These are D Cup Coolers (also known as Bar and Fin Cooler), or Plate and Fin type coolers, typically because cooling fins are attached to the heat sink, thereby increasing its surface area to greater cooling effectiveness.Oil flow handling up to 1000 LPM, Cooling capacity up to 57000 Kcalh.Air cooled heat exchangers oil coolers are lower in cost and maintenance, and can come in very small sizes depending upon the requirement, and still be effective. Water, on the other hand, has a higher specific heat capacity, density and thermal conductivity, and hence has a greater cooling capacity. Furthermore, the water jacket around an engine is very effective in significantly dampening the mechanical noises.
