The collector structure is as shown in fig. 6, including thermal-collecting tube 2, speculum 1 and collecting plate 3, adjacent two thermal-collecting tubes
Connected between 2 by collecting plate 3, so that forming tube plate structure between multiple thermal-collecting tubes 2 and adjacent collecting plate 3;It is described too
It is positive can collector system include two pieces of tube plate structures, shape a at a certain angle between two pieces of tube plate structures, as shown in fig. 7,
The angle direction is relative with the direction of the circular arc line structural bending of speculum, and the focus D of speculum 1 is formed positioned at tube plate structure
Angle a between.
Traditional heat collector is all that thermal-collecting tube is set directly in focus, once position shifts, then heat is not just
For meeting thermal-arrest into thermal-collecting tube, by said structure, sunshine is radiated at speculum 1, and tube plate structure is reflexed to by speculum 1,
By in the thermal-collecting tube 2 in heat thermal-arrest to tube plate structure.By this structure, even if because installation or operation problem cause pipe
Harden structure position changes, then solar energy still can thermal-arrest into thermal-collecting tube 2, so as to avoid thermal loss;Simultaneously as pass
The heat collector of system is all that thermal-collecting tube is set directly in focus, causes thermal-collecting tube hot-spot, causes thermal-collecting tube local losses
Excessive, the life-span is too short, or even causes thermal-collecting tube over-heat inside, produces superheated steam, full of whole thermal-collecting tube, causes in thermal-collecting tube
Portion's pressure is excessive, damages thermal-collecting tube, and takes the structure of the application, both can sufficiently absorb heat, again can be by heat
Relative is scattered, avoids heat from excessively concentrating so that overall thermal-collecting tube heat absorption is uniform, extends the service life of thermal-collecting tube.
As one preferably, the focus D of speculum 1 is on the midpoint of two pieces of tube plate structure least significant end lines.By upper
State setting, it is ensured that absorb solar energy to the full extent, avoid solar energy from being lost because of focal shift, also ensure simultaneously
Platy structure is likely to reduced sunlight of the irradiation blocked on speculum 1 as far as possible.It is experimentally confirmed, using said structure, too
The absorbent effect of sun is best.
In practice, it has been found that the caliber of thermal-collecting tube 2 can not be excessive, if caliber is excessive, the water in thermal-collecting tube 2 can not enter
Row sufficiently heating, causes heating effect very poor, otherwise caliber is too small, then the water in thermal-collecting tube can overheat, similarly, for thermal-arrest
The distance between pipe 2 also meets requirement, if the distance between thermal-collecting tube 2 is excessive, the volume of the water in thermal-collecting tube 2 is too small,
Water can be caused to overheat, equally, if the distance between thermal-collecting tube 2 is too small, thermal-collecting tube distribution is too close, causes in thermal-collecting tube 2
Water is unable to reach the problem of predetermined, or is necessarily required to more extra auxiliary heating tools;For the length of tube plate structure,
Also meet certain requirements, if tube plate structure is oversize, the excessive sunlight for being irradiated to speculum 1 can be sheltered from, cause thermal-arrest
The heat that device absorbs sunlight is reduced, and causes to reach preferable heating state, if the length of tube plate structure is too small, is caused excessive
Solar energy heating thermal-collecting tube is heated to be concentrated on the thermal-collecting tube of small area, causing, but also a part of thermal-arrest can be caused too
Sun can be directly without thermal-arrest into thermal-collecting tube, but directly reflexes to outside;For angle a, same principle, if angle mistake
Greatly, then portion's expansion is excessive to area on the mirror, then the excessive sunlight for being irradiated to speculum 1 can be sheltered from, if angle
Area is too small, then the solar energy of a part of thermal-arrest occurs and does not have thermal-arrest directly into thermal-collecting tube, but directly reflexes to outside,
Cause the loss of heat.Therefore for the distance between the length of tube plate structure, thermal-arrest bore, thermal-collecting tube, tube plate structure it
Between angle, circular arc line radius meet following relation:
The circular arc line radius of speculum is R, and the length of every piece of tube plate structure is R1, and the radius of thermal-collecting tube is R2, same pipe
The distance in the center of circle of adjacent thermal-collecting tube is L in harden structure, and the angle between two pieces of tube sheets is a, then meets equation below:
R1/R=c*sin (a/2)b,
0.18<R2/L<0.34,
Wherein c, b are coefficient, 0.39<c<0.41,0.020<b<0.035;
0.38<R1/R<0.41,80 °<=A<=150 °, 450mm<R1<750mm,1100mm<R<1800mm,90mm<L<
150mm,20mm<=R2<50mm.

A is to B, C direction) on bearing of trend, the height of projection more and more higher of the lower wall surface of thermal-collecting tube.Find in an experiment, from middle part to
Both sides extend, and caloric receptivity gradually rises, and are because there is the stop of tube plate structure by analyzing main cause, cause middle part heated most
It is few, and extend from middle part to both sides, absorb heat and gradually rise.By the continuous rise of height of projection, can cause whole
Thermal-collecting tube reclaimed water is heated evenly, and avoids that both sides temperature is too high and medium temperature is too low.The thermal-arrest of centre can also so be avoided
