TL;DR: In this article, the authors evaluate the feasibility and benefits of using heat pipe technology to cool the turbine vanes of gas turbine engines and show a 7.2% increase in engine thrust, a 0.2 percent decrease in specific fuel consumption with engine weight increased by less than 1% by using this technology.
Abstract: This paper evaluates the basic feasibility and anticipated benefits to using heat pipe technology to cool the turbine vanes of gas turbine engines.This concept involves fitting out the vane interior as a heat pipe, extending the vane into an adjacent heat sink and then transferring the vane incident heat through the vane to the heat sink. The baseline is an advanced military fighter engine and the bypass air is the chosen heat sink. The results of this study show a 7.2% increase in engine thrust, a 0.2% decrease in specific fuel consumption with engine weight increased by less than 1% by using this technology.Copyright © 1994 by ASME

TL;DR: In this article, a wick for use in a heat pipe is provided incorporating particles of micro-encapsulated phase change material bonded together to form the wick, which greatly enhances the ability of the heat pipe to absorb excess heat.
Abstract: A wick for use in a heat pipe is provided incorporating particles of micro-encapsulated phase change material bonded together to form the wick. Use of a wick structure comprising micro-encapsulated PCM particles has the advantage of providing an additional heat absorber. This greatly enhances the ability of the heat pipe to absorb excess heat and may help to prevent damage to the heat pipe or heat generating component, such as an electronic device, especially at times of peak thermal loads.

TL;DR: In this paper, the phase change heat transfer performance of a PCM embedded in a porous metal fiber sintered felt (PMFSF) was investigated, and three types of heat sinks (filled with MF-PCM, filled with paraffin, and empty) were tested under four power levels.

TL;DR: In this article, the authors focus on the systems that use a combination of phase change materials (PCM) and heat pipes to enhance thermal performance and efficiencies, and report that overall efficiency, heat storage and release rate of PCM is reported to greatly improve by the integration of heat pipe.
Abstract: Phase change materials (PCMs) have huge potential for latent thermal energy storage, waste heat recovery, heating, and cooling systems, due to their excellent thermal storage properties. However, the low thermal conductivity is most significant problem related with the PCMs, which retards the heat transfer rate and limits their practical applications. Heat pipe (HP) is extensively used heat transferring device, due to their ability to transfer heat isothermally over small and large distances. This review focuses on the systems that use a combination of PCM and heat pipes to enhance thermal performance and efficiencies. Overall efficiency, heat storage and release rate of PCM is reported to greatly improve by the integration of HP. These hybrid systems also have shown to overwhelm the issues such as low thermal conductivity of PCM and overheating of heat pipes.
