[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 2 and Figure 3 As shown, the present invention is a temperature-controlled and dehumidification integrated power switch cabinet, comprising a cabinet body 1, a main control component 2 is installed on the top of the cabinet body 1, and an auxiliary component 3 is installed on the bottom of the cabinet body 1;

[0039] The main control assembly 2 includes a first shell 21 and a second shell 22. The second shell 22 is arranged on both sides of the first shell 21. A cavity tube 23 is connected between the second shell 22 and the first shell 21. A heat conducting pipe 24 is provided through the upper end of the cabinet 1. Both ends of the heat conducting pipe 24 are respectively connected to the cavity tubes 23 on both sides. The first piston rod 231 and the second piston rod 234 for opening and closing control are slidably connected at both ends of the cavity tube 23.

[0040] The auxiliary component 3 includes a bottom shell 31 , a temperature sensor 32 and a humidity sensor 33 are installed at the upper end of the bottom shell 31 , and a suction fan 311 for supplying and exhausting air is installed inside the bottom shell 31 .

[0041] The working principle of the present invention is as follows: the main control component 2 transfers heat to the cavity tubes 23 on both sides through the heat pipe 24, thereby causing the gas in the cavity tubes 23 to contract or expand, thereby driving the movement of the first piston rod 231 and the second piston rod 234, thereby realizing the on-off control of the fans inside the first shell 21 and the second shell 22, and at the same time cooperating with the suction fan 311 in the auxiliary component 3 to realize the temperature and humidity control inside the cabinet 1. When the temperature is too high, the gas in the cavity 23 expands, and the first piston rod 231 and the second piston rod 234 move away from each other. At this time, the first shell 21 does not operate, and the second shell 22 draws air from the inside of the cabinet 1, and the suction fan 311 blows air upward, so that the hot air flow inside the cabinet 1 is discharged in the ascending direction; when the temperature is too low and the humidity is high, the gas in the cavity 23 contracts, and the first piston rod 231 and the second piston rod 234 move closer to each other. At this time, the second shell 22 does not operate, and the first shell 21 blows air into the inside of the cabinet 1, and the suction fan 311 draws air from the inside of the cabinet 1, so that the humid and cold air inside the cabinet 1 is discharged in the sinking direction.

[0042] like Figure 4 and Figure 5As shown, a heating control box 211 and a ventilation control box 212 are respectively provided on both sides of the first shell 21, the first piston rod 231 on the left side penetrates the corresponding heating control box 211, and the first piston rod 231 on the right side penetrates the corresponding ventilation control box 212, the ends of the two first piston rods 231 are connected to a first conductive plate 232, and the two first conductive plates 232 are provided with a first contact end 233 on the side away from the first shell 21, a heating conductive sheet 213 is provided inside the heating control box 211 opposite to the first contact end 233, and a ventilation conductive sheet 214 is provided inside the ventilation control box 212 opposite to the first contact end 233.

[0043] Furthermore, a first fan 215 is installed inside the first shell 21, and the first fan 215 is connected to the heater 216 through a conduit. The outlet end of the first fan 215 is connected to the first air outlet duct 217, and the first air outlet duct 217 runs through the bottom of the first shell 21. The inlet end of the heater 216 is connected to the first air inlet plate 218 through a conduit, and the first air inlet plate 218 is installed on the upper end surface of the cabinet 1.

[0044] Furthermore, the heating conductive sheet 213 is electrically connected to the heater 216 , and the ventilation conductive sheet 214 is electrically connected to the first fan 215 .

[0045] In specific applications of this embodiment, the heater 216 in the first shell 21 is heated by a resistance wire, and the first shell 21 is mainly used for temperature and humidity control at low temperatures: when the temperature is too high, the first piston rod 231 approaches the first shell 21, and the first contact end 233 is disconnected from the heating conductive sheet 213 and the ventilation conductive sheet 214; when the temperature is too low and the humidity is too high, the first piston rod 231 is away from the first shell 21, and the two first contact ends 233 are respectively in contact with the heating conductive sheet 213 and the ventilation conductive sheet 214 to realize the passage, and the heater 216 starts to heat the airflow, and at the same time, the first fan 215 starts to blow heated warm air into the cabinet 1 through the first air outlet duct 217, thereby effectively removing moisture and raising the temperature at the same time, ensuring the normal operation of the electrical components.

[0046] like Figure 4 As shown, an air supply control box 221 is provided on the side of the second shell 22 close to the cavity 23, the second piston rod 234 passes through the corresponding air supply control box 221, the end of the second piston rod 234 is connected to the second conductive plate 235, the second conductive plate 235 is provided with a second contact end 236 on the side close to the second shell 22, and an air supply conductive sheet 222 is provided inside the air supply control box 221 opposite to the second contact end 236.

[0047] Furthermore, a second fan 223 is installed inside the second shell 22, and the air supply conductive sheet 222 is electrically connected to the second fan 223. The inlet end of the second fan 223 is connected to a second air inlet plate 225, and the second air inlet plate 225 is installed at the bottom of the second shell 22. The outlet end of the second fan 223 is connected to a second air outlet duct 224, and the second air outlet duct 224 passes through the upper end surface of the cabinet 1.

[0048] In specific applications of this embodiment, the operation of the second fan 223 in the second shell 22 is controlled by the on-off control of the air supply conductive sheet 222, and the second shell 22 is mainly used for temperature and humidity control at high temperatures: when the temperature is too high, the second piston rod 234 approaches the second shell 22, at which time the second contact end 236 contacts the air supply conductive sheet 222 to achieve a passage, and the second fan 223 starts to run, extracting the hot air in the cabinet 1 through the second air inlet plate 225 and discharging it to the outside, thereby adjusting the internal temperature of the cabinet 1; when the temperature is too low, the second piston rod 234 moves away from the second shell 22, at which time the second contact end 236 is disconnected from the air supply conductive sheet 222.

[0049] like Figure 3 As shown, one end of the suction fan 311 is connected to the air dispersion plate 312 through a conduit, and the air dispersion plate 312 is installed on the upper end surface of the bottom shell 31. The other end of the suction fan 311 is connected to the dehumidification box 313 through a conduit. Both ends of the dehumidification box 313 are connected to the ventilation pipe 314. The ventilation pipe 314 passes through the bottom shell 31 and the cabinet 1 and extends to the outside of the cabinet 1.

[0050] In specific applications of this embodiment, the auxiliary component 3 can cooperate with the main control component 2 to realize air circulation inside the cabinet 1: when the temperature is too high, the main control component 2 starts to draw air from the inside to the outside. At this time, the temperature sensor 32 will transmit a signal to the PLC controller (not shown in the figure), and the PLC controller controls the suction fan 311 to start blowing air into the cabinet 1. The "upward suction and downward blowing" method conforms to the rising direction of the hot air flow, so that the hot air can be discharged from the cabinet 1 faster; when the temperature is too low and the humidity is too high, the main control component 2 starts to blow air from the outside to the inside. At this time, the PLC controller controls the suction fan 311 to start drawing air from the cabinet 1 according to the received temperature and humidity signals. The "upward blowing and downward suction" method conforms to the downward direction of the humid and cold air flow, so that the humid and cold air can be discharged from the cabinet 1 faster, and the dehumidification box 313 can effectively absorb the moisture of the humid and cold air.

[0051] like Figure 2 and Figure 6 As shown, connecting plates 4 are vertically arranged on both sides inside the cabinet 1, and a number of mounting plates 5 for arranging electrical components are horizontally installed between the two connecting plates 4. Both ends of the mounting plates 5 are inserted into the connecting plates 4, and positioning components 6 are arranged at the connection points between the ends of the mounting plates 5 and the connecting plates 4.

[0052] Furthermore, the positioning assembly 6 includes a positioning rod 61, which is slidably installed in a sliding groove of the mounting plate 5. The tail end of the positioning rod 61 is connected to the sliding groove through a spring 62. Positioning grooves 63 for the positioning rod 61 to be adapted and inserted are evenly spaced on one side of the connecting plate 4.

[0053] Furthermore, the upper and lower ends of the positioning rod 61 are connected to a lever 64, a slide groove 65 for the lever 64 to slide is provided on the mounting plate 5, a guide groove 66 is vertically provided on the connecting plate 4, and a guide block 67 that slides with the guide groove 66 is installed between the plug-in interfaces at the ends of the mounting plate 5.

[0054] When this embodiment is used in practice, the levers 64 at both ends of the mounting plate 5 are moved so that the positioning rods 61 are disengaged from the positioning grooves 63, thereby releasing the positioning effect on the mounting plate 5. At this time, the mounting plate 5 can slide up and down along the connecting plate 4. At the same time, since the guide blocks 67 are limited and guided by the guide grooves 66, the mounting plate 5 can maintain horizontal stability during the sliding process. When sliding to a suitable height, the levers 64 are released, and the positioning rods 61 are re-adapted and inserted into the corresponding positioning grooves 63 to achieve limited fixation of the mounting plate 5. Therefore, the height position of the mounting plate 5 and the spacing between adjacent mounting plates 5 can be adjusted according to the installation space requirements of the electrical components, so as to adapt to electrical components of different sizes. In addition, the adjustment method is flexible and the adjustment process is stable, which greatly improves the practical performance.

[0055] When the present invention is in use, in combination with the principle that hot air flows upward and cold air flows downward, the main control component 2 and the auxiliary component 3 realize a "one suction and one blowing" cooperation mode: when the temperature is too low and the humidity is heavy, warm air is introduced into the cabinet 1 by the first shell 21, and the suction fan 311 at the bottom is cooperated to discharge air, so that the direction of the warm air flow is consistent with the sinking direction of the wet and cold air flow, which is conducive to the discharge of wet and cold air; when the temperature is too high, the first shell 21 draws air from the cabinet 1, and the suction fan 311 at the bottom is cooperated to blow air, so that the flow air flow direction is consistent with the rising direction of the hot air flow, which is conducive to the discharge of hot air, so that the entire internal space of the cabinet 1 forms a gas flow cycle, increases the temperature and humidity control range, and improves the temperature and humidity control effect; at the same time, the principle of thermal expansion and contraction is used to enable the first shell 21 and the second shell 22 to realize automatic real-time switching of the operating state according to different temperature and humidity environments; the positioning and adjustment functions of the mounting rod are realized by the positioning component 6, so that the height and spacing of the mounting plate 5 can be adjusted to adapt to electrical components of different sizes.
