Systems and methods for thermal management for telecommunications enclosures using heat pipes

摘要

Systems and methods for thermal management for telecommunications enclosures are provided. In one embodiment, a method for thermal management for modular radio frequency (RF) electronics housed within an electronics enclosure comprises: distributing heat generated from an RF electronics component installed on a first thermal region of an electronics module base plate across the first thermal region using at least one primary heat pipe that laterally traverses the first thermal region; distributing heat generated from the RF electronics component to a second thermal region using at least one secondary heat pipe not parallel with the at least one primary heat pipe; conductively transferring heat across a thermal interface between the electronics module back-plate and a backplane of an electronics enclosure that houses the electronics module, wherein the backplane comprises a plurality heat sink fins aligned with the at least one primary heat pipe and the at least one secondary heat pipe.

主权项

1. A thermal management system for electronics, the system comprising:
at least one electronics module comprising a base plate having a first thermal region and a second thermal region, wherein one or more electronic components are mounted to the first thermal region, wherein one or more primary heat pipes are embedded within the base plate and laterally positioned within the first thermal region, wherein at least one secondary heat pipe is embedded within the base plate and positioned within both the first thermal region and the second thermal region; and an electronics enclosure, housing the at least one electronics module, the electronics enclosure comprising a backplane, a top panel coupled to the backplane and a bottom panel coupled to the backplane, the backplane comprising a plurality of heat sink fins, wherein the electronics module is removably attached to the backplane of the electronics enclosure with one or more fastening systems, wherein a surface of the base plate thermally and physically interfaces with at least a planar surface of an internal surface of the backplane.
