The existing computer power supply cooling fan , one way is to use sliding bearings, the other way is to use ball bearings. The cooling fan of computer power supply with sliding bearing is short of oil due to long-term use.Because there is no oiling device, it is easy to generate noise, or the fan is stuck, which causes the heat generated by the electronic devices in the power supply cannot be distributed in time to burn out the electronic devices in the power supply.The cooling fan of computer power supply with ball bearing is fully sealed and has high cost.After the ball is worn, the noise is large, and the ball debris may jam the bearing, causing the heat generated by the electronic devices in the power supply when working to not be distributed in time and burn out the electronic devices in the power supply.

Taiwan's San Ju motor cooling fan manufacturers have found a kind of oil-lubricated computer power supply fan data (from the network), aiming to provide an oil-lubricated computer power supply fan with good lubrication performance, low cost and long service life, which can be lubricated without removing the fan. It consists of an oil filling plug (1) and a fan (2), wherein the oil filling plug (1) arranged at the tail part of the fan (2) is formed by a high-elasticity rubber plastic body, the oil filling plug center is provided with an oil filling hole (4), an oil storage groove (5) is arranged in an inner hole extending into the tail hole part of the fan, and the oil filling plug tail part is provided with a large round step (7). The scheme data can be used in various desktop computer power fans.
