    Oil Cooling Dummy Load with Radiator

    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.

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

    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?
