Abstract

An aspect of the present invention relates to an apparatus (1) for liquid cooling at least one integrated circuit (IC1, IC2, IC3), comprising: at least one heat-conducting plate (10) configured to be in thermal contact with the at least one integrated circuit (IC1, IC2, IC3); a casing (20) to which the at least one heat-conducting plate (10) is attached, the casing (20) comprising: an inlet section (30) comprising an inlet (31) for receiving a cooling liquid (CL); a manifold section (40) that is tapered and configured to control a flow (F) of the cooling liquid (CL) from the inlet section (30) into the manifold section (40) and change a flow direction of the cooling liquid (CL) from a first direction (D1) from the inlet section (30) into the manifold section (40) to a second direction (D2) transverse to the first direction (D1), the first direction (D1) and the second direction (D2) being parallel to a principal plane (11) of the at least one heat-conducting plate (10); a flow input control section (50) comprising a plurality of solid flow input control segments (51) that form flow input passages (52) between them and are configured to control the flow (F) of the cooling liquid (CL) in the second direction (D2) from the manifold section (40) into a cooling section (60) of the casing (20); the cooling section (60) comprising a plurality of heat sink elements (61, 64) at least a part of which is in thermal contact with the at least one heat-conducting plate (10) and that are configured to transfer heat from the at least one heat-conducting plate (10) to the cooling liquid (CL) flowing from the flow input control section (50) through the cooling section (60); and an outlet section (70) comprising an outlet (71) for outputting the cooling liquid (CL) from the cooling section (60). Another aspect relates to a vehicle (1000) comprising such an apparatus (1).
