Abstract

The invention discloses a power amplifier module carrying device in a satellite communication system, comprising a shell and a heat radiating plate. A work room is arranged above the heat radiating plate, and a heat radiating room is arranged below the heat radiating plate. Baffles are arranged inside the work room, the baffles contact a GaN power amplifier module. An air inlet pipe and a heat radiating fan are arranged above the GaN power amplifier module. The baffles penetrate through the heat radiating plate to the bottom of the heat radiating room. An overflow plate is arranged on each baffle. The heat radiating room is provided with a spray plate inside, and sprinkler heads are arranged on the spray plate. The water pipes inside the sprinkler heads are connected with a main water pipe arranged inside the spray plate. The main water pipe penetrates through the side of the heat radiating room and is connected with a water inlet pipe. The water inlet pipe is connected with a micro water pump. The micro water pump is connected with a cooler through a water pipe. A water outlet pipe is arranged below the water inlet pipe, and the water outlet pipe is communicated with the heat radiating room and the cooler. The temperature of a GaN power amplifier module in a solid-state power amplifier is efficiently reduced by a main water cooling system and an auxiliary air cooling system, so the work efficiency of the GaN power amplifier module is improved, and the room for improvement of the solid-state power amplifier is improved.
