DEVICE FOR COOLING ELECTRONIC PRODUCTS Russian patent published in 2018 - IPC H05K7/20 

FIELD: electrical engineering.

SUBSTANCE: invention is related to electronic engineering. It is achieved by the fact that the device for cooling electronic products comprises a sealed reservoir filled with a cooling liquid, with a cover, inlet and outlet nozzles communicating by means of a pipeline with a pump and an external heat exchanger. Device is provided with a first partition installed in the lower part of the reservoir and extending parallel to its entire bottom to form a first chamber. Second and third partitions are installed on the first partition near the side walls of the reservoir and parallel to them and form the second and third chambers. Fourth partition is installed on the first partition near one of the end walls of the reservoir and parallel to it to form a fourth chamber. Fifth chamber is designed for installation of cooled electronic products. First partition has inlet openings of different diameters, so that when installing electronic products on it, the centers of orthogonal projections of the most heated electronic components on its surface coincide with the centers of these openings, and the diameter of each inlet opening is proportional to the heat release power of that electronic component, on the orthogonal projection of which this opening is located. According to another embodiment of the invention, an end of the bent pipe is passed into each inlet opening, with inlet openings of different diameters in the upper part of the bent pipe. First partition can be made in the form of separate modules with openings. In the case where electronic products are not installed over the entire volume of the fifth chamber of the reservoir, openings are not made in the empty modules.

EFFECT: increased and equated rate of selection of heated cooling liquid from each electronic product characterized by varying degrees of heating, providing simultaneous supply of different volumes of cooling liquid, proportional to their heat output, to them.
