Abstract

A three dimensional vapor chamber is disclosed which has a horizontal vapor chamber portion and a vertical flat heat pipe portion. The interiors of the two portions are in fluid communication and can have a wick material saturated with a working fluid such as water. The vertical flat heat pipe portion can also have fins or other heat exchange structure connected to the exterior thereof to increase heat transfer away from the heat pipe portion. In operation, the vapor chamber portion is placed in contact with a heat source, thus causing the working fluid to evaporate and move into the vertical flat heat pipe portion, where it is condensed. The fluid is then transported back to the vapor chamber portion via capillary action through the wick. The interiors of the two portions may be constructed as a vacuum chamber, so that evaporation of the working fluid can occur at lower temperatures than would occur at atmospheric pressure.
