| Abstract Scope |
A C-shaped oscillating heat pipe (OHP) was fabricated using laser powder bed fusion (L-PBF) and its design and subsequent testing are discussed. The fabricated OHP integrates a continuous-loop mini-channel, forming a compact thermal pathway with ultra-high thermal conductivity once it is filled with a working fluid. An integrated de-powder management strategy was incorporated into the design to enable effective powder removal from internal channels. A water block was also integrated above the OHP structure to function as a heat sink for enhanced thermal management. A prototype was fabricated to evaluate internal channel formation, de-powdering effectiveness, and overall structural fidelity through visual inspection and basic operational verification. Results demonstrate that L-PBF can successfully produce intricate OHP mini-structures with embedded thermal management components. While dimensional and performance optimization are ongoing, the fabricated prototype confirms the feasibility of manufacturing complex passive cooling devices with integrated de-powdering and heat sinking features using L-PBF. |
