Abstract

Enhancing the functionality of heat pipes can lead to improvement in the efficiency of systems that integrate heat pipes as a component. The heat transfer capacity of heat pipes as well as their thermal performance is greatly influenced by the choice of working fluid. Utilizing nanofluids as working fluids within these devices has the potential to significantly enhance thermal performance. Beyond single nanomaterial nanofluids, hybrid nanofluids (HNFs), which contain multiple nanomaterials, can also be influentially used in heat pipes. The objective of this article is to review applications of HNFs in different types of heat pipes and explore their potential for heat transfer improvement as well as the influential factors on their performance. According to the results of the reviewed studies, there is substantial potential for improvement of heat transfer in these devices by use of HNFs. The outcomes of the present review articles reveal that the extent of enhancement in heat pipes charged with these types of fluids is impacted by some factors such as the specific materials used in the HNFs, the type of heat pipe and the operating conditions. Selecting the right HNFs with optimal concentration can lead to significant performance enhancements in various heat pipes. According to the literature review on the applications of HNFs in heat pipes and applicability of other techniques, like structural modifications, for thermal performance enhancement, it is recommended to consider simultaneous consideration of different modification methods to further enhance the heat transfer characteristics of these devices.
