If you want to know the basics of a heat exchanger, then you can read this article without any hesitation. This article will throw light about the heat exchanger. You can also visit the website of Allied Heat Transfer to know about air cooled heat exchanger. To tell in simple words, heat exchanger is a device that transfers the heat from one medium to another. For example, a hydraulic oil cooler will dispel the heat from the oil by utilizing the air or cold water. Another example is the swimming pool heat exchanger that utilizes hot water to heat the pool.

The heat exchangers are available in different types and some of them are shell & tube, plate type and air cooled. Shell and tube exchangers contain many numbers of small tube, which is completely enclosed by a cylindrical shell.
Plate type heat exchangers work very much similar way like the shell and tube, but it uses series of plates rather than the tube. This type of heat exchangers comes in compact construction, which makes it easy it an ideal choice for use in food processing or with refrigerants.
Air cooled heat exchangers make use of air for transferring the heat from one medium to another. These types of heat exchangers are used in mobile and vehicle applications, where there is no source for water. Here, the cool air is provided by the movement of the automobile or by attached fan.
The efficiency of the heat exchanger is decided by different factors. The temperature differential is the difference between the coolant and hot fluid of the heat exchanger. For efficient heat transfer, the temperature of the coolant should be always lesser than the hot fluid. With lower coolant temperature, there will be more heat transfer. It is possible to cool the room ambient temperature much better by keeping a pack of ice than the just cool water. This same principle is being used in the heat exchanger.
The flow rate is nothing but the rate of the fluid that flows in the secondary and primary side. The rate of heat transfer will be more with the increased rate of fluid. Finally, the most import is that the heat exchangers should be installed as per the guidelines given by the manufacturer.
To ensure that the heat exchangers last for many years, one should install the right type in right way. Heat exchangers are made of robust material and they do not have any moving parts. Henceforth, there is no reason for these devices to go wrong sooner. When ordering the heat exchangers, make sure to send the right data design, so that the engineers would be able to create a ideal heat exchanger. For example, the high flow rate of fluid could result in erosion and high-pressure rate could result in leaks.
A heat exchanger could fail due to many reasons, which all could be easily prevented by taking appropriate measure. You can get more details and tips on heat exchangers by browsing the Internet.
