Description
The utility model relates to solar energy heat utilization technical field, particularly a kind of cold-resistant solar water heater.
At present, common flat plate solar water heater is freezing for preventing, general only uses under temperature above zero, and the vacuum tubular glass solar collector can not be for a long time uses being lower than under the subzero 25 ℃ condition.Heat-tube vacuum tubular type solar water heater uses more than 25 ℃ subzero mostly.Present stage has only a few solar water heater to work below 25 ℃ subzero, but this solar water heater price height, the manufacture process requirement strictness is difficult to apply.
The purpose of this utility model is: at the problem that prior art exists, design provides a kind of simple in structure, and manufacturing process is simple, and cost is low, the efficient height, can be under subzero 40 ℃ temperature the cold-resistant solar water heater of operate as normal.
The utility model is achieved by following occurring mode: a kind of cold-resistant solar water heater, water tank 1 and pipe section thereof with a band heat-insulation layer 2, wherein, pipe section be arranged at water tank 1 one sides upper hose 12 and on check valve 10, breather pipe 17 and 11, magnetic valve 8, stop valve 15 and shower nozzle 14, and stop valve 13 and 16, feature of the present utility model is: be provided with capsule formula heat exchanger 3 in the water tank 1, on it, in go up and the bottom is respectively equipped with breather pipe 4, upper circular tube 5 reaches circulation pipe 6 down, and on, following the circulation pipe 5 and 6 top and the bottom joint of the heat-collecting box 7 below being arranged at capsule formula water heater 3 respectively is communicated with, as Fig. 1, shown in 2.Simultaneously, the measuring head 20 of water level display instrument 9 is set, as shown in Figure 1 in water tank 1.
Said capsule formula heat exchanger 3 is expandable casing, this casing can be a rectangle, it also can be other geometry, and this casing can adopt the metal material manufacturing, for example can adopt the sheet metal manufacturing, as copper coin, corrosion resistant plate, galvanized sheet etc., in addition, above-mentioned capsule formula heat exchanger 3 is expandable casing, the volume that capsule formula heat exchanger 3 is described is transformable, and promptly when the non freezing solution (anti-icing fluid) in the capsule formula heat exchanger 3 heated up, its volume also constantly expanded, increase, pressure in the heat exchanger 3 increases to some extent, because heat exchanger 3 is a capsule formula structure, and is made by sheet metal, so along with the rising of pressure, its volume is also increasing, and can hold non freezing solution by volume that temperature rise increased.
The course of work of the present utility model and principle are: after whole solar water heater installs, after at first in water tank 1, filling with water, then by annotating (putting) liquid valve 19 to capsule formula heat exchanger 3, heat collector 7 reaches, inject non freezing solution in the following circulation pipe 5 and 6, then close and run wind 18, after heat collector 7 is subjected to the solar light irradiation heat absorption, non freezing solution just is heated, when temperature is higher than fluid temperature in the heat exchanger 3, just begin circulation, by upper circular tube 5 inflow heat exchangers 3, carry out heat exchange with the water in the water tank 1, and not heated non freezing solution is just by circulation pipe 6 is additional down, after carrying out the non freezing solution cooling of heat exchange with water in the heat exchanger 3, enter heat collector 7 again by circulation pipe 6 down and absorb solar energy, and constantly flow in the water tanks 1 by upper circular tube 6, go round and begin again, non freezing solution and water temperature constantly rise, and its volume also constantly expanded when non freezing solution heated up, increase, the pressure in the heat exchanger 3 increases to some extent.But because the structure of heat exchanger 3 is the capsule formula, and made by metallic plate, so along with the rising of pressure, its volume is also increasing, can hold non freezing solution by volume that temperature rise increased, when using hot water, close stop valve 16, open magnetic valve 8, hot water is just from water tank 1 flow through magnetic valve 8, stop valve 15, by shower nozzle 14 ejections, control valve 13, the water temperature that can regulate ejection.During last water, valve 16,15 is closed, and magnetic valve 8 is opened, check valve 10 is closed, and shows water level by water level display instrument 9, when water is full of, valve-off 13 and magnetic valve 8, stop to go up water, open valve 16, top in the upper hose 8 is because the deadweight of water causes negative pressure, check valve 10 is opened, air is entered by breather pipe 11, and all emptyings of the water in the upper hose 8 are with anti-freeze.Do not freeze medium because of being low temperature in heat collector and the circulation pipe, therefore, even the temperature in winter in the time of subzero 40 ℃, water heater can not be damaged by frost yet.
Fig. 1 is a general structure front view of the present utility model.
Fig. 2 is a general structure side view of the present utility model.
Among the figure: (getting) water pipe, 13 stop valves, 14 shower nozzles, 15 stop valves, 16 stop valves, 17 breather pipes, 18 run wind, 19 and annotate (putting) liquid valves, 20 measuring heads on 1 water tank, 2 heat-insulation layers, 3 heat exchangers, 4 (heat exchanger) breather pipe, 5 upper circular tubes, 6 times circulation pipes, 7 heat collectors, 8 magnetic valves, 9 water level display instruments, 10 check valves, 11 breather pipes, 12.
