Abstract
The utility model provides a kind of efficient plate-fin heat exchanger fin, comprise dividing plate and be arranged on the unit fin on dividing plate, and described unit fin is evenly embarked on journey and in column is arranged on dividing plate, described unit fin is V-shape structure, and at least six cylindricality turbulent elements are evenly provided with on the V word outer surface of unit fin, the gross area of described turbulent element is 15%-20% of each unit fin area, the arrangement of the unit fin that every two rows are adjacent is identical, the adjacent unit fin of every two row is evenly staggered in arrangement, and staggered positions is the end of each unit fin.The utility model arranges turbulent element at fin surface, increases fin surface roughness, when fluid impact turbulent element, near turbulent element, forms whirlpool, and the less turbulence of aggravation fluid, destroys thermal boundary layer, further enhanced heat exchange.
Description
Technical field
The utility model relates to field of heat exchangers, particularly relates to a kind of efficient plate-fin heat exchanger fin.
Background technology
Plate-fin heat exchanger is because of its compact conformation, lightweight, and heat exchange efficiency advantages of higher is widely used in aviation field.In Aero-Engine Lubrication System, relate to the combustion lubricating oil larger to viscosity and carry out heat exchange, the heat exchange property of this just heat exchanger entirety proposes higher requirement.Patent of invention 201410229002.6 relates to a kind of corrugated offset strip fin, and this fin staggers, at half-wave length place opening at each unit wavelength degree place.Utility model patent 201420420804.2 discloses a kind of punching corrugated fin structure, and corrugated fin is offered some through holes, and above two kinds of methods can play growth-promoting turbulent flow to a certain extent, can increase the complexity of flowing, the effect of enhanced heat exchange.But for the combustion lubricating oil heat transfer process that viscosity is larger, the raising of its flow-disturbing effect and heat exchange efficiency is also not obvious.Therefore need to design the better plate-fin heat exchanger fin of a kind of heat exchange property for the heat exchange of aero-engine combustion lubricating oil.
Summary of the invention
The purpose of this utility model is to provide a kind of to firing the efficient plate-fin heat exchanger fin that lubricating oil flow-disturbing is effective, heat exchange efficiency is high.
The purpose of this utility model is achieved in that the unit fin comprising dividing plate and be arranged on dividing plate, and described unit fin is evenly embarked on journey and in column is arranged on dividing plate, described unit fin is V-shape structure, and at least six cylindricality turbulent elements are evenly provided with on the V word outer surface of unit fin, the gross area of described turbulent element is 15%-20% of each unit fin area, the arrangement of the unit fin that every two rows are adjacent is identical, the adjacent unit fin of every two row is evenly staggered in arrangement, and staggered positions is the end of each unit fin.
The utility model also comprises some architectural features like this:
1. the shape of cross section of cylindricality turbulent element described in is circular or triangle or square.
Compared with prior art, the beneficial effects of the utility model are: unit fin of the present utility model is V-shape, and V-shape fin is staggered can effectively enhance fluid disturbance.Arrange turbulent element at fin surface, increase fin surface roughness, when fluid impact turbulent element, near turbulent element, form whirlpool, the less turbulence of aggravation fluid, destroys thermal boundary layer, further enhanced heat exchange.In addition, turbulent element single-sided arrangement, in the outside of V-shape fin, makes fluid circulation good, less scaling in heat exchanger runner.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is perspective view of the present utility model;
Fig. 3 is the structural representation of fin unit of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Composition graphs 1 to Fig. 3, the unit fin 1 that the utility model comprises dividing plate 3 and is arranged on dividing plate 3, and described unit fin 1 is evenly embarked on journey and in column is arranged on dividing plate 3, described unit fin 1 is V-shape structure, and at least six cylindricality turbulent elements 2 are evenly provided with on the outer surface of unit fin 1, also namely the outer surface of every half unit fin arranges at least three turbulent elements 2, the gross area of described turbulent element 2 is 15%-20% of each unit fin 1 area, the arrangement of the unit fin 1 that every two rows are adjacent is identical, the adjacent unit fin 1 of every two row is evenly staggered in arrangement, and staggered positions is the end of each unit fin 1.The shape of cross section of described cylindricality turbulent element 2 is circular or triangle or square.
Each unit fin 1 fin of the utility model plate-fin heat exchanger is V-shape, and unit fin 2 angle is 120 ° ~ 150 °.
The utility model plate-fin heat exchanger fin, outside the V word of unit fin 1, turbulent element 2 is arranged in appropriate location, the sectional area of turbulent element 2 accounts for the unit fin gross area 15% ~ 20%, on each unit fin 1, the total quantity of turbulent element 2 is no less than 6, and shape is cylindricality, its cross section can be circle, triangle or square.This just can as required, change the size of unit fin 1, as long as ensure that the gross area of turbulent element 2 accounts for the gross area of unit fin than just passable.
As depicted in figs. 1 and 2: the utility model plate-fin heat exchanger fin is even stagger arrangement arrangement on each layer heat exchange dividing plate, and staggered positions is the length end of each unit fin 1.In Fig. 1, the direction of arrow is the direction of fluid flowing.
The connected mode of described turbulent element 2 and unit fin 1 is for welding.
N arranges fin and is placed between the upper lower clapboard of heat exchanger, and fin and upper lower clapboard are welded and fixed formation heat exchange aspect, and several heat exchange aspect forms a heat exchanger.
What accompanying drawing 3 provided is the case study on implementation that unit fin of the present utility model has 10 turbulent elements, is also every half-cell fin 1 has 5 turbulent elements.
Claims (2)
