A system for retaining and controlling the temperature of a beverage, suitable for installation in an automobile, includes a generally cylindrical, open-topped heat-conductive expandable cupholder, a heat-conductive liner, one or more thermoelectric devices located on a vertical exterior side of the cupholder, a heat sink contacting the thermoelectric device and thermally insulated from the cupholder; and a switch. The placement of the thermoelectric device and an improved arrangement for contact between the cupholder and the cup enable more efficient heat transfer.

What is claimed is: 1. A system for retaining and controlling the temperature of a beverage, comprising: a generally cylindrical, open-topped heat-conductive cupholder for contacting and supporting the beverage in a container disposed on an interior thereof; a heat-conductive liner for providing a substantially continuous containment surface disposed within the cupholder and interposed between the cupholder and the beverage container; a thermoelectric device disposed on a vertical exterior side of the cupholder and connected to a power source for powering the thermoelectric device; a heat sink contacting the thermoelectric device and thermally insulated from the cupholder; and a switch for selectively actuating and deactuating the thermoelectric device to heat or to cool the cupholder. 2. A system according to claim 1, wherein the cupholder comprises a plurality of cupholder units mergeable to form a cylindrical cupholder. 3. A system according to claim 2, wherein each of the cupholder units is mounted to a fame. 4. A system according to claim 3, wherein the cupholder is expandable by separating the cupholder units from each other, and the cupholder units are urged toward merger thereof. 5. A system according to claim 4, wherein the liner is expandable and contractable with the cupholder. 6. A system according to claim 3, wherein each of the cupholder units comprises mounting pins and the frame comprises a set of grooves for receiving the mounting pins. 7. A system according to claim 1, wherein the switch is configured to be disposed in at least an off position, a heating position representing a first polarity of the power source across the thermoelectric device for inducing heating of the cupholder, and a cooling position representing a second polarity opposite the first polarity for inducing cooling of the cupholder. 8. A system according to claim 1, further comprising a fan for drawing air across the heat sink. 9. A system according to claim 1, wherein the switch comprises a thermostat for selectively actuating or deactuating the thermoelectric device according to a temperature of the cupholder. 10. A system according to claim 1, further comprising at least one additional thermoelectric device. 11. A cupholder system for an automobile, comprising: a frame mounted within a console of the automobile and accessible from a passenger seat within the automobile; a cupholder mounted within the frame, the cupholder being generally cylindrical and formed of a heat-conductive material and including a heat-conductive liner therein; at least one thermoelectric device mounted upon and contacting an outside vertical wall of the cupholder, the thermoelectric device being connected to a power supply within the automobile; a finned heat sink attached to each of the at least one thermoelectric device and disposed about and thermally isolated from the cupholder; and a switch for selectively actuating the thermoelectric device to alter the temperature of the cupholder to cool or heat a beverage container placed on the interior of said cupholder. 12. A cupholder system according to claim 11, wherein the cupholder is expandable to accommodate beverage containers of different sizes within a selected range and biased into contact with an exterior surface of the beverage container. 13. A cupholder system according to claim 11, further comprising a fan for drawing ambient air across the heat sink through vents in the frame. 14. A cupholder system according to claim 11, further comprising means for removing condensation from an exterior surface of the cupholder. 15. A cupholder system according to claim 14, wherein the means for removing condensation includes a fan and a vent disposed along a bottom portion of the frame. 16. A system for retaining and controlling the temperature of a beverage, comprising: a generally cylindrical, open-topped heat-conductive cupholder for contacting and supporting the beverage in a container disposed on an interior thereof, the cupholder being mounted to a frame and expandable and contractable to accommodate beverage containers of different sizes while maintaining substantially full-face contact between the cupholder and the beverage container; a heat-conductive liner disposed win the cupholder and interposed between the cupholder and the beverage container, the liner being expandable and contractable with the cupholder; a thermoelectric device disposed on a vertical exterior side of the cupholder and connected to a power source for powering the thermoelectric device; a heat sink contacting the thermoelectric device and thermally insulated from the cupholder; a switch for selectively actuating and deactuating the thermoelectric device to heat or to cool the beverage according to a selected position of the switch; a fan for drawing ambient air across the heat sink; and a plurality of vents within the frame for permitting the ambient air to be introduced into the interior of the frame.
