在大多数热电系统中，热边界条件是瞬态的，并且系统的热管理对于提高系统的电性能至关重要。在这项研究中，使用相变材料（PCM）控制热电发电机（TEG）模块的热端和冷端温度的效果进行了实验研究。为了有一个全面的调查，两个铝盒制作和填充三种类型的PCM。箱应用在三种配置中的TEG模块的热侧、冷侧和两侧。将在系统的不同位置处使用PCM盒的效果与没有PCM的普通TEG系统进行比较。结果表明，在三甘醇模块的热侧应用PCM箱不仅可以使模块在去除外部热源后产生更长时间的电压，而且可以保护模块免受高输入热功率引起的故障。结果表明，使用PCM箱作为散热器是值得的，以提高净发电量，因为在这种情况下，PCM散热器不需要任何冷却能量。
In most thermoelectric systems the thermal boundary conditions are transient, and thermal management of the system is critical to improve electrical performance of the system. In this study, effect of using phase change materials (PCM) to control the hot and cold side temperatures of a thermoelectric generator (TEG) module is investigated experimentally. In order to have a comprehensive investigation, two aluminum boxes are fabricated and filled by three types of PCM. The boxes are applied on the hot side, cold side and both sides of the TEG module in three configurations. The effect of using PCM box at different locations of the system is compared to a common TEG system without the PCM. The results show that, applying PCM box on the hot side of the TEG module not only causes that the module generates voltage for longer time after removing the external heat source, it furthermore protects the module from failure due to high input thermal power. The results indicate that using PCM box as heat sink is worthy in order to enhance the net power generation, because in this case, the PCM heat sink does not need any cooling energy.
