Description

Technical Field

[0001] This utility model relates to the field of infrared lamp heat dissipation technology, and in particular to a heat-conducting structure and heat dissipation device. Background Technology

[0002] In existing technologies, a reflective coating is typically applied to infrared lamps. This reflective coating forms a mirror structure that reflects infrared radiation, redirecting and concentrating the backscattered light onto the target area. This reduces energy loss and improves heating or lighting effects. However, infrared lamps generate high temperatures during prolonged operation, which can damage the reflective coating due to oxidation. Therefore, timely heat dissipation is necessary for infrared lamps during extended operation.

[0003] One existing method for cooling infrared lamps involves placing a heat sink on the reflective coating of the lamp to conduct the heat generated during operation to the external environment. However, this method suffers from poor heat conduction between the reflective coating and the heat sink, and slippage can easily occur between them, further hindering heat dissipation and posing a risk of damage to the lamp from the heat sink.

[0004] Therefore, there is an urgent need for a heat-conducting structure and heat dissipation device to solve the above-mentioned technical problems. Utility Model Content

[0017] The beneficial effects of this utility model are:

[0018] On one hand, this utility model provides a heat-conducting structure. By covering the reflective coating of an infrared lamp with a first flexible filler layer, then a flexible heat-conducting layer on top of the first flexible filler layer, and finally a second flexible filler layer on top of the flexible heat-conducting layer, with one side of the second flexible filler layer in contact with the heat-conducting part, the heat generated by the infrared lamp is first conducted to the first flexible filler layer covering the reflective coating. Then, the heat is conducted through the flexible heat-conducting layer covering the first flexible filler layer to the second flexible filler layer, and finally, the second filler layer conducts the heat to the heat dissipation part it contacts. During this heat conduction process, the presence of the first and second flexible filler layers fills the tiny gaps between the flexible heat-conducting layer and the reflective coating, as well as between the flexible heat-conducting layer and the heat-conducting part, reducing the formation of voids, thereby lowering thermal resistance and improving heat conduction efficiency. Furthermore, multiple interconnected or non-interconnected holes are distributed on the flexible thermally conductive layer, and at least a portion of the first flexible filling layer and / or at least a portion of the second flexible filling layer can fill these holes.

Moreover, the presence of the first and second flexible filling layers prevents hard contact between the heat sink and the infrared lamp. Even if the heat sink and the infrared lamp collide, the first and second flexible filling layers act as a buffer, significantly reducing the risk of damage to the infrared lamp. Simultaneously, the material properties of the first and second flexible filling layers increase the friction between the heat sink and the reflective coating of the infrared lamp, preventing slippage between them. This further improves heat conduction efficiency and reduces the risk of damage to the infrared lamp.

Moreover, during the heat dissipation process using the aforementioned heat dissipation device, no additional power components or cold sources are required, saving installation space, facilitating equipment installation and layout, and improving the applicability of the aforementioned heat dissipation device.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] On the one hand, such as Figure 1 As shown, this embodiment provides a heat-conducting structure 10, which is used to conduct the heat generated by the infrared lamp tube 20 to a heat dissipation part, such as a heat sink or a heat dissipation block. A reflective coating is provided on one side of the infrared lamp tube 20. The heat-conducting structure 10 includes: a first flexible filling layer 1, a flexible heat-conducting layer 2, and a second flexible heat-conducting layer 2.

[0031] The first flexible filling layer 1 can cover the reflective coating provided on the infrared lamp tube 20. It is easy to understand that since the infrared lamp tube 20 has a long strip-shaped tubular structure, the reflective coating provided on the infrared lamp tube 20 also has a long strip-shaped structure. Therefore, the first flexible filling layer 1 is a long strip-shaped sheet structure.

[0032] The aforementioned flexible thermally conductive layer 2 covers the side of the first flexible filler layer 1 that faces away from the reflective coating. That is, with... Figure 1 Taking the shown perspective as an example, the flexible thermally conductive layer 2 covers the upper side of the first flexible filling layer 1. Similarly to the first flexible filling layer 1, the flexible thermally conductive layer 2 is also a long strip-shaped sheet structure.

[0033] The aforementioned second flexible filler layer 3 covers the side of the flexible thermally conductive layer 2 that faces away from the first flexible filler layer 1. That is, with Figure 1 Taking the shown perspective as an example, the second flexible filling layer 3 covers the upper side of the aforementioned flexible thermally conductive layer 2. Similar to the first flexible filling layer 1, the second flexible filling layer 3 is also a long, strip-shaped sheet structure. The other side of the second flexible filling layer 3 contacts the heat dissipation part, enabling it to conduct the heat generated by the infrared lamp 20 to the heat dissipation part. It is easy to understand that the heat generated by the infrared lamp 20 is first conducted to the first flexible filling layer 1 covering the reflective coating, then the heat is conducted through the flexible thermally conductive layer 2 covering the first flexible filling layer 1 to the second flexible filling layer 3, and finally, the second filling layer conducts the heat to the heat dissipation part it contacts.

[0034] The aforementioned flexible thermally conductive layer 2 has multiple interconnected or non-interconnected holes. At least a portion of the first flexible filling layer 1 and / or at least a portion of the second flexible filling layer 3 can fill these holes.

[0035] Here, the way in which at least a portion of the first flexible filling layer 1 and / or at least a portion of the second flexible filling layer 3 fills the holes on the flexible thermal conductive layer 2 is as follows: due to the properties of the flexible material, when the first flexible filling layer 1 is compressed, the portion of the first flexible filling layer 1 located at the opening of the hole will deform, and the deformed portion will fill along the inside of the hole towards the second flexible filling layer 3; or, due to the properties of the flexible material, when the second flexible filling layer 3 is compressed, the portion of the second flexible filling layer 3 located at the opening of the hole will deform, and the deformed portion will fill along the inside of the hole towards the first flexible filling layer 1; or, due to the properties of the flexible material, when both the first flexible filling layer 1 and the second flexible filling layer 3 are compressed, the portions of both the first flexible filling layer 1 and the second flexible filling layer 3 located at the opening of the hole will deform, and the deformed portions of both will simultaneously fill along the inside of the hole towards each other.

[0036] Therefore, the heat-conducting structure 10 provided in this embodiment covers a first flexible filling layer 1 on the reflective coating of the infrared lamp tube 20, a flexible heat-conducting layer 2 on the first flexible filling layer 1, and a second flexible filling layer 3 on the flexible heat-conducting layer 2, with one side of the second flexible filling layer 3 in contact with the heat-conducting part. This allows the heat generated by the infrared lamp tube 20 to be first conducted to the first flexible filling layer 1 covering the reflective coating, then conducted through the flexible heat-conducting layer 2 covering the first flexible filling layer 1 to the second flexible filling layer 3, and finally conducted by the second filling layer to the heat dissipation part it contacts. During this heat conduction process, the presence of the first flexible filling layer 1 and the second filling layer fills the tiny gaps between the flexible heat-conducting layer 2 and the reflective coating, as well as between the flexible heat-conducting layer 2 and the heat-conducting part, reducing the generation of voids, thereby reducing thermal resistance and improving heat conduction efficiency. In addition, multiple interconnected or non-interconnected holes are distributed on the flexible heat-conducting layer 2, and at least part of the first flexible filling layer 1 and / or at least part of the second flexible filling layer 3 can fill the holes. This allows the portion of the first flexible filling layer 1 and / or the second flexible filling layer 3 filled in the holes to a certain extent to limit and fix the flexible heat-conducting layer 2, preventing the position of the flexible heat-conducting layer 2 from shifting, and ensuring that the flexible heat-conducting layer 2 is in a suitable position to perform its heat-conducting effect normally. Furthermore, due to the provision of the first flexible filling layer 1 and the second filling layer, hard contact between the heat dissipation part and the infrared lamp tube 20 can be avoided. Even if the heat dissipation part and the infrared lamp tube 20 collide, the first flexible filling layer 1 and the second filling layer can also play a buffering role, greatly reducing the risk of the infrared lamp tube 20 being damaged. At the same time, due to the material properties of the first flexible filling layer 1 and the second filling layer, the friction between the heat dissipation part and the reflective coating of the infrared lamp tube 20 can be increased, preventing slippage between the heat dissipation part and the infrared lamp tube 20. This can not only improve the heat conduction efficiency, but also further reduce the risk of the infrared lamp tube 20 being damaged.

[0037] In some embodiments, the first flexible filler layer 1 and the second flexible filler layer 3 are both carbon cloth layers. Of course, the first flexible filler layer 1 and the second flexible filler layer 3 can also be configured with other structures, such as silicone grease layers or composite material layers (e.g., silicone grease layers doped with metal particles). In some embodiments, the flexible thermally conductive layer 2 is a flexible metal layer or a foamed metal layer. When the flexible thermally conductive layer 2 is a flexible metal layer, it can be a copper mesh, a copper foil layer, an aluminum foil layer, etc.; when the flexible thermally conductive layer 2 is a foamed metal layer, it can be foamed copper.

[0038] In some embodiments, the thickness of the first flexible filler layer 1 is equal to the thickness of the second flexible filler layer 3. The ratio of the thickness of the first flexible filler layer 1 or the second flexible filler layer 3 to the thickness of the flexible thermal conductive layer 2 ranges from 1:3 to 5:1. Taking the thickness of the first flexible filler layer 1 or the second flexible filler layer 3 as L1 and the thickness of the flexible thermal conductive layer 2 as L2 as an example. For example, if the ratio is 1:3, that is, the thickness of the first flexible filler layer 1 or the second flexible filler layer 3 is 0.1 mm and the thickness of the flexible thermal conductive layer 2 is 0.3 mm, 3L1=L2; or if the ratio is 1:2, that is, the thickness of the first flexible filler layer 1 or the second flexible filler layer 3 is 0.1 mm and the thickness of the flexible thermal conductive layer 2 is 0.2 mm, 2L1=L2; or if the ratio is 2:1, that is, the thickness of the first flexible filler layer 1 or the second flexible filler layer 3 is equal to the thickness of the second flexible filler layer 3. The thickness of the first flexible filling layer 1 is 0.2 mm, and the thickness of the flexible thermal conductive layer 2 is 0.1 mm, so L1 = 2L2. Alternatively, the ratio is 4:1, meaning the thickness of either the first or second flexible filling layer 3 is 0.4 mm, and the thickness of the flexible thermal conductive layer 2 is 0.1 mm, so L1 = 4L2. Or, the ratio is 5:1, meaning the thickness of either the first or second flexible filling layer 3 is 0.5 mm, and the thickness of the flexible thermal conductive layer 2 is 0.1 mm, so L1 = 5L2. Through these settings, the thicknesses of the first flexible filling layer 1, the second flexible filling layer 3, and the flexible thermal conductive layer 2 are within a reasonable range that matches actual needs. This ensures efficient heat conduction through the flexible thermal conductive layer 2, while also fully filling the small gaps through the two filling layers, thus maintaining the protective performance of the structure.

[0039] In some embodiments, combined with Figure 1 , Figure 2 , Figure 3 As shown, the infrared lamp tube 20 extends along a first direction X1. The infrared lamp tube 20 includes a plurality of sub-tubes arranged along a second direction X2. Here, the second direction X2 is set at an angle to the first direction X1, for example, 90°. The heat-conducting structure 10 extends along the first direction X1 and includes a plurality of first bends 21 and second bends 22 arranged along the second direction X2. The bending direction of the first bends 21 is opposite to the bending direction of the second bends 22. Figure 1 Taking the shown viewpoint as an example, the first curved part 21 bends upward and the second curved part 22 bends downward.

[0040] The first bend 21 is respectively provided with one-to-one correspondence with the sub-tube body and is adapted to the outer surface of the sub-tube body. It is easy to understand that "adapted" here means that the curvature of the first bend 21 is the same as the curvature of the outer surface of the sub-tube body. The second bend 22 is provided directly opposite the connection part between two adjacent sub-tube bodies and is adapted to the connection part between two adjacent sub-tube bodies. It is easy to understand that "adapted" here means that the curvature of the second bend 22 is the same as the curvature of the connection part between two adjacent sub-tube bodies.

[0041] Through the above-described configuration, the heat-conducting structure 10 can adapt to the outer surface of different types of infrared lamps 20 without complex adjustments, ensuring heat conduction performance for different types of infrared lamps 20 and improving the applicability of the heat-conducting structure 10. It is easy to understand that different types of infrared lamps 20 refer to different numbers of sub-tubes in the infrared lamp 20.

[0042] On the other hand, the embodiment provides a heat dissipation device, combined with Figure 2 , Figure 3 As shown, the heat dissipation device includes a heat dissipation assembly 4 and a heat-conducting structure 10 as described in any of the embodiments above.

[0043] The aforementioned heat dissipation assembly 4 extends along a first direction X1, which is the extending direction of the infrared lamp tube 20. A mounting groove is provided on the heat dissipation assembly 4, and the infrared lamp tube 20 is at least partially disposed in this mounting groove. Figure 3 Taking the shown perspective as an example, the upper part of the infrared lamp tube 20 is installed in the mounting groove of the heat dissipation assembly. It is easy to understand that since the infrared lamp tube 20 is a long, narrow tubular structure, the mounting groove 11 is also a long, narrow groove, and the extending direction of the mounting groove is the same as the extending direction of the infrared lamp tube 20. The heat-conducting structure 10 is disposed between the reflective coating and the inner wall of the mounting groove on the heat dissipation assembly 4. One side of the heat-conducting structure 10 contacts the inner wall of the mounting groove, enabling it to conduct the heat generated by the infrared lamp tube 20 to the heat dissipation assembly 4. Furthermore, the heat dissipation assembly 4 can conduct the heat generated by the infrared lamp tube 20 to the external environment, thereby completing the heat dissipation of the infrared lamp tube 20.

[0044] This heat dissipation device includes all the technical features of the heat-conducting structure 10 described above, and has the same beneficial effects as the heat-conducting structure 10, which will not be repeated here. Furthermore, during the heat dissipation process using the above-mentioned heat dissipation device, the use of a solid component instead of air to transfer heat improves heat conduction efficiency and ensures effective heat dissipation for the infrared lamps. Simultaneously, the heat dissipation device utilizes heat conduction and natural convection to dissipate heat; its heat dissipation process is passive, avoiding any impact on the production environment. Moreover, during the heat dissipation process using the above-mentioned heat dissipation device, no additional power components or cold sources are required, saving installation space, facilitating equipment installation and layout, and improving the applicability of the above-mentioned heat dissipation device.

[0045] In some embodiments, combined with Figure 2 , Figure 3 As shown, the infrared lamp tube 20 includes multiple sub-tubes arranged along a second direction X2. Here, the second direction X2 forms an angle with the first direction X1 mentioned above, for example, 90°. Exemplarily, the infrared lamp tube 20 includes two sub-tubes, both extending along the first direction X1 and arranged along the second direction X2. The mounting groove on the heat dissipation assembly 4 includes multiple arc-shaped mounting slots arranged along the second direction X2 and interconnected. The arc-shaped mounting slots are adapted to the sub-tubes of the infrared lamp tube 20; that is, the curvature of the arc-shaped mounting slot is the same as, or slightly greater than, the curvature of, the outer contour of the sub-tube. The multiple sub-tubes correspond one-to-one with the multiple arc-shaped mounting slots. For example, the aforementioned mounting groove includes two arc-shaped mounting slots 111, both extending along the first direction X1 and arranged along the second direction X2. The two sub-tubes are respectively configured to correspond one-to-one with these two arc-shaped mounting slots. It is easy to understand that the number of sub-tubes and the number of arc-shaped mounting slots can also be set to other numbers, such as three or four. Those skilled in the art can set these according to actual usage requirements; an exhaustive list is not provided here.

[0046] Through the above settings, the heat dissipation assembly 4 of the heat dissipation device can be adapted to different models of infrared lamp tubes 20, thereby improving the applicability of the heat dissipation device.

[0047] In some embodiments, the heat dissipation assembly 4 is a one-piece molded structure. The heat dissipation assembly 4 is manufactured, for example, by die casting, sand casting, or additive manufacturing. This arrangement simplifies the production process of the heat dissipation assembly 4, reduces hidden costs, and improves overall performance and reliability.

[0048] Of course, the heat dissipation assembly 4 mentioned above can also be configured with other structures.

[0049] In some embodiments, such as Figure 3As shown, the aforementioned heat dissipation assembly 4 includes a mounting base 41 extending along a first direction X1 and a heat dissipation component 42 detachably mounted on the mounting base 41. The heat dissipation component 42 is disposed on the side of the mounting base 41 opposite to the infrared lamp tube 20, and a mounting groove is disposed on the other side of the mounting base 41. The heat dissipation component 42 is, for example, a heat dissipation fin assembly. The aforementioned mounting base 41 can transfer the heat generated by the infrared lamp tube 20 to the heat dissipation component 42, and then the heat generated by the infrared lamp tube 20 can be conducted to the external environment through the heat dissipation component 42. It is easy to understand that the materials of the aforementioned mounting base 41 and heat dissipation component 42 can be various, such as metallic materials (copper, aluminum, etc.), non-metallic materials (silicon carbide, aluminum nitride, etc.), and composite materials (polymer matrix filled with thermally conductive filler), as long as good thermal conductivity can be achieved. Those skilled in the art can flexibly set them according to actual usage requirements.

[0050] For example, such as Figure 3 As shown, the mounting base 41 includes a first base 411 and a second base 412 arranged along the second direction X2. Both the first base 411 and the second base 412 are detachably connected to the heat dissipation assembly 42, and both can slide along the second direction X2. It is easy to understand that the first base 411 and the second base 412 extend along the first direction X1. The way in which the first base 411 and the heat dissipation assembly 42 are detachably slidably connected is, for example, as follows: a slide rail extending along the second direction X2 or a slide groove passing through the first base 411 along the second direction X2 is provided on the upper side of the first base 411, and a slide groove or a slide rail extending along the second direction X2 is provided at a corresponding position on the lower side of the heat dissipation assembly 42. The slide rail or slide groove on the upper side of the first base 411 is adapted to the slide groove or slide rail on the lower side of the heat dissipation assembly 42. The aforementioned slide rail is, for example, a dovetail slide rail or an inverted trapezoidal slide rail, and the aforementioned slide groove is correspondingly a dovetail slide groove or an inverted trapezoidal slide groove. The first seat 411 and the heat dissipation assembly 42 are detachably slidably connected through the cooperation of the slide rail and the slide groove. The detachable slidable connection between the second seat 412 and the heat dissipation assembly 42 is achieved in the same way, and will not be described again here.

[0051] Both the first base 411 and the second base 412 are provided with arc-shaped mounting grooves. The arc-shaped mounting grooves on the first base 411 and the second base 412 can be combined to form a mounting recess.

[0052] With the above-mentioned configuration, the heat dissipation device can be adapted to infrared lamp tubes 20 of different sizes simply by disassembling and replacing the mounting base 41 of different sizes, without the need to replace or reprocess the heat dissipation component 42, thus saving material costs. At the same time, it is convenient to disassemble and install, making it easy to use and further improving the practicality of the heat dissipation device.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
