Cold/hot aisle containment working principle

Hot/cold aisle containment is a technology used to reduce the temperature of equipment that generates heat due to work. Mainly used in data center computer rooms. Enterprise data center computer rooms generally face equipment with high heat density and high power consumption, insufficient space in the computer room and cabinets, and computer room planning cannot keep up with the growth of business needs. In order to meet the rising heat dissipation requirements of data center computer rooms, the equipment of computer room air conditioners has been continuously increased and replaced. However, there is still a local heat island problem inside the computer room. Cold air and hot air are directly mixed, resulting in a huge waste of cooling energy.

As the power consumption of server equipment continues to increase, the cooling capacity required by the cabinet will need to be greatly enhanced. Reasonable use of the cold aisle solution can greatly improve the heat dissipation capacity of the data center and fully and effectively use the cabinet and computer room space. The cold/hot aisle closed system is based on the principle of separation and orderly flow of hot and cold air. The cold air is blown out from under the elevated floor. , entering the closed cold pool channel, the equipment at the front of the cabinet sucks in cold air, and after cooling the equipment, the hot air is formed and discharged from the back of the cabinet to the hot channel. ​

The gas in the hot aisle quickly returns to the air conditioner return vent. The closed turbine rear door of the cabinet collects hot air and is seamlessly connected to the ceiling through vertical air ducts. The hot return air is completely isolated from the cold. Therefore, the utilization rate of internal air conditioning is improved, more heat generated by the equipment is taken away, and the temperature of the equipment is reduced.
