Abstract

The invention discloses a heat dissipation assembly of phased-array antenna and a heat dissipation device, and the heat dissipation assembly comprises a rectangular T / R assembly, the surface of one side of the T / R assembly is symmetrically provided with two groups of heat dissipation fins with the same structure, and a fixed region is arranged between the two groups of heat dissipation fins; the heat dissipation fins comprise a plurality of first heat dissipation fins which are arranged in parallel; a rectangular wave control module is fixed in the fixed region, a plurality of second heat dissipation fins are arranged on the surface of one side of the wave control module in parallel, and the second heat dissipation fins are perpendicular to the wave control module; according to the heat dissipation assembly provided by the invention, the inclined heat dissipation fins are arranged on the surfaces of one sides of the T / R assembly and the wave control module, and the T / R assembly and the wave control module are arranged in a T shape, so that the heat dissipation efficiency of the single-point heat production module can be improved, the temperature rise superimposed effect can be weakened, the heat dissipation channel can be optimized, and natural air cooling heat dissipation of the phased-array antenna can be realized.

Description

technical field [0001] The invention relates to the field of phased array antennas, in particular to a heat dissipation component and a heat dissipation device of a phased array antenna. Background technique [0002] The phased array antenna is one of the most important components in the radar, and it is also the component that generates the most heat in the radar. As the main active components of the phased array antenna, the T / R component, the secondary power supply and the wave control module are the heat generating components and also the key parts that affect the performance of the phased array antenna. In order to ensure reliable operation, corresponding heat dissipation measures must be taken to ensure that the T / R components, secondary power supply and wave control module work within a suitable temperature range. [0003] Conventional heat dissipation methods for phased array antennas include natural air cooling, forced air cooling, and liquid cooling. With the rapi...
