Zusammenfassung:The invention provides a cooling device (1) for a Gas Insulated Switchgear. The cooling device (1 ) comprises a condenser (11) arranged outside the gas chamber (2), an evaporation part (13) arranged in the gas chamber, and at least one fluid conduit (12) connect the evaporator device (13) and the condenser (11); the fluid conduit (11 ) is heat conductive and is filled with low-boiling condensate (120) to transfer heat from the evaporation part (13) to the condenser (11). The evaporation part (13) and the at least one fluid conduit (12) can be integrated together, and the evaporation part (13) is the gas chamber end of the at least one fluid conduit (12). Or the condenser (11) is a separated part and it is liquid connective with al! the fluid conduits (12). The condenser (11 ) comprising a heat sink (110) which is connected with the fluid conduit (12) and is arranged outside of the gas chamber (2).
