A heat dissipation device includes a plurality of fin plates () and a pair of heat pipes (). Each fin plate includes a first plate () and a second plate (). The first plate forms a first fastener () at an edge thereof and a pair of cutouts () at opposite sides of the fastener. A pair of tabs () is formed at opposite sides of the first fastener and parallel to the first plate. The second plate forms a second fastener () at an edge thereof. The second fastener includes a pair of double-layer latches () 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.

Heat dissipation device with interlocking fin plates

A heat dissipation device () includes a heat dissipation member (), a positioning member () and a mating member (). The heat dissipation member includes a fin set () and a post () in the fin set. The post extends through the positioning member and is mated with the mating member so that the positioning member is positioned between the fin set and the mating member.

Heat dissipation device

A heat dissipation device includes a base () having a heat dissipating surface, a plurality of fins () and a pair of heat pipes (). The fins cooperatively define a concave tunnel in a side thereof. The heat dissipating surface of the base is embedded in the tunnel of the fins. Each heat pipe has a vaporizing portion () engaged with the base and a condensing portion () engaged in the fins.

A heat dissipation assembly includes a heat sink (), a fan () and a fan holder (). The heat sink includes a plurality of fins () and defines a groove () in the fins at a base end thereof. The holder includes a bracket (). The fan is secured to a first main side of the bracket. A locating flange () is formed adjoining an edge of a second main side opposite to the first main side of the bracket. A pair of locking flanges () is formed adjoining opposite edges of the second main side of the bracket, disposed at opposite sides of the locating flange. The locating and locking flanges are received in the groove of the heat sink and abuttingly engaged with an inner defined at the heat sink in the groove. The base end of the heat sink is received between the bracket and the flanges.
