  • Publication number: 20130174578
    Abstract: Aspects of the invention support simultaneous operation of a cooling side and a heating side of an apparatus to change the temperatures of a cooling serving surface and a heating serving surface, respectively. A cooling semiconductor device (which may comprise one or more Peltier devices) transfers heat from its top to its bottom while a heating semiconductor device (which may similarly comprise one or more Peltier devices) transfers heat from its bottom to its top. A heat pipe transfers waste heat from the cooling semiconductor device's bottom to the heating semiconductor device's bottom and waste cold from the heating semiconductor device's bottom to the cooling semiconductor device's bottom.

The interim heating/cooling device uses the Peltier effect to transfer heat between first and second sides depending on a polarity of current. Controlling which of the two sides is heated provides the desired heating or cooling of the air. Once the heating or cooling system reaches the desired state of readiness, the interim heating/cooling device is turned off.
