    摘要: A heat conversion device according to an embodiment of the present invention comprises: a frame comprising multiple unit modules arranged in a first direction and in a second direction intersecting with the first direction, respectively, and a first cooling water inflow tube and a first cooling water discharge tube formed along the first direction so as to support the multiple unit modules; multiple second cooling water inflow tubes connected to the first cooling water inflow tube and arranged on one side of the multiple unit modules along the second direction; and multiple second cooling water discharge tubes connected to the first cooling water discharge tube and arranged on the other side of the multiple unit modules along the second direction. Each unit module comprises a cooling water passage chamber, a first thermoelectric module arranged on a first surface of the cooling water passage chamber, and a second thermoelectric module arranged on a second surface of the cooling water passage chamber. A cooling water inflow port is formed on a third surface between the first and second surfaces of the cooling water passage chamber. A cooling water discharge port is formed on a fourth surface between the first and second surface of the cooling water passage chamber. The cooling water inflow port is connected to the second cooling water inflow tubes, and the cooling water discharge port is connected to the second cooling water discharge tubes.

    摘要: A low heat flux flexible thermoelectric generator woven with semiconducting strings. The thermoelectric strings have a repeated structure of (metal)-(p-type semiconductor)-(metal)-(n-type semiconductor) materials and are formulated with a continuous structure forming a module. In this woven structure, the thermoelectric strings are the warp threads and the insulator strings are the weft yarns. The p-type and n-type stripes are aligned to the same dimensions. A metal terminal at the end of the strings provides the electrical connections in a series with a serpentine pattern. Two electrically insulating films laminated on the top and bottom of this woven structure conduct the surface heat to the metal junctions on both the hot and cold sides. The small fill factor (low fractional area coverage of the thermoelectric leg) creates a high internal thermal resistance that is better matched to low heat flux sources such as human body for harvesting the maximum power output.

    摘要: A thermoelectric generation unit according to the present disclosure includes a plurality of thermoelectric generation tubes. Each tube has a flow path defined by its inner peripheral surface, and generates an electromotive force in an axial direction based on a temperature difference between its inner peripheral surface and outer peripheral surface. The thermoelectric generation unit includes a container housing the tubes inside, and a plurality of electrically conductive members providing electrical interconnection for the tubes. The container includes a shell surrounding the tubes and a pair of plates being fixed to the shell and having a plurality of openings, with channels being formed so as to house the electrically conductive members and interconnect at least two of the openings. The respective ends of the tubes are inserted in the openings of the plates. The tubes are connected electrically in series by the electrically conductive members housed in the channels.

    摘要: A process for manufacturing a nanocomposite thermoelectric material having a plurality of nanoparticle inclusions. The process includes determining a material composition to be investigated for the nanocomposite thermoelectric material, the material composition including a conductive bulk material and a nanoparticle material. In addition, a range of surface roughness values for the insulating nanoparticle material that can be obtained using current state of the art manufacturing techniques is determined. Thereafter, a plurality of Seebeck coefficients, electrical resistivity values, thermal conductivity values and figure of merit values as a function of the range of nanoparticle material surface roughness values is calculated. Based on these calculated values, a nanocomposite thermoelectric material composition or ranges of compositions is/are selected and manufactured.
