Abstract

The invention provides a cooling structure of a cylinder head. The cooling structure of cylinder head comprises a main water channel arranged in a cylinder head, a first water jacket, a second water jacket, a nose bridge area, a first water inlet hole, a second water inlet hole and a guide block. The first water jacket and the second water jacket are separated by a partition plate, the first waterinlet hole is formed in the top end of the main water channel, the first water jacket is communicated with the main water channel through the first water inlet hole, the second water inlet hole is arranged below the first water inlet hole, the second water jacket is communicated with the main water channel through the second water inlet hole, and the nose bridge area is arranged in the second water jacket. According to the cooling structure of the cylinder head, layered independent cooling can satisfy the cooling of each high-temperature area of the engine, and the layered independent coolingeffect can greatly improve the cooling capacity of the whole engine.

Description

technical field [0001] The invention belongs to the technical field of cylinder head cooling, and in particular relates to a cylinder head 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 pa...
