Claims

[Scope of utility model registration request]

a first cooling fan for engine cooling;
a first electric drive means for driving a cooling fan;
Engine room cooling control comprising a second cooling fan installed in the engine room, a second electric drive means for driving the second cooling fan, and an engine temperature detection means for detecting the temperature of the engine. In the apparatus, when the engine temperature value detected by the engine temperature detection means is greater than or equal to a first predetermined value and less than a second predetermined value, the first cooling fan is driven at a low speed; When the value is greater than or equal to the third predetermined value and less than a third predetermined value, the first cooling fan is driven at high speed, and when the value is greater than or equal to the third predetermined value, the first cooling fan is driven at high speed and the second cooling fan is driven. An engine room cooling control device comprising: control means for controlling the first and second electric drive means so as to drive the first and second electric drive means.
