Heat Pipes

Beautifully simple,
incredibly capable.
ultra-reliable

With no moving parts, our solutions are extremely reliable and inherently maintenance free. Therefore they are ideal for reliability critical environments.

self regulating

Our systems simply operate when heat is applied, adjusting their performance depending on the amount of heat to dissipate. There is no control system to potentially breakdown or fail.

Ultra efficient

By vaporising a fluid our systems have the potential to be the most efficient form of heat transfer. For you this means the lowest thermal resistance.

Cost effective

Once the specification is validated, heat pipes are a simple solution with a low unit cost, proving them to be a popular option for static applications.

100% Passive

The beauty of two-phase is the ability to harness the latent heat of vaporisation, using it to power the cooling system is the most sustainable solution.

heat pipes

how do they work?

01

Vaporisation

When heat is applied to a section of the heat pipe it causes the liquid inside to vaporise.

02

Vapour Flow

This vapour then flows up the center of the tube as it is the path of least resistance against gravity.

03

Condensation

The vapor condenses back into a liquid due to the temperature difference of the cold section.

04

Capillary Return

The wick structure on the inside of the tube assists the liquid in returning to the heated section for the process to repeat.

heat pipes

our strengths

Our ability to innovate is fundamental to our mission. Applying our world-leading two-phase knowledge and experience we design the best passive thermal management solutions.

wick structure

The wick structure enables the return of the liquid. In traditional heat pipes it can be a grooved structure, unlike loop heat pipes that are more complex.

fluid

Calyos typically use a safe, green, dielectric refrigerant r1233zd(E) as its Global Warming Potential is <1. Plus we have experience using other fluids as required for different applications.

system design

Our skillset is in customizing two-phase solutions to maximize the performance while making sure they are non-invasive and easy to adopt.

heat pipe for power electronics

HP-PE

Ideal for static applications such as charging infrastructure, our unique heat pipe solution is a little different from traditional heat pipes. Thanks to our expertise in two-phase technologies we are able to use our grooved wick structure in combination with a unique mechanical design to provide the best cost to performance ratio.
