New concepts are required for high-performance minichannel evaporators with low mass and reduced size involved in the cooling of cylindrical or conical surfaces. The development of one-piece stainless-steel evaporators using flow boiling CO₂ for the cooling of conical copper test specimens heated by a foil heater element is presented. The specimens mimic a mobile cooling device used in high-energy and particle physics. The stainless-steel evaporators were manufactured with a state-of-the-art 3D stainless-steel printer via selective laser melting. The computer-aided design and the construction of this new type of evaporators are described. A dedicated two-phase accumulator controlled loop filled with liquid CO₂ was developed, it allowed for operating four parallel connected evaporators. Cooling efficiency and manufacture reproducibility were experimentally investigated by applying different thermal loads and refrigerant mass flows.
