Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a heat dissipation device for industrial and mining lamps. Background Technology

[0002] Industrial and mining lamps are industrial lighting fixtures mainly used in high-altitude locations such as factories and gas stations. Because these lamps typically have high power ratings, generally above 200W, they generate a significant amount of heat during operation. If this heat is not dissipated in a timely manner, it can reduce the lamp's lifespan or even cause it to be completely damaged.

[0003] Existing traditional industrial and mining lamps generally adopt an integrated structure, which concentrates heat. If the heat dissipation is poor, it will affect the service life and make them prone to failure, thus causing risks to production operations. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation device for industrial and mining lamps to solve the problems mentioned in the background art.

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

[0006] A heat dissipation device for industrial and mining lamps, comprising:

[0007] A hollow, square frame, the frame of which is made of bent strips of wood;

[0008] Several elongated heat dissipation modules are arranged in a linear array within the square frame along its length, with gaps between each module to form a continuous heat dissipation airflow channel. Each heat dissipation module is an integrally extruded aluminum profile, including an elongated convex-shaped base, multiple heat dissipation fins integrally formed on the base, and a mounting groove on the bottom surface of the base for mounting a light source module. The front and rear ends of the base are detachably connected to the inner side of the square frame.

[0009] The control box has connecting plates at both ends; the connecting plates are detachably connected to the inner side of the square frame; the control box is suspended above the square frame via the connecting plates;

[0010] The U-shaped mounting bracket has its two ends hinged to the outer wall of the square frame.

[0011] Preferably, the square frame is formed by splicing together two first frames extending along the length direction and two second frames extending along the width direction.

[0012] Preferably, the first frame has a U-shaped structure, and the second frame has a straight structure; the two ends of the second frame are threadedly connected to the folded edges at the two ends of the U-shaped structure of the first frame.

[0013] Preferably, a plurality of first mounting holes and wiring holes are arrayed along the length of the first frame, and the wiring holes facilitate the connection of the light source module extending from both ends of the base to the control box for electrical connection; the front and rear ends of the base of the heat dissipation module are threadedly connected to the first mounting holes.

[0014] The second frame has a second mounting hole arrayed along its width direction, and the connecting plate is threadedly connected to the second mounting hole.

[0015] Preferably, the connecting part of the U-shaped mounting bracket is provided with a hinge seat, which is threadedly connected to the outer wall of the second frame by bolts.

[0016] Preferably, the heat dissipation fins include bottom fins located on both sides of the bottom of the base and extending horizontally outward, top side fins located on both sides of the top of the base and extending horizontally outward, and a central fin located on the top surface of the base and extending vertically upward.

[0017] Compared with the prior art, the heat dissipation device for industrial and mining lamps of this application has the following advantages:

[0018] 1. High-efficiency heat dissipation and temperature control: By arranging multiple elongated heat dissipation modules in a linear array within a square frame, and forming a through-flow heat dissipation channel between the modules, the heat dissipation surface area is effectively increased, promoting natural air convection and accelerating heat dissipation. The heat dissipation modules are made of one-piece extruded aluminum profiles with good thermal conductivity, which can quickly conduct the heat generated by the light source module to the heat dissipation fins, thereby reducing the overall operating temperature of the industrial lamp and extending the service life of the light source and electronic components.

[0019] 2. Modular design and convenient maintenance: The heat dissipation module, square frame, and control box all adopt a detachable connection structure, making assembly, disassembly, and maintenance more convenient. When a heat dissipation module or light source fails, it can be replaced individually without replacing the entire lamp, reducing maintenance costs and time.

[0020] 3. Thermal isolation and circuit protection: The control box is mounted on top of the square frame via a connecting plate, which prevents heat from being directly conducted from the heat dissipation device to the control box. This prevents the electronic components inside the control box from failing due to overheating, and improves the stability and safety of the circuit.

[0021] 4. Structural strength and installation flexibility: The square frame is made of bent long strips of board, making it lightweight yet sturdy, suitable for high-altitude locations. The U-shaped mounting bracket is hinged to the square frame, allowing for angle adjustment of the industrial and mining lamps to meet different lighting needs, while also simplifying installation.

[0022] 5. Uniform heat dissipation and improved reliability: The heat dissipation fins adopt a multi-directional design (including bottom fins, top side fins and central fins), which further increases the heat dissipation area, ensures uniform heat distribution and dissipation, reduces the risk of local overheating, thereby reducing the probability of failure caused by poor heat dissipation in industrial and mining lamps and improving their reliability in industrial environments.

[0023] In summary, this utility model effectively solves the problems of concentrated heat dissipation and low efficiency in traditional industrial and mining lamps by optimizing the heat dissipation structure, material selection, and modular design. It achieves good heat dissipation without the need for external fans or complex cooling systems, thereby improving the service life and safety of industrial and mining lamps.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Example 1

[0032] like Figure 1-6 As shown, this embodiment provides a heat dissipation device for industrial and mining lamps.

[0033] The heat dissipation device for this industrial and mining lamp includes a hollow frame-type square frame 1. The square frame 1 is composed of two first frame pieces 11 extending along the length direction and two second frame pieces 12 extending along the width direction, joined end-to-end. Specifically, the first frame pieces 11 have a U-shaped structure and are formed by bending long strips of board; the second frame pieces 12 have a straight-line structure. The two ends of the second frame pieces 12 are connected to the folded edges of the U-shaped structure of the first frame pieces 11 by bolts or threads.

[0034] Within the square frame 1, several elongated heat dissipation modules 2 are arranged in a linear array along its length. Gaps exist between each heat dissipation module 2, forming a continuous heat dissipation duct 3. Each heat dissipation module 2 is an integrally extruded aluminum profile, comprising an elongated convex-shaped base 21, multiple heat dissipation fins integrally formed on the base 21, and a mounting groove 24 on the bottom surface of the base 21 for mounting a light source module. The heat dissipation fins include bottom fins 22 extending horizontally outward from both sides of the bottom of the base 21, top side fins 25 extending horizontally outward from both sides of the top of the base 21, and a central fin 23 extending vertically upward from the top surface of the base 21.

[0035] The first frame 11 has a plurality of first mounting holes 111 arranged in an array along its length. The front and rear ends of the base 21 of the heat dissipation module 2 are threadedly connected to the corresponding first mounting holes 111 by bolts, thereby achieving detachable installation. The first frame 11 also has wiring holes 112 for power cords to pass through.

[0036] The device also includes a control box 4 with connecting plates 41 at both ends. The second frame 12 has second mounting holes 121 arranged in an array along its width. The connecting plates 41 are threadedly connected to the second mounting holes 121 by bolts, so that the control box 4 is suspended above the square frame 1. The wires electrically connected to the control box 4 can pass through the heat dissipation duct 3 and be led out from the wiring hole 112.

[0037] In addition, the device is equipped with a U-shaped mounting bracket 5 for mounting the entire mining lamp onto the support. The connecting parts at both ends of the U-shaped mounting bracket 5 are provided with hinge seats 51, which are threadedly connected to the outer wall of the second frame 12 by bolts to form a hinge, so that the illumination angle of the mining lamp can be adjusted.

[0038] Working principle: When the industrial lamp is working, the heat generated by the light source module is conducted to the base 21 of the heat dissipation module 2 and quickly diffuses to all the heat dissipation fins (bottom fins 22, top side fins 25, and central fins 23). Because the array arrangement of the heat dissipation modules 2 forms a through-flow heat dissipation channel 3, the heated air naturally forms convection, continuously carrying away the heat. The control box 4, being suspended, avoids direct impact from the heat below, ensuring the stable operation of its internal electronic components. Example 2

[0039] Another embodiment, based on Embodiment 1, demonstrates the advantages of a modular design for the heat dissipation device of an industrial and mining lamp in terms of maintenance.

[0040] Procedure for replacing heat dissipation module or light source

[0041] When the light source module on a heat dissipation module 2 is damaged or requires maintenance, it can be replaced by following these steps. The entire process does not require disassembling the entire industrial lamp:

[0042] 1. Power off: First, ensure that the power to the mining lamps is completely turned off to ensure safe operation.

[0043] 2. Disassemble the old module: Disconnect all electrical connections from the wiring hole 112 to the internal circuit. Then, using a screwdriver or other tools, loosen and remove the bolts that secure the front and rear ends of the heat dissipation module 2 to the first mounting hole 111 on the first frame 11. At this point, the connection between the heat dissipation module 2 and the square frame 1 is released.

[0044] 3. Remove the module: Gently pull the heat dissipation module 2 out of the square frame 1 along the horizontal direction so that it can be taken out through the heat dissipation air duct 3.

[0045] 4. Replace the light source (if necessary): If only the light source module is damaged, the light source module in the mounting slot 24 at the bottom of the heat dissipation module 2 after it has been pulled out can be easily replaced or repaired on the workbench.

[0046] 5. Install the new module: Push the replaced light source or the brand new heat dissipation module 2 horizontally into the square frame 1 along the heat dissipation air duct 3, so that the mounting holes at both ends of the base 21 are aligned with the first mounting holes 111 on the first frame 11.

[0047] 6. Fixing and Wiring: Use bolts to re-secure the heat dissipation module 2 to the first frame 11. Then, lead the power cord of the light source module on the heat dissipation module 2 out from the wiring hole 112 and connect it to the main circuit.

[0048] 7. Power restoration and testing: After completing all connections, restore power to the industrial lamps and test whether the replaced module works properly.

[0049] Procedure for replacing the control box

[0050] When control box 4 malfunctions, the replacement procedure is as follows:

[0051] 1. Power off: Similarly, first ensure that the power to the industrial and mining lamps is completely cut off.

[0052] 2. Disconnect: Open the cover of control box 4 and disconnect all electrical connections between it and the internal circuitry.

[0053] 3. Disassemble the control box: Use tools to loosen and remove the bolts that fix the connecting plates 41 on both sides of the control box 4 to the second mounting holes 121 on the second frame 12.

[0054] 4. Remove the control box: Lift the control box 4 upwards and remove it from above the square frame 1.

[0055] 5. Install the new control box: Place the new control box 4 on top of the square frame 1, aligning the holes on the connecting plates 41 on both sides with the second mounting holes 121 on the second frame 12.

[0056] 6. Fixing and Wiring: Secure the connecting plate 41 to the second frame 12 with bolts. Then, connect the main power supply line and drive output line, etc., to the corresponding terminals inside the new control box 4 as specified.

[0057] 7. Power restoration and testing: Close the control box cover, restore power, and test whether the industrial and mining lamp functions have returned to normal.

[0058] The modular design of this invention makes both the heat dissipation module 2 and the control box 4 independent and detachable components. During maintenance, operators do not need to remove the entire light fixture from a height; they only need to replace the faulty module, greatly simplifying the maintenance process, shortening maintenance time, and reducing the risks and costs of working at heights.
