Detailed description of the invention
As it is shown in figure 1, this one fin-tube type flat plate collector, including absorber plate 1, runner, cover glass tube 2, framework 3.What constitute runner has water inlet pipe 4, outlet pipe 5, connecting tube 6, arm 7.
One end of described arm 7 connects with connecting tube 6, and the other end connects with water inlet pipe 4/ outlet pipe 5.
Welding absorber plate 1 on arm 7, absorber plate 1 and arm 7 welding are to reduce thermal resistance for main purpose, it is possible to adopt the modes such as electric resistance welding, plasma weldering, argon arc welding, Laser Welding.The length direction of absorber plate 1 is parallel with the axis of arm 7.The front and back of absorber plate 1 is equipped with coating for selective absorption, it is possible to adopt the methods such as chemical method, magnetron sputtering method, anodic oxidation, spraying to prepare.Absorber plate 1 is positioned at the sensitive side of arm 7.The width of absorber plate 1 is more than the diameter of arm.
Preferred: namely as in figure 2 it is shown, the cross section of absorber plate 1 is " V " type, and be that the left and right sides of cross section is lower than middle part.
In addition the cross section of absorber plate 1 can be also arc, when being elected as arc, is also the left and right sides the adopting cross section set-up mode lower than middle part.
All right: the cross section of absorber plate 1 is " one " type structure.
Further: the width (i.e. air line distance between edge, the absorber plate left and right sides) of described absorber plate 1 is the 160%～185% of cover glass tube 2 diameter；Arm 7 is positioned at below the axis of cover glass tube 2 in cover glass tube 2.
Arm 7 and absorber plate 1 are placed in the cover glass tube 2 that two ends seal.The two ends of cover glass tube are sealed by stopper 22.Arm 7 is connected with connecting tube 6/ water inlet pipe 4/ outlet pipe 5 after stopper 22.Connection between arm 7 with connecting tube 6 can: mode one be adopt arm carry out groove after weld, as shown in Figure 3；Mode two is to adopt thread connecting mode, as shown in Figure 4.Connected mode between arm 7 and water inlet pipe 4, outlet pipe 5 is also such, it is possible to be welding, threaded or other connected modes, signal of just no longer individually drawing.
Being provided with reflection part in cover glass tube 2, reflection part is positioned at below described arm 7；The width of reflection part is more than the width of absorber plate 1.
Preferred reflection part is highly reflecting films 21, as in figure 2 it is shown, highly reflecting films 21 can adopt sol method, magnetron sputtering method to prepare.In addition reflection part can also be insert the reflecting mirror in cover glass tube 2.
The end of cover glass tube 2 is arranged in framework 3, fills the insulation material 8 of high temperature resistant in framework 3.Connecting tube 6, water inlet pipe 4, outlet pipe 5 are respectively positioned in framework 3, and insulation material 8 wraps up.Insulation material adopts the material of the high temperature resistant such as polyurethane, rock wool.
