Solar desalination is one of the crucial methods to convert brackish water to freshwater. The major issue of solar desalination is the low water production rate, and for this reason, several studies have been performed on increasing the productivity of solar desalination with active methods, including heat pipe (thermosyphon, pulsating), energy storage material, photovoltaic/thermal, etc. The operating fluid into the heat pipe/pulsating heat pipe evaporates as the temperature increases in the evaporation area and flows to the condensation area. After transferring the heat to the outside, working fluid recycles from the heat pipe walls into the evaporation zone. A heat pipe is a practical and easy-to-use device for transferring heat from a high-temperature energy application to water in solar desalination and to enhance the evaporation rate. This study aims to review the performance of solar desalination systems with heat pipes and pulsating heat pipes. Also, a comprehensive effort has been dedicated to comparing the working fluids of the heat pipe/pulsating heat pipe in different configurations of solar desalination. Moreover, a brief economic analysis of previous studies has been presented for a cost-effective design of solar desalination using thermosyphon heat pipes and pulsating heat pipes. The results indicated that the optimum filling ration of water as a working fluid in pulsating heat pipe was about 40 %. Also, the lowest CPL was achieved in solar desalination with heat pipe evacuated tube, which was about 0.0092 $/L. In addition, the highest improve in productivity was occurred in solar desalination with THP and external condenser, which was 2.13 times more than conventional ones.

太阳能海水淡化是将微咸水转化为淡水的重要方法之一。太阳能海水淡化的主要问题是产水率低，为此，已经进行了多项研究以提高太阳能海水淡化的生产力，包括热管（热虹吸管、脉动）、储能材料、光伏/热能等。进入热管/脉动热管的工作液随着蒸发区温度的升高而蒸发，并流向冷凝区。将热量传递到外部后，工作流体从热管壁循环到蒸发区。热管是一种实用且易于使用的装置，用于将高温能量应用中的热量传递到太阳能淡化中的水，并提高蒸发率。本研究旨在审查带有热管和脉动热管的太阳能海水淡化系统的性能。此外，还致力于比较不同太阳能海水淡化配置中的热管/脉动热管的工作流体。此外，对使用热虹吸热管和脉动热管的太阳能海水淡化的成本效益设计进行了对先前研究的简要经济分析。结果表明，作为工作流体的水在脉动热管中的最佳填充率为40%左右。此外，在太阳能热管真空管海水淡化中，CPL 最低，约为 0.0092 美元/升。此外，使用 THP 和外部冷凝器的太阳能海水淡化的生产率提高最高，为 2。
