Direct Liquid Cooling System

Direct Liquid Cooling System

Direct-to-Chip (DLC) delivers coolant directly to high-heat components such as CPUs/GPUs. With a CDU and heat exchanger, coolant absorbs heat through cold plates and circulates in a closed-loop system.

Direct Liquid Cooling

Unlike immersion cooling, DLC cools only the target components through cold plates—without submerging the entire server.

  • Design & supply: cold plates, manifolds, hose kits, quick disconnect modules
  • Architecture support: In-Rack / In-Row CDU systems
  • Retrofit options that coexist with air cooling
  • Enables heat reuse and improves PUE

A sustainable choice for next-gen data centers

As AI servers push 300–400W+ per chip, air cooling alone reaches its limits. DLC reduces fan and air-handling load, improves chiller load and room temperature control, and boosts overall data-center efficiency.
