nah, radiative cooling means that radiation is the only mechanism for heat exchange in use. I’m pretty sure most modern air coolers use forced convection as one of their heat exchange mechanisms.
How does heat get from the water radiator to the air?
Radiation.
Atoms don’t physically touch. The electrostatic force that both binds atoms into molecules and keeps molecules separated is mediated by photon exchange.
Counterpoint: at the boundary layers, right where the air touches the fins, the main mechanism for heat exchange is conduction. Ultimately, convection is just conduction, where the medium undergoing heat conduction is a moving fluid, which massively amplifies the rate of heat exchange.
Air is kinda shit at taking in heat through radiation, but fine at doing so via conduction and convection.
The metal atoms in the fins don’t move into the air. They stay on the fins. The fins’ atoms have to transfer their kinetic energy via photon exchange to the atoms in the air.
This really annoys me, especially on Reddit r/conservative and r/conspiracy subreddits are full of images. Not even images of articles, but just images of headlines. And you have massive discussions about it
Another popular thing is a screenshot of a tweet, most often posted by a complete nobody.
I enjoy the replies… You’ll have AOC, Elon, Trump etc make some statement… And then Rando McRando will have a reply back to them.
Like bruh(ette)… no way in the world do these celebrities with massive followers read your reply… it just falls into the void that is the 99+ for notifications
Teenagers will often poke holes in a pop can to turn it into a makeshift pipe for smoking marijuana. This artist made a glass pipe to imitate that look. It’s ironic because if you had a glass piece for smoking you would never use the inferior pop can method, and yet this is exactly the combination of those two different approaches.
I knew people do this, but I was always to afraid of inhaling something extremely toxic to do this myself. And I used to be a chain smoker, when this was relevant for me. Not sure, if I was cleverly stupid or not.
Yes, aluminum cans are lined with plastic to protect the flavor of the product and prevent corrosion. Melted plastic fumes are generally considered bad. #TeamApplePipeOrSometimesCarrotPipeInAPinch
