  • HEAT EXCHANGER, HEAT DISSIPATION METHOD OF THE SAME AND COMMUNICATION APPARATUS
    Publication number: 20120147562
    Abstract: A heat exchanger, a heat dissipation method and a communication apparatus are provided. The heat exchanger includes a first and a second air passage separated from each other. The first air passage has a first fan unit and a first group of heat dissipation tubules. The second air passage has a second fan unit and a second group of heat dissipation tubules. The upper ends of the first and second group of heat dissipation tubules are communicated with each other via a steam manifold. The lower ends of the first and second group of heat dissipation tubules are communicated with each other via a liquid manifold. A closed pipeline filled with liquid vaporized when heated, is formed by the first and second group of dissipation tubules, the steam manifold and the liquid manifold. Heat dissipation fins are set among the first and second group of dissipation tubules.
