Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning engineering, and particularly relates to a backboard air conditioner with a side-embedded modular electric control box. Background Art

[0002] The backboard air conditioner of the existing server cabinet in the data center 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 backboard air conditioner is 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 proportion of the area of the heat exchanger in the backboard air conditioner is controlled to reduce the weight of the backboard air conditioner, which results in low heat exchange efficiency per unit area of the backboard air conditioner. Therefore, in the prior art, in order to improve the heat exchange efficiency per unit area of the backboard air conditioner, the backboard air conditioner is slidably installed on the server cabinet through a guide rail, and the bearing capacity is improved through the guide rail, and the area of the heat exchanger in the backboard air conditioner is increased. However, with the increase of the area of the heat exchanger, the installation space of the control board is reduced. Previously, a maintenance door could be opened at the position corresponding to the control board on the outer panel to maintain the control board. With the increase of the area of the heat exchanger, the fan assembly needs to be arranged at the position corresponding to the heat exchanger on the outer panel, resulting in insufficient space to arrange the maintenance door. When the control board needs to be maintained, the entire outer panel needs to be disassembled, resulting in a large amount of maintenance work and complex maintenance of the control board. Summary of the Utility Model

[0003] The utility model provides a backboard air conditioner with a side-embedded modular electric control box for facilitating the maintenance of the control board to solve the deficiencies of the prior art.

[0004] To achieve the above object, the utility model first proposes a backboard air conditioner with a side-embedded modular electric control box, which includes a door frame, a heat exchanger assembly installed in the door frame, an outer panel installed outside the door frame to enclose the door frame, and a fan assembly installed on the outer panel, and further includes a fixed bracket and an electric control box body. The electric control box body includes a pull-out box and a pull-out panel installed on the front panel of the pull-out box. A plurality of through holes convenient for wire threading are provided on the rear panel of the pull-out box to form a wire passing hole. A control board is fixed on the bottom plate inside the pull-out box. A pull-out area matching the size of the pull-out box is provided inside the fixed bracket. A drawer opening communicating with the pull-out area is provided on one side of the fixed bracket. The pull-out box is inserted into the pull-out area of the fixed bracket through the drawer opening, and the two side plates of the pull-out box are slidably connected with the fixed bracket. The fixed bracket is installed on the left or right side of the door frame. An inspection opening for the pull-out box to enter and exit is provided at the position corresponding to the drawer opening of the fixed bracket on the left or right side of the door frame.

[0005] In this embodiment, the fixed bracket includes an upper fixing plate and a lower fixing plate. The upper fixing plate and the lower fixing plate are arranged in parallel. The upper fixing plate and the lower fixing plate are connected and fixed by a baffle. A spacing is provided between the upper fixing plate and the lower fixing plate to form the drawing area.

[0006] In this embodiment, a spring plunger is installed on one side of the upper fixing plate and / or the lower fixing plate facing the side plate of the drawer box. A positioning groove matching the spring plunger is provided on the outer side surface of the side plate of the drawer box.

[0007] In this embodiment, the side plates of the drawer box are connected to the upper and lower fixing plates through guide rails.

[0008] In this embodiment, a handle is installed on the outer side of the drawing panel.

[0009] In this embodiment, the maintenance opening matches the size of the drawing panel. The drawer box is inserted into the drawing area, and the drawing panel is clamped in the maintenance opening, so that the outer side surface of the drawing panel is flush with the outer side surface of the door frame.

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

[0011] 1. The main body of the electric control box of this device is installed on the left or right side of the back panel air conditioner, and the control board is installed inside the electric control box main body, so that the electric control box of the electric control box main body can be drawn out from the side of the back panel air conditioner. In this way, there is no need to open a maintenance door on the outer panel, and it will not interfere with the fan assembly arranged on the outer panel. Moreover, the side-drawing structure can completely pull out the control board, which is convenient for maintenance.

[0012] 2. A handle is installed on the outer side of the drawing panel, which can conveniently hold the electric control box for the drawing action.

[0013] 3. A wire passing hole is provided on the electric control box, which can facilitate the entry of control lines and the like into the electric control box.

[0014] 4. The drawer box is locked and positioned through the cooperation of the spring plunger and the positioning groove. The positioning beads on the spring plunger are clamped in the positioning groove of the drawer box, giving a pre-tightening force to the drawer box, so as to position the insertion position of the drawer box. When the drawer needs to be pulled out, with a little force, the drawer box can be pulled out from the drawing area by overcoming the elastic force of the spring plunger, ensuring the stability of the insertion of the drawer box.

[0015] In summary, this device adopts a side-embedded electric control box, which is convenient for maintaining the control board without interfering with the heat exchanger and the fan assembly. Description of the Drawings
