An ultra-low liquor ratio fabric dyeing machine includes an assisting heat exchanger and a direct temperature rise/lowering device. The assisting heat exchanger or multiple ones of the assisting heat exchanger are additionally included in the dyeing machine. The assisting heat exchanger includes an external pipe that is mounted to a pump pipe of a pump at an inlet port, an outlet port, or both inlet and outlet ports thereof and is mounted with inlet and outlet openings for steam and cooling water in order to serve as an external casing that houses the pump pipe, while the pump pipe serves as a heat exchange pipe of the heat exchanger. The direct temperature rise/lowering device is mounted to a dyeing bath of the dyeing machine to directly introduce steam or cold water therein for quickly increasing or decreasing the temperature of the dyeing bath.
