Definitions

  • FIG. 8 is a perspective view of a heat sink according to some embodiments of the present disclosure.
  • the radiator 26 may transfer heat to the atmosphere by any means such as radiation, conduction, and/or convection.
  • the radiator 26 includes a skin 32 of melted material formed by additive manufacturing, with the skin 32 and enclosing a chamber 36.
  • the skin 32 may be formed by selectively melting a source material, such as a loose powder, using a concentrated heat source, such as a laser.
  • the second example heat sink 120 is similar to the first example heat sink 20, with some additional design features.
  • the radiator 26 is formed as a monolithic piece by additive manufacturing.
  • the second example heat sink 120 includes an outer wick 38 of porous material disposed within the chamber and coating an inner surface 34 of the skin 32.
  • the outer wick 38 comprises material melted or partially melted material by additive manufacturing.
