Who would have thought that craft brewing and PC building had so much in common. A copper chilling coil is pretty useful. Love the videos - Keep up the good work Jay and Phil.

[@SupeIex]

The water flow on the outside of the copper coil is relatively important, since as the heat transfers out of the loop and into the bucket pool, what would happen is it would make 'hot pockets' around the copper heat pipe, in turn, over time the loop would warm up faster. Since you dropped dry ice just by itself into the bucket, that creates flow due to its energy loss and co2 emission. The only issue with that style is your dry ice usage is potentially inefficient and uncontrolled. When the dry ice was in an inner bucket, the surface area was limited, limited to only the walls the dry ice touches, and the air that slowly transfers energy to the dry ice; this allows the for the dry ice to continue to cool the loop, but not over cool, whilst dropping dry ice into a liquid causes the surface area be of the full dry ice block, and the dry ice will quickly be wasted, with the efficiency dropping, as the amount of energy that needs to come to the bucket exponentially increases, which makes other sources, like the room, your hands, etc, quickly transfer heat and waste the volume that could be used on the loop. Basically, there's a stopping point for when you're wasting more dry ice then actually converting into usability for the loop.

[@joefowble]

I think Jay's previous observation with the cooler and rad in ice water in cooler was more related to the radiator fins being too dense to allow convection flow through rad while the giant coil doesn't block external convection. But jay got bored and sent it so coils were freezing because dry ice too cold to not be metered.

"we win! what did we win?" -Jayztwocents 2020

[@SpeedRacerOne2]

The two loops are a good idea (disclaimer, my experience comes from brewing beer professionally). Using a cooling coil is a standard approach in small batch brewing or homebrewing but the problem (in this scenario in brewing) that people often make is that they are not moving both liquids (cooling liquid and hot beer). You end up cooling at a much slower rate as the temperature localizes around the coil and then is less efficient in transferring through the rest of the liquid in the vessel. By whirlpooling the liquid (running it from top to bottom causing it to spin in the vessel) like you were doing in the bucket, you significantly increase cooling efficiency. You can also think of this like defrosting a steak in water. If you keep the water running slowly so that there is movement around the steak then it will defrost quicker. Now don't get me wrong, the cooling will still occur - your coil will cool and the steak will defrost - whether you move the other liquid or not. The larger the temperature difference, the more you will see it work. I wanted to give my two cents (see what I did there) to backup the soundness of your initial design in this video around the dual loop. Side note, grain alcohol has a freezing point beyond -100c but viscosity does increase, especially below 0, so you will have a similar issue to the glycol. I'm not sure which is ultimately better but it would still be a problem you would face. Awesome video, Jay and Phil!

Oh jesus, that copper coil threw me back into making beer with my brother in our backyard. We had a copper coil probably twice that length for the 12 gal pot we used. Explanation for the beer making curious: After getting the wirt (basically pre-beer tea made from the grain) then gotta get the liquid to the correct temperature for the yeast as fast as possible, the quicker you can go from boil to perfect yeast temp the less chances of the brew getting tainted by the bateria and whatever in the air.

[@erik365365365]

I would wonder if this would do anything. Like is salt even solvable in the glycol?

[@simps002]

Glad you were able to get a better result on your scores Jay. (B.S. in mechanical engineering) Not sure if anyone else has brought this up, but the fin density of the block is not really designed for more viscous materials such as glycol. There is a flow characteristic called the laminar flow boundary layer that will limit thermal transfer because of a thin layer of material that basically sticks to the surfaces in your loop and that heats up without being replaced by new coolant (think a drop of water sticking to glass, it is all surface tension). You get over this in a similar way to the extra cooling you get by dipping the radiator or coil in and out of the bucket because you are disrupting that flow boundary replacing the "hot" fluid contacting the fins with cooler fluid allowing better heat transfer until that fluid warms. Fins in the block do the same thing, but the distance between the fins has to be designed to optimize the laminar flow disruption for the intended coolant (making the fluid more turbulent, thus increasing heat transfer). This new block was likely better, but what may be happening is that a little bit of your coolant may be going into the fins, but not actually be replaced because the fluid sticking between the fins is causing too much resistance to flow between them and just pushing the material around the outside of the fins instead. You did hit on a better alternative to the glycol though. High percentage Alcohol, such as rubbing alcohol at 90% is closer in viscosity to water than glycol and doesn't freeze until -89C. If you decided to go this route, you do need to be careful because you are dealing with a flammable material running through a pump that also can eat away at your O-rings that are already going to be stressed due to the cold temps. Beyond that, you are talking needing to do custom part designs such as der8auer has done to meet your needs for specific circumstances.

I'd recommend a mechanical agitator instead of the secondary loop to circulate the coolant in the bucket.

The helical shape will mix the out coolant slurry to prevent hot pockets from developing. Or maybe repurpose an ice cream churning bucket if you want to get real fancy.

I've always wondered how well filling a chest freezer with water & antifreeze would work. Sure you can't run it constantly and it will take ages to get down to -18c+ (but it also works both ways). Higher temps also mean a higher specific heat capacity as you can use a higher concentration of water, plus boosting the flowrate too! That could actually work better than such high concentrations glycol at a reduced flowrate at -35c, and a hell of a lot less hassle...🤔 PS: The reason I mentioned adding some alcohol to the mix was to make the liquid easier to pump around the system (glycol doesn't really freeze it just becomes a thicker and thicker gel).

[@thebarkingmouse]

The freezing point point pure ethanol alcohol is -114 C (-173.2 F). Dry ice sublimates at -78.5°C (-109.3°F). If I were doing this project I would make a heat exchanger. Have a pot full of pure ethanol (or as close as you can get it). Run a copper loop through the ethanol in the pot with as many loops as you can get. Fill the loop with ethanol ( the challenge will be getting pure ethanol. You could use high proof alcohol like everclear, but you may have to do a freeze distillation to get rid of the water. That would require experimentation.) and pump the ethanol through the loops in the pot full of ethanol (closed loop into the heat exhanger). Keep in mind also that the viscosity of ethanol at -50c is roughly 3 times that of water at STP. Your pumps will be working hard and may fail. You may have to choose a different type of pump. Also, the bubbling dry ice will produce a lot of ethanol vapor. You will need to exhaust those gasses or you may be making a potentially explosive air mixture. I'd use a pressure cooker to hold the heat exchanger, and drill & tap a large diameter hole (at least an inch), and attach that to a hose I'd run to the bottom of a 5 gallon drinking water jug. Exhaust the gases that bubble up through the water. The main concern is buildup of potentially explosive vapors, oxygen displacing gases, and intoxicants in the air you are breathing. But exhausting the gases bubbling up through the water will solve that. So fill the closed loop with ethanol. 3/4 fill the pot (heat exchanger). Immerse the copper loops in the ethanol in the pot. Drop in the dry ice Close & secure the lid (not a risk for explosion because the vapors are being forced out through the hose). Either directly duct that hose to open air outside, or bubble through water and then exhaust the gases with a fan. You should be able to drive the temps of the ethanol down to -70 or even cooler without freezing the ethanol.

[@MikrySoft]

@@thebarkingmouse Getting pure ethanol shouldn't be an issue, I have seen many US-based KZbinrs use good ol' Polish Spirytus Rektyfikowany, which is 96% (192 proof) ethanol. As luck would have it, ethanol/water mix has the lowest freezing temp at that concentration (under -115C if I read this commons.wikimedia.org/wiki/File:Phase_diagram_ethanol_water_s_l_en.svg chart correctly). On the other hand, table en.wikipedia.org/wiki/List_of_cooling_baths says that ethanol should perform as good as isopropanol, which should be much cheaper than human-grade alcohol and both are mostly safe to use with PVC tubing. Maybe not for 24/7 use, but neither is glycol.

Fluid circulating on the outside of the coil will improve cooling performance. It is like moving air over your radiator with fans vs letting the air sit stagnant. The fluid next to the coils will be warmer than the rest of the fluid, just like air next to a radiator will be warmer than the rest of the room. Probably not a huge deal here, but it would have a positive effect to keep it moving.

[@joshhayes3433]

As a home brewer, this is what we do after the boil and it becomes wort, we need to chill it down to about 70F as quickly as possible and one of the best ways to do it that is using a counter flow chiller, where the ice cold water is transferred the opposite direction as the very hot wort. We have an end though, and that end is when the whole of the wort has reach about 70F (give or take), then we’re done. I don’t know if this would help, but looking up a counter flow chiller or an immersion chiller (your proudly made hardware store loop :) ) might be a next step or something you could try.

[@kristiangronberg3150]

Actually, having less of a mix in the buket might make sense, even if the buket starts to freeze, the loop still has headroom, and because the phase change from liquid form to solid (ice). Takes lot more energy than changes is temperature gives you a lot of headroom cooling the bucket down with the dry ice. When you have the copper tube in there, you probably don't need an other loop or bucket, the buket probably just makes things worse. When the dry ice boils, it's probably mixes the water enough.

How about using a physical form of agitation for the water/coolant on the outside of the coil. Like a paint/drywall mixer you would use on a drill.

[@cdnarmymedic]

For gits and shiggles you could revisit the ice bucket again. This time use a saltwater and ice mix in the bucket. A saturated saltwater solution can get as cold as approx -21C (-6F), but since it won't get as cold as dry ice you can better control what temperature the bath sits at.

[@dr.peterscroll422]

Really enjoyed watching your experiments with cooling the CPU. Many have suggested using alcohol. Vodka is no use as it contains water. You can try pure ethanol as it is not poisonous. Its boiling point is 78.37C or 173F and its freezing point is -114.1C or -173.38F. Need to ensure that the alcohol does not reach its boiling point.

You said that your tubing was pinching because it was under a vacuum, what you need to do it pressurize the loop to lower the freezing point of the liquid going through it. It's the same reason your houses water pipes don't freeze until a ways below freezing. Pressure in lines makes it harder for water to freeze.
