Abstract
The invention discloses an elliptical heat exchange finned tube. The elliptical heat exchange finned tube comprises an elliptical composite heat exchange tube and aluminum fins welded on the elliptical composite heat exchange tube by adopting aluminum solder, and is characterized in that the elliptical composite heat exchange tube comprises a base tube and an aluminum or aluminum-silicon alloy layer which is densely covered on the surface of the base tube, wherein the base tube is a carbon steel tube or a stainless steel tube, and the radial section of the base tube is elliptical; and the aluminum fins are welded on the aluminum or aluminum-silicon alloy layer by adopting the aluminum solder. The elliptical heat exchange finned tube has the beneficial effects that the welding problem between the base tube and the fins in the elliptical heat exchange finned tube in which the base tube is a steel tube is solved.
Description
Technical field
The present invention relates to the cooler field, specifically, specially refer to a kind of ellipse heat-exchange finned tube.
Background technology
Cooler (heater) is a class of heat transmission equipment, is used as the cooling of gas in technological process or liquid and heating.In order to improve heat transfer effect, fin is installed in employing additional on heat exchanger tube usually increases heat exchange area, improves heat exchange efficiency.But because heat exchanger tube need have certain intensity, with carbon steel pipe or stainless steel tube be used as parent tube be purposes the most widely.Separately make because fin generally adopts aluminum or aluminum alloy, between itself and carbon steel pipe or stainless steel tube, welding is the difficult problem of the puzzlement industry always.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ellipse fin heat exchange pipe for the existing existing problem of heat exchanger tube of cooler.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of ellipse heat-exchange finned tube, comprise the ellipse composite heat exchange tube and and adopt the cored solder of aluminium to be welded on aluminium fin on the ellipse composite heat exchange tube, it is characterized in that, described ellipse composite heat exchange tube comprises that parent tube and densification cover the lip-deep aluminium of described parent tube or alusil alloy layer, parent tube is carbon steel pipe or stainless steel tube, its radial section is elliptical shape, and described aluminium fin adopts the cored solder of aluminium to be welded on aluminium or alusil alloy layer.
In a preferred embodiment of the invention, the major diameter of described ellipse composite heat exchange tube and minor axis diameter ratio are 1.8～4:1.
In a preferred embodiment of the invention, described aluminium fin adopts the cored solder interval of aluminium to be welded on aluminium or alusil alloy layer.
In a preferred embodiment of the invention, the main body of described aluminum alloy fin is rectangle, and the centre position of rectangle is preset with the elliptical aperture that matches with described ellipse composite heat exchange tube outer peripheral face.
Beneficial effect of the present invention is: solved parent tube and be the Welding Problems between parent tube and fin in the ellipse heat-exchange finned tube of steel pipe.
Description of drawings
Fig. 1 is the structural representation of a kind of ellipse heat-exchange finned tube of the present invention.
Fig. 2 is the cross-sectional view of a kind of ellipse heat-exchange finned tube of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
As depicted in figs. 1 and 2, a kind of ellipse heat-exchange finned tube that provides in figure comprise ellipse composite heat exchange tube 100 and and adopt the cored solder of aluminium to be welded on aluminium fin 130 on ellipse composite heat exchange tube 100, its ellipse composite heat exchange tube 100 comprises that parent tube 110 and densification cover the lip-deep aluminium of parent tube 110 or alusil alloy layer 120, parent tube 110 is carbon steel pipe or stainless steel tube, its radial section is elliptical shape, and aluminium fin 130 adopts the cored solder interval of aluminium to be welded on aluminium or alusil alloy layer 120.
The major diameter of ellipse composite heat exchange tube 100 and minor axis diameter ratio are 1.8～4:1.Through a large amount of experimental results show that, major axis is in this interval with the ratio of minor axis and in the situation that heat exchange area is identical, the pipe external resistance that ellipse composite heat exchange tube 100 is subject to is less than common pipe, can farthest bring into play the cooling effectiveness of elliptical tube, and it is best that operating efficiency can reach.
The main body of aluminum alloy fin 130 is rectangle, and the centre position of rectangle is preset with the elliptical aperture 131 that the outer peripheral face with the aluminium of ellipse composite heat exchange tube 100 or alusil alloy layer 120 matches, and four corners of main body have breach 132.
Beneficial effect of the present invention is: solved parent tube and be the Welding Problems between parent tube and fin in the ellipse heat-exchange finned tube of steel pipe.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
