This invention provides a multi-channel audio and video synchronous network transmitter, including a housing with a top cover. Symmetrical through-slots are formed on both sides of the housing. A cooling fan is mounted on the lower surface of the top cover. A heat dissipation assembly is provided on the housing. The heat dissipation assembly includes a support mesh, a guide sleeve, a magnetic ring, a mounting cover, an external filter plate, a spring, a fixing seat, and a guide rod. The guide sleeve is fixedly connected to the outer wall of the housing and corresponds to the position of the through-slots. With the help of the cooling fan, external air enters the housing through the through-slots on both sides and is then exhausted from the top, thus achieving heat dissipation. During this process, the air entering the housing is filtered by a filter element to ensure clean air and prevent dust and impurities from adhering to the circuit board.
