Abstract
The present invention relates to a novel method for producing a heat absorption plate bar of a solar energy flat plate heat collector. The plate bar is processed by a method that a thin metal band is formed by cold bending and is assembled and rolled with a heat collecting pipe. The heat collecting pipe (a copper pipe) has no extension or deformation, and aluminum fins are exposed out of both ends of the heat collecting pipe, and can be directly welded on a water collecting pipe. The present invention adopts a method for processing the rolled metal plate bar, which can reduce the leaky ratio of the water pipe, reduce the material consumption, and reduce the cost.
Description
Background technology
The present invention relates to a kind of production and processing method of heat absorption lath of novel plate solar collector plate core.
Technical field
At present, what plate solar collector was most widely used both at home and abroad is the copper-aluminum composite board core, the absorber of this plate core is the copper-aluminum composite board bar, form through rolling as the metal tube of the described copper-aluminum composite board bar of Chinese patent CN1069211A by a layer of metal lath and a flattening, make the two contact-making surface reach metallurgical binding, blow into from the metal tube that presses with compressed air at last, form the rhombus runner.Advantages such as this processing method has thermal efficiency height, and the life-span is long; But the heat absorption copper pipe of water flowing in the copper-aluminum composite board bar will pass through composite rolling (lengthening coefficient is bigger), and the production process copper pipe will through flatten earlier, inflation again, this process has increased the ratio of copper pipe seepage, has also increased the percent defective of production process, has promptly increased cost.This technology has determined that copper pipe has become diamond pattern in the composite slats, and can not be circular.Thereby cause lath and being connected of collector pipe inevitably will take a centre part; This must be finished an interface by the twice weld bond, and because the fusing point low (fusing point of aluminium is 660 ℃, and the fusing point of copper is 1083 ℃) of aluminium, this twice weld bond must adopt two kinds of scolder welding respectively.Welding between copper-aluminum composite board bar and the rhombus tubule at present can only be adopted soldering.Fact proved no matter be to use life-span, intensity, anti-leakage, this one soldering is all not as good as the no silver soldering between copper and the copper; Therefore copper-aluminum composite board core use at the scene, especially for the forced circulation system, the seepage that happens occasionally phenomenon.
Summary of the invention
Purpose of the present invention is exactly for the heat absorbing element one of designing a kind of plate solar collector rolls the new processing method that alloy belongs to lath, both can reduce the ratio of water pipe seepage, reduces the percent defective of production process again, reduces cost.
New process processing completely that neoteric metal has rolled the plywood strip adoption, forming two and half laths (rolling two wings of plywood bar) that roll the plywood bar is that the metal strip cold roll forming is rolled the method for closing with the thermal-collecting tube assembling again, thermal-collecting tube (copper tube) does not extend and distortion, and every lath two ends endothermic tube exposes and can directly be welded on the collector pipe.
Description of drawings
Describe design feature and the processing method that the copper aluminium of composition heat-absorbing plate core involved in the present invention rolls the plywood bar in detail below in conjunction with accompanying drawing.
Accompanying drawing 1: copper aluminium rolls the plywood bar
Accompanying drawing 2: copper aluminium rolls plywood bar processing master operation
Accompanying drawing 3: copper aluminium rolls the plywood core
The specific embodiment
As shown in Figure 1, copper aluminium rolls the plywood bar and is made up of two aluminium matter, half lath 1 and a thermal-collecting tube 2.Wherein, aluminium matter half lath is to adopt the special equipment clod wash to be processed into to be with semicircular fin 1, and the semicircle radius conforms to the thermal-collecting tube radius, and the length of thermal-collecting tube exposes two ends greater than half lath.Then as shown in Figure 2, two and half laths 1 and thermal-collecting tube 2 are assembled into copper aluminium and roll plywood bar blank, and blank once rolls synthetic qualified copper aluminium through the zap-lop machine group of special use and rolls the plywood bar.Fig. 3 rolls plywood bar 3 by copper aluminium to roll the plywood core with the copper aluminium that collector pipe assembles out.The 4th, can be directly and the collector pipe of thermal-collecting tube welding.
Copper aluminium of the present invention rolls and closes not only thermal efficiency height of plate core that bar is processed into, and is aesthetic in appearance, and in withstand voltage, leakproof with all than composite plate core remarkable advantages is arranged on the life-span.The aluminium wing that rolls the plywood bar adopts the cold-bending molding technology manufacturing, can adopt thin aluminium strip production, and thermal-collecting tube can be designed to optimum tube diameter, so materials are fewer and reduced cost.It is to adopt to be different from the superior product of new generation that common lath processing method is produced that copper aluminium of the present invention rolls the plywood bar.
The present invention is in concrete enforcement, and thermal-collecting tube is qualified copper tube, requires length scaling and two-port not to be with burr.Half lath can be a thin aluminium strip, also can be other thin metal.The lath blank (rolls plywood bar two wings partly) and rolls neat waveform decorative pattern on half lath when the zap-lop machine group is rolled synthetic copper aluminium and rolled the plywood bar, to increase endotherm area and increase rigidity.And the thermal-collecting tube two ends expose the aluminium wing, can directly be welded on the collector pipe easily.
Claims (3)
1, a kind of production and processing method of plate solar collector heat absorption lath, be included in and place thermal-collecting tube (2) between two duplicate half laths (1) through rolling incorporated lath, it is characterized in that: earlier the metal sheet band fixed length is cut out, form half lath (1) of band semicircle through cold roll forming, in the interior circle that two halves lath (1) assembling forms, put into round thermal-collecting tube (2), make pipe, half lath closely roll integrator then.
2, the production and processing method of plate solar collector heat absorption lath as claimed in claim 1 is characterized in that: the length of described thermal-collecting tube (2) makes two ends respectively stretch out one section formation coupling part greater than the length of half lath.
