Hairpin heat exchangers design
As a registered HTRI member (© Heat Transfer Research, Inc.), at SACOME we have a new design tool, the Xhpe package, being this software suite a specific program for the calculation of hairpin heat exchangers. Thanks to this tool, our technicians are able to carry out an in-depth analysis of the heat transfer process that occurs in the U bundles of this type of heat exchangers, by getting a more optimized and reliable design.
HTRI integrates this calculation software in addition to the well-known modules of Xjpe for the design of double tube heat exchangers (tube-in-tube), and Xist for the design of multitubular heat exchangers (shell & tube), included in the version 7 of Xchanger Suite, thus endowing our technical department with the latest developments and advances in the field of heat transfer.
What is the configuration of a hairpin heat exchanger?
This design apparently consists of two shells that share a common U-shaped tube bundle. But, in fact, both shells make up a single volume since they are directly interconnected by a U-shaped header.
Unlike multi-pass heat exchangers (multiple passes in tubeside), hairpin heat exchangers have the peculiarity that the shellside stream circulates countercurrent to the tubeside flow, in all passes. This, together with a smaller shell section, makes it a more efficient and economical design compared to a multiple pass heat exchanger when the process requires a temperature crossing between the cold and hot fluid.

Differences between a continuous process and a batch process
All productive processes can be classified according to how the raw material input stage is carried out, and how the product is subsequently obtained. These processes are basically divided into continuous processes and batch processes, although we can find variations combining features from both processes.
Analysis of the thermal properties of fluids
The starting point in the design of any heat exchange system is the definition of how the thermal properties evolve throughout the process, whether heating or cooling.
