機関の冷却装置。[Claims for Utility Model Registration] 1. In an internal combustion engine in which a cylinder is arranged substantially horizontally within a cylinder block, a block water jacket filled with primary cooling water is formed in the cylinder block, and the jacket is tightened and fixed to the cylinder block. A head part water jacket is formed in the cylinder head which is filled with primary cooling water, and an extension part which is communicated with the block part water jacket and is filled with primary cooling water is provided above the cylinder, and inside this extension part. A heat exchanger through which secondary cooling water flows is disposed in the head, a first communication port communicating between the inside of the head water jacket and the expansion part is formed at a position adjacent to the heat exchanger, and the head A cooling device for an internal combustion engine, characterized in that a second communication port communicating between the inside of the water jacket and the inside of the block water jacket is formed below the cylinder. 2. Claim 1, characterized in that a communication path is formed between the head water jacket and the first communication port, and the cross-sectional area of this communication path is gradually narrowed toward the first communication port. Cooling device for the internal combustion engine described.
