Abstract
The utility model discloses an anti-corrosion white copper and red copper composite high-tooth finned pipe which is composed of a seamless white copper liner pipe and a seamless red copper main pipe. After the seamless white copper liner pipe and the seamless red copper main pipe are compounded, the high-tooth finned pipe on a rolling forming spiral winding pipe body of the seamless red copper main pipe and the seamless main pipe are in an integrated structure. The anti-corrosion white copper and red copper composite high-tooth finned pipe is applied to the fields such as electric power, shipping, chemical engineering and oceanographic engineering.
Description
Technical field
The utility model relates to a kind of compound high finned tube, especially relates to the compound fins of high teeth pipe of a kind of anticorrosive copper-nickel alloy red copper.
Background technology
Along with developing rapidly of science and technology, to efficient, energy saving direction development, this also just requires the heat exchanger copper pipe with heat exchanger for chemical industry, ocean engineering, shipping industry, has that heat transfer is fast, high-effect, characteristics such as environmental protection, energy-conservation, high accuracy.Heat exchanger copper pipe on the domestic market mostly adopts the metal pipes such as simple copper, aluminium, copper alloy and fine copper finned tube as heat conducting material, and the shortcoming of above-mentioned this heat-exchange tube is that heat exchange efficiency is low, and resistance to corrosion is poor.
Copper-nickel alloy has the ability of the moving seawater corrosion of anti-current, red copper (fine copper) has excellent heat conductivity, to be copper-nickel alloy and copper tube reroll after compound the compound high finned tube of copper-nickel alloy red copper makes fin, according to the outstanding resistance to corrosion of copper-nickel alloy and the heat conductivity of red copper excellence, product have in conjunction with closely, little, the good heat-transfer of thermal resistance, intensity is high, flow losses are little, antiseptic property is strong, the advantages such as not yielding under long-term cold and hot operating mode, long working life.
Make heat exchanger pipe with the compound fins of high teeth pipe of copper-nickel alloy red copper, according to the heat conductivity of copper excellence and the ability of the moving seawater corrosion of copper-nickel alloy anti-current, simultaneously by the efficient heat-exchange capacity of high finned tube, thereby reached anticorrosive, efficient, energy-conservation, safe purpose.
Summary of the invention
The purpose of this utility model is to provide the more rational anticorrosive copper-nickel alloy red copper of a kind of application compound fins of high teeth pipe for the problem that heat exchange is low with the tubing heat exchange efficiency, resistance to corrosion is poor.
In order to achieve the above object, the utility model is mainly realized by the following technical solutions.The utility model mainly is comprised of seamless copper-nickel alloy bushing pipe (interior) and the female pipe of red copper (outward), the female pipe of copper-nickel alloy bushing pipe and red copper is after compound, carry out again the fin machining moulding, namely the periphery at the female pipe of seamless red copper forms the fins of high teeth that helical form is twined body, and fins of high teeth and seamless female pipe are structure as a whole.
The utility model compared with prior art, have following obvious advantage and innovation: it is material that (1) bushing pipe adopts the copper-nickel alloy alloy, copper-nickel alloy is the acid bronze alloy take nickel as main adding elements, has that intensity is high, corrosion resisting property is strong, hardness is high, resistance and pyroelectricity be good.(2) the utility model adopts three-high mill to revolve to roll one-shot forming, and fin height is high, and density is large, and wing is apart from little, and fin is thin, the characteristics such as that product has is efficient, energy-conservation, anti-seawater corrosion.(3) the utility model product has in conjunction with tight, the advantages such as thermal resistance is little, good heat-transfer, intensity is high, flow losses are little.(4) the utility model product has anti-marine stream corrosive power.(5) product heat transfer coefficient of the present utility model is 2.5-3.5 times of light pipe, compares with other low finned tube heat exchanger with volume equipment, and exchange capability of heat can improve more than 25%.
The utility model is applicable to the fields such as electric power, boats and ships, chemical industry, ocean engineering.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
