In addition, in chamber 11, solar panel 1 is provided with getter pump to help to keep vacuum.
Thereby cooling tube is welded to framework two ends.The longitudinal separation part contacts with transparent wall with opposing environmental pressure and support transparent wall, and cross partitions contact with transparent wall, so the permission absorber whole length of clad battery plate interruptedly not.
Fig. 2 illustrates a kind of possible connection between longitudinal separation part and the cross partitions; Particularly, Fig. 2 illustrates longitudinal separation part and cross partitions the infall at them is connected through the connecting portion that can slide along the longitudinal separation part.
This connection is not very tight, and allows longitudinal separation part 3 edges vertically to move (and cross partitions 4 is fixed simultaneously) slightly to adapt to the pressure of transparent wall; This connection also allows longitudinal separation part 3 motion slightly longitudinally, to adapt to its thermal expansion.
The operation of solar panel of the present invention becomes clear from a content of describing and illustrating, and said operation is following basically.
So, the end of distance piece 4 is welded to framework 2, and the end of distance piece 3 can freely-movable.
Then, absorber 4 is assembled in the framework 2; For this reason, will absorb panel 14a, 14b (its longitudinal length equals the longitudinal length of chamber 11 basically) and connected cooling tube 15 and be placed on the cross partitions 4, cooling tube 15 will be inserted in the seat portion 22.
