The challenge focuses on designing an efficient small-scale heat exchanger to cool a Differential Scanning Calorimetry (DSC) instrument to temperatures as low as -150°C or even -180°C using Liquid Nitrogen in a gaseous state. The goal is to optimize heat exchange within the instrument's cold junction assembly, which currently uses an intracooler. Students are tasked with selecting materials and designing a compact, effective heat exchanger that ensures minimal heat loss while fitting existing mechanical connections, contributing to new cooling options for the instrument.

The development of an optimal small-scale heat exchanger would expand the cooling options for the DSC instrument, allowing it to reach ultra-low temperatures needed for advanced applications, increasing its value for customers.
