PASSIVE COOLING SYSTEM OF RADIO ELEMENTS OF ELECTRONIC UNITS Russian patent published in 2016 - IPC G06F1/20 H05K7/20 

FIELD: radio engineering.

SUBSTANCE: passive cooling system of radio elements of electronic units relates to radio electronics, in particular, to devices scattering heat from loaded sources of heating electronic units and microwave modules used in field conditions, located on rotating areas of a structure and subjected to various climatic effects. Said technical result is achieved due to that, that in the known device containing fuel radio elements, surfaces of which through heat interfaces are connected to evaporation zones of heat pipes, from which heat energy is transferred to the condensation zone, a direct contact is provided of the (radioelement) heating source with the heat pipes, which are brought outside the housing of the electronic unit and brazed with the radiator plates rigidly interconnected with limiters, herewith the cooling system has the minimum number of assemblies mechanical connections and operates in any vector position.

EFFECT: technical result of the declared invention is higher reliability of structure of the cooling system capable of stable operation in autonomous mode, in any vector direction, longer service life of electronic units, ensuring stability of heat removal and maintaining their temperature within the required range at simultaneous reduction of weight and dimensions due to reduction of coupling mechanical connections.
