Specific implementation method
Shown in Figure 1; The utility model is made up of solar thermal collector A, storage tank B, controller C three parts.
Solar thermal collector A mainly is made of many straight-through type solar energy vacuum heat collecting tubes 1 and connector; Described connector comprises straight tube or L shaped pipe and U-shaped pipe 2, insulation material 3, and connector shell 4, colloid seal 5, water inlet pipe 6 and outlet pipe 7 are formed, and temperature-sensitive element 8 is housed in connector.Straight tube or L shaped pipe and U-shaped pipe 2, temperature-sensitive element 8 are formed one by insulation material 3 and connector shell 4 through foaming; The grafting of connecting with many solar vacuum heat-collecting pipes 1 of this assembly is with colloid seal 5 at each splicing position.
Solar thermal collector A is connected in series by many straight-through type solar energy vacuum heat collecting tubes 1, because the endothermic temperature of solar vacuum heat-collecting pipe can be higher than more than 200 ℃, so many pipe series connection back water progressively heat up when flowing in pipe and produce hot water.When hot water did not reach requiring of setting, water retained in thermal-collecting tube, can discharge hot water automatically when waiting to arrive design temperature.Thermal-arrest group A all uses with water inlet pipe 6 with water intaking valve 9, leaving water temperature control valve 10, exhaust-valve 11, safety valve 16, storage tank 14 and is connected with outlet pipe 7 usefulness running water pipes.
Storage tank B is that internal layer is that inner bag, middle level are insulation material, and skin is a shell body; It comprises water-level control apparatus 13, storage tank temperature sensor 15, storage tank air bleeding valve 17 and delivery port 18.Also can substitute or make with packing less attemperater according to user's needs otherwise designed, can be when substituting without air bleeding valve 17 with packing less attemperater.
Controller C comprises control device 12, flow of inlet water control valve 9, temperature-sensitive element 8, leaving water temperature control valve 10, exhaust-valve 11, the storage tank temperature sensor 15 that various electrical and electronic components are formed.These valves are connected with controller 12 by lead with the control signal of device.
Figure 2 shows that straight-through type solar energy vacuum heat collecting tube 1, it comprises through there being more than one metallic elements to be compounded in heat absorption rete 1-4 and outer glass pipe 1-1 on the inner glass tube 1-2.Inside and outside glass tube two ends are by sealing behind the vacuum 1-3 extraction air therebetween again.
Figure 3 shows that the ability that makes straight-through type solar energy vacuum heat collecting tube 1 improve hydraulic pressure resistance, at straight-through type solar energy vacuum heat collecting tube 1 endoporus whole metal straight pipe (1-5) is set again, and, on the outer wall of metal straight pipe, also be compounded with heat absorption rete (1-6) and fluid sealant spare (1-7) in order more to improve heat absorption capacity.
Fig. 4, the operation that Figure 5 shows that controller C and signal transmission schematic diagram; Civil power provides working power to controller and each by-pass valve control by terminals and lead, temperature-sensitive element 8 is connected in terminals by lead, it sends into the variable signal of sensing the control system of being made up of various electrical and electronic components, control system is according to the terminal installation of parameter of user with the signal triggering control apparatus, realized programming control automatically, and operation is made into the man-machine interface that numeral shows.
By above-mentioned accompanying drawing as can be known, cold water enters the thermal energy exchange that progressively heats up among the heat collector A, reach the temperature that the user sets after hot water flow out to storage tank B from outlet valve 10.The periodic duty process is: flow of inlet water control valve 9 was in closed condition before this, when the water inlet that places outdoor heat collector A progressively heated up by solar radiation to reach the user to set requires, thermal signal is delivered to indoor controller C through temperature-sensitive element 8, controller C triggers the circuit of flow of inlet water control valve 9 and it is opened, cold water enters heat collector A through heat exchange, when temperature rises to the leaving water temperature of user's setting, controller C opens them the air bleeding valve 17 in signal triggering leaving water temperature control valve 10 and the storage tank simultaneously, and hot water flows into storage tank 14 from outlet pipe 7 and uses for the user.When thermal-arrest group A temperature changed, the opening degree that controller 12 adjusts water control valve 10 automatically reached steady temperature.When the temperature of heat collector A was lower than the inflow temperature of setting, water inlet control valve 9 was closed, and exhaust-valve 11 is opened automatically, with the water emptying among the heat collector A, realized that heat energy all utilizes.When the water yield of storage tank B arrives set volume, by water-level control apparatus 13 signal is sent into controller C, controller C instruction triggers water intaking valve 9 and outlet valve 10 are closed automatically.When heat collector A internal gas pressure was elevated to certain pressure, safety valve 16 was opened automatically, steam is discharged guaranteed safety.So realized full-automatic loop control.
After safety valve 16 was opened automatically, the steam of being discharged can use steam for the user by be connected to the caisson of otherwise designed with pipeline.
Fig. 6-8 is depicted as scheme of installation: this serial solar energy water heater divides heat collector A, storage tank B and controller C three big sub-assemblies, is that water pipe is connected with lead between them.With reference to the accompanying drawings, can be that many solar vacuum heat-collecting pipes 1 are composed in series heat collector A in implementing use, be to increase hot water consumption heat collector A can also many groups go here and there or in parallel enforcement.Heat collector A can tile according to the situation in place, level or be hung on the body of wall and implement to install.Storage tank B can press direct proportion configuration volume according to the quantity of heat collector A; It is civilian to reach the not only suitable family of this utility model product, and adapts to the demand of large-scale groups such as each office, school, enterprises and institutions.
The utility model has mainly solved following problem: 1, by change the structure of solar vacuum heat-collecting pipe, again each vacuum heat collection pipe connected change heat exchange mode to reach the purpose that improves heat utilization efficiency; 2, utilize modern electronic technology to realize full-automatic intelligent control water inlet, water outlet and water temperature etc.; 3, solar thermal collector, storage tank, controller split setting connect again, can be installed on various buildings and the place, to satisfy the needs of multiple catergories of user; 4, when sunny, heat collector can produce steam and use for the user.
