Abstract

The utility model relates to a solar water heater, which is a heat conversion tank provided with a wide mouth. The tank is divided into three-layer space, a water outlet pipe of the lower layer is provided with an insulating plate, finite space is left to be arranged a layer of heat absorption plate, and finite space is also left to be covered with a transparent thermal insulation cover. The sunlight passes through the cover to solarize the heat absorption plate to cause the temperature of the gas of the upper layer and the lower layer space of the heat absorption plate to be increased. The high-temperature gas rises to form natural circulation and carries out heating to a water pipe. The hot water in the pipe rises to form natural circulation to totally heat the water in a water storage tank.

Description

Two circulating solar energy water heaters

The utility model relates to a kind of solar converter, is a kind ofly with the hot-air Natural Circulation water to be heated.The solar water heater of gas, the two Natural Circulation of water.

The solar water heater that uses has at present: " vacuum tube heat absorbing Natural Circulation " and " aluminium sheet aluminum pipe heat absorption Natural Circulation " two big classes.These two kinds of styles are high-leveled and difficult to promote because of cost.

The purpose of this utility model provides a kind of simple in structure, and materials are few, and is durable of a specified duration, cheap solar water heater.

The purpose of this utility model is achieved in that thermal power transfer case and insulation water storage box separate.Heat converter is a rectangular incubator, places according to a head taller low dip of long direction, has wide-mouth above the case, and flap covers completely with transparent material, does not give gas leakage, leaks.Separate three layers in the case up and down, the bottom adjutage, the water pipe two ends are connected and are communicated with horizontal water pipe, laterally water pipe coexist a side pass case outer be incubated water storage box and be connected, water pipe leaves the space up and down in case, the thermal insulation board that upper cover one deck is made with heat-barrier material, this dividing plate left and right sides closely is connected with casing, and the certain space allowing air flow is left at the height two ends.Leave certain space on thermal insulation layer, the absorber plate of black is installed, this absorber plate left and right sides is connected with casing, and the height two ends will be left certain space and just cover transparent insulation cover.Sunlight sees through lid according to shining the gas heating of two sheaf spaces up and down that absorber plate makes absorber plate, high-temperature gas rises to the chest upper end and runs into cold water pipe, hot-air sinks down into the bottom along cold water pipe and forms Natural Circulation under the effect that there is a natural attraction between the sexes, water after water pipe is heated in the pipe expands and rises, horizontal water pipe through the upper end flows to water storage box, and the cold water in the water storage box flows back to the lower end of water heater through a delivery port, and water is the formation Natural Circulation in pipe, and water is all heated.When the sun sets or because of the temperature of the absorber plate that rains descends, air-flow recycled back in the case, water for cooling, when water temperature was lower than the temperature of water storage box in the pipe, just by the circulation voluntarily in case of short circuit pipeline, no longer through the water storage box circulation, the minimizing water tank was lowered the temperature in the circulation of water.

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

Fig. 1 is a cutaway view of the present utility model.

Fig. 2 is a left view of the present utility model.

Fig. 3 is a vertical view of the present utility model.

1 thermal power transfer case among the figure; 2 water pipes; 3 thermal insulation boards; 4 absorber plates; 5 transparent insulation covers; 6 steam vents; 7 delivery ports; 8 water inlets; 9 use water valve; The incubator of 10 water storage boxes; 11 water storage boxes; The insulation cover of 12 water storage boxes; 13 water intaking valves; 14 circulating outlets; 15 circulation water inlets.

In the embodiment shown in Fig. 1,2,3, the case face of thermal power transfer case 1 is wanted Souteern Exposure, have water inlet 8 for the upper end, spend to inclination of 50 degrees with 30 and to lay.Area, China north and south difference at sunshine, the maximum that as far as possible reach sun direct projection is advisable.The water storage box position will be a little more than the thermal power transfer case.Circulation water inlet 15 will be higher than delivery port 7, notices during connection that water pipe can not be crooked up and down, and preventing to manage internal memory has air.After water pipe is connected, from the water storage box water inlet, the chock plug of steam vent 6 is opened, preventing to manage internal memory has air.Again it is filled in after seeing steam vent 6 water outlets.Transparent insulation cover 5, sealing around will making during lid keeps raining in the water-tight inlet, and air does not circulate with the external world in the case.

Claims (1)

1, a kind of solar water heater, it is characterized in that: three sheaf spaces are separated in the inside at thermal power transfer case (1), and bottom adjutage (2) is installed thermal insulation board (3) on it, go up again absorber plate (4) is installed, the transparent insulation cover of case flap (5), sunlight sees through insulation cover, according to shining absorber plate, make absorber plate two sheaf space gas heatings up and down, form Natural Circulation, water is heated, hot water formation Natural Circulation all heats the water of water storage box.
