KRN Heat vs Aeroflex Which Data Center Cooling Stock Could Create More Wealth By 2035?
Published: June 2026 | By: FinPixie Research Desk
Everyone is chasing AI software. The hidden opportunity may lie in the companies preventing AI servers from overheating.
🔥 The Problem Nobody Talks About
Artificial Intelligence is creating a new industrial revolution. Every AI query, every AI image, every AI model requires enormous computing power.
But computing power creates heat. And heat is becoming one of the biggest bottlenecks in the AI era.

More Cooling Infrastructure
The future of AI may not be decided only by chips and software. It may also be decided by who can remove heat most efficiently.
📈 Why Cooling Is Becoming Critical
A decade ago, most data-center racks consumed around 5–10 kW. Modern AI racks can consume 50–100+ kW. That means dramatically higher cooling requirements.
Every increase in computing density creates a disproportionate increase in cooling requirements.
❄ Air Cooling vs Liquid Cooling
| Factor | Air Cooling | Liquid Cooling |
|---|---|---|
| Cost | Lower | Higher |
| Efficiency | Moderate | Very High |
| Complexity | Low | High |
| AI Readiness | Good | Excellent |
This transition is exactly why investors have started paying attention to companies like KRN Heat and Aeroflex.
🌎 Understanding The Cooling Ecosystem

💰 Could KRN Become A Multibagger?
The answer depends on whether KRN can move from being viewed as an HVAC supplier to being recognized as a critical thermal management player in India's AI infrastructure ecosystem.
If the company captures even a modest share of future cooling infrastructure spending, the market opportunity could be significantly larger than its current business size.
KRN Heat appears to be a strong indirect beneficiary of the AI cooling megatrend, particularly if air-cooling and hybrid-cooling solutions remain dominant over the next decade.
🚀 Aeroflex: The Liquid Cooling Contender
If KRN Heat represents the traditional and hybrid cooling side of the opportunity, Aeroflex represents something potentially more disruptive:
As AI workloads become more intensive, traditional air cooling begins to face limitations. The next generation of AI infrastructure is increasingly exploring liquid cooling technologies to improve efficiency, reduce energy consumption and manage higher rack densities. This is where Aeroflex enters the story.
🏭 What Does Aeroflex Actually Do?
Aeroflex manufactures specialized metallic flexible flow solutions used across multiple industries.
