Method and thermally active multi-phase heat transfer apparatus and method for abstracting heat using liquid bi-phase heat exchanging composition
Apparatus for abstracting heat comprises a container charged with a first liquid and with small auxiliary containers free to circulate in the first liquid. Each of the small auxiliary containers is charged with a second liquid. The first and second liquids each have a selected temperature of transformation that facilitates use of the apparatus to heat or cool a substance contacted by the apparatus.
1 . A pliable two phase single wall heat transfer device for use in contacting and drawing heat away from a substance, said heat transfer device comprising
(a) a plurality of matrix units each including
(i) an outer wall circumscribing and enclosing an inner space;
(ii) a plurality of spaced apart hollow fluid tight containers connected to a portion of said wall, extending from said wall into said inner space;
(iii) a first heat-exchange composition in said inner space contacting each of said fluid tight containers and comprising a liquid which undergoes a change of state from the liquid phase to the solid phase at a selected temperature of transformation; and,
(iv) a second heat-exchange composition in each of said hollow containers comprising a liquid which undergoes a change of state from the liquid phase to the solid phase at a selected temperature of transformation;
(b) a fastening system for interconnecting said matrix units along at least a pair of separate spaced apart lines of weakening to enable said heat transfer device to be mounted over the shoulders and around the neck of an individual.

3 . A method for drawing heat away from a substance, said method comprising the steps of
(a) conducting heat from the substance through a first sheet into a first fluid reservoir;
(b) moving heat by liquid convection in said reservoir;
(c) conducting through a second sheet into a second fluid reservoir heat transported by liquid convection in said first fluid reservoir;
(d) moving heat by liquid convection from said second fluid reservoir to said first fluid reservoir.
