A seat air-conditioning system includes a plurality of seat air-conditioning devices respectively disposed for seats. Each of the seat air-conditioning devices achieves comfortable air conditioning in a vehicle interior by a controller controlling a refrigeration circuit, a blower, and a blowing switching portion in each seat air-conditioning device. A coordinating flow path is disposed to fluidly connect the blowing switching portion of one seat air-conditioning device to the blowing switching portion of the other seat air-conditioning device. The seat air-conditioning system performs the air conditioning for one seat by using the two seat air-conditioning devices by supplying conditioned air via the coordinating flow path under control of the controller.

The invention relates to a thermoelectric device (10) with several, differently-doped and electrically-conductively interconnected semiconductors (12), at least one carrier substrate (14) arranged on a first side of the semiconductors (12), and at least one carrier substrate (16a-16d) arranged on a second side, opposite the first side, of the semiconductors (12), wherein at least one carrier substrate (14, 16a-16d) arranged on the first side or the second side of the semiconductors (12) has at least one recess (18a-18d, 20a-20d) which extends through the carrier substrate (14, 16a-16d) and is surrounded by substrate material, and which is designed to receive a fastening means (22a-22d).

A system includes a climate control module and a thermal device control module. The climate control module, based on at least one of a user input and a first input from a temperature sensor that measures a temperature of a seat of a vehicle, generates one of (i) a heating command signal indicating an instruction to heat the seat and (ii) a cooling command signal indicating an instruction to cool the seat. The thermal device control module, in response to one of the heating command signal and the cooling command signal, controls at least one of a blower and at least one TED to one of heat and cool the seat based on a second input from at least one sensor that measures at least one of a pressure applied to the seat, a force applied to the seat, and a strain within the seat.

A thermoelectric fabric may include a plurality of first threads and second threads. The first threads may be alternately formed by p-doped and n-doped thread portions and electrically conductive first thread portions and second thread portions arranged in between. The first thread portions may form a hot side of the fabric, and the second thread portions may form a cold side. The first threads may form one of warp threads or weft threads of the fabric, and the second threads may form the other of the warp threads or weft threads. On at least one of the first thread portions of at least one of the plurality of first threads, a temperature control structure with at least one temperature control element for cooling the hot side may be present.

A heating and cooling device is disclosed comprising at least one integral low voltage heating and cooling source and an efficient flexible heat distribution means having a thermal conductivity of from 375 to 4000 W/mK for distributing the heat and cool across a surface. Further aspects include thermal interface compounds to provide full thermal contact as well as the use of a phase change material to provide a long lasting heating and/or cooling effect without the use of external electrical input. Preferred applications include automotive and furniture seating heating and cooling, along with outdoor garments having distributed heating and cooling effects. Additional aspects include a thermal pad wrap and a thermally conductive liquid system for heat/cool distribution.

A vehicle seat includes a seat bottom and a seat back. The seat back is coupled to the seat bottom and arranged to extend upwardly from the seat bottom. The seat back includes a seat-back frame and a comfort integrator unit to be mounted to the seat-back frame, as well as a seat-cover shell that can be positioned over the mounted comfort integrator unit.

A thermoelectric module has a base and first and second thermoelectric elements set in the base and electrically isolated by the base. A bottom layer is coupled to a bottom surface of the base, a bottom surface of the first thermoelectric element, and a bottom surface of the second thermoelectric element to electrically connect the first and second thermoelectric elements. The base is used to protect the thermoelectric elements. Multiple thermoelectric modules may be mounted to and connected by conductors on a flexible circuit panel to create a flexible thermoelectric circuit assembly for cooling, heating and/or power generating applications.

An automobile seat and an automobile are provided. The automobile seat comprises a seat cushion and a backrest, and at least one of the seat cushion and the backrest is provided with a temperature adjusting system comprising a temperature adjusting device and a fan (300). In the automobile seat, the traditional heating pad and ventilation device are replaced by providing, in a temperature adjusting system, a fan (300) and a temperature adjusting device formed by serially-connected devices wherein a convertible cooling module (100) and a heating module (200) are connected, thereby achieving the integrated design of ventilation heating and cooling, avoiding the interference between the two sets of devices, thus reduces manufacturing and processing costs.

A seat headrest assembly (16) includes a core (54) that includes a core bottom (56). A thermal conditioning device (22) includes a housing (26) that provides a fluid passage (28) that extends to a vent (62). A heating module (36) and a blower (38) are arranged in the fluid passage. The thermal conditioning device is arranged beneath the core bottom.

A seat thermal conditioning device includes a seat portion having a vent configured to provide conditioned air to a seat occupant neck area. A thermoelectric module is arranged in the seat portion. The thermoelectric module is configured to both heat and cool an air supply to provide the conditioned air.
