Lifegrow Posted May 17, 2018 Share Posted May 17, 2018 A short video showing some simple passive liquid cooling using wheezeworts/AETN and radiant pipes. Dead easy stuff for when you need a little bit of geyser water cooling right down. A little follow on from yesterdays video : Link to comment https://forums.kleientertainment.com/forums/topic/90914-easy-passive-cooling-using-radiant-pipes/ Share on other sites More sharing options...

clickrush Posted May 18, 2018 Share Posted May 18, 2018 Nice video, it really shows the power of radiant pipes. What I was wondering is why do you find the tempshift plate layers there so useful? Wouldn't this speed up heat exchange if you completely left them out and just have metal tiles => doors => metal tiles?

The plates boost the transfer more than enough to account for the extra exchange from tile -> plate -> door. Tile -> door is limited by the wolframite's conductivity. Plates get around this limitation and supercharge each exchange. Tile/tile and tile/plate heat exchange behaviors are fundamentally different. In some (many?) cases, tile -> door is sufficient. But a default build should include plates at each transition as it's the best.

But a default build should include plates at each transition as it's the best. I believe you, but this makes very little sense to me. Didn't they change the way heat gets transfered to be an average between two material conductivities? And even if they didn't, wouldn't the doors be the bottleneck regardless? What is the underlying mechanism here?

wachunga Posted May 18, 2018 Share Posted May 18, 2018 They said they did, but the in game behavior shows that it's not happening. Use debug to place in vacuum a 25K tile of wolframite touching a 525K tile of wolframite, separate from them place a 25K tile of wolframite touching a 525K tile of tungsten. They exchange at exactly the same rate. If there was averaging, the rate would be different. Perhaps there's some strange behavior which makes the averaging happen sometimes and not others, but every test I have done shows that it never happens. To be fair I haven't tested every single combination possible. Tile/tile exchanges appear to still be limited to the lower conductivity. Tile/building (which a plate is) have always multiplied the conductivities together as long as I have been playing. The mechanism is that diamond's conductivity (80) is sufficiently high to boost wolframite's (15) and overcome the extra exchange of going through the plate. Alternately you can assume the plates will be very nearly the same temperature as the hot or cold side since those exchanges are "always on" while the plate/door exchange is only sometimes "on". Taking this view, you then have a plate->door->plate exchange which is much, much better than a tile->door->tile exchange. Here's a test to show that it's a multiplicative relationship. Place an insulated wolframite pipe (.46875 conductivity) in a 50kg tile of 500K hydrogen (.168) and an insulated tungsten pipe (1.875) in another 50kg 500K hydrogen tile. Rapidly unpause/pause until you get a single tick of temperature change. The wolframite increased by 18.2 and the tungsten 72.9. Tungsten's conductivity is 4x wolframite's and heated up 4x as much. You would expect 3.2x from a simple averaging of the pipe's and tile's conductivities (.318375 vs 1.0215). After a single tick things rapidly change because the delta Ts rapidly change, you have to measure that first initial tick.
