Submersible warming device

A submersible warming device, comprising:

• an electrically powered fan having an inlet and an outlet;
• an electrically powered pump having a suction, discharge and a pumping chamber therebetween;
• one or more batteries to provide electrical current to operate the fan and the pump;
• a fuel storage container containing a volume of pressurized fuel;
• a fuel feed valve with an actuator to operate the valve and to control the rate at which a stream of fuel is released;
• an oxygen storage container containing a volume of pressurized oxygen;
• an oxygen feed valve with an actuator to operate the valve and to control the rate at which a stream of oxygen is released;
• a heat exchanger having an interior chamber to receive the stream of fuel and the stream of oxygen;
• a catalytic member received within the chamber of the heat exchanger to promote reaction of the fuel and the oxygen to produce heat and reaction by-products;
• a warming conduit having an inlet coupled to the pump discharge, an outlet and a warming portion therebetween disposed in thermal communication with the heat exchanger;
• at least one combustion by-product storage member disposed to receive a discharge stream of combustion by-product gases from the interior chamber of the heat exchanger;
• a cooling conduit including an inlet, and outlet and a cooling portion therebetween coupled to at least one planar fabric member that is adapted for being secured to a human;
• a fluid feed conduit coupled at a first end to the outlet of the warming conduit and at a second end to the inlet of the cooling conduit;
• a fluid return conduit coupled at a first end to the outlet of the cooling conduit and at a second end to the pump suction;
• and
• a volume of fluid disposed within a closed loop including the warming conduit, the cooling conduit, the fluid feed conduit, the fluid return conduit, the pump inlet, the pump outlet, and a pumping chamber intermediate the pump inlet and the pump outlet.
