What Are the Different Types of Heat Exchangers?

---

Heat exchangers are used to transfer heat from one source to another. Thermal energy is transferred from one source to another without water and gas coming into contact with each other. These heat exchangers are commonly used in a variety of aircraft components. In aviation, flat tube and plate-fin heat exchangers are the most commonly used in aviation. These components must be properly cleaned in order to function smoothly.

Because they will be used at high altitudes, temperature, air density, and pressure resistance all need to be taken into consideration. The fan component used in the heat exchanger must also be carefully selected since more airflow is required to remove heat in higher altitudes where air density is much lower.

Liquid cooling tends to perform better than air cooling alone. Liquid cooling is also quieter and less vulnerable to the problems associated with high altitudes. It requires less power and weighs less because there is no need for a large fan or wide spacing.

Plate-fin heat exchangers use plates and finned chambers in order to transfer heat. They can be used for air-to-air, air-to-liquid, or liquid-to-liquid cooling. Considering their weight, this type of heat exchanger part performs very well.

Flat tube heat sink parts consist of several flat tubes that are vacuum-brazed in between. These tend to be less expensive than plate-fin designs.

There are high standards when it comes to cleaning heat exchangers. This is due to all the strict and stringent safety requirements that govern aviation. The amount of buildup can be estimated based on past experiences as well as the number of hours flown.
