Water-cooled cooling system
Thermal solutions

Water-cooled cooling system is an air conditioning method that can address the issue of high heat generation that occurs when high-speed CPU/GPU calculations are performed in AI and other applications, and can improve energy efficiency of data centers.

Sanoh's water-cooled cooling piping system, which uses technology that eliminates the risk of water leaks and is used in the cooling piping system of Fugaku (HPC), contributes to reducing power consumption in data centers, saving energy, reducing CO2 emissions, and improving the performance of high-performance servers.

Our products

Server rack water-cooled cooling device

Installed on the back of the server rack, the discharged heat passes through the pipe structure and is absorbed (heat exchange) by the water circulating inside the pipe.

Main applications

  • Cooling of server racks in data centers

Pipes and manifolds for cooling system

Pipes and manifolds for cooling system

Pipes and manifolds that connect the cooling system of super computer, which are significantly lighter than conventional rubber hoses and stainless steel manifolds.

Main applications

  • Cooling for super computer
  • Can also be used in cooling system that requires high-performances cooling functions for data center and communication equipment.

Resin tubes

Flexible and strong, they can be used to implement systems that take advantage of their light weight.

Main applications

  • Cooling water paths between the main pipes, manifolds, and water-cooled heat sinks (cooling plates)
  • In addition to resin tubes, we can also provide metal tubes that have excellent pressure resistance and strength.

Information on customized products

-water-cooled heat sink (cooling plate) –

water-cooled heat sink

We provide customized products according to customer specifications.

We are also developing a water-cooled heat sink (cooling plate) that directly cools CPUs/GPUs. We provide reliable piping specifications that have a proven track record in automotive parts, including tubes and connectors.

Basic specifications

We optimize the fin shape and create design according to customer specifications.

We have a track record of developing various fin shapes, and we will design water-cooled heat sink (cooling plate) that matches the cooling performance and pressure loss desired by the customer.

The balance between cooling performance and pressure loss can be adjusted by the fin shape of the heat exchanger. For example, you can select wave fins or pin fins to improve cooling performance, and straight fins to keep pressure loss low.

Water-cooled heat sink (cooling plate) performance

We are developing fins with high cooling performance. Compared to straight fins, we have a track record of developing high-performance fins even with a lower flow rate of cooling water.
When compared with the same pressure loss, the thermal resistance is reduced by 26%.
