Abstract
The utility model discloses a compound middle-fin efficient corrosion-resistant heat exchange tube, which consists of a parent tube, a compound layer and fins and is characterized in that the outer side of the parent tube (1) is provided with a compound layer (2); the parent tube is a steel tube; the compound layer is made of aluminum and an aluminum alloy; the thickness of the compound layer (2) is 0.3-1 millimeter; the compound layer is provided with the middle fins (3); and the heights of the middle fins are 1.5-10 millimeters. The compound middle-fin efficient corrosion-resistant heat exchange tube is further characterized in that the middle fins on the compound layer of the compound middle-fin efficient corrosion-resistant heat exchange tube can bend towards one side to be manufactured into bent middle fins. The compound middle-fin efficient corrosion-resistant heat exchange tube is mainly applied to heat exchangers, air coolers and particularly evaporative air coolers.
Description
Technical field
The utility model relates to a kind of industries such as oil, chemical industry, metallurgy, electric power that are applied to, and finishes the heat exchange element of medium heat exchange, specifically the efficient corrosion resistant heat exchanger tube of a kind of compound middle wing.
Background technology
At present, known heat exchanger, the employed heat exchange element heat exchanger tube of air cooler major part are that light pipe or light pipe are processed into screwed pipe, and the screwed pipe wing height of general light pipe processing is all below 1.2mm, and is lower, claim again low finned tube, its corrosion resistance and high efficiency are not high.And the finned tube of employing bimetallic composite manufacturing, the wing height all more than 10mm, claims again high finned tube, is restricted in the use.
The utility model content
Technical problem to be solved in the utility model is: be to provide a kind of structure simpler, heat transfer efficiency is higher, and unit heat exchange area is large, corrosion resistant heat exchange element.
The utility model solves the problems of the technologies described above the technical scheme that adopts: provide a kind of compound middle wing efficient corrosion resistant heat exchanger tube, formed by parent tube, composite bed, fin, there is one deck composite bed in the parent tube outside that is characterised in that of the present utility model, parent tube is steel pipe, composite bed adopts aluminium, aluminium alloy to make, the thickness of composite bed has middle fin at composite bed between 0.3mm~1mm, the height of middle fin is 1.5mm~10mm.Feature of the present utility model is that also the middle fin on the efficient corrosion resistant heat exchanger tube of a kind of compound middle wing composite bed can to curving, manufacture crooked middle fin.
Operation principle of the present utility model is: processing medium is in heat exchanger tube, outer flowing, when flowing through the heat exchanger tube outer wall, because the heat exchanger tube outer wall has through cold-drawn or the compound aluminium of rolling depression method, the aluminum alloy corrosion resistant layer, composite bed tightly is fitted on the parent tube, make the outside can not be subjected to dielectric corrosion, parent tube is without corrosion resistant metal, save cost, owing on the composite bed alto middle fin being arranged, improved heat exchange efficiency, fin height is more suitable for being placed in shell-and-tube heat exchanger simultaneously, evaporation air cooler used the occasion of light pipe heat exchange originally, composite bed and on middle fin adopt aluminium, aluminium alloy has corrosion-resistant, the advantages such as easy processing.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing:
Fig. 1 is the schematic diagram in the efficient corrosion resistant heat exchanger tube of a kind of compound middle wing of the utility model cross section;
Fig. 2 is the schematic cross-section of another embodiment of the efficient corrosion resistant heat exchanger tube of a kind of compound middle wing of the utility model;
Specific embodiments
Embodiment 1: composite bed 2 thickness among Fig. 1 are 0.8mm, tightly are fitted on the parent tube 1, and the height of middle fin 3 is 5mm.
Embodiment 2: composite bed 2 thickness among Fig. 1 are 0.3mm, tightly are fitted on the parent tube 1, and the height of middle fin 3 is 1.5mm.
Embodiment 3: composite bed 2 thickness among Fig. 1 are 1mm, tightly are fitted on the parent tube 1, and the height of middle fin 3 is 3mm.
Embodiment 4: composite bed 2 thickness among Fig. 1 are 0.6mm, tightly are fitted on the parent tube 1, and the height of middle fin 3 is 10mm.
Embodiment 5: composite bed 5 thickness among Fig. 2 are 0.4mm, tightly are fitted on the parent tube 4, and the height of middle fin 6 is 4mm, and the middle fin 6 on the composite bed 5 can to curving, manufacture crooked middle fin 6.
The utility model is simple, and is advanced, reliable, and parent tube can adopt carbon steel and stainless steel to make, and multiple layer and middle fin can adopt aluminium, aluminium alloy manufacturing, corrosion-resistant, heat exchange efficiency is high, can be applied in heat exchanger, air cooler particularly on the evaporation air cooler.
