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.

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.

AI Technical Summary

Benefits of technology

[0006]A heat dissipation apparatus is provided in one embodiment for addressing defects in the prior art and lowering manufacturing cost.

[0007]An outdoor communication device is provided in one embodiment for addressing defects in the prior art and lowering manufacturing cost.

[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 dissipation apparatus with the device where the heat dissipation apparatus is disposed can be implemented, a waste in cost caused when the heat dissipation apparatus is designed according to its maximum required heat dissipation performance can be avoided, and manufacturing cost can be saved. Furthermore, the heat dissipation apparatus is plug-and-play, which may facilitate mount and maintenance, and the update requirement of devices can be met.

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 service boards are provided for the outdoor communication device, thereby, manufacturing cost may increase, and there may be a waste in cost if the outdoor communication device is not provided with a maximum number of service boards.

However, if a heat dissipation apparatus is provided only according to the working power of an outdoor communication device specified in the original communication network construction, if a update is needed for the outdoor communication device later, the outdoor communication device must be replaced as a whole, leading to a larger waste in cost.

In summary, the existing heat dissipation apparatus can not be updated synchronization with outdoor communication devices, leading to waste in production cost of outdoor communication devices.
