The specific embodiment
Embodiment 1, present embodiment such as Fig. 1-and shown in Figure 4, blade 17 is made up of tube connector 18, band finned tube thermal-arrest bar 19, transparency cover 20, insulation material 21, incubation chamber 22.Lay insulation material 21 in the incubation chamber 22, band finned tube thermal-arrest bar is arranged on above the insulation material, covers with transparency cover 20 on the incubation chamber, and the two ends of band finned tube thermal-arrest bar are connected to tube connector 18 respectively.The tube connector 18 at blade two ends is connected to form the shutter heat collector by articulation 16 and collecting pipe 11.Because connect with articulation, the inclination angle of blade 17 can be regulated easily.In the upper end of collecting pipe 11 negative-pressure balancing valve 10 is set, malleation safety valve 6 is set below collecting pipe 11.Fixed support 5 is fixed on the wall, and the shutter heat collector is installed on the fixed support 5.Water tank 1 is installed in indoor, the installation site preferably is higher than the shutter heat collector, the delivery port of water tank 1 links to each other with hot water valve, and the delivery port of water tank 1 links to each other with the lower end of a collecting pipe 11 by check-valves 12, and cold water inlet 13 is connected on the pipeline between check-valves 12 and the collecting pipe 11.The upper end of another root collecting pipe 11 links to each other with the water inlet of water tank by circulating pump 2.
Outdoor pipeline and shutter heat collector lay accompanying-heat cable 14, and accompanying-heat cable joins with power supply by power switch 4 and power line 9.Outdoor pipeline covering and heat insulating layer 15.
The course of work is as follows, loosening articulation, and the inclination angle of adjusting vane makes solar incident angle the best, fastening then articulation.Open hot water valve 7, cold water enters from cold water inlet 13, and this moment, check-valves 12 ended.Cold water enters the shutter heat collector, injects water tank by pipeline, closes hot water valve when hot water outlet 8 there are flowing out.
When water tank 1 was higher than the shutter heat collector, water can be realized natural circulation heating, and the water in the shutter heat collector is heated by daylight, and hot water rises and enters water tank, and water in water tank decline enters the shutter heat collector from the below.The circulating path of water is the shutter heat collector, and------------water tank 1 exports---check-valves 12---collecting pipe 11 lower ends---shutter heat collector to water tank 1 inlet to circulating pump 2 to collecting pipe 11.But if quicken circulation ON cycle pump 2.
When water tank 1 was lower than the shutter heat collector, ON cycle pump 2 carried out forced circulation.
In the winter time, if outdoor temperature is lower than zero centigrade, power turn-on switch 4, accompanying-heat cable 14 heatings prevent to freeze.
Being provided with malleation safety valve 6 and negative-pressure balancing valve 10 makes the shutter heat collector have antifreezing function.Pressure increases in the volumetric expansion when water freezing, shutter heat collector, and when pressure reached certain limit, the malleation safety valve was opened the step-down that discharges water, and the interior pressure of shutter heat collector is remained in the safe scope, and the shutter heat collector can not damage because of freezing.Pressure is lower than atmospheric pressure in volume-diminished during ice-out, shutter heat collector, negative-pressure balancing valve 10 unlatchings this moment, and air enters in the heat collector, makes the inside and outside pressure equilibrium of shutter heat collector, and the shutter heat collector can not damage when ice-out.
When hot water valve 7 was opened, cold water entered from cold water inlet 13, and this moment, check-valves 12 ended.Cold water enters the shutter heat collector, enters water tank by pipeline, and the hot water in the water tank is ejected, and hot water flows out from hot water outlet.When hot water valve 7 is closed, check-valves 12 conductings, system is in Natural Circulation or forced circulation state.
Embodiment 2, and as Fig. 5-shown in Figure 7, band finned tube thermal-arrest bar 19 is arranged in the transparent vacuum pipe 23, and with end cap 24 sealings, the tube connector 18 at band finned tube thermal-arrest bar 19 two ends passes the end cap center and links to each other with articulation at the two ends of transparent vacuum pipe 23.Band finned tube in each vacuum tube is connected to form the shutter heat collector by articulation and collecting pipe.Other structures and the course of work are identical with vane type shutter anti-freezing solar water heater shown in Figure 1.
