With the rise of AI, HPC, and edge computing, data center heat loads continue to climb, making traditional air cooling systems increasingly insufficient. Kaori’s brazed plate heat exchangers (BPHE) offer excellent thermal performance, compact design, and high reliability. Supporting both single-phase and two-phase liquid cooling applications, Kaori BPHEs help you achieve lower PUE, higher computing efficiency, and greater sustainability.

Solutions

Kaori's heat exchangers are widely used in the following liquid cooling architectures, helping data centers meet the needs of high heat density and diverse deployment:

In-Rack CDU

Cooling close to the heat source for precise liquid cooling within the rack.

• Suitable for high-power-density servers
• Easy for modular integration
• Precise temperature control, quickly removing heat from sources such as CPU, GPU, memory, or VRM

In-Row CDU

Provides centralized cooling, meeting the heat dissipation needs of multiple racks simultaneously.

• High heat dissipation efficiency, optimized space utilization
• Suitable for large-scale and high-heat-density environments
• Precise flow control, supports hot/cold aisle containment designs

Immersion Cooling

Immerses servers completely in a non-conductive fluid for ultimate heat dissipation performance.

• Supports single-phase and two-phase systems
• Effectively reduces PUE, saving space and energy
• Applicable to standalone or built-in CDU

Single Server Cooling

Designed specifically for edge computing and modular architectures, providing an independent liquid cooling loop for each server.

• Compact size, suitable for high-density deployment
• Fast heat removal, high cooling efficiency
• Optional all-stainless steel material, suitable for high-purity application environments
