The heat transfer performance of a gas cooler provided with a fin tube type heat exchanger is improved. This is a gas cooler 10 which is provided with a heat exchanger 6, cools a gas to be cooled, which is introduced from the outside, by performing heat exchange between the gas to be cooled and the heat exchanger 6, and discharge the cooled gas to the outside. The heat exchanger 6 includes: a plurality of heat transfer fins 8 which are placed side by side via a prescribed gap therebetween, the gas to be cooled flowing through the gap; and heat transfer tubes 7 which pierce through the plurality of heat transfer fins 8 and are provided in a plurality of rows along the direction in which the gas to be cooled flows. The outside diameter do of the heat transfer tubes 7 is 20 to 30 mm. |
