Abstract
Abstract A cooling apparatus for personal or general use is disclosed having interior and exterior surfaces and a fluid for dispersion by the exterior surface. The interior surface prevents the fluid from penetrating the interior surface and contacting the person or object to be cooled. The cooling apparatus may also include a fluid collector to collect excess cooling fluid, a device for moving the fluid from the fluid container to the fluid collector, and a return line for recycling at least a portion of the collected fluid. The exterior surface may be wetted by gravity seepage, capillary action, or the like. A band extending around each collector can aid in preventing the fluid from dripping from the apparatus.
