Development of Thermal Management Systems

The growing demand for expansive data storage and computing capacity confronts data centers with a critical challenge. Traditional cooling solutions struggle to cope with rasing heat densities. The RDx system, functioning as a rear-mounted radiator door on the rack, facilitates efficient heat exchange with cooling gas or water. This minimizes the risk of hot air recirculation within the rack, ensuring optimal operating conditions for data servers.

Product Features & Technical Specifications

Liquid cooling necessity threshold - 250-400W per server: liquid cooling becomes beneficial; above 400W: only viable cooling solution for AI and HPC

Why Liquid Cooling

  • When server power is 250-400W, the liquid cooling is starting to make sense.
  • When server power is above 400w for servers, the liquid cooling is the only choice.

Coolant Distribution Units (CDUs)

  • Standard 19inch rack oriented design, easier Transaction to existing layout and data center plan.
  • Up to 100kW cooling capacity in 4U space saving dimension.
  • Mature smart control system can control, monitor, and access the key working status locally and remotely.
  • Easy to connect to IT server with self-sealed quick connector, plug and play.
  • Top level components ensure high reliability and long working life.
ByteCool liquid cooling manifold and self-sealed quick connectors - stainless steel manifolds with dry disconnects, vertical/horizontal adaptable for cold plate loops

Manifolds & Connectors

  • Manifolds are made of reliable stainless steel for rugged durability.
  • Combined with dry disconnects, self-sealed quick connectors, plug and play. Providing easy interface between cold plate loops in the servers and CDU.
  • Flexible input and output loops customization, support vertical/horizontal adaptive.

High Efficiency Heat Rejection

ByteCool free cooling chiller for liquid cooling - natural cooling mode for low PUE, optional wet-film evaporative pre-cooling, uses R407C or R134a refrigerants

Free Cooling Chiller
