Abstract
The utility model discloses a steel-aluminum compound finned tube radiator. The utility model is characterized in that fins made of aluminum alloy are integrally molded on the outer side of the steel tube. The consumed steel, the gross weight and the consumed ammonia in the utility model are respectively one fifth, one fourth and one eighth of those used in the conventional steel tube radiator.
Description
Technical field
A kind of steel and aluminium alloy compound are cast the finned-tube evaporator that forms, and belong to the parts of refrigeration plant.
Background technology
Refrigeration system ammonia adopts steel pipe to make with cooling grid more at present, and advantage is a safety.But the coefficient of heat transfer K value in the outside differs greatly in the steel comb naked pipe, and the K value of the coefficient of heat transfer of steel pipe inwall and ammonia is at 2000W/K.M
2, the K value of the outside and air is at 7-8W/K.M
2The steel using amount of every KW is about 280 kilograms, consumed great deal of steel, increase the infrastructure cost of building simultaneously, the finned tube of aluminium alloy one casting forming, advantage is in light weight, the exchange capability of heat height, but the aluminum alloy corrosion resistant ability is leaked the loss that ammonia can cause personnel and property, prohibites use in some countries.
Summary of the invention
The utility model aluminium alloy compound pipe evaporator with both advantages together, both shortcomings are avoided, and adopt the outside of aluminum alloy fin pipe casing at steel pipe, forming inboard is the multiple tube evaporimeter of aluminum alloy fin pipe outside the steel pipe.
Effect of the present utility model is: saved a large amount of steel consumptions, the steel use amount is original 1/5th during same refrigerating capacity, and the weight of building structure is to use 1/4th of steel pipe, and in the pipe is 1/8th of former steel pipe with the ammonia amount.Aluminum alloy surface and air heat exchange K value are 1.3 times of steel pipe, refrigeration system has been saved the input of great deal of steel and building structure when mounted like this, and the minimizing of ammonia consumption improves the safety coefficient of system, even if there is accident to take place, the loss that causes will reduce than loss with the steel pipe system.
The utility model is realized at the outside of steel pipe integrally casting aluminum alloy fin.
Description of drawings
Fig. 1 is the sectional view of the multiple tube of two fins.
Fig. 2 is the sectional view of multi-disc finned tube.
1 is aluminum alloy fin, the 2nd among the figure, aluminium-alloy pipe, the 3rd, steel pipe.
The specific embodiment
The utility model aluminum alloy fin and pipe in manufacture process are cast in the steel pipe outside when being a high temperature, the coefficient of expansion of aluminium alloy is bigger much than steel, so aluminium alloy can tightly be enclosed within the outside of steel pipe behind the recovery normal temperature, the thermal resistance of these two kinds of metal surface contact heat-exchangings approaches zero, before the casting outer surface of steel tube is handled clean, aluminium and steel can form the embrittlement layer of layer of aluminum ferroalloy when casting, it welds together aluminium alloy and steel pipe, the thermal resistance of two faces really is zero, the length of aluminum alloy fin and thickness, according to the heat exchange amount of reality and the economic consumption decision of aluminium alloy, the quantity of outside fin by inside and outside heat exchange k value than and actual the use in structure determine, the single aluminum alloy fin multiple tube of making is contacted or and be linked to be cooling grid and be used for refrigeration system.
With the individual tubes of moulding, the different operating positions according in refrigeration system are combined as suitable form in addition, such as with the directly cooling evaporator of lowering the temperature in the freezer time, are combined into parallel connection and are installed in the freezer top.When making condenser, vertically many uses.Being used for air-cooler can many combination, and level by the blower fan forced circulation, is formed efficient air-cooler after installing.
When if compound steel pipe can not satisfy instructions for use, but the tubing of composite stainless steel pipe, copper pipe or other materials reaches actual application target.
Claims (3)
1. steel-aluminum composite fin tube evaporimeter is characterized in that the fin of aluminium alloy and pipe make at steel pipe outside integrally casting.
2. steel-aluminum composite fin tube evaporimeter according to claim 1 is characterized in that 1 to 90 of the quantity of fin.
3. steel-aluminum composite fin tube evaporimeter according to claim 1 is characterized in that the diameter 10mm to 350mm of steel pipe.
