[0002] A control cabinet heat dissipation fin refers to a specific structural component designed for control cabinets to improve the heat dissipation effect of internal modules.

[0003] In existing technologies, the heat dissipation fins of control cabinets are often fixed to the module body by permanent connection methods such as welding and riveting. Although welding can ensure the connection strength, once the heat dissipation fins are damaged, it is almost impossible to disassemble and replace them. The module body must be replaced together, resulting in a waste of resources. Riveting also has the problem of difficult disassembly. Forced disassembly will cause irreversible damage to the module body and surrounding components, greatly increasing maintenance costs and time costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that traditional control cabinet heat dissipation fins are often fixed to the module body by permanent connection methods such as welding and riveting, which makes disassembly difficult. Therefore, this utility model proposes a control cabinet heat dissipation fin.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat dissipation fin for a control cabinet, comprising a module body, a fixing device on one side of the module body, the fixing device comprising two snap-fit ​​seats and two snap fasteners, one side of the two snap-fit ​​seats being fixedly connected to the module body, and an L-shaped plate being fixedly connected to the side of the two snap fasteners that are close to each other, two bolts being threadedly connected to one side of the L-shaped plate, a washer being slidably connected to the arc surface of the bolts, and a heat dissipation fin body being threadedly connected to the arc surface of the four bolts.

[0006] The effect achieved by the above components is that after the buckle and the connector are assembled, the L-shaped plate is fixed in position, thus completing the fixation of the heat sink body.

[0007] Preferably, two fixing rods are fixedly connected to one side of the L-shaped plate, and a U-shaped anti-fooling rod is fixedly connected to one end of each fixing rod.

[0008] The aforementioned components achieve the following effect: the U-shaped anti-fooling rod is fixed on the fixed rod, and the fixed rod is fixed on the L-shaped plate.

[0009] Preferably, the arc surfaces of the two U-shaped anti-fooling rods are fixedly connected to a reinforcing plate, and the arc surfaces of the U-shaped anti-fooling rods are slidably connected to an anti-fooling ring.

[0010] The aforementioned components achieve the following effects: the U-shaped anti-fooling rod and the anti-fooling ring are matched, and the reinforcing plate prevents the U-shaped anti-fooling rod from deforming.

[0011] Preferably, the arc surface of the anti-fool ring is fixedly connected to a fixing block, and the side of the two fixing blocks that are close to each other is fixedly connected to the snap-fit ​​seat.

[0012] The above components achieve the following effect: the anti-foolproof ring is fixed on the fixing block, and the fixing block is fixed on the snap-fit ​​seat.

[0013] Preferably, a force-bearing device is provided on one side of the L-shaped plate. The force-bearing device includes two U-shaped plates, the two ends of which are fixedly connected to the L-shaped plate. Two round blocks are fixedly connected to the sides of the two U-shaped plates that are far apart from each other.

[0014] The effect achieved by the above components is that the round block is fixed on the U-shaped plate, and the U-shaped plate is fixed on the L-shaped plate.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this invention, a fixing device is used to replace the heat sink fin body when it is necessary to pull the heat sink fin body. The force is transmitted to the L-shaped plate, causing the buckle to disengage from the buckle seat. The bolts are then removed to replace the heat sink fin body. This fixing device solves the problem that traditional control cabinet heat sink fins are often fixed to the module body by permanent connection methods such as welding and riveting, which makes disassembly difficult. Forced disassembly can cause irreversible damage to the module body and surrounding components, greatly increasing maintenance costs and time costs.

[0025] In this invention, a force-bearing device is used to facilitate the removal of the heat sink fins. When the heat sink fins need to be easily pulled out, the anti-slip sleeve is gripped and a pulling force is applied. The pulling force is transmitted sequentially through the anti-slip sleeve to the force-bearing rod, connecting plate, ring, round block, U-shaped plate, and L-shaped plate, ultimately driving the heat sink fin body to move and achieving convenient disassembly. The force-bearing device solves the problem of traditional control cabinet heat sink fins lacking a point of leverage, which makes disassembly difficult. Attached Figure Description

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: a heat dissipation fin for a control cabinet, including a module body 1, a fixing device 2 on one side of the module body 1, and a force-bearing device 3 on one side of the L-shaped plate 203.

[0032] The following section will explain the specific setup and function of its fixing device 2 and force-bearing device 3.

[0033] Reference Figure 2 and Figure 3As shown in this embodiment: the fixing device 2 includes two snap-fit ​​seats 201 and two snap fasteners 202. One side of the two snap-fit ​​seats 201 is fixedly connected to the module body 1. An L-shaped plate 203 is fixedly connected to the side of each snap fastener 202 that is close to each other. Two bolts 204 are threadedly connected to one side of the L-shaped plate 203. Washers 205 are slidably connected to the arc surface of the bolts 204. The arc surface of the four bolts 204 is threadedly connected to the heat dissipation fin body 206. This achieves the effect of fixing the position of the L-shaped plate 203 and the heat dissipation fin body 206 after the snap fasteners 202 and snap-fit ​​seats 201 are assembled. Two fixing rods 207 are fixedly connected to one side of the L-shaped plate 203. A U-shaped anti-fooling rod 208 is fixedly connected to one end of each fixing rod 207. This achieves the effect of the U-shaped anti-fooling rod 208 being fixed to the fixing rod 207, and the fixing rod 207 being fixed to the L-shaped plate 203. Two U-shaped anti-foolproof rods 208 are fixedly connected to reinforcing plates 211 on their arc surfaces, and anti-foolproof rings 209 are slidably connected to their arc surfaces. This achieves the effect of matching the U-shaped anti-foolproof rods 208 and anti-foolproof rings 209, and the reinforcing plates 211 prevent the U-shaped anti-foolproof rods 208 from deforming. The arc surfaces of the anti-foolproof rings 209 are fixedly connected to fixing blocks 210, and the sides of the two fixing blocks 210 that are close to each other are fixedly connected to the locking seat 201. This achieves the effect of fixing the anti-foolproof rings 209 to the fixing blocks 210, and fixing the fixing blocks 210 to the locking seat 201.

[0034] Reference Figure 4 As shown in this embodiment: the force-bearing device 3 includes two U-shaped plates 31, both ends of which are fixedly connected to an L-shaped plate 203. Two circular blocks 32 are fixedly connected to the sides of the two U-shaped plates 31 that are far apart from each other. This achieves the effect of the circular blocks 32 being fixed to the U-shaped plates 31, and the U-shaped plates 31 being fixed to the L-shaped plate 203. A circular ring 33 is slidably connected to the arc surface of the circular block 32. This achieves the effect of the circular ring 33 and the circular block 32 being compatible. A connecting plate 34 is fixedly connected to the arc surface of the two circular rings 33. This achieves the effect of the connecting plate 34 being fixed to the circular ring 33. A force-bearing rod 35 is fixedly connected to the side of the two connecting plates 34 that is close to each other. This achieves the effect of the force-bearing rod 35 being fixed to the connecting plate 34. An anti-slip sleeve 36, made of rubber, is fixedly connected to the arc surface of the force-bearing rod 35. This achieves the effect of the anti-slip sleeve 36 increasing friction.

[0035] Working principle: When the heat sink fin body 206 needs to be replaced via the fixing device 2, the operator first pulls the heat sink fin body 206, applying force away from the module body 1. This pulling force is transmitted to the latch 202 through the L-shaped plate 203, causing the latch 202 to undergo slight elastic deformation, thus releasing it from the limiting constraint of the latch seat 201. At the same time, the U-shaped anti-fooling rod 208 moves synchronously away from the anti-fooling ring 209, releasing the anti-fooling restriction. Because the thermally conductive adhesive coated on the contact surface between the heat sink fin body 206 and the module body 1 has moderate adhesion, it will not significantly hinder the disassembly operation. After completing the above steps, use a tool to rotate the fixing bolt 204 to unscrew it from the heat sink fin body 206, thus separating the heat sink fin body 206 from the L-shaped plate 203. Finally, install the new heat sink fin body 206 onto the L-shaped plate 203 and complete the assembly in the reverse order. The fixing device 2 solves the problem that traditional control cabinet heat sink fins are often fixed to the module body 1 by permanent connection methods such as welding and riveting, which makes disassembly difficult. Forced disassembly will cause irreversible damage to the module body 1 and surrounding components, greatly increasing maintenance costs and time costs.

[0036] When the heat sink fin body 206 needs to be easily pulled away using the force-bearing device 3, the operator first holds the anti-slip sleeve 36 and then applies a pulling force away from the heat sink fin body 206. This pulling force is transmitted in an orderly manner. First, it is transmitted from the anti-slip sleeve 36 to the force-bearing rod 35, then from the force-bearing rod 35 to the connecting plate 34, and then from the connecting plate 34 to the ring 33. After receiving the pulling force, the ring 33 transmits it to the circular block 32. After receiving the pulling force, the circular block 32 further transmits it to the U-shaped plate. After receiving the pulling force, the U-shaped plate transmits the force to the L-shaped plate. Finally, the L-shaped plate transmits the pulling force to the heat sink fin body 206, thereby causing the heat sink fin body 206 to move and achieve the purpose of easy disassembly. Through the fixing device 2, the problem of difficult disassembly caused by the lack of a force-bearing point for the heat sink fins of traditional control cabinets is solved.
