| 摘要 |
The invention relates to a device for cooling a housing of a gas turbine and/or of a combustion chamber, in particular of a gas turbine, comprising: a cooling gas supply device with a cooling gas outlet, out of which a cooling gas stream flows when the cooling gas supply device is in operation, and with a cooling gas inlet, via which the cooling gas stream flows back to the cooling gas supply device when the cooling gas supply device is in operation; and a cooling gas path which is led through the housing in the circumferential direction of the latter and which connects a first housing connection to a second housing connection. So that a circumferential temperature difference of the housing can be set independently of an average temperature of the housing, the cooling device is equipped with a switching device for reversing the flow direction.
