The sealed door 2 is provided with a sealing protrusion 17, and a sealing ring 18 is fixedly installed on the periphery of the sealing protrusion 17. The cabinet 1 is provided with an isolation box 19 in the heat dissipation chamber 5, and the isolation box 19 is connected to the assembly chamber 4 through the wire assembly hole 20. A connection terminal 21 is fixedly installed inside the isolation box 19. A side cover 22 is fixedly installed outside the isolation box 19.

[0024] Through the above technical scheme, the utility model divides the cabinet 1 into an assembly room 4 and a heat dissipation room 5 by a partition plate 3. The assembly room 4 is used to install electronic components. An air inlet 6 and an air outlet 7 are arranged on the partition plate. The hot air inside the assembly room 4 enters the heat dissipation room 5 through the air inlet 6 driven by a fan 8. A heat exchanger 13 is installed inside the heat dissipation room 5. The heat exchanger 13 transfers the heat to the external heat dissipation fins 14. The air cooled by the heat dissipation room 5 returns to the assembly room 4 through the air outlet 7.

[0025] Embodiment 2:

[0026] like Figure 1-Figure 6 As shown, the cabinet 1 of the utility model is movably equipped with a sealed door 2. The cabinet 1 and the sealed door 2 can effectively prevent moisture and humidity from entering the cabinet 1, and prevent the electrical components inside the cabinet 1 from being corroded. A partition board 3 is fixedly installed inside the cabinet 1. The partition board 3 divides the cabinet 1 into an assembly room 4 and a heat dissipation room 5. By dividing the cabinet 1 into two chambers, the air inside the cabinet 1 can circulate and flow, reducing the temperature inside the cabinet 1. The partition board 3 is provided with an air inlet 6 and an air outlet 7. The electrical components inside the assembly room 4 are installed with a partition board 3. The heat generating element generates heat during operation, and the hot air is passed from the air inlet 6 into the heat dissipation chamber 5 through air circulation. The heat dissipation chamber 5 cools the hot air and discharges the hot air from the air outlet 7 to the assembly chamber 4. The air inlet 6 is fixedly installed with a fan 8 in the heat dissipation chamber 5. The fan 8 is the power of the air circulation inside the cabinet 1. The fan 8 is arranged at the air inlet 6 and located in the heat dissipation chamber 5, so that the air inlet 6 sucks the hot air of the assembly chamber 4 by suction, so that the hot air of the assembly chamber 4 can quickly enter the circulation, thereby improving the heat dissipation effect. A fan blade guard net 9 is fixedly installed in the assembly chamber 4, which plays a role in protecting the fan 8 and preventing construction workers from being accidentally injured by the fan 8. A partition net 10 is fixedly installed at the air outlet 7, which can prevent foreign matter from entering the heat dissipation chamber 5 and improve the cooling effect of the heat dissipation chamber 5. An assembly port 11 is provided on the side of the cabinet 1. The assembly port 11 is located in the heat dissipation chamber 5 and is fixedly connected to a heat exchanger 13 through a heat conduction block 12. A heat dissipation fin 14 is fixedly installed on the side of the cabinet 1 and is attached to the surface of the heat conduction block 12. The heat dissipation chamber 5 Its working principle is that the heat exchanger 13 collects the heat of the heat dissipation chamber 5, and the heat is introduced into the heat conductive block 12 through the copper tube. The heat conductive block 12 is installed in close contact with the external heat dissipation fins 14, so that the heat inside the heat dissipation chamber 5 is transferred to the outside through the heat dissipation fins 14, thereby achieving the heat dissipation function inside the cabinet 1. The partition plate 3 is fixedly installed with an assembly seat 15 in the assembly chamber 4, and the assembly seat 15 is fixedly installed with an assembly beam 16. Through the cooperation of the assembly seat 15 and the assembly beam 16, the construction personnel can fix the electrical components inside the cabinet 1.

[0027] The sealing door 2 of the utility model is provided with a sealing protrusion 17, and a sealing ring 18 is fixedly installed on the periphery of the sealing protrusion 17. The function of the protrusion is to facilitate the installation of the sealing ring 18 on its periphery. The periphery size of the protrusion matches the front opening of the cabinet 1, so that when the sealing door 2 is closed, the sealing ring 18 can fit tightly against the cabinet 1, thereby improving the sealing performance of the sealing door 2 and preventing moisture from entering the interior of the cabinet 1 to corrode electronic components. The combination of the sealing protrusion 17 and the sealing ring 18 improves the sealing performance and moisture-proof ability of the utility model. By fixing the sealing ring 18 on the periphery of the sealing protrusion 17, the sealing ring 18 can fit tightly with the front opening of the cabinet 1 to form an effective sealing interface. The material of the sealing ring 18 is rubber or silicone material to ensure that good sealing performance can be maintained under various environmental conditions.

[0028] The cabinet 1 of the utility model is provided with an isolation box 19 in the heat dissipation chamber 5, and the isolation box 19 is connected to the assembly chamber 4 through the wire assembly hole 20. The isolation box 19 allows the inside of the cabinet 1 to be connected with external wires, and the external wires are electrically connected to the electronic components inside the cabinet 1 through the wire assembly hole 20. The isolation box 19 is added in the heat dissipation chamber 5 to improve the electrical safety and protection performance of the equipment. The isolation box 19 enables effective electrical connection between the external wires and the electronic components inside the cabinet 1, and also provides an additional moisture-proof barrier for the equipment.

[0029] The utility model has a connection terminal 21 fixedly installed inside the isolation box 19. The connection terminal 21 is convenient for connecting to external wires. The connection terminal 21 is a kind of electrical connection element commonly used in electrical engineering. They are usually made of conductive materials and have good conductive properties and mechanical strength. Installing the connection terminal 21 inside the isolation box 19 can facilitate the rapid connection and disconnection of the wires, greatly improving the assembly efficiency and maintenance convenience of the electrical control system. Since the connection terminal 21 is located inside the isolation box 19, such a layout effectively protects the terminal from direct influences of the external environment, such as moisture, dust and mechanical damage. This not only helps to extend the service life of the connection terminal 21, but also ensures the stability and reliability of the electrical connection.

[0030] The outer side of the isolation box 19 of the utility model is fixedly mounted with a side cover 22 to protect the connection terminals 21 inside the isolation box 19 and ensure the reliability and safety of the electrical connection.

[0031] The heat exchanger of the utility model includes a heat-conducting copper tube and a heat-conducting plate. The heat-conducting plate is fixedly mounted on the heat-conducting copper tube, and an angle of 80 degrees is formed between the two, so that the direction of the airflow passing through the heat-conducting plate is changed, so that the air produces a mixing effect inside the heat dissipation chamber, and the cooling effect is effectively improved. The angle of 80 degrees between the heat-conducting plate and the heat-conducting copper tube is such that when hot air passes through the heat-conducting plate, the direction of the airflow changes due to the inclination angle of the heat-conducting plate, forming a stirring effect. This stirring helps to break the laminar structure of the air in the heat-dissipating chamber, so that the hot air and the cold air are more fully mixed, thereby improving the efficiency of the heat exchange. In addition, this design also helps to reduce the hot spot phenomenon inside the heat-dissipating chamber, that is, the problem of excessive temperature in certain areas. By improving the air flow, the temperature distribution in the heat-dissipating chamber can be made more uniform, thereby protecting the electrical components from damage due to local overheating.
