FIELD: electricity.
SUBSTANCE: electronic unit is formed by no less than two interconnected electronic modules with thermal radio elements being installed on heat removing layer of printed circuit. Non-thermal radio elements are available on the other side of printed circuit. Besides the ends of heat removing layer in printed circuit are projected from the circuit and form pipe shape. Metal housing is formed with heat removing layers of printed circuits in electronic modules. The pipe made up from heat removing layers is in rectangular form. The housing walls are provided with cooling ribs and there is a heat insulating layer between printed circuit and its heat removing layer. The heat removing layers of printed circuits may have multiple layer conductive coating.
EFFECT: effective heat removal and shielding from electromagnetic fields.
