What is the minimum spacing of shovel-tooth radiator?

The fin spacing on the shovel-tooth radiator can theoretically reach 0.2mm or even higher. However, in actual production, Wenxuan hardware radiator generally has many parameters, such as 0.5mm, 1mm, 1.5mm, because the short distance will affect the ventilation and heat dissipation effect, and the thin fins will also affect the stability.
