[0015] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0016] Example See Figures 1 to 7This utility model provides a switch cabinet with temperature and humidity monitoring function, including a cabinet body 1, a cabinet door 2, a mounting plate 3, a temperature and humidity monitoring unit 4, an air inlet pipe 8, and a temperature and humidity regulating component 15. The cabinet body 1 is hinged to the cabinet door 2, which has a front ventilation port 27 and a rear ventilation port 28, to realize air circulation inside the cabinet body 1. This works in conjunction with the temperature and humidity regulating component 15 to regulate the temperature and humidity of the air inside the cabinet body 1, maintaining a suitable temperature and humidity level. The cabinet body 1 has an air chamber 29 and a mounting chamber 30. The mounting plate 3 is installed in the mounting chamber 30, dividing the mounting chamber 30 into a front chamber 31 and a rear chamber 32. Electrical equipment is installed on the mounting plate 3 facing the front chamber 31. The mounting plate 3 has several through holes 33 for easy access to the cabinet body 1. The internal air circulation is achieved through several inclined through holes 33, with the inlet of the through holes 33 at the lower end and the outlet at the higher end. The input end of the air inlet pipe 8 is connected to the ventilation chamber 29 and the rear ventilation port 28, allowing air to be selected to enter either the ventilation chamber 29 or the rear ventilation port 28 depending on the actual situation. The output end of the air inlet pipe 8 is connected to the temperature and humidity regulating component 15 installed in the rear chamber 32. The temperature and humidity regulating component 15 is connected to several through holes 33. The front chamber 31 is connected to the ventilation chamber 29, and the ventilation chamber 29 is connected to the front through hole 33. The temperature and humidity monitoring unit 4 is used to monitor the temperature and humidity of the air inside and outside the cabinet 1. The temperature and humidity monitoring unit 4 is electrically connected to the control unit 7, which is electrically connected to the temperature and humidity regulating component 15 and the air inlet pipe 8. The control unit 7 is a PLC controller.

[0017] The temperature and humidity monitoring unit 4 monitors the air temperature and humidity in the installation chamber 30, the air chamber 29, and outside the cabinet 1. When the air temperature or humidity in the installation chamber 30 exceeds a threshold, it controls the air inlet duct 8 and the temperature and humidity regulating component 15 to operate. Furthermore, based on a comparison between the air temperature and humidity in the air chamber 29 and the air temperature and humidity outside the cabinet 1, it controls the air inlet duct 8 to select either air intake through the air chamber 29 or the rear ventilation opening 28. That is, when the air temperature in the air chamber 29 is higher than the air temperature outside the cabinet 1, the air inlet duct 8 intakes air through the rear ventilation opening 28; otherwise, it selects air intake through the air chamber 29. When the air humidity in the air chamber 29 is higher than the air temperature outside the cabinet 1, the air inlet duct 8 intakes air through the rear ventilation opening 28. When the air humidity outside the cabinet 1 is within acceptable limits, the air intake duct 8 draws air in through the rear vent 28; otherwise, the air intake chamber 29 is selected. The air flows through the air intake duct 8 and passes through the temperature and humidity regulating component 15. After the temperature or humidity is regulated by the temperature and humidity regulating component 15, the air is blown upwards through the through hole 33 towards the front chamber 31, effectively cooling or dehumidifying the front chamber 31. The air inside the cabinet 1 flows upwards into the air chamber 29. In this state, if the air intake duct 8 draws air in through the rear vent 28, the air entering the air chamber 29 is discharged through the front vent 27, reducing the energy consumption of the temperature and humidity regulating component 15 in regulating the temperature and humidity inside the cabinet 1.

[0018] The temperature and humidity monitoring unit 4 includes multiple temperature sensors 5 and multiple humidity sensors 6. The multiple temperature sensors 5 and multiple humidity sensors 6 are electrically connected to the control unit 7. Temperature sensors 5 and humidity sensors 6 are installed in the installation chamber 30, the air chamber 29 and the cabinet 1 respectively, which can monitor the air temperature outside the installation chamber 30, the air chamber 29 and the cabinet 1.

[0019] The temperature and humidity control assembly 15 includes a dehumidifier 16, a cooler 17, a fan 18, and an air outlet hood 19. The input ends of the dehumidifier 16 and the cooler 17 are respectively connected to the air inlet pipe 8 through a first connecting pipe (not shown). The output end of the dehumidifier 16 is connected to the dehumidification pipe 20, and the output end of the cooler 17 is connected to the temperature regulating pipe 21.

The fan 18 is connected to the air outlet hood 19, and the air outlet hood 19 is connected to several through holes 33. The output end of the dehumidification pipe 20 is also connected to the input and output of the cooler 17 through a second connecting pipe 23.

[0020] Solenoid valves (not shown) are connected to the first connecting pipe connecting the input ends of the dehumidifier 16 and the cooler 17, respectively. Solenoid valves (not shown) are also connected to the dehumidification pipe 20 and the second connecting pipe 23, respectively. The solenoid valves (not shown) are electrically connected to the control unit 7. Depending on the purpose of dehumidification or cooling, the solenoid valves (not shown) control the flow of air into the dehumidifier 16 or the cooler 17 to dehumidify or cool the incoming air. When cooling is still required after dehumidification, the solenoid valve (not shown) on the second connecting pipe 23 is opened and the solenoid valve (not shown) on the dehumidification pipe 20 is closed. The dehumidified air flows through the cooler 17 for cooling. Under the action of the fan 18, the dehumidified or cooled air enters the air outlet hood 19. The air outlet hood 19 is connected to several through holes 33, thereby blowing air through the through holes 33.

[0021] The air inlet duct 8 includes a first air duct 9, a second air duct 10, a four-way pipe 14, a front air hood 12, and a rear air inlet hood 13. The front air hood 12 is connected to the first air duct 9, and the rear air inlet hood 13 is connected to the second air duct 10. The free ends of the first air duct 9 and the second air duct 10 are connected to two ends of the four-way pipe 14.

Solenoid valves (not shown) are respectively connected to the connection points of the free ends of the first air duct 9 and the second air duct 10 and the four-way pipe 14. The solenoid valves (not shown) are connected to the control unit 7 to control the opening / closing of the corresponding solenoid valves (not shown), thereby realizing the selection of the air chamber 29 or rear ventilation and rear air intake.

[0022] The second air duct 10 includes two second air ducts a24 and a second three-way pipe 25. One end of each of the two second air ducts a24 is connected to the rear air intake hood 13. The free ends of the two second air ducts a24 are connected to two ends of the second three-way pipe 25. The free ends of the second three-way pipe 25 are connected to the four-way pipe 14 through a pipe. Air from the rear air intake hood 13 is drawn in through the two second air ducts a24. The air enters the temperature and humidity regulating component 15 after passing through the three-way pipe and the four-way pipe 14 in sequence.

[0023] A plurality of first air guide plates 26 are equidistantly arranged inside the rear ventilation opening 28. The plurality of first air guide plates 26 are inclined and tilted downward from left to right.

[0024] The front ventilation opening 27 is equipped with a mesh 35, which plays a certain role in dust prevention.
