摘要： A heat dissipation device (1) includes a heat sink (12), a number of first pipes (14), a pair of second pipes (16), and working liquid. The heat sink includes a base (122), and a number of fins (124) attached on the base. A number of parallel first holes (126) is defined through the base. A second hole (128) is defined through a middle of the base in a longitudinal direction that is perpendicular to the first holes. The first and second pipes and the first and second holes thus cooperatively form a closed circulatory route. The working liquid is received in the circulatory route. In operations the working liquid absorbs heat at the base and circulates through the circulatory route. The first and second pipes dissipate said heat to airspace beyond the fins. Accordingly, the first and second pipes increase a heat dissipation area of the heat dissipation device.

摘要： A heat pipe includes an outer pipe (10), an inner pipe (20), and a hermetic cap (30). The outer pipe has an evaporating end (12) and a condensing end (14). The evaporating end is integrally sealed and receives working fluid. The inner pipe includes an open top and an open bottom. A very narrow gap (40) is defined between the inner pipe and the outer pipe. A plurality of granules is put into the gap to form a porous wicking structure. When the evaporating end is heated by an external heat source, the working fluid is vaporized and flows up along the inner pipe to the condensing end. The working fluid condenses at the condensing end, and flows back down to the evaporating end through the gap. Because the gap is very narrow, surface tension of the working fluid and capillary action of the outer and inner pipes is enhanced.

摘要： A heat dissipation device includes a vaporizing portion (10), a condensing portion (20), and a pair of pipes (50a, 50b). The vaporizing portion is attached to a heat-generating electronic chip (40) and contains liquid having great heat conductivity. The condensing portion receives vapor from the vaporizing portion, and cools the vapor to back to liquid form. The pipes are engaged with the vaporizing portion and the condensing portion, thus forming a circulatory route for the vapor from the vaporizing portion to the condensing portion, and for the liquid from the condensing portion to the vaporizing portion.
