[0033] The cabinet 1 has a chamber. Specifically, Figure 1-3 As shown, the cabinet body 1 is a rectangular cabinet body 1 extending in the up-down direction.

[0034] The partition plate 2 is disposed in the chamber and divides the chamber into a first chamber 11 and a second chamber 12 which are independent of each other. The first chamber 11 is suitable for installing electrical components and connecting wires. Figure 4 and Figure 5 As shown, the partition plate 2 is a vertical plate extending in the up and down directions. The partition plate 2 is arranged in the chamber and the outer peripheral surface of the partition plate 2 is connected to the inner peripheral surface of the chamber, so that the partition plate 2 divides the chamber into a first chamber 11 and a second chamber 12 arranged in sequence along the left and right directions. Electrical components and connecting wires can be installed in the first chamber 11.

[0035] The first heat dissipation component 3 is disposed in the second cavity 12, and the first heat dissipation component 3 is used to absorb the heat generated by the electrical components and connecting wires in the first cavity 11.

[0036] The second heat dissipation component 4 is disposed in the first cavity 11 and is located on at least one of the top of the first cavity 11 and the bottom of the first cavity 11. The second heat dissipation component 4 is used to dissipate the heat in the first cavity 11. Specifically, Figure 4 and Figure 5 As shown, the second heat dissipation component 4 is arranged in the first cavity 11, and can be arranged at the top of the first cavity 11 and the bottom of the first cavity 11 according to actual conditions. The second heat dissipation component 4 is used to dissipate the heat generated by the electrical components and connecting wires in the first cavity 11, so that the second heat dissipation component 4 cools the electrical components and connecting wires in the first cavity 11.

[0037] The electrical equipment cabinet 100 of the embodiment of the present invention is provided with a partition plate 2, a first heat dissipation component 3 and a second heat dissipation component 4. The first heat dissipation component 3 absorbs the heat generated by the electrical components and the connecting wires, and the second heat dissipation component 4 dissipates the heat generated by the electrical components and the connecting wires.

[0038] In some embodiments, the first heat dissipation assembly 3 includes a refrigeration box 31 and a refrigeration element 32 .

[0039] The refrigeration box 31 is disposed in the second cavity 12 and is suitable for storing a cooling liquid, and the cooling liquid is used to absorb the heat of the first cavity 11 to cool the first cavity 11. Specifically, Figure 5As shown, the refrigeration box 31 is a rectangular water-cooled box and is arranged in the second cavity 12. The coolant is cooling water and is arranged in the refrigeration box 31, so that the coolant cools the first cavity 11 through the refrigeration box 31 to ensure the normal operation of the electrical components and connecting wires.

[0040] The refrigeration element 32 is disposed on the outer peripheral surface of the refrigeration box 31 and is located on a side of the refrigeration box 31 away from the first cavity 11. The refrigeration element 32 is used to cool the coolant in the refrigeration box 31. Specifically, Figure 5 As shown, the cooling element 32 can be a semiconductor cooling sheet, and the cold end of the cooling element 32 is attached to the left side surface of the refrigeration box 31. The cooling element 32 can be connected to an external power supply. Thus, the refrigeration box 31 is cooled by the cooling element 32, thereby ensuring the cooling efficiency of the coolant.

[0041] In some embodiments, the second heat dissipation assembly 4 includes a motor 41 , a first impeller 42 , and a second impeller 43 .

[0042] The motor 41 is arranged outside the first cavity 11 and located at the top of the cabinet 1. Specifically, Figure 4 As shown, the motor 41 is disposed at the upper end of the cabinet 1 and outside the first cavity 11 , and the output shaft of the motor 41 extends into the cabinet 1 .

[0043] The first impeller 42 is disposed in the first chamber 11 and is located at the top of the first chamber 11. The first impeller 42 is connected to the motor 41 so that the motor 41 drives the first impeller 42 to rotate. Figure 4 As shown, the first impeller 42 is disposed in the first cavity 11 and is located above the electrical components and the connecting wires. The first impeller 42 is connected to the output shaft of the motor 41, so that the motor 41 drives the first impeller 42 to rotate, so that the first impeller 42 blows air to the electrical components and the connecting wires to dissipate the heat in the electrical components and the connecting wires.

[0044] The second impeller 43 is disposed in the first chamber 11 and is located at the bottom of the first chamber 11, and the electrical components and connecting wires in the first chamber 11 are located between the first impeller 42 and the second impeller 43, and the second impeller 43 is connected to the motor 41 so that the motor 41 drives the second impeller 43 to rotate. Specifically, Figure 4 As shown, the second impeller 43 is arranged in the first cavity 11 and is located below the device element and the connecting line. The second impeller 43 is connected to the output shaft of the motor 41, so that the motor 41 drives the second impeller 43 to rotate. The second impeller 43 can blow away the heat in the device element and the connecting line, thereby ensuring the heat dissipation efficiency of the second heat dissipation component 4.

[0045] In some embodiments, the second heat dissipation assembly 4 further includes a transmission shaft 44 , a first transmission member 45 and a second transmission member 46 .

[0046] The transmission shaft 44 extends in the up-down direction and is located outside the cabinet 1. Figure 4 As shown, the transmission shaft 44 is a vertical rotating shaft extending in the up-down direction. An installation box 47 is fixedly installed outside the cabinet 1, and the transmission shaft 44 is rotatably arranged in the installation box 47.

[0047] The two ends of the first transmission member 45 are respectively connected to the first impeller 42 and the transmission shaft 44, so that the first impeller 42 drives the transmission shaft 44 to rotate through the first transmission member 45. Figure 4 As shown, the first transmission member 45 includes a first transmission belt 451, a first gear 452 and a second gear 453. The first gear 452 is arranged on the rotating shaft of the first impeller 42 and rotates with the first impeller 42. The second gear 453 is arranged on the upper end of the transmission shaft 44. The first transmission belt 451 is sleeved on the first gear 452 and the second gear 453. Thus, the rotating shaft is driven to rotate by the motor 41, the rotating shaft drives the first gear 452 to rotate, the first gear 452 drives the first transmission belt 451 to rotate, and the first transmission belt 451 drives the transmission shaft 44 to rotate through the second gear 453.

[0048] The two ends of the second transmission member 46 are respectively connected to the transmission shaft 44 and the second impeller 43, so that the transmission shaft 44 drives the second impeller 43 to rotate through the second transmission member 46. Figure 4 As shown, the second transmission member 46 includes a second transmission belt 461, a third gear 462 and a fourth gear 463. The third gear 462 is arranged at the lower end of the transmission shaft 44 and rotates with the transmission shaft 44. The fourth gear 463 is arranged on the rotating shaft of the second impeller 43. The second transmission belt 461 is sleeved on the third gear 462 and the fourth gear 463. The transmission shaft 44 drives the second transmission belt 461 to rotate through the third gear 462. The second transmission belt 461 drives the second impeller 43 to rotate through the fourth gear 463. Therefore, the motor 41 can drive the first impeller 42 and the second impeller 43 to rotate synchronously through the arrangement of the transmission shaft 44, the first transmission member 45 and the second transmission member 46.

[0049] In some embodiments, the first impeller 42 is used to blow air to the electrical components and connecting wires in the first cavity 11, so as to dissipate the heat in the electrical components and connecting wires in the first cavity 11, and the second impeller 43 is used to extract the heat in the first cavity 11, so as to extract the heat in the first cavity 11 out of the first cavity 11. Specifically, the first impeller 42 and the second impeller 43 rotate in the same direction, and the first impeller 42 can blow air to the electrical components and connecting wires, and the second impeller 43 can extract air from the electrical components and connecting wires, so that the electrical components and connecting wires can be quickly cooled down.

[0050] In some embodiments, the first heat dissipation assembly 3 further includes a third impeller 33 and a third transmission member 34 .

[0051] The third impeller 33 is disposed in the second chamber 12 and is located at the top of the second chamber 12. Both ends of the third transmission member 34 are connected to the third impeller 33 and the first impeller 42, respectively, so that the first impeller 42 drives the third impeller 33 to rotate through the third transmission member 34. Specifically, Figure 4 and Figure 5 As shown, the third transmission member 34 includes a fifth gear 341, a sixth gear 342 and a third transmission belt 343. The fifth gear 341 is mounted on the rotating shaft of the first impeller 42 and rotates with the first impeller 42. The sixth gear 342 is mounted on the rotating shaft of the third impeller 33 and can drive the third impeller 33 to rotate. The third transmission belt 343 is sleeved on the fifth gear 341 and the sixth gear 342. Thus, the first impeller 42 drives the third transmission belt 343 to rotate through the fifth gear 341. The third transmission drives the third impeller 33 to rotate through the third transmission belt 343. Thus, air is blown to the second cavity 12, so that the heat in the second cavity 12 is blown out of the second cavity 12, thereby ensuring the heat dissipation efficiency of the first heat dissipation component 3.

[0052] In some embodiments, the electrical equipment cabinet 100 further includes a mounting assembly 5 , which includes a mounting plate 51 , a first mounting bracket 52 , and a second mounting bracket 53 .

[0053] The mounting plate 51 is disposed in the first cavity 11 to divide the first cavity 11 into a first sub-cavity and a second sub-cavity along the vertical direction. The mounting plate 51 is provided with a wiring hole 512 and a first mounting hole 511 that penetrate the mounting plate 51 along the vertical direction. There are multiple wiring holes 512 and multiple first mounting holes 511. The multiple first mounting holes 511 are arranged along the length direction of the mounting plate 51 (such as Figure 1 The left and right directions shown in the figure) are arranged in multiple rows, each row including a plurality of mounting plates 51 along the width direction (such as Figure 1 The first mounting holes 511 are spaced apart in the front-to-back direction (as shown in the figure), and the wiring holes 512 are spaced apart in the width direction of the mounting plate 51 into a first row and a second row. The first row and the second row each include a plurality of wiring holes 512 spaced apart along the length direction of the mounting plate 51, and the plurality of first mounting holes 511 are located between the first wiring holes 512 and the second wiring holes 512.

[0054] Specifically, Figure 5 and Figure 6As shown, the mounting plate 51 is a horizontal plate extending in the left-right direction. The mounting plate 51 is arranged in the first cavity 11, and the outer circumference of the mounting plate 51 is connected to the inner circumference of the first cavity 11, so that the mounting plate 51 divides the first cavity 11 into a first sub-cavity and a second sub-cavity, and the first sub-cavity is located above the second sub-cavity. The mounting plate 51 is provided with a plurality of wiring holes 512 and a plurality of first mounting holes 511 penetrating the mounting plate 51 in the up-down direction. The plurality of first mounting holes 511 are arranged in a plurality of rows at intervals in the left-right direction, and each row includes a plurality of first mounting holes 511 arranged at intervals in the front-to-back direction. The plurality of wiring holes 512 are provided with a first row of wiring holes 512 and a second row of wiring holes 512 arranged at intervals in the front-to-back direction. The first row of wiring holes 512 and the second row of wiring holes 512 both include a plurality of wiring holes 512 arranged at intervals in the left-to-right direction, and the plurality of mounting holes are arranged between the first row of wiring holes 512 and the second row of wiring holes 512. The lines are arranged through the plurality of wiring holes 512, so that the mounting plate 51 is arranged more reasonably.

[0055] The first mounting frame 52 and the second mounting frame 53 are arranged on the mounting plate 51 and spaced apart along the width direction of the mounting plate 51. The lower ends of the first mounting frame 52 and the second mounting frame 53 can be inserted into the first mounting hole 511 so that the first mounting frame 52 and the second mounting frame 53 can be installed on the mounting plate 51 through the first mounting hole 511. The first mounting frame 52 and the second mounting frame 53 are suitable for installing electrical components. Specifically, Figure 5 and Figure 6 As shown, the first mounting frame 52 and the second mounting frame 53 are spaced apart in the front-to-back direction, and the lower end of the first mounting frame 52 and the lower end of the second mounting frame 53 can be inserted into the first mounting hole 511. The positions of the first mounting frame 52 and the second mounting frame 53 inserted into the first mounting hole 511 are adjusted by adjusting the size of the electrical components. The electrical components can be set on the first mounting frame 52 and the second mounting frame 53, so that the electrical components can be installed in the cabinet 1.

[0056] In some embodiments, the first impeller 42 is disposed in the first sub-cavity and located at the top of the first sub-cavity, and the second impeller 43 is disposed in the second sub-cavity and located at the bottom of the second sub-cavity. The first impeller 42 blows the heat energy in the first sub-cavity into the second sub-cavity through the wire hole 512 and the first mounting hole 511, and the second impeller 43 draws the heat energy in the first sub-cavity into the second sub-cavity through the wire hole 512 and the first mounting hole 511, thereby reducing the temperature of the first sub-cavity, preventing the temperature of the electrical components and connecting wires in the first sub-cavity from being too high, and ensuring the service life of the electrical components and connecting wires.

[0057] In some embodiments, the first mounting frame 52 and the second mounting frame 53 both include a first vertical rod 521, a second vertical rod 522 and a cross rod 523. The first vertical rod 521 and the second vertical rod 522 are arranged relative to each other along the length direction of the mounting plate 51. The lower ends of the first vertical rod 521 and the second vertical rod 522 can be inserted into the first mounting hole 511. The first vertical rod 521 and the second vertical rod 522 are both provided with a plurality of second mounting holes 524 arranged at intervals along the up and down directions. Both ends of the cross rod 523 are installed on the first vertical rod 521 and the second vertical rod 522 through the second mounting holes 524.

[0058] Specifically, Figure 6 As shown, the first vertical rod 521 and the second vertical rod 522 are both vertical rods extending in the up-down direction, and the first vertical rod 521 and the second vertical rod 522 are spaced apart in the left-right direction, and the lower ends of the first vertical rod 521 and the second vertical rod 522 can be inserted into the first mounting hole 511, so that the first vertical rod 521 and the second vertical rod 522 are installed on the mounting plate 51, and the first vertical rod 521 and the second vertical rod 522 are both provided with a plurality of second mounting holes 524, and the plurality of second mounting holes 524 are equally spaced apart in the up-down direction, and the two ends of the cross bar 523 are respectively inserted into the second mounting holes 524 of the first vertical rod 521 and the second vertical rod 522 by fasteners, so that the cross bar 523 is installed on the first vertical rod 521 and the second vertical rod 522, and the electrical components are installed on the cross bar 523, and a plurality of second mounting holes 524 are provided, and the height of the cross bar 523 can be adjusted through the plurality of second mounting holes 524 to meet the needs of electrical components of different sizes.

[0059] It is worth mentioning that the first mounting hole 511 can be a threaded hole, and the lower end of the first vertical rod 521 and the lower end of the second vertical rod 522 can be threaded columns, which are threadedly matched with the threaded holes to ensure that the first vertical rod 521 and the second vertical rod 522 are firmly mounted on the mounting plate 51.

[0060] In some embodiments, the partition plate 2 and the mounting plate 51 are both aluminum plates. Specifically, the partition plate 2 and the mounting plate 51 are both made of metal aluminum, which has a high heat absorption coefficient and good heat conduction effect, thereby absorbing the heat in the first sub-cavity.

[0061] In some embodiments, the cabinet 1 is provided with a first vent 13 and a second vent 14 that penetrate the cabinet 1. The first vent 13 is connected to the first cavity 11 and is arranged at the bottom of the cabinet 1. The second vent 14 is connected to the second cavity 12 and extends in the up-down direction. Figure 1-3As shown, filters are provided in the first vent 13 and the second vent 14, and there are two first vents 13. The two first vents 13 are both provided on the rear side of the cabinet 1, and the two first vents 13 are spaced apart in the up-and-down direction, and one vent is located above the mounting plate 51 and communicated with the first sub-cavity, and the other vent is located below the mounting plate 51 and communicated with the second sub-cavity, thereby, the heat in the first sub-cavity and the heat in the second sub-cavity are discharged from the first vent 13, so that the first sub-cavity can be cooled, and the second vent 14 is provided on the rear side of the cabinet 1 and is a rectangular opening extending in the up-and-down direction, and the second vent 14 is communicated with the second cavity 12, thereby, the heat in the second cavity 12 is discharged from the second vent 14.

[0062] In some embodiments, Figure 1-5 As shown, the electrical equipment cabinet 100 further includes a base 6, on which a through hole 61 is provided that penetrates the base 6 in the up-down direction, and the cabinet body 1 is detachably mounted on the base 6, and the through hole 61 is connected to the second sub-cavity. Thus, the heat extracted by the second impeller 43 is discharged outside the cabinet body 1 through the through hole 61.

[0063] The use principle of the electrical equipment cabinet 100 of the embodiment of the present invention: Due to the requirements of the number and size of electrical equipment, the electrical equipment in the electrical equipment cabinet 100 is generally placed in a very crowded manner. This disorderly placement is not conducive to multiple unobstructed air paths from top to bottom in the vacant space of the first cavity 11. Therefore, the position relationship of the first vertical plate and the second vertical plate is determined in a planned manner according to the size and number of the electrical equipment, and the threaded columns at the bottom ends of the first vertical plate and the second vertical plate are screwed into the threaded holes of the first mounting holes 511 for fixation, and then the cross plate is installed in the second mounting holes 524 of the first vertical plate and the second mounting holes 524 of the second vertical plate. Since the side walls of the first vertical plate and the second vertical plate are provided with multiple second mounting holes 524 at equal intervals, the installation height of the cross plate is also adjustable. Reasonable planning of the installation position of the electrical equipment and leaving multiple unobstructed air paths from top to bottom (the first mounting holes 511 and the second mounting holes 524) are more conducive to the heat dissipation of the electrical equipment. The base 6 is installed at the position to be set, and multiple refrigeration components 32 are connected to the external power supply. Since the material used for the partition plate 2 is metal aluminum The metal aluminum has a high heat absorption coefficient and a very good thermal conductivity, and can better absorb the heat in the first cavity 11, so the partition plate 2 can absorb the heat emitted by the electrical equipment in the first cavity 11. Since the cooling ends of the multiple refrigeration components 32 face the outer wall of the refrigeration box 31, the liquid in the refrigeration box 31 is continuously cooled. The cooled liquid continuously absorbs the heat of the partition plate 2, which can indirectly reduce the temperature in the first cavity 11, and the heat generated by the heating ends of the multiple refrigeration components 32 is gathered in the second cavity 12. Turn on the motor 41, The motor 41 drives the first impeller 42, the second impeller 43 and the third impeller 33 to rotate synchronously. Since the wind generated by the rotation of the first impeller 42 is blown into the second sub-cavity from the top of the first sub-cavity, and the wind generated by the rotation of the second impeller 43 draws the heat energy in the first sub-cavity into the second sub-cavity through the first mounting hole 511 and the second mounting hole 524. Since the present invention reasonably arranges the electrical equipment and reserves a plurality of unobstructed wind paths from top to bottom, the heat in the first cavity 11 can be discharged more quickly through the first vent 13 and the second heat dissipation hole.
