The three-dimensional ribbed tube is a new type of enhanced heat exchange pipe fittings, and its heat exchange performance is better than that of all internally enhanced heat exchange pipe fittings at home and abroad. For the heat transfer in the air tube, the three-dimensional ribbed tube can reach up to 5.8 times the heat transfer of the bare tube under the same working conditions, and for the fluid with high Pr number, the enhanced heat transfer factor can reach a higher value. As far as the condensation heat transfer and boiling heat transfer in the tube are concerned, the heat transfer multiples are also 3 to 5 times and 2 to 5 times that of the same type of heat transfer in a bare tube under the same working conditions. Products are widely used in petrochemical, thermal power, light industry and various industries with heat exchange devices.
The three-dimensional ribbed tube has three-dimensional ribs, and has significant advantages such as good rib shape, high rib height, and variable rib density within the same tube. During the working process, turbulent flow will be generated, and the comprehensive heat exchange performance is unmatched by other enhanced heat exchange elements in the world.
The three-dimensional ribbed tube has a wide range of applications, strong variability, and can meet various environmental needs. Its processing technology has obtained national invention patents and won the gold medal of invention at the 39th Brussels World Expo. The products are used in many industries such as petrochemical, thermal power generation, air-conditioning device manufacturing and mechanical processing, and have achieved good results.
