In today's explosive growth of AI and cloud computing, the power density of data center cabinets continues to rise, and the cooling mode of traditional room-level air conditioning "big horse-drawn cars" can no longer meet the demand - frequent local hot spots, high energy consumption, and difficult to optimize PUE have become pain points in the industry.

Haiwu has innovatively launched CDA rack air conditioners, which are specially designed for high heat density scenarios, with 5U ultra-thin body, 5kW powerful cooling, and intelligent dynamic temperature regulation as the core advantages to achieve cabinet-level precise temperature control and help data centers move towards an efficient, low-carbon, and reliable future!

[Why choose Haiwu CDA rack air conditioner?] 】

1. Close to the heat source and accurately eliminate local hot spots

• Direct cooling design in the cabinet: Installed directly on the side/top of the cabinet, the cold air is delivered to the server at zero distance, avoiding the efficiency loss of traditional air conditioners "long-distance cooling".

• Top temperature management: Real-time monitoring of temperature distribution in the cabinet and intelligent adjustment of air supply strategies to eliminate the risk of high temperature downtime.

2. Extremely space-saving, 5U height carries 5kW cooling capacity

• Compared with traditional air conditioners, which occupy floor space in the data center, CDA only requires a 5U cabinet height (about 22cm) to maximize the deployment space of IT equipment.

• It is suitable for various high-density scenarios such as distributed computer rooms, modular data centers, and blade server cabinets.

  

 3. Intelligent energy saving, dynamically matching load demand

• Inverter compressor + EC centrifugal fan: adjust the refrigeration output in real time according to the cabinet load, and reduce energy consumption by 30%+ compared with fixed-frequency air conditioners.

• Electronic expansion valve + PID control: 0.1°C precise temperature control to avoid energy waste caused by overcooling.

4. Safe and reliable, multiple protection design

• Anti-condensation backflow: Unique drainage structure eliminates the hidden danger of water leakage inside the cabinet.

• Wide voltage adaptation (±20%): copes with power grid fluctuations and ensures stable operation 7×24 hours a day, .

【Typical Application Scenarios】

✅ Edge computing nodes: The cooling conditions of small computer rooms are limited, and CDA provides a "plug and play" temperature control solution.
✅ AI server cabinet: When the power of a single cabinet exceeds 10kW, multiple CDAs can be deployed in parallel.
✅ Communication base station: -40°C~55°C full climate adaptation to meet the harsh outdoor environment.

[Social value: the pioneer of the "carbon" road of green data centers】

• Reduce PUE: Reduce the redundant energy consumption of air conditioning systems through precision refrigeration, helping data centers achieve the PUE ≤1.25 requirement of "East Data and West Computing".

• Reduce carbon emissions: A single CDA saves about 12,000 kWh of electricity per year, which is equivalent to reducing 7.5 tons of carbon dioxide.

• Policy compliance: The advanced technology of the national green data center is supported by energy-saving subsidies in many places.
