High precision fin mother tube research
In allusion to the problems of the patent tube which is used to produce fin tube on the present market such as the bigger wall thickness deviation, the inequality of physical properties, researches on technology improvement are carried out to develop high precision excellent performance finned tube patent tube, therefore process finned tube products with higher quality.
Research on high performance heat transfer fin tube used at the falling film evaporator
The product is mainly used for the new falling film evaporator with central air conditioning technology. Heat transfer performance increases more than 15％ than the first generation of falling film evaporator tube, this can improve the efficiency of the central air conditioning unit, reduce the usage amount of refrigerant, reduce greenhouse gas emissions, and decrease energy consumption.
Studies on a new type of finned structure, especially for drainage evaporation after spray of R134a refrigerant on the surface of the pipe, result in that the evaporation heat transfer coefficient is enhanced through the experimental validation.
R&D on stainless steel fin tube with 3D structure
For the heat transfer of the current special corrosion industry, such as chemical, oil, power, refrigeration. The usage of stainless steel heat exchange fin tube with higher heat transfer coefficient and lower weight could resist the hostile environment and provide a kind of heat transfer tube with a strong ability to resist oxidation corrosion.
Research on the current mould material for making copper alloy fin tube, through the theory and practice experience; give the solution on reasonable processing technology and suitable processing mould for machining stainless steel class high efficient finned tube with 3D finned structure. |
