A kind of anti-bending sheet metal part

Abstract

This utility model discloses a bending-resistant sheet metal part, belonging to the field of security radiator technology. It solves the problem that the fins on current heat dissipation sheet metal parts are prone to bending and sticking together upon impact, ultimately leading to a decrease in heat dissipation performance. It includes a base plate, two sets of long heat dissipation fins fixedly connected to the base plate, and two connecting strips fixedly connected to the base plate and located between the two sets of long heat dissipation fins. The connecting strips have through holes penetrating the base plate. During transfer, when an external object collides, it will preferentially contact and be guided by the inclined protective fins, making it less likely to impact the long heat dissipation fin sets. During assembly, the side and top retaining strips form a unified structure of fins, jointly resisting external forces, and the reinforcing strips at the connection points of the side heat dissipation fins enhance bending resistance. The side and top retaining strips are made of copper alloy, which allows for heat dissipation even after welding without blocking airflow channels, maintaining good heat dissipation performance.

Description

Technical Field

[0001] This utility model relates to the field of security radiator technology, and in particular to a bending resistant sheet metal part. Background Technology

[0002] Security monitoring is a security system that uses modern technology to monitor and record specific areas in real time. It transmits surveillance footage to a control center via cameras, sensors, and other devices, enabling remote observation and management. Security monitoring not only effectively prevents crimes such as theft and robbery, but also provides timely warnings and on-site recordings in emergencies such as fires and accidents, providing evidence for subsequent investigations.

[0003] Because security monitoring needs to be used 24 hours a day, it generates a relatively large amount of heat during operation. Therefore, it is often necessary to install heat dissipation sheet metal parts to fit the electrical components of the security monitoring system. Otherwise, heat will accumulate and be difficult to dissipate, eventually causing damage to the internal structure of the monitoring system. However, the fins on the current heat dissipation sheet metal parts are relatively easy to bend and stick together when they are hit, which ultimately leads to a decrease in their heat dissipation performance.

[0004] Therefore, a bending-resistant sheet metal part is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bending-resistant sheet metal part.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A bending-resistant sheet metal part includes a base plate, two sets of long heat dissipation fins fixedly connected to the base plate, and two connecting strips fixedly connected to the base plate and located between the two sets of long heat dissipation fins. The connecting strips have connecting through holes that penetrate the base plate. Protective fins located outside the two sets of long heat dissipation fins are fixedly connected to both sides of the base plate. The height of the protective fins is greater than the height of the long heat dissipation fins, and the two protective fins are inclined to one side facing each other.

[0008] Preferably, a plurality of short heat dissipation fins are fixedly connected to the base plate between the two connecting strips, and the height of the short heat dissipation fins is less than or equal to the thickness of the connecting strips.

[0009] Preferably, the long heat dissipation fin assembly includes two side heat dissipation fins and a plurality of intermediate heat dissipation fins located between the two side heat dissipation fins.

[0010] Preferably, a reinforcing strip is fixedly connected between the side heat dissipation fins and the base plate.

[0011] Preferably, the side heat dissipation fins and several intermediate heat dissipation fins in the same long heat dissipation fin group are fixedly connected by side retaining strips and top retaining strips, and the side retaining strips, top retaining strips and the long heat dissipation fin group can be welded together.

[0012] Preferably, the side clips and top clips each include several wide portions, narrow portions fixedly connected between adjacent wide portions, and two clips fixedly connected to each wide portion. The distance between the two clips on the same wide portion gradually increases from one end, and the maximum distance between the two clips on the same wide portion is equal to the width of the side heat dissipation fins and the middle heat dissipation fins.

[0013] Preferably, the side clips and top clips are both made of copper alloy.

[0014] Preferably, the bottom surface of the base plate is fixedly connected with two sliding strips that can form an I-shaped groove.

[0015] This utility model has the following beneficial effects:

[0016] During operation, the protective fins shield and protect the long heat dissipation fin assembly on the base plate. During transfer, any external object colliding with the fins will preferentially contact and be guided by the inclined protective fins, preventing impact on the long heat dissipation fin assembly. During assembly, the side and top retaining strips form a unified structure, jointly resisting external forces, and the reinforcing strips at the joints of the side heat dissipation fins enhance bending resistance. The side and top retaining strips are made of copper alloy, ensuring heat dissipation even after welding without blocking airflow channels, maintaining excellent heat dissipation performance.

[0027] A type of bending resistant sheet metal part, such as Figure 1 and Figure 2As shown, it includes a base plate 1, two sets of long heat dissipation fins fixedly connected to the base plate 1, and two connecting strips 2 fixedly connected to the base plate 1 and located between the two sets of long heat dissipation fins. Two sliding strips 9 that can form an I-shaped groove are fixedly connected to the bottom surface of the base plate 1. A connecting through hole 3 is provided on the connecting strip 2, which penetrates the base plate 1. Protective fins 8 located outside the two sets of long heat dissipation fins are fixedly connected to both sides of the base plate 1. The height of the protective fins 8 is greater than the height of the long heat dissipation fins, and the two protective fins 8 are inclined to one side facing each other.

[0028] A number of short heat dissipation fins 4 are fixedly connected to the base plate 1 between two connecting strips 2. The height of the short heat dissipation fins 4 is less than or equal to the thickness of the connecting strips 2. The long heat dissipation fin group includes two side heat dissipation fins 5 and a number of intermediate heat dissipation fins 6 located between the two side heat dissipation fins 5. A reinforcing strip 7 is fixedly connected between the side heat dissipation fins 5 and the base plate 1.

[0029] The side heat dissipation fins 5 and several intermediate heat dissipation fins 6 in the same long heat dissipation fin group are fixedly connected by side retaining strips 10 and top retaining strips 11. Both side retaining strips 10 and top retaining strips 11 are made of copper alloy. The connection between the side retaining strips 10 and top retaining strips 11 and the long heat dissipation fin group can be welded. Both side retaining strips 10 and top retaining strips 11 include several wide parts 12, narrow parts 13 fixedly connected between adjacent wide parts 12, and two clamping pieces 14 fixedly connected to each wide part 12. The distance between the two clamping pieces 14 on the same wide part 12 gradually increases from one end, and the maximum distance between the two clamping pieces 14 on the same wide part 12 is equal to the width of the side heat dissipation fins 5 and the intermediate heat dissipation fins 6.

[0030] In actual operation, this invention can shield and protect the long heat dissipation fins on the base plate 1 through the protective fins 8. During the actual transfer of this sheet metal part, if an external object collides with it, it will preferentially collide with the protective fins 8. Furthermore, due to the inclined design of the protective fins 8, the external object is guided upon collision, preventing it from easily impacting the long heat dissipation fins. Even during assembly, when the assembler needs to contact the long heat dissipation fins, the side retaining strips 10 and top retaining strips 11 ensure that the side heat dissipation fins 5 and the middle heat dissipation fins 6 in the long heat dissipation fins can form a single unit. When any fin is subjected to force... When deflection deformation is required, the fin can transfer the force to the other fins through the side retaining strip 10 and the top retaining strip 11 to resist the force together. Since the side heat dissipation fin 5 is provided with a reinforcing strip 7 at the connection between it and the base plate 1, the side heat dissipation fin 5 is more difficult to bend, which can further enhance the bending resistance of the entire long heat dissipation fin assembly. At the same time, since the side retaining strip 10 and the top retaining strip 11 are also made of copper alloy, heat dissipation can still be achieved when the side retaining strip 10 and the top retaining strip 11 are welded to the original sheet metal parts. Meanwhile, the air flow channels in the long heat dissipation fin assembly will not be blocked and air can still flow, thus achieving a good heat dissipation effect.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
