Title:
VEHICLE COOLING SYSTEM
Document Type and Number:
Japanese Patent JP2023128673
Kind Code:
A
Abstract:
To provide a vehicle cooling system capable of enhancing an increase in a temperature of a transmission when a temperature of transmission oil is increased and enhancing a decrease in the temperature of the transmission when the temperature of the transmission oil is decreased.SOLUTION: A vehicle cooling system comprises: an exit side cooling water supply passage 24 which branches from a feed passage 21A; an entrance side cooling water supply passage 25 which branches from a position close to an upstream side of a cooling water inlet 2A in a return passage 21B; and a flow passage switch valve 41 which can switch between the exit side cooling water supply passage 24 and the entrance side cooling water supply passage 25 so as to allow cooling water either therein to flow into an oil cooler 4A. A control section 10 controls the flow passage switch valve 41 on the basis of comparison results between a temperature of the cooling water and a predetermined water temperature TWc and between a temperature of transmission oil and a predetermined oil temperature TOc.SELECTED DRAWING: Figure 1
