Immersion Cooler

05/05/2013 1:31 AM

Is there a similar mechanism to immersion heater that would cool a liquid by just immersing the equipment (Of course a low volume affair)into the liquid to be cooled ?

A thermoelectric cooler could probably be adapted for this. Immersion cooling coils exist for larger sizes, but I don't know if they are small enough for your needs.

Build a copper tube of appropriate shape. Fill with water. Freeze. Immerse in liquid to be cooled.

I saw lyn's comment. I wonder why he did not suggest adding a few cubes of ice .

I expect more scientific suggestions from the learned members rather flippant ones that do not give justice to the forum.

I want to know whether there could be a system that does not use a compressor etc., but uses some property exactly opposite to elecrical resistance to do the cooling. You may correct me if I am too idealistic.

My "flippant" answer is the best you are going to get when you provide ABSLOUTELY no useful information with which to work.

You want to cool SOME unknown liquid SOME how, but give no details of quantity, rate of flow, temperature of unknown liquid before and after cooling, the list of unknowns is endless!!!!

My first response was going to be ice cubes. That would have been a good appropriate answer in light of the total absence of detail you give us.

Think what you like, I don't care!

Ice will work, we have used that to cool acid mixtures with the ice in plastic bags to avoid dilution.

I expect more scientific suggestions

Please provide more information then. A guess based on a very broad question is hardly scientific or that helpful to anyone.

My guess is liquid nitrogen (application specific naturally). Does this valid answer help with your particular application?

Can you provide more information?

An immersion heater is made with different outer sheaths, SS, copper coated with Chromium, etc., depending upon the liquid to be heated. For water, immersion heaters are usually employed. This is a convenient way, for Geysers, and even for sporadic applications such as heating a bucket of water for a bath etc. It is convenient, economical and fast depending upon the wattage employed.

Now, I wanted to know, whether the combined brains in the forum could suggest an appliance with say nano technology or whatever, that would be a similar one to the immersion heater. If more details are needed, I am afraId, I am helpless.

Don't you know how much of what liquid you want to cool how fast from and to what temperatures? Some techniques have already been suggested.

If that is what you are after then try an internet search for "carbon nanotube".

If more details are needed, I am afraId, I am helpless.

You really haven't given us much to go on except "anyone got any ideas on small immersion coolers?"

Buy split type A.C, bend the out put side copper tube like immersion heater coil and pass the copper tube through liquid before connecting to room unit, it will cool the liquid also your room too.

You're seeking a device "...that would be a similar one to the immersion heater."

Is this what you had in mind?

If so, you can do it using thermoelectric or peltier effect cooling elements. But first check these out:

http://simple.wikipedia.org/wiki/Second_law_of_thermodynamics

http://www.physics.utoronto.ca/~phy326/xrf/APPENDIX%20C.pdf

Remember, heat transfer is a one-way street!

...and we expect more involvement of a poster with their own question, a simple Google search on "immersion cooler" turns up over 1.6 million hits with plenty of good answers in the first few pages, one of which will probably solve the problem that you did not share with the forum.

The answer is No.

Heat can be "created" from another form of energy such as done with the resister in an immersion heater. But that is a one way street. The only way to remove heat is to let it flow into a colder substance or to supply energy to actively pump it out.

Google on Peltier/thermoelectric cooler. It's actually a solid state heat pump; two surfaces, one gets hot the opposite side gets cold, totally reversible by simply reversing the DC input polarity.Like any other heat pump its performance depends upon the surface temperatures, their delta T, and the rate of heat rejection. Unlike a mechanical heat pump their performance/eficiency is relatively poor, but they're small, there is no refrigerant to leak, or compressor to make noise.

research ' josephson junction'... available as 3/16 thick ceramic plates with active semiconductor between them. apply power, 1 side heats, the other side cools

To get enough temperature difference to drive heat movement via a small package might require cryogenic methods. E.g., lower a vial of liquid nitrogen into the liquid to be cooled.

We use peltier cooling for small volumes down to -40°C. For lower temperatures we will evaporate liquid nitrogen & pass through a heat exchanger. For higher temperatures we use water chillers, again, through a heat exchanger & add glycol if it is to go below 0°C.

OP, don't you get it? No useful information.

Immersion cooler: Those little plastic balls filled with some liquid that freezes when you put into the freezer.

Now, take the ball, put it in a glass of water and presto: An imersion cooler.

Problem solved. It satisfies both conditions. It's immersed and it cools.

I think we're done here?

Try Hart Scientific. They have a neat little one for freezing triple points.
