Definitions

  • the present invention relates to a heat-dissipating fan and, more particularly, to a heat-dissipating fan allowing easy assembly of a power line.
  • Heat-dissipating fans generally include a power line for connection with an external power source for driving the heat-dissipating fans.
  • the position for fixing the power line must be carefully arranged to avoid the power line from being loosened or being entangled in an impeller of the heat-dissipating fan.
  • the power line in most of the currently available heat-dissipating fans winds in a complex manner and, thus, causes inconvenience to assembly.
  • FIG 1 shows a conventional heat-dissipating fan 70 including a wire-positioning mechanism 71.
  • the wire-positioning mechanism 71 includes a bottom 711, two support portions 712, and two stop portions 713.
  • a power line 72 winds through the bottom 711, the support portions 712, and the stop portions 713.
  • the power line 72 can be reliably positioned by the wire-positioning mechanism 71, an end of the power line 72 must be extended from under the heat-dissipating fan 70 to the outside and then wind through the bottom 711, the support portions 712, and the stop portions 713 in sequence, increasing difficulties to assembly of the power line 72.
  • the wire-positioning mechanism 71 is complex and, thus, increases the overall costs of the heat-dissipating fan 70.
  • FIGS. 2 and 3 show another conventional heat-dissipating fan 8 including a housing 81, a stator seat 82, an impeller 83, and a lid 84.
  • the housing 81 includes a compartment 811 and a channel 812 in communication with the compartment 811.
  • the stator seat 82 is mounted in the compartment 811 and has a connection port 821 connected to a power line 822.
  • the impeller 83 is rotatably coupled to the stator seat 82 and has a permanent magnet 831.
  • the lid 84 includes a tab 841 that extends into the channel 812 when the lid 84 is coupled to the housing 81.
  • an end of the power line 822 winds through the channel 812 to the outside for connection with an external power source.
  • the tab 841 presses against and, thus, positions the power line 822.
  • the connection port 821 does not face the channel 812 and is spaced from the channel 812 by a distance. After the power line 822 is connected to the connection port 821, the power line 822 must wind through the distance in the compartment 811 before the power line 822 exits the housing 81 via the channel 812, increasing difficulties in winding the power line 822 and leading to inconvenience to assembly.
  • the power line 822 is liable to be entangled into the impeller 83 during operation of the heat-dissipating fan 80, for the power line 822 winds through a considerable distance in the compartment 811 of the housing 81.
  • the connection port 821 of the stator seat 82 is located below the permanent magnet 831 of the impeller 83, such that a spacing D must be preserved between a bottom edge of the permanent magnet 831 and the stator seat 82 for receiving the power line 822 and the connection port 821, such as a welding point, for the purposes of assuring smooth rotation of the impeller 83.
  • the spacing D causes a limitation to the reduction in the overall axial height of the heat-dissipating fan 80. As a result, it is difficult to achieve light, compact design of the heat-dissipating fan 80.
  • FIG 4 shows a further conventional heat-dissipating fan 90 including a base 91 having a peripheral wall.
  • a block 92 is mounted in a wire-guiding channel 911 formed in a corner of the peripheral wall.
  • a power line 93 of the heat-dissipating fan 90 winds through a distance in the base 91 to a position aligned with the wire-guiding channel 911 and then exits the base 91 via the wire-guiding channel 911 for connection with an external power source.
  • the block 92 presses against and, thus, positions the power line 93.
  • the connection port of the stator of the heat-dissipating fan 90 for driving an impeller 94 does not face the wire-guiding channel 911.
  • the power line 93 still has to winds through the distance in the base 91 before the power line 93 reaches the wire-guiding channel 911, increasing difficulties in winding the power line 93 and leading to inconvenience to assembly.
  • An objective of the present invention is to provide a heat-dissipating fan avoiding difficulties and inconvenience in the assembly of the power line.
  • Another objective of the present invention is to provide a heat-dissipating fan with a reduced axial height.

  • the shaft is coupled to the shaft seat, and the permanent magnet faces the coil unit.
  • the connection port is located on a reference line passing through the shaft seat and the wire-guiding slot. A distance between the connection port and the wire-guiding slot is shortened to enhance assembling convenience of the power line.
  • connection port of the base is located outside of a rotational area of the permanent magnet, and the connection port is intermediate an outer periphery of the permanent magnet and an inner peripheral face of the peripheral wall of the housing.
  • a spacing between the permanent magnet and the base can be shortened, for the connection port and the power line are not located in the spacing.

  • the housing 10 further includes a bottom wall 111 formed inside the peripheral wall 11 and defining the compartment 12.
  • the base 20 is mounted in the compartment 12 and preferably coupled to the shaft seat 13.
  • the base 20 abuts the bottom wall 111, and the catches 112 engage with an outer periphery of the base 20 to fix the base 20 in place.

  • the coil unit 21 is formed on a face of the base 20 by layout or other suitable provisions to reduce an axial height of the base 20.
  • the connection port 22 includes one or more connections.
  • the connection port 22 faces the wire-guiding slot 16 of the housing 10.
  • the connection port 22 is located on the reference line L. Namely, the shaft seat 13, the wire-guiding slot 16, and the connection port 22 are located on the reference line L, shortening the distance between the connection port 22 and the wire-guiding slot 16.
  • An end of the power line 30 is connected to the connection port 22 of the base 20.

  • connection port 22 faces the wire-guiding slot 16 of the housing 10 and since the connection port 22 is located on the reference line L, the connection port 22 is close to the wire-guiding slot 16. Namely, the distance between the connection port 22 and the wire-guiding slot 16 can be shortened. After the end of the power line 30 is connected to the connection port 22, the other end of the power line 30 can extend beyond the housing 10 directly through the wire-guiding slot 16 without the need of winding the power line 30 inside the housing 10.

  • the connection port 22 is located outside of a rotational area of the permanent magnet 412. Specifically, the connection port 22 is intermediate an outer periphery of the permanent magnet 412 and an inner peripheral face of the peripheral wall 11 of the housing 10.
  • connection port 22 faces the wire-guiding slot 16 of the housing 10 and since the connection port 22 is located on the reference line L, the assembling convenience of the power line 30 is enhanced. Furthermore, the power line 30 is prevented from being entangled into the impeller 40 during operation of the heat-dissipating fan 2. Furthermore, a spacing D ( FIG. 9 ) between the permanent magnet 412 of the impeller 40 and the base 20a can be shortened, for the connection port 22 and the power line 30 are not located in the spacing D. Thus, the overall axial height of the heat-dissipating fan 2 along the axis can be reduced, allowing light, compact design of the heat-dissipating fan 2.
  • FIGS. 10 and 11 show a heat-dissipating fan 3 of an embodiment according to the preferred teachings of the present invention.
  • the heat-dissipating fan 3 includes a housing 10, a base 20b, a power line 30, and an impeller 40.

  • the extension 23 and the connection port 22 are located on the reference line L.
  • connection port 22 faces the wire-guiding slot 16 of the housing 10 and since the connection port 22 is located on the reference line L, the assembling convenience of the power line 30 is enhanced.

Furthermore, by providing the extension 23 of the base 20b, the connection port 22 is located outside of the rotational area of the permanent magnet 412 of the impeller 40. Further, the connection port 22 is closer to the wire-guiding slot 16, so that straight insertion of the other end of the power line 30 through the wire-guiding slot 16 is easier, further enhancing the assembling convenience of the power line 30.
  • FIGS. 12 and 13 show a heat-dissipating fan 4 of a third example.

Furthermore, the connection port 22 is adjacent to the wire-guiding slot 16 due to provision of the drive circuit board 25, further enhancing the assembling convenience of the power line 30. Furthermore, the electric elements on the drive circuit board 25 are located outside of the rotational area of the permanent magnet 412 of the impeller 40, so that the power line 30 is far away from the rotational area of the impeller 40. Further, the connection port 22 is closer to the wire-guiding slot 16, so that straight insertion of the other end of the power line 30 through the wire-guiding slot 16 is easier, further enhancing the assembling convenience of the power line 30.
