1  Bitcoin / Hardware / Re: Heat evacuator through window for 12 asics on: April 26, 2019, 10:34:12 PM
The question of putting a fan to complete the flow of output is left to the final customer. In the closet the dimensions of the air ducts are generous so that it does not affect the temperature of the asic (as I have said before) I did it so I can not offer a two year warranty to a fan that will work 7 / 24, I also thought that it was a danger that this big output fan would stop working putting at risk of overheating the Asic. If the customer decides to put the fan, it could "double" the capacity to put Asic in the cabinet, for example, if the ventilation is efficient, 12 "double tube" Asic (s15, z9, z11 ...). If I find the right economic conditions, I will carry out the soundproof design that I have in mind. The problem with this design is that it requires a previous module (to the Asics) and another module later so that the sound is reduced. In total it would measure 30 cm (sound reducer at the entrance of the Asics module) + 45 cm (asic module with insulation) + 60 cm (module with insulation with interior panels) + 60 cm (same as the previous one) +80 cm (driving towards window with insulation) = 275 cm (it would occupy 195cm in the room once placed in the window). This thought well not to make much noise in the room where it will be and also to not make noise in the street that will receive the hot air.
It is a project a bit expensive and results are not too clear.

I think I'm going to start with something a little smaller.

Thank you for your interest.

This is the box I made for the D3 that I told you about. I made a series of 10 and another of 15 boxes. I just have to sell 5. I did a back filter and another front to take advantage of the heat in winter. Removing the filters is ready to connect 16cm tubes to be able to conduct hot air through a window. I have also sold them for S9 and for T2T. The customers were quite satisfied. Now I'm designing a box that admits two "single tube" asic and double fan (in and out) or one of "double tube" and also double fan by tube (S17, A9 Zmaster, GMO B3 ...). The question I have when I think of how many "single tube" asic and a single fan would be able to introduce in that design (z9 mini, Avalon 741, ...), the same doubt I have with "double tube" and 1 fan for each tube (Z11, E3, Avalon 10, S15, S11, DR5 ...). When you do not physically have the Asic equipment to test, it is a big problem because you want to commit as few faults as possible. The choice of the diameter of the outlet duct is the most important. Soundproofing anyone does ... but getting the equipment is not hot is the most difficult, especially here in Spain 30š centigrade for 5 or 6 months a year. It forces you to oversize ducts and to expel air outside.

That is why I give so much importance to knowing what "real" flow of air has.

3  Alternate cryptocurrencies / Mining (Altcoins) / Idea: Creation of "real" air flow table of ASIC models. For soundproof desing. on: April 21, 2019, 09:29:10 PM
Good afternoon.

I think it is important to make a table of real air flows (m3 / h or cfm) of each model of Asic (air-cooled) that we know. In this way we will be able to manufacture more efficiently our soundproof boxes for Asic.

The "real" flow (at maximum regime) of refrigeration nobody knows, and I tell you why.

The first thing we think is that it would be enough to look at the reference of the fan of that Asic that the manufacturer gives us and see what air evacuation data gives us. But this is not enough, it is a data for nothing reliable ... we must count on the resistance of the heatsinks and internal plates (of different sizes and configuration in each manufacturer and model) that directly reduce the flow. And there are more variables ... equipment with a only fan, there are with double fan, there are fan with 5000 rpm other with 6000 rpm or 7500 rpm, also equipment with fan input different from the output, ... and single-tube Asic and dual-tube Asic.
It would be interesting to know the real value of air movement of each team in its maximum regime (to make sure) of every Asic model. I have a cheap anemometer and because I do not have a measurement area as big as the fans, I do not trust the values.
I have seen that there is a measuring instrument that would work well, it is a balometer.

Normally used to measure airflow ducts accurately.

Imaginary case:

From my experience in D3, which is a team of "single tube" and double fan I have determined that for a diameter of helix of 10, 5 cm, which is about 86 cm2, it is necessary a tube for the extraction with a section of 200 cm2 about 16cm in diameter (with two meters in length) so that the equipment is almost not affected. If for example I wanted to design a box that included two Z11 (double tube of a single fan per tube) I could only rule by trial and error in the choice of the section of the evacuation tube, come on that first I have no chance to know with something of accuracy the tube section that I will need.
However ... if we had a table with the references of air extraction real and quite accurate if we could know the amount of asics of a given model that an extraction tube would be able to admit. Imagine that I do the measurement with the balometer in the D3 and it tells me that evacuates about 300 m3 / h and that to stabilize the equipment (based on trial and error) I previously determined that I needed a tube of 16cm in diameter (200cm2) so that would associate that volume with that section. Well imagine that the Z11 to be double tube but a single fan per tube extracted about 430 m3 / h (measured with our balometer) ... what tube would use? Applying the "logic" above apply a "rule of three" ... if for 300 m3 / h was needed 200cm2 for 430 m3 / h will be missing X. X = 430x200 / 300 = 286cm2. And as we intend to put two Z11 would be about 286x2 = 572cm2 what standardized soundproof tubes are for that section? ... of diameter of 25cm (490cm2) and the next 31,5cm in diameter (774cm2). In that case I would opt for the 25cm because it happens that increasing the diameter of a tube greatly reduces the contact surface of this with air and it is very likely that this is a sufficient section. But well this is a calculation of "fat brush".

With all this I think it would be very useful to have a list of "real" flows evacuated from the different Asics that are in the market. It is more ... it would not cost anything that was a data more than into the specifications given by the manufacturer on each model.

I know it is a difficult task for us ... a second hand balometer is worth 1100 euros ... but if someone who had one and was in this "world" would be ideal to be providing data.

A greeting.

Any idea or correction that comes to mind is welcome.

(I hope somebody thinks it's a good idea Shocked)

I'm a carpenter. Building a wooden structure is faster and easier than all that. It is manufactured in this way for a possible commercial version that is sold disassembled. It is very important what you say about the possibility of fire. I have looked at boards of fireproof material and they are terribly expensive. I will choose to give you some fireproof paint, it will be the easiest and cheapest. The closet does not sound much ... it is to join the flows and be able to evacuate easily through a window. Here in Spain is usually a problem heat evacuation, especially in domestic use of Asics.

Well, I'm the man with the suggestions.

There is a situation that I can not avoid, I give you a REAL example so that you understand it and see if the suggestion is interesting or not.

There are coins that have little hash, are in their final phase or are coins that are only profitable up to a certain hash. The real example would be Xfox or AZART. I have them added and I have even measured the profit, but what happens to me is that when it enters into auto profit and the currency is the first one in profits, all my rigs enter at the same time. But when they all enter, the profit goes down so much that it stops being profitable, and that soon causes a change. Then again AZART becomes profitable again, and everything goes into the auto profit mode, and again the profir falls because it is too much hash.

The suggestion would be, when defining the pool of the currency, that there would be a field that tells AM how many maximum rigs can be in that currency. For example AZART I would put 2, therefore only 2 rigs would enter to mine that currency, the rest would not enter. If I left it blank, it would behave as usual.

When we play with shitcoins this happens many times, I enter and cause the fall of profit, because everything comes in. Being able to specify the maximum number of RIGS (any of which I have), that would give me more control when mining these small coins and not cause the profit myself and also cause excessive changes.

It can be done by creating different groups pools assigned to each rig, but that would make the management of AM more difficult and more difficult. I hope you like the suggestion that comes in handy to mine these coins that are in their final phase or that give few rewards and when a hash is exceeded, they stop being profitable. Is that right now the only thing I do is disable them, but I would like to control it with an option like the one I have indicated.

I do not know if the rules could do the same, I looked and I think not.

I hope you understand and I hope you consider it.

It is not necessary to put a fan of extraction, I did a test with a smaller cabinet of 4 asics and increased the dimensions of output until the heat stopped affecting the equipment. Then increase the dimensions proportionally until you reach 12.
I have avoided installing additional fans because a failure in them can cause the asic to break down. (google English translator) Wink

Hi guys.

I made this closet to evacuate the heat of the Asics through the window of your house (especially in summer).  It is designed so that you can put asic single tube, double tube and even rack. It can also work in reverse, taking the fresh air (in winter) from the street and expelling the heat to the room. (sorry but it does not soundproof).
