Detailed description of the invention
Flat tube adds convex closure not enlarging stove weldering formula water tank, described water tank includes flat tube 1 and header 3, two tube chambers it are provided with in described flat tube 1, in described flat tube 1, the centrosymmetry at tube chamber two ends is suppressed with convex closure 2, the convex closure 2 of described symmetrical compacting pushes up reality mutually, and with flat pipe hole interference fit, and convex closure 2 be shorter in length than the length that flat tube 1 stretches out from header 3 flat pipe hole, flat tube 1 and header 3 to weld plane complete, and make the solder side of convex closure 2 periphery and header 3 produce to press to the stressed zone of header 3 flat pipe hole wall, when making it weld intensification in stove, the direction of its deformation is the solder side being automatically affixed to flat pipe hole, reduce welded gaps.Ratio adopt traditional flared method, convex closure method flat tube and header are how the sealing reliability of furnace brazing wants height.
Described header 3 is processed by the tubulose blank of compound layer, its side is provided with the flat pipe hole with flat tube 1 seam and the aperture with side plate plug-in mounting, although product has gathered the function of multiple part, but and uncomplicated, and deducted the sealing weld seam between multiple part, improve reliability.Owing to adopting tubular structure, after the function realizing multiple part, integration, enhances rigidity on the contrary, reduces the risk leaked because of thermal deformation.
Two tube chambers of flat tube 1 in-out end are divided at least 4 import and export by described convex closure 2, the hydraulic diameter imported and exported from flat tube 1 is substantially reduced, cause that current pressure reduction strengthens at flat tube 1 import and export, flow velocity increases, for water inlet header 3, this will make static pressure in pipe rise, the uneven water flow distribution produced because of dynamic pressure is produced inhibitory action, make water-flow equation tendency average, for water outlet header 3, because the increase of flat tube 1 exit velocity makes flat tube 1 outlet increase with the current difference in header chamber, the amount that flat tube exit momentum is transformed into collector static pressure is made to increase, so that the back pressure of flat tube 1 current is increased by water outlet collector, also make water-flow equation tendency average.And for flat tube 1, water flow velocity increases at entrance, strengthening the turbulent fluctuation of current, current close, after dividing before convex closure 2, the yardstick also increasing turbulent fluctuation.Meanwhile, at convex closure 2, can produce eddy current too increases turbulent fluctuation to current below, and in flat tube 1 exit, static pressure is made to increase because pressure reduction increases, thus the cavity that after inhibiting current cooling, volume contraction produces, these changes all make heat exchange property and temperature homogeneity be improved, particularly during low discharge.
Described header 3 section then becomes flat shape, major axis maximum to be only capable of encasing flat tube 1, and short axle, under ensureing the premise that uniform fluid flow resistance is little, flattens, in order to reserve bigger heat transfer space as far as possible.
Described header 3 one end is flanged cylindric, in order to can combine with inlet/outlet pipe clip and O and seal, other end afterbody compacting seal, and punching have side plate installing hole.
