Liquid cooling system for an electronic component, comprising: - an exchanger plate having a first wall suitable to be at least partially interfaced with an electronic component to be cooled and a second wall, placed in contact with a cooling liquid, - a plurality of heat sink elements, associated with said second wall and influenced by the cooling fluid to dissipate heat, - wherein the heat sink elements are shaped according to regular patterns or strips which extend parallel to a main extension direction (X-X) and which comprise a plurality of loops, - each loop comprising a continuous curvilinear section which extends projecting from a first to a second attachment end (56,60) attached to the second wall, whereinthe continuous curvilinear section is shaped so that, a first and a second plane (P1, P2) being traced perpendicular to the second wall passing respectively through said first and second ends (56, 60), the continuous curvilinear section extends at least partially outside the space defined between said perpendicular planes (P1, P2), characterized in that a first and a second consecutive loop (48', 48") of a same regular pattern or strip are inclined in relation to the respective first perpendicular planes (P1', P1ʺ) so that the continuous curvilinear section (52ʺ) of the second loop (48") intersects the second plane (P2') of the first loop. - an exchanger plate having a first wall suitable to be at least partially interfaced with an electronic component to be cooled and a second wall, placed in contact with a cooling liquid, - a plurality of heat sink elements, associated with said second wall and influenced by the cooling fluid to dissipate heat, - wherein the heat sink elements are shaped according to regular patterns or strips which extend parallel to a main extension direction (X-X) and which comprise a plurality of loops, - each loop comprising a continuous curvilinear section which extends projecting from a first to a second attachment end (56,60) attached to the second wall, whereinthe continuous curvilinear section is shaped so that, a first and a second plane (P1, P2) being traced perpendicular to the second wall passing respectively through said first and second ends (56, 60), the continuous curvilinear section extends at least partially outside the space defined between said perpendicular planes (P1, P2), characterized in that a first and a second consecutive loop (48', 48") of a same regular pattern or strip are inclined in relation to the respective first perpendicular planes (P1', P1ʺ) so that the continuous curvilinear section (52ʺ) of the second loop (48") intersects the second plane (P2') of the first loop. whereinthe continuous curvilinear section is shaped so that, a first and a second plane (P1, P2) being traced perpendicular to the second wall passing respectively through said first and second ends (56, 60), the continuous curvilinear section extends at least partially outside the space defined between said perpendicular planes (P1, P2), characterized in that a first and a second consecutive loop (48', 48") of a same regular pattern or strip are inclined in relation to the respective first perpendicular planes (P1', P1ʺ) so that the continuous curvilinear section (52ʺ) of the second loop (48") intersects the second plane (P2') of the first loop.
