Description
Technical field
The utility model relates to a kind of air cooling device, more specifically to a kind of finned tube air cooling device.
Background technology
Present most finned tube air cooling device all adopts pipe and circular fin, and material is steel pipe steel disc or copper pipe copper sheet etc.Circular finned tube generally adopts nest plate expanded joint formula, iron chains chip, rolls chip etc. around chip, weld tabs formula, bimetallic.Because air cooling device starts, is stopping, can produce the thermal shock phenomenon when thermic load instability or meteorological condition cataclysm, above-mentionedly, weld tabs formula and bimetallic all may fin and interbank thermal contact resistance be increased and the decline of device heat transfer property when the long-time running because thermal shock causes fin loosening except that rolling the chip.And, the general fork row triangular in shape of circular finned tube, tube bank is difficult to fix, and its fixed frequency is low, and resistance to shock is poor.Simultaneously, because air-flow flows along triangle fork row's pipe cross section, a heat exchange dead band is arranged carrying on the pipe cross section of airflow direction, in order to take away the heat in heat exchange dead band, must strengthen the air quantity and the pressure head of blower fan, fluid resistance is big, fan operation energy consumption height.There is the vortex in pipe cross section back of the body airflow direction heat exchange dead band in addition, easy incrustation, and sealing factor is big.And because pipe girth and sectional area ratio are little, the heat exchange radius is big, so heat exchange efficiency is lower.
Summary of the invention
Main purpose of the present utility model is in order to improve the conductivity of heat of above-mentioned existing circular finned tube, promptly to improve its heat exchange efficiency.
To achieve the above object, the technical scheme that the utility model adopted is: it comprises the framework of two tube sheets that are parallel to each other that link together and two piece side plates formations being parallel to each other vertical with two tube sheets, be positioned at the tube bank that constitutes by finned tube of framework, be connected deep bead and the support bar that is connected the fixedly tube bank on the side plate on the tube sheet, be positioned at the cross section ovalize parent tube on the finned tube, the rectangular fin that is connected with tinning on the parent tube or galvanizing.
In order to strengthen its finned tube resistance to shock, on finned tube, be equipped with the vibrationproof card.
Described tube sheet one end is the side plate that is fixedly connected, the other end another side plate for flexibly connecting.
As above-mentioned structure, by the tube bank cooling, cooling water flow dispels the heat through finned tube high temperature air from top to down.
Using the beneficial effect that finned tube air cooling device of the present utility model produced is:
1. because the cross section ovalize of parent tube on the finned tube in the finned tube air cooling device of the present utility model, therefore the fluid in the parent tube can reach turbulence state when hanging down flow velocity, strengthened heat transfer property, therefore finned tube air cooling device of the present utility model is used for pump, and the pump operation energy consumption is low.
2. in the finned tube air cooling device of the present utility model, by the support bar that is connected on the side plate whole tube bank is fixed, and on every finned tube, the vibrationproof card is housed, thereby tube bank intrinsic frequency height, resistance to shock is good.
3. because air-flow is mobile along the elliptical tube major cross-sectional axis direction of in-line arrangement, the little air drag of gas-flow resistance descends 15～25%, therefore is used for blower fan, can make the fan operation energy consumption low in the finned tube air cooling device of the present utility model.
In the 4 finned tube air cooling devices of the present utility model because air-flow flows no heat exchange dead band, no vortex, and sealing factor is little along the tubular major axis of ellipse.
5. in the finned tube air cooling device of the present utility model, because the cross section ovalize of parent tube, the ratio of oval girth and sectional area is big, and the heat exchange radius is little, and does not have the heat exchange dead band, so the heat exchange efficiency height, and the outer film heat transfer coefficient of parent tube improves about 25%.
6. the parent tube in the finned tube air cooling device of the present utility model is connected by tinning or galvanizing with rectangular fin, and promptly the surface is tinning or galvanizing, even one deck nickel phosphorus compound overcoat is arranged, thereby the resistance to corrosion height, longer service life.
7. be connected the deep bead on the tube sheet in the finned tube air cooling device of the present utility model, can prevent the short circuit of wind, the air cooling better effects if.Tube sheet and side plate one end (left side in this example) are for being fixedly connected, and the other end is for flexibly connecting.The side plate that flexibly connects is provided with the hole, and straight pin corresponding with it arranged on tube sheet.Tube bank has been avoided temperature stress because the thermal expansion that produces that heats up can be free to slide on the right side when making operation like this.

The specific embodiment
Be further described below in conjunction with the structure of accompanying drawing the utility model finned tube air cooling device:
Shown in Fig. 1,2,3,4, the utility model comprises the framework of two tube sheets that are parallel to each other that link together 1,8 and two block side plates being parallel to each other 4 formations vertical with two tube sheets, finned tube 11 in framework between two tube sheets, be connected deep bead 12 and the support bar 9 that is connected on the side plate 4 on the tube sheet, wherein finned tube 11 is connected by the welding or the tube side formula that rises with tube sheet 1,8.
Described tube sheet 1 one sides are the side plate 4 that is fixedly connected, opposite side another side plate 4 for flexibly connecting.In the present embodiment, a side of tube sheet 1 (left side on the drawing) is fixedlyed connected with side plate 4 formations with screw 2, packing ring 3; The opposite side of tube sheet 1 (right side on the drawing) is fixed with straight pin 7, can be enclosed within trepanning on the straight pin 7 with being equipped with on the side plate 4 that this side (right side on the drawing) is connected.Borehole jack is enclosed within on the straight pin 7, constitutes the opposite side of tube sheet 1 and the flexible connection of another side plate 4.Therefore, when restraining the thermal expansion that produces owing to intensification, can be free to slide, avoid temperature stress in this side.Support bar 9 is by bolt 5, and packing ring 6 is linked together with side plate 4, thereby constitutes the good framework of a rigidity.Deep bead 12 is associated in tube sheet (as shown in Figure 4) by bolt 13, packing ring 14.In the present embodiment finned tube be arranged as rectangular arranged, and whole tube bank is fixed by the support bar 9 that is connected between the side plate 4.
