Summary

Low-temperature technology usually entails large temperature differences, meaning that refrigerants subject to a phase change (liquid/vapour) within the relevant temperature range cannot be used. Cryogenic fluids offer a suitable alternative, but achieving precise temperature control over a broad range remains challenging. For the temperature regulation of a vacuum test chamber, a temperature control unit (TCU) was developed to achieve a temperature range from -180 °C to +150 °C. Computational fluid dynamics (CFD) simulations were used to design pillow-plated heat exchangers (thermal shrouds) that enable optimal fluid distribution along the flow path. This ensures high temperature homogeneity across the surface while minimizing pressure losses. With an overall area of 150 m², the thermal shrouds can handle a cooling capacity of up to 40 kW. This work focuses on the design of the thermal shrouds, guided by CFD simulation results.
