Topic: miner heat (Read 1659 times)

This is so creative idea, heating a water with miner heat.
I also did this kind of thing, using my laptop to ironing a blanket.

In the case of boiling I can only imagine that Spoondoolies units are capable of reaching boiling temperature, the Spoondoolies ASICs can run at above 100C. It would be an interesting project to use water evaporation to cool ASICs.

As I don't know the prices in Brazil I couldn't guess what would be the roi nor do I have the experience for operating miners in hot climates.

Electric prices are low here in Iceland about $0.074 er kWh on the site where the picture is taken. The miners are over a year old, they made roi long time ago. The miners still net a profit and give about $0.102 per kWh used, which gives a profit of $0.028 per kWh per hour. That is about $250 per annum or $20.44 per month. It's not a whooping amount but it's essentially free heating in a cold, horrid and desolate place.

The miner heat is currently used to heat up the shed, that's about it. The only realistic use I can find for miners beyond profit.

He is not asking how to dissipate heat. He wants to actually use the heat to boil water for cooking, for example.
First, you are aware this miner will not get you more than a few dollars per quarter, right? If electricity price is also added your roi is negative or close to that as energy price in Brazil is very expensive

You are asking about thermodynamics energy. I don't think you will have much use to that with a single miner. Perhaps with several dozens of them you could start thinking on funneling their heat or something like that.

Thank you, fabricated it from scratch by myself. CNC'ed from 4mm aluminum plates and sandwiched together and has a total width of 7 mm, I want to have 5 mm in total for experiments on the S5 when I get around to designing it.

It was an experimental project for fun with a (actual) farmer I know, we've so far mixed standard house heating with mining.

CAD designs are already done for Avalon 4 and Antminer S5 is next in row, current design goal is have cooling plates running at house circulation pressures. This would put it in the 2-3 bar pressure range and would be heaps of fun to do. A part of the engineering would be dumpload controls that make sure the circulation maintains a set temperature, right now we let the radiators naturally release the heat into the room. This limits thermal emissions to fairly low numbers, I've had to underclock the miners so they don't surpass the thermal emission capacity of the radiators.


The parts are aluminum plates that are easy to get but the hard part was access to a fabrication site, if you are in pinch you can simply get a Chinese CNC rapid developer to fabricate the parts. Provided you have the CAD drawings ready and willing to pay a reasonable fee.

There are heat sinks placed on the chips, they aren't shown in the image. The Avalon 3 design actually transfers most of the thermal energy through the bottom of the PCB board, if you look under the PCB you can see the solder forming a solid thermal conduction block. The Avalon 3 stock cooling reflects this but I would prefer to water cool both sides as well. So far I've had Avalon3 running at around 30-40C, it mostly depends on temperature of the coolant, Avalon 3 can run smoothly at 50C.

I found it very interesting what you did.
But I do not think to do the same because it is difficult to find specific pieces in my state.
Also, the blade is a little sloppy, in my opinion, because the sink is not in contact with the chips. So the heat must cross the board ...

Achei muito interessante o que você fez.
Mas acho que não pra fazer igual porque é difícil encontrar peças específicas em meus estado.
E também, a blade é um pouco mal feita, na minha opinião, porque o dissipador não fica em contato com os chips. Então o calor tem que atravessar a placa...

You make the water cooing system yourself ?? that really nice. 

If you live in a cold area, or when it gets cold, you can put a couple fans in front of the heatsinks to vent the air into a room to heat it up. You might also be able to find a way to vent it directly into your heating system (if you use central air) and have that circulate around the house.

Some old avalon3 miners that are water cooled, you can see little green lights hiding in the makeshift shelves.

The miners are hooked up to a heat exchanger and feed the radiators for the shed.

I have a block erupter blade that mining at 10,7ghs.
I always measure his temperature with an infrared thermometer and measures around 158 degrees
I wanted your opinions on how I can do to take advantage of this heat to heat water for example

eu tenho uma block erupter blade que minera à 10,7ghs.
eu sempre meço a temperatura dele com um termômetro infravermelho e mede em torno de 70 graus.
eu queria a opinião de vocês de como que posso fazer pra aproveitar esse calor aquecer água por exemplo
