摘要:
Silencing equipment provided with one or more flow channels through which cooling air flows has a flow channel forming member that forms the flow channel, and an acoustic absorbent member that is fixed to the flow channel forming member. A resonance type silencer is formed on a wall surface of the flow channel by providing a cavity for the resonance type silencer in the acoustic absorbent member and an aperture for the resonance type silencer in a portion of the flow channel forming member. The resonance type silencer sets a frequency of noise necessary to be reduced based on a peak frequency of noise generated by a fan. The silencing equipment further has a slide member which slides by a slide mechanism to adjust the area of the top of the aperture. The silencing equipment for electronic devices capable of cooling heat generating sections thereof with air has a small and simple structure and can improve a silencing effect by blowing air.

摘要:
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.
摘要:
An apparatus for cooling semiconductor devices includes a module for cooling semiconductor devices; a refrigerant cooling device for receiving via an outlet pipe the refrigerant discharged through an outlet port of the module to cool the refrigerant; a refrigerant circulation pump for receiving, via a suction pipe, the refrigerant cooled by the refrigerant cooling device and sending the refrigerant to the module via an inlet pipe; and a refrigerant-flow stabilizing mechanism for stabilizing a refrigerant circulation flow discharged from the refrigerant circulation pump to be returned to the refrigerant circulation pump via the module and the refrigerant cooling device. Since the refrigerant-flow stabilizing mechanism stabilize the refrigerant flow, the refrigerant flow can be stably circulated so that the semiconductor devices in the module are stably cooled.
