[0028] See also Figures 1 to 7 , The utility model provides a technical solution: a ventilation and heat dissipation high-voltage switch cabinet, comprising a cabinet body 1, a ventilation mechanism and a cooling mechanism, wherein;
[0029] The surface of the cabinet 1 is provided with an installation compartment 6, and the installation compartment 6 is used to install electrical components;
[0030] The ventilation mechanism includes a vent 2, a ventilation pipe 4 and an exhaust fan 5. The vent 2 is opened on the surface of the cabinet 1 and communicates with the installation bin 6. The bottom of the installation bin 6 is fixedly installed with the exhaust fan 5 through the opened air port. The ventilation pipe 4 is arranged on the cabinet 1 and communicates with the air port of the installation bin 6.
[0031] The cooling mechanism includes a cooling chamber 7, a heat sink 8 and a water pipe 9. The cooling chamber 7 is opened on one side of the cabinet 1. The heat sink 8 is detachably connected to the side of the cabinet 1 and covers the cooling chamber 7. The water pipe 9 runs through the cabinet 1 and is at least partially located in the cooling chamber 7. The end of the water pipe 9 located in the cooling chamber 7 is communicated with the cavity of the heat sink 8.
[0032] In this embodiment, through the setting of the ventilation mechanism, the exhaust fan 5 is a forward and reverse exhaust fan 5. When the exhaust fan 5 rotates forward, the air in the installation chamber 6 is sucked into the ventilation pipe 4. At this time, a negative pressure is formed in the installation chamber 6, and the outside air can enter the installation chamber 6 from the ventilation port 2 to take away the heat generated by the equipment in the installation chamber 6. The water pipe 9 passes cold water into the heat sink 8 to reduce the temperature of the heat sink 8. After the exhaust fan 5 is started in the reverse direction, the air can flow in the reverse direction, pass through the heat sink 8, cool the air through the heat sink 8, and then pass into the installation chamber 6, and finally be discharged from the ventilation port 2. The cooled air can take away more heat and better cool the equipment in the installation chamber 6.
[0033] In the above embodiment, as a preferred solution, a reversing mechanism is provided at the bottom of the ventilation pipe 4, and the reversing mechanism is provided with a first state and a second state. When the reversing mechanism is in the first state, the installation chamber 6 is communicated with the cooling chamber 7 through the ventilation pipe 4, and the air outlet end of the ventilation pipe 4 is closed. When the reversing mechanism is in the second state, the ventilation pipe 4 and the cooling chamber 7 are closed, and the installation chamber 6 is communicated with the outside through the ventilation pipe 4. When the reversing mechanism is in the first state, the ventilation pipe 4 is communicated with the cooling chamber 7. During the reversal of the exhaust fan 5, the outside air is drawn into the cooling chamber 7. When the air passes through the heat sink 8, the heat sink 8 The air is cooled. When the reversing mechanism is in the second state, the ventilation pipe 4 and the cooling chamber 7 are closed, and the exhaust fan 5 rotates forward to directly draw the air in the installation chamber 6 into the ventilation pipe 4, and then directly discharge it to the outside of the cabinet 1 through the ventilation pipe 4. Through the reversing mechanism, when the equipment load is low, the exhaust fan 5 can be used to draw the outside air from the vent 2 into the installation chamber 6 to cool the equipment in the installation chamber 6. When the outside load is high or the outside air temperature is high, the air can be drawn from the cooling chamber 7, cooled by the heat sink 8, and blown into the installation chamber 6 to achieve a stronger cooling effect.
[0034] In the above embodiment, as a preferred solution, the reversing mechanism includes a steering gear 12 and a rotating shaft 13, the rotating shaft 13 is arranged inside the ventilation pipe 4, the steering gear 12 is fixedly connected to the side of the cabinet 1, one end of the rotating shaft 13 is fixedly connected to the output shaft of the steering gear 12, and the rotating shaft 13 fits in the cabinet 1 to play a certain sealing role;
[0035] In the above embodiment, as a preferred solution, the outer surface of the rotating shaft 13 is provided with an air delivery hole 14, the cross-section of the air delivery hole 14 is T-shaped, and the outer side of the rotating shaft 13 is provided with air delivery holes 14 in three directions.

When the ventilation pipe 4 is connected with the cooling bin 7, the cooled air in the cooling bin 7 can enter the ventilation pipe 4. The steering gear cooperates with the exhaust fan to adjust the flow direction of the airflow, and adjust the heat dissipation strategy according to different load conditions. When the load is low, only the exhaust fan is used for heat dissipation to reduce energy consumption. When the load is high, the heat sink is used to dissipate heat from the installation bin, improve the heat dissipation intensity, make the installation bin at a suitable temperature, and at the same time increase the service life of the heat sink;
[0036] In the above embodiment, as a preferred solution, the water delivery pipe 9 includes an inlet pipe 10 and a return pipe 11. The inlet pipe 10 is spirally arranged on the inner wall of the cooling chamber 7. The inlet pipe 10 is connected to the water inlet end of the heat sink 8, and the return pipe 11 is connected to the water outlet end of the heat sink 8. The spiral arrangement of the inlet pipe 10 can increase the contact area with the air and further reduce the temperature of the air flowing through. The cold water source transports the cold water to the inlet pipe 10, and then flows into the heat sink 8 along the inlet pipe 10, so that the heat sink 8 maintains a low temperature. The inlet pipe 10 is connected to the bottom of the heat sink 8, so that the cold water can stay in the heat sink 8 for a long time.

A cover plate 22 is detachably connected to the side of the cabinet 1. The cover plate 22 is used to cover the inspection port 21. When cleaning is performed in subsequent maintenance, the cover plate 22 can be directly opened to clean the ventilation pipe 4, thereby reducing the difficulty of cleaning.
[0040] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
[0041] In the utility model, the working steps of the device are as follows:

Install the equipment in the installation chamber 6. When the load is low, start the exhaust fan 5 to rotate forward, and make the steering gear 12 drive the shaft 13 to rotate, so that the air delivery hole 14 on the shaft 13 connects the ventilation pipe 4 with the bottom exhaust port 17. At this time, the outside air enters the installation chamber 6 from the ventilation port 2 to cool the equipment and then is discharged from the bottom exhaust port 17 at the bottom;
[0043] When the equipment load is high or the outside temperature is high, the exhaust fan 5 is adjusted to reverse, and the steering gear 12 drives the rotating shaft 13 to rotate, so that the cooling chamber 7 is connected with the ventilation pipe 4, and cold water is input into the heat sink 8 from the water inlet pipe 10. At this time, the air passes through the heat sink 8 and is cooled before entering the ventilation pipe 4, and then enters the installation chamber 6 to cool the equipment, and is finally discharged from the vent 2.
