METHOD OF MANUFACTURING LIQUID COOLER Russian patent published in 2018 - IPC H01L23/36 H01L23/473 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the production of liquid coolers for devices with a high power density with a high heat release for use in electrical, radio electronic, automotive industry, in induction heating of metal. Achieved by that in the proposed method according to pre-modeled thermal conditions, on the processing center, milling of the coolant tank with coolant channels is performed. To increase the turbulence of the cooled liquid, the channel walls are made by tortuous and tapering from the base of the container to the apex, and the channels are wavy. Cooler has supply and discharge pipes with fittings for supply and removal of coolant. Thermal paste is applied along the perimeter of the sites to the places of contact of the cooler with the module. Power module is installed. Deepening along the perimeter between the module body and the cooler wall is filled with a sealant.

EFFECT: technical result is the creation of an inexpensive efficient method for manufacturing liquid coolers for cooling power modules with high technical and operational characteristics.
