Abstract

The invention relates to a cooling structure (1) for a cylinder head (2) of an internal combustion engine with at least two exhaust valves (3, 4) and at least one intake valve (5, 6) per cylinder, wherein at least one exhaust valve bridge (8) is located between two adjacent exhaust valves (3, 4) and at least two intake-exhaust valve bridges (10, 11) are located each between an exhaust valve (3, 4) and an adjacent intake valve (5, 6), the cooling structure (1) comprising a lower first cooling jacket (12) adjacent to a fire deck (13) and an upper second cooling jacket (14) adjacent to an intermediate deck (15), the first and second cooling jackets (12, 14) being flow connected by at least one transfer opening (27, 31) of the intermediate deck (15), the first cooling jacket (3) including at least one centre cooling chamber (17) and an outer cooling chamber arrangement with at least one first outer cooling chamber (16), the outer cooling chamber (16) and the centre cooling chamber (17) being flow connected by at least one exhaust side first radial passage (19) extending in a region of the exhaust valve bridge (8) and by at least one second radial passage (20, 21), wherein the first radial passage (19) and the second radial passage (20, 21) are streamed hydraulically in parallel. The outer cooling chamber arrangement of the first cooling jacket (3) comprises at least one first outer cooling chamber (16) and at least one second outer cooling chamber (29) which is separated from the first outer cooling chamber (16) by at least one flow restricting passage, wherein the second outer cooling chamber (29) is flow connected with the centre cooling chamber (17) by at least one intake radial passage (24, 25, 26) extending in a region of an intake valve bridge (9) and/or in a region of the intake-exhaust valve bridge (10, 11).
