Abstract
A heat dissipation device includes a plurality of fin plates (1) and a pair of heat pipes (30). Each fin plate includes a first plate (10) and a second plate (20). The first plate forms a first fastener (15) at an edge thereof and a pair of cutouts (17) at opposite sides of the fastener. A pair of tabs (152) is formed at opposite sides of the first fastener and parallel to the first plate. The second plate forms a second fastener (25) at an edge thereof. The second fastener includes a pair of double-layer latches (252) received in the cutouts of the first plate and interengaged with the tabs of the first plate. The first fastener is located between the pair of latches. The heat pipes are inserted through the first and second plates between said edges. The first and second plates then abut each other at said edges.
