Abstract
The utility model relates to a lanced fin at tape alternation inclination, fin adopt the punching of panel beating cutter to form, and with the certain angle of every stagger arrangement unit slope of fin, stagger arrangement unit two rows adjacent is distinguished left and to the certain angle of right bank, is arranged at every stagger arrangement unit orientation formation S -shaped that is listed as. The advantage enhanced heat transfer that this structure is can the former lanced fin boundary layer initial section of make full use of thin, the thermal resistance is little, the fluids in the spiral flow that forms when the concave surface of fluid flow simultaneously and low reaches some areas break away from the phenomenon and also enable the intensified that conducts heat.
Description
Technical field
The utility model belongs to field of heat exchangers and in particular to a kind of serrated fin at tape alternation inclination angle.
Background technology
Plate-fin heat exchanger is a kind of compact, light and handy, heat-exchanger rig that high efficiency has certain voltage endurance capability again, has a wide range of applications in fields such as Aero-Space, chemical industry, refrigeration.Fin is the heat exchange core of fin heat exchanger core.Traditional serrated fin (referring to accompanying drawing 4) has obtained abundant certification through long-term theory and experimental study, and its foundation structure is effective enhanced heat exchange form, and the version being laminated ensure that the intensity of heat exchanger.But, at present for the requirement more and more higher of the heat transfer effect of the serrated fin of heat exchanger, need to find the fin structure on a kind of more effective heat-exchange method and enhanced heat exchange surface.
Utility model content
The purpose of this utility model is to provide a kind of serrated fin form at tape alternation inclination angle, and this structure is a kind of enhanced heat exchange device surface, has more effective heat exchange efficiency.
In view of the problems referred to above of prior art, according to disclosed in the utility model on one side, the utility model employs the following technical solutions:
A kind of serrated fin at tape alternation inclination angle, fin is formed using panel beating cutter punching, and each staggered unit of fin is tilted certain angle, and the staggered unit of adjacent two rows respectively to the left and the certain angle that is tilted to the right, forms the arrangement of s shape in each column staggered unit direction；When fluid is along the flow passage between each staggered unit, the feature augmentation of heat transfer thin using fin boundary layer the initial segment, thermal resistance is little, fluid flows through the helical flow being formed during the angle between two adjacent staggered unit of each column staggered unit and fluid break-off also being capable of augmentation of heat transfer simultaneously.
It is characterized in that, described angle of inclination is 15 degree.
Beneficial effect: this fin structure structure can make full use of the advantage augmentation of heat transfer that former serrated fin boundary layer the initial segment is thin, thermal resistance is little, fluid flows through the helical flow being formed during concave surface and the fluid break-off in downstream some areas also can make heat transfer be strengthened simultaneously.
This new construction can be widely applied to the fields such as Aero-Space, chemical industry, refrigeration, has a good application prospect and economic benefit.

Specific embodiment
With reference to embodiment, the utility model is described in further detail, but embodiment not limited to this of the present utility model.
Referring to accompanying drawing 1, a kind of serrated fin at tape alternation inclination angle of the present utility model, fin is formed using panel beating cutter punching, each staggered unit of fin is tilted certain angle, the staggered unit of adjacent two rows respectively to the left and be tilted to the right certain angle, forms the arrangement of s shape in each column staggered unit direction；Depending on fin thickness, spacing of fin, fin height, fin interruption distance and angle of inclination are passed through to calculate according to actual heat transfer requirements.
Referring to accompanying drawing 2 and 3, when fluid is along the flow passage between each staggered unit, the feature augmentation of heat transfer thin using fin boundary layer the initial segment, thermal resistance is little, fluid flows through the helical flow being formed during the angle between two adjacent staggered unit of each column staggered unit and fluid break-off also being capable of augmentation of heat transfer simultaneously.
In a kind of embodiment of the present utility model, the rake angle of the staggered unit of adjacent two rows is 15 degree, as shown in Figure 1.Through simulation calculation, the serrated fin of the such incline structure heat transfer factor under identical Reynolds number is 1.2～1.4 times of traditional serrated fin.
Claims (2)
1. a kind of serrated fin at tape alternation inclination angle, fin is formed using panel beating cutter punching, each staggered unit of fin is tilted certain angle, the staggered unit of adjacent two rows respectively to the left and the certain angle that is tilted to the right, forms the arrangement of s shape in each column staggered unit direction；When fluid is along the flow passage between each staggered unit, the feature augmentation of heat transfer thin using fin boundary layer the initial segment, thermal resistance is little, fluid flows through the helical flow being formed during the angle between two adjacent staggered unit of each column staggered unit and fluid break-off also being capable of augmentation of heat transfer simultaneously.
