Abstract
A cooling system for electronic circuit components mounted on a printed circuit board, includes a cooling plate having a coolant passage, thermal contacts arranged on the cooling plate to be in resilient contact with the surfaces of the electronic components, which are cooled via the thermal contacts by liquid coolant flowing through the coolant passage. The cooling plate has one or more shortcut passages, the cross-sectional area of which is smaller than that of the coolant passage, to mutually connect predetermined portions of the coolant passage. The liquid coolant can be discharged from the cooling plate via the shortcut passage.
