A cooling device and method for cooling a rotating wheel that has an outer periphery generating heat as it contacts another surface. The cooling device is a sealed tubular member partially filled with a volatile liquid that vaporizes as it contacts heat from the outer periphery of the wheel. The vapor rises to an opposite end of the tubular member where it condenses as it is cooled and returns to the first end of the tubular member due to centrifugal force of the rotating wheel. This cycle repeats and is a continuous cooling process. The tubular member may be a conventional capillary heat pipe extending through the rim of a vehicle wheel so the first end absorbs tire heat and the other end rejects heat to the air.
