It is cut on the basis of the point B and point A in the symmetric reflective face 95 in face, and is constituted angle by starting point and central axis of point A and point B
For the V-arrangement state reflecting surface of ψ, the minimum point of V-arrangement state reflecting surface is C point.To the reflecting surface incidence of V-arrangement state sunlight according to angle ψ
To determine the reflection towards round absorption tube.Due to from optical angle, the second of the second reflecting surface 92 of V-arrangement state, V-arrangement state
The distance g for linking to round 90 minimum point of absorption tube of two upper extreme point AB in the symmetric reflective face 93 of reflecting surface should be no more than circle
The radius r1 of shape absorption tube 90, therefore, the second of the second reflecting surface 92 of the diameter r2 of circular glass pipe 91 and V-arrangement state, V-arrangement state
The symmetric reflective face 93 of reflecting surface is formed by angle ψ and is restricted.If crossing tangent line and the central axis institute of the round absorption tube 90 of point C
The angle of formation is α, then ψ is defined by following formula.
ψ >=90 °-α, sin2α+sinα≥1
By ψ determining in the manner come the second reflecting surface 92 of the V-arrangement state formed, V-arrangement state second
In the symmetric reflective face 93 of reflecting surface, it is to radius to the sunlight of plane of the opening incidence where AB with the angle of (90 ° of-ψ)
The round absorption tube 90 of r1 reflects.The height h=r of V-arrangement state reflecting surface1cot2ψ+g(cot2ψ -1)/2, the width of V-arrangement state reflecting surface
Spend w=h*tan ψ.The width of V-arrangement state reflecting surface is the half of straight line AB distance.
