Abstract:
A heat sink comprising:a body having an envelope including a flexible portion for thermal contact with a heat source a substantially planar rigid surface opposite the flexible portion; and an upper surface that is transverse to the rigid surface and the flexible portion, the envelope being filled with a thermally conductive liquid;a thermosyphon having multiple evaporator portions disposed at least partly within the liquid in the body to absorb heat from the heat source and multiple condenser portions disposed outside the envelope and extending from the upper surface to dissipate heat;a first valve located on the body through which the liquid is charged into the envelope to come into contact with all of the evaporator portions; anda second valve located on the body through which vapor is discharged out of the envelope and away from all of the evaporator portions, such that the envelope is capable of being filled with liquid through the first valve while the vapor is eliminated through the second valve.
