A beverage making machine having a tank may be arranged to carbonate and/or chill liquid in the tank. A thermoelectric device may be thermally coupled to the tank to cool precursor liquid in the tank, and a heat pipe may transfer heat from the thermoelectric device to a heat sink. The heat sink may be located remotely from the thermoelectric device, e.g., in an air duct that helps prevent contact of moisture, dirt, etc. in the duct with the thermoelectric device.

Methods and apparatus for processing flexible graphite sheet material involve patterning the material, on at least one major surface, prior to further processing of the material such as densification, lamination, folding or shaping into three-dimensional structures. For densification and lamination, the patterning is selected to facilitate the removal of air from the flexible graphite sheet material during the densification and lamination process. For folding or shaping, the patterning is selected to render the graphite sheet material more flexible. In some embodiments, methods for increasing the through-plane conductivity of flexible graphite sheet material are employed. Integrated heat removal devices include sheets of graphite material that have been selectively patterned in different regions to impart desirable localized properties to the material prior to it being shaped or formed into an integrated heat removal device. Coatings and/or resin impregnation can also be used to impart desirable properties to the material or device.
