Abstract
A flat type solar energy hollow heat collection band is provided. A panel and a back plate of a cover plate (3) are provided with two steel glass plates; the cavity between the panel and the back plate is hollow and is filled with inert gas; spaced stickers (4) are disposed around fins (2) at the periphery between the panel and the back plate; a concave groove (5) is formed between the spacing stickers, and the panel and the back plate; and a heat insulation layer (6) is filled on the concave groove around the periphery of the heat collection band. Shortcomings of vacuum plat type heat collection band are overcome, and simple production technique, a low production cost and good sealing property are provided.
Description
Technical field:
The invention belongs to the solar heat collection strip technical field of structures.
Background technology:
Existing solar heat collection strip, be the vacuum plate heat collection band, this heat-collecting strip adopts usually vacuum heat-pipe is arranged in the dual-layer vacuum glass plate holder layer, rely on vacuum heat-pipe to place the outer condensation end heat release of glass plate to heat cold water, then by the water in the thermal cycle heating solar water tank between upper circular tube and the following circulation pipe, the vacuum plate heat collection band of this solar energy is owing to exist the vacuum production technology, relatively more difficult on manufacture craft, the production cost height, difficult sealing is with long-term assurance; In sealing, around heat-collecting strip, adopt sealing strip to center on sealing, technology is complicated.
The weak point that this structure exists is, panel and backboard all adopt armorplate glass, and the centre is a vacuum, makes the increase of vacuum technology and hermetically-sealed construction difficulty, and cost is too high.
Summary of the invention:
Purpose of the present invention provides in order to overcome above-mentioned defective that existing solar energy equipment heat-collecting strip exists and weak point just that a kind of production technology is simple, production cost is low, the plate type solar hollow heat-collecting strip of good seal performance.
The objective of the invention is to realize by following technical solution.
The present invention is made up of thermal-collecting tube, fin and cover plate, it is characterized in that, the panel of cover plate and backboard are two armorplate glasses; Cavity between panel and backboard is set to hollow, is filled with inert gas in hollow cavity, to strengthen its heat-insulating property; The fin that all around centers between panel and backboard is provided with parting bead; Form a groove between parting bead and panel and the backboard; On the groove of heat-collecting strip periphery, be filled with the polyurethane thermal insulation layer; Thermal-collecting tube two ends of the present invention both can be stretched out the two ends that are positioned at cover plate respectively, also can be located on an end of cover plate.When the thermal-collecting tube two ends was located on an end of cover plate, the thermal-collecting tube body structure that is positioned at hollow cavity was U-shaped or the crooked shape that is no less than a U-shaped.
The invention has the beneficial effects as follows, owing on the thermal-collecting tube of heat-collecting strip, adopt the production technology of hollow, simplified process procedure greatly, effectively reduce the cost of manufacture of product, and be filled with polyurethane as thermal insulation layer in the groove that between parting bead and panel and backboard, forms, effectively played insulation effect.
Further set forth content of the present invention below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1;
The structural representation that Fig. 3 stretches out in the same way for the thermal-collecting tube two ends;
Fig. 4 is many kinkings of thermal-collecting tube structure schematic diagram.
The specific embodiment:
As Fig. 1, Fig. 2, the present invention is made up of thermal-collecting tube 1, fin 2 and cover plate 3, it is characterized in that, and the panel of cover plate 3 and backboard are two armorplate glasses; Cavity between panel and backboard is set to hollow, is filled with inert gas in hollow cavity, to strengthen its heat-insulating property; The fin 2 that all around centers between panel and backboard is provided with parting bead 4; Form a groove 5 between parting bead 4 and panel and the backboard; Be filled with thermal insulation layer 6 on the groove 5 of heat-collecting strip periphery, insulating layer material is a polyurethane; On the two ends of thermal-collecting tube 1, offer connecting thread 7.Press Fig. 1 structure of thermal-collecting tube, the present invention and solar energy connected mode can be connected with upper circular tube the thermal-collecting tube two ends respectively with following circulation pipe, form the Natural Circulation of solar water heater; Until water is heated; Also can make interior hot water of thermal-collecting tube and the water in the water tank force thermal cycle with whole solar energy equipment by being connected controller and the circulating pump on upper circular tube and the following circulation pipe.
The present invention also can be with single heat-collecting strip as module, be combined into the larger area solar thermal collector with series system or parallel way, carry out thermal cycle with Natural Circulation or forced circulation (adding cartridge controller and circulating pump) mode, and then the water in the heating solar water tank.
The present invention also can adopt thermal-collecting tube is arranged to a U-shaped pipe, or many U-shapeds pipe, as Fig. 3, and Fig. 4, the thermal-collecting tube two ends is stretched out simultaneously at cover plate 3 one ends; No matter the thermal-collecting tube of heat-collecting strip of the present invention is reach up and down, or the U-shaped tubular type, both can be connected in parallel each other between the flat heat collecting band, also can be connected in series each other.Its working method is: after sunlight sees through cover plate 3, heat-absorbing paint on the fin 2 begins heat absorption, heat conducts to thermal-collecting tube 1, insulation layer 6 plays insulation effect, because thermal-collecting tube 1 directly is communicated with the upper circular tube and the following circulation pipe of solar energy, under the effect of controller and circulating pump, system forms thermal cycle, and then the water in the heating solar water tank.
