High flux tube heat exchanger is the most important high-efficiency heat exchanger at present，the core component of which is high flux tube. On the one hand, high flux tube can reduce the steam demand. On the other hand, it can improve the heat transfer capability. In the large heat transfer system, because of the need of small temperature differences, the number of reboiler needed is very big. The use of high flux tube can reduce 3/4 the amount of reboiler, and temperature difference ΔT asks for only 5 ℃. Using high flux tube to replace traditional bare tube can eliminate heat transfer bottlenecks, meet the needs of larger heat load, and significantly increase production. At the same time, under the condition of keep the design efficiency, can reduce the cost.

Sinter high flux tube is a new product combining metal powder sintered method and machining technology. It can improve the heat transfer coefficient of the inside and outside tubes, thus they can significantly improve overall heat transfer coefficient of heat transfer tubes.

1.Material and size of high flux tube

Material:nickel-copper alloy（C70600，B10), carbon steel（SA179,10#）, aluminum alloy, stainless steel and so on.

Size: OD 19、25、32mm,length 2000～14000 mm

Under normal condition, the middle of high flux tube is enhanced section. Both ends are smooth. It is easy to wear tubes and expansion joint. High flux tube can do OEM as customers’ need. Products are packaged with wooden boxes.

2.Applicable medium of high flux heat exchangers

Ethylene glycol, light olefin, refrigerant, liquid oxygen, liquid nitrogen etc..

3.Applications of high flux heat exchangers

High flux heat exchanger can be used in phase change equipment, such as carburetor, evaporator, reboiler and condenser etc.
