The intelligent air supply device includes an axial flow fan, a temperature and humidity sensor for monitoring the average temperature of the upper, middle and lower parts inside the cabinet and comparing it with the set value, and a temperature and humidity sensor for starting the axial flow. The temperature control switch of the fan and the control module for adjusting the size of the air supply; the air return unit is composed of a solenoid valve and a vertical pipe, and the air return unit is matched with the inter-row air conditioner.

There are at least two cabinets.

There are also cabinet equipment in the cabinet, and there are multiple pieces of cabinet equipment, and each piece of cabinet equipment is separated by a blind plate.

The end of the cabinet close to the front door is provided with an upper wind-shielding plate and a lower wind-shielding plate.

The inter-column air conditioner (6) is arranged at any position of the cabinet.

The cold air is sent to the front of the cabinet through the front door, the cabinet equipment draws in the cold air from the front of the cabinet, and exhausts the hot air from the rear of the cabinet equipment. Power cables enter the cabinet from the front half of the cabinet and lead to the PDU inside the cabinet for centralized power supply. The weak current cables enter the cabinet from the rear half of the cabinet and are led to the wiring unit inside the cabinet, which can realize the orderly and neat wiring and arrangement of the connecting wires in the cabinets. The inter-row air conditioner cools the center of the entire cabinet to ensure a uniform temperature in the center of the entire cabinet. The return air unit is matched with the inter-row air conditioner, and the opening of the return air duct is controlled according to the PID principle to effectively improve the cooling efficiency.

Compared with the prior art, the utility model has the following beneficial effects: the utility model solves the problem that the cabinet cannot be installed due to the insufficient floor height of the machine room, and can also automatically adjust the air volume according to the temperature, effectively improving the cooling efficiency and prolonging the use of equipment life. The utility model has the advantages of a closed hot aisle system, including rows of cabinets, strong wire slots, weak wire slots, intelligent air supply devices, inter-column air conditioners and return air units located on the top of the cabinets. When it is detected that the temperature inside the cabinet is higher than the set temperature, the axial flow fan cooling unit will be automatically started to work. At the same time, the front of the cabinet is a mesh door, and the back is a closed door. The isolation efficiency of cold air and hot air is high. Adjusting the air volume and dual control can make full use of the inter-row air conditioner, improve equipment efficiency, and ensure the reliable and safe operation of the data center.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and examples, but the protection scope of the utility model is not limited by the examples.

Example 1

As shown in Figure 1 and Figure 2, a cabinet with a multi-functional closed channel consists of a cabinet (1), a strong wire slot (2) and a weak wire slot (3) on the top of the cabinet, and an intelligent The air supply device (4), the air return unit (7), and the inter-column air conditioner (6) arranged on the cabinet, the cabinet is provided with a front door and a rear door, and the front door is a single or double opening mesh The back door is a single or double closed door; the strong wire slot and the weak wire slot both extend along the width of the cabinet and are installed on the top of the cabinet. The intelligent air supply device includes an axial fan for monitoring The temperature and humidity sensor that compares the average temperature of the upper, middle and lower parts with the set value, the temperature control switch for starting the axial flow fan, and the control module for adjusting the air volume; the return air unit is controlled by an electromagnetic Composed of valves and vertical pipes, the return air unit is matched with the inter-column air conditioner. There are at least two cabinets. The cabinet is also provided with cabinet equipment (11), and the cabinet equipment is in multiple pieces, and each piece of cabinet equipment is separated by a blind plate (10).
