Abstract
A heat dissipation device ( ) includes a heat sink ( ), a number of first pipes ( ), a pair of second pipes ( ), and working liquid. The heat sink includes a base ( ), and a number of fins ( ) attached on the base. A number of parallel first holes ( ) is defined through the base. A second hole ( ) 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.
