Means and Actions for Solving the Problems A fan for rotating an engine which outputs energy with exhaust gas and generating a flow of air by rotating on a rotation axis, and a cooling fluid for cooling the engine are An engine cooling device having a heat exchanger through which an air flow passing through an inside and generated by a fan passes through the outside and performing heat exchange between a cooling fluid and a flow of the atmosphere,
At least one of the fan and the heat exchanger is rotatably supported, and exhaust from the engine rotates at least one of the fan and the heat exchanger. Either the fan or the heat exchanger, or both the fan and the heat exchanger, are rotatably supported, and the exhaust gas from the engine rotates either the fan or the heat exchanger or both the fan and the heat exchanger. Therefore, the kinetic energy of the exhaust gas exhausted from the engine is used to promote heat exchange between the cooling fluid and the air in the heat exchanger, without lowering the output of the engine,
Heat exchange between the cooling fluid and air in the heat exchanger is promoted.

If the heat exchanger has a cylindrical or arc shape surrounding the rotation axis of the fan, the vortex flow generated by the fan traveling along the rotation axis as a whole is a cylindrical or arc heat exchanger. And collide with each other almost uniformly. Therefore, a relatively large amount of the air flow generated by the fan passes through a part of the heat exchanger, but almost no air flow generated by the fan passes through the part of the heat exchanger, and the cooling efficiency of the cooling water is low as a whole. According to the present invention, the cooling water can be efficiently cooled in the entire heat exchanger, as compared with the heat exchange device of the prior art.
