Special Issue Information

Dear Colleagues,

Thermal management plays an important role in numerous energy-related systems and industrial applications, while water is widely used as the working medium for thermal management due to its relatively high thermal conductivity and low viscosity. In addition to single-phase convective heat transfer, water has also been utilized in phase-change processes, including boiling, evaporation and condensation, for efficient energy transport. Despite the massive efforts of academic researchers and industry, the underlying mechanisms of water-cooling processes, especially those involving phase change, remain to be elucidated due to the vast complexity of the heat transport and potential phase-transition processes. Additionally, the promotion and further enhancement of thermal management applications based on water are worth studying. This Special Issue plans to provide an overview of the most recent advances in water-related thermal management applications in diverse areas and their theoretical mechanisms.

The potential topics include but are not limited to:

  • Boiling/evaporation;
  • Condensation;
  • Heat pipes;
  • The thermal management of Li/ion batteries and electronics;
  • Nanoscale phase-change heat transfer;
  • Heat-transfer enhancement;
  • Theoretical analyses;
  • Multiscale modelling;
  • Multiphase flow.

Liquid thermal management is the prevailing method to maintain the operating performance and safety of Li-ion batteries. However, a better heat transfer performance is often accompanied by a higher power cost for liquid-based cooling methods. In the present work, V-shaped intersecting bypasses are integrated into conventional serpentine channels to reduce the liquid pressure drop across the cold plate without loss of thermal performance. The thermal-hydraulic characteristics of the battery thermal management system are studied based on CFD simulations. The non-dimensional j/f factor is developed and adopted to evaluate the heat transfer ability and friction loss of different designs. The effects of intersecting channel addition, flow direction, channel inlet, and outlet distributions are explored with the simulation results and data analysis. The results show that all of these factors would impact the thermal–hydraulic characteristics of the liquid cold plate. The addition of intersecting channels remarkably reduces the power cost, thus increasing the j/f factor. The alteration of the flow direction from longitudinal to widthwise could further improve the thermal-hydraulic characteristics of the intersected channel design. For conventional serpentine channels, the inlet and outlet distributions show no evident impact on thermal performance. However, regarding the intersected cases, the thermal-hydraulic performance is enhanced when the inlet and outlet are placed on the opposite sides of the cold plate, especially when the inlet velocity is less than 0.3 m/s. The findings of this study could shed light on the liquid flow channel design for battery thermal management. Full article

The manifold microchannel (MMC) heat sink is characterized by high heat transfer efficiency, high compactness, and low flow resistance. It can be an effective method for the high-flux removal of high-power electronic components. To further enhance the performance of the MMC, a double-layer pin–fin MMC structure was designed. The thermodynamic properties, including the flow and heat transfer characteristics, were numerically investigated using ANSYS Fluent with deionized water as the working liquid. Compared with the single-layer MMC, the temperature uniformity is better, the pressure drop is lower, and the comprehensive performance is improved at the cost of slightly larger thermal resistance for the double-layer MMC. The geometric effects on the thermodynamic performance were also analyzed. The results show that among the pin–fin structures with round, diamond-shaped, and rectangular cross-sections, the round pin–fins demonstrate the best comprehensive performance and the minimal thermal resistance. Under the same inlet velocity, the thermal resistance is decreased, and the comprehensive performance is first increased and then decreased as the pin–fin size increases. In addition, it is recommended to adopt a larger height ratio for low inlet velocity and a smaller height ratio for high inlet velocity. Full article
