COMBINED SUBSTRATE WITH LIQUID COOLING AND MANUFACTURING METHOD OF COMBINED SUBSTRATE WITH LIQUID COOLING Russian patent published in 2015 - IPC G12B15/02 G12B15/06 H05K7/20 H01L23/34 

FIELD: metallurgy.

SUBSTANCE: invention relates to a metal-ceramic fixed substrate, and namely to a combined substrate with liquid cooling, and to its manufacturing method. Combined substrate 1 with liquid cooling, in which metal mounting plate 15 made from aluminium or an aluminium alloy, is connected to one surface of ceramic substrate 10, one surface of plate-like metal base plate 20 made from aluminium or an aluminium alloy is connected to other surface of ceramic substrate 10, and radiator 30 of a liquid cooling type, which consists of extrusion material, is connected to other surface of metal base plate 20, in which the ratio of thickness t1 of metal mounting plate 15 to thickness t2 of metal base plate 20 meets t2/t1≥2, where thickness t1 of metal mounting plate 15 is 0.4 to 3 mm, and thickness t2 of metal base plate 20 is 0.8 to 6 mm.

EFFECT: reduction of costs for materials and production, reduction of bending (deformation of shape), and improving strength and heat-radiating productivity.
