<p>PROBLEM TO BE SOLVED: To provide an engine cooling device capable of reducing a size of an engine.SOLUTION: In an engine cooling device, a vibration power generation element device 2 is attached to an engine vibrating section 1, a thermoelectric element device 3 is electrically connected to the vibration power generation element device 2 and the thermoelectric element device 3 is fixed to an intake air passage wall 4. Thus, the engine cooling device is configured to allow: the vibration power generation element device 2 to generate electric power with vibration of an engine; and the thermoelectric element device 3 to absorb heat from the intake air passage wall 4 with the electric power generated by the vibration power generation element device 2. A plate-like power generation cooling device 5 integrating the vibration power generation element device 2 and the thermoelectric element device 3 is fixed to the intake air passage wall 4. The power generation cooling device 5 is also fixed to an oil pan wall 6.</p> |
