Abstract

A passive two-phase cooling circuit includes a vaporizer and a condenser for a coolant conducted in the cooling circuit. A vaporizer supply line and a vaporizer discharge line are connected to the vaporizer, and a condenser supply line and a condenser discharge line are connected to the condenser. The cooling circuit has a simple and cost-effective structure which reduces or even completely prevents pressure shocks during operation by connecting the vaporizer supply line, the vaporizer discharge line, the condenser supply line and the condenser discharge line to a common damping container. A liquid column forms in the condenser discharge line during the operation of the cooling circuit and the column assumes the function of a liquid-tight seal and of a fluid-dynamic vibration damper.
