[0002] A shielded cabinet is a type of cabinet, also known as an electromagnetic shielding cabinet. Shielded cabinets can be used to house computers and can prevent electromagnetic waves from harming people, effectively suppress the leakage of electromagnetic information from computers, and prevent external strong electromagnetic interference from affecting the normal operation of computers.

[0003] Existing shielded cabinets lack cooling mechanisms during use, leading to excessively high internal temperatures that can damage internal components and reduce their lifespan. To address this, we propose a shielded cabinet with a cooling mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a shielded cabinet with a cooling mechanism. This mechanism solves the problem that existing shielded cabinets lack a cooling mechanism during use, leading to excessively high internal temperatures, which can damage internal components and reduce their lifespan.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shielded cabinet with a cooling mechanism, comprising a cabinet body, a shell fixedly connected to the top of the cabinet body, a fan fixedly connected to the left side of the shell, a fixed pipe connected to the left side of the fan, a nozzle connected to the right side of the fan, a semiconductor cooling chip embedded on the left side of the top of the shell, a heat sink fixedly connected to the top of the semiconductor cooling chip, an air guide pipe connected to the right side of the shell, a hollow tube sleeved on the top of the left side of the cabinet body, a connecting pipe connected to the central axis of the right side of the cabinet body, a hollow plate provided on one side of the connecting pipe, a first shelf and a second shelf fixedly connected to the inner wall of the cabinet body from top to bottom, a hollow block connected to the bottom of the left side of the cabinet body, and a temperature sensor fixedly connected to the top of the inner cavity of the hollow block.

[0006] Preferably, a humidity sensor is fixedly connected to the right side of the top of the inner cavity of the housing, mesh plates are fixedly connected to both sides of the inner wall of the housing, dehumidifying particles are provided on one side of the mesh plate, and a buzzer is fixedly connected to the right front end of the top of the housing.

[0007] Preferably, a first solenoid valve is connected to the front of the fixed tube, a second solenoid valve is connected to the top left side of the hollow block, one side of the second solenoid valve is connected to the fixed tube, and a third solenoid valve is connected to the bottom left side of the hollow block.

[0008] Preferably, a motor is fixedly connected to the front end of the left side of the inner cavity of the first shelf, the second shelf, and the hollow plate. A lead screw is fixedly connected to the output end of the motor. A threaded sleeve is threaded onto the surface of the lead screw. A connector is fixedly connected to one side of the threaded sleeve. A corrugated pipe is connected to one side of the hollow tube, the air guide tube, and the connecting tube. One side of the connector is connected to the corrugated pipe.

[0009] Preferably, a sliding sleeve is fixedly connected to the rear side of the nozzle, and sliding rods are fixedly connected to the rear sides of the inner walls of the first shelf, the second shelf, and the hollow plate, and the inner cavity of the sliding sleeve is slidably connected to the sliding rods.

[0011] Compared with the prior art, the present invention provides a shielded cabinet with a cooling mechanism, which has the following advantages:

[0012] 1. This utility model uses an external PLC controller to set three temperature levels. When the temperature sensor detects a temperature value between the first and second set temperature values, the PLC controller controls the fan to operate, drawing gas in through a fixed pipe and a first solenoid valve. The gas is then sprayed through a nozzle onto the bottom of a semiconductor cooling chip. The semiconductor cooling chip and heat sink cool the gas, which is then expelled through a guide pipe, hollow pipe, connecting pipe, corrugated pipe, and connector, accelerating the airflow within the cabinet cavity and thus cooling the system. When the detected temperature value is between the second and third set temperature values, the third and first solenoid valves close, while the second solenoid valve opens, allowing the gas to circulate and further accelerating the cooling process. Once the detected temperature value falls below the third set temperature value, the cooling operation stops. During the cooling process, the motor also operates, driving a lead screw to rotate. The lead screw then moves a threaded sleeve, which in turn moves the connector, ensuring even gas distribution.

[0013] 2. This utility model sets the humidity value through an external PLC controller. During the gas flow process, the dehumidifying particles will dehumidify the air. When the humidity sensor detects that the humidity value is higher than the set value, the buzzer will sound to remind the staff, so as to facilitate timely replacement of the dehumidifying particles.

[0022] The specific function of this technical solution is as follows: Three temperature levels are set via an external PLC controller. When the temperature sensor 27 detects a temperature value between the first and second set temperature levels, the PLC controller controls the fan 3 to operate, drawing gas in through the fixed pipe 4 and the first solenoid valve 5. The gas is then sprayed through the nozzle 6 to the bottom of the thermoelectric cooler 9. The thermoelectric cooler 9 and the heat sink 10 cool the gas.

Example

[0023] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2 As shown, a humidity sensor 11 is fixedly connected to the right side of the top of the inner cavity of the housing 2, and mesh plates 7 are fixedly connected to both sides of the inner wall of the housing 2. Dehumidifying particles 8 are provided on one side of the mesh plate 7, and a buzzer 26 is fixedly connected to the right front end of the top of the housing 2.

[0024] The specific function of this technical solution is as follows: the humidity value is set by the external PLC controller, and the air is dehumidified by the dehumidifying particles 8 during the gas flow process. When the humidity sensor 11 detects that the humidity value is higher than the set value, the buzzer 26 will work to remind the staff, so as to facilitate timely replacement of the dehumidifying particles 8.

[0025] Working principle: Three temperature levels are set via an external PLC controller. When the temperature sensor 27 detects a temperature value between the first and second set temperature levels, the PLC controller controls the fan 3 to operate, drawing gas in through the fixed pipe 4 and the first solenoid valve 5. The gas is then sprayed through the nozzle 6 to the bottom of the thermoelectric cooler 9. The thermoelectric cooler 9 and the heat sink 10 cool the gas, which is then expelled through the air guide pipe 12, hollow pipe 16, connecting pipe 17, corrugated pipe 22, and connector 21, accelerating the airflow within the cabinet 1. The flow rate is adjusted to perform cooling. When the temperature value is detected to be between the set second and third temperature values, the third solenoid valve 25 and the first solenoid valve 5 will close, and the second solenoid valve 24 will open, which will cause the gas to circulate and thus accelerate the cooling speed. When the temperature value is detected to be lower than the set third temperature value, the cooling operation will stop. During the cooling process, the motor 18 will also work, driving the lead screw 19 to rotate, the lead screw 19 to move the threaded sleeve 20, and the threaded sleeve 20 to move the connector 21, so that the gas is evenly distributed.

[0026] The humidity value is set by the external PLC controller. During the gas flow process, the dehumidifying particles 8 will dehumidify the air. When the humidity sensor 11 detects that the humidity value is higher than the set value, the buzzer 26 will work to remind the staff, so that the dehumidifying particles 8 can be replaced in a timely manner.
