Q: What is the "no-load drag torque" of a fan clutch? How does it specifically affect fuel consumption?
A: No-load drag torque is the minimum torque required to drive the clutch when it is fully disengaged. The lower this value, the more significant the fuel savings. High-quality clutches optimize bearing design and silicone fluid return channels to keep this value very low (e.g., <0.5 N·m), maximizing energy savings when disengaged.

Q: How is the "preload" of the bimetallic spring set? How does it affect the engagement characteristics?
A: The preload is set mechanically by the initial bend angle of the spring during installation. It determines the initial thermal energy threshold required to trigger valve action. Increasing preload raises the engagement temperature, and vice versa. Precisely setting the preload is a core process for calibrating the clutch's operating temperature window, ensuring it exactly matches the engine's thermal management strategy.

Q: Will the silicone fluid undergo "viscosity degradation" under long-term shear? How is this addressed?
A: Yes, this is an aging phenomenon of silicone fluid called shear thinning. High-performance clutches use specially formulated high-shear-stability silicone fluid whose molecular chain structure resists permanent viscosity loss due to prolonged shear. Additionally, optimized flow passage design reduces turbulence and local hot spots, systematically delaying fluid aging.

Q: What is "thermal creep"? What challenge does it pose to the clutch's sealing performance?
A: Thermal creep refers to the slow plastic deformation of sealing material under high temperature and constant pressure. This can lead to a loss of lip pressure and eventually cause leakage. The countermeasure is to use high-performance rubber materials with excellent anti-creep properties (e.g., FKM) or PTFE seals, and to control the operating temperature and pressure of the seal through design.
