[0002] As the power consumption of server equipment continues to increase, the heat dissipation capacity required by the cabinet will need to be further strengthened. The rational use of cold channel sliding door devices and cold channel sliding door control systems can improve the heat dissipation capacity of the data center, effectively use the cabinet and computer room space, and improve the internal cold air utilization rate, take away the heat of the equipment, and reduce the temperature of the equipment.

Especially in emergency situations, such as fires, power outages, or other emergencies, it is critical to ensure that personnel can be evacuated quickly and safely. Traditional data center cold channel sliding door devices usually use sliding door designs, relying on slide rails to open and close the door leaves. In the event of an emergency, it is impossible to evacuate quickly, and the safety of personnel cannot be guaranteed, which poses a great safety hazard.

[0004] In order to solve the above problems, the present invention proposes a new type of cold channel sliding door device for data centers, which can not only realize the smooth movement of the door leaf through the slide rail under normal circumstances, but also ensure that the door leaf can be quickly opened by rotation when the slide rail fails, ensuring the safe evacuation of personnel. In addition, the device also provides more operational flexibility and maintenance convenience, and improves the reliability and safety of the system. By introducing a dual motion mechanism and redundant design, the present invention significantly improves the response capability of the cold channel sliding door device of the data center in emergency situations.

[0050] Specifically, the door leaf 140 in the cold channel sliding door device 100 of the data center has two operating states. When the sliding door device is operating normally, the door leaves 140 on both sides of the base 110 are opened and closed, which is the first state; when the sliding door device is operating abnormally, that is, when encountering an emergency situation, the door leaf 140 is converted to the second state.

[0051] See also Fig. 9 , Fig.11 , Fig.12 and Fig.14 , Fig. 9 The effect diagram of the door leaf rotating with the first connecting member 151 and the second connecting member 152 as the axis, the first connecting member 151 on the door leaf 140 is fixed on the first screw rod 141a, and the second connecting member 152 is fixed on the third slide rail 142a; Fig.12 The effect diagram is that the door leaf 140 rotates with the first connecting member 151 and the second connecting member 152 as the axis, the first connecting member on the door leaf 140 moves on the first screw rod, and the second connecting member moves on the third slide rail.

[0052] When the first slide rail 111 fails, the second connector 152 stops at the fault position of the first slide rail 111, and the first connector 151 and the second connector 152 are on the same straight line. At this time, the second connector 152 is fixed at the fault position due to the failure of the first slide rail 111, and the first connector 151 is relatively fixed on the second slide rail 131, and the door leaf 140 is converted to the second state, the first connector 151 slides on the first screw rod 141a, and the second connector 152 moves on the third slide rail 142a.

[0053] See also Fig.15 , Fig.16 and Fig.17 , Fig.15 for Fig.12 Schematic diagram of a single-sided structure, the door leaf 140 rotates around the first connecting member 151 and the second connecting member 152 as the axis, the first connecting member on the door leaf 140 moves on the first screw rod, and the second connecting member moves on the third slide rail.

[0054] When the second slide rail 131 fails, the first connector 151 stops at the fault position of the second slide rail 131, and the second connector 152 is on the same straight line as the first connector 151. At this time, the first connector 151 is fixed at the fault position due to the failure of the second slide rail 131, and the second connector 152 is relatively fixed on the first slide rail 111, and the door leaf 140 is converted to the second state, the second connector 152 slides on the third slide rail 142a, and the first connector 151 moves on the first screw rod 141a. At the same time, the door leaf 140 can rotate about the axis formed by the second connector 152 and the first connector 151, that is, the door leaf 140 is converted from a mobile door to a sliding door, which is convenient for the internal personnel to quickly escape from danger.

[0055] See also Figure 5 , Figure 6 , Figure 7 and Figure 8 , the first connecting member 151 and the second connecting member 152 are respectively provided with locking components 160, and the two sets of locking components 160 are controlled by the same control module to achieve the same direction movement and synchronous opening and closing; when the door leaf 140 is in the first state, the locking component 160 is closed, and the door leaf 140 slides on the first slide rail 111 and the second slide rail 131; when the door leaf 140 is in the second state, the locking component 160 is opened, the first connecting member 151 slides on the second slide rail 131, and the second connecting member 152 slides on the first slide rail 111, and the first connecting member 151 and the second connecting member 152 move synchronously; the first connecting member 151 slides on the first screw rod 141a, and the second connecting member 152 slides on the third slide rail 142a, and the first connecting member 151 and the second connecting member 152 move synchronously; the door leaf 140 rotates with the first connecting member 151 and the second connecting member 152 as the axis.

[0056] In this embodiment, seamless switching of the door leaf 140 between the sliding mode and the rotation mode is achieved through the synchronous locking and unlocking mechanism of the first connecting member 151 and the second connecting member 152; the locking components 160 are controlled by the same control module to ensure that the two sets of locking components 160 move in the same direction and open and close synchronously, thereby improving the reliability and consistency of the system.

[0057] Specifically, the first connecting member 151 and the second connecting member 152 are respectively provided with a locking member 160, and the two sets of locking members 160 are controlled by the same control module to achieve movement in the same direction and synchronous opening and closing; when the locking member 160 is closed, the door leaf 140 is in the first state, and the door leaf 140 slides left and right on the first slide rail 111 and the second slide rail 131; when the locking member 160 is opened, the door leaf 140 is in the second state, the first connecting member 151 can slide on the first screw rod 141a and the second slide rail 131 at the same time, and the second connecting member 152 can slide on the first slide rail 111 and the third slide rail 142a at the same time; at the same time, on this basis, it can rotate around the straight line formed by the first connecting member 151 and the second connecting member 152 as the axis.

[0058] Preferably, the locking component 160 provided on the first connecting member 151 and the second connecting member 152 is an electromagnetic lock. Under normal working conditions, the electromagnetic lock generates a magnetic field by powering on to attract the metal plate or the armature, thereby achieving locking and opening. That is, the locking component 160 is the key method for the state conversion of the door leaf 140. When power is on, the magnetic field exists and the door leaf 140 maintains the first state; once the power is off, the magnetic field disappears and the door leaf 140 is converted to the second state.

At this time, the second connecting member 152 is fixed at the position where the first slide rail 111 fails. The door leaf 140 can slide on the first slide rail 111 and the second slide rail 131, and the door leaf 140 can rotate with the second connecting member 152 as the axis, so that even if the bottom slide rail cannot work normally, the door leaf 140 can still be opened for maintenance or passage in an emergency.

At this time, the door leaf 140 can only move on the first slide rail 111 and the second slide rail 131, but the door leaf 140 can rotate around the first connecting member 151 and the second connecting member 152, allowing the door leaf 140 to rotate around these points, thereby maintaining a certain open state.
