Description

Technical Field

[0001] This utility model relates to capacitor compensation cabinets, specifically to a capacitor compensation cabinet that is protected against heat surge. Background Technology

[0002] The so-called heat surge is the heat generated when the current in the capacitor compensation cabinet passes through the control electronic components. When the heat accumulates and cannot be dissipated, it forms a local high temperature, which is the heat surge. This causes the control electronic components to overheat and increase their resistance.

[0003] The existing capacitor compensation cabinets simply use ventilation holes for heat dissipation. However, this simple design limits its effectiveness. Adding exhaust fans is the most direct solution, but it inevitably causes noise pollution and increases the need for future maintenance, making it uneconomical. Therefore, a better solution is needed to optimize the heat dissipation of the existing design to prevent the damage caused by heat surges. Utility Model Content

[0004] The purpose of this invention is to provide a capacitor compensation cabinet that is protected against heat surge, in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A capacitor compensation cabinet for heat surge protection includes a cabinet, on the top of which are symmetrically fixedly provided with vent slots distributed on adjacent sides, and a flow-blocking baffle is fixedly welded inside the vent slot.

[0007] The flow-blocking baffle and the air outlet slot maintain a predetermined distance to form an airflow channel;

[0008] The sidewall of the flow-blocking baffle is fixedly disposed on a finned plate that is in contact with the top of the box and is arranged in a linear array.

[0009] A C-shaped sheet metal part is fixedly installed between the flow-blocking baffle, the box body and the opposite side walls of the air outlet slot, and multiple finned plates pass through the C-shaped sheet metal part in sequence.

[0010] Preferably, a baffle with an internally fixed silicone grease layer is fixedly installed inside the box.

[0011] The baffle maintains a predetermined distance from the top inner side of the box to form a cavity, while the airflow channel is fixedly connected to the cavity.

[0012] Preferably, the baffle is fixedly provided with a plurality of vertical plates arranged in a linear array and distributed relative to the top of the inner side of the box.

[0013] Preferably, a wire mesh is fixedly installed between the baffle and the bottom of the inner side of the box, and the wire mesh is distributed close to the side wall of the box.

[0014] Preferably, the wire mesh is fixedly provided with a plurality of V-shaped copper plates arranged in a matrix, the top of the V-shaped copper plates extending into the interior of the box, and the ends of the V-shaped copper plates connecting to the inner wall of the box.

[0015] Preferably, the V-shaped copper plate includes two legs, and the two legs have coaxially distributed through holes.

[0016] Preferably, the baffle has an air inlet, the diameter of which is smaller than the diameter of the through hole.

[0017] Preferably, the flow-blocking baffle is divided into a horizontal part, a raised part and a vertical part according to its shape. The horizontal part is located at the port of the air outlet slot, and the raised part is located at the junction of the horizontal part and the vertical part, and is located on the horizontal plane where the horizontal part is located.

[0018] Preferably, both of the air outlet ports are horizontal and distributed relative to each other.

[0019] In the above technical solution, the capacitor compensation cabinet for preventing heat surge provided by this utility model has the following beneficial effects: by adding two symmetrically arranged air outlet slots on the top of the cabinet, and then adding finned plates and C-shaped sheet metal parts to the ports of the air outlet slots to increase the heat dissipation area, a temperature difference is formed between the ports of the air outlet slots and the inside of the cabinet, thereby forming airflow in the temperature difference, thereby achieving heat dissipation.

[0020] Secondly, the flow-blocking baffle added inside the outlet port of the embodiment can prevent external liquid from splashing into the box from the outlet. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-3 As shown, a capacitor compensation cabinet for preventing heat surge includes a cabinet 1. The top of the cabinet 1 is symmetrically and fixedly provided with air outlet slots 2 distributed on adjacent sides. A flow-blocking baffle 3 is fixedly welded inside the air outlet slots 2.

[0029] A predetermined distance is maintained between the flow-blocking baffle 3 and the air outlet slot 2 to form an airflow channel 100;

[0030] The sidewall of the flow-blocking baffle 3 is fixedly installed on the finned plate 31 that is in contact with the top of the housing 1 and is arranged in a linear array;

[0031] A C-shaped sheet metal part 4 is fixedly installed between the flow baffle 3, the box body 1 and the air outlet slot 2 on opposite side walls, and multiple finned plates 31 pass through the C-shaped sheet metal part 4 in sequence.

[0032] Specifically, in this embodiment, both air outlet slots have two ports that are horizontal and relatively distributed, combined with... Figure 1 It can be seen that, secondly, the flow-blocking baffle 3 is divided into a horizontal part 32, a raised part 33 and a vertical part 34 according to its shape. The horizontal part 32 is located at the port of the air outlet 2, and the raised part 33 is located at the junction of the horizontal part 32 and the vertical part 34 and is located on the horizontal plane where the horizontal part 32 is located. It can prevent external liquid from splashing from the air outlet 2 to the box 1.

[0033] In the above technology, by adding two symmetrically arranged air outlet slots 2 to the top of the housing 1, and then adding finned plates 31 and C-shaped sheet metal parts 4 to the ports of the air outlet slots 2 to increase the heat dissipation area, a temperature difference is formed between the ports of the air outlet slots 2 and the interior of the housing 1, thereby forming airflow in the temperature difference, and thus achieving heat dissipation.

[0034] As a further embodiment of this utility model, a baffle 5 with an internally fixed silicone grease layer 51 is fixedly installed inside the housing 1 in the above embodiment. The baffle 5 maintains a predetermined distance from the top inner side of the housing 1 to form a cavity, and the airflow channel 100 is fixedly connected to the cavity.

[0035] Specifically, in the embodiment, the known hot airflow flows upward, and since the airflow channel 100 is fixedly connected to the cavity, the temperature of the cavity must be lower than that inside the box 1. Therefore, the hot airflow will actively approach the baffle 5 and then be absorbed and transferred by the silicone grease interlayer 51.

[0036] As another embodiment of this utility model, a plurality of vertical pieces 52 arranged in a linear array and distributed relative to the top of the inner side of the box 1 are fixedly provided on the baffle 5.

[0037] Specifically, in combination Figure 3 It is understood that the vertical plate 52 in the embodiment is made of aluminum alloy, which is intended to increase the contact area with air, thereby increasing the heat absorption capacity of the baffle 5 and thus optimizing the heat dissipation inside the box 1.

[0038] As a further embodiment of this utility model, a wire mesh 6 is fixedly installed between the baffle 5 and the bottom inner side of the box 1, with the wire mesh 6 distributed close to the side wall of the box 1. Multiple V-shaped copper plates 7 are fixedly installed on the wire mesh 6 in a matrix arrangement, with the top of the V-shaped copper plates 7 extending into the interior of the box 1, and the ends of the V-shaped copper plates 7 connected to the inner wall of the box 1. Furthermore, each V-shaped copper plate 7 includes two legs, with coaxially distributed through holes 71 on the two legs. Additionally, an air inlet 53 is provided on the baffle 5, with the diameter of the air inlet 53 being smaller than the diameter of the through holes 71.

[0039] Specifically, in combination Figure 2 and Figure 3 As can be seen, both the wire mesh 6 and the V-shaped copper plate 7 in the embodiment are good conductors of heat. Therefore, the heat inside the housing 1 will also be absorbed by the wire mesh 6 and the V-shaped copper plate 7. Since the temperature of the cavity is necessarily lower than that inside the housing 1, the upward airflow will also enter through the air inlet 53. When the airflow passes through the air inlet 53, the wire mesh 6 and the V-shaped copper plate 7 will absorb the heat of the passing airflow. This further optimizes the heat dissipation inside the housing 1.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
