Tube Bending
Tube bending is a crucial value-added step in the production of liquid coolers, where tubes made of copper, aluminum, or stainless steel are precisely bent to create complex cooling structures. Tube bending requires not only the right selection of materials but also advanced CNC bending machines and precise tools to achieve accurate and repeatable bends without tube collapse or wrinkling. The versatility of tube bending allows for the economical production of a wide variety of bending geometries.
Tube Bending Technology
Process Information
Tube bending is a process in which a straight tube is bent into a desired shape. This is usually done using a bending machine that bends the tube around a specific axis. The tube is heated to make it more flexible and facilitate bending. It is important to note that the tube bending process can vary depending on the material and diameter of the tube. It is advisable to consult a professional to ensure that the bending process is carried out correctly and achieves the desired results.

Differences in Tube Materials
Copper tubes are a popular material for use in liquid coolers not only because of their excellent thermal conductivity but also because of their good bending properties compared to other materials. Copper tubes are very flexible, allowing for the realization of complex radii and geometries without tending to crack or break. With the right tube bending machine, stainless steel tubes can also be bent without any problems. The choice of stainless steel tubes is usually dictated by the application, where stainless steel is the preferred or only possible choice. In terms of thermal performance, stainless steel tubes in liquid coolers are significantly less efficient than copper or aluminum tubes.
