How Heat Exchanges Can Provide An Advantage

By on April 15, 2018

The world of heating and cooling is complex and as a result, technicians are getting paid more and more as the years go on. There are plenty of people that work hard to understand the world of engineering so that they can work within this field. As a result, there are plenty of advantages for businesses and people when trying to understand heating and cooling.

The three types of heat exchangers that are often utilized Parallel-flow or counterflow configuration, cross-flow configuration, and shell-and-tube configuration. In 2013, the revenue of boiler and heat exchanger manufacturing in the United States managed to reach just about 7 billion United States dollars.

The advantage of understanding heating and cooling often comes down to money. As previously mentioned, this is a strong industry and market and there is plenty of money involved. As a matter of fact, the projections surrounding the heat exchanger estimate that this market is going to reach nearly $19.14 billion by the year of 2021. So each year this rate will grow at least by 8.2%.

One advantage of using a heat exchanger deals directly with the lifespan. As a matter of fact, the outer shell portion of the heat exchanger can last nearly 40 years without any sort of corrosion or problem. As a matter of fact, it won’t even serious be damaged within this time, outside of any crazy circumstances.

When a heat exchanger’s fluids pass each other more than once, the heat exchanger is called a multi-pass heat exchanger. If the fluids pass each other only once, the heat exchanger is called a single-pass heat exchanger. Heat Exchangers are used to transferring heat between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact.

Using a heat exchanger on liquids and solids is the best way to go as it’s smooth functionality gives it a strong advantage over other methods. The very close proximity of process fluids within a diffusion bonded heat exchanger core creates an exceptionally high heat transfer rate with correspondingly high efficiencies and allows close temperature approaches of up to 2oC.

For the heat transfer to occur two fluids must be at different temperatures and they must come thermal contact. Heat exchange involves convection in each fluid and conduction through the separating wall. Heat can flow only from hotter to cooler fluids, as per the second law of thermodynamics.

In parallel flow heat exchangers, both the tube side fluid and the shell side fluid flow in the same direction. In this case, the two fluids enter the heat exchanger from the same end with a large temperature difference. In cross-flow heat exchangers, one fluid flows through tubes and second fluid passes around the tubes perpendicularly.

In Conclusion

There are technicians that spend years studying the world of heat exchangers that have a strong advantage when it comes to understanding information. If you are someone that needs any help with heat exchanges make sure you contact a professional!
