Abstract
A network-type heat pipe device is disclosed, wherein the network-type heat pipe device comprises a heat dissipating unit with a network shape, a heat absorbing unit of any desired shape, and two single flexible capillary pipes connecting the heat absorbing unit with the heat dissipating unit. The working fluid filled in the heat pipe is of a predetermined quantity smaller than the internal volume of the heat pipe. The inside diameters of the capillary pipes of the network-shaped heat dissipating unit and the connecting capillary pipes are small enough such that the vapor and liquid segments of the working fluid may distribute therein by capillary effect. As the heat absorbing unit is heated, the mutual actions of the pushing or compression force generated due to the vaporization at the heat absorbing unit, the resisting force generated due to the vapor condensation at the heat dissipating unit, and the gravitational force generated due to the liquid segments in the vertical part of the capillary pipes in the heat dissipating unit and the connecting pipes cause a circulating flow for the working fluid to carry heat from the heat absorbing unit to the heat dissipating unit. The heat absorbing unit can be placed under the heat dissipating unit so as to enhance the gravitational force for circulating the working fluid in the single direction in the flow passage and to increase the heat transport from the heat absorbing unit to the heat dissipating unit.
