Description
Technical field
What the present invention relates to is the through solar energy heat collection pipe of a kind of S shape, especially relates to a kind of metal and beading or bonding solar vacuum heat-collecting pipe, belongs to technical field of solar utilization technique.
Technical background
What existing solar energy heat collection pipe generally used is the blind pipe of an end opening one end sealing, blind pipe is because can not contact, the solar thermal collection system of being made up of them is to utilize many thermal-collecting tubes and the different temperature difference of water generates in the water storage box, different specific weight and Natural Circulation, so exist: 1, the circular heating speed of water is very slow; The thermal efficiency is low; 2, the surplus water in the thermal-collecting tube can't be discharged and take, and utilization rate is low; 3, pile up foreign material and generation incrustation scale in the thermal-collecting tube easily, and can't clean, hot water can not eat; 4, purely can not bear higher hydraulic pressure for glassware.
In order to address these problems, another kind of solar energy heat collection pipe is the through type metal inner pipe, and two ends adopt metal and glass by welding or bonding.But because the expansion factor of splashing of glass and metal differs greatly, technology difficulty is very high, does not reach the purpose that keeps vacuum for a long time, so do not have or very difficult formation industrialization.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of by changing the structure of thermal-collecting tube, glass and metal have been solved because the different flexible problem of expansion coefficient difference separately, thereby realized that technology is simple, easy to manufacture, reliability is high, and improved heat utilization efficiency greatly, hot water can all be discharged, and can bear higher hydraulic pressure, applicable to the through solar energy heat collection pipe of S shape of medium and high temperature needs.
The objective of the invention is to finish by following technical solution, it mainly includes interior metal tube, outer glass pipe, and described interior metal tube is the metal tube of S shape bending; The two ends of outer glass pipe have at least glass end cap to seal and form vacuum between inner and outer pipes.
Compacting or fusion have alloy material in the middle of the described glass end cap, and described interior metal tube stretches out from this alloy material, and alloy material and interior metal tube welded seal; Described glass end cap is by welding or bondingly fixedly connected with outer glass pipe; Described alloy material is that seal welding is established when being S shape metal inner pipe and glass tube composition one.
The outermost at described outer glass pipe two ends is provided with metal cap, is filled with insulation material in this metal cap, and is fixedly connected by colloid or jointing material between outer glass pipe and metal cap.
Described outer glass pipe is glass round tube or glass square tube or glass rectangle pipe or glass flat garden pipe or glass oval pipe.
The reverberation material has been set up in the inboard of described outer glass pipe or the outside.
On the described metal cap leg is installed.
For the surface area of metal tube in increasing, the outside of described interior metal tube is welded or is wrapped up or amplexiformed sheet metal, and the composite that comprises more than one metallic elements is arranged and the heat absorption rete that forms in its surface attachment.
Be welded with at least one ring of cooling down on metal tube or the sheet metal in described.
Two exposed junctions of metal tube are that connector is made into straight pipe type or screw-type or fusing type or plug-in respectively or has the flange form of installing hole for the connector that provides is provided many thermal-collecting tubes in the described S shape.
The through solar energy heat collection pipe of S shape of the present invention is installed in the outside of building, and they are can many to be connected in series the back and the solar thermal collection system that produces water temperature more than 100 ℃ or steam.
After solar energy heat collection pipe is raise by the solar radiation temperature, heat is absorbed by the absorption film on the metal inner pipe, water in the interior metal tube is by continuous progressively intensification, because the temperature of the through solar energy heat collection pipe of S shape can reach more than 200 ℃, so flowing in pipe, water after progressively heating up, can produce greater than water temperature more than 100 ℃ or steam, because temperature is too high or steam can produce certain pressure, so pipe is metal material in being provided with.Because the expansion of glass and metal differs during variations in temperature, so the length direction of interior metal tube is designed to continuous S-shaped, can adapt to the alloy material that expands between the two, thereby eliminate the flexible and rate of rising of splashing between them in the joint employing.
The present invention compares with the technology of existing thermal-collecting tube, has the following advantages: 1, the heat energy utilization rate improves greatly; 2, metal and glass have been solved because of the different problems that can't weld and keep vacuum of the coefficient of expansion; 3, can not pile up foreign material, be difficult for scaling, safety and sanitation, hot water is edible; 4, interior pipe can bear the above pressure of 5Mpa; 5, can produce the water or the steam of high heat, be used for substituting large-sized solar heat collecting engineerings such as boiler, industrially drying, air conditioner refrigerating or generating; Has far reaching significance to efficiently utilizing solar energy and preserving the ecological environment.
