Embodiment Construction

[0023] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0024] The working principle of the multi-pipe fixed-point "jet flow" air-cooled heat dissipation device of the large-scale active phased array radar TR component is: a large amount of air generated by a single fan is transported to the antenna through multiple pipes in the equal pressure cabin, and the jet holes on the pipes are used to The generated jet blows to the surface of the columnar cooling teeth at the concentrated heat source on the TR component, using the jet cooling to efficiently reduce the local thermal gradient and provide higher heat dissipation performance than ordinary air-cooled heat dissipation. The hot air generated by the jet passes through the air outlet, Blow out the antenna.

[0025] The multi-tube fixed-point "jet flow" air-cooled heat dissipation device is mainly composed of fans, equal pressure cabins, ventilation ducts and columnar c...

Abstract

The invention relates to a multitube fixed-point jet air cooling radiator of a TR assembly of radar. A large amount of air generated by a single draught fan is conveyed to an antenna in a constant-pressure cabin through a plurality of pipelines, jet flow generated by jet flow holes in the pipelines is blown to a columnar cooling tooth surface on a concentrated heat source on the TR assembly, the local heat gradient is efficiently reduced through jet flow cooling, cooling efficiency higher than common air cooling heat radiation is provided, and hot air generated by the jet flow is blown out of the antenna through an air outlet channel.

Description

technical field [0001] The invention relates to the technical fields of machinery and radar, in particular to a large-scale active phased array radar antenna air-cooled and heat-dissipating heat dissipation device, which can be applied to the field of military and civilian products that require high heat dissipation of dispersed high-heat-flux electronic equipment. Background technique [0002] An important direction of radar development today is to increase the radar range, improve radar measurement accuracy, and effectively combat various clutter and low-observable targets. Regardless of the frequency band and purpose of the active phased array radar, there are as few as hundreds or as many as thousands of T / R components. TR components are the core equipment of active phased array radar, and temperature has a great influence on the performance of TR components. All TR components are required to be in the same temperature range during operation, and the temperature differen...
