Description

Technical Field

[0001] This utility model belongs to the field of reflector technology and relates to a reflector that can enhance heat dissipation performance. Background Technology

[0002] In existing technologies, reflectors, as key components of optical equipment, primarily serve the functions of light reflection and convergence, but their heat dissipation performance is often overlooked. Most traditional reflectors do not have dedicated heat dissipation structures, and during long-term operation, the heat generated by the lamps tends to accumulate inside the reflector, which not only affects light reflection efficiency but may also cause the reflector material to age and the lamp's lifespan to be shortened due to high temperatures. Even if some reflectors have added heat dissipation components, the heat dissipation effect is fixed and cannot be adjusted. It is impossible to flexibly adjust the heat dissipation capacity according to the amount of heat generated under different operating conditions, making it difficult to adapt to the heat dissipation requirements of the equipment under different power and different operating times, resulting in problems such as insufficient or excessive heat dissipation and energy waste.

[0003] For example, a Chinese patent discloses an LED heat dissipation reflector structure [application number: 201620578671.0], which includes an upper lamp housing, a circuit box assembled inside the upper lamp housing, and a power wire stretched downward; a lower reflector is assembled below the upper lamp housing, and a waterproof strip is provided between the lamp housing and the reflector, which is suitable for outdoor rainproof and weather-resistant. The lower reflector has a top plane, which extends from top to bottom to a bottom surface of a set size to form a large area heat dissipation component. A light-emitting body is fixed to the inner surface of the top plane of the lower reflector, and the power wire passes through the top plane and is electrically connected to the light-emitting body. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a reflector that can enhance heat dissipation performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reflector with enhanced heat dissipation performance includes a conical reflector disposed within a housing. A heat dissipation plate is disposed on the back of the reflector. The heat dissipation plate is inclined and its inclination direction is parallel to the generatrix of the reflector. The inner and outer sidewalls of the heat dissipation plate are arc surfaces. The inner sidewall of the heat dissipation plate can contact the back of the reflector. When the inner sidewall of the heat dissipation plate is not in contact with the reflector, the vertical distance between the inner sidewall of the heat dissipation plate and the reflector decreases from the middle of the heat dissipation plate to the left and right sides. The housing is also provided with an adjustment mechanism that drives the heat dissipation plate to move closer to or further away from the reflector. The heat dissipation plate is also provided with a heat transfer structure.

[0007] In the above-mentioned reflector that can enhance heat dissipation performance, the adjustment mechanism includes a connecting plate fixed in the middle of the outer side wall of the heat sink plate. The connecting line between the connecting plate and the heat sink plate is parallel to the generatrix of the reflector. The connecting plate is vertically arranged and its top end is fixedly connected to the connecting plate mounting plate. The housing is also provided with at least two drivers. The output shaft of the driver is fixedly connected to the connecting plate mounting plate and can drive the connecting plate mounting plate to reciprocate along the axial direction of the reflector.

[0008] After the driver moves the heat sink downwards until it contacts the left and right sides of the heat sink and the reflector, the force generated by the driver when it continues to move the heat sink downwards can work with the back of the reflector to compress the heat sink. After the heat sink is compressed and deformed, it can gradually contact the back of the reflector from the sides to the middle.

[0009] In the aforementioned reflector designed to enhance heat dissipation, the driver is a linear motor.

[0010] In the aforementioned reflector that enhances heat dissipation performance, the driver is fixed to the top of the inner wall of the housing, and a heat insulation cover is provided on the outside of the driver. The housing is also provided with heat dissipation holes that connect the inner cavity of the heat insulation cover to the outside.

[0011] In the aforementioned reflector that enhances heat dissipation performance, the heat transfer structure includes a heat dissipation channel disposed inside the heat dissipation plate. The connecting plate has end plates symmetrically disposed on both sides of the connection part with the heat dissipation plate. The end plates are provided with connection holes connected to the heat dissipation channel. The outer end of the connection hole is connected to a heat dissipation hose for connecting air-cooled equipment or water-cooled equipment.

[0012] In the aforementioned reflector that enhances heat dissipation performance, the connecting plate mounting plate is further provided with an annular input channel and an output channel. The outer end of the heat dissipation hose for inputting cooling medium, which is connected to the connecting hole, is uniformly connected to the input channel, and the outer end of the heat dissipation hose for outputting cooling medium, which is connected to the connecting hole, is uniformly connected to the output channel.

[0013] In the aforementioned reflector that enhances heat dissipation performance, the cross-section of the connecting plate mounting plate is annular, and a central hole corresponding to the lamp mounting hole on the reflector is provided at the center of the connecting plate mounting plate.

[0014] In the aforementioned reflector that enhances heat dissipation performance, three heat dissipation plates are provided on the back of the reflector, and the three heat dissipation plates are distributed circumferentially along the axis of the reflector.

[0015] In the aforementioned reflector that enhances heat dissipation performance, the bottom of the outer side wall of the reflector is provided with several reflector fixing plates with bolt holes along the circumferential direction, and the reflector is fixed in the housing by the reflector fixing plates.

[0016] In the aforementioned reflector that enhances heat dissipation performance, the heat sink is made of a thermally conductive material with deformation recovery properties.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] 1. The reflector features a tilted heat dissipation plate with curved sidewalls on its back, the tilt direction of which is parallel to the reflector's generatrix. An adjustment mechanism moves the heat dissipation plate closer to or further away from the reflector, adjusting the contact area between the heat dissipation plate and the reflector. Combined with the heat transfer structure within the heat dissipation plate, flexible adjustment of heat dissipation performance is achieved. When the heat dissipation plate is not in contact with the reflector, it does not deform. At this time, the vertical distance between the inner sidewall of the heat dissipation plate and the reflector decreases from the center to the sides. The adjustment mechanism moves the heat dissipation plate until it contacts the reflector, causing deformation. By controlling the distance, the contact area between the heat dissipation plate and the reflector can be adjusted to meet different heat dissipation needs, effectively solving the problems of traditional reflectors lacking heat dissipation function or having unadjustable heat dissipation effects.

[0019] 2. The adjustment mechanism, through the cooperation of the connecting plate, the mounting plate of the connecting plate and the driver, drives the heat sink to move along the axis of the reflector. When the heat sink moves down to the sides and contacts the reflector, the continuous force of the driver can squeeze the heat sink to deform it, and gradually contact the back of the reflector from the sides to the middle. This structure realizes the dynamic adjustment of the contact area between the heat sink and the reflector, thereby accurately controlling the heat dissipation efficiency and solving the problem of the fixed contact state of the traditional heat dissipation structure leading to a single heat dissipation effect.

[0020] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0023] like Figures 1-2As shown, a reflector that enhances heat dissipation performance includes a conical reflector 2 disposed inside a housing 1. A heat dissipation plate 3 is disposed on the back of the reflector 2. The heat dissipation plate 3 is inclined and the inclination direction is parallel to the generatrix of the reflector 2. The inner and outer sidewalls of the heat dissipation plate 3 are arc surfaces. The inner sidewall of the heat dissipation plate 3 can contact the back of the reflector 2. When the inner sidewall of the heat dissipation plate 3 is not in contact with the reflector 2, the vertical distance between the inner sidewall of the heat dissipation plate 3 and the reflector 2 decreases from the middle of the heat dissipation plate 3 to the left and right sides. The housing 1 is also provided with an adjustment mechanism 4 that drives the heat dissipation plate 3 to move closer to or further away from the reflector 2. The heat dissipation plate 3 is also provided with a heat transfer structure.

[0024] In this invention, the reflector features an inclined heat dissipation plate with curved sidewalls on its back, the inclination direction of which is parallel to the reflector's generatrix. An adjustment mechanism moves the heat dissipation plate closer to or further away from the reflector, adjusting the contact area between the heat dissipation plate and the reflector. Combined with the heat transfer structure within the heat dissipation plate, flexible adjustment of heat dissipation performance is achieved. When the heat dissipation plate is not in contact with the reflector, it does not deform. At this time, the vertical distance between the inner sidewall of the heat dissipation plate and the reflector decreases from the center to the sides. The adjustment mechanism moves the heat dissipation plate to contact the reflector, causing deformation. By controlling the distance, the contact area between the heat dissipation plate and the reflector can be adjusted to meet different heat dissipation needs, effectively solving the problems of traditional reflectors lacking heat dissipation function or having unadjustable heat dissipation effects.

[0025] Specifically, the adjustment mechanism 4 includes a connecting plate 5 fixed in the middle of the outer wall of the heat sink 3. The connecting line between the connecting plate 5 and the heat sink 3 is parallel to the generatrix of the reflector 2. The connecting plate 5 is vertically arranged and its top end is fixedly connected to the connecting plate mounting plate 6. The housing 1 is also provided with at least two drivers 7. The output shaft of the driver 7 is fixedly connected to the connecting plate mounting plate 6 and can drive the connecting plate mounting plate 6 to reciprocate along the axial direction of the reflector 2. After the driver 7 drives the heat sink 3 to move downward until the left and right sides of the heat sink 3 contact the reflector 2, the force generated by the driver 7 when it continues to drive the heat sink 3 to move downward can cooperate with the back of the reflector 2 to compress the heat sink 3. After the heat sink 3 is compressed and deformed, the heat sink 3 can gradually contact the back of the reflector 2 from the sides to the middle. The adjustment mechanism, through the cooperation of the connecting plate, the mounting plate of the connecting plate and the driver, drives the heat sink to move along the axis of the reflector. When the heat sink moves down to the sides and contacts the reflector, the continuous force of the driver can squeeze the heat sink to deform it, and gradually contact the back of the reflector from the sides to the middle. This structure realizes the dynamic adjustment of the contact area between the heat sink and the reflector, thereby accurately controlling the heat dissipation efficiency and solving the problem of the fixed contact state of the traditional heat dissipation structure leading to a single heat dissipation effect.

[0026] Specifically, driver 7 is a linear motor.

[0027] Specifically, the driver 7 is fixed to the top of the inner wall of the housing 1, and a heat shield 8 is provided on the outside of the driver 7. The housing 1 is also provided with heat dissipation holes that connect the inner cavity of the heat shield 8 to the outside. The driver is fixed to the top of the inner wall of the housing, and a heat shield is provided on the outside. The heat dissipation holes on the housing connect the heat shield to the outside, which can effectively prevent the heat generated by the driver during operation from interfering with the heat dissipation of the reflector. At the same time, the heat of the driver itself can be dissipated in time through the heat dissipation holes, ensuring the stability of the adjustment mechanism and avoiding additional heat from affecting the overall heat dissipation performance of the reflector.

[0028] Specifically, the heat transfer structure includes a heat dissipation channel 9 disposed inside the heat sink 3. The connecting plate 5 has symmetrically arranged end plates 10 on both sides of its connection point with the heat sink 3. Each end plate 10 has a connection hole 15 connected to the heat dissipation channel 9, and the outer end of the connection hole 15 is connected to a flexible heat dissipation hose 11 for connecting air-cooled or water-cooled equipment. The heat transfer structure efficiently transfers heat from the reflector through the heat dissipation channel inside the heat sink, combined with the connection hole on the end plate and the flexible heat dissipation hose for connecting air-cooled or water-cooled equipment. This design expands the heat dissipation methods, enhances heat dissipation capacity, and solves the problem of low efficiency when relying solely on natural heat dissipation.

[0029] Specifically, the mounting plate 6 of the connecting plate also has an annular input channel 12 and an output channel 13. The outer end of the heat dissipation hose 11 for inputting the cooling medium, which is connected to the connection hole 15, is uniformly connected to the input channel 12, and the outer end of the heat dissipation hose 11 for outputting the cooling medium, which is connected to the connection hole 15, is uniformly connected to the output channel 13. The annular input and output channels in the mounting plate of the connecting plate uniformly connect the heat dissipation hoses for inputting and outputting the cooling medium, making the cooling medium flow path regular and evenly distributed, improving heat transfer efficiency, and simplifying the pipeline connection structure for easy maintenance.

[0030] Specifically, the connecting plate mounting plate 6 has an annular cross-section, and a central hole 16 corresponding to the lamp mounting hole on the reflector 2 is provided at the center of the connecting plate mounting plate 6. The annular cross-section of the connecting plate mounting plate and the central hole corresponding to the lamp mounting hole do not affect the lamp installation, and can adapt to the structural layout of the reflector, ensuring that the adjustment mechanism works in coordination with the reflector and the lamp, and avoiding structural interference that affects the heat dissipation and adjustment effect.

[0031] Specifically, the reflector 2 has three heat dissipation plates 3 on its back, and these three heat dissipation plates 3 are distributed circumferentially along the axis of the reflector 2. The three heat dissipation plates distributed circumferentially along the axis of the back of the reflector can cover the back of the reflector in all directions, so that the heat is evenly distributed, the overall heat dissipation effect is enhanced, the local high temperature accumulation is avoided, and the problem of uneven heat dissipation caused by incomplete coverage in traditional heat dissipation structures is solved.

[0032] Specifically, the bottom outer wall of the reflector 2 is provided with several reflector fixing plates 14 with bolt holes along the circumferential direction. The reflector 2 is fixed inside the housing 1 by the reflector fixing plates 14. The reflector fixing plates provided circumferentially along the bottom outer wall of the reflector fix the reflector inside the housing by bolt holes, so that the reflector is installed firmly and the positional displacement caused by vibration during operation is avoided, which would affect the cooperation between the heat sink and the reflector, thus ensuring stable heat dissipation performance.

[0033] Specifically, the heat sink 3 is made of a thermally conductive material with deformation recovery properties. The heat sink, made of a thermally conductive material with deformation recovery properties, can deform smoothly and contact the reflector when compressed, and can return to its original shape after the external force is removed. This ensures that the contact state between the heat sink and the reflector can be flexibly changed with the adjustment mechanism. At the same time, the good thermal conductivity enhances heat transfer efficiency and improves the heat dissipation effect.

[0034] Specifically, thermally conductive materials with deformation recovery properties can be thermally conductive elastic alloys such as nickel-titanium alloys (shape memory alloys), copper-based elastic alloys (such as copper-beryllium alloys), thermally conductive silicone composite materials such as silicone materials filled with metal powders (such as silver powder, copper powder) or carbon fibers, or thermally conductive elastomers (thermoplastic elastomer TPE / TPU composite materials) such as thermoplastic elastomers filled with graphene or aluminum powder. In practical applications, the selection can be made by comprehensively considering the operating temperature, heat dissipation requirements, cost, and thermally conductive medium.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
