Description

Technical Field

[0001] This utility model belongs to the field of tri-proof lamp technology, and more specifically, it relates to a tri-proof lamp driver heat dissipation device. Background Technology

[0002] The rugged lamp driver is a core electronic component designed specifically for rugged lamps. Its core function is to convert the conventional AC power input from the mains into the stable DC power required by the rugged lamp light source. The heat dissipation performance of the rugged lamp driver is a key design feature to ensure the long-term stable operation of high-power rugged lamp drivers in harsh environments such as outdoor spaces, factory workshops, basements, and chemical workshops, where there is moisture, dust, and corrosive gases. Most existing rugged lamp drivers rely on passive heat dissipation by using a casing made of metal materials with high thermal conductivity.

[0003] The existing application number is CN201920452754.9. This utility model discloses a heat dissipation device for a tri-proof lamp driver, including a driver fixing plate (1), a driver (2), a spring plate (3), a fixing plate (4), an electrical plate (5), and a lamp housing assembly (6). In this utility model, the driver and the driver fixing plate are connected to the electrical plate through a spring plate. When the electrical plate is inserted, the spring plate pushes the driver against the top of the lamp housing assembly, and the heat of the driver is dissipated through the lamp housing assembly, thereby increasing the life of the electrical components.

[0004] Based on the above, the tri-proof lamp driver relies solely on the passive heat dissipation of the high thermal conductivity metal casing. Some high-power tri-proof lamps generate a lot of heat. Although this can ensure safe use, the high heat will still have a significant impact on the lifespan of the controller and the lamp body. After the driver fails, it is mostly connected to the tri-proof lamp back plate by bolts, which is inconvenient to disassemble and assemble. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a heat dissipation device for a tri-proof lamp driver. This addresses the issue that existing tri-proof lamp drivers rely solely on passive heat dissipation through a high thermal conductivity metal casing. Some high-power tri-proof lamps generate significant heat, which, while ensuring safety, can still negatively impact the lifespan of the controller and the lamp body. Furthermore, when the driver malfunctions, it is often connected to the tri-proof lamp's backplate via bolts, making disassembly and reassembly inconvenient.

[0006] The purpose and effect of this utility model's heat dissipation device for a tri-proof lamp driver are achieved through the following specific technical means:

[0007] A heat dissipation device for a tri-proof lamp driver includes a metal backplate, a lampshade, a driver, a lamp body, a fixing block, a wiring channel, a snap-fit ​​plate, an auxiliary heat dissipation component, and an installation limiting component. The lampshade is fixedly connected to the bottom of the metal backplate. The driver is disposed inside the metal backplate. The lamp body is fixedly connected to the bottom of the driver. The fixing block is fixedly connected to the inside of the metal backplate. The wiring channel is formed on the top of the fixing block. The snap-fit ​​plate is fixedly connected to the right side of the driver. The auxiliary heat dissipation component is disposed inside and on the left side of the metal backplate. The installation limiting component is disposed inside the fixing block.

[0008] Furthermore, the auxiliary heat dissipation component includes: a receiving groove and a thermally conductive silicone pad; the receiving groove is formed on the top of the driver; the thermally conductive silicone pad is placed inside the receiving groove.

[0009] Furthermore, the auxiliary heat dissipation assembly also includes: a water-cooled heat pipe, a fixed bracket, and a heat exchange module; the water-cooled heat pipe is fixedly connected to the outside of the driver; the right end of the fixed bracket is fixedly connected to the left side of the metal back plate; the heat exchange module is fixedly connected to the left side of the fixed bracket, and the heat exchange module is fixedly connected to the outer end of the water-cooled heat pipe.

[0010] Furthermore, the installation limiting component includes a sliding plate and an operating plate; the sliding plate is slidably connected inside the fixed block; and the operating plate is fixedly connected to the right side of the sliding plate.

[0011] Furthermore, the installation restriction component also includes: a right positioning plate and a positioning groove; the right positioning plate is fixedly connected to the left side of the operation panel; the positioning groove is opened inside the snap-fit ​​plate, and the right positioning plate is inserted into the positioning groove.

[0012] Furthermore, the installation restriction assembly also includes: a reset spring and a left positioning plate; the right end of the reset spring is fixedly connected to the left side of the operation panel, and the left end of the reset spring is fixedly connected to the inside of the fixing block; the left positioning plate is fixedly connected to the top of the metal back plate, and the left positioning plate is in contact with the left side of the driver.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, the thermally conductive silicone pad in the slot at the top of the driver can quickly transfer heat from the top of the driver to the metal backplate. Furthermore, the heat conduction can be further enhanced by applying thermal paste to eliminate gaps. The water-cooled heat pipe on the outside of the driver, together with the heat exchange module, can actively assist in heat dissipation around the driver when needed, significantly reducing the overall temperature of the driver and extending its service life.

[0015] Secondly, when it is necessary to replace the thermal conductive silicone pad, reapply thermal paste, or repair the driver, simply pull the operating plate to the right to easily remove the driver downwards. After maintenance, pull the operating plate again and align the left end of the driver with the left positioning plate before moving it upwards. After releasing the operating plate, the driver can be fixed in place. The entire process requires no complicated tools, is highly efficient, and ensures the continuous effectiveness of the heat dissipation structure.

[0016] This invention utilizes a thermally conductive silicone pad, combined with an external water-cooled heat pipe and heat exchange module, to achieve active auxiliary heat dissipation, significantly reducing the overall temperature of the driver and extending its service life. Furthermore, when replacing the thermally conductive silicone pad, applying thermal paste, or repairing the driver, the driver can be easily removed by simply pulling the control panel to the right. This simple and efficient operation, combining efficient heat dissipation with convenient maintenance, makes it more stable and adaptable to harsh environments such as outdoor spaces and factory workshops, which are humid and dusty. This further ensures the long-term reliable operation of the tri-proof light driver and maintains good heat dissipation performance. Attached Figure Description
