DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 5 , an energy-saving cooling device for an electrical automatic control cabinet, comprising:

[0025] A mounting frame 2 is fixedly installed inside the fixed housing 1, an electronic device 4 is fixedly placed on the mounting frame 2, and a cooling water tank 3 is fixedly installed inside the fixed housing 1. The cooling water tank 3 is installed below the mounting frame 2 to protect and dissipate heat for the electronic device 4;

[0026] The heat dissipation structure includes a protective shell 5 fixedly connected to the side wall of the fixed shell 1, a connecting opening 14 is opened between the protective shell 5 and the fixed shell 1, and the connecting opening 14 penetrates the inner walls of the protective shell 5 and the fixed shell 1, a second heat dissipation plate 17 is fixedly installed inside the protective shell 5, a first heat dissipation plate 7 is fixedly installed at the rear end of each electronic device 4, and the first heat dissipation plate 7 is closely attached to the corresponding electronic device 4, the first heat dissipation plate 7, the second heat dissipation plate 17, and the cooling water tank 3 are interconnected by a water pipe 8, and a second heat dissipation structure is installed inside the protective shell 5;

[0027] The coolant in the cooling water tank 3 circulates between the first heat sink 7, the second heat sink 17 and the cooling water tank 3 through the water pipe 8, taking away the heat of the electronic device 4 during operation, cooling and dissipating it, and at the same time, the second heat dissipation structure dissipates the coolant to prevent the coolant temperature from being too high;

[0028] The second heat dissipation structure includes a motor 9 fixedly mounted on the inner wall of the protective housing 5, the output end of the motor 9 is fixedly connected to a rotating rod 10, a heat dissipation fan 13 is fixedly sleeved on the rotating rod 10, a heat dissipation housing 12 is sleeved on the outer side of the heat dissipation fan 13, and the heat dissipation housing 12 is fixedly connected to the inner wall of the protective housing 5, the heat dissipation housing 12 is fixedly connected to the second heat dissipation plate 17, and a heat pipe is fixedly mounted at the connection between the heat dissipation housing 12 and the second heat dissipation plate 17, and the heat pipe can perform heat exchange more efficiently;

[0029] After the motor 9 is started, its output end drives the rotating rod 10 to rotate, and when the rotating rod 10 rotates, it drives the cooling fan 13 to rotate together. When the cooling fan 13 rotates, wind is generated, and the cooling liquid in the second heat sink 17 is cooled by the heat pipe;

[0030] A protective structure is fixedly installed inside the fixed housing 1, and the protective structure includes a connecting block 15 fixedly installed on the inner wall of the fixed housing 1, a connecting shaft 16 is rotatably connected between the connecting blocks 15, the position of the connecting shaft 16 corresponds to the connecting port 14, and the connecting shaft 16 and the rotating rod 10 are connected by a belt transmission assembly 18. A fixed shaft 19 is rotatably connected to the inner wall of the fixed housing 1, a fixed fan 20 is fixedly sleeved on the fixed shaft 19, and the fixed fan 20 is installed toward the first heat sink 7, a fixed worm 22 is fixedly sleeved on the connecting shaft 16, and a fixed worm wheel 21 corresponding to the fixed worm 22 is fixedly sleeved on the fixed shaft 19, and the fixed worm wheel 21 is meshed with the fixed worm 22;

[0031] When the rotating rod 10 rotates, the connecting shaft 16 rotates accordingly under the action of the belt transmission assembly 18. When the connecting shaft 16 rotates, it drives the fixed worm 22 to rotate together. When the fixed worm 22 rotates, it causes the fixed worm wheel 21 meshing with it to rotate, so that the fixed shaft 19 fixedly connected to the fixed worm wheel 21 rotates, and the fixed fan 20 fixedly installed on the fixed shaft 19 also rotates. When the fixed fan 20 rotates, the wind in the field away from the mounting frame 2 is blown away. Therefore, when there is a coolant leak, the wind generated by the fixed fan 20 will move the coolant in the direction away from the mounting frame 2, that is, the coolant is not easy to come into contact with the electronic device 4, thereby protecting the electronic device 4 and preventing it from being corroded by the coolant;

[0032] A filter screen 6 is fixedly mounted on one side wall of the protective shell 5, an air outlet is opened on the inner wall of the protective shell 5, a rotating rod 10 passes through the filter screen 6 and extends to the outside of the protective shell 5, a fixed scraper 11 is fixedly mounted on one end of the rotating rod 10 located outside the protective shell 5, and the fixed scraper 11 is in close contact with the side wall of the filter screen 6;

[0033] The wind generated by the cooling fan 13 enters the protective housing 5 from the filter 6 and is then discharged from the air outlet. When the air enters the protective housing 5, the filter 6 will filter the air to prevent dust from entering the protective housing 1 and affecting the cooling work of the cooling fan 13. At the same time, when the rotating rod 10 rotates, it will drive the fixed scraper 11 to rotate together. When the fixed scraper 11 rotates, it will scrape the filter 6 to ensure that the filter 6 is clean and prevent the filter 6 from being blocked.

[0034] The motor 9 adopts a variable frequency motor, and a controller matching the motor 9 is fixedly installed inside the fixed housing 1. The controller and the motor 9 are matching existing technologies, so the working principle thereof is not described in detail. The controller can automatically adjust the motor 9 according to the temperature inside the fixed housing 1.

[0035] The connection between the first heat sink 7, the cooling water tank 3, the second heat sink 17 and the water pipe 8 is fixedly installed with a sealing gasket, which has a sealing effect to prevent liquid leakage;

[0036] The side wall of the fixed shell 1 is rotatably connected to a cabinet door through a rotating shaft. A lighting lamp is fixedly installed on the cabinet door. After the cabinet door is opened, the lighting lamp can illuminate. A driving pump is installed in the cooling water tank 3. The driving pump is an existing equipment and is used to drive the coolant in the cooling water tank 3 to flow.

[0037] In the present invention, when the device is in use, the electronic device 4 is running, and the electronic device 4 generates heat during the operation. Then the motor 9 and the driving pump are started, and the driving pump drives the coolant in the cooling water tank 3 to flow. The coolant in the cooling water tank 3 circulates between the first heat sink 7 and the second heat sink 17 and the cooling water tank 3 through the water pipe 8, takes away the heat of the electronic device 4 during the operation, and cools and dissipates the heat. At the same time, the motor 9 is started. After the motor 9 is started, its output end drives the rotating rod 10 to rotate. When the rotating rod 10 rotates, it drives the cooling fan 13 to rotate together. When the cooling fan 13 rotates, it generates wind, and cooperates with the heat pipe to dissipate the coolant in the second heat sink 17 to avoid the temperature of the coolant being too high. Moreover, when the rotating rod 10 rotates, under the action of the belt transmission assembly 18, the connecting shaft 16 rotates accordingly. When the connecting shaft 16 rotates, it drives the fixed worm 22 to rotate together. When the fixed worm 22 rotates, it causes the fixed worm 22 meshing with it to rotate. The fixed worm gear 21 rotates, causing the fixed shaft 19 fixedly connected to the fixed worm gear 21 to rotate, and the fixed fan 20 fixedly installed on the fixed shaft 19 also rotates. When the fixed fan 20 rotates, the wind in the field will be away from the mounting frame 2. Therefore, when there is a coolant leak, the wind generated by the fixed fan 20 will cause the coolant to move in the direction away from the mounting frame 2, that is, the coolant is not easy to come into contact with the electronic device 4, thereby protecting the electronic device 4 and preventing it from being corroded by the coolant. In addition, the wind generated by the cooling fan 13 enters the protective shell 5 from the filter 6 and is then discharged from the air outlet. When the air enters the protective shell 5, the filter 6 will filter the air too much to prevent dust from entering the protective shell 1 and affecting the heat dissipation work of the cooling fan 13. At the same time, when the rotating rod 10 rotates, it will drive the fixed scraper 11 to rotate together. When the fixed scraper 11 rotates, it will scrape the filter 6 to ensure that the filter 6 is clean and prevent the filter 6 from being blocked.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
