Can a Toriod transformer be Glued to a heat sink??? The Toroid
will be JB welded to the heat sink.

The toroid will be wound with a 30 degree gap between the start of
the winding to the end of the windings the toroid will ( winding
gap) be glued at that that point vertical position the windings
will be about 1/4 inch above the heat sink.

Comments???

Thanks!!!

Is the toroid getting so hot that RTV will not work? If so, then you
have other problems. Toroids are not supposed to get hot! Most toroids
are attached to circuit boards with RTV. I have never seen one needing
a heat sink.

JB Weld is wonderful stuff, but will crack if subjected to stress or
vibration. If you still want to go ahead with this, you need to make a
rough surface on the toroid and the heat sink to give the JB Weld a
place to attach to.
