As shown in Figure 3, solar energy system, comprise collector system, described collector system comprises heat collector, heat collector comprises thermal-collecting tube 21, speculum 20 and collecting plate 22, connected by collecting plate 22 between two adjacent thermal-collecting tubes 21, thus make to form tube plate structure between multiple thermal-collecting tube 21 and adjacent collecting plate 22; Described solar energy collector system comprises two pieces of tube plate structures, shape a at a certain angle between described two pieces of tube plate structures, as shown in Figure 4, described angle direction is relative with the direction of the circular arc line structural bending of speculum, between the angle a that the focus D of speculum 20 is formed at tube plate structure.
Traditional heat collector is all be set directly in focus by thermal-collecting tube, once position offsets, then heat would not thermal-arrest in thermal-collecting tube, pass through said structure, sunlight is at speculum 20, tube plate structure is reflexed to, by heat thermal-arrest in the thermal-collecting tube 21 in tube plate structure by speculum 20.By this structure, even if because to install or operation problem causes tube plate structure position to change, then solar energy still can thermal-arrest in thermal-collecting tube 21, thus avoid thermal loss; Simultaneously because traditional heat collector is all be set directly in focus by thermal-collecting tube, cause thermal-collecting tube hot-spot, cause thermal-collecting tube local losses excessive, life-span is too short, even cause thermal-collecting tube over-heat inside, produce superheated steam, be full of whole thermal-collecting tube, cause thermal-collecting tube internal pressure excessive, damage thermal-collecting tube, and take the structure of the application, both heat can be absorbed fully, and can, by dispersion relative for heat, avoid heat too concentrated again, make overall thermal-collecting tube absorb heat evenly, extend the service life of thermal-collecting tube.
As one preferably, the focus D of speculum 20 is positioned on the mid point of two pieces of tube plate structure least significant end lines.By above-mentioned setting, can ensure to absorb solar energy to the full extent, avoid solar energy to lose because of focal shift, can also ensure that platy structure may reduce the sunlight of irradiation on speculum 20 blocked simultaneously as far as possible.Prove by experiment, adopt said structure, the effect of solar absorption is best.
Find in practice, the caliber of thermal-collecting tube 21 can not be excessive, if caliber is excessive, water then in thermal-collecting tube 21 can not heat fully, cause heating effect very poor, otherwise caliber is too small, water then in thermal-collecting tube can be overheated, in like manner, distance between thermal-collecting tube 21 is also met the demands, if the distance between thermal-collecting tube 21 is excessive, the volume of the water then in thermal-collecting tube 21 is too small, water can be caused overheated, equally, if the distance between thermal-collecting tube 2 is too small, then thermal-collecting tube distribution is too close, cause the problem that the water in thermal-collecting tube 21 cannot reach predetermined, or more extra auxiliary heating instrument must be needed, for the length of tube plate structure, also meet certain requirements, if tube plate structure is oversize, then can shelter from the too much sunlight being irradiated to speculum 20, the heat causing heat collector to absorb sunlight reduces, cause and reach desirable heating state, if the length of tube plate structure is too small, then causes too much solar energy heating on the thermal-collecting tube of small size, cause thermal-collecting tube to be heated concentrated, but also the solar energy of a part of thermal-arrest can be caused directly not have thermal-arrest in thermal-collecting tube, but directly reflex to outside, for angle a, same principle, if angle is excessive, then portion launches excessive to area on the mirror, then can shelter from the too much sunlight being irradiated to speculum 20, if angle area is too small, then the solar energy that there will be a part of thermal-arrest does not directly have thermal-arrest in thermal-collecting tube, but directly reflex to outside, cause the loss of heat.Therefore following relation is met for the angle between the distance between the length of tube plate structure, thermal-collecting tube internal diameter, thermal-collecting tube, tube plate structure, circular arc line radius:
The circular arc line radius of speculum is R, and the length of every block tube plate structure is R1, and the radius of thermal-collecting tube is R2, and on same tube plate structure, the distance in the center of circle of Neighbor Set heat pipe is L, and the angle between two pieces of tube sheets is a, then meet following formula:
