Abstract
A liquid heat transfer device with improved heat transfer into a heating or cooling fluid is disclosed. The heat transfer device incorporates an element which creates a helical flow path through a fluid conduit to more efficiently dissipate heat within a space-constrained environment without increasing the diameter or overall length of the fluid conduit.
Claims20
A liquid heat transfer device, comprising:
- a heat transfer body having a base surface configured to thermally couple to an electronic device;
- a first fluid conduit for a working fluid within the heat transfer body;
- a first helical flow element disposed within the first fluid conduit and defining a helical shape which passes along a length of the first fluid conduit;
- a second fluid conduit adjacent the first fluid conduit within the heat transfer body;
- and
- a second helical flow element disposed within the second fluid conduit;
- wherein:
- the first helical flow element provides at least one helical flow path;
- and
- the first helical flow element is configured to increase turbulence of the working fluid passing through the first fluid conduit.
