Water-cooled power combiner for high-power solid-state amplifiers
ActiveCN106952881BRealize the idea of water coolingImprove cooling efficiencySemiconductor/solid-state device detailsSolid-state devicesElectrical conductorPower combiner
The invention discloses a water-cooled power combiner for a high-power solid state power amplifier. The water-cooled power combiner for a high-power solid state power amplifier comprises an inner conductor, a central conductor, a connecting conductor, a first outer conductor, a second outer conductor, a third outer conductor and an input port; the central conductor is arranged at one end of the inner conductor; the first outer conductor, the second outer conductor and the third outer conductor are arranged outside the inner conductor and the central conductor; and a first water channel and a second water channel are respectively arranged at the position near the central conductor inside the third outer conductor and the second outer conductor. According to the invention, the inner and outer double-layer structure is adopted by the water-cooled power combiner provided by the invention, and the water-cooling channel is arranged in the outer structure, therefore, the water-cooling heat dissipation of the multi-channel power combiner is realized, and the idea of water-cooling for the power combiner is realized. The water-cooled power combiner has the advantages of high heat dissipation efficiency, small space occupation, omitting external heat dissipation mechanism, convenient for maintenance and service, and can realize the circulating cooling of the power amplifier plug-in unit.
