Baffle design


 

¿ªÔÆÌåÓý

I've uploaded pictures of a baffle we recently took off a system (http://groups.yahoo.com/group/VacuumX/photos/album/1665179354/pic/list). There's a disk with an elliptical cross section (think flying saucer) suspended in the middle of the fitting by four tubes (two on the bottom, two on the top). The baffle is water cooled and I suspect the water flows both through a water jacket on the outside as well as through the disk in the middle. No idea of the structure inside of the baffle portion but it has a pretty thin wall. So there's a bit more to these than the name would imply.
