Abstract
A heat pipe is equipped with a bubble trap. Such bubble trap takes the form of a baffle that restricts the liquid flow in the liquid flow channel of the heat pipe to divide the two-phase flow in the liquid channel into a liquid flow and into a bubble and liquid flow. A cage of wire mesh is positioned downstream of the baffle to entrap the bubbles. In another embodiment the bubble trapping cage is a chamber that extends all the way into the evaporating end of the pipe while the baffle is arranged upstream of such a chamber which is additionally connected through perforations to the liquid flow channels.
