HEAT EXCHANGER, HEAT DISSIPATION METHOD OF SAME AND COMMUNICATION APPARATUS

摘要

Provided are a heat exchanger (100), a heat dissipation method of same and a communication apparatus, wherein the heat exchanger (100) includes a first air passage (20) and a second air passage (40). The first air passage (20) and the second air passage (40) are separated from each other. The first air passage (20) is provided with a first fan unit (22) and a first group of heat dissipation tubules (24). The second air passage (40) is provided with a second fan unit (42) and a second group of heat dissipation tubules (44). The upper ends (247) of the first group of heat dissipation tubules (24) along the gravity direction are communicated via a steam manifold (80) with the upper ends (447) of the second group of heat dissipation tubules (44) along the gravity direction. The lower ends (249) of the first group of heat dissipation tubules (24) along the gravity direction are communicated via a liquid manifold (60) with the lower ends (449) of the second group of heat dissipation tubules (44) along the gravity direction. A closed pipeline, which is filled with vaporized liquid when heated, is formed by the first group of dissipation tubules (24), the steam manifold (80), the second group of dissipation tubules (44) and the liquid manifold (60). Heat dissipation fins (2411) are set among the first group of dissipation tubules (24) and the second group of dissipation tubules (44).
