<p>PROBLEM TO BE SOLVED: To properly cool electrical components according to a temperature in a vehicle cabin, when cooling the electrical components by using air in the vehicle cabin.SOLUTION: An electrical component-cooling device 10 cools electrical components 20 provided at the outside of a vehicle cabin by using air in the vehicle cabin 30A, when temperatures of the electrical components 20 become a first predetermined temperature T1 or more. First of all, the device operates a cooling fan 104 temporarily and introduces the air in the vehicle cabin 30A in flow paths 202, 204, and determines whether or not a temperature of the air is less than a second predetermined temperature T2 that is lower than the first predetermined temperature. When the temperature of the air is less than the second predetermined temperature T2, the device continuously operates the cooling fan 104 and performs cooling of the electrical components 20. On the other hand, when the temperature of the air is not less than the second predetermined temperature T2, the device stops the operation of the cooling fan 104 and waits for a predetermined time.</p> |
