Description
Technical field
The utility model relates to a kind of heat-exchange device, particularly a kind of single finned tubular radiator.
Background technology
The single finned tubular radiator that is applied to direct air cooling system is at present combined snakelike aluminium fin by special process with the parent tube surface compact, the aluminium fin brazed need not galvanizing by dipping on parent tube.Main feature is: the parent tube maximum gauge is bigger, and the steam flow area is big in the pipe, helps vapor-liquid separation and antifreeze, and less with the air side resistance in the pipe, flow behavior is good, selects for use power of fan and pipe outer air resistance and pressure drop that relation is arranged, and it is lower to clean hydraulic pressure.It is bigger that weak point is that integral body takes up room, and heat transfer property remains to be improved.The conductivity of heat of single finned tube is improved one's methods generally punching press or mold pressing fin, forms the turbulent flow lug, flow-disturbing hole, guiding gutter, ripple etc.But shortcoming is arranged mostly: improve seldom, increase the air side resistance as heat exchange property, reduce the fin quality, increase fan energy consumption, easily fouling or Tibetan dirt also increase the heat exchanger thermal resistance simultaneously, influence heat transfer property, to cleaning harmful effect are arranged also.
The utility model content
The purpose of this utility model provides a kind of single finned tubular radiator, and it has enhance heat transfer performance, can not increase air drag simultaneously.
Single finned tubular radiator of the present utility model, comprise parent tube and fin, described parent tube is the carbon sheet pancake pipe of aluminizing, and along the vertical equally spaced installation silico-aluminum wave-fin of two side planes of this flat parent tube, a plurality of triangular fovea fins are interspersed on the fin.
The wingization ratio of above-mentioned described fin is greater than 15.
Described fin is welded on the parent tube, integral seamless welding between fin and the parent tube.
Described parent tube adopts the aluminizing welded steel plate to form the inside and outside protective filmy layer that respectively is provided with.
Described fin is an aluminum, and along the snakelike cross direction profiles of parent tube, the triangle rib of vertical mold pressing majority on the fin, triangle rib are staggered concavo-convex on the fin both sides.
The distance on described triangular fovea fin and fin plane is 1mm to the maximum, and rib is long for about 13mm, and the angle on slant edge face and fin plane is between 15 °～30 °.
The layout of the concavo-convex rib of described two adjacent fins is corresponding consistent.
Owing to be provided with the flat parent tube and the wave-fin pipe in large tracts of land cross section, and the concavo-convex rib of triangle be set on finned tube, can effectively increase radiating effect, air flow resistance is kept basically not to be increased.Reached following effect: the local heat transfer coefficient height; Air drag amplification is little; Do not reduce the fin quality; Manufacturing process is simple; Influence such as scaling fouling is little, guarantees to clean.

The specific embodiment
As shown in Figure 1, single finned tubular radiator structural representation of the present utility model, the pancake parent tube 2 that whole whole finned tube is made by the carbon sheet of aluminizing, along the vertical equally spaced installation silico-aluminum wave-fin 1 of two side planes of flat parent tube 2, some triangular fovea fins 4 are interspersed on the fin 1.This high wing ratio of having optimized can reach more than 15, has improved the heat exchange property of pipe outer air side.Fin 1 is welded on the parent tube 2, be enough to the impact of firmly arriving high pressure resistant rinse water, and permanent deformation can not take place.Whole consistent seamlessness between assurance fin 1 and the parent tube 2 has reduced the thermal resistance between arriving outside the pipe in the pipe.The material of parent tube 2 adopts the aluminizing welded steel plate to form, the inside and outside protective filmy layer that respectively is coated with, not yielding and gas leakage in the installation and operation process.The section feature of parent tube 2 is heavy in section flat, and the cross section length-width ratio reaches more than 11 for well.The steam in this pipe and the contact area of tube wall are bigger, have increased heat dispersion, and bigger length-width ratio is arranged again, greatly reduce antifreeze requirement.
As shown in Figure 1 and Figure 2, fin 1 is an aluminum, snakelike cross direction profiles, each fin patrix extrudes some triangle ribs 4, and these triangle ribs 4 are staggered concavo-convex on fin 1 both sides, concavo-convex rib and fin plane are provided with by Fig. 2, Fig. 3, fin is based on plane 5, and mold pressing goes out lug, nib 6 and recessed rib 8, and the centre is slope 7, make concavo-convex rib lay respectively at the both sides on fin plane like this, be staggered wavy arrangement.This rib is vertical with the gas flow direction of fin both sides, and like this, gas is easy to generate eddy flow during along fin two side flow.Staggered concavo-convex rib sill make and the gas rotation make fin gas nearby and gas at a distance constantly exchange, and have also destroyed the boundary layer of gas flow simultaneously, have improved heat dispersion greatly.These concavo-convex ribs have also increased the area of dissipation of fin.Concavo-convex rib can significantly not increase loss of air pressur, can not influence the cleaning of heat exchanger yet.Concavo-convex rib has strengthened the fin rigidity, makes fin not yielding in installation and use, guarantees heat dispersion.These ribs are perpendicular to the fluid flow direction of fin both sides, concavo-convex staggered distribution.
As shown in Figure 4, the layout of the concavo-convex rib of two adjacent fins on the wave-fin, correspondence position is consistent, that is to say lug, nib 6 corresponding to lug, nib 6 ', so at concavo-convex rib, still the spacing of fin of several inclined-planes part all is to equate constant, concavo-convex rib only changes the direction that air flows, to flow velocity change little, air drag amplification is little.
The cross section length-width ratio that specifically is of a size of parent tube 2 is about 11, and the wing specific energy of finned tube reaches between the 18-20, and the distance on concavo-convex rib and fin plane is 1mm to the maximum, and rib is long to be 13mm, and the angle on inclined-plane and fin plane is between 15 °-30 °.
By concavo-convex rib and slope, change air-flow direction, increase turbulent flow, improved heat exchange property.Unified layout between fin, the inclined-plane of concavo-convex rib and fin plane included angle are little, and the spacing on concavo-convex rib and fin plane is much smaller than spacing of fin, and through optimizing, the resistance amplification of air side is little.The interlaced arrangement of concavo-convex rib does not only reduce the fin quality, and has increased the rigidity of fin, and is not yielding, beneficial to the transportation installation and operation of finned tube etc.Processing to fin needs only by the mould die forming simple and fast.Spacing of fin is constant in addition, and it is unobstructed to flow between the concavo-convex rib, does not have the dead angle of fouling, and cleans easily.
