    • A heat dissipation device includes a heat sink, a retention module and a rotatable fastener for securing the heat sink to the retention module. The retention module includes two supporting ribs and a positioning block above one of the supporting ribs. The rotatable fastener is rotatably received in the retention module and includes an actuating portion and a pressing portion fastened to the actuating portion. The heat sink rests on the supporting ribs of the retention module with an end thereof being pressed by the positioning block, and an opposite end thereof being pressed by the pressing portion. The rotatable fastener can be rotated to an unlocked position wherein the pressing portion is moved away from the opposite end of the heat sink, so that the heat sink is removable from the retention module.
    • 散热装置包括散热器,保持模块和用于将散热器固定到保持模块的可旋转紧固件。 保持模块包括两个支撑肋和位于一个支撑肋上方的定位块。 可旋转紧固件可旋转地容纳在保持模块中,并且包括致动部分和紧固到致动部分的按压部分。 散热片搁置在保持模块的支撑肋上,其一端被定位块按压,其相对端被按压部分按压。 可旋转紧固件可以旋转到解锁位置,其中按压部分移动远离散热器的相对端,使得散热器可从保持模块移除。

    • A heat dissipation device includes a plurality of fins stacked together, a plurality of heat pipes extending through the fins, and solder filled in gaps between the fins and the heat pipes. Each fin includes a plate defining a plurality of holes therein for extension of the heat pipes therethrough, respectively. A collar extends from a periphery of each of the holes. The collar includes a columned portion attached to an outer surface of each of the heat pipes, and a taper portion interconnecting the plate and the columned portion. The solder fills in a gap between the columned portion and a corresponding heat pipe and a space between the taper portion and the corresponding heat pipe. The collar has a height slightly smaller than a distance between two adjacent fins.
    • 散热装置包括堆叠在一起的多个翅片,延伸穿过翅片的多个热管,以及填充在翅片和热管之间的间隙中的焊料。 每个翅片包括限定多个孔的板,分别用于使热管延伸通过其中。 套环从每个孔的周边延伸。 套环包括附接到每个热管的外表面的柱状部分和将板和柱状部分互连的锥形部分。 焊料填充在柱状部分和对应的热管之间的间隙以及锥形部分和相应的热管之间的空间。 套环的高度略小于两个相邻鳍片之间的距离。
