Patent attributes
A portable cooling system providing a controlled rate of cooling. The system includes a cool water device, a remote switching unit, and a thermal pad. The cool water device includes a coolant storage chamber separated from a pumping chamber by a baffle. The pumping chamber includes a pump and a discharge line with a flow restrictor for the fluid being returned from the thermal pad. In one embodiment, the remote switching unit actuates the portable cooling system and includes a timer feature for shutting down the system after a predetermined time. In another embodiment, the switching unit actuates a controller that sends a pulse stream to the pump to control the cooling water flow rate. The thermal pad includes fluid conduits that distribute the cooling water over the surface of the pad. In various embodiments, the thermal pad is a flat pad, a bonnet-shaped pad, and a cap-shaped pad.
