It won't hurt the electrical components, and might do some good. If it comes out cold when it's turned upside down I doubt that its just compressed air . There is probably some propellant in it like propane of Freon 113. Neither one of these would hurt the electrical components either. Expanding air tends to cool, but it wouldn't make any difference if the can was upside down or not. Check the label, if there's propane in it be careful around those hot parts.
I would not do it.Blowing extremely cold air on extremely hot metal results in fractures and breakage in components. Same as if you dunked it in water. Plus, I do not know how effective this would be in cooling the whole assembly vs. just the surface.If you need extra cooling, then install a 12V muffin fan or something along that line to blow cool air across everything while it is operating and leave it on after the pull to get a gradual cool down.
I agree that it is a bad Idea for the following reason: The thermal switch is attempting to protect the windings on the motor. By cooling the switch you are fooling it into feeding more amps into the hot windings. When they reach the right temp the insulation will fail and you will be looking for a new winch. Joe
most thermal switches ive seen are internal--so you cant blow or soak them with anything---ive got a gas pump i use to pump veg oil--if hot enough--it will shut down--but i just put cold rags around the outside---and in a mite--itll take off again---the thermal inside it is in far enough--then when the contacts close--all the windings are cooled off---
QuoteThe thermal switch is attempting to protect the windings on the motor.I guess that is the question I should have asked. :-[ I'm sure if this was a feasible idea one of you guy's would have come up with it earlier than me.QuoteWhen they reach the right temp the insulation will fail and you will be looking for a new winch. JoeThat's not such a bad idea. :D
When my wench gets hot, there's really nothing I can do to cool 'er down; anything I do just makes it worse; best to just back off and let 'er cool down naturally. ;D
