipe on 2; 3, go up interior circulation tube connector; 4, exhaust benefit stream pipe; 5, water storage box; 6, heat-insulation layer; 7, support; 8, advance (going out) saliva pipe connections; 9, down interior circulation tube connector; 10, following cross over pipe; 11, cleaning valve; 12, deep floor.

As shown in the figure, on the heat collector (1), following two ends are respectively equipped with cross over pipe (2) and the second line of a couplet can be managed (10), and make one with water storage box (5), last cross over pipe (2), following cross over pipe (10) is communicated with the heat collector inner chamber, last cross over pipe (2) is communicated with water storage box (5) top by circulation tube connector (3) in last again, following cross over pipe (10) is communicated with water storage box (5) bottom by down interior circulation tube connector (19), one end of last cross over pipe (2) and following cross over pipe (10) is provided with the cleaning valve, exhaust benefit stream pipe (4) is located at water storage box (5) top, protects the water storage box (5) that encloses with the bottom with heat-insulation layer (6) all around and is supported by support (7).Hollow slab type heat collector (1) inner chamber is established several equidistant deep floors (12) as required.
