Abstract

A solar energy heat collector header made of a ''collecting cavity'' core with a circular cross section is provided, wherein a branch pipe projecting outwards form the ''collecting cavity'' has smaller diameter, which is good for decrease the spacing between vacuum tubes so as to increase heat collecting power per unit lighting area and to improve the pressure-bearing capability of the ''collecting cavity'' core and the seal ring part. When assembling the heat collector, the nozzle of the complete glass vacuum tube is housed out of the branch pipe of the ''collecting cavity'', so that the sealing part of the complete glass vacuum tube is arranged within the tube. For a heat collector shaped like a Chinese character ''fei'', since the complete glass vacuum tube is housed on the two symmetrical branch pipes of the collecting tube, two glass tubes which are face to face with each other will not contact during assembling the heat collector. In addition, the ''collecting cavity'' core is combined with tee joint and cross tee or is once-formed by using processes such as huffing, extruding and thermosetting.

Description

A kind of solar thermal collector header

Affiliated technical field

The utility model relates to a kind of whole glass vacuum tube solar energy heat collector.

Background technology

" collection chamber " fuse of whole glass vacuum tube solar energy heat collector normally adopts stainless steel or other materials to do, this class " collection chamber " is a cuboid, the long rectangular face of cuboid has in order to insert the hole of the all-glass vacuum tube mouth of pipe, and sealing ring is arranged in the hole.Mouth of pipe insertion with all-glass vacuum tube when being assembled into heat collector has in the hole of sealing ring.The solar heat collector of all-glass vacuum tube (East and West direction) traverse can also be made " non-" font, promptly the right and left in " collection chamber " all has in order to insert the hole of the all-glass vacuum tube mouth of pipe, sealing ring is arranged in the hole, when being assembled into heat collector the mouth of pipe of all-glass vacuum tube inserted in the aspectant hole that has a sealing ring.Have in the hole of sealing ring because the all-glass vacuum tube mouth of pipe all inserts, because the reason of sealing ring distance is big thereby be difficult to reduce space between the vacuum tube, " collection chamber " is difficult to increase the quantity of all-glass vacuum tube in unit length in other words between the hole.In addition, when the liquid operating pressure increased to some extent in " collection chamber ", the phenomenon of leakage can take place when serious in " collection chamber " fuse easy deformation that cross section is square.Furthermore, because the sealing position is at the outer tube of all-glass vacuum tube, the diameter of its sealing ring is bigger, thus the bearing capacity at sealing ring position also a little less than, easy-to-leak liquid.Also have, " non-" font solar heat collector for all-glass vacuum tube (East and West direction) traverse, because aspectant glass tube all is inserted in " collection chamber " the inside, tend to take place that two glass tubes clash and the phenomenon of fragmentation in the process of assembling heat collector " collection chamber " fuse in.

Summary of the invention

The utility model provides a kind of whole glass vacuum tube solar energy heat collector header, the tube pitch that purpose is to dwindle vacuum tube to be increasing the collector power of unit daylighting area, and improves the bearing capacity in " collection chamber " and stop the glass tube head-on collision and broken when assembling of " non-" font heat collector.

The technical scheme that its technical problem that solves the utility model adopts is: " collection chamber " fuse is changed into sealing position circular and heat collector design in the interior pipe of all-glass vacuum tube by what cross section was square.Arm on rounded " collection chamber " fuse of cross section, its external diameter be less than the internal diameter of all-glass vacuum tube, during assembling on the interior pipe back boxing of all-glass vacuum tube sealing ring, be enclosed within then on the arm of " collection chamber " fuse.

The beneficial effects of the utility model are that the bearing capacity of " collection chamber " fuse that cross section is rounded is more many than square raising; The sealing position that becomes the all-glass vacuum tube outer tube is interior pipe, and the diameter of its sealing ring is less, thereby has also improved relatively at the bearing capacity at sealing ring position; Arm diameter on the collector has diminished, and helps dwindling the tube pitch of vacuum tube to increase the collector power of unit daylighting area; For " non-" font heat collector, because aspectant all-glass vacuum tube is to be enclosed within on the arm of collector, two glass tubes thereby can not be collided and fragmentation never again " collection chamber " fuse in " meet " during assembling.

The specific embodiment

As Fig. 1, the rounded collector (1) of cross section is a metal pipe material, on its pipe shaft according to the perforate on corresponding size position of the quantity of set vacuum tube, and adopt technology such as soldering load onto diameter less than a bit of metal pipe material of pipe in the all-glass vacuum tube as cambered outwards arm (2), become rounded " collection chamber " fuse of cross section with this.For freeze proof or the like reason can also be inserted one or several metal tube as the metal tube (6) that is placed in the collector in the rounded collector of cross section (1), make between the rounded collector (1) of itself and cross section and form a pair of heat exchange relationship, thereby become " collection chamber " fuse of a kind of double loop solar thermal collector header.Also be provided with rubber seal (8) between cambered outwards arm (2) and the all-glass vacuum tube (5), have on the side of header shell (3) with the hole of cambered outwards arm (2) respective numbers in order to inserting all-glass vacuum tube (5), and between itself and " collection chamber " fuse fill insulant material 4.

As Fig. 2, the cambered outwards arm (2) that symmetrical technologies such as both sides employing soldering are loaded onto on the collector (1) that cross section is rounded and this collector pipe shaft constitutes " collection chamber " fuse of heat collector header.Also can (as Fig. 1) when needing in the rounded collector of cross section (1), insert one or several metal tube as the metal tube (6) that is placed in the collector.Have on two symmetrical sides of header shell (3) in order to insert the hole of all-glass vacuum tube (5).Arrangement such as Fig. 1 of rubber seal (8) and insulation material (4).

As Fig. 3, " collection chamber " fuse can adopt the three links metal tube of " spigot-and-socket " joint to do, specific practice is: the three links pipe fitting (9) of " spigot-and-socket " joint according to needed quantity headtotail, is located to impose soldering or " card is pressed " pincers in " bell and spigot joint (7) ".

As Fig. 4, " collection chamber " fuse of " non-" font heat collector can adopt " four-way " metal tube of " spigot-and-socket " joint to do, specific practice is: " spigot-and-socket " joint " four-way " pipe fitting (10) according to needed quantity headtotail, is located to impose soldering or " card is pressed " pincers in " bell and spigot joint (7) ".

If common three links or " four-way " metal tube, as long as add " bundle connects " of corresponding size at the position that connects and impose soldering or " card is pressed " pincers.All three links or " four-way " also can adopt the nonmetallic materials of anti-middle high temperature to make except metal, and can adopt technologies such as inflation, mold pressing, thermosetting to make being spliced of duplex or multiple in advance." collection chamber " of the present utility model fuse can also adopt technologies such as inflation, mold pressing, thermosetting to make metal material or nonmetallic materials disposal molding.
