Have you ever watched wisps of smoke drifting from smokestacks and wondered how much energy they’re uselessly pumping into the air? Maybe less than you might think! Saving energy is a huge and costly problem for factory bosses and it’s one reason they often install devices called heat exchangers to salvage as much heat as possible from waste gases. Heat exchangers have lots of other familiar uses too. Engines in cars, ships, and planes use heat exchangers to work more efficiently, and if you have a refrigerator or an air-conditioner in your home, those are using heat exchangers too. So what exactly are heat exchangers and how do they work? Let’s take a closer look! Heat exchanger manufacturer Baton Rouge Louisiana.
Heat exchangers are used in many engines and machines to improve their efficiency. Heat exchanger manufacturer Baton Rouge Louisiana.
What is a heat exchanger?
Suppose you have a gas central heating furnace (boiler) that heats hot-water radiators in various rooms in your home. It works by burning natural gas, making a line or grid of hot gas jets that fire upward over water flowing through a network of pipes. Heat exchanger manufacturer Baton Rouge Louisiana. As the water pumps through the pipes, it absorbs the heat energy and heats up. Heat exchanger manufacturer Baton Rouge Louisiana. This arrangement is what we mean by a heat exchanger: the gas jets cool down and the water heats up. Heat exchanger manufacturer Baton Rouge Louisiana.
A heat exchanger is a device that allows heat from a fluid (a liquid or a gas) to pass to a second fluid (another liquid or gas) without the two fluids having to mix together or come into direct contact. If that’s not completely clear, consider this. In theory, we could get the heat from the gas jets just by throwing cold water onto them, but then the flames would go out! The essential principle of a heat exchanger is that it transfers the heat without transferring the fluid that carries the heat. Heat exchanger manufacturer Baton Rouge Louisiana.

How a simple heat exchanger works? A hot fluid (shown in red) flows through a tube coiled inside a larger shell through which another, colder fluid (shown in blue) is running in the opposite direction. Heat is exchanged by the fluids: the hot fluid cools down and the cold fluid warms up, without them actually coming into contact and mixing. This is a simplified example of a shell and tube exchanger: generally, heat exchangers of this design have many thin tubes running through a large shell. Heat exchanger manufacturer Baton Rouge Louisiana.
What are heat exchangers used for?
Geothermal pool heat exchanger.
You can see heat exchangers in all kinds of places, usually working to heat or cool buildings or helping engines and machines to work more efficiently. Refrigerators and air-conditioners, for example, use heat exchangers in the opposite way from central heating systems: they remove heat from a compartment or room where it’s not wanted and pump it away in a fluid to some other place where it can be dumped out of the way. Heat exchanger manufacturer Baton Rouge Louisiana.
A heat pump extracts heat from a natural geothermal hot spring, used to heat buildings at Hot Springs Lodge and Pool in Glenwood Springs, Colorado. The exchanger is the algae-covered plate full of copper tubes in the center of the water. Heat exchanger manufacturer Baton Rouge Louisiana.
In power plants or engines, exhaust gases often contain heat that’s heading uselessly away into the open air. That’s a waste of energy and something a heat exchanger can certainly reduce (though not eliminate entirely—some heat is always going to be lost). The way to solve this problem is with heat exchangers positioned inside the exhaust tail pipes or smokestacks. As the hot exhaust gases drift upward, they brush past copper fins with water flowing through them. Heat exchanger manufacturer Baton Rouge Louisiana.The water carries the heat away, back into the plant. There, it might be recycled directly, maybe warming the cold gases that feed into the engine or furnace, saving the energy that would otherwise be needed to heat them up. Or it could be put to some other good use, for example, heating an office near the smokestack. Heat exchanger manufacturer Baton Rouge Louisiana.
Diagram showing how a shower heat exchanger/heat recovered works.
In buses, fluid used to cool down the diesel engine is often passed through a heat exchanger and the heat it reclaims is used to warm cold air from outside that is pumped up from the floor of the passenger compartment. That saves the need for having additional, wasteful electric heaters inside the bus. A car radiator is another kind of heat exchanger. Heat exchanger manufacturer Baton Rouge Louisiana. Water that cools the engine flows through the radiator, which has lots of parallel, aluminum fins open to the air. As the car drives along, cold air blowing past the radiator removes some of the heat, cooling the water and heating the air and keeping the engine working efficiently. The radiator’s waste heat is used to heat the passenger compartment, just like on a bus. Heat exchanger manufacturer Baton Rouge Louisiana.
If you have an energy-efficient shower, it might have a heat exchanger installed in the wastewater outlet. As the water drips past your body and down the plug, it runs through the copper coils of a heat exchanger. Heat exchanger manufacturer Baton Rouge Louisiana. Meanwhile, cold water that’s feeding into the shower to be heated pumps up past the same coils, not mixing with the dirty water but picking up some of its waste heat and warming slightly—so the shower doesn’t need to heat it so much. Heat exchanger manufacturer Baton Rouge Louisiana.
How a shower waste-water heat exchanger works? Hot outgoing waste-water warms incoming cold water, reducing the energy you need to get the water hot and making the whole thing more efficient. Heat exchanger manufacturer Baton Rouge Louisiana.
Types of heat exchangers
All heat exchangers do the same job—passing heat from one fluid to another—but they work in many different ways. The two most common kinds of heat exchanger are the shell-and-tube and plate/fin. In shell and tube heat exchangers, one fluid flows through a set of metal tubes while the second fluid passes through a sealed shell that surrounds them. That’s the design shown in our diagram up above. Heat exchanger manufacturer Baton Rouge Louisiana. The two fluids can flow in the same direction (known as parallel flow), in opposite directions (counter flow or counter-current), or at right angles (cross flow). Boilers in steam locomotives work this way. Plate/fin heat exchangers have lots of thin metal plates or fins with a large surface area (because that exchanges more heat more quickly); heat exchangers in gas furnaces (gas boilers) work this way. Heat exchanger manufacturer Baton Rouge Louisiana.
