Summary of the invention
The object of the present invention is to provide a kind of thermal efficiency height, the multidimensional solar vacuum heat-collecting tube that production cost is low.
Technical solution of the present invention is: multidimensional solar vacuum heat-collecting tube, and it comprises outer tube and interior pipe, interior pipe is unsettled to be arranged in the outer tube, is vacuum chamber between outer tube and the interior pipe, it is characterized in that: outer tube is one, interior Guan Yousan root; Interior tube opening end is provided with the boundling cover, and boundling puts to be provided with and is three uniform through holes of " product " font, and the openend of three interior pipes inserts respectively in the corresponding hole, sealed attachment between interior pipe and the boundling cover; Head cluster is the tubular that an end is big, an end is little, and the big end sealed attachment of head cluster puts at boundling, and the small end of head cluster is directly or by sleeve pipe and outer tube opening part sealed attachment.
Pipe and outer tube are blind pipe in described, and socket in the same way.
Be provided with a ring support in the described outer tube, ring support is provided with and is three uniform through holes of " product " font, and interior pipe cecum interts respectively on support in the corresponding hole.
Being provided with the cross section between described outer tube and the interior pipe is the optically focused reflecting surface of arc, and the optically focused reflecting surface is arranged on a side of pipe in all.
Tube-surface is provided with solar energy decalescence films in described.
Described sealed attachment is meant welding or splicing or at the union end interface sealing device is set.
The present invention is owing to be provided with in some pipe in an outer tube, so heat collector surface is bigger, and it is longer to adopt heat aging, and firing rate is faster, has saved the production cost of outer tube simultaneously, so the present invention has thermal efficiency height, advantage that production cost is low.
