Description

Technical Field

[0001] This application relates to the technical field of control cabinets, and in particular to the heat dissipation structure of control cabinets. Background Technology

[0002] The air conditioning control cabinet contains the air conditioning automatic control system. A fan is installed on the cabinet door. When the cabinet door is closed, the electronic components in the automatic control system will generate heat, and the temperature inside the control cabinet will rise. In order to ensure the safe operation of the automatic control system, the fan needs to rotate to exhaust the hot air inside the control cabinet, thereby reducing the temperature inside the control cabinet.

[0003] In the existing technology, when the fan malfunctions, the automatic control system will also stop working in order to protect the system, which directly affects the normal operation of the air conditioner. If there are no maintenance personnel at this time, and because the fan is embedded in the control cabinet door and is inconvenient to disassemble and replace, the temperature in the workshop will be high, which will indirectly affect the work efficiency of the staff. Summary of the Invention

[0004] This application provides a control cabinet heat dissipation structure to solve the heat dissipation problem inside the control cabinet in related technologies.

[0005] Firstly, a heat dissipation structure for the control cabinet is provided, which includes:

[0006] Cabinet door, the cabinet door has a frame, the frame includes:

[0007] The mounting frame is detachably connected to the cabinet door.

[0008] The splicing frame has a mounting groove on the side facing the mounting frame, and the splicing frame and the mounting frame can be detachably connected;

[0009] Dustproof netting is located between the mounting frame and the splicing frame, and the dustproof netting is fitted with the mounting groove.

[0010] The limiting structure includes a telescopic block, which is set on the mounting frame. The telescopic block, dustproof net, and mounting frame form a limiting space for placing the fan.

[0011] In some embodiments, the telescopic block is slidably connected within the mounting frame. The telescopic block has a first position and a second position. When the telescopic block is in the first position, it retracts into the mounting frame. When the telescopic block is in the second position, it extends out of the mounting frame.

[0012] In some embodiments, the limiting structure also includes a spring, with the two ends of the spring connected to the mounting frame and the telescopic block, respectively.

[0013] In some embodiments, the limiting structure further includes a control block;

[0014] The control block is slidably connected to the mounting frame. The sliding direction of the control block is perpendicular to the sliding direction of the telescopic block.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] This application provides a heat dissipation structure for a control cabinet, which can solve the problem of heat dissipation inside the control cabinet in related technologies.

[0029] Please see Figures 1 to 6 The control cabinet heat dissipation structure includes: a cabinet door 1 and a limiting structure 3. The cabinet door 1 is provided with a frame 2, which includes a mounting frame 21, a splicing frame 22, and a dustproof net 24. The mounting frame 21 is detachably connected to the cabinet door 1. The mounting frame 21 has a mounting edge 4 on one side facing the splicing frame 22. The mounting edge 4 is connected to the mounting frame 21 and is close to the cabinet door 1. The splicing frame 22 has a mounting groove 23 on one side facing the mounting frame 21. The splicing frame 22 is connected to the mounting frame 21. The dustproof net 24 is located between the mounting frame 21 and the splicing frame 22. The dustproof net 24 cooperates with the mounting groove 23. The limiting structure 3 includes a telescopic block 31, which is set on the mounting frame 21. The telescopic block 31, the dustproof net 24, and the mounting frame 21 form a limiting space for placing a fan.

[0030] In this embodiment, the cabinet door 1 is hinged to the cabinet body of the control cabinet. A square groove is opened on the cabinet door 1. The mounting frame 21 is a directional frame opposite to the square groove, that is, the mounting frame 21 can be directly inserted into the square groove. When the mounting frame 21 is located in the square groove and the mounting edge 4 is close to the cabinet door 1, the mounting edge 4 and the cabinet door 1 can be fixed by bolts, so that the mounting frame 21 is fixed on the cabinet door 1.

[0031] After the mounting frame 21 is installed, the fan is placed into the mounting frame 21, with one side of the fan pressing against the telescopic block 31. Then, the dustproof net 24 is placed in the mounting groove 23, with the edge of the dustproof net 24 clipped to the edge of the mounting groove 23. The splicing frame 22 is then fixed to the mounting frame 21 with bolts. At this point, the dustproof net 24 is sandwiched between the splicing frame 22 and the mounting frame 21, and the fan is sandwiched between the edge of the dustproof net 24 and the telescopic block 31, thus fixing the fan to the cabinet door 1. When the fan breaks down, the connecting wire at the back of the fan needs to be unplugged first, and then the splicing frame 22 needs to be removed from the mounting frame 21. At this point, the fan can be directly removed and replaced with a good one. Even people who do not know how to repair can quickly replace the fan, avoiding problems that affect the work efficiency of the staff.

[0032] Furthermore, in this embodiment, the telescopic block 31 is slidably connected to the mounting frame 21. The telescopic block 31 has a first position and a second position. When the telescopic block 31 is in the first position, the telescopic block 31 retracts into the mounting frame 21. When the telescopic block 31 is in the second position, the telescopic block 31 extends out of the mounting frame 21. A guide 5 is provided on the side of the mounting frame 21 away from the splicing frame 22. The guide 5 is a frame structure 2, and the inner edge of the guide 5 gradually collapses inward.

[0033] There are two limiting structures 3, which are respectively set opposite to each other on the mounting frame 21. The telescopic block 31 extends and retracts on the mounting frame 21, which can realize the rear installation of the fan. That is, after the mounting frame 21, splicing frame 22 and dustproof net 24 are all installed on the cabinet door 1, the telescopic block 31 is retracted into the mounting frame 21, and the fan enters the mounting frame 21 from the other end of the mounting frame 21 until the fan hits the frame of the dustproof net 24. Then the telescopic block 31 is extended out of the mounting frame 21 so that the telescopic block 31 is in close contact with the fan, thereby fixing the position of the fan. When removing the fan, the fan connection is disconnected first, then the telescopic block 31 can be retracted and then the fan can be removed directly, which is more convenient and faster.

[0034] It should be pointed out that, such as Figure 3 As shown, the inner edge of the guide 5 can guide the fan into the mounting frame 21.

[0035] Furthermore, in this embodiment, the limiting structure 3 also includes a spring 32 and a control block 33, with the two ends of the spring 32 connected to the mounting frame 21 and the telescopic block 31, respectively;

[0036] The control block 33 is slidably connected to the mounting frame 21. The sliding direction of the control block 33 is perpendicular to the sliding direction of the telescopic block 31. The telescopic block 31 has a slot on the side facing the control block 33. The control block 33 can be inserted into the slot. The longitudinal section of the slot gradually increases in size.

[0037] In order to facilitate the control of the position of the telescopic block 31, the position of the telescopic block 31 can be adjusted by controlling the position of the control block 33. That is, the control block 33 is pressed into the mounting frame 21, and the control block 33 will squeeze the edge of the slot, causing the telescopic block 31 to extend out of the mounting frame 21. When the control block 33 moves out of the mounting frame 21, the telescopic block 31 will retract into the mounting frame 21 under the action of gravity.

[0038] It should be noted that the spring 32 will continuously provide a force to the telescopic block 31 to retract into the mounting frame 21. That is, when the control block 33 pushes the telescopic block 31 to extend, the spring 32 will extend. When the force controlling the position of the control block 33 is removed, the spring 32 will pull the telescopic block 31 into the mounting frame 21. During this process, the control block 33 will also be pushed out of the mounting frame 21, which makes operation more convenient.

[0039] Specifically, in this embodiment, the mounting frame 21 is provided with a limiting groove 34, and the end of the control block 33 away from the telescopic block 31 is rotatably connected to a limiting block 35, which can be inserted into the limiting groove 34.

[0040] After the spring 32 is installed, there is a situation where the telescopic block 31 will return to its original position once the control block 33 is not controlled. Therefore, when the control block 33 presses the telescopic block 31 to extend, the rotatable limiting block 35 can be inserted into the limiting groove 34, and the positions of the control block 33 and the telescopic block 31 are fixed by the limiting groove 34 and the limiting block 35.

[0041] The working principle of this application is as follows:

[0042] When the fan is damaged, the staff can directly replace it in this application. When the cabinet door is closed, the staff can take out the fan by disassembling the splicing frame 22 and the dustproof net 24. It should be noted that after the fan is taken out a certain distance, the fan connection cable needs to be unplugged. If the staff can open the cabinet door, they can directly rotate the limiting block 35. Under the action of the spring 32, the telescopic block 31 retracts back into the mounting frame 21. At this time, the staff only needs to unplug the fan connection cable to take out the fan.
