I am engineering a new electronic 2 speed electric radiator fan controller and would appreciate some feedback and input from you guys. A while back I posted about an electronic systems monitor I am also working on and it is almost ready for beta testing. Now I am working on the fan controller. I could not find one on the market like I wanted so decided to engineer a new design and see if I could sell a few.
Right now it will control 2 fan speeds and has a couple of options. The options are the ability to alarm the engine temp and have an off delay to help keep down residual temp rise after the car is turned off.
Right now I have it programmed to run the low speed fan for 10 minutes if the engine rises above 185 after the car is turned off. If the car is running it cycles the low and high speeds to maintain around 185 degs. I can make the set-point adjustable to some extent.
Turn on low speed if A/C is turned on. Also thinking of adding an airflow sensor to turn off fans if car is moving enough to take care of A/C.
So my questions at the moment are what do you think about my general plan? And what about the ability to cool down the engine after turn off? And do you have any suggestions? Your input would be greatly appreciated. Could really use ideas concerning installation etc.
Thanks in advance.
