The invention discloses a high-speed maglev train eddy current braking heat exchange system in a vacuum pipeline. The high-speed maglev train eddy current braking heat exchange system comprises a train heat exchange system; the train heat exchange system comprises a brake cooling pipeline which passes through the eddy current brake system and is provided with a heater and a first pump; a liquid outlet of the liquid storage device is communicated with a liquid inlet of the brake cooling pipeline; a liquid inlet of the proportional three-way valve is communicated with a liquid outlet of a brake cooling pipeline, and liquid outlets of the proportional three-way valve are respectively arranged on a first branch and a second branch which are communicated with the liquid storage device; a heat storage material is arranged in the heat accumulator; and the heat accumulator and the second branch are communicated with a cold charging circulating pipeline of a station cold charging system arranged on the station. Compared with the prior art, the system has the beneficial effects that in the running process of the train, heat in the eddy current braking system is temporarily stored in the heat accumulator, and when the train stops, cold charging and heat exchange are conducted on the heat accumulator through the station cold charging system, so that the problem that a braking device of the train is difficult to dissipate heat in the vacuum environment is solved.
