as far as i know radioters is used for heating up houses

but i found out that they also cool down airplane engines y is it then called radiator

Wellll...

A radiator in a house usually runs hot water through a series of pipes that have a very good level of heat transfer. So when the water gets there it looses much of its heat energy through the pipes that radiate it into the air (thus a radiator).

A radiator on a airplanes engine does essentially the same thing...radiating heat into the cold airstream going past the aircraft.

If you want to think of it in simple terms...an airplane radiator is simply trying to heat the whole world http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

It just is.

Guess what!!!!!

Cars have them too.

Because they <span class="ev_code_RED">RADIATE</span> heat either into your house or via the liquid cooling away from your engine

Exactly what I was gonna say but I didn't o well and now we know it simply cools the engine so you don't ge tthat grinding squeaky noise right before your engine poops out. http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif

I <span class="ev_code_RED">radiate</span> , myself. But I stay hot in the process.

Is there something wrong with me?

Try stopping radiating...and see how hot you get then http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

People radiate, but have internal heating. They make good space heaters, or can be enslaved by a Matrix to produce electricity.

OMG! That would make an awesome movie......

Imagine mankind enslaved to provide heat and or electricity for an inhuman alien race.

We can even make it so that the humans are fed a false reality to keep them compliant.

Then there's this guy who everyone thinks is the 'saviour' of mankind. He's all powerful. He's the one to get everyone 'home.'

We can call it 'The Wizard of Oz.'

Stephen Spielberg needs to hear about this idea. Fritz, your a genious.

Now how can I get ahold of Stephen?

Well, I think you've gotten your answer http://forums.ubi.com/images/smilies/16x16_smiley-happy.gif

The two of them use radiators (well, some aircraft have radiators, just like some cars and motorcycles have radiators while others don't) for similar but different reasons though

An air-cooled engine, such as (most) radials and rotaries (not a wankel engine, an engine that keeps it's crankshaft static and the crankcase revolves around it) don't use radiators. they are air-cooled, just like many motorcycles and the old VW Beetle

In a house, the system is designed to circulate and heat up a confined space. It's materials and methods are optomised for that application

In a car or motorcycle or airplane, a radiator is designed and built to circulate and allow the most efficient transfer of heat OUT of the system, to the airflow, and thus cooling the engine, but only to a certain degree.

Any engine is most efficient as a powerplant at a specific temperature. In an automobile, this is usually around 180-220 degrees F depending on the application and so forth. You want it "cool" but that's a relative term

All (to my knowledge, I am a vinatge car amateur restorer/owner/wrecker for the last 17 years) radiant cooling systems in modern construction systems (for example- from WWII to present day) use a system by which higher than atmospheric pressure is applied to the cooling system, thus raising the boiling temperature of the coolant. The coolant mixture can impart some small degree of protection against boiling at 212 degrees F at the sensor, but the real thing that raises the boil-over temp is the pressure cap on the system. Water is still the most efficient basic liquid for cooling. "Coolant" is often really "anti-freeze". For instance, a 15 psi cap gives you a 247* F boil-over temp. The system is designed and rated to whatever temp the engine design requires; putting a 18 psi cap onto a system that needs a 15 psi cap will not help you out, it will likely cause damage if your system isn't working correctly

In an aircraft powered by a liquid cooled piston engine, opening the 'door' or 'flaps' to the duct/housing that contains the radiator(s) will increase the airflow around the radiator(s) and increase the amount of heat transferred to the airflow, at the expense (typically) of drag
