1. A cooling system comprising:
a first cooling circuit for cooling at least one first component by means of coolant circulating in the first cooling circuit;
a second cooling circuit for cooling at least one second component by means of coolant circulating in the second cooling circuit;
a first coolant pump for circulating coolant in the first cooling circuit;
a second coolant pump for circulating coolant in the second cooling circuit; and
an expansion tank provided with an expansion chamber for accumulation of coolant, wherein the expansion chamber is connected to the second cooling circuit to allow the expansion chamber to receive coolant from the second cooling circuit; and
a first deaeration device arranged in the first cooling circuit for separation of air bubbles from the coolant circulating in the first cooling circuit, wherein the first deaeration device is located at a lower position than the expansion tank and connected to said expansion chamber via a first static line to allow air bubbles separated from the coolant in the first deaeration device to migrate upwards in the first static line towards the expansion chamber, wherein the first deaeration device comprises a deaeration chamber having:
a coolant inlet connected to a feed pipe of the first cooling circuit to allow coolant circulating in the first cooling circuit to flow from the feed pipe into the deaeration chamber via the coolant inlet a first coolant outlet connected to the first coolant pump allow coolant to flow from the deaeration chamber to the first coolant pump via the first coolant outlet, wherein the first coolant pump is arranged immediately downstream of the first coolant outlet; and
a second coolant outlet connected to said expansion chamber via the first static line wherein the second coolant outlet is located at a higher position than the first coolant outlet.
