Vortex Cooler Mk IV

This is my design of a new part cooling nozzle for my Monoprice Maker Select v2. This is the Mk IV, Mk I, II, and III where the prototypes and were very ugly to say the least. A lot of learning came from those to make the Mk IV a reality.

The Mk IV is designed based on the inversion of an airplane wing to create a low-pressure zone on the inside of the circle, near the nozzle. This will draw in cooler air from above the nozzle and combine it with the air coming out of the cooler from the parts fan.

I say inverted airplane wing because in the ring I create a small venture effect to increase the air pressure, then direct the air out at an extreme angle to accelerate it. As the air accelerates, it starts to drop in pressure, which then requires more air to come in and fill the void. At the bottom of the ring, on the inside close to the nozzle, this new combined airflow is directed to a point about 2mm below the surface of the cooler. This should place the main bulk of the ai
