A cooling system of the present disclosure includes: a coolant tank storing a coolant removing heat from a heating element in a closed space as an inner space; a plurality of heat pipes that are arranged to extend from the coolant tank toward the outside of the coolant tank and respectively having passages allowing the coolant as a working fluid to be movable therethrough; and a blower fan blowing air to the plurality of heat pipes from the outside of the coolant tank in a direction in which the heat pipes are arranged, wherein a cross-sectional shape orthogonal to the extension direction of each heat pipe is a flat plate shape having a leading edge on an upstream side of a blowing direction of the blower fan and a trailing edge on a downstream side thereof with the blowing direction as a longitudinal direction.

In a communicating structure between combustors that generates combustion gas inside pipe pieces and a turbine portion that generates a rotational driving force by making the combustion gas sequentially pass through a turbine stage formed of turbine stator vanes and turbine rotor blades, at least some of the first-stage turbine stator vanes closest to the combustor among the turbine stator vanes are disposed downstream of sidewalls of one pipe piece and another pipe piece that are adjacent to each other, and the distance from leading edges of the first-stage turbine stator vanes disposed downstream of the sidewalls of the pipe pieces to end portions of the sidewalls closer to the turbine portion is equal to or less than a spacing between an internal surface of the sidewall of the one pipe piece and an internal surface of the sidewall of the other pipe piece.
