Heat exchanger and types of heat exchanger?

A heat exchanger is a gadget intended to proficiently exchange or
“trade” warm starting with one issue then onto the next (between a strong protest and a liquid, or between at least two liquids).

At the point when a liquid is utilized to exchange warm,
The liquid could be fluid, for example,
Water or oil, or could be moving air.
The liquids might be isolated by a strong divider to anticipate blending or
They might be in direct contact.

Their applications include:

  1. Space heating
  2. Refrigeration
  3. Air conditioning
  4. Power stations
  5. Chemical plants
  6. Petroleum refineries
  7. Natural-gas processing
  8. Sewage treatment

The exemplary case of a warmth exchanger is found in an IC
(Internal Combustion) Engine in which a coursing liquid is known,
As motor coolant moves through radiator curls and wind streams past the loops,
Which cools the coolant and warms the approaching air.

Another model is the warmth sink,
Which is an inactive warmth exchanger that exchanges the warmth created by,
An electronic or a mechanical gadget to a liquid medium,
Frequently air or a fluid coolant.

Heat is exchanged by conduction through the exchanger materials which separate the mediums being utilized.
A shell and cylinder warm exchanger disregards liquids through and tubes,
Though an air-cooled warm exchanger goes cool air through a center of blades to cool a fluid.

There are different kinds of heat exchangers-

  1. Shell and tube heat exchanger
  2. Plate heat exchangers
  3. Plate and shell heat exchanger
  4. Adiabatic wheel heat exchanger
  5. Plate fin heat exchanger
  6. Pillow plate heat exchanger
  7. Fluid heat exchangers
  8. Waste heat recovery units dynamic scraped surface heat exchanger
  9. Phase-change heat exchangers
  10. Direct contact heat exchangers
  11. Micro-channel heat exchangers

Warmth exchangers are regularly utilized for the cooling of hot gasses and fluids, particularly in mechanical and producing forms.

They can likewise be utilized to produce warm; for instance,
An Exhaust Gas Heat Exchanger can,
Utilize the warmth from fumes gasses to warm up a water circuit,
Which would then be able to be utilized around a building?
