Thermally conditioned vehicle seat

摘要

A thermoelectric device is disposed in series with the HVAC module for heating and cooling air T_a from the HVAC module for delivery to seat passages of a seat assembly. The thermoelectric device includes a thermoelectric module, a heat exchanger having cold and hot sides, ductwork, a divider that sends variable air flow to the cold or hot sides of the thermoelectric module, and thermal insulation between the cold and hot sides downstream of the heat exchanger. The fan of the HVAC module is the sole motivation for moving the conditioned air T_a originating from the central HVAC module through the thermoelectric device and to the seat assembly.
