Abstract
In accordance with one aspect of the invention, a thermal management system for electronics includes a vapor chamber that at least partially envelops the electronics, a working fluid contained within the vapor chamber and used to dissipate heat from a part of a heated portion of the electronics and a precision sintered 3D wick structure independently created on some of the interior of the vapor chamber. The precision sintered 3D wick structure transports the working fluid by capillary action from at least one working fluid receptacle to a part of the heated portion of the electronics. In one embodiment of the invention, the 3D vapor chamber may be formed by the additive manufacturing processes. A further example includes precision sintered 3D support structures integrated into the closed 3D vapor chamber. The support structures mainly facilitate to support the 3D closed vapor chamber envelope from collapsing during operation, and add overall structural strength and additionally facilitate transfer of liquids and gas through their internal 3D porous zones.
