Under high load, hotspot cooling is insufficient, while under low load, the fans operate at high speeds, generating considerable noise. Furthermore, the high-temperature exhaust air generated during operation is directly discharged, failing to recover or utilize this waste heat. All temperature sensors require unified power supply from the mainboard, increasing the overall power load. Summary of the Invention

Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figures 1 to 5 This invention provides a technical solution: a partitioned airflow cooling device for a seven-port network security device, comprising a security device host 1. This device is suitable for high-power special network security devices with heavy loads and severe heat generation. Multiple shields 13 are arranged inside the security device host 1, covering each heat-generating electronic component. The enclosed space formed by the shields 13 constitutes an independent heat dissipation partition. The outer contour of the shields 13 is designed to fit the actual arrangement of the internal electronic components, avoiding interference with component assembly. The heat dissipation partitions are divided into a primary heat dissipation partition, a secondary heat dissipation partition, and a tertiary heat dissipation partition. The primary heat dissipation partition houses the core heat-generating components with the highest heat output, the secondary heat dissipation partition houses components with the next highest heat output, and the tertiary heat dissipation partition houses components with the lowest heat output.
[0023] A top shell 2 is mounted on top of the main unit 1 of the safety device. Inside the top shell 2, a complete heat dissipation mechanism is arranged to guide and dissipate heat to each independent heat dissipation zone. Each heat dissipation zone is connected to an internal air intake pipe 14 and an internal exhaust pipe 15 at both ends. The routing of the internal air intake pipe 14 and the internal exhaust pipe 15 follows the layout of the internal components of the main unit to avoid interfering with the normal operation of the internal electronic components. An air jet is installed at the end of the internal air intake pipe 14, which blows directly towards the heat-generating elements inside the zone. An exhaust fan is installed on the internal exhaust pipe 15 to extract the hot air from inside the zone. Temperature sensors are installed inside the cavity of each heat dissipation zone to collect the internal temperature signal in real time.
[0024] The heat dissipation mechanism includes two sets of air intake chambers 3 arranged symmetrically on the left and right. One end of the air intake chamber 3 penetrates the side wall of the top shell 2, and an air inlet 4 is set at this end. An air intake fan is installed inside the air inlet 4. The other end of the air intake chamber 3 is connected to a connecting block 5. Three mounting holes 6 are opened on the connecting block 5, namely a primary mounting hole, a secondary mounting hole, and a tertiary mounting hole. The primary mounting hole, the secondary mounting hole, and the tertiary mounting hole are respectively connected to the primary heat dissipation zone, the secondary heat dissipation zone, and the tertiary heat dissipation zone. The end of the mounting hole 6 is connected to a connecting pipe 7, and the connecting pipe 7 is connected to the corresponding internal air intake pipe 14.
[0025] An inner plate 8 is fixedly installed inside each mounting hole 6, and several air passage holes 9 are formed on the inner plate 8. An adjusting motor 10 is fixed inside the cavity of the mounting hole 6, and the output end of the adjusting motor 10 is connected to a rotating shaft 11. The rotating shaft 11 passes through the inner plate 8, and several baffles 12 are fixed to the side wall of the rotating shaft 11. The adjusting motor 10 drives the rotating shaft 11 to rotate, which in turn drives the baffles 12 to rotate synchronously. When the baffles 12 rotate to the position of covering the air passage holes 9, the airflow cross section is reduced, and the air intake volume is reduced. When the baffles 12 and the air passage holes 9 are completely offset from each other, all the air passage holes 9 are open, and the air intake volume reaches the maximum.
[0026] The heat dissipation mechanism also includes a central air box 16, with air intake pipes 17 connected to both sides of the central air box 16. The internal exhaust pipes 15 of each heat dissipation zone are connected to the corresponding air intake pipes 17. The hot air discharged from each zone is collected and converged into the central air box 16 via the internal exhaust pipes 15 and air intake pipes 17. An installation cover 18 is installed on the upper surface of the air inlet chamber 3, and a thermoelectric generator is arranged on the bottom surface of the installation cover 18. A side air duct 19 is connected between the installation cover 18 and the central air box 16. The high-temperature hot air collected by the central air box 16 is sent into the internal cavity of the installation cover 18 via the side air duct 19, and the hot air acts on the hot end of the thermoelectric generator. The room-temperature cold air entering the air inlet chamber 3 comes into contact with the cold end of the thermoelectric generator, and the hot and cold ends form a temperature difference to realize thermoelectric conversion. The thermoelectric generator is electrically connected to the battery and various temperature sensors. Under high-power conditions, the generated electricity can power the temperature sensors, and the excess electrical energy is stored in the battery. The top of the mounting cover 18 is provided with an exhaust pipe 20, and a through hole is opened on the top shell 2 that is aligned with the position of the exhaust pipe 20. The hot air is finally discharged outward through the exhaust pipe 20 through the top shell 2.
[0027] This invention also provides a heat dissipation method for a partitioned airflow cooling device for a seven-port network security equipment: S1: Temperature sensors are placed inside each heat dissipation zone to collect the temperature inside the cavity of the first-level heat dissipation zone, the second-level heat dissipation zone, and the third-level heat dissipation zone in real time, and obtain the real-time temperature data of each zone.
[0028] S2: The collected temperature data is transmitted to the main control unit of the device and compared with the preset temperature threshold to determine whether the current working state of the device is low power working mode or high power working mode. The two modes are mutually exclusive, and the device only operates in one mode at a time.
[0029] S3: Execute the corresponding heat dissipation control strategy based on the judgment result: When the system is determined to be in low-power operating mode: the overall heat generation of the unit is low, and the heat dissipation requirement is small; the control motor 10 drives the rotating shaft 11 and the baffle 12 to rotate, and the baffles 12 of each mounting hole partially block the air passage 9, reducing the air intake flow area of each heat dissipation zone; at the same time, the intake fan of the air inlet 4 and the exhaust fan on the internal exhaust pipe 15 are controlled to run at low speed. The air volume is reduced while meeting the heat dissipation requirements, thereby reducing the overall operating noise of the unit.
[0030] When the system is determined to be in high-power operating mode: the entire unit generates significant heat, with the heat output of the primary and secondary heat dissipation components increasing dramatically, while the heat output of the tertiary heat dissipation components remains at a relatively low level; the control motor 10 drives the baffle 12 to rotate, completely offsetting the baffle 12 inside the primary and secondary mounting holes from the air vents 9, ensuring that all air vents 9 are open, thus increasing the air intake of the primary and secondary heat dissipation zones; the baffle of the tertiary mounting hole remains partially blocked, reducing the air intake of the tertiary heat dissipation zone, and prioritizing the supply of limited air to the high-heat primary and secondary heat dissipation zones; at the same time, the intake fan and exhaust fan speeds are increased to increase airflow.
[0031] Outside cold air enters the air intake chamber 3 through the air inlet 4, passes through the mounting hole 6 of the connecting block 5, the connecting pipe 7, and the inner air intake pipe 14 in sequence, and is blown by the jet head to the heating components inside the partition to remove heat; the heated hot air, under the action of the exhaust fan, flows through the inner exhaust pipe 15 and the air collection pipe 17 into the central air box 16; the hot air is then introduced into the mounting cover 18 through the side air duct 19, acting on the hot end of the thermoelectric generator, relying on the room temperature cold air entering the air intake chamber 3 to form a temperature difference to generate electricity, which can power the temperature sensor, and the excess electricity is stored in the battery; the hot air after completing the energy exchange is finally discharged to the outside through the exhaust pipe 20 through the top shell 2.
[0032] This invention discloses a partitioned airflow cooling device and method for a seven-port network security device. The complete device mainly includes a security device host 1, a top shell 2, an air inlet 3, an air inlet 4, a connecting block 5, a mounting hole 6, a connecting pipe 7, an inner plate 8, air vents 9, an adjusting motor 10, a rotating shaft 11, a baffle 12, a barrier cover 13, an inner air intake pipe 14, an inner exhaust pipe 15, a central air box 16, a collection pipe 17, a mounting cover 18, a side air duct 19, and an exhaust pipe 20. The host of this invention is divided into three independent cooling zones by the barrier cover 13. The shape of the barrier cover is adapted to the contours of the internal components, and the pipe layout avoids interference between components. The adjusting motor 10 drives the baffle 12 to rotate, changing the effective flow area of the air vents 9, thereby distributing the airflow to different cooling zones. During equipment operation, temperature sensors collect real-time temperatures from each zone, distinguishing between low-power and high-power mutually exclusive operating modes based on temperature thresholds. In low-power mode, the overall airflow is reduced, and the fan operates at low speed to minimize noise. In high-power mode, priority is given to supplying large airflow to the primary and secondary high-heat-generating zones, while airflow is restricted to the tertiary zone with lower heat generation. The hot air exhausted from each zone is collected and transported to the mounting cover 18, where waste heat is recovered using a thermoelectric generator to power the temperature sensors and store excess electricity in the battery. This invention solves the problems of unreasonable airflow distribution and inability to recover waste heat in traditional unified air duct systems. Independent zone-based airflow cooling provides good adaptability to various operating conditions, making it suitable for high-power, high-heat-generating special seven-port network security equipment, and possesses promising application prospects.
