Description

Technical Field

[0001] The invention relates to the technical field of aluminum substrates, in particular to an installation structure of a high thermal conductivity single-sided aluminum substrate. Background Art

[0002] Aluminum substrate is a substrate used for heat dissipation of electronic components, usually made of aluminum alloy. Its main function is to fix electronic components (such as LED lamp beads, integrated circuits, etc.) on it, and transfer the heat generated by the components to the heat dissipation structure through the thermal conductivity of the aluminum substrate itself, thereby achieving heat dissipation. Aluminum substrate has the advantages of good thermal conductivity, light weight, and low cost, so it is widely used in the field of heat dissipation of electronic components.

[0003] To this end, someone has designed an aluminum substrate mounting structure for LED light sources (publication number CN221005001U), including: an aluminum substrate mounting seat, the bottom of which is provided with a heat dissipation structure for heat dissipation; an aluminum substrate, which is fixed to the mounting cavity of the aluminum substrate mounting seat and is in contact with the heat dissipation structure; lamp beads are arranged in an array on the aluminum substrate; a fixing seat, which is hollow inside and is divided into a fixing cavity and an auxiliary heat dissipation cavity by a dividing strip. The utility model can effectively reduce the temperature of LED lamp beads through the combination of the heat dissipation structure, the auxiliary heat dissipation cavity and the heat dissipation fan, thereby improving the life and stability of the LED lamp beads.

[0004] However, although it can effectively conduct and dissipate the heat generated during the operation of the components to achieve a cooling effect, it is inconvenient to operate when installing and fixing the aluminum substrate, which makes the installation of the aluminum substrate lack of certain guidance and limitation, resulting in the need for continuous adjustment during the installation process, and the efficiency is relatively low. In addition, the effect of heat dissipation for the components is relatively simple and common. Therefore, the inventors have designed an installation structure of a high thermal conductivity single-sided aluminum substrate that can effectively improve the thermal conductivity of the aluminum substrate and facilitate the guided installation of the aluminum substrate, which is a common goal pursued by technical personnel in this field.

[0024] Beneficial Effects

[0025] Compared with the prior art, the present invention provides a mounting structure for a high thermal conductivity single-sided aluminum substrate, which has the following beneficial effects:

[0026] 1. The present invention is provided with a limiting component. When the aluminum substrate is connected and installed, the aluminum substrate connected and installed with the component can be aligned with the mounting plate. Then, in the process of downward connection, the limiting part arranged obliquely can guide and limit the aluminum substrate to a certain extent. Moreover, due to the inclined surface of the structure, it can promote its own movement during the connection process of the aluminum substrate, thereby compressing the elastic member 1 and the telescopic rod 1. Then, after being fully connected to the mounting plate, the limiting part can be restored to the initial position to fix the aluminum substrate to form a self-locking, which is easy to operate and convenient for the subsequent connection of bolts and other components. Moreover, under the action of the limiting part and the aluminum substrate being pressed against each other, the loosening of the aluminum substrate can be reduced.

[0027] 2. The present invention is provided with a refrigeration component. After the aluminum substrate is installed, in order to effectively dissipate the heat of the components, the motor can be started so that the motor can drive the cam to rotate through the driving shaft after it works. After the cam rotates, it can cause a certain push on the elastic airbag, so that the elastic airbag will be deformed after being stressed to compress the air inside it. At this time, the air can be turned into low-temperature air under the action of the refrigeration component to blow toward the aluminum substrate. With the rotation of the cam and the eccentric setting of the elastic airbag, the elastic airbag can also restore to its original shape after being stressed, so as to continuously generate low-temperature air blowing toward the aluminum substrate, and the telescopic rod 2 and the elastic member 2 inside it are to further ensure that the elastic airbag can be restored;

[0028] 3. The present invention cooperates with positioning holes, heat-conducting parts and conduction holes. When the aluminum substrate is subjected to heat conduction and cooling treatment, since the heat-conducting parts are installed inside the mounting plate, the heat at the position of the aluminum substrate can be conducted to the back of the mounting plate through the conduction holes again, so as to avoid the aluminum substrate and the mounting plate being closely fitted, which makes it difficult to conduct and dissipate the heat. The heat of the surface components can form a passage to be guided and dissipated under the action of the aluminum substrate, the heat-conducting parts and the conduction holes, thereby improving the heat dissipation efficiency. Moreover, under the action of the conically arranged positioning holes, the heat can also be guided to a certain extent and gathered at the position of the heat-conducting parts, thereby improving the use effect.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example: See Figure 1-5The embodiment of the present invention provides a technical solution: a mounting structure of a high thermal conductivity single-sided aluminum substrate, comprising: a mounting plate 1, as a mounting structure main body, used to fix and support other components; a substrate 2, which is connected to the inner side of the mounting plate 1 and is provided with fixing holes 201 for connecting with the mounting plate 1 around the surface; a heat conduction component, which is installed inside the mounting plate 1 and located below the substrate 2, and is used to conduct the heat of the substrate 2 to the back of the mounting plate 1; a limiting component, which is installed around the surface of the mounting plate 1 and can move in the horizontal direction, and is used to guide and limit the substrate 2; a refrigeration component, which is installed inside the mounting plate 1 and located below the substrate 2, and is used to refrigerate the substrate 2.

[0037] By adopting the above-mentioned embodiment, the mounting plate 1 serves as the main body of the mounting structure, providing a stable foundation for fixing and supporting the substrate 2 and other related components. The heat conducting component improves the heat conduction efficiency and helps to maintain the working temperature of the substrate 2 within an appropriate range. The addition of the refrigeration component not only enhances the heat dissipation effect, but also can actively cool the substrate 2 to ensure that it can maintain a low temperature even when working under high load, thereby improving its performance and stability. The limiting component not only helps to ensure the accuracy of the substrate 2 during the installation process, but also can prevent it from being displaced due to vibration or external force to a certain extent. By cleverly integrating the heat conducting component, the refrigeration component and the limiting component into the mounting structure, not only the heat dissipation efficiency is improved, but also the overall performance and reliability of the mounting structure are enhanced.

[0038] like Figure 2 and Figure 4 As shown, in this embodiment, in order to further perform better heat conduction treatment on the aluminum substrate, the heat conducting component includes a positioning hole 102 opened on the surface of the mounting plate 1 and arranged in a cone shape, and a heat conducting member 4 capable of contacting the substrate 2 is installed on the inner side of the positioning hole 102. The back of the mounting plate 1 is provided with conduction holes 103 which are all connected to the positioning hole 102 and are located below the heat conducting member 4. Through this embodiment, the conical design not only facilitates the installation and positioning of the heat conducting member 4, but also can increase the heat conducting area to a certain extent, thereby improving the heat conduction efficiency. The heat conducting member 4 is usually made of materials with excellent thermal conductivity, such as copper, aluminum or thermally conductive silicone, etc. These materials can effectively conduct the heat generated on the substrate 2 to the mounting plate 1, and the heat can be conducted from the substrate 2 to the mounting plate 1 through the heat conducting member 4, and further dissipated to the back of the mounting plate through the conduction holes 103, so as to improve the heat conduction effect.

[0039] like Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the limiting component includes a slide groove 301 opened around the surface of the mounting plate 1, and a telescopic rod 304 and an elastic member 305 located on the outside of the telescopic rod 304 are installed on the inner side of the slide groove 301, and a limiting portion 3 with a horizontal height higher than the horizontal height of the mounting plate 1 is installed at one end of the telescopic rod 304. Through this embodiment, the slide groove 301 provides a mounting and sliding track for the telescopic rod 304 and the elastic member 305, so that they can be stored and moved into the slide groove 301 when guiding the installation of the aluminum substrate to reduce interference, and the telescopic rod 304 is used to stabilize the elastic member 305 to prevent the limiting portion 3 from shaking due to the action of the elastic member 305 when moving, thereby improving stability, so that when the aluminum substrate is installed, the limiting portion 3 can compress the elastic member 305 and the telescopic rod 304, and after the aluminum substrate is fully connected to the mounting plate 1, the limiting portion 3 can return to its initial position to fix the aluminum substrate.

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the upper part of the limiting part 3 is constructed with an inclined surface that is tilted downward, and the lower part of the limiting part 3 is vertically against the side of the substrate 2. Through this design, the inclined surface design plays a role in guiding the correct installation of the substrate 2. When the substrate 2 is placed on the mounting plate 1, its side will first contact the inclined surface. As the substrate 2 is further placed, the inclined surface will gradually guide the substrate 2 to the correct position and tightly against the vertical part of the lower part. This design ensures the accuracy and stability of the substrate 2 during the installation process, avoids installation problems caused by position deviation, and the limiting part 3 can form a self-locking for the aluminum substrate, which is easy to operate and convenient for the subsequent connection of bolts and other components. Under the action of the limiting part 3 and the aluminum substrate being pressed against each other, the loosening of the aluminum substrate can be reduced.

[0041] like Figure 4 As shown, in the present embodiment, the limiting component also includes a winding portion 303 rotatably connected to the back of the mounting plate 1, and the surface of the winding portion 303 is wound with connecting members 302 that are all connected to the limiting portion 3 and penetrate the mounting plate 1, and can pull the limiting portion 3 to move in the horizontal direction. Through this design, when the aluminum substrate is subsequently removed, the winding portion 303 on the back of the mounting plate 1 can be rotated, and the winding portion 303 can synchronously pull and wind up multiple connecting members 302, so as to pull the limiting portion 3 through the connecting members 302, avoiding the need to operate the limiting portion 3 one by one, thereby improving continuity, and then the aluminum substrate can automatically pop up under the action of the elastic member 3 7, which is convenient for disassembly and assembly.

[0042] like Figure 2 , Figure 4 and Figure 5As shown, in this embodiment, the refrigeration component includes an elastic airbag 5 installed on the surface of the mounting plate 1 in an eccentric manner, and an air vent 501 located below the substrate 2 is provided on the surface of the elastic airbag 5. A refrigeration component 502 is installed inside the elastic airbag 5, and an arc-shaped vertical plate 503 is installed inside the elastic airbag 5. A telescopic rod 2 504 and an elastic component 2 505 located outside the telescopic rod 2 504 are respectively installed on one side of the vertical plate 503. Through this implementation, the opening of the air vent 501 allows cold air to flow out from the inside of the airbag and directly act on the bottom of the substrate 2 to achieve local refrigeration. The refrigeration component 502 is installed inside the airbag, generates cold air through the refrigeration effect, and releases it to the bottom of the substrate 2 through the air vent 501, while the telescopic rod 2 504 and the elastic component 2 505 are used to resist the elastic airbag 5 so as to push the elastic airbag 5 to recover.

[0043] like Figure 4-5 As shown, in this embodiment, the movable ends of the telescopic rod 2 504 and the elastic member 2 505 are both in contact with the elastic airbag 5, and the refrigeration member 502 is arranged in a ring shape. Through this design, a uniform refrigeration effect can be provided around the bottom of the substrate 2. It not only provides an adaptive support function, but also enables the refrigeration component to be adaptively supported according to the actual size and shape of the substrate 2. When the size or shape of the substrate 2 changes, the telescopic rod 2 504 will be extended and retracted as needed, and the elastic member 2 505 provides the necessary elasticity and supporting force to ensure that the airbag can fit tightly into the space below the substrate 2, thereby maintaining the stability and consistency of the refrigeration effect.

[0044] like Figure 3-4 As shown, in the present embodiment, the refrigeration assembly also includes a motor 6 installed on the back of the mounting plate 1, the output end of the motor 6 is connected to a drive shaft 602, and a cam 601 is installed at one end of the drive shaft 602 away from the motor 6. Through this implementation, in order to effectively dissipate the heat of the components, the motor 6 can be started at this time so that the motor 6 can drive the cam 601 to rotate through the drive shaft 602 after working. After the cam 601 rotates, it can cause a certain push on the elastic airbag 5, so that the elastic airbag 5 will be deformed after being subjected to force to compress the cold air inside it. With the rotation of the cam 601 and the eccentric setting of the elastic airbag 5, the elastic airbag 5 can also return to its original shape after being subjected to force, so as to continuously generate low-temperature air blowing toward the aluminum substrate.

[0045] like Figure 2 and Figure 4As shown, in this embodiment, the horizontal height of the cam 601 is lower than the horizontal height of the elastic airbag 5, and the cam 601 is coaxially arranged with the elastic airbag 5. Through this design, it is ensured that when the cam 601 rotates, one end thereof can directly and evenly squeeze the inner circle of the elastic airbag 5 to avoid collision interference with the aluminum substrate. Through the eccentric coaxial arrangement of the cam 601 and the elastic airbag 5, the cam 601 can regularly push the elastic airbag 5 to generate regular and uniform cold air, thereby improving the thermal conductivity of the aluminum substrate.

[0046] like Figure 1-4 As shown, in this embodiment, elastic members 3 7 with a horizontal height higher than that of the heat conducting member 4 are installed around the inner side of the mounting plate 1, and mounting seats 101 are fixed around the outer side of the mounting plate 1. The horizontal position of the mounting seats 101 is located below the connecting member 302. Through this implementation, the elastic member 3 7 is used to lift the aluminum substrate by itself when the aluminum substrate is dismantled, which is convenient for personnel to take. The mounting seat 101 provides a clear fixing point for the mounting plate 1, so that the installer can complete the installation work more quickly and accurately.

[0047] Working principle: When the device is used, the aluminum substrate is first installed into the mounting plate 1, and the aluminum substrate connected to the component can be aligned with the mounting plate 1. Then, during the downward connection process, the inclined limiting part 3 can guide and limit the aluminum substrate to a certain extent, and because of the inclined surface of its structure, it can promote its own movement during the connection process of the aluminum substrate, thereby compressing the elastic member 305 and the telescopic rod 304. Then, after being fully connected to the mounting plate 1, the limiting part 3 can be restored to the initial position to fix the aluminum substrate to form a self-locking, which is easy to operate and convenient for subsequent bolts. The connection of the components, and the looseness of the aluminum substrate can be reduced under the action of the pressure between the limiting part 3 and the aluminum substrate. When the aluminum substrate is subsequently removed, the winding part 303 on the back of the mounting plate 1 can be rotated so that the winding part 303 can synchronously pull and wind up multiple connecting members 302, so as to pull the limiting part 3 through the connecting member 302. At this time, the aluminum substrate can automatically pop up under the action of the elastic member 3 7, and the disassembly and assembly are convenient. After the aluminum substrate is installed, in order to effectively dissipate the heat of the components, the motor 6 can be started at this time so that the motor 6 can drive the cam through the driving shaft 602 after working. 601 rotates, and the cam 601 can push the elastic airbag 5 to a certain extent after rotating, so that the elastic airbag 5 will be deformed after being stressed to compress the air inside it, and the air at this time can be turned into low-temperature air under the action of the refrigeration component 502 to blow toward the aluminum substrate. With the rotation of the cam 601 and the eccentric setting of the elastic airbag 5, the elastic airbag 5 can also restore to its initial shape after being stressed to continuously generate low-temperature air blowing toward the aluminum substrate, and the telescopic rod 2 504 and the elastic component 2 505 therein are to further ensure that the elastic airbag 5 can be restored. When the aluminum substrate is used for heat conduction and cooling, since the heat conductor 4 is installed inside the mounting plate 1, the heat at the position of the aluminum substrate can be conducted to the back of the mounting plate 1 again through the conduction hole 103, so as to avoid the aluminum substrate and the mounting plate 1 being closely fitted, which makes it difficult to conduct and dissipate the heat. The heat of the surface components can form a passage for guidance and dissipation under the action of the aluminum substrate, the heat conductor 4 and the conduction hole 103, thereby improving the heat dissipation efficiency. Moreover, under the action of the conical positioning hole 102, the heat can also be guided to a certain extent and gathered at the position of the heat conductor 4, thereby improving the use effect.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
