Automotive electronics related principle of automobile electronic fan for car driving is normal play an irreplaceable role, so for the electronic fan related maintenance concept will have a certain understanding, not only convenient to yourself daily check, for general troubleshooting is also has a lot of help. Mentioned about the electronic fan part of the working principle, more knowledge about this aspect, we went on to get to know. Say to the air conditioning condensers and water tank, because the two parts are get together, so the electronic fan for cooling water tank of cooling time, also want to consider the condenser. Said although the car air conditioning a relatively independent system, but also a divergence of heat source, so the open and close of air conditioning is also affect the performance of the electric fan, if does not take into account in the related concepts of electronic fan to this piece of words, is to check the maintenance work in the late. When the electronic fan need to work, there will be a special thermal switch will related to thermal signals to control the electronic fan work related units, and according to the different cooling needs, to choose different startup speed, so the whole electronic fan can very good coordination, for cooling the related work. Automotive electronic fan manufacturer in addition, electronic fan also through resistance in series or not to implement the actual work required to different high and low speed, so as to better to work for gas car for heat dissipation.
