Title: THERMOELECTRIC POWER GENERATION HEAT EXCHANGER
Abstract:
This thermoelectric power generation heat exchanger (10) is provided with: a high-temperature fluid channel (14) in which a high-temperature fluid flows; a low-temperature fluid channel (15) in which a low-temperature fluid that is at a lower temperature than the high-temperature fluid flows; a power generation module (16) which is arranged between the high-temperature fluid channel and the low-temperature fluid channel and generates electric power by means of the heat that is transferred from the high-temperature fluid to the low-temperature fluid; and a heat transfer sheet (18) which is arranged between the high temperature-side surface (16A) of the power generation module and the high-temperature fluid channel. The heat transfer sheet is formed by laminating a central part (18A) and a pair of surface parts (18B) that are arranged so as to closely adhere respectively to the high-temperature fluid channel-side surface and the low-temperature fluid channel-side surface of the central part. The elasticity of the surface parts is higher than that of the central part; and the thermal conductivity (λ) of the central part in the surface direction is higher than that of the surface parts.
