Systems and methods for heat extraction in a power supply

摘要

Power supply and heat sink modules are suitable for use in sealed outdoor enclosures. Circuit elements in the power supply modules are connected to multiple heat sinks. The heat sinks are combined in heat sink modules. The heat sink modules provide high thermal conductivity while avoiding electromagnetic interference.
