Generally speaking, the service life of waterproof fans will be affected by the operating environment and working pressure. If the waterproof fan works in a high temperature working environment, it will accelerate the volatilization of the lubricating fluid in the oil-impregnated bearing, which will cause the device to shrink and increase the friction, and the coil resistance will also increase, falling into a vicious circle of heat generation and temperature increase.
The dust will change the quality of the fan blade, increase friction, increase wind resistance, affect its own heat dissipation, prevent heat exchange between the heat sink and the air, and cause electrostatic discharge to damage components and equipment. The harsh operating environment may greatly reduce the effect of the waterproof fan, and greatly reduce the lifespan.
And if the working pressure of the waterproof fan is high, the faster the fan rotates, the faster the bearing wears, the more the stator winding coil and the electronic components heat up, and the lifespan is relatively shortened.
We usually notice that because the heat generated by the product is conducted to the heat sink, and then is blown away by the cold air brought by the waterproof fan, the heat of the heat sink is taken away, and the amount of heat that the waterproof fan can conduct is similar to The size of the heat sink is related.
Generally speaking, the larger the contact area between the heat sink and the air, the better the heat dissipation effect of the waterproof fan, but this statement has a certain premise, that is, there is enough remaining space in the chassis. If the chassis of the computer does not have much space for heat dissipation, if there is not enough remaining space, it is difficult to install the heat sink with a large area into the chassis. Even if it can barely be installed in the chassis, the large contact area will block the heat sink. The hot air around it dissipates quickly, which causes the overall temperature inside the chassis to be too high, which affects the performance of the entire computer. Therefore, we recommend that the size of the heat sink area should match the chassis.
