Abstract

The invention provides a composite finned tube. The composite finned tube is composed of an alloy heat exchange tube and fins. Materials of the alloy heat exchange tube are selected from steel, steel alloy, copper, copper alloy, aluminum, aluminum alloy, tin, tin alloy, rare earth aluminum alloy or nickel-chromium-iron alloy. Materials of the fins are selected from copper, aluminum, steel, copper alloy, aluminum alloy or steel alloy. The surface of the alloy heat exchange tube is coated with aqueous organic-inorganic hybrid super-hydrophilic coating, high-alkali-resistance hydrophilic coating, anticorrosion hydrophilic coating or surface ion exchange resin moisture absorption coating. The composite finned tube can meet all the requirements for performance of anticorrosion, wear resistance, low thermal contact resistance, high stability and dust deposition prevention.

Description

Composite fin tube
Technical field
The present invention relates to a kind of composite fin tube, belong to technical field of heat exchange.
Background technology
Finned tube is a kind of wall with ribbing, is widely used in the industry such as power, chemical industry, and many screw type heat-transfer surfaces or corrugated tubing are the most all considered as finned tube.It is to extension heat exchange area and promotes that turbulent flow has remarkable effect, and single-phase convection heat exchange or phase transformation heat convection are all had great role.The structure of finned tube exchanger is essentially identical with general shell-and-tube heat exchanger.Simply instead of light pipe as heat-transfer area with finned tube, due to heat transfer strengthen, compact conformation, therefore compact heat exchanger can be made；Finned tube exchanger is also commonly used for pipe outer gas is heated or cooled, and passes to steam or water in pipe, such as air cooler, boiler economizer, radiator etc..
The advantage of finned tube is mainly: 1) heat-transfer capability is strong: compared with light pipe, heat transfer area can increase 2～30 times, and heat transfer coefficient can improve 1～2 times；2) compact conformation: due to unit volume heat-transfer area strengthen, heat-transfer capability strengthen, under same thermic load compared with light pipe, finned tube exchanger pipe is few, barrel diameter or height can reduce, thus compact conformation and be easy to arrange；3) can more effectively and reasonably utilize material: not only due to compact conformation makes material usage reduce, and likely inlay for what heat transfer and technological requirement next flexible the selection of material, such as different materials were made or weld finned tube etc..
Finned tube as heat exchange element, long-term work in bad environments, High Temperature High Pressure or be in aggressive atmosphere, this requires that finned tube should have the highest performance indications, including: 1) anticorrosion (Anti-corrosion)；2) wear-resisting (Anti-wear)；3) low thermal contact resistance (lower contact resistance)；4) high stability (Higher Stability) 5) accumulatingdust.
Existing finned tube can not meet the most above-mentioned being required.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of composite fin tube.
The composite fin tube of the present invention, it is made up of alloy heat exchanger tube and fin, the material of described alloy heat exchanger tube is selected from steel and steel alloy, copper and copper alloy, aluminum and aluminium alloy, stannum and ashbury metal, rare earth aluminium alloy or nichrome, the material of described fin is selected from copper, aluminum, steel or their alloy, and described alloy heat exchanger tube surface scribbles the super hydrophilic coating of aqueous hybrid inorganic-organic, high alkali resistance hydrophilic coating, anti-corrosion hydrophilic coating or surface ion exchanger resin hygroscopic coatings.
Described fin machining process is as follows: on the basis of alloy heat exchanger tube, with welding gun, alloy fin is directly welded at alloy heat exchanger tube.
The composite fin tube of the present invention, it is possible to simultaneously meet anticorrosion, thermal contact resistance wear-resisting, low, high stability and the performance of accumulatingdust.
Detailed description of the invention
