Define-Intercooler. 2 marks best answer



An intercooler is a heat exchanger that functions to remove heat from the air generated by an air compressor. An efficient intercooler will restore the temperature of compressed air to near environmental level.

Intercoolers are fitted because of:

  • Reduced air temperature, volume and increased air density for next stage.
  • Increases volumetric efficiency and compressor efficiency.
  • Due to reduced temperature give better lubrication for cylinder and piston rings.
  • Drain are fitted from which water and excessive oil can be drained out, to prevent air bottle corrosion and starting air explosion and fouling of intercoolers and pipe.
  • Save the work done.
