COOLING MEDIUM CIRCULATION APPARATUS FOR VEHICLE

A cooling medium circulation apparatus for a vehicle includes: a housing having a valve mounting device with an internal space and a plurality of ports connected to a plurality of thermal management components; and a valve body rotatably mounted in the valve mounting device, partitioned into a plurality of layers vertically, with a plurality of flow paths formed in each layer, and with a plurality of circulation holes formed on outer sides corresponding to each of the flow paths and selectively matching the ports, the circulation holes elongated vertically to have a height greater than a height of the flow paths. The cooling medium circulation apparatus may be installed in the vehicle in a compact manner, while eliminating the need for multiple peripheral pipes, and facilitating the circulation of coolant across various cooling system components.
