A cooling apparatus (10) includes a housing defined by two aluminum parts (12, 13) which are brazed to each other. A plurality of sector-shaped recesses (21-28) are provided within the housing, and collectively define a chamber having a plurality of ribs (41-48) extending therethrough. Each recess contains a sector-shaped piece of porous material (17, 18), which is brazed to surfaces of the housing parts. The remaining space within the chamber is filled with a phase change material. Each of the ribs has therein a respective radially extending opening (101-108) which contains a heat pipe (141). Expansion accumulators (151) are mounted on the housing, and communicate with the chamber therein, in order to accommodate expansion of the phase change material within the chamber as the phase change material is heated.

What is claimed is: 1. An apparatus, comprising: a housing having a chamber therein, and having thereon an exterior surface through which heat can enter and leave said housing; a heat absorbing material disposed within said chamber in said housing; a heat pipe disposed completely within the chamber
What is claimed is: 1. An apparatus, comprising: a housing having a chamber therein, and having thereon an exterior surface through which heat can enter and leave said housing; a heat absorbing material disposed within said chamber in said housing; a heat pipe disposed completely within the chamber and disposed within the material of said housing and operative to facilitate heat distribution within the material of said housing in a manner which reduces temperature gradients across said surface; and wherein said housing has a thermally conductive portion with an opening therein, said opening being free of communication with said chamber, and wherein said heat pipe is disposed within said opening in said thermally conductive portion. 2. An apparatus according to claim 1, wherein said heat absorbing material is a phase change material. 3. An apparatus, comprising: a housing having a chamber therein, and having thereon an exterior surface through which heat can enter and leave said housing; a heat absorbing material disposed within said chamber in said housing; a heat pipe disposed completely within the chamber and disposed within the material of said housing and operative to facilitate heat distribution within the material of said housing in a manner which reduces temperature gradients across said surface; and a plurality of further heat pipes; wherein said housing includes a plurality of thermally conductive ribs extending within said chamber and each having therein an opening; and wherein each said opening has therein a respective one of said heat pipes, said further heat pipes each facilitating heat distribution within said housing in a manner which reduces temperature gradients across said surface. 4. An apparatus according to claim 3, wherein each said opening has a first end which communicates through a passageway in said housing with a location external to said housing. 5. An apparatus according to claim 3, wherein each said opening has a second end which is remote from said first end and which opens outwardly through an outer surface of said housing. 6. An apparatus, comprising: a housing having a chamber therein, and having thereon an exterior surface through which heat can enter and leave said housing; a heat absorbing material disposed within said chamber in said housing; means for distributing heat within the material of said housing in a manner which reduces temperature gradients across said surface, said means including a heat pipe disposed completely within the chamber and disposed within the material of said housing; and wherein said means includes said housing having a thermally conductive portion with an opening therein, said opening being free of communication with said chamber, and wherein said heat pipe is disposed within said opening in said thermally conductive portion. 7. An apparatus according to claim 6, wherein said heat absorbing material is a phase change material. 8. An apparatus according to claim 6, wherein said means includes a plurality of further heat pipes, and includes said housing having a plurality of thermally conductive ribs which each extend within said chamber and which each have therein an opening; and wherein each said opening has therein a respective one of said heat pipes. 9. An apparatus according to claim 8, wherein each said opening has a first end which communicates through a passageway in said housing with a location external to said housing. 10. An apparatus according to claim 9, wherein each said opening has a second end which is remote from said first end and which opens outwardly through an outer surface of said housing. 11. An apparatus according to claim 4, including an antenna system which engages said surface on said housing and which generates heat that is transferred through said surface to said housing. 12. An apparatus according to claim 4, including in said chamber within said heat absorbing material a thermally conductive member made of a porous material. 13. An apparatus according to claim 12, wherein said housing and said thermally conductive member are made of a metal, and wherein said thermally conductive member is brazed to surfaces of said housing which define said chamber. 14. An apparatus according to claim 12, wherein said heat absorbing material is a phase change material.
