Depending on the result of a closer look at these parameters, we design a suitable shell-and-tube heat exchanger or, thanks to the cooperation within our corporate group, we refer you to our sister company XELSION heat transfer solutions.
Together with XELSION, we can also provide you with high-quality, customized plate heat exchangers within a short span of time. Learn more about XELSION.
Once a suitable technology has been selected for your project, the heat exchanger is to be dimensioned. Our engineering department determines the heat transfer area and the geometry of the heat exchanger according to the desired performance.
It is essential to achieve a complete calculation basis for the design of the heat exchanger. The transparent communication with customers and suppliers maintained at DELLER safety heat exchangers supports us in this endeavor.
The following parameters are required to fully design your heat exchanger:
- Input and output temperature Specific heat capacity
- Logarithmic temperature difference Heat exchange coefficient
- Heat exchange surface
- Reynolds number
- Prandtl number
- Nusselt number
Pressure drop calculation
Once the heat exchanger has been thermally designed, it is also important to determine the pressure drops in the apparatus. Pressure drops in a heat exchanger occur because the media used lose energy due to friction on the walls and flows in the flow channel, e.g. at the bends. The aim is to reduce this pressure drop with the aid of suitable dimensioning and geometry in order to further increase the efficiency of the heat exchanger and achieve a more uniform flow through the apparatus.
