Abstract:Recent studies project that the rapid growth of digital society, the increasing power density of electronic components, the increasing power density of electronic components and the limitations of traditional IT cooling systems lead to major sustainability challenges in data centers. As a result, this study is focused on developing new advanced two-phase cooling solutions for data center applications and evaluates to what extent a 3D-printed surface microstructure dictates the performance of two-phase loop heat pipes with opposite replenishment and two-phase immersion cooling solutions. A new numerical model is developed for flat loop heat pipes and suggests that the development of a multi-material 3D-printed evaporator, including a high conductive copper wick/groove structure and a low conductive stainless steel casing material results in an impressive performance enhancement compared to conventional structures. Furthermore, a pool boiling test on additive manufactured microchannels and microchannels including a lattice structure was executed and shows a significant performance enhancement for selective laser melting stainless steel microchannels compared to rough copper plain surfaces. In brief, this study observes that additive-manufactured two-phase cooling systems appear to be a significant performance enhancement compared to actual two-phase cooling systems and could play a key role in achieving worldwide sustainability goals.
