Abstract
The utility model provides an oval H-type fin tube comprising an oval tube and fins arranged at the outside of the oval tube, wherein the fins are formed by two pieces of steel sheets which are provided with arcs matched with the outer diameter of the oval tube at the middle parts; and the two fins are symmetrically connected with the oval tube together. The oval H-type fin tube with the structure expands heating surface maximally, greatly reduces the wearing of steel tubes, has good heat conduction performance and good structural rigidity and can be applied in occasions with longer tube rows.
Description
(1) technical field
The utility model relates to heat exchange element, specifically a kind of heat exchanger tube.
(2) background technology
At present domestic heat exchanger components is numerous in variety, and performance difference is bigger, but fatal shortcoming is all arranged:
1, resistance is big, mainly is big with fluid front contacting section, equals the outer warp of steel pipe.At fluid through the very big resistance of out-of-date formation.
2, serious wear, when the flue gas that contains particle or air were flowed through steel pipe, particle can frontal impact, and press the caliber radian and pass through outer wall of steel pipe, makes the steel pipe serious wear.And lateral wearing is more serious behind the steel pipe, because fluid forms the vortex through behind the steel pipe, particle is shuttling movement herein, the accelerated wear test steel pipe.
3, because the steel pipe rear side has formed the vortex, the surface of steel pipe does not participate in heat exchange herein, so formed the heat exchange dead band.
(3) summary of the invention
The purpose of this utility model is to provide a kind of heating surface big, and the wearing and tearing of steel pipe are low, the oval H type extended surface tube that heat-conductive characteristic is good.
The purpose of this utility model is achieved in that
It comprises the fin that elliptical tube is outer with being arranged at elliptical tube, and described fin is to have the steel disc of the circular arc that matches with the external diameter of elliptical tube to constitute by two centres, and two fins link together with elliptical tube symmetrically.
The utility model can also comprise:
1, described elliptical tube comprises two, and described fin is that two centres have the steel disc of two circular arcs that match with the external diameter of elliptical tube to constitute, and two fins link together with two elliptical tubes symmetrically.
2, described fin is rectangular.
3, the described fin person of being semicircle.
Oval H type extended surface tube of the present utility model also claims oval H type gilled tube, and it is to have two centres the steel disc (rectangle or semi-circular) of circular arc to weld together with oval light pipe symmetrically.Front shape is quite as letter " H ", so be called oval H type extended surface tube.This kind structure has been expanded heating surface to greatest extent.And greatly reduce the wearing and tearing of steel pipe.H type extended surface tube adopts welding (electric resistance welding, flash welding, medium frequency welding, ratio-frequency welding, Laser Welding etc.) process, its welding back weld seam fusion rate height, and weld seam tensile strength is big, has good heat-conductive characteristic.The oval extended surface tube of H type also can manufacture the oval extended surface tube of " two H " type of bielliptic(al) pipe, and the good rigidly of its structure can be applied to the long occasion of the row of pipe.Version: citation form is " H " type and two " H " type.
The utility model has formed the desirable regeneration product of the best of heat exchanging piece.

(5) specific embodiment
For example the utility model is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1-Fig. 3, first kind of embodiment of the present utility model composition comprise elliptical tube 1 and be arranged at the outer fin of elliptical tube, described fin is to have the steel disc 2 of the circular arc that matches with the external diameter of elliptical tube to constitute by two centres, and two fins link together with elliptical tube symmetrically.Rectangular or the person's of the being semicircle of described fin.
In conjunction with Fig. 4-Fig. 6, second kind of embodiment of the present utility model is on the basis of this first kind of embodiment, described elliptical tube comprises two, is elliptical tube 3 and elliptical tube 4, described fin is that two centres have the steel disc 5 of two circular arcs that match with the external diameter of elliptical tube to constitute, and two fins link together with two elliptical tubes symmetrically.
Claims (4)
