“…The HP radiator demonstrated superior isothermal characteristics and safety compared to the pumped loop radiator. In order to enhance the passive cooling capability of the emergency passive residual heat removal system (EPRHR), Qiao et al [56] proposed the use of HPHXs to realize the long-term passive heat exchange of the EPRHR cooling water tank (CWT). Through experiments and numerical simulations, a scheme capable of taking away 9 MW of the heat load at an average water temperature not exceeding 90 • C was proposed.…”

With the reduction in fossil fuels and growing concerns about global warming, energy has become one of the most important issues facing humanity. It is crucial to improve energy utilization efficiency and promote a low-carbon transition. In comparison with traditional heat exchangers, heat pipe heat exchangers indicate high compactness, a flexible arrangement, complete separation of hot and cold fluids, good isothermal operations, etc. As a result, heat pipe heat exchangers have attracted wide attention and application in various fields in recent years. This paper provides an overview of the application of heat pipe heat exchangers, with a focus on the application in waste heat recovery, and analyzes the opportunities and challenges of heat pipe heat exchanger applications based on existing publications.
