Emphasizing the performance of the Visi Cooler, in addition to good heat dissipation, the pressure loss must also be considered, but the suppression of pressure loss and the improvement of cooling efficiency, the opposite is technically the same, such as a medium size cold If the design is completely based on heat dissipation, the inside of the Tube needs to be made thinner and increase the number of fins, which will increase the air resistance; but if you maintain the pressure level, you have to bold the Tube and reduce the fins. The heat exchange performance of the film is relatively poor, so the modification of the intercooler is not as simple as we imagined. Therefore, most of the methods of cooling efficiency and maintaining pressure will start from both the Tube and the fin.
