As shown in Fig. 2 the angle direction is relative with the direction of the circular arc line structural bending of speculum, the focus D of speculum 9 is positioned at pipe
Between the hardened angle a being configured to.
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 9, and tube plate structure is reflexed to by speculum 9,
By in the thermal-collecting tube 10 in heat thermal-arrest to tube plate structure.By this structure, even if because installation or operation problem cause
Tube plate structure position changes, then solar energy still can thermal-arrest into thermal-collecting tube 10, so as to avoid thermal loss；Simultaneously as
Traditional heat collector is all that thermal-collecting tube is set directly in focus, causes thermal-collecting tube hot-spot, causes thermal-collecting tube locally to damage
Lose 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 thermal-collecting tube
Internal pressure is excessive, damages thermal-collecting tube, and takes the structure of the application, both can sufficiently absorb heat, again can be by heat
Measure relative scattered, avoid heat from excessively concentrating so that overall thermal-collecting tube heat absorption is uniform, extends the service life of thermal-collecting tube.

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 9 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 10 can not be excessive, if caliber is excessive, the water in thermal-collecting tube 10 can not
Sufficiently heated, cause heating effect very poor, on the contrary caliber is too small, then and the water in thermal-collecting tube can overheat, similarly, for collection
The distance between heat pipe 10 also meets to require, if the distance between thermal-collecting tube 10 is excessive, the volume of the water in thermal-collecting tube 10
It is too small, water can be caused to overheat, equally, if the distance between thermal-collecting tube 10 is too small, thermal-collecting tube distribution is too close, causes thermal-collecting tube
Water in 10 is unable to reach the problem of predetermined, or is necessarily required to more extra auxiliary heating tools；For tube plate structure
Length, also meet certain requirements, if tube plate structure is oversize, the excessive sunlight for being irradiated to speculum 9 can be sheltered from, made
The heat that sunlight is absorbed into heat collector is reduced, and is caused to reach preferable heating state, if the length of tube plate structure is too small, is made
Into excessive solar energy heating to the thermal-collecting tube of small area, cause thermal-collecting tube is heated to concentrate, but also a part of collection can be caused
The solar energy of heat does not have thermal-arrest directly into thermal-collecting tube, but directly reflexes to outside；For angle a, same principle, if
Angle is excessive, then portion's expansion is excessive to area on the mirror, then can shelter from the excessive sunlight for being irradiated to speculum 9, such as
Fruit 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 reflects
To outside, the loss of heat is caused.Therefore for the distance between the length of tube plate structure, thermal-arrest bore, thermal-collecting tube, tube sheet
Angle, circular arc line radius between structure 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.
Preferably, c=0.4002, b=0.0275.
Preferably, with angle a increase, c, b coefficient become larger.So more meet the need of real work
Will.
Preferably, the projection of augmentation of heat transfer is provided on the lower wall surface (face relative with speculum 9) of tube plate structure,
To strengthen the absorption to solar energy.Along the middle part (i.e. extreme higher position) of tube plate structure to both sides extreme lower position (i.e. Fig. 1 thermal-collecting tubes
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
The material of pipe is easily damaged at high temperature, and the temperature of whole thermal-collecting tube can be kept uniform, increased the service life.
Preferably, along the link position (i.e. the middle part of tube plate structure) of two pieces of tube plate structures to both sides (i.e. Fig. 1 thermal-arrests
Pipe A is to B, C direction) extension, the density of protrusions more and more higher of the lower wall surface of thermal-collecting tube.Main cause is that middle part is heated minimum, and
Extend from middle part to both sides, absorb heat and gradually rise.By the continuous rise of density of protrusions, whole thermal-collecting tube can be caused
Reclaimed water is heated evenly, and avoids that medium temperature is too low and both sides temperature is too high.The material of the thermal-collecting tube of centre can also so be avoided
Material is easily damaged at high temperature for a long time, and the temperature of whole thermal-collecting tube can be kept uniform, increased the service life.
Preferably, the inwall of thermal-collecting tube 10 can set fin, such as straight fins or helical fin can be set, no
It is different with the interior fin height of thermal-collecting tube, along the link position (i.e. the middle part of tube plate structure) of two pieces of tube plate structures to both sides
(i.e. Fig. 1 thermal-collecting tubes A to B, C direction) extension, the height of fin gradually decrease.Main cause is with above setting the reason for raised
It is identical.
