Summary

Against the backdrop of global energy shortages and the dual-carbon policy, new energy, renewable energy, and energy storage have received increasing attention in practical applications and research and development. For these new energy systems, the key research direction is to ensure the operating safety of energy systems, which is closely related to efficient cooling methods. Moreover, the application of liquid cooling and phase change cooling still has some questions to solve. Therefore, exploring the cooling issues in new energy systems is particularly important.

This special issue covers:
(1) Efficient cooling methods in new energy systems
(2) Efficient cooling methods in renewable energy systems
(3) Efficient cooling methods in energy storage systems
(4) Thermal management and thermal safety of energy systems
(5) Applications of advanced technologies such as AI in efficient thermal management of energy systems

    Graphical Analysis and 3D Thermodynamic Cycle Construction for Variable-Composition Ejector Refrigeration Cycle

    Anxiang Shen, Xinxin Ren, Tao Wang, Jianqiu Zhou
    Frontiers in Heat and Mass Transfer, DOI:10.32604/fhmt.2026.082573
    (This article belongs to the Special Issue: High Efficiency Cooling Technology in New and Renewable Energy System)
    Abstract To address the growing number of variable-composition ejector refrigeration cycles, this study proposes analyzing the matching performance between working fluids and cycles through 3D (Temperature-Entropy-Mass fraction) Thermodynamic Diagrams. The ejector refrigeration cycle is decoupled into a driving module and a refrigeration module, and a theoretical upper-bound model (COPlimiting) that depends only on working-fluid properties is derived from the T-s diagram. Graph-theoretic analysis yields an explicit relation between COPlimiting and fluid-specific parameters such as Δsb-bsa-b and Δse-e/Δsd-e. Definition of k1T47se-e) and k2T34sb-b) reveals that wet fluids favour the refrigeration module, whereas dry fluids favour the driving module. The influence… More >

    Spray Parameter and Additive Concentration Effects on Smooth Surface Spray Cooling: From Flow Visualization to Nusselt Correlation

    Dawar Asfandyar Khan, Yanyu Chen, Haokang Zhang, Yu Wang
    Frontiers in Heat and Mass Transfer, DOI:10.32604/fhmt.2026.083157
    (This article belongs to the Special Issue: High Efficiency Cooling Technology in New and Renewable Energy System)
    Abstract Efficient thermal management of high heat flux systems is critical in modern electronic and energy devices. Spray cooling, with its high heat removal capability and uniform surface cooling, is widely recognized as an effective technique. Extensive studies have explored spray cooling using water and other working fluids, focusing on droplet dynamics, surface wetting, and heat transfer enhancement. However, the influence of low-concentration alcohol additives on spray cooling performance and evaporation dynamics remains insufficiently understood. This work systematically investigates the non-monotonic heat-transfer behaviour by varying spray height, flow rate, and heat input individually, focusing on the… More >
