The heat exchanger is a system that converts heat from one fluid or gas to another without allowing them to combine or come into close contact. Heat exchangers are typically used in liquid cooling systems to remove heat from a fluid after it has passed through a cold plate connected to a heat-producing device. It is one of the most significant and widely used pieces of process equipment found in industrial sites.
Exchangers may be used for either heating or cooling, but in the industrial sector, mainly within plants and refineries, they are often used for cooling. Through heat exchanger suppliers, let’s take a closer look at what they are, how they function and, why they’re needed.
What are heat exchangers?
The heat exchange could be for the primary purpose of heating elements or cooling them down. Cooling is the most common feature of the industrial sector for preventing overheating machinery or volatile substances. There are several different types of heat exchangers, each with its own set of benefits and drawbacks that are tailored to specific application industries. The heat exchanger’s fundamental theory is that it converts heat without moving the fluid that holds the heat.
How Do Heat Exchangers Work?
Different kinds of heat exchangers use different flow arrangements, facilities, and design characteristics to operate in different ways. All heat exchangers have one thing in common that they all act to directly or indirectly expose a warmer medium to a cooler medium, thus swapping heat. This is usually achieved by using a series of tubes housed inside a casing. Heat exchanger fans, condensers, belts, coolants, extra tubes, and lines, and other parts and equipment all work together to boost flow or optimize heating and cooling efficiency.
What are exchangers used for?
Without even realizing it, we use Heat Exchangers in our houses, offices, and transit equipment daily. Heat exchangers can be used in a variety of settings, typically used to heat or cool houses or to make engines and machinery run more efficiently. They’re found in air conditioning and cooling systems, as well as heating systems. Heat exchangers are required in industrial plants and factories to maintain a stable operating temperature for equipment, chemicals, water, steam, and other substances.
- Refrigerators and air-conditioners: They collect heat from a compartment or room where it’s not needed and pipe it away in a fluid to a location where it can be emptied out of the way. As the cooling fluid is fully enclosed within a network of pipes, it never really comes into direct contact with the air it takes and transfers heat energy from the inside air and spills it in the air outside, but it never specifically interacts with the air.
- Power plants or engines: Exhaust gases frequently produce heat that is being wasted by escaping into the open air. The way to solve this issue is with heat exchangers located within the exhaust tailpipes or smokestacks. When hot exhaust gases rise, they come up against copper fins with water running through them. The heat is taken away by the water and returned to the plant.
- A car radiator: Another form of a heat exchanger is a car radiator. The radiator, which has multiple parallel aluminum fins exposed to the air, cools the engine with water. As the vehicle travels along, cold air flowing past the radiator dissipates some of the heat, cooling the water and heating the air, and enabling the engine to run more efficiently. The excess heat from the radiator is used to keep the car’s interior warm.
To wrap up
It is important to remember heat exchanger cleaning and servicing. We are leading heat exchanger manufacturers in India. Maintenance and servicing can differ depending on the form of heat exchangers in question and their design and construction. Heat exchangers must be well-maintained to function efficiently. By providing us with the specifications of your operation, our customer engineers will determine the right size and form of heat exchanger that is appropriate for your needs. Our heat exchangers are available as independent units or can be incorporated into a system.
