Fan clutch, temperature elements are dual metal spiral spring
WenQi feeling. Its working process:
(1) when the air temperature rise through the radiator, double the
metal thermal deformation, forcing WenQi valves open follower shaft
rotation, JinYou plate. Driven plate and the front cover of storage
and silicone oil flows between active plate and driven plate work
between cavity, clutch engagement, fan speed increases. Air
temperature is higher, JinYou open hole, fan speed is faster.
(2) when the air temperature drops through the radiator, dual metal
WenQi restorable, valves closed JinYou hole under the influence of
the centrifugal force, in the hole, silicone oil from the oil
chamber, working chamber returns the clutch, fan speed becomes very
low.
