Generally speaking, the service life of a waterproof fan 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 lubricant in the oil-containing bearing, causing the device to shrink and increase friction, and the coil resistance will also increase, falling into a vicious cycle of heat generation and temperature rise.
The dust will make the quality of the fan blades change, increase friction, increase wind resistance, affect its own heat dissipation, block the heat sink and the air to stop heat exchange, generate static discharge and damage the components and equipment. The harsh operating environment may greatly reduce the effectiveness of the waterproof fan and greatly reduce the life span.
If the working pressure of the waterproof fan is high, the faster the fan speed will be, the faster the bearing will wear out, the more the stator winding coil and the electronic components will heat up, and the life will be relatively shortened.
We usually notice that the heat generated by the product is transferred to the heat sink and then blown by the cold air brought by the waterproof fan to take away the heat from the heat sink, and how much heat the waterproof fan can conduct The area 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 there is a certain prerequisite for this statement, that is, when there is enough remaining space in the case. If the computer case does not have a large heat dissipation space, if there is not enough free space, it is difficult to install a large heat sink in the case. Even if it can barely be installed in the case, a large contact area will block the heat sink. The surrounding hot air quickly dissipates, which causes the overall temperature inside the case to be too high, which affects the operating performance of the entire computer. Therefore, the editor recommends that the size of the heat sink area should match the case, and the area cannot be pursued by one person. .
