Power amplifier system waterproof construction

The utility model provides a power amplifier system waterproof construction, power amplifier system waterproof construction includes system's main circuit cavity and locates the outer power module of system's main circuit cavity, if the main circuit module of responsibility interconnected system in system's main circuit cavity, the surface of system's main circuit cavity has been laid heat sinkly, a plurality of system owner circuit module are through running through system's main circuit cavity reaches the aluminium threading of heat sink setting pipe with power module carries out electric connection, just the both ends of aluminium threading pipe are encircled respectively and are equipped with a waterproof gasket. The utility model provides a power amplifier system waterproof construction, not only waterproof performance is good for it, and the owner circuit module of its system is difficult for receiving the electromagnetism to interfere moreover.
