Abstract
A liquid cooling system for cooling an electrical component, the liquid cooling system including a cooling circuit having at least one supply branch for supplying liquid coolant to an electrical component; and a de-aeration line to provide a connection between a high point and a junction point of the cooling circuit to bypass a part of the cooling circuit; wherein the pressure of the liquid coolant is lower in the junction point than in the high point during circulation of the liquid coolant in the liquid cooling system.

A liquid cooling system for cooling at least one electrical component, the liquid cooling system comprising:
- a cooling circuit having an inlet flow line, a return flow line, and at least one supply branch for supplying liquid coolant to an electrical component;
- and
- at least one de-aeration line to provide a connection between a high point and a junction point of the cooling circuit to bypass a part of the cooling circuit;
- wherein the high point constitutes a geodetically or locally highest point of the at least one supply branch;
- wherein the junction point is provided on the return flow line downstream of the at least one supply branch;
- wherein the pressure of the liquid coolant is lower in the junction point than in the high point during circulation of the liquid coolant in the liquid cooling system.
A method of operating a liquid cooling system for cooling at least one electrical component, the method comprising the steps of:
- circulating liquid coolant in a cooling circuit having an inlet flow line, a return flow line, and at least one supply branch for supplying liquid coolant to an electrical component;
- and
- connecting at least one high point and a junction point of the cooling circuit to bypass a part of the cooling circuit;
- wherein the high point constitutes a geodetically or locally highest point of the at least one supply branch;
- wherein the junction point is provided on the return flow line downstream of the at least one supply branch;
- wherein the pressure of the liquid coolant is lower in the junction point than in the high point.
