Abstract: The invention relates to a tibial component (1) of a knee endoprosthesis for anchoring on the proximal tibia, comprising a tibial plateau (2), a tibial shaft (3) on the underside of the tibial plateau (2) facing the tibia, and having a liner (4) for receiving and supporting the lateral condyle surface of a femoral part. To allow different heights and shapes of the liner to be provided medially and laterally, and to ensure that just one individual liner can be exchanged in the event of revision and, for this purpose, a minimally invasive intervention (operation) is sufficient, it is suggested according to the invention that the tibial component (1) has one liner or preferably two liners (4a, 4b) embodied as individual parts, which liner or liners is/are exchangeably anchored on the tibial component (1).

Abstract: A thermoelectric module includes a cold side, a hot side and thermoelectric elements disposed between the two sides. At least one heat conducting layer is disposed between the thermoelectric elements and at least the cold side or the hot side and the heat conducting layer can be compressed. A method for producing a thermoelectric module having at least one heat conducting layer is also provided.

Abstract: A thermoelectric module includes an inner circumferential surface, an axis and an outer circumferential surface. A plurality of semiconductor elements is disposed with thermoelectric material in the direction of the axis and between the inner circumferential surface and the outer circumferential surface and are electrically interconnected in an alternating manner. At least one part of the semiconductor elements has at least one inner frame part or an outer frame part. At least some of the inner frame parts form an interrupted inner circumferential surface or outer frame parts form an interrupted outer circumferential surface.

Abstract: An exhaust gas routing device for an internal-combustion engine having a thermoelectric generator is fluidically connected with an exhaust gas line and a pipe guiding a coolant. The generator has a plurality of thermoelectric yoke pairs which are arranged between a first surface heated by the exhaust gas and a second surface cooled by the coolant. The exhaust gas routing device has a device guiding the exhaust gas along the first surface at a flow velocity that increases in the flow direction of the exhaust gas.

Abstract: A semiconductor element is formed of a thermoelectric material having at least one aperture, a first end face and an opposite second end face. A cross-sectional surface which is parallel to the first end face or to the second end face extends through the thermoelectric material and through the aperture and has an area which is at most 20% greater than the first front surface and is smaller than the second end face. A thermoelectric module having at least two semiconductor elements is also provided.
