In accordance with the principals of the present invention, a cold tube is adapted to securely surround the beverage can, the cold tube utilizing high heat capacity/thermal mass to wick heat from the beverage in the beverage can. Contained within the cold tube, a plurality of fins are provided thus acting as a heatsink. The presence of the fins act as a heatsink by increasing convective, conductive, and radiative heat dissipation if used in the absence of the cold tube and conductive heat dissipation if used with the cold tube.

An improved portable cooler can be configured to provide access to its contents from multiple orientations while reducing the likelihood of water spillage or contamination. The improved portable cooler may optionally include one or more sliding compartments to allow access to the contents of the portable cooler when the cooler is arranged in any of a horizontal or vertical orientation.

A helmet cooling system includes a reservoir for holding a chilled medium and includes fan that that draws ambient air into the reservoir so that the air will pass over the chilled medium and exit the reservoir through a tube that is connected to a helmet. The helmet includes several channels for distributing the chilled air to the wearer's head to help keep the wearer comfortable. The reservoir can include a diverter valve to preserve the chilled medium when it is not necessary by sealing off the chilled medium and preventing air from circulating past it or otherwise contacting the chilled medium.
