The cold channel is a solution for cooling the server cabinet in the computer room. The cold channel is composed of the top skylight module, the normally closed double door, the frame installation unit, the auxiliary installation parts, etc. the cold channel is closed, so that the cold air does not leak to other areas, avoids mixing with the air after heat exchange, improves the refrigeration utilization rate, effectively reduces the energy consumption in the computer room, and extends the service life of the equipment.
The cabinet adopts a “face-to-face” layout. The channel in the middle of the cabinet adopts a ventilated floor. The cold air sent out by the room level air conditioner enters the channel in the middle of the cabinet through the underfloor space through the ventilated floor, forming a “cold channel”; Because the cold channel is closed, the cold air flow cannot further spread to the upper part of the channel and both ends of the channel, so it all enters the cabinet; The cold air absorbs the heat dissipation of IT equipment in the cabinet and becomes hot air to be discharged. It returns to the room level air conditioner along the ceiling. The hot air is cooled again in the air conditioner and sent out to enter the next cycle.
Suitable for large machine room scenarios, single cabinet power supports 1kW ~ 10kW, total power supports 24kw ~ 120kw, and total number of cabinets is 6 ~ 30
The unit is of modular design and is installed on the top of the front of the cabinet. Each unit can be installed independently and connected with adjacent units for easy disassembly and replacement.
The machine room adopts centralized cooling mode. The cold air enters the channel through the electrostatic floor at the bottom of the cold channel, and the hot air enters the air conditioner through the return air port at the top of the machine room
The frame and the horizontal support of the cabinet are connected with special connection holes to increase the overall stability; In addition to strengthening the channel itself, it also needs to play a convenient expansion function; The mounting holes on the mounting bracket shall be arranged in a grid of ≥ 25mm for universal assembly.
No threshold design, convenient for barrier free installation of equipment.
Each movable skylight can realize fire linkage. When a fire signal is received, the skylight will automatically open and fire gas can enter the channel to extinguish the fire.
Each channel is equipped with an emergency stop switch, which can be physically opened by an emergency button to improve safety and reliability
The closed window of the channel is made of glass, which is coordinated and beautiful with the computer room as a whole. The glass used conforms to the standard of GB 15763.2-2005 safety glass for buildings, so as to prevent the impact of glass crushing on the data room and maintenance personnel.
The movable door is designed to be normally closed, and equipped with a buffer automatic closing device. Push pull handles are set on both sides to open flexibly.
The door and the frame are sealed with wool, with tight tightness, which can effectively prevent the cold air flow from escaping.
Password access control is installed on the outer side of the movable door frame of the channel, and button switches are installed on the inner side. The wiring channel is reserved in the door frame assembly, which has the functions of hiding and wiring.
The opening angle of the skylight can be flexibly adjusted according to the environment of the machine room
All power distribution, refrigeration and business operation surfaces are on the same side, which is convenient for maintenance by operation and maintenance personnel
Excellent airflow optimization design, avoid cold and hot airflow mixing, and reduce energy consumption cost
The mechanical, chemical and electrical properties of the materials, fasteners and seals used for the cold channel unit comply with Chinese national standards, communication industry standards and relevant IEC standards.
Surface treatment: degreasing, pickling, phosphating, plastic spraying (color can be customized)
Green and environmental protection, the product material and surface spraying have reached the national non-toxic and harmless spraying standard
Standardized parts, de engineering and overall delivery. It can be matched in real time according to business development and rapidly expanded.
