Description
Technical field
The utility model relates to a kind of flat-plate solar collector tube sheet conductive structure.
Background technology
Flat-plate solar collector is a critical piece of solar water heating system, bearing and collecting the function that absorbs heat, how the heat of collecting plate being sent in the medium in medium runner rapidly and efficiently, and then being sent to attemperater, is the important topic of always studying.Flat-plate solar collector endothermic effect and relationship between quality are to the Performance and quality of whole system; Existing flat-plate solar collector tube sheet heat-absorbing structure is mainly the direct welding of collecting plate (plated film aluminium sheet) and medium runner (copper pipe), and welding manner adopts ultrasonic wave or laser weld (accompanying drawing 1-3); There is series of problems in this structure: 1, tube sheet contact-making surface is little, and tube sheet heat transfer efficiency is low; 2, because medium runner is general, adopt thinner copper pipe (0.4-0.5mm), in laser or supersonic welding termination process, inevitably cause the loss of copper pipe, make copper pipe become thinner, cause and can not bear for a long time higher operating pressure; 3, because solar absorber plate (aluminium sheet) and medium runner (copper pipe) belong to different metal materials, both weld together easy formation electrochemical corrosion, easily cause the corrosion of solder joint sealing-off or copper pipe; Above problem is directly connected to performance and the quality of whole solar water heating system.
For addressing the above problem, Chinese patent ZL201120154593.9 provides the composite casing type flat-plate solar collector that a kind of flow-path tube section is inverted "Ω"-type, wherein medium runner is composite bushing, when fabrication and installation, there is very large problem in such structure, very strict to the dimensional requirement of medium runner and outer tube, if the external diameter part of medium runner is more than or equal to the internal diameter with outer tube, be difficult to the two to be nested together, if the external diameter part of medium runner is less than the internal diameter of outer tube, cause both fully not contact, heat-conducting effect declines.The flat-plate solar collector that Chinese patent ZL201120154575.0 flow-path tube section is inverted "Ω"-type, the inverted "Ω"-type pipeline that wherein medium runner is formed in one, such pipeline has increased the cost of solar thermal collector, and heat collector is of a great variety, make global formation " Ω " type pipeline kind too much, be therefore difficult to apply.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of flat-plate solar collector ohm tube sheet conductive structure, this structure can be applied to strip-type flat-plate solar collector, also can be applicable to whole board-like flat-plate solar collector, more flexible for the processing of product.
The utility model is mainly comprised of solar heat-collection plate, medium runner, solving the technical scheme that its problem adopts is ohm heat conduction ring that also comprises mounting medium runner, ohm heat conduction ring is " Ω " type, mainly arc ring and two flanks, consist of, the internal diameter of arc ring equals the external diameter of medium runner; Medium runner clip is in ohm heat conduction ring, and ohm heat conduction ring two flanks and solar heat-collection plate weld together.
According to the utility model, the contact area of described medium runner and described ohm heat conduction ring and solar heat-collection plate is not less than 80% of medium runner external surface area.
According to the utility model, described medium runner is aluminum pipe or copper pipe.
According to the utility model, described ohm heat conduction ring is aluminum material.
Adopt the utility model, solar heat-collection plate absorbs sunlight and is converted into heat energy, by ohm heat conduction ring, is passed to the medium in medium runner, and medium temperature raises, and by external force or thermal convection current, is sent to attemperater; Like this due to medium runner with ohm heat conduction ring and and solar heat-collection plate have more than 80% contact-making surface, heat absorption conductive efficiency increases greatly; And owing to there is no the direct welding of copper pipe and aluminium base, neither destroy copper pipe and do not form again electrochemical corrosion, the quality stability of whole system is played to vital effect.Ohm heat conduction ring can adopt aluminum material, and heat transfer efficiency is high, and has certain elasticity.Can adopt aluminium sheet blanking rear mold to be stamped to form, the direct extrusion modling of Ye Ke aluminium section bar producer, cost is low, and fabrication and installation are very convenient; Because ohm heat conduction ring is single welding, the flat-plate solar collector of applicable various structures.
