A hermetically sealed housing includes a plurality of inner walls extending radially from a central post to a circular outer wall, thereby defining a plurality of pie shaped chambers, each independently containing a refrigerant. At least one of the chambers is always in position to remove heat from an electronic device regardless of the orientation of the heat exchanger assembly. A plurality of side fins are disposed on the outer wall of the housing, and a plurality of top fins extend radially from a central axis (A) and are disposed on top of the housing. A wicking material is disposed on the interior of each chamber. A fan assembly is disposed on top of the top fins to blow air radially down into the fins.

What is claimed is: 1. An orientation insensitive heat exchanger assembly for cooling an electronic device comprising; a boiler plate for transmitting heat from an electronic device, a hermetically sealed housing defining a plurality of independently sealed chambers, wherein said housing includes a top wall and a bottom wall and at least one outer wall disposed about a central axis (A) and a plurality of inner walls intersecting at said central axis (A) and extending radially from said central axis (A) to said outer wall, a refrigerant disposed in each of said chambers of said housing for liquid to vapor transformation of said refrigerant in each of said chamber independent of said refrigerant in other said chambers, a plurality of side fins equally spaced from one another circumferentially around said outer wall, and a plurality of charge ports disposed on said outer wall of said housing interleaved with said side fins with each of said chambers being associated with one of said charge ports for supplying liquid to each of said chambers. 2. An assembly as set forth in claim 1 including a thermal grease on a bottom surface of said boiler plate for engaging an electronic device. 3. An assembly as set forth in claim 1 including a plurality of top fins extending upwardly from said top wall of said housing and extending radially outwardly from said central axis (A) to second outer edges at an outer imaginary cylinder (C) having a circular cross-section for dissipating heat from said top wall. 4. An assembly as set forth in claim 3 including a fan assembly disposed on said top fins for blowing air downwardly onto said top wall. 5. An assembly as set forth in claim 4 including a plurality of fan blades disposed about said central axis (A) for blowing air and a shroud having a cylindrical shape having a circular cross-section disposed on said top fins and surrounding said fan blades and a motor for rotating said fan blades and a cage extending radially inwardly from said shroud and supporting said motor. 6. An orientation insensitive heat exchanger assembly for cooling an electronic device comprising: a boiler plate for transmitting heat from an electronic device, a thermal grease for disposition between a bottom surface of said boiler plate and an electronic device, a hermetically sealed housing having a cylindrical shape having a circular cross-section disposed about a central axis (A), said housing being hermetically sealed by having at least one outer wall and a bottom wall and a top wall sealed to one another, a plurality of inner walls extending radially from said central axis (A) to said outer wall to define a plurality of pie shaped chambers disposed in said housing and each extending radially from said central axis (A) to a curved segment of said outer wall, a post disposed about said central axis (A) extending from said bottom wall upwardly to said top wall, a plurality of interior fins disposed on said post and extending radially outwardly from said top wall to said bottom wall with each of said interior fins being associated with one of said chambers, a wicking material disposed on an interior surface including said top wall and said bottom wall and said outer wall of said chambers, a refrigerant disposed in each of said chambers of said housing for liquid to vapor transformation, a plurality of side fins equally spaced from one another circumferentially around said outer wall, said side fins extending radially outwardly from said outer wall to axially extending first outer edges at an outer imaginary cylinder (C) having a circular cross-section and from said top wall to said bottom wall for dissipating heat from said refrigerant in said chambers, a plurality of charge ports disposed on said outer wall of said housing interleaved with said side fins with each of said chambers being associated with one of said charge ports for supplying liquid to each of said chambers, a plurality of top fins equally spaced from on another and extending upwardly from said top wall of said housing and extending radially outwardly from said central axis (A) to second outer edges at said outer imaginary circular cylinder (C) for dissipating heat from top wall, a fan assembly disposed on said top fins for blowing air downwardly into and radially outwardly between said top fins, said fan assembly including a plurality of fan blades disposed about said central axis (A) for blowing air and a shroud having a cylindrical shape having a circular cross-section disposed on said top fins and surrounding said fan blades and a motor for rotating said fan blades and a cage extending radially inwardly from said shroud and supporting said motor. 7. An assembly as set forth in claim 6 wherein said post has a conical shape. 8. An assembly as set forth in claim 6 wherein said post has a cylindrical shape having a circular cross-section.
