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.
