This new design can obviously improve oil stream and Distribution of temperature rise in Liu You areas, and the oil stream Distribution of temperature rise in Liu You areas is equal
Even, oil duct declines without stagnant thermal phenomenon, oil stream speedup temperature rise, and few with oil.
Because such as oil duct height is bigger, velocity flow profile is more uneven between horizontal oil duct in oily area, and unfavorable shadow is produced to temperature rise
Ring.
And if inner-outer coil longitudinal direction oil duct width is identical, then longitudinal oil duct section of exterior loop is much larger than interior loop, make
Interior loop is much smaller than into outside line astragal cake area internal resistance so that most of oil pours off from exterior loop, and interior lines coil temperature rise is higher.
