The specific embodiment
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As Fig. 1, a kind of skew formula finned heat exchanger that expands that draws shown in Figure 2, comprise left plate 1, right plate 2, between left plate 1 and right plate 2, be provided with heat exchanger body, heat exchanger body comprises the eight row's fins 3 that are arranged in parallel, be used for the heat exchanger tube 4 that three mobile employing aluminum pipes of cooling lime set body are made, offer on the fin 3 along spaced apart three through holes of fin 3 length directions, centre-to-centre spacing is 22mm between adjacent through-holes, relative off-centring fin 3 centers of three through holes, three heat exchanger tubes 4 pass three through holes on the fin 3 respectively and coil revolution between every row's fins 3, both sides at left plate 1 and right plate 2, the outstanding respectively left plate 1 of the comb elbow of heat exchanger tube 4 through being bent to form and right plate 2 outsides, wherein two heat exchanger tube 4 ends are connected with liquid inlet joint 5 respectively and 6, the three heat exchanger tube 4 ends of fluid joint are stopped up with argon welding.
Through-hole diameter on the fin 3 is 8.2mm, heat exchanger tube 4 diameters and through-hole diameter match, heat exchanger tube 4 is with through hole and circumferentially fits tightly shape, at utmost contact between heat exchanger tube 4 and the fin 3 and improve heat exchange area to reach, the through hole line of centres of adjacent fins 3 and vertical direction included angle A are 20 °, make heat exchanger tube 4 be the skew shape when between adjacent fins 3, coiling, dwindle the elbow radius of heat exchanger tube 4 with this.
Manufacture craft summary of the present utility model: see shown in Figure 3, qualified aluminium foil is after spurt, on the fin 3 of moulding, form three spaced through holes, as shown in Figure 4, heat exchanger tube 4 is after enlarging, three heat exchanger tubes 4 insert respectively in three through holes on the fin 3, be through " expanding die " of heat exchanger tube 4 inside by pull, heat exchanger tube 4 and fin 3 are closely linked together, bending forming then, see shown in Figure 5, at this moment, first row, the 3rd row, the 5th row and the 7th row's fin 3 are arranged on the heat exchanger tube 4 in the same way, second row, the 4th row, the 6th row and the 8th row's fin 3 are arranged on the heat exchanger tube 4 in the same way, formation is arranged on the heat exchanger tube 4 from being the shape that alternately misplaces first row's fin, 3 to the 8th row's fins 3, beat tiltedly by beating oblique frock heat exchanging device body at last, make heat exchanger tube 4 be the skew shape with respect to fin 3, the through hole line of centres of adjacent fins 3 and vertical direction included angle A are 20 °, all being in parastate between fin 3 every rows after beating tiltedly is arranged on the heat exchanger tube 4, as shown in Figure 6.The oblique frock of this dozen patents, and the patent No. is ZL200910029716.3, beats oblique frock and adopts aerodynamic force, carries out transmission by cylinder, and the comb elbow at heat exchanger body two ends is fastened on respectively in the left and right elbow draw-in groove of beating oblique frock.When opening oblique switch, cylinder is to underdrive, and the drive link driven gear rotates, the gear other end elbow draw-in groove that links to each other, therefore the elbow draw-in groove also will rotate corresponding angle, and the comb elbow that drives heat exchanger rotates corresponding angle simultaneously, realize the oblique requirement of beating of heat exchanger body.
Heat exchanger after the oblique PROCESS FOR TREATMENT of economy-combat is compared original drawing expansion type heat exchanger, has dwindled the elbow radius of heat exchanger tube 4, can arrange more heat exchanger tube 4, and it is long-pending to improve product content; And when combining between heat exchanger tube 4 and the fin 3, heat exchanger tube 4 circumferentially with between the through holes of fin 3 are circumferential for to contact entirely, long lumbar hole on the heat exchange fin of angle-inserting type heat exchanger in the past, heat exchanger tube 4 is bigger with the contact area of fin 3, improved the heat exchange area of product, and the tensioner degree between heat exchanger tube 4 and the fin 3 is also better.
