Micro-channel heat pipes for
Batteries

MCHP-BT

Simple, lightweight and ultra-efficient heat transfer device.
cost effective

UHP-BT has a great cost to performance ratio. This can enable the adoption of new features such as ultra-fast charging that demand advanced cooling solutions.

Scalable design

The design of our UHP-BT solution can easily be modified based on the mechanical design of your battery pack. Calyos can also produce a double sided cooling solution.

ultra reliable

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

Long lasting

We produce systems with design lifetimes of up to 40 years. This fit and forget approach comes from our technology's history in the space industry.

100% PASSIVE

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

Adapt the system to your needs

No application is the same, hence each of our solutions is adaptable to your specific needs and design. Below we outline how several key parts of the solution can be modified to suit the thermal challenge you face.

The Evaporator Section

The heat pipe section that is embedded inside the battery pack is the evaporator section. It can be as long as needed, and feature bends to maximise contact with the heat source. A TIM is recommended to maximise the performance.

The Cross Sectional Area

The heat pipe is made from extruded aluminium and the cross section extrusion can be customised to meet the available space in your design. More or less channels can be added depending on the final mechanical design.

the condenser section

This section at the top of the heat pipe can dissipate the heat into the air using a finned heat sink, or by conduction into a water cold plate. The size of the condenser section is the critical factor determining how much heat can be removed.
