複数のループサーモサイフォン式熱電発電装置間での発電量偏差の抑制

抄録

As a technology of exhaust gas heat recovery, the thermoelectric generator using the loop thermosiphon (LT-TEG) has been developed. The loop thermosiphon can transport exhaust gas heat effectively to the thermoelectric modules. This study has considered installing two LT-TEGs along exhaust gas flow. It is concerned that decrease in the heat input on downstream side causes deviation in the electric output between the two LT-TEGs. To maximize the electric output of both the LT-TEGs, it is necessary to suppress the deviation. To do this, the refrigerant channels of the two LT-TEGs have been connected so that they can share the refrigerant of uniform pressure. Numerical modeling of the joint system and its experimental verification have been performed.
