[QUOTE="Design_Tom_, post: 1386853, member: 353494"] So the idea behind the design is not to chill the insulin pens but to keep them within room temperature/below 25C. The only reason why I say this is because obviously that takes much less energy than chilling to like 4C. Technology wise I think it is possible through the use of vacuum insulation panels that have extremely low thermal conductivity and a peltier module. I've calculated my heat loads to be about 1W at 40C (although in practice it may be more than this, hopefully can do some testing soon to get a better idea) and talking to my electronics tutor he think that a heat sink should be able to dissipate this without the need for a fan. Ideally this product could be used to keep insulin within room temperature on the go and then be able to keep it chilled if it was plugged into mains. however, without a fan I think my heat load when chilling would be too great - so some more design work needs to be done if this is a desired feature for the product. (Off the top of my head it could plug into a charging station with a fan built in rather than have it in the actual product). [/QUOTE]
