Claim 0:
1. A liquid cooling module comprising:
a main body comprising:
a cooling core comprising a microfluidic structure configured to carry a cooling liquid; and
a plurality of slots;

a sealing pad configured to transmit heat from an electronic device to the cooling core; and
a plurality of fins extending from the main body, each of the plurality of fins comprising an internal circulating liquid duct such that the liquid cooling module comprises a plurality of internal circulating liquid ducts in fluidic communication with the microfluidic structure;
wherein a first fin of the plurality of fins comprises a first internal circulating liquid duct comprising:
a first portion connected to a first slot of the plurality of slots and configured to lead the cooling liquid away from the cooling core;
a second portion connected to a second slot of the plurality of slots and configured to lead the cooling liquid towards the cooling core; and
an intervening portion connecting the first portion and the second portion of the first fin;

wherein a second fin of the plurality of fins includes a second internal circulating liquid duct configured to receive the cooling liquid from the first internal circulating liquid duct via the second slot of the plurality of slots, the second internal circulating liquid duct comprising:
a first portion connected to the second slot of the plurality of slots and configured to lead the cooling liquid away from the cooling core;
a second portion connected to a third slot of the plurality of slots and configured to lead the cooling liquid towards the cooling core; and
an intervening portion connecting the first portion and the second portion of the second fin;

wherein the first internal circulating liquid duct is configured so that the flow of the cooling liquid along the first internal circulating liquid duct is in a first rotation direction; and
wherein the second internal circulating liquid duct is configured so that the flow of the cooling liquid along the second internal circulating liquid duct is in a second rotation direction opposite the first rotation direction.
