Vacuum Chamber

[rlara]

Hi to everyone:

I am trying to make a test vacuum chamber and wanted to know how to go about it.
Inside vacuum will go down to 6.67e-3 Pascal = 9.67 e-7 psi = 5 e-5 torr.
This vacuum chamber is small, 3 x 8 x 3 inches, machined out of aluminum 6061-t6.
My concern right now is to determine wall thickness in order to support the vacuum
Inside. To determine this I was thinking that the load on the outside walls of the chamber
would be the atmospheric pressure 1 ATM or 14.969 psi, and inside would be considered
as zero pressure, so I applied a pressure of 14.969 psi to the walls. My question is if this
is correct or is there other factors I should take in to account.


Thanks

Vacuumsage:

You are right, the component is small so we are trying to match the chamber to the component. We just got this peltier thermo electric plate that we want to use to produce the thermal profile. The product specification requires a certain profile (i.e. ramp up and down at specified rates) due to this we need to have control over the thermal sequence.

Have you had any experiance using these types of thermo electric plates?

Thanks
