Benefits of technology

The present invention provides a heat sink with an integrated heat sink fin and fan blade to simplify the structure and prolong the lifespan of the heat sink. The heat conduction plate and support plate have annular trenches and plates that fit tightly together to prevent objects or dust from falling into the gap and maintain good operation and heat dissipation efficiency. The rotor and stator are separate to prevent heat transfer and reduce lifespan. The heat sink base is movably connected on the base by a bearing and rotates with respect to the support pillar to generate forced airflow. Compared to conventional heat sinks, the present invention has a simpler structure, avoids abrasion on the bearing, and enhances the lifespan of the heat sink.

Problems solved by technology

However, the conventional heat sink fan generally has a rotational center, and the rotational center is stuck from time to time due to the carbide generated by frictions on bearing oil and rubber at high temperature, thereby resulting in that the heat sink fan is unable to rotate, and the heat sink member cannot dissipate heat efficiently as expected.
Moreover, along with the development of compact, light and thin electronic apparatuses, an inner space of the computer housing is getting small, so the heat sink apparatuses have to be made as thin as possible.

Abstract

A heat sink includes a base, a heat sink base, a bearing, a rotor, and a stator. The base includes a heat conduction plate and a support pillar disposed on the heat conduction plate. The heat sink base includes a support plate and heat sink fins disposed on the support plate. The support plate is correspondingly disposed over the heat conduction plate, and a gap is formed between the support plate and the heat conduction plate. A bearing is disposed between the support pillar and the heat sink base. A rotor is disposed on the heat sink base, the stator is disposed corresponding to the rotor and fixed on the base. The heat sink base rotates with respect to the support pillar by an electromagnetic effect between the rotor and the stator.

Related Art[0004]As technical advancements increase the speed of computer CPUs, the computer and peripheral electrical components are generally equipped with heat sinks, so as to dissipate heat generated during operations of the electrical components.[0005]A conventional heat sink apparatus mainly includes a heat sink fan and a heat sink member. The heat sink member includes a plurality of heat sink fins attached on heat-generating elements. Furthermore, the heat sink fan is disposed on the heat sink member, and fan blades generate airflow which flows to the heat sink fins, so as to quickly dissipate the heat transferred to the heat sink fins from the electrical components.[0006]However, the conventional heat sink fan generally has a rotational center, and the rotational center is stuck from time...
