Servers

Advancements in nanometer lithography combined with demanding workloads from AI are resulting in computer processors that are producing more waste heat at an increased density.

Smaller nanometer lithography is resulting in extremely high heat flux's.
Higher power processors are dissipating more and more heat.
Restricted space within and above each server to maximise rack density.

What solutions does Calyos offer?

Calyos' primary solution for cooling servers uses our Loop Heat Pipe technology.

Loop Heat Pipes

LHPs provide the ability to not only handle very high heat flux, but also to transport heat over long distances.

Why this solution?

Our technology has long been deployed in server environments and more recently we have expanded into the telecommunications market. Calyos utilizes standard components to build a solution specific to your mechanical design, with our inherent fit-and-forget reliability.

Dielectric fluid poses no risk of short circuits.
Ability to cool the latest CPUs, GPUs, FPGAs and ASICs.
Transport heat to available space inside the server.

How can you customize this solution?

Evaporator Size & Mounting

The size and mounting plates can be customized to your processor and socket.

Number of Evaporators

Multiple evaporators can be configured together using parallel lines.

Line Routing

Lines can be routed around other components on the PCB, plus flexible lines allow for serviceability.

Condenser Type & Size

Different exchanger technologies like skived fins or parallel channels can be used as needed.

What about a passively cooled rack?

Calyos has begun developing a passive technology cooling system for data center racks. The system transports the heat to the top of the rack where it can be exchanged with the facility water system (FWS).

Only a passive CDU (no pumps) is used to dissipate the heat from the rack into the FWS.
No pre-heat affect and no unneccessary pumping of fluid when load is low.
Patented technology based on capillary jet loop is a unique invention from our CTO.
