RADIO ELECTRONIC UNIT Russian patent published in 2018 - IPC H05K7/20 

FIELD: radio equipment; electronics.

SUBSTANCE: invention relates to the structures of on-board and ground-based radio-electronic apparatus and equipment. Result is achieved by the fact that in the radio-electronic unit containing a base, a set of printed circuit boards that are connected in parallel to each other into the package, in which each printed circuit board is mounted in a frame of heat and electrically conductive material, mounted with their ends on the base, a heat-conducting gasket is provided between the base and the frames in the form of a minimum of two outer layers of foil, between which there is a layer of heat-conducting paste or only in the form of a heat-conducting paste, the radio-electronic unit being installed on the heat-removing surface through the heat-conducting paste. At the same time, the frames interact with each other by means of grooves and protrusions that are formed along the perimeter of the end face of each frame and form a labyrinth connection when they are joined. Moreover, the side frames are provided with covers which, with the outer surfaces of the frame of the unit, have a current-conductive coating and are joined by straps by means of a threaded connection, and one of the frames is connected to the base of the unit by means of an electrically conductive bridge.

EFFECT: increase in the efficiency of the electronic unit by ensuring reliability through the improvement in heat transfer and removal of electrostatic charge.
