Good afternoon, dear visitors of the site.
I want to bring to your attention a small thing whose task is to cool the boiling water to the required temperature in home conditions.
As you know, this can be done by placing a container of hot water in another filled with cold, stirring hot water to speed it up. Or constantly pouring from a hot glass into an empty cold one.
At home, the author simply adds cold water to boiling water - this allows the quality of water, but in the city of parents - it can easily spoil the taste of tea / coffee, giving the drink an unforgettable flavor of bleach.
So let's get started and try to automate the process. The only condition for successful work fixtures It is a source of cold water with a continuous supply - in our case, it is a kitchen water tap.
So what do we need?
- copper tube (as an option: aluminum, steel)
droppers - 2 pcs.
a piece of wire
- a small piece of electrical tape
Correction of suitable diameter
-lighter
nippers or knife
awl or nail
So we take a piece of a suitable tube.
Copper works more efficiently, but aluminum or steel is also suitable. If you have at your fingertips a new unnecessary tube of the brake system of the car - it is perfect for our purposes.
How to choose a mandrel - in our case, it is ideal for cooling boiling water in a glass, cup or glass jar.
Please note, if you take a larger mandrel, the diameter of the turns will be larger, the cooling will be better, for example, for a pan, but such a device will not fit into a jar))) and may not fit in a cup.
Obgina tube district mandrel
We cut the tube to the length we need
The author accidentally had a suitable holder, but it can be made of pure copper or aluminum wire without forgetting to make a small hook for attaching to the cup, so this is not critical
Then we take the packaging of droppers and open the first one, actually from the kit we only need a long hose and a holding crimp tube to ensure a tight connection.
We attach one end of the dropper to our tube, for the connection, the circumstance that the dropper kit has everything is necessary.
We cut off the excess from the dropper tube. come in handy sometime another time
We take the second dropper, and also connect it to our copper tube, its second hole, we fix it as in the first case.
We begin to modernize the dropper - cut off with a knife or bite off the top of the valve with nippers. pierce with an awl its mesh valve
We heat the cut off part of the valve with a lighter and expand it, you can use your finger, the temperature of the heated plastic is low. But for the best effect, you can do this with the spout of a water tap right in the kitchen
We take this step in order to put the valve on the water tap
Next to the valve, just below it, with the help of electrical tape or wire, we fix the end of the tube of our first dropper - this will be our return
Total - we got a finished device
Getting to the test:
We put the valve on the kitchen faucet and open the water -
ATTENTION - slightly open !!! In order for cold water to flow through our system, because the diameter of the dropper tubes is small and the water flow in it is limited, opening the water tap too much will lead to a sharp increase in pressure and will easily disrupt our valve. Perhaps it would be appropriate to make some kind of adapter from an elastic material, for example silicone - or some other fixative. But no lock will save you from the large amount of cold water supplied to the cooling system.
Everything - the process has begun. Cold water passes through the tube of one dropper, passes through the tube, while taking the heat of hot water and through the second dropper returns to the sink.
The photo shows how quickly cold tap water can cool boiling water in a glass to room temperature - just over two minutes.
One more note: on process physics and better application
Fix the device in the upper part of the chilled water, then the cooling efficiency will be maximum - the chilled water will go down, and the remaining hot water will go up - thereby the process will be accelerated.
All good and useful homemade
