Abstract

The invention provides a machine body cooling structure. The machine body cooling structure comprises an air cylinder cover, a water feeding channel, a first water jacket, a cylinder barrel, a water outlet main pipe, a first water inlet hole and a water outlet hole, wherein the water feeding channel, the first water jacket, the cylinder barrel, the water outlet main pipe, the first water inlet hole and the water outlet hole are arranged in the air cylinder cover. The first water jacket is arranged at the bottom end of the water feeding channel, communicates with the water feeding channel through the first water inlet hole, and also communicates with the water outlet main pipe through the water outlet hole. By means of the machine body cooling structure, the cooling of each high-temperature area of an engine can be met by layered independent cooling, and the cooling capacity of the whole engine can be greatly improved through the layered independent cooling effect.

Description

technical field [0001] The invention belongs to the technical field of cylinder head cooling, and in particular relates to a body cooling structure. Background technique [0002] The cooling water flow scheme of the engine in the prior art is to send water to the upper part of the cylinder barrel first, and then flow out through the cylinder head, and there is no forced water flow in the lower part of the cylinder barrel. Cooling water with a lower temperature is sent from the front end of the cylinder to the water jacket on one side of the cylinder, and then the main water flow flows through the gap between the cylinders to the other side of the cylinder, and passes through the gap between the cylinder and the cylinder head. The water holes flow upward into the cylinder head, then flow through the high-temperature area near the center of each cylinder, and finally flow out through the outlet pipe of the cylinder head. [0003] For example, the Chinese invention patent appl...
