The invention relates to the technical field of cooling devices, in particular to a rapid cooling device for auto spare parts. The rapid cooling device comprises a bottom plate, a high-pressure tank and a liquid outlet device, wherein an outer box body is arranged above the bottom plate through a support, a heat preservation pipe is arranged inside the outer box body, a heat preservation cavity isformed between the heat preservation pipe and the outer box body, a bearing is arranged in the middle of the bottom end of the outer box body, a motor is installed below the bearing, the upper end ofa rotating shaft of the motor penetrates through the bearing to extend into the interior of the heat preservation pipe, and a rotatable workbench and the like are installed at the upper end of the rotating shaft of the motor. According to the rapid cooling device for the auto spare parts, the structure is convenient to assemble, moreover, the structure is stable, liquid nitrogen or carbon dioxideis conveyed to air jetting heads through the liquid outlet device and is jetted out from the air jetting heads in a gaseous mode, due to the fact that a large amount of heat can be absorbed when a liquid is vaporized, the high-temperature auto spare parts can be quickly cooled through the gas jetted out from the air jetting heads, the motor drives the workbench to rotate, so that the auto spare parts are uniformly cooled, and meanwhile, the cooling efficiency is improved.
