Abstract
A heat pipe includes an air tight elongated container and a heat carrier sealed in the container. The elongated container has a flat bottom wall serving as a heat receiving portion and a top wall serving as a heat dissipating portion. A liquid passage for moving condensed heat carrier in a slanted direction and parallel directions with respect to the longitudinal axis by capillary action is provided on the inner wall surfaces of the container. The heat carrier which has been condensed into liquid flows along the liquid passage to be distributed entirely over the bottom wall surface where it efficiently absorbs heat to be evaporated again.
Claims9
A heat pipe, comprising an air tight elongated container having a longitudinal axis, a flat bottom wall forming a heat receiving portion and a top wall opposite said bottom wall, and side walls interconnecting said top and bottom walls extending in a longitudinal direction;
- a heat carrier fluid sealed in said container;
- liquid passage means on inner wall surfaces of said container for moving by capillary action condensed heat carrier fluid in directions at a slant and in parallel to said longitudinal axis, at least one of said side walls having an inwardly concave shape with outwardly reaching side wall edges joined to said bottom wall and to said top wall to form an acute corner along each of said top wall and said bottom wall, each corner defining an inwardly open capillary groove for transporting condensed heat carrier fluid in a direction parallel to said longitudinal axis by capillary action.
