<p>A cooling device circulates cooling water through an engine main body (2) and a radiator (3) using an electric pump (1) and supplies cool air to the radiator (3) using an electric fan (4), thereby cooling the engine main body (2). During a dead soak period after an engine is shut off, a control unit (30) controls the operation states of the electric pump (1) and the electric fan (4) on the basis of cooling water temperature (THW) detected by a water temperature sensor (21), outside air temperature (THA) detected by an outside air temperature sensor (22), and battery voltage (GBA). Specifically, when the engine is shut off, if it is determined on the basis of the cooling water temperature (THW) and the outside air temperature (THA) that the engine is in a high temperature state, the control unit (30) controls the electric pump (1) and the electric fan (4).</p> |
