The invention relates to the technical field of hydrogen fuel cell locomotives, in particular to a waste heat utilization device. The waste heat utilization device comprises a cooling pipeline, a power pump, a first distribution valve, a first radiator, a second radiator, a first temperature sensor and a controller, wherein the cooling pipeline penetrates through the hydrogen fuel cell; the inletend of the cooling pipeline is communicated with the power pump, and the outlet end is communicated with the inlet end of the first distribution valve; a first outlet end of the first distribution valve is communicated with an inlet end of the first radiator; an outlet end of the first radiator is communicated with an inlet end of the second radiator; the second outlet end of the first distribution valve communicates with the inlet end of the second radiator; the outlet end of the second radiator communicates with the power pump; the first temperature sensor is used for measuring a first temperature value in a cab; and the controller adjusts the flow of the cooling liquid distributed to the first radiator by the first distribution valve according to the measured first temperature value. According to the waste heat utilization device, the heat loss of the hydrogen fuel cell is reduced, and the hydrogen fuel consumption of the locomotive is also reduced.
