Abstract
The utility model relates to a bimetal finned heat pipe which is used for recovery of gas energy in the industries with corrosive gases or gases containing corrosive components. The bimetal finned heat pipe comprises a base pipe (1) made of stainless steel, stainless steel fins are welded on the outer side of one end of the base pipe (1), and aluminum fins are rolled on the outer side of the other end of the base pipe (1). In other words, the bimetal fins are used outside the same stainless steel base pipe (1), so that corrosion resistance and high-efficiency heat exchange are achieved. The stainless steel fins are quite high in corrosion resistance so that the service life of the bimetal finned heat pipe can be prolonged, and the aluminum fins have good heat transfer performance, so that heat exchange area and cost of the bimetal finned heat pipe can be reduced.
Description
Technical field
The utility model relates to a kind of metal fin heat pipe.The gas energy that gas or gas contains the industry of the composition that is corrosive that is used for being corrosive reclaims.
Background technology
Heat pipe is the otherwise effective technique that realizes gas-gas heat exchange.The middle low temperature exhaust gas (below 200 ℃) that chemical industry produces perhaps contains corrosive gas, for example: SO
2, SO
3, NH
3Deng, perhaps contain the dust that is corrosive in the gas, for example: sodium metasilicate, sodium carbonate, chlor-alkali etc., this gas have very strong corrosivity, so heat resistant material can only be used stainless steel, can not be with aluminium or carbon steel.
Aluminium or carbon steel have good heat exchange property as heat exchange tube material, because they are not corrosion-resistant, do not have the heat exchange of corrosive gas or liquid occasion so generally be used in, for example: air preheater, aerial cooler etc.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of not only antiseptic property well but also the high bimetallic fin heat pipe of heat exchange efficiency.
The purpose of the utility model is achieved in that a kind of bimetallic fin heat pipe, comprising: parent tube, and said parent tube adopts the stainless steel parent tube, and the outside of parent tube one end is with high-frequency welding manner soldering stainless steel fin, and the outside of the parent tube other end rolls out the aluminium fin.
The utility model uses stainless steel parent tube and stainless steel fin in the heat absorbing end of heat pipe, because this part of heat pipe contacts with the gas that is corrosive; Release end of heat at heat pipe adopts stainless steel parent tube and rolling aluminium fin, because this part of heat pipe contacts with non-corrosiveness gas.Utilize stainless steel parent tube and stainless steel fin to reclaim to be corrosive the energy of gas, be used for preheating non-corrosiveness gas to the heat of recovery through stainless steel parent tube and aluminum fin.
The beneficial effect of the utility model is:
The utility model bimetallic fin heat pipe is to use two kinds of metal fins at same stainless steel hot tube outer surface; The heat pipe heat absorbing end adopts the stainless steel fin to absorb the waste heat of the gas that is corrosive below 200 ℃; The heat pipe release end of heat adopts aluminum fin preheating non-corrosiveness gas; Increase the energy of non-corrosiveness gas, reduce system energy consumption.The stainless steel fin has good antiseptic property can prolong the life-span of product, and the aluminium fin has good heat transfer property, can reduce the heat exchange area of product, reduces product cost.Therefore the utility model bimetallic fin heat pipe has been realized the dual purpose of anticorrosion and high efficient heat exchanging, the energy recovery occasion of the gas that is used to be corrosive.

Reference numeral among the figure:
Parent tube 1
Stainless steel fin 2
Aluminum fin 3.
The specific embodiment
Referring to Fig. 1, Fig. 1 is the utility model bimetallic fin heat pipe general structure sketch map.Can find out that by Fig. 1 the utility model bimetallic fin heat pipe comprises: parent tube 1; Parent tube 1 adopts the stainless steel parent tube; The outside of parent tube 1 one ends is with high-frequency welding manner soldering stainless steel fin, and the other end of parent tube 1 outside rolls out the aluminium fin, promptly; Same stainless steel parent tube uses two kinds of metal fins outward, thereby reaches the dual purpose of anticorrosion and high efficient heat exchanging.
Claims (1)
