Abstract
A corrugated fin heat pipe and method of fabrication. The micro channel heat pipe includes a tubular housing split longitudinally into two halves. A pair of corrugated fin elements defining a plurality of adjacent closed and open micro capillary channels are attached to the inner surface of the housing halves. Material is removed from the closed micro capillary channels along a portion of the longitudinal axis to create regions consisting entirely of open micro capillary channels, maximizing heat flux in those regions. The housing halves are reattached and the heat pipe housing is enclosed by a pair of end caps.
