Fan cooled dummy load

[chy_farm]

Made a dummy load with cooling fun.

A dummy load is ; https://en.wikipedia.org/wiki/Dummy_load


She has a circulation unit for the cooling oil, this is the speed controller.

At the back a fan is built in next to the radiator.

I got a nice radiator from a junk yard in the vicinity.

It was fortunate to me that I got a new-old-stock trochoid oil pump, but it seems to be a tad over-killing.


I made several types of load, this one shown below is of 50ohms, a standard type.

Not yet calculated the capacity, but I suppose this can withstand more than 3kw.

Incidentally this dummy load was used in a study to detect subtle reactions from human body when it gets some certain amount of electromagnetic waves.

Nicely done cooler. And I like your load. Nichrome wire?

[chy_farm]

Hello,@mwmkravchenko thanks for comment. Yes it's nichrome wire.

And it's wrapped around on a mica plate.

Nice. The other possibility is a ceramic tile. You will have a great amount of cooling capability with your setup.

[chy_farm]

That will be also fine Mwmkravchenko, ceramic one may last longer in higher amperage.

Nice build Sir! I'd like to know more of how this is used in a detector circuit if you are willing. 3kw seems quite high for a system like that. Also what kind of oil are you using?
