Title:
THERMOELECTRIC POWER GENERATION DEVICE
Document Type and Number:
Japanese Patent JP2017017903
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoelectric power generation device capable of sufficiently absorbing a stress to a thermoelectric element 6s caused by thermal expansion of a portion where a high-temperature fluid F1 flows.SOLUTION: The thermoelectric power generation device comprises: a high-temperature container 1 in which the high-temperature fluid F1 flows; and a low-temperature container 5 in which a low-temperature fluid F2 flows. The thermoelectric power generation device also comprises the thermoelectric element 6s including a high-temperature-side part 6sH which performs heat transfer with the high-temperature container 1, and a low-temperature-side part 6sL which performs heat transfer with the low-temperature container 5. The thermoelectric power generation device further comprises a high-temperature container coupling member 7 of which one end is coupled to the high-temperature container 1, another end 7L extends along an outer circumference of the low-temperature container 5 and the position relative to the low-temperature container 5 is changed by heat deformation of the high-temperature container 1. Moreover, the thermoelectric power generation device comprises a stress absorption member 8 which is provided between the other end 7L and the outer circumference of the low-temperature container 5 and absorbs the stress that the high-temperature container coupling member 7 gives to the low-temperature container 5 with the heat deformation of the high-temperature container 1.SELECTED DRAWING: Figure 1
