CAD of Rev 3 End of first semester capstone overall assembly model.	POC 2.0 New idea to increase cooling power using water based coolant.	Early concept sketch Dry Ice with Vapor Cooling proof-of-concept (POC) test
Proof-of-concept (POC) 1.0 First proof of concept using dry ice and vapor cooling. Found cooling power to be too low with vapor alone.	Blower icing issue Proof of concept test showing icing of blower when used for moving vapor. Low pressure was causing atmospheric moisture to condense and freeze, reducing efficacy of the blower.	POC 2.0 Heat Exchange Underside for water cooled subject with dry ice cold reservoir.
POC 2.0 Connected dry ice plate to heat exchanger resulted in frozen coolant. Heat exchanger temperatures fell to around -100F.	Internals Assy with Detail New plan to solve coolant freezing.	Lifting tray detail New system to solve coolant freezing by controlling heat transmission to cold reservoir.
Milling pocket into tray New system to solve coolant freezing by controlling heat transmission to cold reservoir.	Dry ice lifting tray Angle shown is exaggerated, only about 3˚ is necessary.	POC 3.0 showing set-up CCW from bottom right: electronics including 5V and 12V system meters, thermocouple displays, microcontroller and pump relays. Power source, internals assembly on drip tray.
