1 to 12, a sliding door opening / closing structure (hereinafter referred to as a "door opening / closing structure") of a coupon system for cooling a data center server according to a preferred embodiment of the present invention includes a data center server cooling housing system (10).

The door opening and closing structure includes a door frame 20, a door 30, a restoring module 40, a first pulley 50, a second pulley 60, a pneumatic spring device 70, And a stopper device 110.

The door frame 20 is a frame provided with a door 30 to be described later. The door frame 20 is disposed on the upper and side portions of a door 30 described later. The door frame 20 may be made of metal. The upper portion of the door frame 20 is preferably provided with a rail-like structure through which the first pulley 50 or the second pulley 60, which will be described later, can move.

The door 30 is slidably installed on the door frame 20. One or a pair of the doors 30 may be provided. In the present embodiment, the doors 30 are provided in pairs. A wheel 31 may be installed on the lower surface of the door 30 to reduce friction with the ground. The pair of doors 30 are closed in contact with each other. More specifically, a protruding engaging portion 32 is provided on one side of one of the pair of doors 30. The other one of the pair of doors 30 is provided with a receiving groove 34 for receiving the projecting engaging portion 32. And the protruding engaging portion 32 and the receiving recess 34 are coupled to each other in a state where the pair of doors 30 are closed. The projecting engagement portion 32 and the accommodation groove portion 34 improve the sealing performance in a state where the pair of doors 30 are closed. The protruding engaging portion 32 and the receiving groove 34 are preferably formed in a tapered shape in cross section. If the end surfaces of the protruding engaging portion 32 and the receiving recess 34 are formed in a tapered shape, they are smoothly and naturally coupled when they are coupled with each other.

The restoration module (40) is fixed to the door frame (20). The restoration module (40) includes a drum (44) and a cable (46).

The drum 44 is rotatably mounted on the door frame 20. The drum 44 has an elastic restoring force in a constant rotation direction by a spring (not shown). A tension adjusting device capable of adjusting the magnitude of the initial elastic restoring force of the drum 44 may be provided. The tension adjusting device may be configured to adjust the degree of the initial winding state of the spring winding spring by applying a one-way clutch.

One end of the cable 46 is connected to the first pulley 50, which will be described later, and the other end is fixed to the drum 44. The cable (46) is wound on the outer peripheral surface of the drum (44).

The first pulley 50 is fixed to the door 30. In the present embodiment, the first pulley 50 is fixed to the upper surface of the door 30. The first pulley 50 includes a rotating roller 52. The rotary roller 52 may be rotated along the rail shape provided on the door frame 20. One end of the cable 46 is connected to the first pulley 50. Accordingly, the first pulley 50 moves together with the door 30 during the opening or closing of the door 30. [

The second pulley 60 is fixed to the door 30. The second pulley 60 is fixed in a manner similar to the first pulley 50. The second pulley 60 includes a rotating roller 64 in the same manner as the first pulley 50. The second pulley 60 has a protruding locking part 62 protruding upward. The protruding locking portion 62 may be temporarily connected to or separated from the pneumatic spring device 70 described later in the process of opening or closing the door 30. More specifically, the protruding locking portion 62 is coupled to the pneumatic spring device 70 in a state in which the door 30 is completely closed. On the other hand, the door 30 is separated from the pneumatic spring device 70 in a completely opened state. The second pulley 60 is disposed on the opposite side of the restoration module 40 with the first pulley 50 interposed therebetween.

The pneumatic spring device (70) is fixed to the door frame (20). The pneumatic spring device 70 is installed at a position corresponding to the second pulley 60 in a state where the door 30 is completely closed. The pneumatic spring device 70 includes a body 72, a tube 74, a rod 75, a movement guide 80, and a separation rail 90.

The body 72 has a downwardly opened structure and is elongated in a direction in which the door 30 moves. The body 72 is divided into a portion that can be moved when the rod 75 is expanded and a portion where the tube 74 is fixed. The body 72 has a rail-shaped structure for guiding the linear motion of the movement guide 80 moving together with the rod 75.

The tube 74 is a hollow pipe-like structure. The tube 74 may be of a structure adopted to a known pneumatic cylinder or an air spring.

The rod 75 is coupled to the inside of the tube 74 and is installed to be movable with respect to the tube 74 via a piston (not shown). The rod 75 is spring-operated by the pneumatic pressure acting on the piston. The tip of the rod 75 has a T-shaped fixing portion 76. It is preferable that the T-shaped fixing part 76 is formed thicker than the thickness of the rod 75.

The movement guide (80) is coupled to the distal end of the rod (75). The movement guide 80 is engaged with the front and rear surfaces of the projecting portion 62. More specifically, the movement guide 80 has protruding portions which are respectively supported on the front surface and the rear surface of the protruding locking portion 62.

Further, the movement guide 80 has a fixing groove portion 82 coupled to the T-shaped fixing portion 76. The fixing groove portion 82 is provided to facilitate the operation when the movement guide 80 and the rod 75 are engaged or separated.

The separating rail 90 is fixed to one end of the body 72. The separation rail 90 is a member that acts to change the height of the movement guide 80 in a state where the rod 75 is extended to the maximum extent. That is, the separating rail 90 moves the movement guide 80 upward so as to be separated from the protruding engaging portion 62 when the movement guide 80 reaches one end of the body 72. The separating rail 90 has a curved rail 92 formed in a curved shape. The curved rail part 92 smoothly changes the direction of the upward movement of the moving guide 80 out of the body 72 so that the protruding locking part 62 can be smoothly separated from the pneumatic spring device 70 .

The pneumatic spring device (70) includes a restoring spring (100). The restoring spring 100 may be a coil spring. One end of the restoring spring 100 is fixed to the movement guide 80. The other end of the restoring spring 100 is fixed to the other end of the body 72. The restoring spring 100 exerts an elastic restoring force in a direction in which the rod 75 is compressed. The restoring spring 100 may be a compression coil spring. The restoring spring 100 urges the movement guide 80 from the separating rail 90 to the body 72 at a moment when the protrusion engaging portion 62 is separated from the movement guide 80 and then is re- Contributing to the movement. In addition, the restoring spring 100 may be configured such that the door 30 is smoothly closed without being subjected to a reaction shock due to the sudden buffering of the pneumatic spring device 70 in the process of closing the pair of doors 30 . The resilient restoring force of the restoring spring 100 may be greater than the resilient restoring force of the spring spring of the restoring module 40. That is, the restoring spring 100 exerts a dominant elastic restoring force in a section in which the pneumatic spring device 70 operates.

The stopper device 110 is fixed to the door frame 20. The stopper device 110 elastically fixes the second pulley 60 in a state where the door 30 is fully opened. The stopper device 110 includes a locking member 112 and a locking and unlocking member 114. The locking member 112 is a cantilevered structure. The free end portion of the lock member 112 elastically encloses the upper portion of the rotating roller 64 of the second pulley 60 to prevent rotation thereof. The locking member 112 serves to fix the door 30 so that the door 30 is not automatically closed when the door 30 is fully opened.

The lock releasing member 114 is installed to be in contact with the side surface of the rotating roller 64 of the second pulley 60. The lock releasing member 114 has an elastic restoring force for moving the door in a closing direction. The lock releasing member 114 may be made of a material having good elasticity such as rubber. The lock releasing member 114 applies an additional force to the door 30 in the direction in which the door 30 is opened by the person while the door 30 is locked by the lock member 112 , The lock releasing member (114) is momentarily compressively deformed and then elastically restored, and the second pulley (60) is released from the lock member (112).

Hereinafter, the operation and effect of the door opening / closing structure including the above-described structure will be described in detail as an example of a process of opening the door 30 and a process of closing the door 30. [

First, the process of opening the door 30 will be described.

The description starts from a state in which the pair of doors 30 are completely closed as shown in Fig. A person exerts a force in a direction in which the pair of doors 30 are moved away from each other. The pair of doors 30 open the cable 46 while releasing the cable 44 from the drum 44 while overcoming the elastic restoring force of the restoration module 40. Also, in this process, the first pulley 50 moves while unscrewing the cable 46 connected to the restoration module 40. The second pulley 60 moves while extending the rod 75 of the pneumatic spring device 70. In this process, the projecting engaging portion 32 of the second pulley 60 acts as an initial driving force for extending the rod 75 through the movement guide 80. When the initial driving force is applied by the external force, the rod 75 overcomes the elastic restoring force of the restoring spring 100 due to the normal action of the air spring. In this process, the restoring spring 100 is stretched so that the rod 75 is not abruptly stretched, thereby exerting an elastic restoring force.

As the door 30 is opened, the rod 75 is extended. As a result, the movement guide 80 moves out of the body 72 in a state where the rod 75 is extended to the maximum extent. The movement guide 80 moves out of the body 72 and enters the separating rail 90. The separation rail 90 moves the movement guide 80 upward. Accordingly, the movement guide 80 and the protruding engaging portion 62 are separated from each other. The second pulley 60 is separated from the pneumatic spring device 70 as the door 30 moves in a direction to keep it open. When the door 30 reaches the maximum open position, the rotation roller 64 of the second pulley 60 elastically contacts the lock member 112 of the stopper device 110 . Accordingly, the door 30 is maintained at the maximum open state. If the door 30 is kept open, the operator can bring the necessary items into or out of the system 10 securely.

Now, the process of closing the door will be described.

The description starts from the state in which the door 30 is opened to the maximum as described above.

A person applies an external force in a direction in which the door 30 is opened. In this case, the lock releasing member 114 supported on the side surface of the second pulley 60 is compressed. When the external force is removed, the lock releasing member 114 is restored to its original shape by the elastic restoring force. In this process, the second pulley 60 is disengaged from the lock member 112 by the resilient restoring force of the lock releasing member 114. The door 30 is moved in the closing direction by an elastic restoring force of the spring spring of the restoration module 40.

When the second pulley 60 reaches the pneumatic spring device 70, the protruding locking portion 62 engages with the movement guide 80. The movement guide 80 moves from the separation rail 90 to the body 72. As the movement guide 80 moves along the body 72, the rod 75 contracts. As the rod 75 contracts, the pneumatic spring device 70 exerts a force opposite to the direction in which the door 30 is closed. Accordingly, the door 30 is subjected to a resistance to be closed. In this process, the door 30 receives a sudden resistance. At this time, the restoring spring 100 exerts an elastic restoring force in a direction in which the door 30 is closed. The resilient restoring force of the restoring spring 100 and the resilient restoring force of the pneumatic spring device 70 are opposite to each other. However, since the sum of the resilient restoring force of the restoring spring 100 and the resilient restoring force of the restoring module 40 is greater than the elastic restoring force of the pneumatic spring device 70, the door 30 is moved in a direction to keep it closed. In addition, a smooth closing operation is caused by significantly reducing the resistance of the door 30 to the abrupt resistance by the pneumatic spring device 70. When the rod 75 reaches the maximum retracted position, the door 30 is closed. In this state, the projecting engaging portion 32 and the receiving groove 34 of the door 30 are coupled with each other, so that the air flowing between the inside and the outside of the door 30 can be sealed well.

On the other hand, a case in which the door 30 is opened only to the maximum without opening the door 30 will be described.

The description starts from a state in which the pair of doors 30 are completely closed as shown in Fig. A person exerts a force in a direction in which the pair of doors 30 are moved away from each other. The pair of doors 30 open the cable 46 while releasing the cable 44 from the drum 44 while overcoming the elastic restoring force of the restoration module 40. Also, in this process, the first pulley 50 moves while unscrewing the cable 46 connected to the restoration module 40. The second pulley 60 moves while extending the rod 75 of the pneumatic spring device 70. In this process, the projecting engaging portion 32 of the second pulley 60 acts as an initial driving force for extending the rod 75 through the movement guide 80. When the initial driving force is applied by the external force, the rod 75 overcomes the elastic restoring force of the restoring spring 100 due to the normal action of the air spring. In this process, the restoring spring 100 is stretched so that the rod 75 is not abruptly stretched, thereby exerting an elastic restoring force.

As the door 30 is opened, the rod 75 is extended. As a result, the movement guide 80 moves out of the body 72 in a state where the rod 75 is extended to the maximum extent. The movement guide 80 moves out of the body 72 and enters the separating rail 90. The separation rail 90 moves the movement guide 80 upward. Accordingly, the movement guide 80 and the protruding engaging portion 62 are separated from each other. The second pulley 60 is separated from the pneumatic spring device 70 as the door 30 moves in a direction to keep it open. In this state, the person removes the external force acting on the door 30. [ In this case, the door 30 is moved in the closing direction by the elastic restoring force of the restoration module 40.

When the second pulley 60 reaches the pneumatic spring device 70, the protruding locking portion 62 engages with the movement guide 80. The movement guide 80 moves from the separation rail 90 to the body 72. As the movement guide 80 moves along the body 72, the rod 75 contracts. As the rod 75 contracts, the pneumatic spring device 70 exerts a force opposite to the direction in which the door 30 is closed. Accordingly, the door 30 is subjected to a resistance to be closed. In this process, the door 30 receives a sudden resistance. At this time, the restoring spring 100 exerts an elastic restoring force in a direction in which the door 30 is closed. The resilient restoring force of the restoring spring 100 and the resilient restoring force of the pneumatic spring device 70 are opposite to each other. However, since the sum of the resilient restoring force of the restoring spring 100 and the resilient restoring force of the restoring module 40 is greater than the elastic restoring force of the pneumatic spring device 70, the door 30 is moved in a direction to keep it closed. In addition, a smooth closing operation is caused by significantly reducing the resistance of the door 30 to the abrupt resistance by the pneumatic spring device 70. When the rod 75 reaches the maximum retracted position, the door 30 is closed. In this state, the projecting engaging portion 32 and the receiving groove 34 of the door 30 are coupled with each other, so that the air flowing between the inside and the outside of the door 30 can be sealed well.

As described above, the sliding door opening / closing structure of the data center server cooling system according to the present invention can open the door manually, maintain the opened state at the maximum opened state, The door is automatically closed when the external force applied to the door is removed, so that the door of the container system can be positioned variously if necessary. Basically, There are advantages.

In other words, the sliding door opening / closing structure of the data center server cooling system according to the present invention has a structure in which the second pulley is engaged with or separated from the pneumatic spring device, so that smooth and rebound shock is not generated in the process of closing the door to provide. In addition, when the restoring spring is provided as in the preferred embodiment of the present invention, the restoring module and the restoring spring cooperate in the process of closing the door, thereby providing a more gentle closing of the door. Further, in the case where the stopper device is provided as in the preferred embodiment of the present invention, the door can be kept maximally opened, and the door can be easily closed by applying additional pressure.

While the present invention has been described with reference to the preferred embodiments, it is to be understood that the invention is not to be limited by the example, and various changes and modifications may be made without departing from the spirit and scope of the invention.
