Description
- 1. Technical Field
- The present invention relates to an air-cooled heat sink and, in particular, to a heat sink having an integrated heat sink fin and fan blade.
- 2. Related Art
- 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.
- 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.
- 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. Therefore, the inventor is motivated to provide a thin-type heat sink by combining the heat sink fan and the heat sink member while required heat dissipation efficiency is also achieved.
- In view of the foregoing, the inventor made various studies to improve the above-mentioned problems efficiently, on the basis of which the present invention is accomplished.
- It is an objective of the present invention to provide a heat sink having an integrated heat sink fin and fan blade, so as to simplify a structure of the heat sink and to prolong a lifespan of the heat sink.
- Accordingly, the present invention provides a heat sink having a heat sink fin that is also a fan blade, the heat sink comprising:
- a base including a heat conduction plate and a support pillar disposed on the heat conduction plate;
- a heat sink base including a support plate and a plurality of heat sink fins disposed on the support plate, the support plate being correspondingly disposed over the heat conduction plate, a gap being formed between the support plate and the heat conduction plate;
- a bearing disposed between the support pillar and the heat sink base;
- a rotor disposed on the heat sink base; and
- a stator disposed corresponding to the rotor and fixed on the base, an air gap being formed between the rotor and the stator, wherein the heat sink base is rotatable with respect to the support pillar by an electromagnetic effect between the rotor and the stator.
- The support pillar is integrally formed with the heat conduction plate and extends from a center of the heat conduction plate.
- The heat conduction plate includes at least one annular trench on one side of the heat conduction plate facing the support plate, and the support plate includes an annular plate, disposed corresponding to the annular trench, on one side of the support plate facing the heat conduction plate. The annular plate is inserted in the annular trench and is spaced above a bottom of the annular trench, so as to achieve the tightness between the base and the heat sink base to prevent objects or dust from falling into the gap and thereby maintain good operation and heat dissipation efficiency.
- The heat sink fins are circularly disposed around the support pillar, the heat sink fins form an accommodation room, the rotor is disposed in the accommodation room, and the stator is disposed corresponding to the rotor and fixed on the support pillar.
- The heat sink base extends from the heat conduction plate to form a hollow tube in the accommodation room, and the bearing is closely disposed between an inner wall surface of the hollow tube and an outer circumferential surface of the support pillar.
- The rotor is a permanent magnetic set, the stator is a coil set, the rotor disposed in the accommodation room is at one side thereof away from the support plate, and the stator is fixed at one side of the support pillar away from the heat conduction plate, so as to prevent heat of heat-generating elements from being transferred to the rotor or the stator to reduce a lifespan of the rotor or the stator.
- The bearing includes an inner ring, an outer ring, and a plurality of rollers rollably disposed between the inner ring and the outer ring, the inner ring is fixed on the support pillar of the base, the outer ring is fixed on the heat sink base, and the inner ring is rotatable with respect to the outer ring to enable the heat sink base to be rotatable on the base.
- The heat sink fins are spaced from one another and arranged in a whirlpool shape.
- The base is a vapor chamber, and the vapor chamber includes a planar plate which forms the heat conduction plate and a straight tube which forms the support pillar.
- The heat sink base further includes a cap engaged with the support pillar, and the stator is disposed on an outer circumferential surface of the cap.
- The cap encloses the bearing.
- The rotor is disposed on one side of the support plate facing the heat conduction plate, and the stator is disposed corresponding to the rotor and fixed on one side of the heat conduction plate facing the support plate.
- The support plate is disposed over the support pillar and covers the same.
- Compared with the conventional techniques, the heat sink base of the present invention is movably connected on the base by means of the bearing. In addition, the rotor and the stator are correspondingly disposed on the heat sink base and the base, respectively. After the stator is electrically connected, an electromagnetic field is generated to enable interaction between the stator and the rotor, thereby rotating the heat sink base with respect to the base. The heat sink base rotates with respect to the support pillar to generate forced airflow. Compared with the conventional heat sink, the heat sink of the present invention has a simple structure, whereby a rotational center of a fan is omitted, and the heat sink base is connected on the support pillar by means of the bearing. By means of the support pillar, the present invention can prevent abrasion that tends to occur on a bearing of a conventional fan, and thereby a lifespan of the heat sink is prolonged, and the utility of the present invention is enhanced.

Aheat sink 1, having an integrated heat sink fin and fan blade, comprises abase 10, aheat sink base 20, abearing 30, arotor 40, and astator 50. Theheat sink base 20 is connected on thebase 10. Thebearing 30 is disposed between thebase 10 and theheat sink base 20. Theheat sink base 20 is rotatable with respect to thebase 10 by means of thebearing 30. Therotor 40 and thestator 50 are disposed corresponding to each other. Therotor 40 and thestator 50 are disposed on theheat sink base 20 or thebase 10 respectively or vice versa. - The
base 10 includes aheat conduction plate 11 and asupport pillar 12 disposed on theheat conduction plate 11. Theheat sink base 20 includes asupport plate 21 and a plurality of heat sink fins 22 disposed on thesupport plate 21. Thesupport plate 21 is correspondingly disposed over theheat conduction plate 11, and agap 200 is formed between thesupport plate 21 and theheat conduction plate 11. The heat sink fins 22 are circularly disposed around thesupport pillar 12. Thebearing 30 is disposed between thesupport pillar 12 and theheat sink base 20. To be specific, thegap 200 is formed between the base 10 and theheat sink base 20 by disposing thebearing 30. According to the present embodiment, thebearing 30 includes aninner ring 31, anouter ring 32, and a plurality ofrollers 33 rollably disposed between theinner ring 31 and theouter ring 32. Therollers 33 are, for example, rolling balls or rolling pillars. Theinner ring 31 is fixed on thesupport pillar 12 of thebase 10, theouter ring 32 is fixed on theheat sink base 20, and theinner ring 31 is rotatable with respect to theouter ring 32 to enable theheat sink base 20 to be rotatable on thebase 10. - Moreover, the
rotor 40 is disposed on theheat sink base 20, thestator 50 is disposed corresponding to therotor 40 and fixed on thebase 10, and anair gap 500 is formed between therotor 40 and thestator 50. - The
support pillar 12 is integrally formed with theheat conduction plate 11 and extends from a center of theheat conduction plate 11. Theheat conduction plate 11 includes at least oneannular trench 111 on one side of theheat conduction plate 11 facing thesupport plate 21, and thesupport plate 21 includes anannular plate 211, disposed corresponding to the annular trench, on one side of thesupport plate 21 facing theheat conduction plate 11. Accordingly, when theheat sink base 20 is connected to thebase 10, theannular plate 211 inserted in theannular trench 111 is spaced above a bottom of theannular trench 111. By this arrangement, the tightness between the base 10 and theheat sink base 20 can be achieved to prevent objects or dust from falling into thegap 200 between the base 10 and theheat sink base 20, thereby maintaining good operation and heat dissipation efficiency of theheat sink 1. - According to one embodiment of the present invention, the
heat sink fins 22 are spaced from one another and arranged in a whirlpool shape. Theheat sink fins 22 form anaccommodation room 220, therotor 40 is disposed in theaccommodation room 220, and thestator 50 is disposed corresponding to therotor 40 and fixed on thesupport pillar 12. - The arrangement of the
bearing 30 is detailed as follows. Theheat sink base 20 extends from theheat conduction plate 11 to form ahollow tube 23 in theaccommodation room 220, and thebearing 30 is closely disposed between an inner wall surface of thehollow tube 23 and an outer circumferential surface of thesupport pillar 12. In the present embodiment, thebearing 30 is disposed at one side of thesupport pillar 12 nearer to theheat conduction plate 11. - According to the present embodiment, the
rotor 40 is a permanent magnetic set, thestator 50 is a coil set, therotor 40 disposed in theaccommodation room 220 is at one side thereof away from thesupport plate 21, and thestator 50 is fixed at one side of thesupport pillar 12 away from theheat conduction plate 11. - The
heat sink 1 of the present invention is used to dissipate heat of a heat-generating element. In practical applications, theheat conduction plate 11 of theheat sink 1 is attached on a heat-generating element (not illustrated), and an external power source is connected to thestator 50. After thestator 50 is electrically connected, an electromagnetic field is generated to enable interaction between thestator 50 and therotor 40, thereby rotating theheat sink base 20 with respect to thebase 10. That is to say, theheat sink base 20 rotates with respect to thesupport pillar 12 by the electromagnetic effect between therotor 40 and thestator 50, theheat sink base 20 rotates with respect to thesupport pillar 12 by means of thebearing 30, and accordingly theheat sink fins 22 of theheat sink base 20 are driven to rotate to generate forced airflow. - The reason why the
stator 50 is fixed at one side of thesupport pillar 12 away from theheat conduction plate 11 is that this arrangement can prevent the heat of the heat-generating element from being transferred to therotor 40 or thestator 50. By this arrangement, the heat of the heat-generating element exerts the least influence on the stator 50 (the coil set), thereby prolonging a lifespan of thestator 50. - Please refer to
