Category: immersion cooling

It was a long way, but finally we did it!

Here is the video:

Miners are working inside. There is the first benefit: Antminer S9 13,5T working 15T

Finally I fixed cold trap by changing thermal elements

I can proceed the start up process.

Hello everyone!

We haven’t posted anything for a long time, because of a problem that forced us to invent solutions.

Everything was good. We installed everything in the Cool Tank and run last tests before adding liquid freon. We noticed that cold trap temperature raised too high up to 50+C.

Why this could happen?

Previously we noticed that pump was working a little bit noisy. The reason for noise was air in pipes. While we were fighting with air bubbles removal from water flow, cold trap cooling wasn’t effective enough and we got over heat.

Thermal elements inside cold trap melted. So we lost it. It was unique item made per our specifications with serial number 000001.

So now we fixed circulation problem by removing all obstacles from cold trap piping

Also added water meter to be sure, that we have circulation and to measure pump flow rate.

New piping around cold trap

And finally we tested the last survived thermal element. If we have efficient circulation able to remove heat, we should have temperature below zero on the other side of thermal element.

Let’s see:

Everything is ok now. That’s what we need from cold trap.

So, now we have to wait for replacement of thermal elements, assemble cold trap and proceed with start up on the next week.

To be continuing…

We are running different tests

It’s time to put mining hashing boards to CoolTank
