There is a need in thermo-fluidic disciplines to measure temperature distributions in flowing liquids, for example to investigate heat transfer for performance improvement of devices. Although primarily used for medical applications, MR thermometry (MRT) has the potential to provide these measurements. This work applied MRT to investigate temperature distributions in a heat exchanger using different flow rates, demonstrating that MRT can provide high-quality 3D measurements of temperature fields in such setups. Collaboration with thermo-fluidic engineers can also benefit the medical community, for example through the investigation into MR compatible materials that could be used in medical devices.
