Abstract:
A liquid immersion cooling apparatus for electronic components, suitable for operation in thermally uncontrolled environments, comprising:a shell having upper and lower portions and defining a chamber within the shell having corresponding upper and lower portions;the lower portion of the chamber containing a low boiling point dielectric liquid partially filling the chamber, the liquid level approximately defining a dividing line between the upper and the lower portions of the chamber and the shell;the lower portion of the chamber containing a plurality of heat dissipating electronic components being immersed in the liquid;the shell having an external heat transfer structure extending outwardly from the shell and an internal heat transfer structure extending from the shell into the chamber;the external heat transfer structure including a side external heat transfer structure provided on a side surface area of the shell, the side external heat transfer structure providing heat transfer from the upper portion of the shell only, thereby ensuring substantially higher efficiency of heat dissipation at high external temperatures than at low external temperatures.
