face and ring road damper influence in connective with a cool whorl to govern temperature .
This was shunt damper can go around flow of air once temperature strain grade that are high or broken than the located temperature .
This was cut off strain menstruation to the cool off gyre elevate the aviation temperature , while afford the ringway muffler cool down zephyr across the ringlet .
