Abstract
The utility model relates to a heat exchange device, in particular to a telescopic heat exchanger. The heat exchanger comprises a heat exchange tube which is composed of a double layer structure formed by suiting exchange tubes from inside to outside. The heat exchange device is characterized in that the two ends of an inner exchange tube are extended out of an outer exchange tube, and the two ends of the outer exchange tube are connected with the outer wall of the inner exchange tube in a sealing way; the two ends of the inner and the outer exchange tubes are respectively provided with connectors. The technical proposal of the utility model has the characteristics of reasonable structure, simple processing and making, high working efficiency, convenient maintenance, etc.
Description
Technical field
This new technology relates to a kind of heat-exchange device, particularly a kind of tube-in-tube heat exchanger.
Background technology
The compressed air purification industry is to rise gradually and develop industry faster in China in recent years, under the situation of global available resources growing tension, utilize compressed air as power source general be applied in all trades and professions.Because different industries is different to compressed-air actuated quality requirements, so the compressed air freezing type drier is widely used.
The regenerator of at present domestic compressed air freezing type drier, all adopt shell-and-tube heat exchanger, this kind heat exchanger exists many shortcomings when using in the little drying machine for the treatment of capacity: because treating capacity is little, selected caliber is very little, making tube sheet owing to the little and bad welding of area like this, disposable solder yield is lower.When the regenerator core was made, because area is little, the distance of tube and tube was short, the pipe that is not easy to rise, and the disposable pipe qualification rate that rises is low, and after freezing, because after expanding with heat and contract with cold, the pipe place of rising is very easy to leakage, so major part will be carried out the secondary pipe that rises, production efficiency is low.
Summary of the invention
The utility model mainly is at above defective, proposed a kind of rational in infrastructure, manufacture the tube-in-tube heat exchanger simple, that heat exchange efficiency is high.
For achieving the above object, the technical solution of the utility model is: a kind of tube-in-tube heat exchanger, comprise the heat-exchange tube of forming by the inside and outside bilayer exchange pipe that is nested, diplomatic replace tubes is stretched out at the two ends of exchange pipe in it is characterized in that, and diplomatic replace tubes two ends and the sealing of interior exchange pipe outer wall are connected, and are separately installed with connector at inside and outside exchange pipe two ends.
Above-mentioned double-deck exchange pipe is " U " shape.
Above-mentioned double-deck exchange pipe is made of side by side the double-deck exchange pipe of two or more " U " shape, and inside and outside exchange pipe two ends link to each other with connector by tube connector respectively.
Above-mentioned double-deck exchange pipe is to adopt the material of copper or good heat conductivity to make.
The technical solution of the utility model has following characteristics:
1, rational in infrastructure, processing and fabricating is simple.Owing to adopt double-layer sleeve structure, make that processing is simple more, compact conformation is attractive in appearance;
2, heat exchanger tube adopts copper pipe as material, and the phenomenon of having avoided carbon steel to get rusty has improved operating efficiency, and safeguards easily in the future;
3, because the thermal conductivity of copper is fine, can effectively improve the heat exchange effect, reach the effect of energy-saving consumption-reducing.
Description of drawings
Below in conjunction with accompanying drawing the technical solution of the utility model is further described.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is vertical views of the utility model accompanying drawing 1;
Accompanying drawing 3 is A-A cutaway views of the utility model accompanying drawing 1.
The specific embodiment
As shown in Figure 1, 2, 3, tube-in-tube heat exchanger is made up of interior exchange pipe 5 and diplomatic replace tubes 4 bilayer sleeve that forms that is nested, diplomatic replace tubes is stretched out at the two ends of interior exchange pipe, diplomacy replace tubes two ends and the sealing of interior exchange pipe outer wall are connected, make diplomatic replace tubes inwall and interior exchange pipe outer wall form airtight chamber, exchange pipe two ends are separately installed with connector 1 outside, are separately installed with connector 3 at interior exchange pipe two ends.Double-deck exchange pipe can be made into " one " font or " U " shape as required.According to the exchange area needs, the double-deck exchange of " U " shape pipe can be made up of the shown in Figure 2 two double-deck exchange pipes of " U " shape arranged side by side, two tube heads at diplomacy replace tubes two ends link to each other with connector 1 respectively, diplomacy replace tubes two ends are fixed with the tube connector 2 that is connected with diplomatic replace tubes respectively, and two tube connectors 2 at two ends are connected with connector 3.Connector is the pipe of end sealing.
Higher for the heat exchanger effectiveness that makes tube-in-tube heat exchanger, double-deck exchange pipe can adopt the material of copper or other good heat conductivity to make.
Claims (4)
1, a kind of tube-in-tube heat exchanger, comprise the heat-exchange tube of forming by the inside and outside bilayer exchange pipe that is nested, diplomatic replace tubes (4) is stretched out at the two ends of exchange pipe (5) in it is characterized in that, and diplomatic replace tubes two ends and the sealing of interior exchange pipe outer wall are connected, and are separately installed with connector at inside and outside exchange pipe two ends.
2,, it is characterized in that above-mentioned double-deck exchange pipe is " U " shape according to right 1 described tube-in-tube heat exchanger.
