Flat or curved micro heat pipe panels are fabricated by arranging essentially parallel filaments in the shape of the desired panel. The configuration of the filaments corresponds to the desired configuration of the tubes that will constitute the heat pipes. A thermally conductive material is then deposited on and around the filaments to fill in the desired shape of the panel. The filaments are then removed, leaving tubular passageways of the desired configuration and surface texture in the material. The tubes are then filled with a working fluid and sealed. Composite micro heat pipe laminates are formed by layering individual micro heat pipe panels and bonding them to each other to form a single structure. The layering sequence of the micro heat pipe panels can be tailored to transport heat preferentially in specific directions as desired for a particular application.

A method of forming micro heat pipe panels having a desired shape and having a desired heat pipe configuration and texture, comprising the steps of: a. arranging at least one layer of substantially parallel filaments such that the filament arrangement corresponds to the desired shape of the micro heat pipe panel, wherein the size, shape and texture of the filaments correspond to the desired heat pipe configuration and texture, and the filaments are stable during the subsequent deposition step; b. depositing a thermally conductive material on and around the filaments to form the desired shape of the micro heat pipe panel; c. removing the filaments from the thermally conductive material to produce tubular passageways within the deposited material, each of the tubular passageways having ends with at least one end open; d. partially filling the tubular passageways with a working fluid; and e. sealing the ends of the tubular passageways to prevent loss of the working fluid.
