Description

Technical Field

[0001] This utility model relates to the field of auxiliary lighting devices, and in particular to a heat dissipation device for stadium lighting. Background Technology

[0002] Sports stadium lighting typically uses high-power LEDs, and currently, heat dissipation for these LEDs mainly relies on passive cooling, primarily achieved by installing fins on the casing. However, the effectiveness of passive cooling remains limited. Furthermore, sports stadiums often have internal airflow designs, and current cooling systems lack the ability to optimize for these airflow patterns, requiring further development and improvement. Utility Model Content

[0003] The present invention aims to improve at least one technical problem in the prior art.

[0004] This utility model provides a heat dissipation device for stadium lighting, comprising:

[0005] Base;

[0006] A heat dissipation back cover is connected to the base and encloses it to form a mounting cavity for mounting lighting fixtures; a heat dissipation groove is provided on the side of the heat dissipation back cover facing away from the mounting cavity.

[0007] The finned body includes a base plate and a plurality of heat dissipation fins connected to the base plate. The heat dissipation fins are arranged in parallel in the transverse direction. The base plate is inside the heat dissipation groove and is attached to the heat dissipation back cover. The extending direction of the heat dissipation fins is the same as the extending direction of the base plate.

[0008] A fan, which is mounted on a finned body, and the airflow direction of the fan is the same as the extension direction of the heat dissipation fins;

[0009] An adjustable mounting structure is provided, in which the fins are mounted on the heat dissipation back cover, allowing the fins to be mounted on the heat dissipation back cover in different orientations.

[0010] The beneficial effects of this utility model are as follows: The base plate of the finned body of the heat dissipation device allows the finned body to be installed on the heat dissipation back cover in different directions through the adjustable installation structure. The air outlet direction of the fan can be changed according to the ventilation direction of the venue, so that the heat dissipation device has the ability to adjust according to the ventilation direction of the venue, which is conducive to improving the heat dissipation efficiency of the heat dissipation device and helps to reduce the operating temperature of the lighting device.

[0011] As a sub-solution of the above technical solution, the repositioning installation structure includes a first mounting hole and a second mounting hole. Both the first and second mounting holes are located on the side of the heat sink cover facing away from the mounting cavity. The base plate has a fixing hole, and a screw passes through the fixing hole. The screw passes through the fixing hole and is threadedly connected to either the first or second mounting hole, allowing the base plate to be fixed to the heat sink cover in different orientations. This structure allows for easy fixing of the base plate to the heat sink cover in different mounting orientations. Specifically, in the assembled state, the screw through the fixing hole locks the base plate to the heat sink cover, fixing the fins in the first orientation. When it is necessary to change the orientation of the fins, loosen the screw and align the fixing hole with the second mounting hole to switch the fins to the second orientation. Then, screw the screw in again to fix the fins in the second orientation.

[0012] As a sub-solution of the above technical solution, the number of fixing holes is four, and the four fixing holes are distributed in a square. The first mounting hole and the second mounting hole form a square-distributed hole array. Setting the number of fixing holes to four makes the force on the fixing base plate more balanced, and the fit between the base plate and the heat dissipation cover is better, which is conducive to improving the heat conduction efficiency of the fins to the heat dissipation cover.

[0013] As a sub-solution of the above technical solution, a sealing groove is provided at the bottom of the base plate, and a sealing ring is provided at the sealing groove, the sealing ring abutting against the outer wall of the heat dissipation groove. By creating and fitting a sealing ring at the bottom of the base plate, and applying thermal grease to the bottom wall of the base plate and the heat dissipation groove (i.e., the wall adjacent to the mounting cavity), external dust and impurities are facilitated to enter the heat dissipation groove, reducing the possibility of dust and impurities damaging the lifespan of the heat dissipation device.

[0014] As a sub-solution of the above technical solution, the finned body further includes a heat pipe, and the base plate and the heat dissipation fins are connected to the base plate through the heat pipe.

[0015] As some sub-solutions of the above technical solution, the fin body also includes locking pins and fixing components. The fan is located on one side of the heat dissipation fins and has a locking hole. The fixing component includes a connecting rod and a retaining plate. The connecting rod has a screw hole on the side adjacent to the fan. The locking pin passes through the locking hole and is threadedly connected to the screw hole so that the fan and the retaining plate abut against the two sides of the heat dissipation fins respectively.

[0016] As a sub-solution of the above technical solution, one side of the heat dissipation fin is also provided with a groove, and the fan also includes a hook, which is accommodated in the groove. Attached Figure Description

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The following is combined Figures 1 to 4 The embodiments of this utility model are described below.

[0032] like Figure 4As shown, due to the limitations of venue installation and lighting requirements, the orientation of the lamps and their corresponding bases 1 and heat dissipation covers 2 is predetermined. However, the ventilation direction of the venue may vary depending on the installation location. Therefore, when installing a heat dissipation device with a fan 4, if the fan 4's airflow direction cannot be adjusted according to the ventilation direction, it will lead to inconsistent heat dissipation efficiency, inconsistent lifespan, and inconsistent lighting effects among the lamps. This utility model provides a heat dissipation device for stadium lighting, aiming to improve the overall heat dissipation performance and environmental adaptability of the device. The ventilation design of a stadium is usually determined before construction. The heat dissipation device of this utility model can change the installation angle according to the pre-set ventilation design to achieve better heat dissipation and make the heat dissipation devices throughout the venue as consistent as possible in terms of heat dissipation efficiency.

[0033] This embodiment of a heat dissipation device for stadium lighting includes:

[0034] Base 1;

[0035] A heat dissipation back cover 2 is connected to the base 1 and forms an installation cavity 10, which is used to install lighting fixtures; a heat dissipation groove 21 is provided on the side of the heat dissipation back cover 2 facing away from the installation cavity 10.

[0036] The finned body 3 includes a base plate 32 and a plurality of heat dissipation fins 31 connected to the base plate 32. The heat dissipation fins 31 are arranged in parallel in the transverse direction. The base plate 32 is in the heat dissipation groove 21 and is attached to the heat dissipation back cover 2. The extending direction of the heat dissipation fins 31 is the same as the extending direction of the base plate 32.

[0037] Fan 4 is mounted on finned body 3, and the air outlet direction of fan 4 is the same as the extension direction of heat dissipation fin 31.

[0038] The finned body 3 is mounted on the heat dissipation back cover 2 via the adjustable mounting structure, which allows the finned body 3 to be mounted on the heat dissipation back cover 2 in different directions.

[0039] The base plate 32 of the finned body 3 of this heat dissipation device allows the finned body 3 to be installed on the heat dissipation back cover 2 in different directions via an adjustable mounting structure. This allows the fan 4 to change its exhaust direction according to the venue's ventilation direction, enabling the heat dissipation device to adjust accordingly. This improves the heat dissipation efficiency and helps reduce the operating temperature of the lighting equipment. The fan 4 is designed to achieve forced convection cooling, which is more efficient than natural convection. During installation, aligning the fan 4 with the venue's ventilation direction increases airflow speed and further enhances the heat dissipation efficiency of the device.

[0040] The heat dissipation cover 2 is the base of the entire heat dissipation device, connected to the base 1, together forming a mounting cavity 10. This mounting cavity 10 provides a protected mounting space for core components of the lighting fixture, such as LED light source modules and driver power supplies. The function of the heat dissipation cover 2 goes beyond structural support and protection; its more important role is as the first stage of heat conduction. In actual operation, the heat generated by the lighting fixture within the mounting cavity 10 is first conducted to the heat dissipation cover 2. To effectively dissipate this heat, the heat dissipation cover 2 has a heat dissipation groove 21 on its outer surface, facing away from the mounting cavity 10. This heat dissipation groove 21 can be a recessed structure to accommodate a portion of the finned body 3 and increase the contact area between the heat dissipation cover 2 and the finned body 3, thereby promoting heat transfer.

[0041] The finned body 3 is the core component responsible for heat dissipation. The finned body 3 includes a base plate 32 and several heat dissipation fins 31 connected to the base plate 32. The base plate 32 forms the foundation of the finned body 3, and its main function is to receive heat transferred from the heat dissipation cover 2. During installation, the base plate 32 of the finned body 3 is placed within the heat dissipation groove 21 of the heat dissipation cover 2 and is tightly fitted to the groove 21 to ensure a good thermal conductivity path is formed between them. To further improve thermal conductivity, thermal grease can be applied between the base plate 32 and the heat dissipation cover 2. The several heat dissipation fins 31 are connected to the base plate 32 and arranged in parallel laterally, effectively increasing the total surface area in contact with the surrounding air. The extending direction of the heat dissipation fins 31 is the same as the extending direction of the base plate 32; this design facilitates the formation of a regular airflow channel.

[0042] The fan 4 is mounted on the finned body 3, typically located at one end or above the array of heat dissipation fins 31. The power supply for the fan 4 can be connected to the lamp plate mounted inside the mounting cavity 10.

[0043] The adjustable mounting structure allows the fins 3 to be mounted on the heat sink cover 2 in different orientations. The adjustable mounting structure includes a first mounting hole 22 and a second mounting hole 23, both located on the side of the heat sink cover 2 facing away from the mounting cavity 10. The base plate 32 has a fixing hole 321, through which a screw (not shown in the figure) passes. The screw passes through the fixing hole 321 and is threaded into either the first mounting hole 22 or the second mounting hole 23, allowing the base plate 32 to be fixed to the heat sink cover 2 in different orientations. This structure allows for easy fixing of the base plate 32 to the heat sink cover 2 in different mounting orientations. Specifically, in the assembled state, the screws through the fixing holes 321 lock the base plate 32 onto the heat dissipation back cover 2, so that the fin body 3 is fixed in the first orientation; when it is necessary to change the orientation of the fin body 3, loosen the screws and then align the fixing holes 321 with the second mounting holes 23, so that the fin body 3 is switched to the second orientation, and then screw in the screws again to fix the fin body 3 in the second orientation.

[0044] In this embodiment, the base plate 32 of the finned body 3 has four fixing holes 321 arranged in a square. Correspondingly, the first mounting hole 22 and the second mounting hole 23 on the heat dissipation cover 2 also form a square-arranged hole array. During installation, screws are passed sequentially through the four fixing holes 321 on the base plate 32 and then selectively threaded into the first mounting hole 22 or the second mounting hole 23 on the heat dissipation cover 2. For example, the fixing holes 321 of the base plate 32 can be aligned with the first mounting hole 22 and fixed with screws to achieve one installation direction; alternatively, the finned body 3 can be rotated 90 degrees to align the fixing holes 321 on its base plate 32 with the second mounting hole 23 and fix them to achieve another installation direction. This design allows the finned body 3 to be easily adjusted in four directions: 0 degrees, 90 degrees, 180 degrees, and 270 degrees, adapting to the ventilation design of the venue. Four fixing holes 321 are provided, resulting in more balanced force distribution on the fixing base plate 32 and better fit between the base plate 32 and the heat dissipation cover 2, which is beneficial to improving the heat conduction efficiency of the fins 3 to the heat dissipation cover 2. More specifically, each of the four fixing holes 321 is connected to its corresponding first mounting hole 22 or second mounting hole 23 by screws. Since the four fixing holes 321 are arranged in a square, the hole array formed by the first mounting holes 22 and the second mounting holes 23 is also square. Therefore, after adjusting the installation position in four directions (0 degrees, 90 degrees, 180 degrees, and 270 degrees), it can be fixed with four screws.

[0045] Considering that stadium lighting fixtures are typically installed outdoors, they need to have good waterproof and dustproof capabilities. Specifically, a sealing groove is provided at the bottom of the base plate 32, and a sealing ring 5 is provided at the sealing groove. The sealing ring 5 abuts against the outer wall of the heat dissipation groove 21. The sealing ring 5 is installed inside the sealing groove. When the fin body 3 is fastened to the heat dissipation cover 2 with screws, the sealing ring 5 is compressed and tightly abuts against the outer wall of the heat dissipation groove 21 or the surface of the heat dissipation cover 2, forming an effective sealing barrier and ensuring the reliability of the device's long-term stable operation.

[0046] A sealing groove is opened at the bottom of the base plate 32 and a sealing ring 5 is fitted. When thermal grease is applied to the bottom wall of the base plate 32 and the heat dissipation groove 21, that is, the wall adjacent to the mounting cavity 10, it is beneficial for external dust and impurities to enter the heat dissipation groove 21, reducing the possibility of damage to the life of the heat dissipation device due to dust and impurities.

[0047] To further enhance the heat transfer efficiency from the base plate 32 to the distal end of the heat dissipation fins 31, the fin body 3 also includes heat-conducting pipes. These heat-conducting pipes are internally vacuum-sealed and contain a small amount of thermally conductive medium, which is used to efficiently transfer heat. One end of the heat-conducting pipe is embedded in the base plate 32 to fully absorb heat from the lighting fixture, while the other end extends through and connects to multiple heat dissipation fins 31. When the base plate 32 is heated, the working fluid inside the heat-conducting pipe evaporates, the vapor flows to the portion extending through the heat dissipation fins 31 and condenses, releasing heat. The condensate then flows back to the heated end by gravity or internal capillary structures, repeating this cycle to rapidly and evenly distribute heat to each heat dissipation fin 31.

[0048] The fin body 3 also includes locking pins 6 and fixing members 7. The fan 4 is located on one side of the heat dissipation fins 31 and has a locking hole. The fixing member 7 includes a connecting rod and a retaining plate. The connecting rod has a screw hole on the side adjacent to the fan 4. The locking pin 6 passes through the locking hole and is threaded into the screw hole, so that the fan 4 and the retaining plate abut against both sides of the heat dissipation fins 31 respectively. During installation, the fan 4 is placed in the predetermined position, and the connecting rod of the fixing member 7 is inserted into the gap between the fins, so that the retaining plate abuts against the fin on the other side. Then, the locking pin 6 is passed through the locking hole on the frame of the fan 4 and threaded into the screw hole on the connecting rod. After tightening the locking pin 6, the frame of the fan 4 and the retaining plate of the fixing member 7 will tightly clamp the heat dissipation fins 31 from both sides, thereby firmly fixing the fan 4 to the fin body 3.

[0049] To ensure a stable connection between the fan 4 and the finned body 3, a groove 311 is provided on one side of the heat dissipation fin 31. The fan 4 also includes a latch 41, which is accommodated within the groove 311. During installation, the latch 41 of the fan 4 can be first placed into the groove 311 on the fin for initial positioning and support, and then the locking pin 6 and the fastener 7 can be used for final tightening. This combination method makes the installation of the fan 4 more convenient and reliable.
