Heat dissipation apparatus and outdoor communication device

Abstract

A heat dissipation apparatus comprises: one or more thermosiphon heat exchange units, one or more first partitions, and a frame having at least two lattices; wherein, each of the one or more thermosiphon heat exchange units is embedded in one lattice of the at least two lattices; each lattice of the at least two lattices having no thermosiphon heat exchange unit embedded is disposed with the first partition to partition the lattice into an upper portion and a lower portion, where the first partition is detachable. The outdoor communication device comprises the heat dissipation apparatus and one or more service board. Through a modular design, the number of the embedded thermosiphon heat exchange units can be increased or decreased at any time depending on heat dissipation performance that is required.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of International Application No. PCT / CN2011 / 074103, filed on May 16, 2011, which is hereby incorporated by reference in its entirety.TECHNICAL FIELD[0002]The present application relates to heat exchange techniques, and more specifically, to a heat dissipation apparatus and an outdoor communication device.DESCRIPTION OF THE RELATED ART[0003]In communication networks, there are a large number of outdoor communication devices arranged in open fields, for example, large power cabinets of communication base stations. Because these outdoor communication devices produce heat in their operation, and they can only operate appropriately in a certain range of temperatures, heat dissipation apparatus must be disposed for these outdoor communication devices.[0004]FIG. 1 is a schematic structure diagram of a heat dissipation apparatus in the prior art. As shown in FIG. 1, the heat dissipation apparatus comprises: an i...

Benefits of technology

[0013]From the above technical solution, it can be seen that, in embodiments, through modular design, the frame of a heat dissipation apparatus may have a plurality of lattices in each of which a thermosiphon heat exchange unit can be embedded, the number of the embedded thermosiphon heat exchange units can be increased or decreased at any time depending on heat dissipation performance that is required, the synchronized update of the heat dis

Problems solved by technology

Because these outdoor communication devices produce heat in their operation, and they can only operate appropriately in a certain range of temperatures, heat dissipation apparatus must be disposed for these outdoor communication devices.

After update, there may be a change in the working power of an outdoor communication device, as a result, a heat dissipation apparatus provided in the original construction of a communication network may be no longer suitable for the updated outdoor communication device.

Presently, in the design of a heat dissipation apparatus, if the probability of sequential updates of an outdoor communication device is considered, the heat dissipation apparatus has to be designed according to the working power when a maximum number of servi
