Abstract
The utility model relates to a braze welding fixing device, in particular to a flat tube aluminum fin heat transfer tube braze welding fixing device. The braze welding fixing device mainly solves the technical problem that an existing braze welding fixing device is heavy and has low braze welding quality. The technical scheme of the utility model is that the flat tube aluminum fin heat transfer tube braze welding fixing device comprises an upper lateral plate, a lower lateral plate and a middle parting stop, wherein two heat transfer tubes are fixed between the upper lateral plate and the lower lateral plate, the two heat transfer tubes are separated by the middle parting stop, the lateral plate is welded into a hollow frame through a stainless square tube, the lateral plate is welded by two rows of transoms and a plurality of vertical crosspieces, and clamping screw bolts which fasten the two lateral plates are arranged on the upper end and the lower end of the vertical crosspiece of the lateral plate. The fixing device is mainly used to fix heat transfer tube braze welding aluminum fins.
Description
Technical field:
The utility model relates to a kind of soldering clamping device, particularly a kind of flat tube aluminum fin recuperator tube soldering clamping device.
Background technology:
The general zinc-plated elliptical tube steel fin heat exchange pipes that adopt of the heat exchanger tube of power plant's air cooling device more, but flat tube aluminum fin recuperator tube has the trend that substitutes zinc-plated elliptical tube steel fin heat exchange pipe now, flat tube aluminum fin recuperator tube is compared with zinc-plated elliptical tube steel fin heat exchange pipe, its advantage: in light weight, the exchange capability of heat of relative unit weight increases to some extent.Supporting with it frameworks etc., weight alleviates greatly, thereby has saved manufacturing cost.Only there are several companies such as U.S. Si Bike, German GEA, Chinese Harbin Air-Conditioning Co., Ltd in the company that produces the flat tube aluminum finned tube at present.Maintaining secrecy separately in the manufacturing technology aspect, bottles up.
The utility model content: the purpose of this utility model provides a kind of flat tube aluminum fin recuperator tube soldering clamping device, mainly solves existing soldering clamping device heaviness, technical problem that brazing quality is not high.
The technical solution of the utility model is: a kind of flat tube aluminum fin recuperator tube soldering clamping device, comprise epipleural and lower side panel and middle spacer bar, two heat exchanger tubes of clamping between epipleural and lower side panel, two heat exchanger tubes are separated by middle spacer bar, side plate is welded into sky frame type by the stainless steel square tube, described side plate is welded by two horizontal row shelves and some perpendicular shelves, and the perpendicular shelves of side plate are provided with the fixedly fishbolt of biside plate in two ends up and down.
The two ends of middle spacer bar are 45 ° of oblique angles.
The beneficial effects of the utility model are: flat tube aluminum fin recuperator tube is made up of aluminium fin and the single face flat tube of aluminizing, the advantage of aluminium fin be in light weight, thermal conductivity good, the advantage of steel flat-tube is the intensity height, but the welding difficulty of steel and aluminium.The utility model is owing to adopt the soldering clamping, make that the aluminium coated and the aluminium fin of flat tube are integrally welded, the utility model is when carrying out soldering, side plate is contained in two planes up and down of fin, and the two ends of side plate are by bolting, by regulating the seamless applying of a side that the bolt thrust makes fin and solder and flat tube, make brazing quality be promoted, and side plate adopts frame-type, makes the weight of clamping device alleviate greatly, is convenient to clamp.

Among the figure: 1-flat tube, 2-aluminium fin, 3-solder and brazing flux, 4-side plate, 5-fishbolt, 6-crosspiece, the perpendicular shelves of 7-, spacer bar among the 8-.
The specific embodiment:
With reference to accompanying drawing 1,2,3, a kind of flat tube aluminum fin recuperator tube soldering clamping device, comprise upper and lower side plate 4 and middle spacer bar 8, two heat exchanger tubes of clamping between epipleural and lower side panel, two heat exchanger tubes are separated by middle spacer bar 8, side plate is welded into sky frame type by the stainless steel square tube, and described side plate is welded by two horizontal row shelves 6 and some perpendicular shelves 7, and the perpendicular shelves of side plate are provided with the fixedly fishbolt 5 of biside plate in two ends up and down.Heat exchanger tube length is 9-10m, during clamping up and down side plate link to each other with middle spacer bar spare part, and total length is approximately greater than heat exchanger tube length.Keep flat lower side panel during clamping on workbench, the quantity of lower side panel is determined by heat exchanger tube, is generally 8-10 spare.Locating piece is arranged on the platform, under the guiding of locating piece, one of lower side panel is piled up neat being aligned near another part, pile up aluminium fin 2, solder and brazing flux 3, flat tube 1, solder and brazing flux 3, aluminium fin 2 on it successively, place the middle spacer bar 8 that two rows are made by square tube thereon, its position is apart from fin outside 5mm, and its end is 45 ° of oblique angles, spacer bar docks into R-joining in alternate, and the rule is joined, because side plate is different with parting bead length up and down, natural joint interlaces.According to the clamping method of first heat exchanger tube, on middle spacer bar, load onto second heat exchanger tube, second heat exchanger tube installs and refills epipleural, puts on fishbolt 5, makes the fit-up gap of welding base metal reach the regulation requirement by adjusting nut.Through the continuous-moving type nitrogen-protective soldering, the soldering qualification rate reaches more than 99%.
