Fan cooled dummy load

**chy_farm** · Apr 6, 2018, 01:17 AM

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 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?

Thank you very much Sir, PJs or Mr. wizard. I love to see your avatar which reminds me of an American novelist Ursula Kroeber Le Guin and her work 'A Wizard of Earthsea'.

As far the oil, I used seed oil for environmental purposes, but it was only for my personal use. In fact I put a caution note at the cover telling 'Use qualified transformer oil'.
The purpose was to know how electromagnetic waves e.g. one from electric blanket gives influences to human body. For example the commercial power line emits electromagnetic waves, 50Hz or 60Hz here, and this wave gives electric vibration to our body. We can detect this influence when we see our body with a precision current detector and oscilloscope connected to it.

After giving such external loads to the body, can we see any evidence of medical stresses in body? that was our study. I knew that sort of this study was done some decades before we have tried, but the method of ours was a tad different to the past examples. We tried to detect the body in a holistic manner, by detecting the subtle signals given from many and specific spots on the skin of the body.

Glad to know you were interested in this, thanks.

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

**chy_farm** · Apr 6, 2018, 08:39 PM

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** · Apr 6, 2018, 09:30 PM

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

Thank you for the quick response, Chy. Glad you enjoy my avatar and appreciate the reference to 'A Wizard of Earthsea', which may have a somewhat personal correlation to Ged's journey or perhaps Perceval...I get confused sometimes with CRS (can't remember stuff).

The avatar goes way back for me (5+ decades) and forward to now in that I use the words, "Engineer by Trade, Alchemist at heart" when ask to describe myself...with no dichotomy, in my mind anyway, about it.

I found it interesting that your system used oil cooling (high end & efficient) and just curious about the type. It's well thought out & shop built with cheap and cheerful components. A good fit for HMT, IMHO. Your use of seed oil instead of Xformer oil is an inexpensive, handy and smart choice!

A very interesting experiment and assume you used some sort of GSR's to measure responses. By your words I take it you wrote some sort of paper on it? I also take for granted that the dummy load was for the controlling the source. When I first saw your post I thought it might be for Off Grid dummy loads, which I am also interested in pursuing some regenerative system for them. Then I saw your second post below and was intrigued even more.

I have been interested in lots of testing protocols and efficacy testing around this and many other things, like Red/blue light (405nm) retinal stimulation, sound stimulation (VLF to 600khz) and pulse magnetic wave generators. Even had a conversation with Dr. Emoto and his son at a conference in SF a year or so after his book came out, about such things. Basically I am pretty eclectic in my pursuits and always look for that balance in science and alchemy toward some truth.

Thank you for the great post's so far...I now want an expansion chamber on my chainsaw! Keep em coming.
