What is three-dimensional ribbed tube?

A three-dimensional ribbed tube refers to a tubular structure with ribs or protrusions on its surface, extending along the length of the tube. These ribs can be evenly spaced or have a specific pattern, providing structural reinforcement or enhancing certain characteristics of the tube.

Three-dimensional ribbed tube applications

1. Heat Exchangers: Ribbed tubes are commonly used in heat exchangers to improve heat transfer efficiency. The ribs create turbulence in the fluid flow inside the tube, promoting better mixing and heat exchange between the fluid and the tube wall.

2. Structural Support: In some construction applications, ribbed tubes are employed to enhance the structural integrity of beams, columns, or other load-bearing elements. The ribs increase the surface area of the tube, improving its resistance to bending, buckling, or torsion.

3. Fluid Conveyance: Ribbed tubes can be used for fluid conveyance systems, such as pipes or hoses. The ribs inside the tube help to control the flow of fluids by reducing friction and preventing kinking or collapsing under pressure.

4. Aerospace Engineering: In aerospace applications, ribbed tubes can be utilized in the design of lightweight and strong structures. The ribs provide stiffness and strength to the tubes while minimizing their weight, making them suitable for applications like aircraft frames or rocket components.

5. Medical Devices: Ribbed tubes find application in medical devices and implants. They can be used as part of catheters, endoscopes, or prosthetic implants, where the ribs improve flexibility, trackability, or biocompatibility of the devices.

These are just a few examples of how three-dimensional ribbed tubes can be utilized in different industries. The specific design and characteristics of the ribbed tubes can vary depending on the intended application and desired properties.

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.

Three-dimensional ribbed tube advantages

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.
