Description
Technical field
The present invention relates to finned tube field, be specifically related to the flat tooth finned tube of a kind of H type and finned tube heat-exchanging tube bundle thereof.
Background technology
H type finned tube, also claims H type extended surface tube or H type gilled tube, claims again video disc pipe, is that two centres are welded together to form to finned tube with light pipe symmetrically with the steel disc of circular arc, because of front shape picture letter " H ", therefore be called H type finned tube.H type finned tube generally adopts Flash Welding process, and after its welding, weld seam fusion rate is high, and weld seam tensile strength is large, has good heat-conductive characteristic.H type finned tube also can be made into two-tube double H-type finned tube, and the good rigidly of its structure can be applicable to the longer occasion of pipe row.
H type finned tube has good anti-dust stratification ability and abrasionproof performance, is widely used in containing in grey more heat exchange occasion, as the heating surface of coal-burning boiler coal economizer and all kinds of waste heat boilers.Serious for avoiding restraining dust stratification, the spacing of fin in H type finned tube is larger, and generally more than 20mm, thereby the wingization of H type finned tube is lower in actual applications.In existing H type finned tube, fin surface is continuous flat surface, the enhanced heat exchange benefit of finned tube mainly comes from the expansion heat exchange area that in finned tube, fin provides, and continuous strand straight fins does not have obvious invigoration effect to the convection transfer rate of fin surface.
Summary of the invention
The present invention carries out in order to address the above problem, and object is, by providing a kind of discontinuous form discontinuous heat exchange surface, further to improve the enhanced heat exchange effect of existing H type finned tube.
In order to achieve the above object, the present invention has adopted following technical scheme:
< structure one >
The invention provides the flat tooth finned tube of a kind of H type, there is such feature, comprise: base tube portion, in a tubular form, at least one foundation pipe, and fin portion, comprise and be multiplely axially connected to the flat tooth fins set of rectangle on the outer wall of base tube portion with preset space length along base tube portion respectively, wherein, the flat tooth fins set of rectangle comprises two flat tooth fins of rectangle that are positioned at least one foundation pipe both sides, in the flat tooth fin of rectangle, being recessed into certain radian is connected with the outer wall tabling of base tube, two flat tooth fins of rectangle form H shape mutually across a certain distance and with base tube, the every flat tooth fin of rectangle comprises the substrate being fixedly installed on outer wall, the multiple flat tooth being connected with substrate, and multiple open slots that are formed between every two adjacent flat teeth, multiple flat teeth are arranged on rectangular fin with in the base tube dual-side portion that air flow direction parallels outward.
In the flat tooth finned tube of H type provided by the invention, can also there is such feature: wherein, that base tube is shaped as is cylindrical, any one in ellipticity, flat tube shape.
In the flat tooth finned tube of H type provided by the invention, can also there is such feature: wherein, the flat tooth fins set of every two adjacent groups rectangle is parallel to each other.
In the flat tooth finned tube of H type provided by the invention, can also there is such feature: wherein, base tube has outer diameter D, the spacing L scope that two flat tooth fins of rectangle are separated by is: 0<L< outer diameter D.
