    • Apparatus for heating and cooling a steering wheel includes a skin layer coupled to the outside surface of the steering wheel, a heat conductive plate coupled to an inside surface of the skin layer, a thermal storage core extending along a central portion of the steering wheel, and at least one thermoelectric transducer thermally coupled between the heat conductive plate and the thermal storage core. The thermoelectric transducer either generates heat or absorbs heat in accordance with the direction of a current flowing through the transducer. When the steering wheel is hot, current is caused to flow through the transducer in a first direction so that the transducer absorbs heat. The transducer absorbs the heat from the heat conductive plate and passes it to the thermal storage core. In turn, the heat conductive plate absorbs the heat on the skin layer of the steering wheel, thus cooling the steering wheel. When the steering wheel is too cold, the current is caused to flow in a second direction in the transducer so that the transducer generates heat. This generated heat is provided to the heat conductive plate, which in turn, heats the skin layer of the steering wheel.
    • 用于加热和冷却方向盘的装置包括耦合到方向盘的外表面的表皮层,耦合到表层的内表面的导热板,沿着方向盘的中心部分延伸的储热芯, 以及热耦合在所述导热板和所述蓄热芯之间的至少一个热电换能器。 热电换能器根据流过换能器的电流的方向产生热量或吸收热量。 当方向盘热时,使电流在第一方向上流过换能器,从而换能器吸收热量。 换能器吸收来自导热板的热量并将其传递到储热芯。 反过来,导热板吸收方向盘的皮肤层上的热量,从而冷却方向盘。 当方向盘太冷时,电流在换能器中沿第二个方向流动,从而换能器产生热量。 这种产生的热量被提供给导热板,这又导致加热方向盘的表皮层。
