Abstract
The utility model relates to a double-metal combined corrugated fin pipe, composed of a basal pipe and a sleeve pipe. The inner and the outer walls of the basal pipe are provided with regular convex-concave corrugation; the inner diameter of the sleeve pipe is provided with corresponding corrugation tightly matched with the corrugation of the outer diameter of the basal pipe; the outer diameter of the sleeve pipe is provided with regular radial fins respectively forming a helical shape. The utility model increases the contact tightness of the fins and the basal pipe, and the clearance heat resistance is reduced in maximum degree; the shock resistant ability is increased, the heat transfer coefficient is increased, the utilization area is decreased, the investment is saved, and the energy is saved.
Description
The utility model relates to a kind of high-performance heat transfer components-outer fin of diabatic process, interior corrugated fin pipe of being used for, and is applicable in the Air-cooled Heat Exchanger in the pipe, the outer occasion strengthened of all needing of pipe, the inside and outside occasion strengthened of needing of pipe in the air preheater.
At present, oil-refining chemical industry finned tube commonly used has winding-type, rolling type and wears four kinds of sheet type, solder types, and air cooler standard GB/T15386-94 has stipulated L, LL, KL, G, DR type.Its strengthening mechanism all is with the extension tube external surface area, reduces thermal contact resistance, and enhanced tube conducts heat outward, for the lower occasion of heat transfer coefficient in the pipe, does not then have good way.
External finned tube kind is a lot, has twenties kinds, but all is based on enhanced tube outward, and the problem in the pipe is often out in the cold.Though the heat transfer property in the oval finned tube pipe of developing in recent years has some improvement, DeGrain, the problem that thermal contact resistance is big is not resolved yet.
The purpose of this utility model is in order to overcome above-mentioned deficiency, and it is firm to provide a kind of fin to contact with parent tube, simultaneously in the enhanced tube, the outer composite corrugated finned tube of bimetallic of pipe.
The purpose of this utility model is achieved in that
The composite corrugated finned tube of a kind of bimetallic, form by parent tube and sleeve pipe, it is characterized in that: the inside and outside wall of parent tube is shaped on regular protruding, recessed ripple, and the inwall of sleeve pipe has the external diameter ripple of corresponding convex-concave ripple and parent tube closely to match, and the external diameter of sleeve pipe is shaped on regular radial fins.
The fin of described cover external diameter of pipe is shape in the shape of a spiral.
The material coupling of described parent tube-parent tube can be steel-aluminium, copper-aluminium, steel-copper.
The utility model has following actively useful effect:
After the utility model has adopted the composite corrugated structure of bimetallic, increase the tight ness rating that fin contacts with parent tube, reduced the gap thermal resistance to greatest extent, increase the ability of shock resistance, improve the permission serviceability temperature of finned tube, the ripple of parent tube inboard, the laminar region in the time of can destroying media flow in the pipe effectively, under the not high situation of flow velocity, can reach turbulent flow, improve the heat transfer coefficient in the pipe, reach the raising heat transfer coefficient, reduce usable floor area, reduce investment outlay, save the purpose of the energy.Compare with the DR type finned tube of same gauge material, heat transfer coefficient can improve more than 20% when cooling, allows serviceability temperature can improve 30 ℃.
Now in conjunction with the accompanying drawings:
Fig. 1 is a structural representation of the present utility model
Accompanying drawing number:
1. the inside and outside wall convex-concave of parent tube 101. parent tubes ripple
2. sleeve pipe 201. internal surface of sleeve pipe convex-concave ripples
202. sleeve outer wall fin
The composite corrugated finned tube of bimetallic of the present utility model, form by parent tube 1 and sleeve pipe 2, the inside and outside wall of parent tube 1 is shaped on regular protruding, recessed ripple 101, this protruding, recessed ripple is that helical form is seen Fig. 1, the internal diameter of described sleeve pipe 2 has the corresponding convex-concave ripple 201 and the external diameter ripple 101 of parent tube 1 closely to match, and the external diameter of sleeve pipe is shaped on regular fin radially 202.
During enforcement, the fin 202 of described cover external diameter of pipe is shape in the shape of a spiral.
During enforcement, the material of described parent tube 1-sleeve pipe 2 coupling can be steel-aluminium, copper-aluminium, steel-copper.
Claims (3)
1. composite corrugated finned tube of bimetallic, form by parent tube and sleeve pipe, it is characterized in that: the inside and outside wall of parent tube is shaped on regular protruding, recessed ripple, and the internal diameter of sleeve pipe has the external diameter ripple of corresponding convex-concave ripple and parent tube closely to match, and the external diameter of sleeve pipe is shaped on regular radial fins.
2. composite corrugated finned tube as claimed in claim 1 is characterized in that: the fin of described cover external diameter of pipe is shape in the shape of a spiral.
