Hello.
I'm wondering if anyone could advise me on a cheaper alternative to silica aerogel for insulating my new computer.
I'm building a new computer and I'ver just begun work on the case. the case is actually a "case within a case" there is a tank within the case whcih will contain the motherboard/video cards/pci cards and all the other solid state devices, with external headers for connections.
Through this tank I am planning on flowing a liquid coolant. (obviously non-conductive). The coolant will flow in and out of the tank to a the resevour dewar and a heat-echanger, whcih I built out of a two-stage cryofridge (hooping to keep it stable at -90 C).
Here is the problem, however. To keep the temperature low and prevent unwanted condensation requires insulation. I've already ordered silica aerogel for the actual tank, but it cost me an arm and a leg just or enough to do the most critical parts of the system.
I'm in need of some other high effeciency insulation that won't take up a lot of space. I've looked into vacuum panel insualtion, but unforationaly they don't come in very good sizes or shapes for my needs and obviously they cannot be cut.
As it stands now, I may be going with alternating layers of mylar, polyester/foam compisit, fabric and a fiberglass material...
Any ideas????
(oh yeah...yes I'm serious. I am insane)
