COMBINED COOLING SYSTEM FOR ELECTRONIC UNITS Russian patent published in 2020 - IPC F26B3/12 H05K7/20 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering and can be used for efficient cooling of electronic units under different temperature conditions. Combined cooling system of electronic units comprises panel made of highly heat-conducting material, in which there are distribution channels, micro channels and channels for cooling liquid, which contain straight and bent sections. Between the straight sections of the channels, inside the panel, in the parallel plane, rods of the air cooling system are installed, having ribs on the ends extending from the panel, which is located in the cylindrical casing, which contacts the side surface with the panel and has in the end part an air fan, and the finning is made in the form of sets of alternating round and square plates with holes installed perpendicular to the rod axis. Under the panel in its central part there is coil of additional liquid cooling system with nozzles, wherein coil pipes of additional liquid cooling system in upper parts contact with panel surface, and on lower part of panel, between straight sections of coil tubing of additional liquid cooling system, ribbing is made in form of parallel to the panel of trapezoidal shaped plates with holes in the middle, and in lateral part of panel, opposite to cylindrical casing, additional fan is arranged.

EFFECT: declared combined cooling system of electronic units has a relatively simple design and enables to ensure operability of electronic units in different temperature conditions.
