Double 6-way valve for vehicle cooling system

A double 6-way valve for a vehicle cooling system, the double 6-way valve comprising:

• an upper housing including a plurality of upper nipples disposed at equal intervals on an outer circumference surface thereof, wherein the plurality of upper nipples is coupled to and supported by first parts of the cooling system;
• a lower housing stacked under the upper housing and including a plurality of lower nipples disposed at equal intervals on an outer circumference surface thereof, wherein the plurality of lower nipples is coupled to and supported by second parts of the cooling system;
• an upper hub rotatably mounted within the upper housing;
• a plurality of upper flow channels independently provided within the upper hub and each coupled to two upper nipples, among the plurality of upper nipples, selected based on a rotation angle of the upper hub, such that a coolant flows through each upper flow channel of the plurality of upper flow channels;
• a lower hub rotatably mounted within the lower housing and stacked under the upper hub;
• a plurality of lower flow channels independently provided within the lower hub and each coupled to two lower nipples, among the plurality of lower nipples, selected based on a rotation angle of the lower hub, such that the coolant flows through each lower flow channel of the plurality of lower flow channels;
• and
• a driving apparatus configured to rotate the upper hub and the lower hub.
