Abstract
A red copper plate tube heat collecting device produced by an explosion welding method in a solar flat plate liquid heat collector is characterized in that a pressed red copper plate 1 and a plurality of red copper tubes 2 are subjected to explosion welding under the support of a thick carbon steel backing plate 4 with a semicircular groove, the welding area is large, the welding strength is high, and the heat conducting performance and the corrosion resistance are improved. The welding part has no defects of burning loss, cracking and the like, and is easy to realize batch production.
Description
Technical field
The utility model is the copper plate pipe heat collector of producing with explosion welding method in a kind of plate solar liquid for heat collection device, belongs to the solar water heater field.
Background technology
Plate solar liquid for heat collection device is the most widely used solar heat element in the whole world; brass roll welding plate as U.S. Olan company; the pipe of Revere company-bar formula brass collector plate is produced in batches; because red copper has high thermal conductivity factor and resistance to corrosion; the thickness that is welded into only is the red copper absorber plate about 0.5mm; duct member is the highest in all solar thermal collectors aspect the virtual value of unit daylighting area and life-span; just the resistance of copper plate pipe is too little; can not produce in batches with the roll welding method; adopt the argon shield welding also easily to burn because of tube wall is too thin; yielding; easy to crack, seam cost and percent defective are all very high.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned interconnection technique, adopts explosion welding method to realize the solid-state welding of copper plate pipe.
The purpose of this utility model is achieved in that copper plate 1 stamps out semicircle groove by copper tube external diameter and tube pitch from advance before explosive welding, and the big 0.4～0.6mm of groove radius ratio tube wall radius is at its non-solder side stopping off 8; Thick carbon steel backing plate 4 is also pressed copper tube external diameter and tube pitch from pre-processed semicircle groove, separant coating before the big 0.4～0.6mm of groove radius ratio tube wall radius, placing plate pipe; Copper tube 2 is filled in the groove of clear water and stifled tight rearmounted backing plate 4, buckles copper plate 1 behind the position to be welded of cleaner plate pipe, lays explosive frame 5, lay explosive 6, detonator 7 by the required dose of connecting portion, promptly finishes welding after ignite the place of safety.
This welding is that the seam area is big in the moment of explosive charge local deformation that produces and the solid-state welding that fuses realization, and the weld strength height has improved heat conductivility and resistance to corrosion; The welding position does not have scaling loss, pore-free, nothing cracking vestige, easily, realizes producing in batches; Not only avoided easily the burning of argon shield welding, yielding, easy to crack, shortcoming that seam cost and percent defective are all very high; Equipment investment also far below the roll welding production line of brass collector plate, promptly can realize that with less investment heat conductivility and resistance to corrosion are better than the batch process of the red copper collector plate of brass.
The utility model is provided by following examples and accompanying drawing.
Description of drawings
Fig. 1 produces copper plate pipe heat collector schematic diagram with explosion welding method.
The specific embodiment
With reference to Fig. 1, the copper plate pipe heat collector of tube pitch in 1 * 1.1 meter plate solar liquid for heat collection device of 100mm made with the copper tube 2 of the copper plate 1 of 1100 * 1300 * 0.35mm and 9 external diameter 10mm, wall thickness 0.5mm, long 1100mm, and concise and to the point operation is:
1, on 1.1 * 1.2 meters carbon steel backing plates 4 of thick 30mm, processes 9 semicircle grooves from 100mm, groove radius 5.4～5.6mm by tube pitch.With the following punch die of this backing plate replacement punching press copper plate groove, on copper plate 1, stamp out the semicircle groove of 9 radius 5.4～5.6mm, its reverse side pitching protective layer 8.
2, the whole place of thick carbon steel backing plate 4 horizontalizations, groove surface up, oiling separation layer before the placing plate pipe.3, an end stops up tightly after copper tube 2 shapings of 9 external diameter 10mm, wall thickness 0.5mm, long 1100mm, fills in the semicircle groove of clear water and stifled tight rearmounted backing plate 4, buckles copper plate 1 after to be welded of the cleaner plate pipe, presses the required TNT consumption of connecting portion 0.1g/cm
2Or rock explosive amount 0.5g/cm
2Lay explosive frame 5, lay explosive 6, detonator 7, after ignite the place of safety, finish welding.
Claims (4)
1, a kind of copper plate tube solar heat-collecting device of explosive welding comprises copper plate 1, copper tube 2 and connects 3, it is characterized in that the plate pipe is formed by connecting by the solid-state solder side that adopts explosion welding method to form.
2, the copper plate tube solar heat-collecting device of explosive welding as claimed in claim 1, it is characterized in that described copper plate 1 before explosive welding by copper tube external diameter and tube pitch from pre-processed semicircle groove, the big 0.4～0.6mm of groove radius ratio tube wall radius.
