Abstract
A kind of metal-glass head seal thermal-collecting tube, belong to technical field of solar utilization technique, comprise outer glass tube, collector metal pipe, can becket be cut down, to cool down the compositions such as ring, the beneficial effects of the utility model are that structure is simple, use reasonable in design, and effectively avoiding expands with heat and contract with cold causes the explosion of outer glass tube that equipment can not normally be used, formed again the heat absorption capacity coating for selective absorption of sunray being added to collector metal pipe by magnetic control sputtering vacuum coating process, increase the service life.
Description
Technical field
The utility model relates to technical field of solar utilization technique, is specifically related to a kind of metal-glass head seal thermal-collecting tube.
Background technology
Solar thermal collector is the extremely crucial parts of solar energy hot-cast socket, its structure and operational mode determine solar energy conversion efficiency, install use environment, the security of system cloud gray model, lifetime of system and system total cost.What current consumption was maximum is exactly all-glass vacuum thermal-collecting tube, and because the manufacturing process of glass heat-collecting vacuum tube is simple, energy consumption is low, and discharge is few, and unprecedented industrialization, also make the manufacturing cost of glass-vacuum tube extremely low, and glass heat-collecting vacuum tube is anticorrosion, less scaling.Therefore be convenient to penetration and promotion.But fatal defects is not pressure-bearing, easily booster, not antifreeze, is difficult to be applied on heat collecting engineering.
Glassy metal thermal-collecting tube is made up of two parts, heat collection body and heat-insulation layer.If directly adopt metal and glass evacuated sealing-in, its technique is quite complicated, and yield rate is extremely low, and cost is high, then uneven in temperature due in system cloud gray model, more easily bursts, air leakage failure.So apply very few on the product for civilian use, be used for slot type thermal-arrest electricity generation system.
Summary of the invention
The utility model object is to provide a kind of not contact working medium, pressure-bearing, the metal-glass head seal thermal-collecting tube that anticorrosion, the thermal efficiency is high, thermal emissivity is low.
The utility model is achieved in the following ways a kind of metal-glass head seal thermal-collecting tube, comprise outer glass tube, collector metal pipe, cool down ring and can cut down becket composition, described collector metal pipe is arranged in outer glass tube, the two ends of collector metal pipe respectively roll welding are connected to and can cut down becket, the two ends of outer glass tube are connected with one end sealing by fusing that can cut down becket respectively by 10 flint glass Fs, it is then vacuum layer between collector metal pipe and outer glass tube, ring of cooling down is fixed on the two ends of the collector metal pipe in vacuum layer, the gas that collector metal pipe and glass tube discharge can be absorbed, vacuum state in available protecting vacuum layer.
Described outer glass tube material used is high-boron-silicon glass, one end sealing by fusing that outer glass tube can cut down becket by 10 flint glass Fs reaches sealing function in glass, moreover, again because the coefficient of expansion of 10 flint glass Fs is with the expansion coefficient similar that can cut down becket, can not produce because cold and hot expansion causes outer glass tube to break; Described collector metal pipe is sus444 ferrite stainless steel pipe, forms coating for selective absorption to sunray at the outer surface of collector metal pipe by magnetic control sputtering vacuum coating process.
Described cut down becket side sectional shape is S type, and being arranged to S type has good retractility, greatly alleviates the tension force and pulling force that bring owing to expanding with heat and contract with cold.
The beneficial effects of the utility model are that structure is simple, reasonable in design, by selecting the material of high borosilicate and No. 10 transitional glasses, effectively avoid the explosion causing outer glass tube owing to expanding with heat and contract with cold, equipment can not normally be used, formed again the heat absorption capacity coating for selective absorption of sunray being added to collector metal pipe by magnetic control sputtering vacuum coating process, increase the service life.
Accompanying drawing explanation
Fig. 1 is overall structure figure;
Fig. 2 is fragmentary cross-sectional view;
Described in Fig. 1 to Fig. 2, outer glass tube (1), collector metal pipe (2), ring of cooling down (3), can cut down becket (4), 10 flint glass Fs (5).
Detailed description of the invention
A kind of metal-glass head seal thermal-collecting tube, comprise outer glass tube (1), collector metal pipe (2), to cool down ring (3), becket (4) can be cut down, described collector metal pipe (2) is arranged in outer glass tube (1), the two ends of collector metal pipe (2) respectively roll welding are connected to and can cut down becket (4), the two ends of outer glass tube (1) reach sealing function in glass respectively by 10 flint glass Fs (5) and one end sealing by fusing that can cut down becket (4), moreover, again because the coefficient of expansion of 10 flint glass Fs is with the expansion coefficient similar that can cut down becket, can not produce because cold and hot expansion causes outer glass tube to break.Be vacuum layer between collector metal pipe (2) and outer glass tube (1), ring (3) of cooling down is fixed on the two ends of the collector metal pipe (2) in vacuum layer, forms coating for selective absorption to sunray at the outer surface of collector metal pipe (2) by magnetic control sputtering vacuum coating process.Cool down ring (3) because be arranged in vacuum layer, the gas that collector metal pipe (2) and outer glass tube (1) discharge can be absorbed, the vacuum state in available protecting vacuum layer.
Described collector metal pipe (2) is sus444 ferrite stainless steel pipe, forms coating for selective absorption to sunray at the outer surface of collector metal pipe (2) by magnetic control sputtering vacuum coating process.
The side sectional shape of described cut down becket (4) is S type, and being arranged to S type has good retractility, greatly alleviates the tension force and pulling force that bring owing to expanding with heat and contract with cold.
Claims (3)
1. metal-glass head seal thermal-collecting tube, comprise outer glass tube (1), collector metal pipe (2), to cool down ring (3), becket (4) can be cut down, it is characterized in that, described collector metal pipe (2) is arranged in outer glass tube (1), the two ends of collector metal pipe (2) respectively roll welding are connected to and can cut down becket (4), the two ends of outer glass tube (1) are connected with one end sealing by fusing that can cut down becket (4) respectively by 10 flint glass Fs (5), be then vacuum layer between collector metal pipe (2) and outer glass tube (1), ring (3) of cooling down is fixed on the two ends of the collector metal pipe (2) in vacuum layer.
