RADIATOR DESIGN AS PART OF BEAMFORMER RACK

Abstract

The design-engineering techniques to improve hydraulic and, accordingly, thermal characteristics of the liquid cooling radiator of the communications-electronics equipment (CEE) beamformer rack are presented. The liquid cooling method of CEE permitting to remove heat flows from small areas is considered. CAD-CAE simulation of the cooling fluid in the channel is performed, and its hydrodynamic characteristics at the preset parameters of the coolant and the environment are studied. The following tasks are solved: a beamformer rack solid model involving non-type designs is built, the mathematical simulation of the hydrodynamic processes is done, the technique of increasing the flow turbulence is developed, the numerical analysis of the proposed design is presented, the results of the theoretical research and the experiment are compared. The suggested design is producible, particularly the product assembly is not difficult and permits the use of automation devices, such as power tools.
