Vipertex® enhanced surfaces, either in a tube or flat rolled configuration, can be used in a variety of applications. These engineered surfaces are rolled into coils of metal, promoting repeatability, volume production and cost efficiency.
Vipertex® makes it possible to incorporate enhanced surfaces into heat exchanger designs with greater flexibility and scalability, helping you optimize a solution for your project.
Heat exchangers using Vipertex® tubes and/or flat goods can be substantially more efficient than those produced with conventional materials. Various operating conditions need to be considered so that the appropriateness of Vipertex® can be determined and optional strategies can be considered before making final design decisions. An example of an optional strategy is the fact that the Vipertex® heat transfer efficiency curve is not linear. In the case of the Vipertex® 1EHT, the same heat transfer can be achieved at a much lower flow rate, which can inform optimization decisions about pumping power, size of the overall unit, footage and diameter of tubing required, etc. It may be helpful to read Evaluation of Heat Exchanger Designs Using Enhanced Heat Transfer Tubes, which was presented at the 2017 American Society of Thermal and Fluids Engineers (ASTFE) Conference and 4th International Workshop on Heat Transfer (IWHT).
The complexity of the real world installations uggests tha ta conversation take place early in the design process with the Vipertex® team to evaluate the applicability of Vipertex® tubing and flat sheets in a given design for a heat exchanger installation or manufactured product. More can be learned by reading Comparison of Heat Exchanger Designs Using Vipertex® 1EHT Enhanced Heat Transfer Tubes, presented at the 22nd International Congress of Chemical and Process Engineering CHISA 2016 and the 19th Conference on Process Integration, Modeling and Optimisation for Energy Saving and Pollution Reduction PRES 2016.
HTRI® members can take advantage of a calculation tool that plugs into HTRI® Xchanger Suite software to help them optimize single phase flow installations using Vipertex® tubing.
Operating Condition Parameters
While an early conversation with the Vipertex® team is clearly the best route, the following topics are covered in order to provide a degree of insight into the potential for Vipertex® in the context of various operating condition parameters.
