A heat exchanger is a system that is used to transfer heat between two or more liquids. It is used in both cooling as well as heating method. It is simple and easy to use.
The liquids may be divided by a solid wall to prohibit joining or they come in contact directly. They are generally used in space heating, refrigeration, air conditioning, power station, chemical plant, petroleum refineries, natural gas processing as well as sewage treatment.
There is a simple example of a heat exchanger is establish in an internal explosion engine in which a flowing liquid is known as engine coolant flows.
It can be discharged through the radiator coils as well as the air flows through the past of coils in which it cools the coolant as well as incoming heat air.
There are three primary categorizations of the heat exchanger to flow pattern.
- In parallel-flow heat exchangers in which two liquids enter the exchanger at the same end as well as move-in parallel direction to one another to the other side.
- In counter-flow heat exchangers, liquids enter through the opposite side of the exchanger. It can be designed in such ways that it can move the most heat from the transfer medium per unit mass.
Due to reality, the average temperature difference along any unit length is higher. In this exchange the liquid move approximately perpendicular to one another through the exchanger. You can get more information about Equipment Service providers.
The capability of the heat exchanger is designed in such a way as to inflate the surface area of the wall between the two liquids during decrease opposition to liquid outflow over the exchanger.
The exchanger can also be affected by the addition of an arm or groove in one or both directions in which it increases the surface area as well as it may usually consist of liquid flood or encourage disorder.
The energetic temperature opposes the heat transfer surface changes with position. In the easiest arrangement, this is the “log mean temperature difference” (LMTD).
There are generally four types of heat exchanger which are following:
- Shell and tube heat exchangers
- Double pipe heat exchangers
- Plate heat exchangers
- Condensers, evaporators, and boilers
If we go through them based on the design featured that pointed out. There are certain distinct alternatives of heat exchangers available in the market. Some of the more similar alternatives employed throughout the industry contain the above-mentioned point.
