ELECTRONIC UNIT Russian patent published in 2015 - IPC G12B15/00 H05K7/02 H05K7/20 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering and can be used in radio-electronic equipment blocks in which plug-in electronic modules are installed and which operate in conditions of high heat release by radio-electronic equipment components, significant mechanical loads, as well as aggressive weather conditions during field use. An electronic unit includes channels which form a coolant stream. Through said channels, which are located in the walls of the unit, the coolant stream can reach electronic modules and can also reach the inside of said modules through an opening in the housing. Other openings in the housing of the unit link said channels with the outer space. Any of the openings can be made while ensuring air-tightness.

EFFECT: providing an electronic unit with a new functional capability of cooling electronic modules by directing a coolant stream into said modules when installed in the unit, as well as improving efficiency of removing heat released by radio-electronic equipment components while saving the coolant.
