    2. Fluid Coupling Assembly


      1. A 3-stage linear temperature-controlled fluid coupling assembly is used. This fluid coupling assembly utilizes the characteristics of a bimetal to switch the fluid passages and appropriately control the silicon oil, in order to change the fan speed in three stages: off, middle, and high. The fan speed from middle to high is controlled linearly.
