摘要:
By using a base in cooperation with a moving board, a first flowing area formed by a plurality of openings on the base may be partially blocked by the moving board moving relative to the base, thereby forming a second flowing area that provides different flow resistances. The flow resistance of an adjustable flow resistance device can be adjusted easily and dynamically, without replacing to another device. The flow resistance of the device may also be adjusted to various predefined default settings precisely and speedily by further applying a positioning mechanism that utilizes various predefined positioning holes or a rotary element.

A heat dissipating mechanism includes a housing. A hollow space is formed inside the housing. The heat dissipating mechanism further includes an airflow guiding structure installed inside the hollow space for separating the hollow space into a first channel and a second channel. An inlet and an outlet are formed on the airflow guiding structure. Airflow enters the first channel via the inlet and jets out of the outlet for mixing with thermal current generated by a heat source in the second channel.

A heat dissipating device includes a base, a heat pipe disposed on the base, and a plurality of first and second heat dissipating fins. Each first heat dissipating fin includes a fin body having a first through hole for extension of the heat pipe therethrough. The first and second heat dissipating fins are mounted on the heat pipe in a stack and in a spaced-apart alternating arrangement. Each second heat dissipating fin includes a fin body having a second through hole for extension of the heat pipe therethrough, two adjacent lateral edges, and a cut edge interconnecting the lateral edges such that each second heat dissipating fin has a smaller area than each first heat dissipating fin. Thus, the flow field resistance of the heat dissipating device can be reduced to increase the amount of airflow through the heat dissipating device for enhancing the heat dissipating efficiency.
