ELECTRONIC UNITS COOLING SYSTEM Russian patent published in 2019 - IPC H05K7/20 

FIELD: cooling.

SUBSTANCE: invention relates to cooling systems of electronic units of various equipment, including radioelectronic systems operating at different temperature modes. Technical result is achieved by the fact that the system for cooling electronic units comprises a panel of highly heat-conducting material, in which there are distribution channels, micro channels, cavities and channels for cooling liquid, comprising straight and curved sections, channel inlet and outlet have unions, channels contain elements creating turbulence; to the side part of the panel a casing with an air fan is connected, consisting of two hollow cylinders connected by a conical transition, wherein the panel is attached to the side cylindrical surface of the larger hollow cylinder, air fan is installed in conical transition, in addition, between straight sections of channels for cooling liquid, inside panel hollow rods of air cooling system are installed, which enter by ends with finning in casing, wherein in the larger hollow cylinder area on the ends extending from the panel the finning is made in the form of a set of coaxially located rings, the external one of which is connected to the end of the hollow rod, and the inner rings are fixed to the external one by means of radial spokes, finning of rods located in the zone of smaller hollow cylinder is semi-circular plates attached at right angle, between straight sections of channels not occupied by hollow rods of cooling system there are cavities communicating with environment through holes arranged in staggered order, and with inner volume of casing in zone of smaller hollow cylinder through micro channels having ejectors at end.

EFFECT: improving cooling efficiency with simplification of system design.
