Hello everyone....
I am currently working on a chiller which will work with a phase change cascade system. The final temperature should be somewhere around -80°C.
Obviously some problems come up at this low temperature. So here is a list with the items that I have taken care of so far:
1.) Heat Transfer Fluids from different manufactures. All are potentially good to about -130°C
2.) Modified pump that will allow temperatures as low as -100°C - you can also look it up at: www.gripumps.com / Model is the 18650/1 rated at 600 gallons per hour
3.) Hoses will be stainless steel
4.) Cascade system is in the works and will be available soon :D
So for right now I am planing on using some dry-ice to cool the liquid. It will use a simple copper pipe through a container with dry-ice for cooling. (Just on a note ... I am planing on cooling it for 2 weeks straight ... small heatload, approx. 50W ... including sublimation I will require approx. 700 pounds of the stuff :D ... )
The only thing that I am still missing would be a working Chiller Block. I would this kinda like to be based on the same principles as the Prometeia block.
1.) Heatexchanger Block for the fluid
2.) Connectors for stainless steel hoses
3.) Insulation
4.) "Case" with proper mounting
So right now I am looking for someone who would be able to construct this type of Heatexchanger or Chiller Block.
I would very much like to do this myself, but I lack equipment, skills and experience when it comes to that stuff...
Any and all help is greatly appreciated.
