Claim 10:
11. A liquid cooling system for a processing unit, the liquid cooling system comprising:
a cooling unit comprising:
an airflow unit configured to generate an airflow in a first direction along an airflow path;
a radiator unit comprising
a liquid inlet configured to receive an inflow of a cooling liquid;
a liquid outlet configured to release an outflow of the cooling liquid;
an inner liquid path configured to conduct the cooling liquid between the liquid inlet and the liquid outlet; and
an array of at least two radiator bridges, each comprising a plurality of parallel channels, the at least two radiator bridges traversing the airflow path and being spaced apart along the first direction, the at least two radiator bridges further being thermally separated from one another by gaps;

wherein a first radiator bridge of the at least two radiator bridges is configured to receive the cooling liquid from the liquid inlet to pass through its plurality of parallel channels, the first radiator bridge being the radiator bridge that is the farthest from the airflow unit;
wherein the inner liquid path is configured to conduct the cooling liquid from the liquid inlet, sequentially via the at least two radiator bridges by order of proximity to the first radiator bridge, to the liquid outlet; and
whereby the airflow generated by the airflow unit passes through the at least two radiator bridges to exchange heat between the airflow and the radiator unit;

a heat sink attached to the processing unit, the heat sink having a heat sink liquid inlet, a heat sink liquid outlet, and a heat sink liquid path configured to conduct the cooling liquid between the heat sink inlet and the heat sink outlet for heat exchange;
a cooling tube extending from the liquid outlet to the heat sink inlet;
a return tube extending from the heat sink outlet to the liquid inlet; and
a pump configured to pump the cooling liquid through the liquid cooling system to move the cooling liquid from the liquid inlet, sequentially via the at least two radiator bridges by order of proximity to the first radiator bridge, to the liquid outlet.
