Pulsating Heat Pipes

Also referred to as Oscillating Heat Pipes, Calyos is working hard to mature this newer technology.

Less reliance on gravity for operation.
The latent heat of vaporisation has a high heat transfer co-efficient.
Ability to operate in unique form factors (thin, 3D) with highly customised integration.

How do Pulsating Heat Pipes work?

Typical Applications

Regardless of the market segment the same applications require cooling.

Power Electronics

Power Electronics

  • Inverter
  • On-Board Chargers
  • Converter

Advancements in nano-technology (including GaN & SiC) are creating components with ever increasing heat density, combine this with the need to reduce packaging weight and volume and power electronics are increasingly difficult to thermally manage.

Calyos makes applying these two-phase technologies feasible.

By working side by side with our clients, Calyos can pair our knowledge and experience with our clients understanding of their application. This allows us to continue to develop innovative cooling systems that are viable in terms of mechanical design, cost and thermal performance for real-world applications.

Two-Phase Physics

Our experts enable us to produce
proprietary wick structures that maximize capillary pumping. We meticulously select fluids and fine-tune vaporization and condensation processes to deliver exceptional performance that Calyos is globally recognized for.

Modelling & Simulation

Calyos' advanced modelling capabilities integrate physics-based simulations with complex models derived from empirical test data. Two-phase modelling is not easy and this crucially ensures accuracy balancing theoretical precision and real-world validation.

System Design

Calyos' patents and exclusive know-how enable robust designs, that easily mechanically integrate with your application while remaining cost effective to manufacture, assemble, fill with fluid and install.

Manufacturing

In combination with our own facility and testing laboratory, Calyos has relationships with industrial partners in different regions and for different markets to meet the mass production needs for our clients.
