Description

Technical Field

[0001] This application relates to the technical field of aluminum substrates, and specifically to an anti-corrosion aluminum substrate. Background Art

[0002] An aluminum substrate is a substrate material mainly composed of aluminum, and is usually used in the manufacture of electronic products, automotive parts, building materials, etc. The aluminum substrate has good thermal conductivity, electrical conductivity and mechanical properties, and also has good corrosion resistance and wear resistance.

[0003] Since the aluminum substrate is entirely made of aluminum material, the conventional anti-corrosion method for the aluminum substrate is to block the surface of the aluminum substrate by coating an anti-corrosion layer, so that the aluminum substrate is less affected by environmental corrosion. Since the aluminum substrate is often used as the base material of an LED lamp, the aluminum substrate is often in a heated state, and high temperature will accelerate the oxidation reaction and other chemical reactions, resulting in damage or destruction of the oxide film on the surface of the aluminum substrate, making it exposed to air or other corrosive media, accelerating the occurrence of corrosion, and limiting the service life of the aluminum substrate.

[0004] In view of the above problems, an anti-corrosion aluminum substrate is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, this application provides an anti-corrosion aluminum substrate, which has the advantages of rapid heat dissipation and reduction of oxidation reaction of the aluminum substrate caused by high temperature.

[0006] To achieve the above object, this application provides the following technical solution: An anti-corrosion aluminum substrate includes a partition and a flat plate fixedly connected vertically. The partition is fixed in the middle position of the flat plate. A sealing plate is also fixedly installed on the side of the partition away from the flat plate. A flow guiding structure for guiding gas is arranged on the partition.

[0007] The flow guiding structure includes top covers fixedly installed at the tops of both sides of the partition and a flow guiding plate fixedly installed in the middle of the partition.

[0008] Further, there are several sealing plates, and several sealing plates are also symmetrically divided into two parts by the partition.

[0009] Further, the flow guiding plate is arc-shaped, and its outer arc surface faces away from the side of the flat plate, and one end of the flow guiding plate extends to the front of the partition.

[0010] Further, a shielding plate also used for closing is integrally connected to the end of the top cover facing the sealing plate, and the end of the top cover facing the flat plate is bent in an arc shape.

[0011] Furthermore, extension plates for increasing the contact area of the partition are fixedly installed at both ends of the partition, and the extension plates are arranged in a vertically offset manner outside the partition.

[0012] Furthermore, connecting pipes for connection are fixedly installed at the upper and lower ends of the partition, and threaded rods for pre-tightening are installed in a threaded manner between adjacent connecting pipes.

[0013] Furthermore, threaded pipes for connection are rotatably installed at both ends of the connecting pipe, and the threaded pipes are threadedly connected to the threaded rods.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] This corrosion-resistant aluminum substrate is composed of a partition and a flat plate connected vertically, and the other side of the partition is surrounded by a sealing plate and a shielding plate to form a hollow space, so that the air flow can be facilitated to flow towards the space between the partition and the flat plate. Further, the contact surface of the partition is increased by the extension plate, so that the partition and the flat plate can dissipate heat quickly under the contact of the air flow. At this time, the temperature rise of the substrate is reduced, which helps to maintain the anti-corrosion layer on the surface of the substrate, reduces the chemical reaction and accelerates the consumption of the anti-corrosion layer, and improves the service life of the aluminum substrate.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0022] Please refer to Figures 1-4, an anti-corrosion aluminum substrate in this embodiment includes a partition plate 1 and a flat plate 2 that are vertically fixedly connected. The partition plate 1 is fixed in the middle position of the flat plate 2, so that the flat plate 2 is divided into two identical intervals by the partition plate 1.

[0023] In this embodiment, a sealing plate 5 is also fixedly installed on the side of the partition plate 1 away from the flat plate 2. Among them, there are several sealing plates 5, and several sealing plates 5 are also symmetrically divided into two parts by the partition plate 1. A hollow space is formed by the flat plate 2 and the sealing plate 5 on both sides of the partition plate 1, so as to facilitate the air to flow through the partition plate 1.

[0024] It should be noted that a flow guiding structure for guiding gas is provided on the partition plate 1. The flow guiding structure includes a top cover 3 fixedly installed at the tops of both sides of the partition plate 1 and a flow guiding plate 7 fixedly installed in the middle of the partition plate 1. Among them, the flow guiding plate 7 is arc-shaped and its outer arc surface faces the side away from the flat plate 2, and one end of the flow guiding plate 7 extends to the front of the partition plate 1.

[0025] With such a design, an opening is provided between the flow guiding plate 7 and the flat plate 2 for gas to enter, so as to improve the drainage efficiency.

[0026] In this embodiment, the end of the top cover 3 facing the flat plate 2 is bent in an arc shape. Since the sides of the top cover 3 and the flow guiding plate 7 close to each other are arc-shaped, the obstruction to the air flow can be reduced.

[0027] In this embodiment, a shielding plate 4 which is also used for closing is integrally connected to the end of the top cover 3 facing the sealing plate 5.

[0028] It should be noted that extension plates 8 for increasing the contact area of the partition plate 1 are fixedly installed at both ends of the partition plate 1. The extension plates 8 are arranged up and down in a staggered manner outside the partition plate 1. The direction of the air flow is guided by the extension plates 8, so that the partition plate 1 can achieve rapid and uniform heat dissipation.

[0029] In order to facilitate the connection of multiple aluminum substrates, connection pipes 6 for connection are fixedly installed at the upper and lower ends of the partition plate 1 in this embodiment, and threaded rods 10 for pre-tightening are threadedly installed between adjacent connection pipes 6.

[0030] Preferably, threaded pipes 9 for connection are rotatably installed at both ends of the connection pipe 6, and the threaded pipes 9 are threadedly connected to the threaded rods 10.

[0031] In specific implementation, the threaded rod 10 and the corresponding connection pipe 6 can be connected to each other by rotating the threaded pipe 9.

[0032] The working principle of the above embodiment is:

[0033] The aluminum substrate is installed with LED lamp bead components on the surface of the flat plate 2 by soldering. During use, gas can enter the space surrounded by the flat plate 2 and the partition plate 1 through the gap of the sealing plate 5 on the opposite side of the flat plate 2, enabling the aluminum flat plate 2 and the partition plate 1 to quickly relieve air flow over a large area, thereby improving the heat dissipation efficiency of the aluminum substrate. At this time, the temperature of the aluminum substrate drops significantly, and the rapid oxidation effect weakens compared to the high-temperature state.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0035] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
