The working principle of the cooling fan of the oxygen generator is realized by energy conversion, namely: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Its circuit principle is generally divided into various forms, and the performance of the fan will be different depending on the circuit used.
Three heat transfer methods for the cooling fan of the oxygen concentrator
1. Heat conduction, heat convection and heat radiation. The transfer of energy in matter itself or when matter comes into contact with matter is called heat conduction, which is the most common form of heat transfer. For example, the direct contact between the CPU heat sink base and the CPU to take away heat is thermal conduction.
2. Thermal convection: It refers to the heat transfer method in which the flowing fluid (gas or liquid) takes the heat away. In the cooling system of the computer case, the "forced thermal convection" cooling method in which the cooling fan drives the gas flow is more common.
3. Thermal radiation: It refers to the transfer of heat by means of ray radiation. The most common one is solar radiation in daily life. These three heat dissipation methods are not isolated. In daily heat transfer, these three heat dissipation methods all occur at the same time and work together.
Tips for cleaning the cooling fan of the oxygen concentrator
Since the cooling fan of the oxygen concentrator has not been cleaned for a long time, a lot of dust has been deposited outside. Do a simple cleaning of the outside of the fan first. Next, let's disassemble the cooling fan of the oxygen generator. There are two small screws on the cooling fan of the oxygen generator. Unscrew them, and the side near the air outlet will be loose. Gently break open the metal buckle of the cooling fan of the oxygen generator, and the cover on one side of the cooling fan of the oxygen generator can be opened. Be careful not to break the buckle too far to avoid loss of elasticity. tight. Turn on the cooling fan of the oxygen generator, the inside of the cooling fan of the oxygen generator is also terrible, all kinds of dense dust, especially the fan blades of the cooling fan of the oxygen generator, have accumulated a thick layer. After simply brushing the floating and sinking with a brush, I suggest that you wipe the fan blades carefully with a paper towel or cotton cloth dipped in water. It is best not to use some organic solvents, because it will easily cause the fan blades to be compatible with them, and bake at high temperature. It is easier to make the fan blades brittle and accelerate aging, and it is more reliable to use water. After careful and patient cleaning, the fan looks brand new. After adding a drop of lubricating oil to the central shaft of the fan, use the method of disassembly before and then reassemble it again. Even the fan part is cleaned up.
