る請求項１記載の内燃機関の冷却装置。[Claims for Utility Model Registration] 1. A cylinder is disposed approximately horizontally within a cylinder block, and a block water jacket filled with primary cooling water is formed around the cylinder, and is fixed to the top side of the cylinder block. In an internal combustion engine, a head water jacket is formed in the cylinder head filled with primary cooling water, and the head water jacket and the block water jacket communicate with each other through a communication port. A heat exchanger through which secondary cooling water flows is disposed within the expansion part, one end communicating with the head water jacket and the other end communicating with the head water jacket. A communication passage communicating with the expansion part is formed in the cylinder head at a position adjacent to the heat exchanger, a large number of fins are formed on the outer peripheral surface of the cylinder head, and a plurality of fins are formed at the end of the crankshaft of the internal combustion engine. A cooling device for an internal combustion engine, characterized in that a fan is connected to the fin, and a ventilation passage is provided between the fan and the fin. 2. The cooling device for an internal combustion engine according to claim 1, wherein the height of the fins increases as the fins move upward along the cylinder head.
