The specific embodiment
The implementation step of the utility model manufacturing be plate through cold moudling, referring to the structure of Fig. 4, then two plates, 2,3 make-ups are formed the plate pipe, this plate tube cavity is the passage of hot fluid circulation.In order to strengthen uniformity that hot fluid distributes in the plate pipe, strengthen the heat transfer of hot fluid, to improve intensity, the rigidity of plate pipe simultaneously, utilize inner fin 5 that the plate tube cavity is divided into many unit; In order to reduce air thermal resistance, enhance heat, at plate pipe external welding moulding upper plate pipe fin 1, lower plate pipe fin 4.Adopt between inner fin 5 and the plate pipe and be welded to connect.
As shown in Figure 1, form single plate pipe fin by one group of inner fin 5, a pair of profiled sheeting pipe 2,3, two exclusive fins (upper and lower plate pipe fin) 1,4.Wherein 101 is hot fluid inlets, the 102nd, the hot fluid outlet.As shown in Figure 2, form fin plate pipe family by a plurality of single plate pipe fins.Upper plate pipe fin 1, lower plate pipe fin 4 are referred to as outer fin.Wherein 201 is air intakes, the 202nd, air outlet slit.
Plate tube section shape can be divided into rectangle, rhombus, oblateness, and the utility model legend is rhombus.
Heat-sinking capability for the outer fin of reinforcement plate pipe at first strikes out the fin plane ups and downs ripple struction (as shown in Figure 3), and makes concavo-convex ripple 6,7 lay respectively at the both sides on fin plane, is staggered ordered state.Secondly according to concrete needs fin is squeezed into straight line chute or curve chute.Because outer fin layout parallel to each other, thereby its flow direction at fin of air that is positioned between fin is always parallel with fin, like this, air is during along fin two side flow, flow resistance is very little, the concavo-convex ripple of fin surface helps forming eddy flow, and what simultaneously these concavo-convex ripples had also increased fin helps forming eddy flow.These concavo-convex ripples 6,7 have also increased the heat exchange area of fin simultaneously, thereby the heat-sinking capability of plate pipe fin air cooler is correspondingly improved.Concavo-convex ripple 6,7 has strengthened the rigidity of fin simultaneously, makes fin in use not yielding, has guaranteed heat dispersion.
Bow type, V-type or S type can be adopted in inside and outside fin cross section, and chute can adopt linear, shaped form and linear+shaped form.Inside and outside fin structure is the combination of above-mentioned cross section and chute.Shown in Fig. 5～8, the utility model is only listed four kinds of forms such as bow type opening straight line chute inner fin 5, V-type opening direct current groove inner fin 8, bow type opening curve chute inner fin 9, V-type opening curve chute inner fin 10.Wherein: straight line chute inner fin is used to handle gas phase not to be had phase change medium or requires the less occasion of resistance drop; Curve chute inner fin needing to be used for the occasion of augmentation of heat transfer; Straight line chute+curve chute inner fin is used for the gas-liquid phase transition occasion, and wherein the gas phase section adopts the straight line chute, and condensation segment adopts curve chute inner fin.
The material of inner fin 5, outer fin 1,4 can adopt aluminium and alloy, stainless steel, copper and alloy thereof, titanium and alloy thereof and sheet metal manufacturings such as nickel and nickel-base alloy thereof, the material of upper and lower moulding plate also can adopt steel aluminium composite material or other metallic composites except that can selecting sheet metal manufacturings such as carbon steel, aluminium and alloy thereof, stainless steel, copper and alloy thereof, titanium and alloy thereof and nickel and nickel-base alloy thereof for use.
The plate pipe can adopt the welding of welding manners such as Laser Welding, electric resistance welding, argon arc welding, adopts welding manner to be connected between inner fin 5 and the forming board pipe, and the employing welding manner is connected between forming board pipe and the outer fin 1,4.
But single plate pipe fin or plate pipe fin family horizontal positioned, vertical placement also can tilt to place.Be horizontal positioned as shown in figure 11, blower fan places its underpart, and hot fluid enters plate pipe fin from 101 1 sides, goes out from 102 1 effluents, and cold air 201 enters from the below, and 202 flow out from the top.
The utility model can be applicable in gas-gas that power station air cooling, petrochemical industry air cooling and other are cooling medium with the air, the solution-air heat exchange occasion.
