I'm no refrigeration engineer. I'm actually an electrical engineer by training. But the way my (now-broken) refrigerator works makes no sense to me. The cooling coils for both the refrigerator and the freezer are located behind the back wall of the freezer. The cold air comes into the freezer and then is circulated throughout the refrigerator using a simple fan. That makes a lot of sense.
The part that doesn't make sense is that the coils get so cold, they freeze up. There's a heater located inside the freezer to heat up the coils to prevent freezing. I've read that, in some cases, the heating element gets so hot, you can actually see it glowing. In my case, there was no glow, as the heater simply stopped working, thereby not allowing the coils to "unfreeze."
I haven't invested the time to come up with a better system, but there must be a better way to architect a refrigerator without using a heater. That just seems completely counterintuitive to me.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
