Other 2 semi arch plate edges of boards limit to the 1～1.5mm that turns up; Wherein one at the two ends 10mm that lets the hair grow, and outwards the limit height that stretches of punching is that 1～2mm is convenient to install the heating installation import, the heating outlet joint; The semi arch plate that is communicated with the installation heating tube merges; It is consistent that the plate face contacts the bilateral alignment of two edges of boards, pinches the limit and be connected into pipe from molten face bonding method straight weld, constitutes pipe shape header connectivity structure; Pipe header end socket outward flanging 4～7mm is embedded in 4 ports of pipe header, and the end socket edges of boards coincide consistent and connect, pinch the straight weld of limit self-dissolving planar process with the bilateral snap to none of circular arc edges of boards gap and are connected into overall structure in succession.
The utility model is the concrete structure that example is explained header heating tube binary channels heat transfer heat exchanger with D shape header:
1, the orifice plate of D shape header is communicated with the inside stretchable holes of outer tube caliber size punching limit height 2～2.5mm according to heat supply; Orifice plate both sides outside flanging height 2～3mm; C shape plate compacting reinforcement 4 roads; Heat supply is communicated with outer tube not to be had the gap and inserts in the D couplet case orifice plate stretchable holes, orifice plate stretchable holes limit and heat supply be communicated with outer tube port limit coincide consistent, pinch limit self-dissolving downhand welding method girth welding connection.To be communicated with back integral body be movable to straight tube in running water endothermic tube, the running water direct-connected siphunculus that absorbs heat, heat supply, and the thermal expansion shrinkage can freely be stretched, the interior system of minimizing cold fluid heat expansion water leakage ratio.The footpath does not have after the pressure test and leaks to qualified after the running water endothermic tube system connectivity, is stuck in C shape header plate on the orifice plate, and the limit of the outer folding of orifice plate and the two edges of boards of C shape edges of boards align and coincide consistently, pinch the limit and melt downhand welding method vertical masonry joint certainly and be welded to connect.
2, limit, running water endothermic tube both sides pipe is 45 according to pipe diameter two ends to cutting in the other direction; One termination is imported and exported gas thread silk head with running water and is connected; In addition termination and the running water direct-connected siphunculus that absorbs heat is communicated with; Other running water endothermic tube two ends is 45 to cutting in the other direction, and the two ends corresponding surface all is exterior angles, and running water absorbs heat, and the diameter two ends is equidirectional all to be 45 to incised to direct-connected siphunculus with managing according to the running water endothermic tube; Logical in succession with the butt welding of running water endothermic tube, seal of tube welding connection communicates with header in running water absorbs heat direct-connected siphunculus exterior angle end punching insertion heating tube.
3, the running water endothermic tube also can an end be held into the direct-connected siphunculus welding of absorbing heat of curved (the holding back bending) other end of U-shaped and running water and is communicated with, reduces welding point and reduces water leakage ratio saving energy minimizing expense.
4, D couplet case head plate outward flanging height is 2～2.5mm; Be embedded in the D couplet case 4 termination ports; End socket edges of boards and bilateral snap to none gap, D couplet case port limit coincide consistent, and connect and pinch the limit around D couplet case port and be welded to connect from melting the argon arc welding of downhand welding method circumferential weld.
The inventive point of the utility model: the utility model application is that the renewal of prior art is created, and has improved product with compact structure property, under present low-temperature heat supply situation; Effectively utilize hot fluid, promptly increase heat transfer area in the unit volume, improved rate of heat transfer; Dwindle running water endothermic tube pipe cavity diameter; In thinner running water endothermic tube pipe cavity center, insert that pipe has dwindled heating radius in the stainless steel heat supply, attenuate cold fluid zone of heating thickness; Be the heating of annulus state, it is very fast that zone of heating thickness diameter is no more than 3～4.5mm heat conduction.The running water direct-connected stilette running water endothermic tube caliber that absorbs heat is little 1.9～2.3 times; In heating tube shell side passage, many external shunts plate is installed again; Its objective is in order to strengthen shell-side fluid speed, make heat, cold two kinds of Hydrodynamic turbulence degree aggravation, to improve the fluid convection heat transfer coefficient; Constituted cold fluid two partition convection heat transfer' heat-transfer by convection in toroidal cavity, formation heat, cold two kinds of fluids are go in ring triple channel adverse current or mixed-flow circulation heat transfer structure.Exchange output running water hot water and the synthermal successive stream of hot fluid inlet water temperature degree do not have temperature difference.The utility model conducts heat to compare with existing and patented technology single file passage single wall and has improved 3 times heat-transfer effect, has outstanding substantive distinguishing features and obvious improvement.And reduced manufacturing cost, the pickling of stainless steel fouling ability, life of product is long, belongs to upgrading substituting innovative product.
