24V DC Cooling Fan bearing life

Changed the way ball bearing friction, rolling friction, this approach is more effective in reducing the friction between the bearing surface phenomenon, effectively increasing the "24V DC Cooling Fan" bearing life, and therefore the radiator longer life. The disadvantage is that the process brings more complex, resulting in cost increase, it also brings higher operating noise. "24V DC Cooling Fan" The main components are: AC motor. Its working principle is: "24V DC Cooling Fan" energized coil in a magnetic field by the force of the rotation. Form of energy is transformed: the main electrical energy into mechanical energy, and because the coil has a resistance, so that there is an inevitable part of the electrical energy to be converted into heat.
