Based on our analysis the market is expected to grow at a CAGR of 13.2% from 2024 – 2030 timeframe. Some of the prominent trends that the market is witnessing include, expansion of metal baffles, twisted tube heat exchanger technology and reinvention of heat transfer.

Global Aircraft Heat Exchanger Market: Market Dynamics

Heat exchangers play a vital role in mission-critical aviation and several other aerospace applications. Increasing energy demand among oil & gas, petrochemical and power industry alongside rising investments toward up-gradation of existing aviation, space and energy infrastructure has propelled the heat transfer equipment demand.

For instance, heat exchangers are a significant component for the optimal performance of jet engines; essential to the accurate running of aircraft electronics; and important to a satellite’s ability to achieve a multitude of purposes without overheating.

On the other hand, the issues related to heat exchanger fouling are likely to obstruct the profit boundaries. In addition, increasing fleet commercial and combat aircraft and rising demand for effective cooling and heating in commercial aircraft will further boost for the aircraft heat exchanger market.

Impact of COVID-19 on Aircraft Heat Exchanger

Aircraft heat exchanger manufacturers are compelled to shut down production operations due to government-imposed lockdown to monitor the spread of COVID-19 worldwide. Aircraft manufacturers are witnessing operational problems due to supply chain disruption caused by the restrictions on transportation in the wake of COVID-19 pandemic. Maintenance, repair, and overhaul (MRO) services of aircrafts are adversely affected due to lack of supply of raw materials & essential components owing to the government schemes against the COVID-19 outbreak. R&D of aircraft heat exchangers, majorly for the military applications is stalled due to shortage of labor force caused by the government-imposed lockdown amid COVID-19 scenario.

By Application

Electronic Pod Cooling Segment Dominate the Market in 2024

The electronic pod cooling segment made huge revenue in 2024 and growing its prominence during the forecast period. Heat exchangers are used to bring down the temperature of hydraulic fluid and is placed inside the fuel tank. Electronic Pod cooling involves cooling of electronic devices such as IC packages, chips and many other airtight packaged devices. With rising demand of automation, more electronics package needs to be fitted in smaller and tighter space and thus it is projected to escalate the demand for electronic pod cooling during the forecast period.

By Geography

Asia Pacific Region is Leading in the Global Market Place

Asia Pacific is likely to have a huge demand in the forecast period in terms of research and development (R&D) activities, deployment, and also due to the presence of some of the key market players. The major countries under this region are India, Japan and China. Factors like inexpensive and high skilled personnel for manufacturing of aircraft heat exchangers is boosting the market in Asia Pacific region.
