Radiators mainly rely on convection. If the convection is destroyed, the thermal efficiency will be greatly reduced.
Oil-containing bearings are sleeve bearings that use sliding friction and use lubricating oil as a lubricant and drag reducer. When used initially, the operating noise is low and the manufacturing cost is low. However, the wear and tear of this kind of bearing is serious, and the life span is far behind that of ball bearings. Moreover, when this kind of bearing is used for a long time, due to the oil seal (computer radiator products cannot use high-end oil seals, which are generally ordinary paper oil seals), the lubricating oil will gradually evaporate and dust will enter the bearing, causing the fan speed to slow down and the noise to increase. In serious cases, the fan may eccentrically vibrate due to bearing wear.
The radiator is not immune to the dust. Due to the wind flow, the wind pressure generated by the radiator fins is not pressed down vertically but spreads in an annular shape. This is just like a ceiling fan on the roof of your home. The air flow directly under the fan is often not as strong as the periphery of the ceiling fan. Similarly, the dust in the air will circulate around the periphery with the wind speed and adhere to the cooling fins around the fan, causing air flow to be blocked. At the same time, the return air caused by the blockage of the fins will draw a large amount of dust into the fan blades and reduce the use of the radiator. Lifespan; water vapor in the air adheres to the fan blades, causing dust to adhere to the fan blades, increasing the weight of the blades and reducing the speed [small crane]; the radiator bearing rotates at high speed, and as time goes by, oily substances overflow from the bearing and stick to the radiator, accumulating more dust.
The speed of the radiator fan is determined by the number of turns of the coil in the motor, the operating voltage, the number of fan leaves, inclination angle, height, diameter and bearing system. When the fan structure is fixed, the rotation speed of the DC fan (that is, the fan using DC power) changes synchronously with the change of the operating voltage. The fan's speed can be measured through the internal speed signal or externally. The external measurement uses other instruments to see how fast the fan rotates. The internal measurement can be viewed directly in B or through software. The internal measurement error is relatively large.
