Abstract
The ellipse tube-arraying type heat exchanger for the heat transfer among materials of the utility model belongs to the heat-exchanging system, which is mainly characterized in that the ellipse tube array is used to replace the existing core, the ellipse tubes are provided with definite intervals and are welded on both ends, and a tube sheet connected with the ellipse tubes is installed in a casing together with the tubes. The utility model has the advantages of simple structure, simple manufacturing process, low cost and convenient operation, which reduces 90% of the workload of weld joint and improves 20% of the heat exchange area and the thermal efficiency ratio comparing with those of the lamella heat exchangers.
Description
A kind of elliptical tube row formula heat exchanger that is used for heat transmission between the material belongs to heat-exchange device.
Before the utility model is made, in industrial and agricultural production, in industries such as chemical industry, oil, machinery, papermaking, pharmacy, food, a kind of technology firing equipment of extensive use generally adopts shell-and-tube heat exchanger and lamella heat exchanger, and the lamella heat exchanger comparatively approaching with the utility model mainly adopts plate bundle and housing two parts to form.The plate of plate bundle is shaped difficult, and the welding job amount is big, the seam welder plants, and requirement still can not guarantee, easy deformation, shaping difficulty after the welding.
The purpose of this utility model provide a kind of simple in structure, easily manufactured, cost is low and can increase heat exchange area, improve the elliptical tube row formula heat exchanger of the thermal efficiency.
The utility model elliptical tube row formula heat exchanger principal character is to adopt elliptical tube to arrange by certain spacing, and the two ends welding combines, and the elliptical tube displacement is for original plate bundle.Elliptical tube row be connected with tube sheet, is installed in the housing.
Description of drawings:
Fig. 1 is the utility model elliptical tube row formula heat exchanger front view:
Fig. 2 is the utility model elliptical tube row formula heat exchanger right view:
Fig. 3 is the utility model elliptical tube row front view:
Fig. 4 is the utility model elliptical tube row mansion view:
Embodiment during following the utility model elliptical tube row formula heat exchanger is incited somebody to action in conjunction with the accompanying drawings is further described:
Elliptical tube can adopt standard series elliptical tube (flat tube) to make, and the length of the semi-minor axis of elliptical tube, major semiaxis, wall thickness, pipe range, two ends welding is by the pressure of heat exchanger use occasion, and temperature, required heat exchange area factor determine.Long as length, can increase the weld number in the centre, be to arrange two ends by the elliptical tube of certain-length by certain spacing to weld respectively with rigidity, the elliptical tube row 4 who guarantees whole elliptical tube row.Elliptical tube is arranged 4 two ends and is connected with tube sheet respectively, is installed in the housing 5 then and is welded.Shell side is imported and exported adapter 3,6 and is installed on the housing, tube side is housed on the housing right-hand member bobbin carriage 9 imports and exports adapter 8,12, pass partition 13.End is loaded onto end socket 1, the flange 2 that has been welded into one and is added sealing gasket 11 and uses bolted respectively about housing, then bearing 10 is welded on the housing.
The utility model ellipse tube-arraying type heat exchanger compared with prior art has the following advantages:
1, because the ellipse tube-arraying two ends are welded, have substituted to weld in a large number with two or several piece plate and combined. And reduced the forming process of plate, the welding job amount also reduces more than 90%.
So 2, original plate bundle is difficult to control because of the very big welding deformation of welding capacity, and the thermal deformation after the welding now overcomes substantially.
3, exist spacing because elliptical tube row goes up between elliptical tube,, all directly participate in heat transfer, so heat exchange area improves about 20% than plate bundle type at whole elliptical tube garden girth.
4, the constraint that is shaped and welds owing to plate bundle raw thickness, thus very big pressure can not be born, and elliptical tube row's elliptical tube wall thickness can increase because of the increase of working pressure, so pressure improves greatly.
Claims (3)
1, a kind of elliptical tube row formula heat exchanger that is used for heat transmission between the material belongs to heat-exchange device, and it comprises housing, bobbin carriage, tube sheet, it is characterized in that adopting elliptical tube row to be mounted in the housing with tube sheet.
2, elliptical tube row formula heat exchanger according to claim 1 is characterized in that described elliptical tube row is the elliptical tube by certain-length, arranges by certain distance, and the two ends welding combines.
3, elliptical tube row formula heat exchanger according to claim 1 is characterized in that described elliptical tube row also can adopt flat tube to make.
