[0002] As a common structure in the power system, cabinets such as distribution cabinets and control cabinets are the key to maintaining the normal operation of the power system. Therefore, it is crucial to ensure the normal operation of the above cabinets. Since a large number of electrical components are usually installed in existing distribution cabinets, control cabinets and other cabinets, and there are a large number of electrical components. Terminals and other structures are directly exposed in the cabinet, it is necessary to ensure that the temperature and humidity in the cabinet meet the set requirements.

[0003] At present, the existing temperature and humidity control devices on the market, such as the intelligent temperature and humidity controller disclosed in patent CN102622016A, have a shell and a control panel arranged on one side of the shell, a heat dissipation device is arranged above the shell, and an LED display, an LED alarm indicator, and a button for setting temperature and humidity information are arranged on the control panel. The LED display, the LED alarm indicator, and the button are respectively connected to the circuit inside the shell. Through the LED display, the LED alarm indicator, and the button for setting temperature and humidity information, the LED display can realize the intuitive display of the value through the LED display, and the control adjustment can be realized by using the button, and the alarm indication function can be provided when a fault occurs, and the heat dissipation device can be arranged to dissipate the heat inside the shell. Although the above-mentioned temperature and humidity control device with digital display can meet the temperature and humidity control and display requirements, and can realize digital and adjustable temperature and humidity control, the existing temperature and humidity control device with digital display and adjustable is divided into two types: an independently arranged structure and a structure embedded in the corresponding cabinet. For the convenience of installation and use, the industry usually embeds the temperature and humidity control device with digital display and adjustable in the cabinet to form an integral structure. At this time, the temperature and humidity control device with digital display and adjustable temperature and humidity will generate a lot of heat when used, and because the temperature and humidity control device with digital display and adjustable temperature and humidity is embedded in the cabinet, the heat generated by the temperature and humidity control device with digital display and adjustable temperature and humidity can only be dissipated in the cabinet. In addition, because the electrical components in the cabinet also generate a lot of heat during operation, the temperature in the cabinet itself is relatively high, which will inhibit the heat dissipation of the temperature and humidity control device with digital display and affect its service life.

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 2 The technical solution provided by the utility model is described in detail, but the following content is not intended to limit the utility model.

[0026] Figure 1 It is a structural diagram of an embodiment of a digital display adjustable temperature and humidity control device of the utility model; Figure 2 This is a cross-sectional view of the housing, display and control panel, and active heat dissipation duct after installation in a preferred embodiment of the utility model. Figure 1 and Figure 2 As shown, the digital display adjustable temperature and humidity control device provided in this embodiment includes: a housing 1, a display and control panel 2, a control circuit board 3 and an active heat dissipation duct.

[0027] Specifically, the housing 1 is box-shaped, and in this case, the housing 1 has an installation cavity 11, which provides a sufficiently large installation space to protect the structure installed therein. In addition, a front opening connected to the installation cavity 11 is also opened on one side of the housing 1, which provides conditions for subsequently rotating the display and control panel 2 in the housing 1 with one side exposed outside the housing 1.

[0028] Specifically, the display and control panel 2 is arranged in the front opening of the housing 1, which can not only hide most of the structure of the display and control panel 2, but also enable one side of the display and control panel 2 to be located outside the housing 1, which is convenient for operators to observe and control and adjust. In addition, a display 21 and a plurality of control keys 22 are also arranged on the display and control panel 2. During installation, the side of the display and control panel 2 with the display 21 and the control keys 22 is exposed outside the housing 1, and numerical display is realized through the display 21 to meet the digital display requirements. At the same time, control and adjustment are realized through the control keys 22, and the structural design is more reasonable.

[0029] Specifically, the control circuit board 3 is arranged in the installation cavity 11. At this time, the control circuit board 3 is electrically connected to the display 21 and the control key 22, that is, the control structure of various functions of the digital display adjustable temperature and humidity control device is realized through the control circuit board 3 to meet the use requirements of vertical and control adjustment.

[0030] Specifically, the active heat dissipation duct includes a partition 41 and a fan 42. At this time, the active heat dissipation duct is installed in the housing 1, and can mainly dissipate the heat generated in the installation cavity 11 without being affected by the temperature in the corresponding cabinet. At this time, the partition 41 is placed horizontally in the installation cavity 11 in the vertical direction, that is, the installation cavity 11 is divided into two relatively independent chambers, the upper part and the lower part, by the partition 41, forming an upper and lower air duct. At this time, a through vent 411 is also opened on the partition 41, so that the upper and lower air ducts can be connected through the vent 411, and the flowing air can pass through the through hole, and the control circuit board 3 is installed at the vent 411, so that when the flowing air passes through the through hole, the heat emitted by the control circuit board 3, which is most likely to generate heat, can be quickly taken away to meet the heat dissipation requirements. At the same time, an exhaust port 23 and an air inlet 24 are respectively provided at the upper and lower parts of the display and control panel 2, so that the exhaust port 23 and the air inlet 24 are both located on the side exposed outside the housing 1, providing conditions for subsequent direct communication with the outside, thereby avoiding the influence of the temperature inside the cabinet. In addition, the fan 42 is installed in the installation cavity 11 and located at the exhaust port 23. At this time, the fan 42 is electrically connected to the control circuit board 3, that is, when the fan 42 is in operation, the fan 42 can promote the flow of air in the air duct to achieve active heat dissipation, and directly discharge the heat to the outside through the exhaust port 23, so as to achieve the main heat dissipation and not be affected by the temperature inside the cabinet. It is worth pointing out that a number of pads are provided on the inner wall of the installation cavity 11. When the partition 41 is installed, the edge of the partition 41 is fixedly installed on the pad by screws, so as to achieve the stable installation of the partition 41 in the installation cavity 11.

[0031] More specifically, a cover plate 5 is provided in the exhaust port 23. At this time, the top of the cover plate 5 is hinged to the top edge of the exhaust port 23, so that the cover plate 5 can be flipped in the exhaust port 23. Preferably, the cover plate 5 is located on the side of the exhaust port 23 connected to the outside world, so that when exhaust is subsequently exhausted through the exhaust port 23, the airflow can push the cover plate 5 toward the outside world to achieve heat dissipation and avoid the influence of the edge of the exhaust port 23 on the flipping of the cover plate 5. When shutting down, the cover plate 5 can automatically reset under the action of gravity and cover the exhaust port 23, thereby preventing foreign matter from entering the installation cavity 11 from the exhaust port 23, and the structural design is more reasonable.

[0032] More specifically, the exhaust port 23 is arranged in a long strip structure, so that the exhaust port 23 is strip-shaped. At the same time, the length direction of the exhaust port 23 is consistent with the width direction of the display and control panel 2 after installation, so that the space occupied by the height direction of the exhaust port 23 is smaller, thereby adapting to the space of the rectangular display 21 that has been installed on the display and control panel 2, with better overall integration, more reasonable space utilization, and higher aesthetics.

[0033] More specifically, an air guide hood 43 is arranged in the installation cavity 11 and at the exhaust port 23, and the air guide hood 43 is used as an air collecting structure during exhaust. At this time, one end of the air guide hood 43 is set to be cylindrical, and the other end of the air guide hood 43 is set to be flat and rectangular. During installation, the end of the air guide hood 43 arranged in a flat rectangular shape is connected and communicated with the exhaust port 23, so that the air entering the air guide hood 43 can be discharged from the exhaust port 23 through its flat end. In addition, the end of the air guide hood 43 arranged in a cylindrical shape is connected to the installation cavity 11 above the partition 41, and a fan 42 is installed therein, that is, the end of the air guide hood 43 arranged in a cylindrical shape is used as the installation carrier of the fan 42, which facilitates the installation and fixation of the fan 42, and also forms an air intake port, providing conditions for the discharge of heat in the installation cavity 11.

[0034] More specifically, one end of the air guide cover 43 connected to the exhaust port 23 is inserted into the exhaust port 23, so that the air guide cover 43 and the exhaust port 23 are plug-in connected, and the installation is more convenient. At the same time, a plurality of protrusions 431 are provided on the outer wall of the end of the air guide cover 43 connected to the exhaust port 23, and a plurality of card slots 231 corresponding to the plurality of protrusions 431 are provided on the inner wall of the exhaust port 23. When installing, the protrusions 431 are inserted into the corresponding card slots 231, so that the air guide cover 43 and the exhaust port 23 are plug-in connected, and the disassembly and assembly are more convenient, which is conducive to the cleaning and maintenance in the later stage.

[0035] More specifically, a filter screen 6 is also provided in the air inlet 24. At this time, the filter screen 6 is embedded in the air inlet 24, so that the filter screen 6 is hidden in the air inlet 24, which improves the aesthetic appearance. At the same time, the air entering the installation cavity 11 can be filtered, and foreign impurities can be further prevented from entering the installation cavity 11 and affecting the operation of the electronic components in the installation cavity 11. In addition, a protruding limiting step is provided on the edge of the end of the air inlet 24 close to the inner side of the installation cavity 11, that is, a partial blocking structure is formed at the end of the air inlet 24 close to the inner side of the installation cavity 11 through the limiting step. During installation, one end of the filter screen 6 is pressed against the limiting step, that is, the limiting step prevents the filter screen 6 from being sucked into the installation cavity 11, and the stability of the filter screen 6 installed at the air inlet 24 is maintained.

[0036] More specifically, horizontally arranged slide rail assemblies 7 are provided on both sides of the housing 1 and located at the front opening, that is, the two slide rail assemblies 7 are symmetrically arranged on both sides of the housing 1. At this time, an embedding hole is also provided on the corresponding cabinet. During installation, the slide rail assemblies 7 on both sides of the housing 1 are also installed on the inner wall of the embedding hole of the cabinet, that is, the housing 1 is installed in the embedding hole of the corresponding cabinet through the slide rail, forming a structure similar to a drawer, so that the digital display adjustable temperature and humidity control device provided in this embodiment can slide on the corresponding cabinet, which is convenient for wiring and subsequent inspection and maintenance. It is worth pointing out that the slide rail assembly 7 is a common structure on the market, such as a drawer guide rail, etc., which can be purchased and used directly, so its specific structure is not repeated here.

[0037] More specifically, a wiring socket 8 is further provided on the housing 1 and on the side opposite to the front opening, that is, when the digital display adjustable temperature and humidity control device provided in this embodiment is embedded in the corresponding cabinet, the wiring socket 8 can be located in the cabinet, which is convenient for connecting with other structures in the cabinet. In addition, the wiring socket 8 is electrically connected to the control circuit board 3 to meet the use requirements of digital display and control adjustment.

[0038] More specifically, a plurality of air inlets 24 are provided at the bottom of the display and control panel 2. At this time, the plurality of air inlets 24 are arranged at intervals along the width direction of the display and control panel 2 after installation, which can also adapt to the display 21 in a rectangular structure installed on the display and control panel 2, so as to achieve reasonable use of space and improve aesthetics. At the same time, each air inlet 24 is connected to the installation cavity 11 located below the partition 41 to ensure that the use demand of large air volume intake can be met.

[0039] More specifically, a plurality of card holes 12 are provided on the side wall of the edge of the front opening of the shell 1. At this time, a plurality of card feet 25 corresponding to the card holes 12 are provided on the outer wall of the display and control panel 2. During installation, one side of the display and control panel 2 is pushed into the installation cavity 11 from the front opening of the shell 1, so that the card feet 25 can be inserted into the card holes 12 one by one, thereby realizing the card-connected installation of the display and control panel 2 on the shell 1, and the disassembly and assembly are more convenient and efficient.

[0040] As a preferred embodiment, when the air guide cover 43 is not provided, the fan 42 can be directly installed at the vent hole 411 on the partition 41. At this time, the fan 42 and the control circuit board 3 are respectively located on both sides of the partition 41, thereby avoiding the problem of mutual interference. In addition, the partition 41 can also be directly used as an installation carrier for the fan 42, so that the structure is more efficiently utilized and the manufacturing cost is lower.

[0041] The digital display adjustable temperature and humidity control device provided in the present embodiment includes a shell 1, a display and control panel 2, a control circuit board 3 and an active heat dissipation duct; a partition 41 with a vent 411 is arranged in the installation cavity 11 of the shell 1, and one side of the display and control panel 2 is exposed outside the shell 1 and an exhaust port 23 and an air inlet 24 are arranged at the upper and lower parts thereof respectively, and a fan 42 is arranged in the installation cavity 11 and at the exhaust port 23.
