Against the backdrop of the “dual carbon” strategy, enhancing energy utilization efficiency and promoting low-carbon urban heating have become key directions for energy system transformation. Due to the compact structure, high heat transfer efficiency, and strong adaptability, herringbone plate heat exchangers have emerged as critical intermediate heat exchange equipment in long-distance heating systems. This paper reviews research on the heat transfer performance of herringbone plate heat exchangers, systematically examining fluid flow patterns within plate heat exchangers and the mechanisms influencing thermohydraulic performance under single-phase and two-phase flow conditions, along with recent advancements. First, factors affecting fluid flow within herringbone corrugated plates are introduced. Subsequently, recent experimental and numerical simulation advancements under single-phase and two-phase conditions are presented, along with corresponding performance correlation equations. In contrast, two-phase heat transfer mechanisms are more complex, with relatively insufficient research and a lack of universally applicable theoretical models and performance correlations. This paper argues that future efforts should focus on strengthening research into two-phase flow heat transfer mechanisms and developing more universal and predictive performance models to support the efficient application of plate heat exchangers in low-carbon heating and industrial energy conservation.
