"/It doesn't matter whether you liquid-cool or air-cool (or even solid-state-cool) something -- all that matters is the end-temperature you reach. In each case, you are ultimately dumping the excess heat into the surrounding air, anyway./"
Sure the heat is going into the surrounding air, but a liquid-air heat exchanger permits much higher heat transfer than a finned heat sink, so it depends on the rate of heat removal required to maintain a desired temperature difference from ambient. That of course is why ice's have radiators rather than fans blowing directly on the ice. If you are using LiFePO4 cells in 115 F (46 C) ambient you can't afford a very large temperature difference between the cells and ambient due to decreased cell life at higher temperatures. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Air-cooled-vs-liquid-cooled-batteries-and-charging-standards-tp4663777p4663827.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
