  • Patent number: 7075790
    Abstract: A heat dissipating device includes a heat sink (50) and two clips (10) for mounting the heat sink to a retention module (60) which surrounds an electronic component (65). The heat sink provides two shoulders (72). Each clip includes a strap (21) supported on one shoulder, a lever (40) having a cam pivotally connected to the strap, two legs (30) pivotally connected to opposite end portions of the strap, and two spring fingers (26) integrally extending from opposite ends of the strap. In assembly, the straps are downwardly pressed and the retention module push the legs to pivot away from the feet from original states toward forced states. When the legs arrive openings of the retention module the fingers urge the legs to enter the openings. The levers are then pivoted to push the straps to move upwardly to thereby cause the legs to firmly engage in the openings.

  • Patent number: 7054157
    Abstract: Measures are provided to prevent temperature rise caused by that heat generated from power elements, which is radiated inside a housing. In a housing comprising a radiating section and a cooling fan, a guide is provided on a part of the housing to be made longer a predetermined value than the radiating section. When the cooling fan performs forced cooling through the guide, gases heated by a substrate that generates much heat are prevented from flowing onto a substrate that generates comparatively less heat, to heat the substrate that generates comparatively less heat. Therefore, for example, the substrate that generates much heat is arranged in a position nearer to the cooling fan than the substrate that generates comparatively less heat. Alternatively, the substrate that generates much heat is arranged in a position nearer to the intake face than the substrate that generates comparatively less heat.

  • Patent number: 7044202
    Abstract: A cooler for electronic devices provides cool air to the inlet sides of the heat sink by using a radial blower with blades located around air outlets of the heat sink. This blower is driven by a brushless DC electric motor. The motor has an opening in the center allowing for the transfer of incoming air to the center of the heat sink. The rotors outer circumferential arrayed poles are rigidly secured to the frame of the radial blower. The stator of the motor is rigidly secured to the heat sink and has an opening in its center. The stator comprises circumferential arrayed coils on circuit board material. When the current flows through the stator coils, the coils acquire a magnetic polarity. The poles of the rotor and stator coils attract and repel depending on the polarities. The cool air comes simultaneously from opposite sides of the heat sink. For this reason the heat sink has a divider located approximately in the middle of the heat sink fins.
