What are heat exchangers uses?

4 min read

A device may be a device designed to efficiently transfer or “exchange” heat from one interest to another. Once the fluid is employed to transfer heat, the fluid may be a liquid, like water or oil, or may well be moving air. The foremost standard style of a device may be an automotive radiator. In an exceedingly heater, an answer of water and ethanediol conjointly referred to as liquid transfers heat from the engine to the radiator then from the radiator to the close air flowing through it.

This method helps to stay a car’s engine from warming. Similarly, Lytron’s heat exchangers are designed to get rid of excess heat from aircraft engines, optics, x-ray tubes, lasers, power provides, military instrumentation, and plenty of different forms of instrumentation that need cooling on the far side what cool heat sinks will offer. The heat exchangers are manufactured by heat exchanger manufacturers. 

There are numerous forms of heat exchangers. Lytron’s heat exchangers offer air-to-liquid cooling, liquid-to-air cooling, liquid-to-liquid cooling, or air-to-air cooling. With liquid-to-air cooling, the warmth is transferred from the liquid to the air. This kind of cooling is mostly accustomed to cool method fluids. Liquid-to-liquid cooling is additionally accustomed to cool method fluids. However, the warmth is removed by another liquid rather than by air. 

Lytron has been producing one in every of the foremost comprehensive used device technologies, tubes, and fin heat exchangers, for twenty years. Tube and fin heat exchangers offer air-to-liquid cooling or liquid-to-air cooling. They include fin, pin tubes, come bends to attach the hairpins, a tube sheet to support and properly align the tubes, a header with inlets and shops, aspect plates for structural support, and frequently a follower plate.

The tubes offer the trail for the liquid agent, and therefore the fin adds an area for a lot of heat convection. Copper is usually elect for tube and fin material because of its excellent thermal conduction and compatibility with water and ethanediol solutions. However, chrome steel is employed for tube and fin once it’s a necessity for the agent to be deionized water or corrosive fluids.

Different Heat Exchangers are as follows- 

Oil cooler flat tube heat exchanger

Lytron’s oil cooler flat tube heat exchangers also have the tubes and fin; but, the tubes are flat rather than spherical. This helps in minimizing pressure drop when oil or ethanediol is employed because of the agent.

The area of the flat tubes is additionally a lot larger than the area of the tubes in an exceedingly tube and fin device. The extra {surface ara|area|expanse|extent} of the tubes in associate degree oil cooler flat-tube device maximizes heat transfer once inadequate heat transfer fluids like oil or ethanediol are used.

These oil cooler heat exchangers include fin, flat tubes, a welded header with inlets and shops, and plates, as well as associate degree optional fan plate.

Plate fin 

Another style of device is a plate-fin device, which might offer air-to-air, air-to-liquid, liquid-to-air, or liquid-to-liquid cooling. Plate-fin heat exchangers include finned chambers separated by flat plates and are circuited in alternating hot and cold fluid passages.

Heat is transferred via fins within the passageways, through the centrifuge plate, and into the cold fluid via the centrifuge plate, and into the cold fluid via fin yet again. The warmth money dealer conjointly has manifold ducting, mounting brackets, and a frame.

Liquid to Liquid Brazed Plate

Lytron’s brazed plate heat exchangers also have plates, however, with a cloth pattern of grooves, stacked in alternating directions. This forms separate flow channels for two liquid streams in order that the two fluids are in direct contact. The warmth money dealer plates are brazed along at the perimeters and at a matrix of contact points between sheets. The liquid-to-liquid device may be compared to a shell and tube device that is employed in similar applications.


The thermal performance of warmth money dealer technologies will vary quite a bit. Thus when selecting a device, it is vital to grasp what performance is required in addition to what fluids are accessible for removal of warmth. It is also necessary to judge the whole system once electing a device, as there are a variety of concerns as well as the rate of flow, pressure drop, materials compatibility, and more.

Based on the results, the general heat transfer constant for the counter-current flows above the co-current flow. From the results obtained, the results have shown that the cold water exit temperature of the counter-current flow is above the co-current flow.

Hence, the counter-current flow is way a lot of potency than co-current flow. The results showed that the top rate of flow could cause the speed of heat transfer to increase. As a conclusion, the counter-current flow is a lot of potency than these-current flow and are the most popular to use within the transfer heat.
