1. This design would have to be 3D printed because there is not a good way to manufacture it using traditional methods, so it would probably be paired with a 3D printed heat exchanger. 3D printed heat exchangers do not typically have tubes. Rather, they employ more complex geometry such as gyroids. edit: actually I'm not sure this is true. I guess you could come up with a similar design that could be IM'd. 2. Just because you could use the design in "other transportation industries" doesn't mean anyone is actually planning to do it. With the technology as expensive as it is right now, it would not make economic sense. 3. Having a spreader is not primarily about "easing the fluid flow," it's about ensuring that the entire heat exchanger gets fluid flowing through it. Typically this is worth it in applications where weight matters (because you can't afford the dead weight of part of the heat exchanger which is not actually getting much fluid flowing through it), but it is not worth it in industrial or HVAC applications (because it's cheaper to just build a bit larger of a heat exchanger). I do like the idea of a "floating spreader" - I will have to see if that has been done before.
