Abstract
The utility model discloses a kind of power station air cooling heat-exchanging tube bundle fin double-bridge structure, it is characterised in that including fin, fin is provided with perforate and bridge opening, and fin is provided with fin reference plane, and adjacent bridge opening is located at the both sides of fin reference plane respectively on fin.Tube-bundle fins double-bridge structure provided by the utility model, the effect of air side flow-disturbing can be increased, there is higher heat exchange efficiency.
Description
Technical field
A kind of power station air cooling heat-exchanging tube bundle fin double-bridge structure is the utility model is related to, belongs to power station air cooling technical field.
Background technology
The heat-exchanging tube bundle fin of current power station air cooling system passes through opens bridge structure frequently with one side, but its structure is only in wing
Flow-disturbing effect is played in the side of piece, and does not have obvious flow-disturbing to act in opening between bridge structure for opposite side and adjacent fins, because
And heat exchange efficiency also has the space lifted.
The content of the invention
The technical problems to be solved in the utility model is：Provide a kind of high power station air cooling heat-exchanging tube bundle wing of heat exchange efficiency
Piece double-bridge structure, solve the problems, such as that the heat exchange efficiency of the heat-exchanging tube bundle fin of traditional power station air cooling system is low.
In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of power station air cooling heat-exchanging tube bundle
Fin double-bridge structure, it is characterised in that including fin, fin is provided with perforate and bridge opening, and fin is provided with fin reference plane, wing
Adjacent bridge opening is located at the both sides of fin reference plane respectively on piece.
Tube-bundle fins double-bridge structure provided by the utility model, the effect of air side flow-disturbing can be increased, there is higher heat exchange
Efficiency.
Brief description of the drawings
Fig. 1 is the schematic top plan view of fin；
Fig. 2 is the schematic diagram that pore homonymy opens bridge；
Fig. 3 is the schematic diagram that pore heteropleural opens bridge；
Fig. 4 is a kind of side view of power station air cooling heat-exchanging tube bundle fin double-bridge structure；
Fig. 5 is that the adjacent fins with a kind of power station air cooling heat-exchanging tube bundle fin double-bridge structure strengthen flow-disturbing effect schematic diagram.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The utility model is a kind of power station air cooling heat-exchanging tube bundle fin double-bridge structure, as shown in figure 1, there is perforate 3 on fin 1
With bridge opening 2.As depicted in figs. 1 and 2, fin reference plane 4 is the plane where 1 unprocessed region of fin, and homonymy opens bridge and is
Bridge opening 2 is located at the homonymy of fin reference plane 4 with perforate 3.As shown in figures 1 and 3, it is that bridge opening 2 is located at perforate 3 that heteropleural, which opens bridge,
The not homonymy of fin reference plane 4.
As Figure 1-Figure 4, fin 1 is provided with fin reference plane 4, and adjacent bridge opening 2 is located at fin base respectively on fin 1
The both sides in quasi- face 4.
As shown in figure 5, the first fin bridge opening 2-1 and the second fin bridge opening 2-2 are respectively equipped with two adjacent fins, i.e.,
Adjacent fins 1 with double-bridge structure of the present utility model, the flow-disturbing for strengthening gas side by bridge opening 2 staggeredly act on.
Fin of the present utility model in air side there is higher flow-disturbing to act on, thus heat exchange efficiency is higher.
