Abstract
The utility model relates to a winding type radiator with high heat availability, which is made by cold rolling extrusion technique. The utility model provides a technique of sealing a tube and a fin together, the fin is formed as an 'L' shape, shutter cuts and concave convex slots are arranged on the fin, the winding shape change of the fin can be sorbed and compensated, and the metallurgy bonding of the tube and the fin can make the utility model become the winding type radiator with high heat availability. The technique can be applied without tin and chemical bonding substance on radiators, heat exchangers, bathe water heater, etc. whose tube-fin points need to be sealed together.
Description
The utility model relates to a kind of high heat and imitates the coiled pipe type radiator, and it comprises that working medium tube (hereinafter to be referred as claiming pipe), L type fin (abbreviation sheet) header, support plate, decorative panel, securing member, particularly pipe and sheet are issued to metallurgical binding in operating mode not sticking, that do not weld.
The coiled pipe type radiator of existing technology is with upright shape plate-shaped fin and pipe jointing.During winding extend in riser outside, and inner edge squeezes for contracting and produces straight shape setback, with the pipe curved surface in conjunction with the time certainly lead to the slit for contacting, reduced heat exchange effect.
For densification pipe and radiator.Existing " technique for sticking " applies on the close product serial finned type radiator is effective.Because the string sheet is a closed circular, and the winding fin is the open loop helical form, so this technology is not too suitable to coiled pipe type.
The utility model is to avoid the deficiency of above-mentioned technology, and unsuitable part makes fin be convenient to deformation and becomes strain to give under the stress tensioning operating mode and provide a kind of, with the smooth zero-gap bond of pipe, the coiled pipe type radiator that high heat is imitated.
The utility model be achieved in that band material made with the coiling machine rolling device that the L type fin that has blind window otch, tongue and groove is welded in its top or the inlay card pipe on, at this moment, roll the rubbing device closure of wheel, and change by unit head drive pipe, drag the sheet motion by pipe, three uniform and tangent with pipe rollers are arranged during coiling machine crowded attaches together and put, and following two are rolled for support roller is used for support column; Top is used for squeezing the stone roller sheet for squeezing wheel, squeezes wheel in addition not on the vertical center line of pipe, but has the inclination angle to tilt toward the rolling device direction with vertical line, and be lower than the horizontal plane of sheet.Sheet stretches automatically when the pipe rotation, and vertical edge is squeezed by guider and grinds correcting, and horizontal edge rolls under the effect of squeezing wheel and makes it become metallurgical binding with pipe.It is crowded that the vertical edge opening of sheet will absorb contracting of inner edge, and tongue and groove compensation outside stretches and extends into smooth shape, when sheet around behind scale, sealed braking rolling device, further tensioning sheet, after sheet is soldered on the pipe, the back cuts off.Processing according to this goes round and begins again.
The utility model just will found shape winding fin and change the L type into, and be shaped on the blind window otch on L type fin, so both increase the area of pipe and sheet combination, be convenient to the deformation of sheet again, needn't weld simultaneously, and sintering, bonding filling just can reach driving fit.And coiling machine can be installed on the vertical planker of engine lathe, collector, sheet be machined in a machine, once finish very easy.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is the high hot view of imitating the coiled pipe type radiator that the utility model proposes.
Fig. 2 is L type fin figure.
Fig. 3 is Ω type fin figure.
Fig. 4 is coiling machine figure.
Imitate the details of the concrete structure of coiled pipe type radiator and special-purpose coiling machine according to the high heat that the utility model proposes below in conjunction with description of drawings.
(12) among Fig. 1 are header, (11) be pipe, (10) be L type fin, (9) be the groove of tube-surface, (8) be cassette tape, (7) be decorative panel, (6) be the flanging of decorative panel, (5) be support plate, (4), (3), (2) be respectively the corrugated plate that is provided with in the pipe, contact irregular that gets up, flight, (1) is securing member, sheet (5) is used to support and the fixing pipe of winding fin, the water inlet of pipe (9), delivery port is shaped on all the other heads of screw thread and links with the incavation of header (12) or U type elbow or other shape, the corrugated plate (4) in the pipe, (3), (2) can make working medium multidirectional mobile, increase heat and distribute.The flanging of decorative panel (6) is connected on the support plate with securing member, has so just made high heat and has imitated the coiled pipe type radiator, and cassette tape (8) squeezes sheet (10) during only for specific (special) requirements and is embedded in the groove (9).
A is a vertical edge among Fig. 2, Fig. 3, and B is a horizontal edge, and the A-A section is represented the situation of tongue and groove and otch.
(25) among Fig. 4 are the band bin, initial external force promotes band material (26) and goes into rolling device (21), a pair of gear of its axle (27) transmission (22) and a pair of wheel (23) that rolls, be made into Fig. 2, L type shown in Figure 3, the Ω matrix, sheet enters guide device (20), effective chuck (14) chucking, with tailstock (18,) feeling relieved holds out against, Knurling device (28) is handled tube-surface, and sheet is at weldering or inlay card Guan Shanghou, and rolling device (21) is cancelled external force, and friction mechanism closure, change by unit head (13) drive pipe, by rotation of pipe racks moving plate and stretching tensioning automatically, nationality attaches together two support roller support columns putting in (19).A crowded crop rotation extruding plate, its outer rim is lower than the horizontal level of band (26), and has the inclination angle to become big cornerite that sheet is squeezed to be incorporated on the pipe, becomes metallurgical binding because the active force that support roller is arranged and squeeze wheel makes to manage with sheet.Follow away frame (24) to follow away around sheet with pipe, reach that the arrestment mechanism of closed rolling device makes sheet stop behind the scale, unit head (18) is done little precession to be made and is with after the tensioning more its weldering or inlay card to pipe.
The surface of pipe does not process, and reaches metallurgical binding equally effectively.
When sheet by around above pipe, by aforementioned assembling back covering with paint high hot coiled pipe type radiator.
Claims (1)
- A kind of high heat is imitated the coiled pipe type radiator, it comprises working medium tube (hereinafter to be referred as pipe), L type fin, header, support plate, decorative panel, fastener, particularly pipe and L type fin are issued to zero-gap bond in not sticking situation of not welding, the L type that is shaped as that it is characterized in that the fin on the pipe, L type fin giving under the stress tensioning situation in regime of elastic deformation entirely rolled its rotation on the pipe by coiling machine, and horizontal edge becomes metallurgical binding with pipe, or the crowded pipe groove that is embedded into becomes zero-gap bond.
