Axial Fans wall cooling meets the needs of 200kW Enclosure
Large and small Axial Fans walls meet the cooling needs of the cabinet
1.Large axial fan wall solutions
Definition:
A high-flow wall air conditioner is a large, modular "cold air barrier" typically installed at the end of a data center room. It provides direct cooling to the room by creating a large, cold air barrier, similar to the working principle of a room-based precision air conditioner. The high-flow wall air conditioner uses powerful airflow to cover the entire room, ensuring that cold air reaches the air inlet of every piece of equipment.
Technical Features:
High Air Volume, Long-Distance Air Delivery: The core technology of a high-flow wall air conditioner is its ability to generate high air volume and high pressure, typically around 150 Pa. This cold air can penetrate the entire room and cover long distances (10 meters or more), ensuring that every cabinet receives adequate cooling.
Aisle/Room Coverage: Suitable for large-scale zone cooling, typically used for entire computer rooms or aisle-level cooling, to address uneven cooling within the room.
Modular Design: A high-flow wall air conditioner consists of multiple fan modules, whose length and air volume can be adjusted as needed. This allows for flexible deployment based on the size and needs of the room.
Combined with Hot Aisle Containment: High-air walls are often used in conjunction with hot aisle containment systems to effectively reduce temperatures through diffuse air distribution. Additionally, ceiling return air can effectively improve air return efficiency.
Energy Savings: By increasing the utilization rate of cold air and reducing fan resistance, the air conditioning system's operation is optimized, achieving higher energy efficiency. Compared to traditional precision air conditioners, high-air wall systems can significantly reduce energy waste.
Applicable Scenarios:
Suitable for large computer rooms: particularly data centers, power distribution rooms, and other environments that require multiple cabinets, with a single cabinet power consumption of no more than 8kW.
Large-Scale Cooling Requirements: Suitable for environments where constant temperature and humidity must be maintained over a large area, particularly in aisles and open areas within the computer room.
2.Small axial fan wall solutions
Definition:
A small air wall unit is a small, precision cooling device typically installed at the front or back of a cabinet. It provides targeted cooling airflow to a single cabinet or multiple cabinets, similar to a backplane air conditioner. The core design of a small air wall unit is to precisely deliver cool air to the cabinet's air inlet or extract hot air from the cabinet's back, thereby addressing the cooling needs of high-density cabinets.
Technical Features:
Precise Air Delivery: A small air wall unit uses a close-range air delivery method, delivering cool air to the cabinet's air inlet or heat extraction vents at the cabinet's back with near-zero distance. Air pressure is typically around 20 Pa, significantly lower than that of a large air wall unit, making it suitable for localized cooling needs.
Cabinet-Level/Local Coverage: A small air wall unit primarily addresses cooling issues at the individual cabinet or row level. It is suitable for cooling high-power cabinets and offers significant advantages in optimizing PUE (Power Efficiency Unit).
Flexible Installation: Due to their compact size and simple installation, small air wall air conditioners can be installed directly next to the target cabinet, eliminating the need for major adjustments to the overall computer room layout, offering enhanced flexibility.
Plug-and-Play: Most small air wall air conditioners come with independent control systems or can be easily integrated with the computer room's existing monitoring system. This plug-and-play design simplifies device deployment and management.
Energy Saving: Through precise, point-to-point cooling, small air wall air conditioners offer low energy consumption. Their low air pressure and concentrated air volume effectively reduce energy consumption in power-intensive cabinets.
Applicable Scenarios:
Suitable for high-density cabinets: Especially where individual cabinets require high power (≤25kW) and require precise cooling, such as high-performance computer cabinets or high-density servers in data centers.
Suitable for Localized Cooling: Targeted cooling of specific cabinets effectively addresses localized hotspots, especially when traditional air conditioners cannot meet high-power dissipation requirements.
