[0001] This utility model relates to the field of electrical cabinet technology, specifically to an electrical cabinet with temperature and humidity control functions. Background Technology
[0002] In modern industrial and commercial applications, electrical cabinets are widely used to protect and manage electrical equipment. Traditional electrical cabinets mainly rely on physical isolation and mechanical protection. However, under conditions such as high temperature and high humidity, electrical equipment is easily affected, leading to a decline in performance or failure. In this case, by regulating the temperature and humidity inside the electrical cabinet, the electrical equipment can be kept in a suitable environment, thereby improving its stability and ensuring that it operates in a high-efficiency state.
[0003] When regulating the temperature inside an electrical cabinet, most methods involve using a fan to deliver cool air from the outside into the cabinet to cool it down. However, under high-temperature conditions, the outside temperature is also high, and the fan will deliver hot air, which may prevent the temperature inside the cabinet from being effectively reduced. Therefore, this solution provides an electrical cabinet with temperature and humidity control functions to address the aforementioned problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, an electrical cabinet with temperature and humidity control functions is provided. This technical solution addresses the issue mentioned in the background art where, when regulating the internal temperature of an electrical cabinet, most methods involve using a fan to deliver cool air from the outside to the inside of the cabinet to achieve cooling. However, under high-temperature conditions, the outside temperature is also high, and the fan will deliver hot air at a high temperature, which may result in the internal temperature of the electrical cabinet not being effectively reduced.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an electrical cabinet with temperature and humidity control functions, comprising a first cabinet, a first door mounted on the front end of the first cabinet via a hinge, a first handle fixedly mounted on the left side of the front end of the first door, a second cabinet fixedly connected to the lower end of the first cabinet, a second door mounted on the front end of the second cabinet via a hinge, a second handle fixedly mounted on the left side of the front end of the second door, a plurality of heat dissipation holes extending through the upper end of the first cabinet, a dustproof frame fixedly connected above the upper end of the first cabinet and the plurality of heat dissipation holes, a circular opening extending through the right end of the first cabinet, a cooling fan fixedly mounted inside the circular opening, a radiator fixedly mounted on the right end of the first cabinet and the right end of the circular opening, a plurality of heat dissipation pipes disposed inside the radiator, and a dustproof plate fixedly connected to the right end of the radiator.

[0008] Preferably, a mounting base is fixedly installed at the rear end of the first housing, and a controller is installed inside the mounting base. A temperature and humidity sensor is installed at the left end of the first housing, and heating blocks are fixedly connected to both the left and right sides of the first housing.

[0010] Compared with the prior art, this utility model provides an electrical cabinet with temperature and humidity control functions, which has the following beneficial effects:
[0011] This invention monitors temperature changes inside the electrical cabinet using a temperature and humidity sensor.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0019] Reference Figures 1-4 As shown, an electrical cabinet with temperature and humidity control functions includes a first enclosure 1. A first door 2 is hinged to the front of the first enclosure 1, and a first handle 3 is fixedly installed on the left side of the front of the first door 2. A second enclosure 4 is fixedly connected to the lower end of the first enclosure 1. A second door 5 is hinged to the front of the second enclosure 4, and a second handle 6 is fixedly installed on the left side of the front of the second door 5. Several ventilation holes 7 are provided through the upper end of the first enclosure 1. A dustproof frame 8 is fixedly connected to the upper end of the first enclosure 1 and above the ventilation holes 7. A circular opening 9 is provided through the right end of the first enclosure 1, and a cooling fan 10 is fixedly installed inside the circular opening 9. A radiator 11 is fixedly installed at the right end of the first housing 1 and the right end of the circular opening 9. Since the radiator 11 still allows air to flow through when it is closed, when the outside temperature is low, the cooling fan 10 delivers outside air into the interior of the first housing 1 to cool it down. When the outside temperature is high, the controller 21 turns on the radiator 11, and the radiator 11 starts the refrigerant circulation. The refrigerant inside the heat pipe 13 absorbs heat, thereby reducing the temperature of the air passing through the radiator 11 and lowering the temperature of the air entering the first housing 1. The radiator 11 has several heat pipes 13 inside, and a dustproof plate 12 is fixedly connected to the right end of the radiator 11.
[0020] Reference Figure 2 and Figure 4As shown, rectangular openings 14 are provided at the lower end of the first housing 1 and the upper end of the second housing 4. A dehumidifier 15 is fixedly connected to the bottom of the second housing 4. The dehumidifier 15 has a water collection tank inside. Air from the first housing 1 is drawn into the dehumidifier 15 through the input end, cooled by the cooling system, causing the moisture in the air to condense into water droplets that fall into the water collection tank. The output end of the dehumidifier 15 is located inside the rectangular opening 14. A humidifier 16 is provided at the left end of the dehumidifier 15. The lower end of the humidifier 16 is fixedly connected to the bottom of the second housing 4. An output pipe 17 is provided on the upper left side of the humidifier 16. The humidifier 16 converts water into steam and then delivers it to the interior of the first chamber 1 through the output pipe 17, thereby increasing the humidity inside the first chamber 1. The upper end of the output pipe 17 extends into the interior of the first chamber 1. A water inlet pipe 18 is fixedly connected to the upper right side of the humidifier 16. The upper end of the water inlet pipe 18 extends into the interior of the first chamber 1 and is threadedly connected to a sealing cap 19. A mounting base 20 is fixedly installed at the rear end of the interior of the first chamber 1. A controller 21 is installed inside the mounting base 20. The controller 21 can be a Siemens model. S7-1200, the controller 21 can be any existing controller 21 that can achieve this function, without restriction. Furthermore, the controller 21 is electrically connected to the temperature and humidity sensor 22, the cooling fan 10, the radiator 11, the electric heating wire 26, the humidifier 16, and the dehumidifier 15. The temperature and humidity sensor 22 is located at the left end of the interior of the first housing 1. The temperature and humidity sensor 22 can be of model AM2301. Any existing sensor that can achieve this function can be used for the temperature and humidity sensor 22, without restriction. Heating blocks 23 are fixedly connected to the left and right sides of the interior of the first housing 1. The heating blocks 23 have mounting grooves 24 on their inner sides. Mounting plates 25 are fixedly connected to the front and rear ends of the mounting grooves 24. An electric heating wire 26 is arranged between the two mounting plates 25. The heat generated by the electric heating wire 26 is transferred to the interior of the first housing 1 through the heat-conducting plate 27, thereby regulating the temperature inside the first housing 1. The heat-conducting plate 27 is arranged on the inner side of the two mounting plates 25, and the outer side of the heat-conducting plate 27 abuts against the electric heating wire 26.
[0021] The working principle and usage process of this utility model are as follows: During use, the temperature and humidity sensor 22 monitors the interior of the first chamber 1, maintaining the temperature and humidity within a suitable range. When the humidity inside the first chamber 1 is too high or too low, the temperature and humidity sensor 22 transmits a signal to the controller 21. At this time, the controller 21 controls the dehumidifier 15 or humidifier 16 to adjust the humidity inside the first chamber 1, restoring it to a suitable range. When the temperature and humidity sensor 22 detects that the temperature inside the first chamber 1 is too low, the controller 21 controls the electric heating wire 26 to generate heat. The generated heat is transferred to the interior of the first chamber 1 through the heat-conducting plate 27. This can increase the internal temperature of the first housing 1. When the internal temperature of the first housing 1 is high, the controller 21 controls the cooling fan 10 to deliver external air into the first housing 1 through the circular opening 9. When the external temperature is also high, the controller 21 controls the radiator 11 to process the passing air. The high-temperature air passes through the heat dissipation pipe 13 inside the radiator 11. The refrigerant flowing inside the heat dissipation pipe 13 absorbs the heat in the air, thus lowering the temperature of the air entering the first housing 1. After the air enters the first housing 1, it absorbs the internal heat and becomes hot air. The hot air naturally rises and is discharged from the first housing 1 through the heat dissipation hole 7, thereby lowering the internal temperature of the first housing 1.
[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
