Abstract
The invention discloses fins for a serial fin type heat exchanger. A fin body between pipe holes is provided with a first disturbance protrusion, thereby improving the rigidity of the fin body and playing a disturbance role in media which flow through the surface of the fin body, and turbulent heat transfer is arisen so as to ensure that the surface heat transfer coefficient of the fins is greatly improved. But at the same time, large numbers of medium vortex turbulent flow clusters are formed so as to increase the pressure loss when the media pass through a core body. The side face of the first disturbance protrusion is provided with a notch which is communicated with both sides of the fin body so as to ensure that partial media enter the other side of the fin body through the notch, thereby solving the technical problem of the vortex turbulent flow clusters and further improving the heat exchange efficiency of the fins.
Description
Technical field
The present invention relates to the heat exchanger technical field, relate in particular to a kind of fin of sheet string type heat exchanger.
Background technology
As shown in Figure 7 and Figure 8, the fin of existing sheet string type heat exchanger is to be provided with some pores on each fin, is provided with the pore flange in pore one side.Wherein, the shape of fin has a significant impact the heat exchange performance tool of heat exchanger.At present, generally the fin form of Cai Yonging has flat shape, and MEDIA FLOW is out-of-date to form laminar flow layer along fin surface, can not form the better turbulent layer of heat-transfer effect, and the surface coefficient of heat transfer of fin is lower, and heat exchange effect is relatively poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of fin of simple in structure, sheet string type heat exchanger that heat exchange efficiency significantly improves.
For solving the problems of the technologies described above, technical scheme of the present invention is: the fin of sheet string type heat exchanger, comprise fin body, described fin body is provided with the pore to fin body one side flanging, described fin body between the described pore is provided with the first disturbance projection, and the side of the described first disturbance projection is provided with the otch that is communicated with described fin body both sides.
As optimized technical scheme, the described first disturbance projection is towards the flange direction of pore, and the height of the described first disturbance projection is equal to or less than the height of pore flange.
As to improvement of the technical scheme, the described first disturbance projection is the bucking ladder shape
As to further improvement in the technical proposal, the periphery of described pore is provided with the second disturbance projection, and the side of the described second disturbance projection is provided with the otch that is communicated with described fin body both sides.
As to further improvement in the technical proposal, the described second disturbance projection is towards the flange direction of pore, and the height of the described second disturbance projection is equal to or less than the height of pore flange.
As to further improvement in the technical proposal, the described second disturbance projection is curved.
As to further improvement in the technical proposal, the edge of described fin body is provided with the corrugated bending.
Owing to adopted technique scheme, described fin body between the described pore is provided with the first disturbance projection, not only improved the rigidity of described fin body, and the medium on the described fin body surface of flowing through played the flow-disturbing effect, turbulent flow heat transfer has appearred, thereby the surface coefficient of heat transfer of fin is improved greatly, but formed a large amount of medium eddying turbulence groups simultaneously, increased the pressure loss when medium passes through core body; But the side of the described first disturbance projection is provided with the otch that is communicated with described fin body both sides, makes the part medium enter described fin body opposite side by otch, has then solved the technical barrier of eddying turbulence group, and the heat exchange efficiency of fin is further improved.

The specific embodiment
Embodiment one:
As shown in Figure 1, the fin of sheet string type heat exchanger, comprise fin body 1, described fin body is provided with the pore 2 to a side flanging of fin body 1, described fin body 1 between the described pore 2 is provided with the first disturbance projection 3, the side of the described first disturbance projection 3 is provided with the otch 31 of the both sides that are communicated with described fin body 1, in the present embodiment, each described first disturbance projection 3 has two otch 31, and otch 31 is separately positioned on the media flow direction, reduced the generation of eddying turbulence group.
As shown in Figure 3, the described first disturbance projection 3 is towards the flange direction of pore 2, and the height of the described first disturbance projection 3 further reduces the resistance that medium passes through less than the height of pore flange 21, thereby improves the heat exchange efficiency of fin.
As shown in Figure 4, the described first disturbance projection 3 is the bucking ladder shape, has improved the manufacturability of present embodiment and the rigidity of fin; As can be seen from Figure 2, the edge of described fin body 1 is provided with corrugated bending 4, makes the medium of turnover fin that turbulent flow take place, thereby as improving replenishing of heat exchange efficiency of fins.
Embodiment two:
Present embodiment and embodiment one are basic identical, and difference is: the periphery of described pore 2 is provided with the second disturbance projection 5, and the side of the described second disturbance projection 5 is provided with the otch 51 that is communicated with described fin body 1 both sides.
The described second disturbance projection 5 is towards the flange direction of pore 2, and the height of the described second disturbance projection 5 is less than the height of pore flange 21.
In the present embodiment, described second disturbance projection 5 is curved, around described pore 2 uniform settings.
Present embodiment has strengthened the intensity of pore on the one hand, prevents the damage of fin in fin serial connection technical process, has further strengthened the generation of medium turbulent flow simultaneously, and the heat exchange efficiency of fin is improved greatly.
More than only be for example to best mode for carrying out the invention for example, protection scope of the present invention is as the criterion with the content of claim, any equivalence techniques conversion of making based on technical clarification of the present invention all should be within protection scope of the present invention.
The present invention can be widely used in the technical field of heat exchangers such as the charge air cooler, oil cooler of engine, and the raising of heat exchange efficiency can significantly reduce the volume of heat exchanger, thereby has significantly reduced the use of material, has technique effect significantly.
