Introduction: Can Cooler Mod

Christmas gift from the love of my life to her favortie geek.
USB Beverage Chiller
The CoolIT USB Beverage Chiller is the only way to keep your drink cold while you're at your computer and it looks cool on any desktop!
Works great but I needed to mod it a little to bring it up to my specs. Bottom stayed cool but top of can warms up and we cant have that! :-)

Step 1: First a Mockup

I grabbed a old Nasa can cozy and cut about 1/3 off the bottom leaving two ears that I could wrap under the cooler to keep it up right and in position. A little duct tape never hurts any project :-)

After testing with a infrared hand temp scanner the top of the can was now within 3 degrees of the bottom. Not bad

Step 2: Crack It Open!

Now to see what makes this baby tick! Coolitssytems gets high marks from me. They used screws! Easy to crack the case. Yea!

Step 3: Piezoelectric Spot Cooler

One small fan, one big aluminum heat sink and a piezoelectric heat transfer plate and thats all. Nice and simple!


OK mock up works, but Duct tape on the desk is a little tacky, Now it time to jump into Inventor and start a 3D model


Modeled the can cooler and added some insulation.


I decided to add a plastic sleeve around the insulation to give it some more rigidity.


Using the data from my Inventor model I made a rapid prototype sleeve using a Genisys xs 3D printer. I made the ouside walls .125 thick with a honey comb pattern to trap air as a additional insulator.

Step 8: All Done

I created the sleeve to slip down on both sides of the cooler with two little ears. I used some double faced tape on to keep the whole thing in place centered on the cooling plate.

I slipped the cozy inside of the sleeve with a little spray stick on the inside walls.
Note I added a lip to the sleeve to keep the cozy from sliding out when the can or bottle is pulled out

Now I can have a cold can when ever I want and never have to come back to a warm soda!!

Isnt technology great!!
