In an internal combustion engine in which a cylinder is disposed substantially horizontally within a cylinder block and a water jacket is formed around the cylinder to be filled with primary cooling water, A box body filled with primary cooling water is provided on the outer circumferential side of the cylinder head which is fixed and has a combustion chamber formed on the inner circumferential side, and the heat generated by the secondary cooling water flowing above the combustion chamber in the box body is provided. An exchanger is disposed, and a lower communication port is formed on the lower side of the cylinder to communicate between the inside of the water jacket and the inside of the box, and on the upper side of the cylinder, the inside of the water jacket and the inside of the box are communicated with each other. A partition is provided that forms an upper communication port and partitions the inside of the box into an upper cooling side where the heat exchanger is disposed and a lower heat source side below the position where the upper communication port is opened, and The internal combustion engine is characterized by being provided with a drive unit that moves the partition body in a direction that increases a communication gap that communicates the upper cooling side and the lower heat source side as the temperature of the primary cooling water on the lower heat source side rises. Engine cooling system. 2. The cooling device for an internal combustion engine according to claim 1, further comprising a drive unit for moving the partition body in accordance with the temperature of the primary cooling water in the water jacket above the cylinder. 3. The cooling device for an internal combustion engine according to claim 1, further comprising a drive section made of a shape memory alloy.
