Abstract
An electronic device cooler for cooling an exothermic member arranged in a case, comprises: an air compressor for adiabatically compressing the air in the case; a heat pipe for discharging the heat of the air, which is compressed to have an elevated temperature by the air compressor, to the outside of the case; and an expansion turbine for adiabatically expanding the pressurized air, which is derived of its heat by the heat pipe, to cool it.
Claims8
An electronic device cooler for cooling a plurality of exothermic members, as arranged in a case, with an air flow established by a cooling fan, comprising:
- a heat pipe having portions partially and in series connected to said plurality of exothermic members in a heat transferable manner;
- a radiation unit, to which another portion of said heat pipe is connected in a heat transferable manner and configured to be cooled by said air flow;
- and
- an electromagnetic shield plate, to which said plurality of exothermic members are attached in a heat transferable manner and along which said heat pipe is arranged.
