Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
A kind of solar energy collector system, as shown in Figure 1, described system comprises heat collector 1, storage heater 2 and radiator 3, valve 4, valve 5, valve 18, temperature sensor 6, described heat collector 1 is communicated with formation closed circuit with storage heater 2, heat collector 1 is communicated with formation closed circuit with radiator 3, the pipeline parallel connection at storage heater 2 and radiator 3 places, heat collector 1 absorbs solar energy, water in heating heat collector 1, water after heating enters respectively storage heater 2 and radiator 3 by outlet pipeline 8, in storage heater 2, carry out heat exchange, heat is stored in the heat-storing material of storage heater 2, in radiator 3, carry out heat exchange, the water flowing out in storage heater 2 and in radiator 3 carries out heat exchange in entering heat collector 1 through water return pipeline 17.
In said system, in carrying out accumulation of heat to storage heater, can utilize radiator outwards to dispel the heat by solar energy.Certainly, storage heater and radiator can independent operatings, or isolated operation one of them.
As shown in Figure 1, valve 4 is arranged on outlet pipe, for controlling the total water yield that enters storage heater 2 and radiator 3, valve 5 is arranged on the position of the inlet tube 16 of the pipeline at radiator 3 places, for controlling the flow of the water that enters radiator 3, valve 18 is arranged on the position of the inlet tube 7 of the pipeline at storage heater 2 places, for controlling the flow of the water that enters storage heater 2, temperature sensor 6 is arranged on the position of the entrance of radiator 3, for measuring the temperature of the water that enters radiator 3.Described system also comprises central controller, and described central controller carries out data with valve 4, valve 5, valve 18, temperature sensor 6 and is connected.
Preferably, the temperature of measuring when temperature sensor 6 is lower than certain temperature time, and central controller controls valve 5 strengthens aperture, and by-pass valve control 18 reduces aperture simultaneously, strengthens heat dissipation capacity with the flow that strengthens the hot water that enters radiator 3.The temperature of measuring when temperature sensor 6 is higher than certain temperature time, and central controller controls valve 5 reduces aperture, and by-pass valve control 18 strengthens aperture simultaneously, strengthens heat dissipation capacity with the flow that reduces the hot water that enters radiator 3.
The temperature measured when temperature sensor 6 is low to a certain extent time, the ability meeting variation of the now external heat exchange of radiator, cannot meet normal heating demand, this thermal-arrest ability that shows solar thermal collector also goes wrong, for example sunshine is not now very strong, or evening is not when thering is no the sun, now valve 4 can be closed automatically, valve 5 and valve 18 can be opened completely, the pipeline at storage heater and radiator place forms a circulation line, water enters in storage heater and absorbs the heat of storing in storage heater, and the water of heating enters in radiator 3 and dispels the heat.
By above-mentioned operation, can be when sunray be strong, in the heat-sinking capability that meets radiator 3, after meeting user's radiating requirements, unnecessary heat is stored by storage heater 2, the in the situation that of solar thermal collector 1 heat capacity deficiency, the heat in storage heater 2 is made full use of, to meet the radiating requirements of radiator 3.Can make full use of like this solar energy, avoid the waste of too much heat.
As preferably, can not utilize the temperature that enters the water in radiator 3 automatically to control the flow of water, can adopt the environment temperature of measuring radiator periphery, for example, the indoor temperature (by indoor temperature transmitter is set) of measuring radiator is controlled the flow of the water that enters radiator automatically, if indoor temperature is too low, increases the flow of the water that enters radiator 3, if indoor temperature is too high, reduce the flow of the water that enters radiator 3.
Certainly be that the temperature measured of temperature sensor 6 need to be higher than uniform temperature by a prerequisite of indoor temperature control flow, otherwise when the thermal-arrest ability variation of solar thermal collector, in any case increase flow, radiating effect can be not fine.
When the pipeline at storage heater and radiator place forms a circulation line, the temperature of measuring when temperature sensor 6 is lower than certain temperature time, central controller controls valve 5 strengthens aperture, by-pass valve control 18 strengthens aperture simultaneously, strengthens heat dissipation capacity with the flow that strengthens the hot water that enters radiator 3.The temperature of measuring when temperature sensor 6 is higher than certain temperature time, and central controller controls valve 5 reduces aperture, and by-pass valve control 18 reduces aperture simultaneously, strengthens heat dissipation capacity with the flow that reduces the hot water that enters radiator 3.The aperture of valve 5 and 15 is now consistent.
By such control, can rationally utilize the heat of storage heater, avoid the loss of heat.

Above-mentioned heat-storing material is the result obtaining by test of many times, has very high heat storage capacity, has met the absorbing heat in solar energy system running completely.
As preferably, set temperature sensor 19 on the outlet pipeline 8 of heat collector, for measuring the temperature of water outlet of heat collector, storage heater set temperature sensor (not shown) is for measuring the temperature of heat-storing material simultaneously.In the inlet tube 7 of storage heater, valve 18 is set, when valve 4 is opened, when the leaving water temperature of measuring is lower than the temperature of heat-storing material time, valve 18 is closed.When the leaving water temperature of measuring is higher than the temperature of heat-storing material time, valve 18 is opened.Avoid like this storage heater by heat at the water passing in water pipe, caused the loss of the heat in storage heater, to ensure that storage heater can store abundant heat.
Preferably, described radiator be finned tubular radiator, concrete structure is referring to Fig. 4.Finned tube comprises upper header 10 and lower collector pipe 10 and is positioned at the finned tube of lower collector pipe.Described finned tube is cylindricality finned tube, described finned tube comprises the cuboid 9 that is positioned at center and the fins set that is positioned at cuboid periphery, the cross section of described cuboid 9 is squares, from cross section, described fins set comprises from four outward extending main fins 11 in foursquare diagonal angle with from outward extending the first secondary fin 13 of main fin 11, described fins set also comprises outward extending the second secondary fin 12 from foursquare four limits, the first secondary fin 13 extending to same direction of described same main fin 11 is parallel to each other, and parallel to each other with the second secondary fin 12 extending to same direction, described main fin 11 and secondary fin 12, 13 ends of extending form equilateral octagon.
Preferably, as shown in Figure 3, the level crossing picture symmetry that finned tube forms along square diagonal, the plane that the while forms along the line at the mid point place of foursquare two opposite side is also mirror image symmetry.
