摘要:
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.

The present invention is directed to an iron, aluminum, chromium, carbon alloy and a method of producing the same, wherein the alloy has good room temperature ductility, excellent high temperature oxidation resistance and ductility. The alloy includes about 10 to 70 at. % iron, about 10 to 45 at. % aluminum, about 1 to 70 at. % chromium and about 0.9 to 15 at. % carbon. The invention is also directed to a material comprising a body-centered-cubic solid solution of this alloy, and a method for strengthening this material by the precipitation of body-centered-cubic particles within the solid solution, wherein the particles have substantially the same lattice parameters as the underlying solid solution. The ease of processing and excellent mechanical properties exhibited by the alloy, especially at high temperatures, allows it to be used in high temperature structural applications, such as a turbocharger component.
