PURPOSE:To protect electronic parts by connecting a ventilation fan to a thermal generator for generating power from residual heat of engine and supplying power to the ventilation fan upon stoppage of engine thereby suppressing temperature rise in an electronic parts containing box after stoppage of engine. CONSTITUTION:A thermal generator 6 arranged with P type and N type thermal generating elements alternatively and radially is fixed in an exhaust manifold 5 of engine 2 in an engine room. Ventilation fans 4a, 4b are provided at the lower portion of engine room 1 and connected to the thermal generator 6, where upon turning off of ignition key the ventilation fans 4a, 4b are supplied with power to prevent temperature rise in electronic parts containing boxes 12a, 12b. |
