What I'm going to do is build a Styrofoam box around one of our units on the vibe table. It'll be secured to the table during vibration. I'll have a tank of LN2, a hose, and a solenoid valve, probably all 1/4". A simple controller will control the solenoid based on temperature. When the LN2 is...
The purpose of this system is to mount on a vibration table for product testing. We have thermal chambers, but not ones that have simultaneous temperature-vibration capabilities. We want to know the effect of vibration when the product is at -40º C.
I've never worked with LN2. My first thought...
The goal is to design an LN2 Freezer system that is portable and inexpensive as possible. I want to use Styrofoam (polystyrene) walls with a certain R-value to be built around a unit with a certain heat gain. The idea is to purchase components such as a tank, hose, (pump?), solenoid, and nozzle...
