We remove the risk of damage from costly water leaks using a dielectric fluid. Downtime is also reduced by removing the need for a pump.
By vaporizing a fluid our systems have the potential to be the most efficient form of heat transfer. For you this means the lowest thermal resistance.
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.
Our LHPs are unique in their ability to operate against gravity. This provides the only passive, two-phase solution to operate under such conditions.
Our systems can scale to your requirements. It doesn't matter the number of heat sources, thermal power, transport distance, or physical size.
The beauty of two-phase is the ability to harness the latent heat of vaporization, using it to power the cooling system, making it the most sustainable solution.
loop heat pipes
The porous wick structure inside the evaporator absorbs the incoming liquid and pumps it towards the baseplate creating the capillary pumping force to move fluid around the system passively.
The liquid evaporates as it contacts the baseplate as it is in contact with the heat source and therefore conducting heat. The vapour exits down the vapour line within the mechanical design.
The vapour continues to the cold source and condenses back into a liquid due to the temperature difference. The liquid then flows back to the evaporator down the liquid line.
This process continues indefinitely when heat is applied to the evaporator baseplate and the condenser (cold source) has a lower temperature than the heat source.

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.
The wick structure is the critical element Calyos has mastered and it provides the best pumping capability of any LHP evaporator made today.
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.
The micro-layer enhances the intimacy between the heat and the liquid maximizing vaporisation and therefore thermal performance.
