The utility model discloses a foam metal tube-and-shell heat exchanger which adopts multilayer foam metal as an expanded heat transfer surface and aims to solve the problems of low heat transmission efficiency, large volume, high metal consumption and the like of the conventional shell-and-tube heat exchanger. By winding a plurality of layers of continuous ribbon foam metal core material outside each heat exchange pipe in a shell and filling a plurality of layers of continuous ribbon foam metal core material in each heat exchange pipe, the heat exchange performance inside and outside the pipes of the shell-and-tube heat exchanger is improved, the baffle plate of the traditional shell-and-tube heat exchanger is omitted, and the heat exchange area of the shell-and-tube heat exchanger is increased; and cold and hot fluids participating in heat transmission can flow through the foam metal passages of the foam metal core materials, so that the shell-and-tube heat exchanger achieves the effects of higher heat transmission efficiency, smaller volume and lower metal consumption under the premise of obtaining the same heat exchange effect.
Description
Technical field
The present invention relates to a kind of shell-and-tube heat exchanger that is widely used in industrial equipment, be specifically related to a kind of multilayer foam metal pipe shell type heat exchanger.
Background technology
Shell-and-tube heat exchanger is widely used in industrial circles such as chemical industry, oil, refrigeration, nuclear energy and power, and its consumption accounts for 70% of whole heat exchanger consumptions.Because global energy crisis, in order to cut down the consumption of energy, the demand of heat exchanging device is more and more in the industrial production, and the quality requirement of heat exchanging device is also more and more higher.In recent decades, development along with heat exchangers such as compact heat exchanger (board-like, plate-fin, pressure welding plate type heat exchanger etc.), heat-pipe heat exchanger, direct-contact heat exchangers, shell-and-tube heat exchanger is faced with challenge, in some occasion, shell-and-tube heat exchanger is replaced by some novel heat exchangers.But because shell-and-tube heat exchanger has the reliability and the adaptability widely of height, be that other high-performance heat exchanger is irreplaceable, its output still dominates so far.In order to improve the exchange capability of heat of shell-and-tube heat exchanger, intensifying method commonly used at present is to take to change supporting construction outside various forms of enhanced tubes of employing or the pipe to carry out, but has increased fluid flow resistance, has strengthened manufacturing cost.Therefore be badly in need of seeking a kind of more effective augmentation of heat transfer mode,, reduce heat exchanger volume, material usage and manufacturing cost to improve the heat transfer efficiency of shell-and-tube heat exchanger.
Foam metal (can reach 2000-10000m as the surface area in a kind of unit volume is very big
2/ m
3), the porous material of density little (being the 2%-25% of solid material), its application can provide a kind of new solution.Foam metal is made up of rigid backbone and inner hole, has the excellent physical property and the new material of good mechanical properties.It has very bigger serface and good trafficability performance, make fluid from foam metal by the time great heat exchange area arranged, and the metal material good heat-conducting makes temperature more can distribute equably, so foam metal is a kind of good augmentation of heat transfer material.The heat exchange area that foam metal can effectively increase heat exchanger tube is set inside and outside the shell-and-tube heat exchanger pipe, and enhanced tube is inside and outside to conduct heat.
Find through literature search prior art, realize the existing relevant patent of heat exchanger reinforcement with foam metal material at present, as application number is 200610104597.X, patent and application number that name is called " a kind of double-pipe metal foam heat exchanger " are 200810033289.1, name is called the patent of " inner lining with foam metal heat exchanger ", be primarily aimed at double pipe heat exchanger, and the connected mode of foam metal and heat exchanger tube all is by metal powder sintered, on the zone in plating or fusible pattern cast methods such as (seepage flow) cover between pipe internal surface and outer tube and the interior pipe, above-mentioned processing method processing request height, difficulty is big, and for shell-and-tube heat exchanger, the heat exchange pipe radical that needs is many, diameter is big, if employing said method, not only can expend a large amount of man-hours, influence the production cycle and the production cost height of product, influence applying in market.Learn according to market survey, the thickness of main foam metal product is subjected to the influence of production technology all in 1-10mm in the market, this drawbacks limit the application of foam metal in the major diameter heat exchanger tube, though also occurred the superthick foaming metal on the market, maximum ga(u)ge reaches 70mm, but superthick foaming metal not only cost is high, can not satisfy the needs of major diameter heat exchanger tube.
At shortcoming and the difficulty in the above-mentioned heat exchanger manufacture process, the invention provides a kind of multilayer foam metal pipe shell type heat exchanger, its foam metal material adopts serialization strip foaming metal material to roll and forms foamed metal core material, solved of the restriction of foam metal thickness, reduced manufacturing cost for its range of application.The multilayer foam metal core that is provided can roll according to the size of shell-and-tube heat exchanger housing and heat exchanger tube.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, a kind of multilayer foam metal pipe shell type heat exchanger is provided, make its interior by managing, as to manage outer filled and process metal mode, improve and manage interior, heat transfer outside a tube coefficient, expand heat transfer area significantly, solve the problem that the existing equipment heat exchange efficiency is low, volume is big, metal consumption is many.
The present invention is achieved through the following technical solutions, the present invention includes: heat exchanger shell, heat exchanger tube and foamed metal core material, foamed metal core material is filled in the heat exchanger tube outside and pipe inboard, and play a supporting role, saved the deflection plate of conventional tube shell heat exchanger, the hole that foamed metal core material inside has supplied gas or liquid medium to flow.
Described heat exchanger shell can be made by steel, titanium, aluminium, graphite, enamel or other materials.
The material of described heat exchanger tube can be metal material or nonmetallic materials such as graphite, engineering plastics such as steel, copper, aluminium.The shape of heat exchanger tube can be light pipe or enhanced tube, and enhanced tube can be other forms of enhanced tubes such as spiral fluted tube, transversally flute tube, cyclone pipe, bellows, spiral flat tube.The diameter range 5mm-76mm of pipe, thickness of pipe wall 0.2mm-6mm, many heat exchanger tube quadrate or the parallel distributions of equilateral triangle that specification is identical.
Described foamed metal core material adopts mature production technology, cheap serialization strip foaming metal material to make, base material material, nominal hole count and thickness according to the size Selection foam metal of the kind of heat transferring medium and heat exchanger tube, roll the serialization strip foaming metal core of the different numbers of plies, foam metal material is nickel foam, foam copper, foamed aluminium, foam stainless steel, nickel foam alloy, foam copper alloy or other metals, and the aperture is 0.05mm-6mm.
The present invention has significant advantage and positive effect.Because the uniqueness of foam metal structure, performance, this heat exchanger has greatly satisfied the heat transfer requirement, heat-transfer effect can obviously be better than existing shell-and-tube heat exchanger, thereby make whole shell-and-tube heat exchanger required heat exchanger tube quantum count under the condition that obtains identical heat exchange amount significantly reduce, thereby reduce the shell-and-tube heat exchanger volume and weight, save a large amount of metal materials, reduce the volume and weight of whole shell-and-tube heat exchanger, all can reduce 40-60% through primary Calculation shell-and-tube heat exchanger volume and materials.
