The freshness of deep-sea fish declines every minute once they are taken out of seawater and sent to warehouses. Traditional refrigeration equipment struggles with slow freezing and unstable temperatures, where large ice crystals rupture fish cells, leading to excessive water loss, loose texture and deteriorated flavor after thawing. To solve this industry pain point, Yair’s low-temperature quick-freezing solution adopts AI precision temperature control of ±0.5℃ and high-efficiency hot-gas defrost technology, delivering around 50% energy savings. As a reliable cold room refrigeration unit, it perfectly maintains the tender texture and original color of deep-sea fish even under high summer temperatures. Deep-sea fish are rich in premium protein and unsaturated fatty acids yet extremely perishable. In summer heat above 30℃, accelerated enzyme activity and bacterial reproduction rapidly degrade seafood freshness, making fast and stable refrigeration indispensable for standard cold chain preservation.

With the accelerated large-scale and intelligent upgrading of the cold chain logistics industry, sectors including fresh food logistics, pharmaceutical cold chain and low-temperature processing have raised higher standards for cold storage in terms of storage density, operational efficiency, safety stability and traceability capability. Traditional cold warehouses are plagued by wide operation aisles, low space utilization, high manual operation risks and high equipment failure rates in low-temperature environments, gradually becoming core bottlenecks restricting the cost reduction and efficiency improvement of cold chain warehousing. Against this backdrop, the intelligent four-way shuttle warehousing solution tailored for extreme low-temperature scenarios has become a mainstream choice for the new generation of cold storage intelligent upgrading, featuring high density, high flexibility, superior stability and full intelligence. As a reliable pharmaceutical cold room refrigeration unit supporting system, it delivers core support for the digital and unmanned transformation of cold chain warehousing, fully meeting the stringent storage and safety requirements of pharmaceutical and fresh cold chain scenarios.

AI and high-performance computing (HPC) workloads have pushed data center rack power density far beyond the traditional limits of air cooling. Rack power density has surged from the original 5–10 kW to 30 kW, 50 kW or even higher levels, making conventional air cooling increasingly inefficient and inadequate. More operating power generates massive heat, creating an urgent demand for efficient heat dissipation solutions. Liquid cooling captures heat directly at the heat source with far higher thermal conductivity than air, effectively solving the heat dissipation bottleneck of high-density racks. As a mainstream retrofitting and upgrading solution for existing data centers, the rack mount rear door heat exchanger perfectly bridges the gap between traditional air cooling and advanced liquid cooling, delivering balanced performance, cost-effectiveness and operational flexibility for medium and high-density server racks.

Driven by the explosive growth of large-scale AI models and high-performance computing, computing power density keeps rising continuously. Traditional air-cooling technology has hit its thermal dissipation ceiling, and liquid cooling is evolving into a standard configuration for data centers. At the heart of the complete liquid-cooling system sits a pivotal hub device: the CDU, or Coolant Distribution Unit. This article elaborates on its definition, core functions, classification, selection principles and application scenarios to help you fully understand this “heart-like” component of liquid-cooling infrastructure. As a critical transitional hardware for retrofitting legacy computer rooms without pre-installed chilled-water pipelines, the data center air liquid cooling CDU bridges conventional air-cooling and high-efficiency liquid-cooling, delivering stable thermal management for computing hardware under varying site constraints.

Driven by the rapid growth of artificial intelligence and the AI industry, data centers are confronted with mounting computing-power burdens. Conventional air-cooling solutions can no longer satisfy the thermal dissipation requirements of high-density computing hardware. As enterprises construct intelligent computing centers and renovate legacy computer rooms, they set higher standards for cooling capacity, operational stability and energy consumption. Liquid cooling has emerged as a major industry trend. The 4U Coolant Distribution Unit (CDU), a core rack-level liquid-cooling component, enables ultra-low PUE operation and has become essential for next-generation high-density computing rooms. Optimized for compact on-site deployment, modern rack cooling hardware delivers localized coolant allocation inside standard cabinets, cutting pipeline resistance and mitigating leakage risks for AI-intensive computing deployments.

With the rapid growth of AI models, supercomputing and high-density server cabinets, single-rack power density in data centers has reached 80kW, 100kW and beyond. Restricted by low efficiency, high noise and excessive energy consumption, traditional air cooling can no longer support high-power computing hardware. As a result, liquid cooling has become the preferred cooling solution for modern intelligent computing centers. As the core hub connecting the entire cooling loop, the CDU determines the efficiency, stability and service life of liquid cooling systems, making it essential for liquid-cooled data centers. The air liquid CDU cooling unit enables seamless upgrades from legacy air cooling to liquid cooling, delivering reliable, low-energy heat dissipation for high-density computing scenarios.

With the large-scale deployment of AI computing and supercomputing data centers, liquid cooling has evolved from an alternative solution into a mainstream industry cooling technology. Most users focus on CDU liquid supply capacity, temperature control accuracy and flow resistance indicators, while easily overlooking a critical process that determines long-term equipment reliability: factory cleaning and drying testing. Many common on-site faults, including cold plate blockage, pipeline corrosion, turbid coolant and abnormal system flow resistance, can be traced back to residual contaminants and trapped water inside pipelines. As a professional data center cooling CDU supplier, we clarify the standardized CDU cleaning and drying procedures, qualified evaluation criteria and common pitfalls to help the industry eliminate hidden risks in advance for stable long-term liquid cooling operation.

Many industry practitioners simply regard liquid cooling as piping water directly to server chips. In fact, the 2.5MW Coolant Distribution Unit (CDU) is a highly integrated heat exchange and circulation system with sophisticated structural design, far more complex than basic piping layouts. As AI computing power density continues to surge, single-rack power load has risen from several kilowatts to hundreds of kilowatts, completely breaking the heat dissipation limit of traditional air cooling and making liquid cooling a standard configuration for large-scale data centers. Serving as the core heart of the liquid cooling system, the CDU efficiently and stably transfers heat generated by server hardware to facility-side chilled water for dissipation. A clear understanding of CDU structural design is the premise of standardized liquid cooling infrastructure construction, covering piping routing, joint selection, equipment load-bearing and non-stop maintenance design. The high efficiency CDU for data center delivers stable, high-power heat exchange capacity, solving the core heat dissipation pain points of high-density AI computing clusters.

As liquid cooling rapidly scales across modern data centers, many operators oversimplify the CDU as a basic heat exchange cabinet. In fact, the cold plate CDU serves as the critical intermediate hub linking primary chilled water loops and secondary server cold plate circuits, delivering core functions including heat transfer, loop isolation and balanced coolant distribution. Most on-site operational risks stem from insufficient understanding of its internal structure, component matching and design logic. This article systematically dismantles the CDU’s six core modules, explaining their functional principles, selection criteria and standardized maintenance guidelines for reliable liquid cooling deployment.
