Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a cabinet and a cabinet air conditioner. Background Art

[0002] In recent years, with the construction of 5G base stations, the number of macro and micro stations has increased significantly. The internal switches and power conversion equipment of macro and base stations are much more than those of 4G base stations and macro stations, and the heat consumption is also very huge. These base stations and macro stations are generally built on the side of the road or next to residential buildings, so the area they can occupy is limited, so macro and base stations have high requirements for space. At the same time, because 5G base stations and macro stations have huge heat dissipation, the cooling equipment is required to generate as much cooling as possible, the smaller the volume, and the smaller the space occupied.

[0003] When installing, debugging and repairing cabinet air conditioners, workers often need to open the front panel for operation. If the front panel is an integral panel, the operator needs to remove the panel; or the cabinet can be connected by hinges on the side frame, then the cabinet surface can be opened to the left or right.

[0027] See also Figures 1 to 7 As shown, according to an embodiment of the present application, the cabinet includes a casing 1, a first front door panel 2 and a second front door panel 3, the first front door panel 2 and the second front door panel 3 are both installed on the casing 1, the first front door panel 2 is arranged on the upper side of the second front door panel 3 and is hinged to the second front door panel 3, a guide ring 4 is provided on the side of the first front door panel 2 facing the inside of the casing 1, and the up, down, left and right positions of the first front door panel 2 relative to the second front door panel 3 can be adjusted.

[0028] The cabinet has modified the structure of the front door panel, dividing the front door panel into a first front door panel 2 and a second front door panel 3, and fixing the guide ring 4 on the first front door panel 2, so that the first front door panel 2 can rotate relative to the second front door panel 3, and can move up, down, left and right relative to the second front door panel 3. Therefore, it can not only reduce the installation difficulty when installing the air conditioner, making assembly and disassembly more convenient, but also reduce the space occupied by the door panel during assembly and disassembly. When matching the guide ring 4 and the fan, the position of the guide ring 4 can be adjusted by moving the up, down, left and right positions of the first front door panel 2, so that a good matching relationship is formed between the guide ring 4 and the fan, thereby effectively solving the problem of fan jamming or uneven air intake caused by the jamming of the guide ring 4 and the fan or the large gap.

[0029] In one embodiment, a first hinge plate 5 is provided on the first front door panel 2, and a second hinge plate 6 is provided on the second front door panel 3, and the first hinge plate 5 is hinged to the second hinge plate 6. In this embodiment, the first front door panel 2 and the second front door panel 3 are connected by a hinge, and the hinge includes the first hinge plate 5 and the second hinge plate 6, and a hinge shaft connected between the first hinge plate 5 and the second hinge plate 6, so that the hinge and the first front door panel 2 and the second front door panel 3 form a mutually independent detachable structure, which can facilitate the replacement and maintenance of the first front door panel 2 and the hinge, and can reduce the replacement and maintenance costs.

[0030] In one embodiment, the first hinge plate 5 is provided with a waist-shaped hole 7 extending in the horizontal direction, and the second hinge plate 6 is provided with a waist-shaped hole 7 extending in the vertical direction. The first front door panel 2 is fixedly connected to the first hinge plate 5 by bolts passing through the waist-shaped hole 7, and the second front door panel 3 is fixedly connected to the second hinge plate 6 by bolts passing through the waist-shaped hole 7. In this embodiment, by respectively providing waist-shaped holes 7 with different extending directions on the first hinge plate 5 and the second hinge plate 6, when installing and debugging, the first hinge plate 5 can firstly adjust the up-down position relative to the second front door panel 3 through the second hinge plate 6, and after the up-down position is properly adjusted, the second hinge plate 6 is fixed to the second front door panel 3, and then the left-right position of the first front door panel 2 relative to the first hinge plate 5 is adjusted, so that the position of the guide ring 4 located on the first front door panel 2 can match the position of the fan in both the up-down and left-right directions, and ensure that the gap formed between the guide ring 4 and the fan is uniform. In the present embodiment, after the first front door panel 2 is fixedly connected to the second front door panel 3 at the bottom, the assembly accuracy of the first front door panel 2 can still be fine-tuned through the action of the hinge to prevent problems such as jamming due to insufficient clearance or uneven air intake due to excessive clearance caused by processing errors or installation errors when assembling the guide ring 4 and the fan fixed on the first front door panel 2.

[0031] In one embodiment, a waist-shaped hole 7 extending in the vertical direction is provided on the first hinge plate 5, and a waist-shaped hole 7 extending in the horizontal direction is provided on the second hinge plate 6. The first front door panel 2 is fixedly connected to the first hinge plate 5 by bolts passing through the waist-shaped hole 7, and the second front door panel 3 is fixedly connected to the second hinge plate 6 by bolts passing through the waist-shaped hole 7. In this embodiment, the installation process of the first hinge plate 5 is basically the same as that of the previous embodiment, except that the order of installation and adjustment is different. In this embodiment, the left and right position of the second hinge plate 6 on the second front door panel 3 is first adjusted, and then the up and down position of the first front door panel 2 on the first hinge plate 5 is adjusted to achieve the purpose of adjusting the position of the guide ring 4 to the right position.

[0032] In one embodiment, when the first front door panel 2 is flipped to open the housing 1, the back side of the first front door panel 2 can fit the support surface of the second front door panel 3, so as to ensure that after the first front door panel 2 is opened, it can be fully folded on the second front door panel 3, and the support is formed by the second front door panel 3, without adding an additional support structure. When the unit is repaired or the program is updated, by folding the first front door panel 2 on the second front door panel 3, the occupied space after the first front door panel 2 is opened can be minimized, which will not affect the operation and position of the operator. At the same time, since the first front door panel 2 and the second front door panel 3 are hinged, it is not necessary to completely remove the first front door panel 2 from the second front door panel 3, thus solving the problem that the entire panel needs to be disassembled during traditional maintenance or the side of the panel is opened during installation, which affects the left and right movement space of the operator and is prone to collision and scratches.

[0033] In this embodiment, the second front door panel 3 is fixed on the casing 1, and the first front door panel 2 can rotate 180° around the hinge relative to the second front door panel 3 to ensure that the first front door panel 2 and the second front door panel 3 can fully fit together to avoid obstruction to the operator.

[0034] In one embodiment, a sealing strip 8 is provided between the first front door panel 2 and the second front door panel 3. When the first front door panel 2 closes the housing 1, the first front door panel 2 and the second front door panel 3 are sealed by the sealing strip 8. There is a rotation gap between the first front door panel 2 and the second front door panel 3. This rotation gap can be formed by pasting a sealing strip or other sealable structural devices on the outer side or the inner side of the door panel. The sealing between the upper side and the lower side of the door panel is mainly to prevent water, dust, mosquitoes and other factors that may cause unit failures.

[0035] In the given embodiment, when the first front door panel 2 closes the housing 1, the first front door panel 2 and the housing 1 are snap-fitted, screwed or magnetized. The first front door panel 2 and the housing 1 are fixed and sealed by means of screws, bolts, snaps or magnet attraction. When disassembly for maintenance or program update is required, the upper side of the first front door panel 2 can be opened with a little force without taking up space. The traditional opening method is to disassemble the entire door panel or connect it with a hinge on the side. This method of disassembling the entire door panel or opening it from the side is more complicated and difficult to install and maintain. When connected by screws or bolts, frequent disassembly and assembly can easily cause problems such as screw or bolt thread slippage and poor sealing.

[0036] In this embodiment, except for the connection between the first front door panel 2 and the second front door panel 3, the other three places around the first front door panel 2, namely the upper side, left side and right side of the first front door panel 2, are installed with buckles, and the first front door panel 2 is connected and sealed with the casing 1 through the buckles; or permanent magnets or components that can generate magnetic effects when energized are installed on the upper side, left side and right side of the first front door panel 2, so that the first front door panel 2 and the casing 1 are fixed and sealed by magnetic attraction.

[0037] According to an embodiment of the present application, the cabinet air conditioner includes a cabinet, which is the cabinet mentioned above.

[0038] In one embodiment, a fan 9 is further disposed in the housing 1, and the fan 9 is disposed at a position of the housing corresponding to the first front door plate 2, and is gap-matched with the guide ring 4. The fan 9 is, for example, a centrifugal fan.

[0039] In one embodiment, a display 10 is further disposed in the housing 1 . The display 10 is disposed at a housing position corresponding to the first front door panel 2 . A display window 11 is disposed on the first front door panel 2 . The display 10 and the display window 11 correspond in position.

[0040] In one embodiment, a partition 12 is provided in the casing 1, and the partition 12 divides the casing 1 into an evaporation area and a condensation area. The evaporation area is located on the side of the partition 12 close to the first front door panel 2. A fan 9, an electrical box 14, a display 10 and an evaporator 13 are provided in the evaporation area, and a condenser 15 and a compressor 16 are provided in the condensation area.

[0041] In this embodiment, the evaporator 13 is arranged at the lower part of the casing 1 corresponding to the second front door panel 3, and the fan 9, the electrical box 14, and the display 10 are arranged at the upper part of the casing 1 corresponding to the first front door panel 2. The second front door panel 3 is the lower structure of the front door panel, and the second front door panel 3 is fixed to the casing 1 using screws, bolts or rivets. Because the structure on the inner side of the second front door panel 3 is the evaporator 13, the evaporator 13 is not easy to be damaged and does not need to be repaired, so it does not need to be disassembled frequently. The first front door panel 2 is the upper structure of the front door panel, and the inner side of the first front door panel 2 is the display 10, the fan 9, and the electrical box 14. There are various electronic components inside the electrical box 14. Since the electronic components inside the display 10, the fan 9, and the electrical box 14 are prone to failure, when a failure occurs, or when the program of the unit needs to be refreshed, the door panel needs to be disassembled for maintenance and updating. Therefore, by arranging the display 10, fan 9, and electrical box 14 at the position corresponding to the first front door panel 2, the easy assembly and disassembly feature of the first front door panel 2 can be utilized to reduce the difficulty of replacing and repairing the display 10, fan 9, and electrical box 14.

[0042] When the unit needs maintenance or program update, the first front door panel 2 can be opened and rotated 180° around the rotation axis. In this embodiment, the rotation axis is a hinge. After the first front door panel 2 is opened, the fan 9, electrical box 14 and display 10 inside the unit can be seen. The fan 9, electrical box 14 and display 10 are fixed inside the casing 1 and have no connection with the first front door panel 2, which does not affect the opening of the first front door panel 2.

[0043] The first front door panel 2 can rotate 180° around the hinge. After the rotation, the fan 9, the electrical box 14 or the display 10 can be directly inspected, repaired or updated. The operation is simple and there is no need to disassemble the entire front door panel, which solves the problem of collision or scratches on workers caused by opening the door panel on the side of the cabinet air conditioner. The guide ring 4 is fixed on the first front door panel 2, and the first front door panel 2 can move horizontally and vertically to adjust the assembly gap between the guide ring 4 and the fan 9, which solves the problem of jamming caused by insufficient gap or uneven air intake caused by excessive gap.

[0044] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0045] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
