Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning engineering, and particularly relates to a server cabinet translation type back panel air conditioning system. Background Art

[0002] In existing data center server cabinets, back panel air conditioners are generally used as the active heat dissipation system. The back panel air conditioner includes a door frame, a heat exchanger assembly installed in the door frame, a control board, an outer panel installed outside the door frame to enclose the door frame, and a fan assembly installed on the outer panel. Since the refrigerant inlet and outlet of the heat exchanger need to be connected to the compressor through pipelines, in order to facilitate the layout of the pipelines and the maintenance of the heat exchanger assembly and the control board, the existing back panel air conditioners are generally hinged to the server cabinet. However, due to the low load-bearing limit of the hinge, in order to prevent the hinge from deforming, generally, the heat transfer efficiency per unit area of the back panel air conditioner is reduced by controlling the proportion of the heat exchanger area in the back panel air conditioner or restricting the thickness of the heat exchanger, so that it does not have a refrigeration advantage for high-load cabinets. Content of the Utility Model

[0003] The utility model solves the deficiencies of the prior art and provides a server cabinet translation type back panel air conditioning system that increases the heat transfer area of the heat exchanger on the back panel air conditioner, and the back panel air conditioner is opened by means of translation and sliding to realize the maintenance of the server.

[0004] To achieve the above object, the utility model first proposes a server cabinet translation type back panel air conditioning system, which includes a cabinet wall body. The cabinet wall body is assembled by arranging multiple groups of server cabinets side by side. Horizontally arranged upper door frames and lower door frames are respectively fixed at the top and bottom of the air inlet side or the air outlet side of the cabinet wall body. Multiple back panel air conditioner bodies matching the server cabinets are slidably installed on the cabinet wall body between the upper door frame and the lower door frame.

[0005] In this embodiment, a hanging rail is installed on the upper door frame, and a sliding rail is installed on the lower door frame. The top and bottom of the back panel air conditioner body are respectively slidably installed in the hanging rail and the sliding rail.

[0006] In this embodiment, a handle is installed on the outer side of the back panel air conditioner body. Through the handle, it is convenient to move the back panel air conditioner body on the sliding rail.

[0007] In this embodiment, on the outermost server cabinets at both ends of the cabinet wall, a pair of split doors are hinged between the upper and lower doorframes. In the initial state, multiple backplate air conditioner bodies are arranged side by side between the upper and lower doorframes, and the backplate air conditioner bodies are horizontally limited by the two side doors. In the maintenance state, the two side doors are opened to provide space for the sliding of the backplate air conditioner bodies. Since each backplate air conditioner body corresponds to a server cabinet, and doors are arranged on the outermost server cabinets at both ends of the cabinet wall, when the doors are closed, all the backplate air conditioner bodies are clamped by the two side doors, thus limiting the sliding of the backplate air conditioner bodies. When maintenance is required, opening the two side doors is equivalent to providing two sliding spaces for the sliding of the backplate air conditioner bodies. Thus, according to the server cabinet to be maintained, the backplate air conditioner body corresponding to this server cabinet can be translated to either side, so that the servers in the server cabinet are exposed, facilitating maintenance.

[0008] In this embodiment, a heat exchanger is provided inside the backplate air conditioner body. The inlet and outlet of the heat exchanger are respectively arranged at the top and bottom of the backplate air conditioner body. Guide grooves are provided inside both the upper doorframe and the lower doorframe along the sliding direction of the backplate air conditioner body. Refrigerant inlets and outlets matching the inlets and outlets of the heat exchanger are provided in the guide grooves. Refrigerant hoses are also installed in the guide grooves. The refrigerant hoses connect the inlets and outlets of the heat exchanger with the refrigerant inlets and outlets. The length of the refrigerant hose is D, the horizontal distance between the inlet and outlet of the heat exchanger and the refrigerant inlets and outlets in the same guide groove is A, and the maximum sliding distance of the backplate air conditioner body between the upper and lower doorframes is B, and D≥A + B.

[0009] In this embodiment, guide wheels are also installed on the top and bottom of the backplate air conditioner body. The guide wheels are linked with the backplate air conditioner body. The guide wheels are arranged in the guide grooves. A limiting groove matching the outer diameter of the refrigerant hose is provided on the outer circumference of the guide wheels. In the initial state, one end of the refrigerant hose is connected to the inlet and outlet of the heat exchanger, and the other end is connected to the refrigerant inlets and outlets. The middle part of the refrigerant hose is installed in the limiting groove of the guide wheel, so that the refrigerant hose is arranged in a U shape in the guide groove under the limitation of the three points of the inlet and outlet of the heat exchanger, the guide wheel, and the refrigerant inlets and outlets.

[0010] With the above structure, the device has the following advantages:

[0011] 1. The backplate air conditioner body of this device is installed on the upper doorframe and the lower doorframe by means of sliding. On the one hand, the sliding rail has better load-bearing capacity compared with the hinge, so that the proportion of the heat exchanger area in the backplate air conditioner can be increased or the thickness of the heat exchanger can be increased, achieving the purpose of increasing the heat exchange area and the heat exchange efficiency per unit area. On the other hand, through the sliding rail, the backplate air conditioner body can be slid and translated during maintenance, facilitating the maintenance of the servers.

[0012] 2. A suspension rail is installed on the upper door frame of this device, and a sliding rail is installed on the lower door frame. Through the combined action of the suspension rail and the sliding rail, the large-weight backplate air conditioner body can be better supported to ensure smooth sliding.

[0013] 3. The inlet and outlet of the heat exchanger in the backplate air conditioner body of this device are connected to the refrigerant inlet and outlet on the server cabinet through refrigerant hoses, thereby connecting the heat exchanger to the compressor. In order to prevent the refrigerant hoses from being bent and blocked when the backplate air conditioner body moves horizontally, a guide wheel is provided on the backplate air conditioner body, so that the refrigerant hoses are arranged in a U shape in the guide groove under the limitation of the three points of the inlet and outlet of the heat exchanger, the guide wheel, and the refrigerant inlet and outlet. The function of the guide wheel is similar to that of the movable pulley in the pulley mechanism. When the backplate air conditioner body moves, the refrigerant hoses are always in the limit groove of the guide wheel and move under the guiding action of the guide wheel, ensuring the stable movement of the refrigerant hoses in the guide groove, preventing the refrigerant hoses from being bent and blocked when the backplate air conditioner body moves horizontally, and improving the service life of the refrigerant hoses.

[0014] In summary, the backplate air conditioner body of this device is connected to the upper and lower door frames through sliding rails, which improves the load rate of the backplate air conditioner body, thereby increasing the heat exchange area of the heat exchanger in the backplate air conditioner body and improving the heat exchange efficiency per unit area. At the same time, through the sliding method, it is also convenient for server maintenance. Description of the Drawings

[0023] As Figures 1 to 4 shown, a server cabinet translational backplane air conditioning system includes a cabinet wall 1, which is assembled by arranging multiple groups of server cabinets side by side. Horizontally and oppositely arranged upper door frames 11 and lower door frames 13 are respectively fixed at the top and bottom of the air inlet side or the air outlet side of the cabinet wall 1. Multiple backplane air conditioning bodies 2 matching the server cabinets are slidably installed on the cabinet wall 1 between the upper door frame 11 and the lower door frame 13. Specifically, a hanging rail 15 is installed on the upper door frame 11, a sliding rail 16 is installed on the lower door frame 13, and the top and bottom of the backplane air conditioning body 2 are respectively slidably installed in the hanging rail 15 and the sliding rail 16. A handle 21 is installed on the outer side of the backplane air conditioning body 2, and through the handle 21, it is convenient to move the backplane air conditioning body 2 on the sliding rail 16.

[0024] Further, on the outermost server cabinets at both ends of the cabinet wall 1, double-opening cabinet doors 12 are hinged between the upper and lower door frames 13. In the initial state, multiple backplane air conditioning bodies 2 are arranged side by side between the upper and lower door frames 13, and the backplane air conditioning bodies 2 are limited in the horizontal direction by the two-side cabinet doors 12. During the maintenance state, the two-side cabinet doors 12 are opened to provide space for the sliding of the backplane air conditioning bodies 2. Since each backplane air conditioning body 2 corresponds to a server cabinet, and the cabinet doors 12 are arranged on the outermost server cabinets at both ends of the cabinet wall 1, when the cabinet doors 12 are closed, all the backplane air conditioning bodies 2 are clamped by the two-side cabinet doors 12, thereby limiting the sliding of the backplane air conditioning bodies 2. When maintenance is required, the two-side cabinet doors 12 are opened, which is equivalent to providing two sliding spaces for the sliding of the backplane air conditioning bodies 2. Thus, according to the server cabinet to be maintained, the backplane air conditioning body 2 corresponding to this server cabinet can be translated to either side to expose the servers in the server cabinet, thereby facilitating maintenance.

[0025] As Figure 2 、 3As shown in FIGS. 4 and 5, a heat exchanger is provided inside the backboard air conditioner body 2. The inlet and outlet of the heat exchanger are respectively arranged at the top and bottom of the backboard air conditioner body 2. Guide grooves 14 are provided inside both the upper door frame 11 and the lower door frame 13 along the sliding direction of the backboard air conditioner body 2. Refrigerant inlets and outlets that match the inlets and outlets of the heat exchanger are provided inside the guide grooves 14. A refrigerant hose 3 is also installed inside the guide grooves 14. The refrigerant hose 3 connects the inlets and outlets of the heat exchanger with the refrigerant inlets and outlets. The length of the refrigerant hose 3 is D, the horizontal distance between the inlets and outlets of the heat exchanger and the refrigerant inlets and outlets inside the same guide groove 14 is A, and the maximum distance for the backboard air conditioner body 2 to slide between the upper and lower door frames 13 is B, and D≥A + B. Further, guide wheels 4 are installed on both the top and bottom of the backboard air conditioner body 2. The guide wheels 4 are installed on the backboard air conditioner body 2 through vertically arranged rotating shafts to achieve the linkage between the guide wheels 4 and the backboard air conditioner body 2. The guide wheels 4 are arranged inside the guide grooves 14. A limiting groove that matches the outer diameter of the refrigerant hose 3 is provided on the outer circumference of the guide wheels 4. In the initial state, one end of the refrigerant hose 3 is connected to the inlets and outlets of the heat exchanger, and the other end is connected to the refrigerant inlets and outlets. The middle part of the refrigerant hose 3 is installed in the limiting groove of the guide wheels 4, so that the refrigerant hose 3 is arranged in a U shape inside the guide groove 14 under the limitation of the inlets and outlets of the heat exchanger, the guide wheels 4, and the refrigerant inlets and outlets. The role of the guide wheels 14 is similar to that of the movable pulley in a pulley mechanism. When the backboard air conditioner body moves, the refrigerant hose is always inside the limiting groove of the guide wheels and moves under the guiding action of the guide wheels, ensuring the stability of the refrigerant hose when moving inside the guide groove, preventing the refrigerant hose from being bent and blocked when the backboard air conditioner body translates, and improving the service life of the refrigerant hose.
