Seems like they designed it as a radiator. Unlike A/Cs, refrigerators don't use fans to dissipate heat, but convection, because don't produce too much heat.

> Teams in Saarbrücken, Germany, have spent around 15 years researching and developing a technology using thin sheets of nickel-titanium to achieve optimal cooling or heating effects in circulatory systems. This includes creating a cooling and heating demonstrator and a continuously operating refrigerator.
