Vacuum Cooling
-
Heat can be transfered by induction. Use thermocouplers to create electric current, transfer the current via induction, the energy is then removed from the system via induction. Next?

Actually, thinking on it, you might induce someone to turn the fire on, so I suppose that counts.

I've seen computers cooled with fans (airflow), tubes (water cooling), and fully submerged in oil (oil cooling), but I've never heard of a computer kept in a perfect vacuum (well, aside from those vacuum tube things that only the wisest of CPians remember). For all you pysicists, would keeping a computer in a vacuum at room temperature help cool it at all? Or would it perhaps cause it to overheat? Neither? For your reference, here is an "artist's" rendition of such a vacuum sealed computer:

It would cause it to heat up. A lot. In fact it wold probably BSOD with that very rare BSOD error to do with overheating that I can never remember. Either that or catch fire. Especially if its a laptop.

Oxymoron? I kid, that does make sense... I wasn't quite sure how heat transfers in a vacuum. Would the same thing happen in space, where I hear the temperature is quite cold (near absolute zero)? It would be awfully ironic to boil in an absolute zero environment.

Double glazing. Think about it.

That's conduction. Convection needs a fluid.

Dont misquote him to make yourself look clever. He wrote: "cooling happens by convection (transfer of heat from one material to another)." Which is true.

I'm afraid it's not true, but it's an excusable mistake, of the kind that I myself would be happy to receive a correction on (so that I'll know better in future). Convection is the transfer of heat through a fluid. That is quite different from "transfer of heat from one material to another", which is called conduction. The differences are obvious, so the reason for the distinction in terms is equally obvious. It might be an idea to study Physics a little before making such comments, because that's not an excusable mistake. That you don't know even the very basics about heat and heat transference explains a lot about your opinions on GW.

Of course its true. Are you telling me that convection doesnt transfer heat from one material to another? I called you out for being a prig. Dont make it worse.

Yes. Read a Physics book. Google it. Check on Wikipedia. No resource that knows anything about Physics will tell you that convection is about transferring heat from one material to another. It is about the movement of heat through fluids. If a fluid comes into contact with another material, it can transfer heat to that other material through conduction. This is uber-basic Physics, at a low enough level that even someone who's all mouth and trousers should be able to pick it up. If that's too high a level for you, then I give in.

You are correct. But, not being a physicist it's all the same to me, so please excuse my misnomer, if you please. In any case, I think the basic idea got across. (Except to certain fat-heads, of course.)

Well, he his correct. Convection heaters transfer heat through the air (a gas, which is a subset of fluids). See here: Convection is the movement of molecules within fluids (i.e. liquids, gases and rheids). It cannot take place in solids, since neither bulk current flows or significant diffusion can take place in solids.[^]

To quote the prig: ""fat_boy wrote: Are you telling me that convection doesnt transfer heat from one material to another?" Yes." You should address your startling findings to him, not me.

I'm addressing them to you since you are incorrect, and he is correct. Convection transfers heat within a fluid. Conduction transfers heat from one material (be it fluid or solid) to another material.

http://obamacaretruth.org/No shit. You really dont get it do you. Just go back up the thread and look for where Mark intnetionall takes test out of context in a desire to criticise and appear superior to someone. In fact, why not also just search this forum for more evidence. Then, if you really want a laugh, go look at his website. It really is quite ammusing. For the 'wrong' reasons.

Indeed, the BSOD usually functions correct for me... screws me over completely at a very inopportune moment. It erroring and, say, helping me would be a rare event indeed.

I must say that I don't believe I have ever seen such a spurious and ridiculous claim of something being taken out of context. "(transfer of heat from one material to another)" was given as a definition of "convection". The overarching context makes no difference whatsoever to that, so was not needed in the quoted text. Should I quote the entire web page? All of CP? Copy and paste the Internet into my reply? So not only don't you know anything about Physics, but you appear to have difficulty with basic reading, writing, and reporting. Have you considered taking up boxing? Your thick skull might come in handy for that. Just so you know: Convection heaters warm a room by causing warm air currents -- i.e. they are designed to use only convection (transfer of heat through a fluid), rather than the radiation/convection combination of other room heaters. That's why they're called convection heaters. Again, had you even Googled or visited WiKipedia before opening the fat_mouth, you would have discovered this, and avoided the embarrassment of your comments about convection heaters. The only conduction heaters are things like soldering irons. And the only belittlement going on in this thread is: - You, jumping up and down like a naughty boy and impotently calling people names. - Me, basically telling you to shut up. No-one has belittled Ahmed -- except perhaps you, by deciding that he can't tell people to bugger off for himself if he doesn't want the information offered. Telling a non-native-English speaker he's used the wrong word is not belittling in any way. I speak two and two-thirds languages, and know that being corrected by native speakers is one of the best ways to learn new words and usages.
