[0036] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 11 The present application will be described in further detail.

[0037] The present application discloses a heat dissipation structure of an industrial control equipment.

[0038] The heat dissipation structure of the industrial control equipment comprises a control cabinet, an air duct 10, a fan 20, an air door mechanism 30 and a partition 40.

[0039] Reference will be made to Figures 1 to 5 The control cabinet comprises a cabinet body 60 and a cabinet door 70, and the cabinet door 70 is connected with the cabinet body 60. The cabinet body 60 is provided with a support 61, and the support 61 is provided with a plurality of groups of mounting positions for mounting the industrial control equipment 80 respectively. The air duct 10 is detachably arranged in the cabinet body 60, more specifically, the air duct 10 is detachably connected with the inner wall of the cabinet body 60 through the stud 63 fixedly arranged on the inner wall of the cabinet body 60 and the nut 64 screwed on the stud 63, and the third sealing gasket 65 is arranged between the air duct 10 and the inner wall of the cabinet body 60.

[0040] The air duct 10 is provided with a plurality of air outlets 11 corresponding to the mounting positions respectively, and the cabinet door 70 is provided with a plurality of heat dissipation openings 71 corresponding to the air outlets 11. The fan 20 is detachably arranged outside the cabinet 60 and connected with the air duct 10. More specifically, the cabinet 60 is provided with an air inlet cover 62 communicating with the air duct 10, and the fan 20 can be a centrifugal fan. The air outlet nozzle 21 of the fan 20 is detachably inserted into the air inlet cover 62.

[0041] When the industrial control equipment 80 is working, it is fixedly arranged at the mounting positions of the support 61, and one industrial control equipment 80 can be arranged at each mounting position. When the industrial control equipment 80 needs to be cooled, the air outside the cabinet 60 is transported into the air duct 10 through the air inlet cover 62 by the fan 20, and then blown out from the air outlets 11 to cool the industrial control equipment 80 at the mounting positions. The cooled air is discharged from the cabinet 60 through the heat dissipation openings 71 of the cabinet door 70.

[0042] With reference to Figures 4 to 8 , the air door mechanism 30 includes a control assembly and an air plate 31. The air plate 31 is arranged on the air duct 10, and the control assembly is arranged on the air duct 10 and connected with the air plate 31. The control assembly is used to drive the air plate 31 to open and close the air outlets 11. The air plate 31 is provided with a first sealing gasket 35 used to seal the air outlets 11 when the air plate 31 closes the air outlets 11.

[0043] When the industrial control equipment 80 is arranged at the mounting positions of the support 61, the air plate 31 is driven to open by the control assembly, so that the air flow in the air duct 10 can be blown out from the air outlets 11. When no industrial control equipment 80 is arranged at a mounting position, the air plate 31 corresponding to the mounting position is driven to close by the control assembly, so that the air flow in the air duct 10 is concentrated to be blown out from the air outlet 11 corresponding to the mounting position where the industrial control equipment 80 is arranged, thereby avoiding air flow loss and improving cooling efficiency.

[0044] In an optional embodiment, the specific structure of the control assembly and the specific connection relationship with the air plate 31 are as follows: the control assembly includes a first elastic member and a locking member. The inner wall of the air duct 10 is provided with a guide column 12, and the air plate 31 is slidingly arranged on the guide column 12 in the air duct 10. The first elastic member acts on the air plate 31 and is used to drive the air plate 31 to open from the air outlets 11. More specifically, the first elastic member is a first spring 32. The air duct 10 is provided with an avoiding groove 13, and the air plate 31 is provided with a pull rod 311. The pull rod 311 is arranged in the avoiding groove 13, and the pull rod 311 is provided with a baffle 313 located in the avoiding groove 13. The first spring 32 is sleeved outside the pull rod 311, and the two ends of the first spring 32 respectively abut against the baffle 313 and the inner end face of the avoiding groove 13.

[0045] The locking element can act on the air deflector 31 and is used to fix the air deflector 31 when it is blocked at the air outlet 11.

[0046] Furthermore, the second elastic element can be a second spring 34. The specific connection relationship between the locking tongue 33, the second elastic element and the air duct 10 is as follows: the air duct 10 is provided with a guide groove 14, the locking tongue 33 is provided in the guide groove 14, the locking tongue 33 is provided with a rod 331, the rod 331 passes through the guide groove 14, the second spring 34 is sleeved on the outside of the rod 331, and the two ends of the second spring 34 abut against the inner end face of the locking tongue 33 and the guide groove 14 respectively.

[0047] When the latch 33 engages with the lock groove 312, the first spring 32 is compressed, and the air deflector 31 blocks the air outlet 11. At this time, pulling the rod 331 causes the latch 33 to disengage from the lock groove 312. Then, under the elastic force of the first spring 32, the air deflector 31 is pushed to move, opening the air outlet 11 and allowing the airflow in the duct 10 to be blown out from the air outlet 11.

[0048] Reference Figure 5 , Figures 9 to 11 The partition 40 is closable at the connection between the air duct 10 and the air inlet hood 62. When the air outlet 21 of the fan 20 is connected to the air inlet hood 62, the partition 40 opens from the connection between the air duct 10 and the air inlet hood 62, allowing the fan 20 to deliver air from outside the cabinet 60 into the air duct 10 through the air inlet hood 62. When the fan 20 needs to be removed from the cabinet 60 for maintenance, dust removal, or cleaning, the fan 20 is first disassembled from the cabinet 60, and then the air outlet 21 of the fan 20 is separated from the air inlet hood 62. When the air outlet 21 of the fan 20 is separated from the air inlet hood 62, the partition 40 can be driven by the linkage component 50 to block the connection between the air duct 10 and the air inlet hood 62, thereby isolating the external environment from the air duct 10 through the partition 40 and preventing dust and other debris from the external environment from entering the air duct 10 through the air inlet hood 62.

[0049] In an alternative embodiment, the specific structure of the linkage assembly 50 and the specific connection relationship with the air outlet 21 and the partition plate 40 are as follows: the linkage assembly 50 comprises a rotating shaft 51 and a worm 52, the rotating shaft 51 is arranged on the air inlet cover 62, and the partition plate 40 is arranged in the air inlet cover 62; the partition plate 40 is provided with a limiting column 42 which is slidably arranged in the air inlet cover 62; the partition plate 40 is provided with a second sealing gasket 43 which is used to seal the communication between the air duct 10 and the air inlet cover 62; the partition plate 40 is provided with a column body 44 which is slidably arranged in the air inlet cover 62; the column body 44 is provided with a rack 41; the rotating shaft 51 is provided with a driven gear 511 which is engaged with the rack 41 and a worm wheel 512 which is engaged with the worm 52; the worm 52 is provided with a driving gear 521; and the air outlet 21 of the fan 20 is provided with a gear row 211 which is capable of being engaged with the driving gear 521.

[0050] When the air outlet 21 of the fan 20 is in the plugged state with the air inlet cover 62, the partition plate 40 is in the open state; at this time, the air outlet 21 of the fan 20 is pulled outward to separate from the air inlet cover 62; in this process, the gear row 211 is engaged with the driving gear 521, and the driving gear 521 is driven to rotate, and then the worm 52 is driven by the driving gear 521, and then the worm wheel 512, the rotating shaft 51 and the driven gear 511 are driven to rotate by the worm 52, and then the rack 41, the column body 44 and the partition plate 40 are driven to move by the driven gear 511; when the gear row 211 is separated from the driving gear 521, the partition plate 40 is just sealed at the communication between the air duct 10 and the air inlet cover 62, so as to isolate the external environment from the air duct 10. Conversely, when the air outlet 21 of the fan 20 is inserted into the air inlet cover 62, the gear row 211 is engaged with the driving gear 521, and then the partition plate 40 is switched from the sealing state to the open state by the worm 52, the worm wheel 512, the driven gear 511 and the rack 41.
