Claims10
A gas cooler for a compressor, the gas cooler comprising:
- a casing provided with a gas inlet and a gas outlet;
- a cooling unit provided inside the casing, the cooling unit being configured to divide the inside of the casing into an upstream space, above the cooling unit, to which the gas inlet opens and a downstream space, below the cooling unit, to which the gas outlet opens, the cooling unit being configured to cool gas introduced into the inside of the casing by allowing the gas to pass through the cooling unit;
- a drain recovery portion being a recess locally provided in a bottom wall defining the downstream space of the casing, the drain recovery portion being configured to accumulate drain separated from the gas by cooling the gas in the cooling unit;
- and
- a drain discharge port being an opening provided to penetrate a wall portion of the casing, the drain discharge port being configured to guide the drain accumulated in the drain recovery portion to an outside of the casing;
- wherein an upper surface of a lowermost bottom wall of the drain recovery portion inclines downward away from the gas outlet and toward the drain discharge port;
- wherein an ascending flow path extending upward from the gas outlet is formed in the casing, and
- wherein the drain recovery portion is directly below a lower end of the ascending flow path.
