Abstract:
A heat pipe device used in heat transport, comprising:(a) a heat absorbing unit inside of which is a space of any shape for storing working fluid; the heat absorbing unit being used to absorb heat from a heat source, said heat absorbing unit having an inlet and an outlet;(b) a heat dissipating unit formed by network-shape capillary pipes comprising a geometric shape defined by a capillary inlet header pipe having an inlet, a capillary outlet header pipe having an outlet, and a plurality of capillary cross-pipes connecting said inlet and outlet header pipes together to form a plurality of cells, each cell being circumferentially bounded on all sides by a capillary pipe, for releasing the heat transported from the heat absorbing unit to a heat sink;(c) a first connecting capillary pipe connected between the outlet of the heat absorbing unit and the inlet of the inlet header pipe of the heat dissipating unit, and a second connecting capillary pipe connected between the outlet of the outlet header pipe of the heat dissipating unit and the inlet of the heat absorbing unit so as to form a closed loop, said first and second connecting capillary pipes each being made from an extensible metal or nonmetal material;(d) a condensable working fluid filled in the heat absorbing unit, the heat dissipating unit, and the first and second connecting capillary pipes, wherein a quantity of the filled liquid is smaller than a total volume of inner spaces of the heat absorbing unit, the heat dissipating unit and the first and second connecting capillary pipes; and wherein(e) said heat absorbing unit and said heat dissipating unit are disposed other than adjacent to each other.
