A flat fin is provided with a base pipe hole for installing a base pipe, and a rhombic slot whose back side is flanged; the base pipe and the base pipe hole can be circular or flat. The base pipe is arranged according to a fork row form; the rhombic slot is arranged in a radial type along the periphery of the circular base pipe hole. To the flat base pipe hole, three rhombic slots are arranged in equal distance along the long edge of the flat base pipe hole. The utility model has the characteristics of excellent heat transferring performance, less flow resistance loss, etc., and has the advantages of small volume, light weight, great metallic material saving, good manufacturability and low cost. The utility model is a novel core body with high efficiency for an air cooler.
Description
The utility model is a kind of high-effect continuous finned-tube bundle, mainly as the trunk (core body) of all kinds of pipe type air coolers, belongs to the thermal machine device.
Pipe type air cooler (cooler, condenser, radiator etc.) has obtained very to use widely in distiller condenser, atomic energy fast reaction reactor core portion's cooler and the production fields such as refrigeration and drying of high-power diesel engine cooling system, air cooling power station condenser, petrochemical industry.In order to obtain the air cooler that volume is less, weight is lighter and good in economic efficiency, carry out the research of air cooling technique over past ten years both at home and abroad energetically, one of them importance is exactly to seek desirable fin structure shape, strengthen the heat transfer of continuous flat fin, as domestic and international existing venetian blind type fin and serrated fin etc., but its flow resistance loss is bigger, and heat-transfer capability is not high enough under the same pump power condition.
The purpose of this utility model is to overcome above-mentioned deficiency, and provides a kind of dynamical rhombus otch continuous finned-tube bundle, and the efficient of pipe type air cooler is increased substantially.
The utility model to achieve these goals, following technical scheme is proposed: this rhombus otch finned-tube bundle, comprise flat fin and parent tube, have circle or flat parent tube hole and rhombus otch on the flat fin, corresponding circular parent tube or flat parent tube are installed in the parent tube hole, thereby are constituted continuous fin round bundle of rhombus otch or the continuous fin flat tube of rhombus otch bundle; Parent tube is by fork row arranged in form, and the rhombus otch is at flat fin back side flange, and the physical dimension of otch is: little angle is 30 °～36 °, and long-diagonal is 4～7mm.For rhombus otch fin round bundle, the rhombus otch is pressed 36 ° at central angle or 45 ° or 60 ° of arranged radiallys along pipe hole periphery on flat fin, be radiation-like, and at the mid point of the two circular parent tube hole lines of centres, vertical direction at line, two rhombus otch of symmetric arrangement, its long-diagonal (major axis) is parallel to the line of two physa pores.For rhombus otch fin flat tube bundle, the rhombus otch is along the long limit in flat parent tube hole (narrow and long rectangular), equidistantly has three rhombus otch, and its long-diagonal is parallel with long limit, and distance be 3mm, and the minor face distance that the rhombus otch stretches out flat parent tube hole is 1mm.The physical dimension of rhombus otch is: little angle is 30 °～36 °, and long-diagonal (major axis) is 4～7mm.
The utlity model has following advantage:
1. You Yi heat transfer property.Rhombus otch finned-tube bundle is used for aerial cooler, is consuming under the same pump power condition, and its coefficient of heat transfer is restrained high by 15.2%～62.0% than common plain fin.
2. less flow resistance loss.The flow resistance loss of existing achievement in research such as flap type finned-tube bundle and herringbone ripple type finned-tube bundle is restrained high by 63.5%～87.0% than the common plain fin under the same case, and that flow resistance loss of the present utility model is restrained than common plain fin is high by 56.5%～62.0%.
3. volume-diminished, a large amount of metal materials have been saved in weight saving.
4. good manufacturability, cost is low.
Concrete structure of the present utility model is provided by accompanying drawing 1～4.
Fig. 1 is the overall structure front view of the rhombus otch finned-tube bundle of band physa pore.
Fig. 2 is the integrally-built A-A view of the rhombus otch finned-tube bundle of band physa pore.
Fig. 3 is the overall structure front view of rhombus otch fin flat tube tube bank.
Fig. 4 is the integrally-built B-B view of rhombus otch fin flat tube tube bank.
Primary structure is among the figure: flat fin 1, parent tube 2, flange 3, parent tube hole 4, rhombus otch 5.
This rhombus otch finned-tube bundle comprises flat fin 1 and parent tube 2, have circular parent tube hole 4 and rhombus otch 5 on the flat fin, rhombus otch 5 is at the back side of flat fin flange 3, arrange by fork row in circular parent tube hole on the flat fin, the circular parent tube of welding in the circular parent tube hole, the rhombus otch radially is radiation-like along it along the periphery of physa pore for 36 ° by central angle and arranges, and at the mid point of the two physa pore lines of centres, vertical direction at line, symmetry is evenly equipped with two rhombus otch, and its long-diagonal is parallel to the line of centres of physa pore, and the little angle of rhombus otch is 30 °～36 °, long-diagonal is 4～7mm, as Fig. 1, shown in 2.Parent tube hole on the flat fin can be flat parent tube hole, the layout in flat parent tube hole also adopts fork row form, the long limit in flat parent tube hole is other to have three rhombus otch by equidistant, the long-diagonal of rhombus otch (major axis) parallel with the long limit in flat parent tube hole and the distance be 3mm, the distance that the rhombus otch stretches out flat parent tube hole minor face is 1mm, the flat parent tube of welding in the flat parent tube hole is shown in Fig. 3,4.The rhombus otch is arranged along the radial arrangement of physa pore or along the long limit in flat tube hole, promptly fully blocked the lasting growth in boundary layer, has strengthened fluid to the washing away of tube wall, and does not block the heat conduction of flat fin itself again; And the mobile heat transfer that all helps strengthening of rolling of the shunting action of rhombus otch flange convection cell and generation.Rhombus otch finned-tube bundle material therefor is aluminium sheet or copper, steel sheet, and tubing is steel, copper, aluminium is held concurrently can.
