Abstract:
1. A heat dissipation device, comprising: a substrate having a surface where a heat absorbing surface is formed, wherein a plurality of hollow conduits are opened inside the substrate, wherein the plurality of hollow conduits form evaporating conduits; condensing conduits communicated with the evaporating conduits, wherein the condensing conduits and the evaporating conduits form sealed conduits, and wherein the sealed conduits are filled with liquid which vaporizes upon heating; vapor manifolds intercommunicated with vapor outlets of the evaporating conduits and with vapor inlets of the condensing conduits; liquid manifolds intercommunicated with liquid inlets of the evaporating conduits and with liquid outlets of the condensing conduits, wherein the liquid manifolds and the vapor manifolds are separated from each other, wherein the vapor inlets are higher than the vapor outlets in position and the liquid inlets are lower than the liquid outlets in position along an upward direction along a line of gravitational effect, and wherein the vapor manifolds and the liquid manifolds are parallel to the line of gravitational effect.
