Heat dissipation device with fan holder

Abstract

A heat dissipation device includes a heat sink, a fan mounted on the heat sink and a fan holder mounting the fan on the heat sink. The fan holder includes a fan guard resting on the fan, a first clip and a second clip pivotably attached to the fan guard and engaged with the heat sink. The first clip includes an actuating member pivotably connecting to the fan guard and a buckling member pivotably connecting to the actuating member. The buckling member has a clasp engaging the heat sink at a locked position. The buckling member moves with a pivotal movement of the actuating member relative to the fan guard to leave the locked position and reach an unlocked position.

Description

BACKGROUND[0001]1. Technical Field[0002]The disclosure relates to a heat dissipation device and, more particularly, to a heat dissipation device having a fan holder for securing a fan onto a heat sink of the heat dissipation device, wherein the fan holder can be easily assembled to and disassembled from the heat sink to mount / dismount the fan to / from the heat sink.[0003]2. Description of Related Art[0004]It is well known that during operation computer electronic devices such as central processing units (CPUs) can generate large amounts of heat. The heat must be quickly removed from the electronic device to prevent it from becoming unstable or being damaged. Typically, a heat sink is attached to an outer surface of the electronic device to absorb heat from the electronic device, and the heat absorbed by the heat sink is then dissipated to ambient air.[0005]Generally, in order to improve heat dissipation efficiency of a heat sink, a fan is desired to direct airflow onto the heat sink....

AI Technical Summary

Benefits of technology

[0005]Generally, in order to improve heat dissipation efficiency of a heat sink, a fan is desired to direct airflow onto the heat sink. It is generally to fix the fan onto the heat sink with screws. Furthermore, it is necessary to disassemble the fan from the heat sink when dust particles accumulate in the fan and the heat sink, whereby the fan and the heat sink can be cleaned. Otherwise, heat dissipation efficiency of the heat sink will be decreased and a lifespan of the fan will be shortened. After cleaning of the fan and heat sink, it is required to assemble the fan to the heat sink again. Both the disassembling and assembling require rotating the screws by using a screwdriver. Such an unscrewing and screwing operation is laborious and time consuming. In addition, it is possible that the screws or screwdriver may drop to cause damages to computer components in the process of assembling and disassembling.
