Abstract
The utility model relates to a rolling type high-thread heat exchange pipe made of composite materials, consisting of a base pipe and an outer pipe, wherein the base pipe is a stainless steel pipe; the outer pipe adopts an aluminium pipe and is rolled into a threaded fin shape; when in rolling, the outer pipe and the base pipe are pressed into a whole by extruding force so as to form tight attachment of the outer pipe and the base pipe; and when steam is introduced into the heat exchange pipe, the heat amount of the steam is transferred on the fin by an inner pipe, colder process gas outside the pipe is heated, so that the heat exchange purpose is achieved.
Description
Technical field
The utility model relates to the heat exchange element in a kind of heat-exchange apparatus, is the heat exchange element of the required steam heater of molecular sieve adsorption system in the air separation plant, belongs to the heat transmission equipment technical field.
Background technology
Steam heater is a very important unit in the air-separating plant, and the quality of stable, the quality of its performance directly has influence on the normal operation of molecular sieve system even whole air separation unit.In steam heater, in the past owing to be subjected to the restriction of equipment and process conditions, be enclosed within on the stainless parent tube after the general employing carbon steel material punching out fin, use hydraulic pressure steel ball method with parent tube and fin swelling then, this method technology more complicated, and fall behind, outmoded, can produce after the product completion that fin gets rusty, the not swelling and influence defective such as heat exchange effect of spacing of fin inequality, fin and parent tube part.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of existing product on structural design, and a kind of technology is simple, heat exchange efficiency is high, the high screw thread heat exchanger tube of the rolling formula of the composite of low cost of manufacture and provide.
The purpose of this utility model is finished by following technical solution, it is made up of parent tube and outer tube, described parent tube is a stainless steel tube, outer effective aluminum pipe is rolled into the fin shape of thread-shaped, and when rolling, described outer tube and parent tube are compacted into one with extruding force, form fitting tightly of outer tube and parent tube.
The fin pitch 2.5mm of described outer tube, spacing of fin 2.2mm, the thick 0.3mm of fin.
It is on the basis of original heat exchanger tube, through improving, the high screw thread heat exchanger tube of the rolling formula of composite is substituted punching out nest plate type structure in the past.When feeding steam in the heat exchanger tube, the heat of steam is delivered on the fin by interior pipe, with the outer colder process gas heating of pipe, reaches the purpose of exchange heat.
The utility model compared with prior art has following technique effect: the first has been eliminated the influence of gap thermal resistance, has improved heat exchange efficiency; It two is the uniformities that guaranteed spacing of fin, loses thereby overcome the additional drag of bringing owing to the uneven flowability that influence process gas of spacing of fin; It three is owing to adopted new material and new processing technology, has improved product quality, has reduced weight of equipment, has reduced manufacturing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model is made up of parent tube 1 and outer tube 2, described parent tube 1 is a stainless steel tube, outer tube 2 adopts aluminum pipe and is rolled into the fin shape of thread-shaped, described outer tube and parent tube are compacted into one with extruding force when rolling, form fitting tightly of outer tube 2 and parent tube 1.
Figure 1 shows that an embodiment of the present utility model, parent tube 1 diameter phi 25*2, material is a stainless steel tube, outer tube 2 materials are aluminum pipe, rolling back fin 3 external diameter 57mm, root footpath 26.6mm, fin pitch 2.5mm, spacing of fin 2.2mm, the thick 0.3mm of fin.
When feeding steam in the heat exchanger tube, the heat of steam is delivered on the fin 3 by parent tube 1, outer tube 2, with the outer colder process gas heating of pipe, reaches the purpose of exchange heat.
Because parent tube 1 and outer tube 2 are to utilize equipment when rolling that the extruding force of element is compressed, so parent tube 1 and outer tube 2 can be accomplished to fit tightly, and have the gap anything but, thereby do not have the gap thermal resistance, have improved heat exchange efficiency.Simultaneously, because screw-shaped fin 3 is to use the cutter roll forming, guaranteed the uniformity of spacing of fin, not only good looking appearance has also overcome the additional drag loss that brings owing to the uneven flowability that influences process gas of spacing of fin.
Claims (2)
