Abstract
The utility model provides a straight and high-efficiency inner fins heat exchange tube with a plurality of holes. The heat exchange tube consists of an outer tube and an inner tube, wherein the outer tube is connected with the inner tube by brazing a plurality of quincuncial fins, and each fin is provided with a small hole; an air inlet end of the inner tube is blocked by a plug, 18-25 quincuncial straight fins which are made from the copper or the stainless steel are brazed between the inner tube and the outer tube, and the depths of the fins are 0.15-0.22mm; each fin is provided with the holes with phi 2-4mm, and the position of each hole is that one hole is arranged every 10mm along the lengthways direction; and the lengthways direction is the middle of each fin. Due to the function of the fins, the heat exchange area is greatly enlarged, the flow status of the process gas is improved, and the heat exchange efficiency is improved, so that the heat exchange tube has the characteristics of being small in volume, high in heat exchange efficiency, low in manufacture cost, and the like.
Description
Technical field
The utility model relates to the heat exchange element in a kind of heat-exchange apparatus, especially in a kind of air separation plant in required interstage cooler of various types of compact machine or the booster expansion machine aftercooler different temperatures medium carry out the main components and parts of the equipment of exchange heat, belong to the heat transmission equipment technical field.
Background technology
Cooler is a very important unit in the air-separating plant, particularly for various types of compact machine (comprising air compressor, oxygen compressor, nitrogen compressor etc.) or booster expansion machine, in order to guarantee the normal operation of compressor, must cool off the high-temperature gas after the compression and enter next stage compression, so, the cooling effect of heat exchanger directly influences the efficient and the service life of compressor, also can influence the normal operation of whole air separation unit.In all kinds of coolers, adopt light pipe as heat exchange element, be the most traditional, prevailing structural shape, be characterized in simple in structure, make easy to maintenancely, but efficient is low, physical dimension big, weight is heavier, manufacturing cost is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing product on structural design, and wing heat exchanger tube in to provide that a kind of volume is little, heat exchange efficiency is high, the perforate of low cost of manufacture is straight efficient.It is on the basis of existing cooler, through improving, the straight efficient interior wing heat exchanger tube of perforate is substituted traditional light pipe heat exchanger tube.
The purpose of this utility model is finished by following technical solution, and it mainly is made up of outer tube, interior pipe, links to each other by soldering plum blossom shape fin between described outer tube and the interior pipe, offers aperture on the described fin.
The pipe inlet end is blocked with plug in described, between outer tube and the interior pipe there is by plain fin 18-25 plum blossom shapes, that make with copper or stainless steel, fin thickness 0.15-0.22mm soldering.
All have the aperture of φ 2-4mm on described each fin, position of opening is: one of vertical every interval 10mm; It radially is the middle part of each fin.
When process gas entered heat exchanger tube, the heat of gas was delivered on the outer tube by fin, reached the purpose of carrying out exchange heat with pipe cooling water outward.Because the effect of fin is equivalent to entire cross section has been divided into 21 intervals, has not only increased heat exchange area greatly, has also improved the flow condition of process gas, has improved heat exchange efficiency; Simultaneously, owing to the existence of aperture on the fin, not only can increase the turbulivity of process gas, improve heat transfer coefficient, but also can link up contact between the different intervals, and reduce the additonal pressure loss that causes owing to assignment of traffic is uneven between the different intervals, reduced the gas flow resistance.
The utility model compared with prior art has following technique effect: the first has increased the heat exchange area of unit volume, has improved heat exchange efficiency; It two is the length that has shortened tube bank, thereby has reduced the volume and weight of entire equipment, has saved material consumption, has reduced manufacturing cost.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is that fin of the present utility model launches back perforate figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Fig. 1,2, the utility model mainly is made up of outer tube 1, interior pipe 2, links to each other by soldering plum blossom shape fin 3 between described outer tube 1 and the interior pipe 2, offers aperture 4 on the described fin 3.
All have the aperture of φ 2-4mm on described each fin 3, position of opening is: one of vertical every interval 10mm; It radially is the middle part of each fin.
Embodiment:
Shown in Figure 1, the utility model mainly includes outer tube 1, interior pipe 2 and quincunx fin 3 and forms outer tube 1 diameter phi 28*1.2, interior pipe 2 diameter phi 14*1, interior pipe 2 inlet ends are blocked with plug, middle fin 3 by 21 plum blossom shapes, fin 3 thickness 0.18mm are connected with inner and outer pipe with method for brazing.The material of inner and outer pipe and fin can adopt copper or stainless steel according to arts demand.When process gas entered heat exchanger tube, the heat of gas was delivered on the outer tube by fin, reached the purpose of carrying out exchange heat with pipe cooling water outward.Because the effect of fin is equivalent to entire cross section has been divided into 21 intervals, has not only increased heat exchange area greatly, has also improved the flow condition of process gas, has improved heat exchange efficiency.
Shown in Figure 2, on each fin, all have the aperture of φ 3, position of opening is: one of vertical every interval 10mm; It radially is the middle part of the high h of each wing.When process gas enters heat exchanger tube, because the existence of aperture on the fin, each aperture is equivalent to a turbulent flow generator, not only can increase the turbulivity of process gas, improve heat transfer coefficient, but also can link up contact between the different intervals, and reduce the additonal pressure loss that causes owing to assignment of traffic is uneven between the different intervals, reduced the gas flow resistance.
