Purpose of Inter-cooler and after cooler Heat exchangers

Target equipment Inter-cooler and after cooler Heat exchangers are utilized in several industries, especially in chemical plants and oil refineries, textile industries. The purpose of these heat exchangers is to transfer heat from machinery to the other, most often from a liquid to the other. The constant efficiency of the heat exchanger demands for regular inspection to assess the equipment integrity An inter cooler, also known as the charge air cooler is heat exchange device of the air to air or air to liquid kind that is used on supercharged and turbocharged internal combustion engines in order to maximize its volumetric efficiency by raising the charge density of intake air via almost isobaric.

Types of inter cooler/ after cooler

The inter-coolers, sometimes called as the after coolers, come in varied shape, design and size based on the special requirements and performance of the supercharger system . Some of the usual spatial designs are

  • TMIC (Top Mounted Inter Coolers)
  • HMIC (Hybrid Mounted Inter-coolers)
  • FMIC(Front Mounted Inter coolers).

Each of these kinds could be cooled with an air to liquid system, air to air system , or its combination.

Function of inter cooler/ after cooler

Our inter-cooler heat exchanger to successfully cool the air passing through the device, The inter-cooler needs to be cooled with the aid of some outside means.

Many of the inter-coolers undergo cooling like an engine radiator where the air flows above the inter-cooler fins outside, that in return cools the air present inside the inter-cooler. Thus it is known as air to air inter-coolers. Some of the inter-coolers that are water cooled rather than by air are known as air to water inter-coolers or after coolers.

Advantages of inter cooler/ after cooler

  • The advantage that target equipment’s after cooler heat exchanger is that the air passing through the device can be cooled better when compared to a traditional inter-cooler where ice and excessively cold water is utilized to cool the device.
  • Water is a good conductor of heat rather than air; with the capacity to conduct four times its heat. It is for this reason that the after coolers are comparatively more effective. The downside is that as time goes, the water gets heated to the air temperature passing through the device and so loses its capacity to cool the incoming air.
  • Some of the after coolers utilize a small radiator in order to cool the water running through the system, thus making the heat exchangers ideal for racing as well as street use.
  • After cooler heat exchangers that are ice packed work well for applications of drag racing as only around ten seconds of functioning is required before one shuts down and goes to the victory dais.
  • For street applications and mild racing, after coolers or air to air inter-coolers with radiators are feasible since the ability to cool the incoming air does not minimize with time.
