HEAT DISSIPATER, HEAT DISSIPATION METHOD FOR COMMUNICATION DEVICE, AND COMMUNICATION DEVICE

摘要

Embodiments of the present invention disclose a heat dissipation device, including: a closed shell and a temperature control device. The temperature control device includes: a cold storage medium module, a first group of thermosiphons, and a second group thermosiphons; wherein the cold storage medium module is disposed at the outside of the closed shell, the first group thermosiphons are provided with a first group of evaporation ends and a first group of condensation ends, and the second group of thermosiphons are provided with a second group of evaporation ends and a second group of condensation ends; the first group of evaporation ends are disposed at the inside of the closed shell, and the first group of condensation ends are disposed in the cold storage medium module; the second group of evaporation ends are disposed in the cold storage medium module, and the second group of condensation ends are disposed in environmental air; the first group of condensation ends are disposed above the first group of evaporation ends in the direction of gravity, and the second group of condensation ends are disposed above the second group of evaporation ends in the direction of gravity. Embodiments of the present invention also disclose a communication device and a heat dissipation method for a communication device. The above technical solutions save electric energy and improve the effects of energy saving and emission reduction of the system.
