Abstract
A suspension type heat-dissipation fan includes a frame rotatably supporting an air impeller therein. The frame has an air outlet and is formed with an inner rim defining an opening aligned with the air impeller. In addition, a ring is attached to the rim of the frame and has an inner periphery defining an air inlet of a size smaller than the diameter of the air impeller. This inventive fan increases the pressure of airflow into the air inlet, while enabling the air impeller to be placed into the frame through the opening before assembling the ring to the rim.
Description
- 1. Field of the Invention
- The present invention relates to a fan and, more particularly, to a suspension type heat-dissipation fan which has an air inlet of a reduced size in order to increase the pressure of airflow into the air inlet.
- 2. Description of Related Art
- Many types of fans are known. FIG. 8 shows a suspension type heat-dissipation fan that includes a
frame 80 defining anupper air inlet 81. Theframe 80 further has a plurality of downwardly-extendingstruts 82 supporting alower hub 83, which is provided with asleeve 84 for rotatably receiving aspindle 86 of anair impeller 85. When being turned, theair impeller 85 blows on aheat sink 87 to facilitate dissipating heat derived from a heat source. - However, it has been found that the pressure of airflow into the
air inlet 81 is relative low, since theair impeller 85 is placed into theframe 80 just through theair inlet 81 and thus theinlet 81 must has a size larger than the diameter of theimpeller 85. - FIG. 9 shows a conventional blower fan that includes a
housing 90 for receiving and rotatably supporting anair impeller 91. Thehousing 90 is covered with atop plate 92 which defines anair inlet 93 aligned with theair impeller 91. When being turned, theimpeller 91 draws air through theair inlet 93 and blows out a current of air from anair outlet 94, so as to blow on a heat source. - In this conventional fan, the
air inlet 93 may have a size smaller than the diameter of theair impeller 91 and so the pressure of airflow into theair inlet 81 is increased, but theair impeller 91 can not be placed into thehousing 90 through theair inlet 93. This makes the fan complex in structure and difficult to be manufactured. - The object of the present invention is to provide a suspension type heat-dissipation fan which can increase the pressure of airflow into an air inlet in a simplified manner.
- The present invention provides a suspension type heat-dissipation fan comprising a frame rotatably supporting an air impeller therein. The frame has an air outlet and is formed with an inner rim defining an opening aligned with the air impeller. A ring is attached to the rim of the frame and has an inner periphery defining an air inlet of a size smaller than the maximum diameter of said air impeller, so as to increase the pressure of airflow into the air inlet.
- Other objects, advantages and novel features of this invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
- FIG. 1 is an exploded perspective view of a preferred embodiment of a suspension type heat-dissipation fan in accordance with the present invention;
- FIG. 2 is a top view of the suspension type heat-dissipation fan of FIG. 1;
- FIG. 3 is a cross-sectional view taken along lines3-3 in FIG. 2;
- FIG. 4 is an enlarged cross-sectional view taken from
part 4 in FIG. 3; - FIG. 5 is an exploded perspective view of an alternative embodiment of the inventive fan;
- FIG. 6 is a top view of the suspension type heat-dissipation fan of FIG. 5;
- FIG. 7 is a cross-sectional view taken along lines7-7 in FIG. 6;
- FIG. 8 is an exploded perspective view of a conventional suspension type heat-dissipation fan; and
- FIG. 9 is an exploded perspective view of a conventional blower fan.
- Referring to FIG. 1, there is shown a preferred embodiment of a suspension type heat-dissipation fan in accordance with the present invention. The inventive fan includes a
frame 1 rotatably supporting anair impeller 12 therein. Theframe 1 has anair outlet 14, and is formed with aninner rim 13 that defines anupper opening 11 aligned with theair impeller 12. - In the inventive fan, a
ring 2 is attached to therim 13 of theframe 1 and has an inner periphery that defines an air inlet of a predetermined size smaller than the diameter of theair impeller 12, as best shown in FIG. 2. The air inlet of such a size increases the pressure of air flow in the inlet when theair impeller 12 is in rotation. - Referring to FIGS. 2 and 3, the
ring 2 has aninclined end surface 21, preferably configured as a curved surface, that slopes towards theair impeller 12 from its radially outer portion to its radially inner portion for the purpose of leading air into the air inlet. - Referring to FIG. 4, the
ring 2 can be attached to theinner rim 13 of theframe 1 in many ways. For example, thering 2 may have an outer periphery defining anannular groove 22 into which theinner rim 13 can be snapped, thus attaching thering 2 securely to therim 13 and hence to theframe 1. - Referring to FIG. 5, an alternative embodiment of the inventive fan is shown. Now the fan includes a
frame 1 adapted to be installed on ahollow base 4. - The
hollow base 4, made of a metal material having excellent thermal conductivity, can be connected to theframe 1 by means of a plurality ofscrews 41. Thebase 4 has anupright enclosure 42 defining a plurality ofvent ports 43 therein. As illustrated, theenclosure 42 preferably consists of four sidewalls with thevent ports 43 defined in more than one sidewall of theenclosure 42. - The
frame 1 is also provided for rotatably supporting anair impeller 12 therein and is formed with anair outlet 13. However, theframe 1 here has aninner rim 13 stepped so as to define acountersunk opening 11, which has an enlarged top part suitable for receiving aring 3. - The
ring 3 is attached to thestepper rim 13 of theframe 1. Again, thering 3 has an inner periphery that defines an air inlet of a size smaller than the maximum diameter of theair impeller 12, as best shown in FIG. 6. - Referring to FIGS. 6 and 7, the
ring 3 is situated in the enlarged top part of thecountersunk opening 11, and is attached to the steppedinner rim 13 by means of adhesive. Preferably, thering 3 has a uniform thickness and combined with therim 13 to form a common top surface of theframe 1, as shown in FIG. 7, thereby providing the inventive fan with an attractive appearance. - From the foregoing, it is apparent that this invention has the advantage of increasing the pressure of airflow into the air inlet, as well as allowing the
air impeller 12 to be placed into theframe 1 through theopening 11 before assembling thering rim 13. - While the principles of this invention have been disclosed in connection with specific embodiments, it should be understood by those skilled in the art that these descriptions are not intended to limit the scope of the invention, and that any modification and variation without departing the spirit of the invention is intended to be covered by the scope of this invention defined only by the appended claims.
