Abstract

A fan device mounted on the top opening of a cylindrical cooler. Fan comprises a ring plate member, a seat, a plurality of blades, and a plurality of ribs interconnected between the ring plate member and the seat. Blades are rotationally mounted on seat. The bottom of fan is abutted on the inner bottom surface of cooler. Wind generated by the activation of blades is directed toward cooler. As such, the heat transferred from a heat source may be effectively radiated to the outside.

Description

    FIELD OF THE INVENTION
  • [0001]
    The present invention relates to fans and more particularly to a fan used in conjunction with cooler of central processing unit (CPU).
  • BACKGROUND OF THE INVENTION
  • [0002]
    It is known that the temperature of CPU is high during operation. As such, heat ventilation is very important as to the normal operation of CPU. A number of techniques and devices have been proposed and commercially available for improving the heat ventilation of CPU by manufacturers. For example, a heat ventilation device called “Power Cooler” 12 is mounted on the K7 processor manufactured by AMD a U.S. based corporation as shown in FIGS. 1 to 3. Such cooler 12 is a hollow cylinder having a plurality of fins parallel longitudinally disposed on the outer surface. Further, a passage is formed between two adjacent fins for providing a heat ventilation path from the fan to the outside. The fan mounted on cooler 12 in FIG. 1 is different from the fan mounted on cooler 12 in FIG. 2. But both fans serve to radiate superfluous heat from CPU through the cooler 12.
  • [0003]
    But these two types of fans are unsatisfactory for the purpose for which the invention is concerned for the following reasons:
  • [0004]
    1. As to the heat ventilation arrangement shown in FIG. 1, fan 10 is secured to the inside of cooler 12 by a plurality of screws 11. However, the previous design suffered from several disadvantages. For example, seat 13 is very close to the bottom 16 of cooler 12 (FIG. 3). As such, the temperature at the bottom 16 is undesirably increased because the bottom 16 is adjacent the hot CPU plus the heat generated by the driving elements (e.g., coils, magnets, and etc.) accumulated therein. In brief, the provision of fan 10 has adversely affected the heat ventilation capability of cooler 12. Moreover, as shown in FIG. 3, it is difficult for a person to use a tool to perform a fastening/unfastening of seat 13 inside the fan 10 due to the blocking of blades 14. One may increase the spacing between two adjacent blades 14. But it inevitably sacrifices the heat ventilation efficiency due to the reduction of the total area of blades 14. In fact, it is not applicable. Also, as shown in FIG. 3, a power cord 15 under blades 14 is adjacent the hot bottom 16. As such, the shield of power cord 15 may be damaged by the high temperature. This may adversely affect the normal operation of fan 10.
  • [0005]
    2. As to the other heat ventilation arrangement shown in FIG. 2, seat 23 is fixed to frame 22 under the ring plate member 21. This solves the problem (i.e., difficult for fastening/unfastening of fan 10 in cooler 12) experienced in the FIG. 1 prior art. However, it still suffered from several disadvantages. For example, the heat ventilation path of blades 24 is blocked by frame 22, thus lowers the heat ventilation efficiency of the heat ventilation arrangement. Further, seat 23 is very close to the bottom of cooler 20. As such, the temperature at the bottom of cooler 20 is still undesirably increased because the bottom of cooler 20 is adjacent the hot CPU. This drawback is the same as the heat ventilation arrangement in FIG. 1. Furthermore, the ring plate member 21 is glued to the top opening of cooler 20. This is a poor fastening design. In a worse condition, cooler 20 may become disengaged from fan due to the melting of the adhesive.
  • SUMMARY OF THE INVENTION
  • [0006]
    It is an object of the present invention to provide a fan device mounted on the top opening of a cylindrical cooler. Fan comprises a ring plate member, a seat, a plurality of blades, and a plurality of ribs interconnected between the ring plate member and the seat. Blades are rotationally mounted on seat. The bottom of fan is abutted on the inner bottom surface of cooler. Wind generated by the activation of blades is directed toward cooler. As such, the heat transferred from a heat source may be radiated to the outside.
  • [0007]
    It is another object of the present invention to provide a fan device wherein the heat ventilation path of blades is not blocked, thereby improving the heat ventilation efficiency of the fan device.
  • [0008]
    It is still another object of the present invention to provide a fan device wherein the power cord is far from the heat source, thus lowering the possibility of being damaged by the heat source.
  • [0009]
    It is a further object of the present invention to provide an fan device wherein a plurality of fasteners are driven through the ring plate member to secure the fan to the cooler.
  • [0010]
    The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • [0018]
    Referring to FIGS. 4 to 7, there is shown a heat ventilation device constructed in accordance with the invention comprising a cooler 30 and a fan 40 secured to the top opening 30 a of cooler 30. Cooler 30 is a hollow cylindrical member having a plurality of fins 31 parallel longitudinally disposed on the outer surface. Further, a passage 31 a is formed between two adjacent fins 31 for providing a heat ventilation path from the fan 40 to the outside. A short cylindrical bar 33 is projected on the underside 32 of cooler 30. Bar 33 is in contact with a heat source (e.g., CPU not shown). Thus heat generated by CPU may be transferred to cooler 30 through bar 33. Fan 40 comprises a ring plate member 41, a seat 43, a plurality of blades 44, and a plurality of ribs 42 interconnected between ring plate member 41 and seat 43. Blades 44 are rotationally mounted on seat 43. The bottom 44 a of fan 40 is abutted on the inner bottom surface of cooler 30. Wind generated by the activation of blades 44 is blowing toward cooler 30 and fins 31. As such, the heat transferred from CPU may be radiated to the outside through passages 31 a and fins 31.
  • [0019]
    A plurality of pairs of parallel inserts 461 and 462 are provided at the underside of ring plate member 41. A connecting member 463 is coupled between inserts 461 and 462. A threaded hole 47 is formed at ring plate member 41 between the pair of inserts 461 and 362. As shown in FIG. 7 specifically, inserts 461, 462 are inserted into two passages 31 a respectively, while connecting member 463 is urged against the inner rear sides of fins 31. Thus ring plate member 41 is engaged with cooler 30. A screw 50 is driven through threaded hole 47 to secure to a passage 31 b. As such, fan 40 is secured to cooler 30. Further, a plurality of elongate arcuate ventilation openings 411 are equally spaced apart on ring plate member 41 for enhancing the heat ventilation of the invention. Furthermore as shown in FIG. 4, a hole 412 is formed on ring plate member 41 for allowing power cord 45 to pass through. The power cord 45 is far from the bottom of cooler 30 (i.e., adjacent CPU) for lowering the possibility of being damaged by the high temperature CPU.
  • [0020]
    While the invention has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
