Abstract
The invention discloses an efficient necking turbulence heat exchange pipe belonging to heat exchange elements, in particular a heat exchange pipe with an embossed middle surface and two necking ends. The efficient necking turbulence heat exchange pipe is especially suitable for a heat exchange pipe with small diameter. The efficient necking turbulence heat exchange pipe comprises a light pipe port area and an embossed heat exchange area. The efficient necking turbulence heat exchange pipe is characterized in that the light pipe port area is a necking area, and the outer diameter of the light pipe port area is 2-4mm smaller than that of the embossed heat exchange area. The invention has the advantages that by extruding a terminal of the heat exchange pipe into the necking area with the outer diameter 2-4mm smaller than that of the embossed heat exchange area, the distributed pipe quantity on a pipe plate with same area can be increased when the necking area with smaller outer diameter is connected with the pipe plate, the compact pipe distribution is realized, the heat exchange area is increased, and the distributed pipe quantity can be increased by 15-20 percent according to calculation and practice. Accordingly, compared with a heat exchanger using the same-diameter turbulence heat exchange pipe, the heat exchanger with same volume has the heat exchange efficiency improved by 10-15 percent, the investment is reduced by more than 20 percent, and the efficient necking turbulence heat exchange pipe is efficient heat exchange equipment for realizing energy saving and emission reduction.
Description
Technical field
The invention belongs to a kind of heat exchange element, particularly a kind of intermediate surface indent, the heat exchanger tube of reducing is adopted at two ends.
Background technology
The turbulent heat transfer pipe is a kind of high efficient heat exchanging element, and the turbulent heat transfer pipe is to be processed by a light pipe usually, and the turbulent heat transfer pipe comprises that two ends there are not the light pipe and the middle heat transfer zone that has embossing of processing.The diameter of two ends light pipe is identical with the diameter of embossing heat transfer zone, hereinafter to be referred as same footpath turbulent heat transfer pipe, the light pipe at turbulent heat transfer pipe two ends is welded on the tube sheet in heat exchanger, in order to guarantee the intensity of tube sheet, in national standard, the heat exchanging tube center distance has strict demand, and heat exchanger tube centre-to-centre spacing should be not less than 1.25 times heat exchanger tube external diameter, the heat exchanger tube external diameter is more little, and stringing quantity is many more.After heat exchanger tube external diameter and outer diameter of tube-sheet size were determined, the maximum stringing quantity of tube sheet affected the raising of heat exchanger heat exchange efficiency thus also along with determining.
Summary of the invention
Can't increase the deficiency of unit tube sheet area stringing quantity because of the port diameter reason in order to overcome existing turbulent heat transfer pipe, the invention provides a kind of efficient reducing turbulent heat transfer pipe, using this efficient reducing turbulent heat transfer pipe not only can use with footpath turbulent heat transfer pipe increases stringing quantity on the unit are tube sheet, and can meet request of national standard.
The technical solution adopted for the present invention to solve the technical problems is: a kind of efficient reducing turbulent heat transfer pipe, comprise plain end oral region, embossing heat transfer zone, and it is characterized in that: described plain end oral region is the external diameter little 2～4mm of its external diameter of reducing district than the embossing heat transfer zone.
Described reducing district is the extruding reducing.
Described embossing heat transfer zone has embossing for the light pipe surface.
Described embossing is the acutangulate rectangular vertical compression line of line or embossing center line and heat exchanger tube axis that baroclines of embossing center line and heat exchanger tube axis.
The invention has the beneficial effects as follows, be the reducing district of external diameter by termination extruding than the little 2～4mm of external diameter of embossing heat transfer zone with heat exchanger tube, the less reducing district of external diameter can make stringing quantity increase on the same area tube sheet when being connected with tube sheet, realized compact stringing, increased heat exchange area, it is calculated that and putting into practice to increase stringing quantity 15-20%.Embossed areas surface embossing has further increased heat exchange area, makes medium formation turbulent flow in the pipe, and embossing changes the outer media flow direction of pipe, further enhanced heat exchange simultaneously.Thereby the heat exchanger of the same volume of comparing with use footpath turbulent heat transfer pipe together can improve heat exchange efficiency 10-15%, reduces investment more than 20%, is the high-efficiency heat exchanger equipment of realization energy-saving and emission-reduction.
