LIQUID COOLER Russian patent published in 2014 - IPC H01L23/36 H01L23/42 H05K7/20 

FIELD: electricity.

SUBSTANCE: invention is related to electric engineering, in particular to cooling facilities used for power modules of electronic equipment. A plate of a heat-conductive material is used as a case of a liquid cooler, and both large sides of this plate are intended for fixation of electronic power modules or other heat-producing equipment. In one lateral edge of the plate there are drilled channels in the form of long closed holes for circulation of a cooling agent, and these holes are sealed by plugs. Channels for the cooling agent feed and discharge are made at adjacent faces by drilling of long closed holes, which cross the holes with plugs. At all faces the holes are made in the same plane. Turbulence promoters in the form of spirals made of a flat band may be installed in the channels with plugs. Ends of the turbulence promoters in the areas of holes for feed and discharge of the cooling agent may be shaped as a straight section in order to decrease hydraulic resistance in these areas.

EFFECT: improvement of fabricability and simplification of the manufacturing process, reduction of the period for maintenance and repair due to available plugs, provision of potential parallel and in-series connection of the coolers in order to regulate pressure drop and consumption of the cooling agent.
