Abstract
Description
- 1. Technical Field
- The disclosure relates generally to a heat dissipation device for removing heat from an electronic component mounted on a periphery card, and particularly to a heat dissipation device comprising a blower facing a base of a heat sink in contact with the electronic component to define an airflow passage between the base of the heat sink and the blower, wherein airflow can pass through the airflow passage.
- 2. Description of Related Art
- 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.
- Thus, a heat dissipation device which can quickly remove the heat from the electronic device is needed. Such a heat dissipation device is particularly necessary for a periphery card of a computer, for example, a video graphic array (VGA) card. A periphery card is usually crowded with other periphery cards whereby only a limited space is available for an airflow to flow through a heat sink thereof. The heat dissipation device usually includes the heat sink and a blower mounted to the heat sink. Since the periphery card has a limited space, accordingly, the heat sink is designed to have a flat-shaped base and fins with a limited height. The blower is desired to guide airflow to pass through the fins of the heat sink from one side to an opposite side thereof.
- However, the blower usually includes a fan frame and a cover covering and mounted to the fan frame. Airflow produced by the blower only flows along a passage cooperatively defined by the fan frame and the cover of the blower. That is to say, when the blower is mounted to the base of the heat sink, the airflow produced by the blower fails to directly blow towards the base of the heat sink under the blower, the heat accumulated at the base of the heat sink under the blower fails to be quickly dissipated.
- What is needed, therefore, is a heat dissipation device which has a blower to directly blow towards the base of the heat sink.
- Other advantages and novel features of the disclosure will become more apparent from the following detailed description of an embodiment/embodiments when taken in conjunction with the accompanying drawings.
-
FIG. 1 is an exploded, isometric view of a heat dissipation device in accordance with an embodiment of the disclosure. -
FIG. 2 is an assembled view of the heat dissipation device ofFIG. 1 . -
FIG. 3 is a similar view ofFIG. 1 , with arrows showing paths of airflow entering and leaving the heat dissipation device. - Referring to
FIGS. 1-3 , a heat dissipation device in accordance with an embodiment of the disclosure is shown. The heat dissipation device is mounted to a heat-generating electronic element (not shown) to dissipate heat from the heat-generating electronic element. Particularly, the heat-generating electronic element is a graphic processing unit (GPU) mounted on a periphery card of a computer, for example, a video graphic array (VGA) card. The heat dissipation device comprises aheat sink 10, ablower 20 and a guidingplate 30. - The

Thebase 12 comprises three portions: a first portion located in a middle of thebase 12, a second portion extending forth from an end of the first portion and a third portion extending rearwards from an opposite end of the first portion. The first portion of thebase 12 has a semicircular shape with a size corresponding to that of theblower 20, for supporting theblower 20 thereon. A semicircularfirst airflow inlet 120 is defined in the first portion of thebase 12. A pair ofmounting poles 16 is formed at two opposite ends of a front side of the first portion of thebase 12, and anothermounting pole 16 is formed on a middle portion of a top surface of the third portion of thebase 12, adjacent to the rear side of the first portion of thebase 12. Eachmounting pole 16 defines amounting hole 160 therein. A plurality offins 14 are integrally formed on a top surface of the second portion of thebase 12. Thefins 14 have a gradually increased lengths from a left lateral side to a right lateral side of the second portion of thebase 12, wherein thefins 14 are located at a position and occupy a size corresponding to those of an outlet of theblower 20. Eachfin 14 defines a recessed edge at a top thereof and all recessed edges of all thefins 14 cooperatively define arecessed slot 140 in a top of thefins 14. Thefront side 142 of the second portion of thebase 12 under thefins 14 is inclined downwardly in respect to the first portion of thebase 12, wherein airflow from the outlet of theblower 20 blowing towards channels defined between thefins 14 can be guided to downwardly blow other heat-generating electronic elements mounted on the periphery card and adjacent to the front side of thebase 12 of theheat sink 10. - The
blower 20 comprises aframe 22 and animpeller 24. Theframe 22 comprises apanel plate 220 and alateral sidewall 222 downwardly and vertically extending from an edge side of thepanel plate 220. Theimpeller 24 is rotatably secured to an inner surface of thepanel plate 220 of theframe 22. A plurality ofsecond airflow inlets 2200 are defined in thepanel plate 220, corresponding to thefirst airflow inlet 120 of thebase 12 of theheat sink 10. Threefixing portions 224 horizontal and outwardly extend from thelateral sidewall 222 and are evenly located along a periphery of theframe 22 of theblower 20, corresponding to themounting poles 16 of thebase 12 of theheat sink 10. Eachfixing portion 224 defines a throughhole 2240 therein, in alignment with themounting hole 160 of acorresponding mounting pole 16 of thebase 12 of theheat sink 10, for receiving afastener 90 extending therethrough. Thefasteners 90 extend through the throughholes 2240 of thefixing portions 224 of theframe 22 of theblower 20 and screw into themounting holes 160 of themounting poles 16 to mount theframe 22 of theblower 20 on the first portion of thebase 12 of theheat sink 10, wherein thebase 12 of theheat sink 10 and theframe 22 of theblower 20 cooperatively define an airflow passage along a length direction of thebase 12 of theheat sink 10 and the outlet of theblower 20 faces the channels defined between thefins 14 of theheat sink 10. - The guiding
plate 30 has a size corresponding to that of a top surface of thefins 14 of theheat sink 10. The guidingplate 30 comprises amain body 32 and arecessed portion 34 extending outwardly and downwardly from a front side of themain body 32. The guidingplate 30 covers the top surface of thefins 14 with therecessed portion 34 being received in therecessed slot 140 to guide the airflow from the outlet of theblower 20 to downwardly flow to the channels defined between thefins 14 of theheat sink 10. - In operation, cooled airflow flows into the airflow passage between the
frame 22 of theblower 20 and thebase 12 of theheat sink 10 via the first andsecond airflow inlets base 12 of theheat sink 10, so heat generated by the heat-generating electronic element attached on a bottom of thebase 12 of theheat sink 10 can be effectively taken away. - By provision of the
frame 22 of theblower 20 engaging thebase 12 of theheat sink 10, theblower 20 not only can directly blow thebase 12 of theheat sink 10, but also saves a cover covering theframe 22 to define the airflow passage, whereby the cost of theblower 20 is decreased. In addition, thebase 12 of theheat sink 10 defines thefirst airflow inlet 120 therethrough, wherein the cooled airflow flowing into the airflow passage via thefirst airflow inlet 120 can cause air around the heat-generating electronic element to flow through the heat-generating electronic element; thus, the heat generated by the heat-generating electronic element can be taken away as quickly as possible. Heat accumulated at thebase 12 of theheat sink 10 under theblower 20 can be quickly dissipated. - It is to be understood, however, that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
