【Serrated Finned Tube】The serrations are small grooves or notches that are cut into the fin surface, which disrupt the boundary layer and increase the turbulence of the fluid flowing over the fins. This increased turbulence enhances the convective heat transfer between the tube and the fluid, resulting in a more efficient heat exchanger. #SerratedFinTube #EmbeddedFinTube #finnedpipe #finnedtube #finpipe
