ABSTRACT:
Capillary grooves in a heat pipe which are specifically constructed to suppress boiling. Conventionally shaped grooves are constructed with highly polished surfaces. The high polish discourages vapor bubbles which otherwise interfere with the liqud transport function of the arteries. A method of constructing the highly polished grooves by vapor deposition onto matching mandrels is also disclosed.
