Abstract

There is disclosed a liquid-cooled electronic device. Semiconductor devices are mounted on a substrate of a semiconductor module immersed in a cooling liquid. A wire-like member is provided in the vicinity of a cooling medium ejection port of each cooling medium supply member which cools a respective one of the semiconductor devices by a jet of the cooling liquid. With this arrangement, the flow of the cooling liquid downstream of the wire-like member is disturbed to promote the boiling over the entire surface of the semiconductor device, and when the semiconductor device is to be cooled, a transient temperature rise is reduced at the time of starting the energization of the semiconductor device, thereby stabilizing the temperature of the semiconductor device.
