Abstract
The invention is a cooling apparatus for electronically steered phased array antennas in radar systems. The apparatus includes a rigid tube, used in multiplicity with a series of identical apparatus, located adjacent to the transmitter/receiver modules in the antenna and having a plurality of longitudinal slots. Flexible hoses are inserted into the tubes so that when a liquid coolant is introduced under pressure into the hoses, the fluid pressure will be sufficient to cause expansion of the flexible hose material enough so the material expands outward through the slots in the tubes and becomes flush against the side of the transmitter/receiver modules, thereby maximizing heat transfer between the modules and the liquid coolant.
