The invention belongs to the technical field of fire-fighting sprayers, and discloses a sprayer for thermal runaway cooling of a lithium battery pack of an electric vehicle. The spray head for thermal runaway cooling of the lithium battery pack of the electric vehicle comprises a threaded main pipe, an inner pipe is connected in the threaded main pipe in a sleeved mode, and a spraying mechanism is arranged at the top end of the inner pipe; the spraying mechanism comprises an outer ring, an inner ring and an inner ring, wherein the outer ring is fixedly connected to the top end of the inner pipe; the top cover is arranged at the top end of the outer ring and seals the top opening of the outer ring; the spraying main pipe assembly is arranged on the top cover; and the plurality of spraying branch pipe assemblies are also arranged on the top cover. According to the spray head for thermal runaway cooling of the lithium battery pack of the electric vehicle, three or four spray heads are arranged in a single row to form a thermal runaway bottom spray assembly of the lithium battery pack of the electric vehicle, and full-coverage cooling control can be performed on the lithium battery pack, so that rescue workers can temporarily and quickly access the bottom spray assembly at a chassis of the electric vehicle on site; and the device is also suitable for fixed installation in centralized parking places of electric vehicles.
