The invention discloses a split cross-flow reverse-flow type cooling device for a gasoline engine, and belongs to the technical field of engine cooling. The liquid supplementing kettle is communicated with the cylinder cover water jacket through the degassing pipeline, the degassing pipeline is further communicated with the radiator, the water outlet pipe is communicated with the radiator, the water outlet pipe is communicated with the cylinder body water jacket and provided with the thermostat, the thermostat is arranged on the air inlet side of the cylinder body water jacket, the cylinder body water jacket is connected with the cylinder cover water jacket, and the cylinder body water jacket is provided with a drainage channel and communicated with the cylinder cover water jacket. A water inlet of the water pump is communicated with the radiator, a water outlet of the water pump is communicated with the cylinder cover water jacket, and oil cooler inlet return water and EGR cooler inlet return water are respectively connected with corresponding ports of the water pump. According to the integrated cooling system, exhaust side water inlet, reverse flow cooling, cross flow cooling, cylinder body and cylinder cover split cooling and cylinder cover layered cooling are designed in an integrated mode, cooling liquid water inlet is reasonably arranged, the flow of all the positions needing to be cooled is accurately distributed according to requirements, efficient, uniform and accurate cooling is finally achieved, and design support is provided for actual engineering application.
