The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Fig. 1 shows the structural representation of the embodiment one of solar-heating device of the present invention, and as can be seen from the figure, the solar-heating device of the present embodiment comprises heat supplying loop and pressure regulation circuit.Wherein, pressure regulation circuit links to each other with heat supplying loop, to regulate the pressure in the heat supplying loop.By pressure regulation circuit the pressure of heat supplying loop is regulated, can be made to keep suitable pressure in the heat supplying loop, overcome the resistance that pipeline brings to guarantee circulatory mediator circulation time in pipeline, guarantee the smooth and easy circulation of circulatory mediator in pipeline.
Above-mentioned heat supplying loop comprises heat collector 1 and safety valve 1a, and heat collector 1 has liquid outlet, liquid return hole and pressure relief opening, and wherein, safety valve 1a links to each other with pressure relief opening.It is that its temperature has larger variation with the fluctuating of external environment because of the parts of heat collector 1 as the collection heat in the heat supplying loop that pressure relief opening is opened on the heat collector 1, thereby so that the inside of heat collector 1 has larger pressure variation.When the pressure in the heat supplying loop exceeded the first predetermined value, circulatory mediator that can be from pressure relief opening and safety valve 1a ejection heat supplying loop was to reduce the force value of heat supplying loop.
Along with the rising of the pressure in the heat supplying loop, the boiling point of circulatory mediator also can be improved accordingly.When maintaining higher pressure in the heat supplying loop, the heat that the circulatory mediator portability is more, heat capacity and the heating efficiency of raising solar-heating device.Especially in the lower zone of air pressure, only make the normal use of the force value guarantee solar-heating device that keeps certain in the heat supplying loop.
Above-mentioned pressure regulation circuit has that the first pressure is regulated mouthful and second regulates mouthful, and first regulates and mouthful link to each other with pressure relief opening by safety valve 1a, and the second adjusting mouth links to each other with liquid return hole on the heat collector 1.Can enter into pressure regulation circuit from the circulatory mediator of pressure relief opening and safety valve 1a ejection.When the pressure in the heat supplying loop was lower than the second predetermined value, circulatory mediator regulates mouth by the second pressure and liquid return hole returns in the heat supplying loop, to promote the pressure in the heat supplying loop, made the pressure of heat supplying loop satisfy the demand that circulatory mediator moves.
Pressure regulation circuit comprises retracting device 11, fluid reservoir 12 and the pressuring pump 13 that connects successively.Wherein, retracting device 11 is used for collecting the circulatory mediator from safety valve 1a ejection, and these these circulatory mediators is stored in the fluid reservoir 12 in downstream.13 of pressuring pumps can be suppressed back the circulatory mediator of fluid reservoir 12 interior storages in the heat supplying loop, increase the pressure of heat supplying loop.Reflux for preventing that circulatory mediator produces in the process of suppressing, between pressuring pump 13 and the second pressure adjusting mouth, also be provided with check-valves 14, so that circulatory mediator can only carry out one-way flow.Between check-valves 14 and the second pressure adjusting mouth, also be provided with hand-operated valve 15, manually block the media flow in the pressure regulation circuit when with convenience pressure regulation circuit being overhauled.
For better controlling the pressure and temp in the heat supplying loop, on heat supplying loop, also be provided with pressure sensor 16, the solar-heating device includes the controller that all is electrically connected with pressure sensor 16, safety valve 1a and pressuring pump 13, real-time pressure value in the pressure sensor 16 monitoring heat supplying loop, and the real-time pressure value that records passes in the controller.Controller receive after the real-time pressure value can value and the first preset value and the second predetermined value compare.When the real-time pressure value is higher than the first preset value, the hypertonia in the expression heat supplying loop, controller control safety valve 1a opens, and by safety valve 1a the part circulatory mediator is discharged in the pressure regulation circuit.When the real-time pressure value is lower than the second preset value, the hypotony of expression heat supplying loop, controller starts pressuring pump 13 work, and the circulatory mediator in the fluid reservoir 12 is suppressed again in heating circuit, increases the pressure of heat supplying loop.
In embodiment one, heat supplying loop also comprises heat storage can 2 and fin 3 except heat collector 1, wherein, be provided with heating tube in the heat storage can 2, the first end of this heating tube is communicated with the liquid outlet of heat collector 1, the second end of heating tube and the liquid return hole of heat collector 1 are so that heat collector 1 can heat heat medium in the heat storage can 2 by heating tube.Fin 3 is in parallel with heat storage can 2, so that heat storage can 2 dispels the heat fin 3 by heat medium heating fin 3.
Fig. 2 shows the structural representation of the embodiment two of solar-heating device of the present invention, and as can be seen from the figure, embodiment 2 is the different of heat supplying loop from the difference of embodiment one.Implementing in two, heat collector 1, heat storage can 2 and fin 3 are in turn connected to form major loop.Outside major loop, the heat supplying loop of embodiment two also comprises at least one bypass loop, and the two ends of bypass loop link to each other with any one two ends in heat collector 1, fluid reservoir 12 and the fin 3.The circulatory mediator that is arranged so that of bypass channel can be dodged out the device that links to each other with bypass channel at circulation time, reduce thermal losses and the circulation timei of medium in cyclic process, to satisfy the thermal-arrest demand of solar heating system, improve the efficient of solar heating system.All the other mechanisms of embodiment two are identical with embodiment 1 with operation principle, do not repeat them here.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
