COOLER OF RADIO ELECTRONIC EQUIPMENT Russian patent published in 2008 - IPC H05K7/20 

FIELD: physics.

SUBSTANCE: invention is related to radio electronic equipment, in particular to cooling radio electronic equipment and may be used for cooling elements of radio electronic equipment operating under cyclical thermal influences. Technical result is achieved by intensifiying of cooling and hardening processes of melted fillers during interruption of radio element operation by means of application of thermal electric battery. Cooler of radio electronic equipment consists of thin-walled metal reservoir divided, by metal partitions installed parallel to plane of cooled radio elements location, into isolated sections filled with melted fillers with different melting temperatures that increase in direction to plane of cooled radio elements installation. Top section (having the largest area), whereon cooled radio element is installed, has, as a filler, substance with the lowest melting temperature, and every subsequent section is smaller than the previous one in area, and is filled with melted filler with melting temperature higher than that of the previous one. Thermal electric modules are adjacent as soldered joints to bottom surfaces of sections in part that protrudes above the following sections. Second soldered joints of thermoelectric module are installed on heat-absorbing soldered joint of the bottom basic cascade of thermoelectric battery, which is also thermally contacted with central area of metal reservoir surface opposite to installation of cooled radio elements. To heat-release soldered joint of basic thermoelectric battery radiator is connected. Thermoelectric battery is supplied by source of electric energy.

EFFECT: ruling out limitations for duration of pause in radio element operation.
