In the inverter, an electronic device is disposed inside a first enclosure; a heat radiator and a cooling fan are disposed inside a second enclosure; a magnetic element is disposed outside the first enclosure and the second enclosure. In this way, the cooling effect on the electronic device inside the first enclosure and the heat radiator inside the second enclosure are increased as they may be less affected by the heat generated by the magnetic element. It is also beneficial to heat dissipation of the magnetic element. The cooling fan blows the heat radiator for heat dissipation; the magnetic element does not block the relatively cold air flowing through the heat radiator. Therefore, a less obstructed air duct is formed, and the dissipation effect is improved.

  • Patent number: 9063305
    Abstract: A heat dissipation solution is provided that is suitable for use in, but not limited to use in, CXP modules. The heat dissipation solution allows the performance of a CXP module to be significantly improved without having to increase the size of the heat dissipation device that is currently used with known CXP modules. The heat dissipation solution thermally decouples the heat dissipation path associated with the laser diodes from the heat dissipation path associated with other heat-generating components of the module, such as the laser diode driver IC and the receiver IC. Decoupling these heat dissipation paths allows the temperature of the laser diodes to be kept cooler as they are operated at higher speeds while allowing the temperatures of the other components to run hotter, if desired or necessary.
