[0031] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0032] Combined with appendix Figure 1-11 A liquid cooling device based on all-weather miniaturized LED lamps includes a base 1, on which a lamp plate mounting bracket 2 is slidably disposed, and the lamp plate mounting bracket 2 is used to mount a lamp plate 3.

[0033] The lamp board 3 is a light-emitting element that can be installed and removed from the lamp board mounting bracket 2. The lamp board 3 has a multi-layer composite structure, consisting of an inner mating layer 31, a light source layer 32, a cooling layer 33, and a control layer 34 from the inside out.

[0034] Connecting pipes 311 are fixedly provided on both sides of the top of the inner side of the inner mating layer 31, and electrode connecting posts 312 are fixedly provided on both sides of the bottom of the inner side of the inner mating layer 31. The connecting pipes 311 are used to receive coolant, and the electrode connecting posts 312 are used to power the lamp board. An LED lamp core 321 is integrated on the light source layer 32. The LED lamp core 321 is composed of several LED beads, and a temperature sensor can also be set on the light source layer 32 to detect the temperature of the lamp board 3. An opening is provided on the inner mating layer 31, and the LED lamp core 321 is installed at the corresponding opening position of the inner mating layer 31, thereby exposing the LED lamp core 321.

[0035] The cooling layer 33 is closely attached to the light source layer 32. The cooling layer 33 is provided with cooling channels 331, which are preferably S-shaped to increase the contact area of ​​the coolant. Both ends of the cooling channels 331 are connected to the connecting pipes 311, so that the coolant introduced into the connecting pipes 331 flows through the path of the cooling channels 331. The coolant flows into the cooling channels 331 from the connecting pipes 311 on one side and flows out from the connecting pipes 311 on the other side, thereby cooling the entire cooling layer 33. The cooling layer 33 is made of a high thermal conductivity material. The cooling layer 33 exchanges heat with the LED lamp core 321 on the light source layer 32, which can quickly transfer the heat generated when the LED lamp core emits light to the coolant.

[0036] The control layer 34 is used to control the installation and removal of the lamp panel 3 on the lamp panel mounting bracket 2. A local space is provided within the control layer 34. A groove 341 is provided between the local space and the walls on both sides of the control layer 34. A locking slider 342 slides within the groove 341. Locking protrusions 343 are provided on both sides of the locking slider 342. The locking slider 342 extends into the local space. A control gear 345 is rotatably mounted within the local space. A rack that meshes with the control gear 345 is provided on the side of the locking slider 342 located within the local space. The locking sliders 342 on both sides are located on the local space. On the side and bottom, by rotating the control gear 345, the locking slider 342 located on the upper side slides to the lower side, and the locking slider 342 located on the lower side slides to the upper side. The locking slider 342 drives the locking protrusion 343 to move synchronously, thereby fixing the lamp panel 3 on the lamp panel mounting bracket 2. The control layer 34 is provided with a round hole to expose the outer surface of the control gear 345. A handle 346 is fixed on the outer surface of the control gear 345. The worker can change the position of the locking slider 342 by rotating the handle 346, thereby realizing the installation and disassembly of the lamp panel 3 on the lamp panel mounting bracket 2.

[0037] The lamp plate mounting bracket 2 includes a rectangular body 21. The inner side of the rectangular body 21 is provided with a lamp plate groove 22. The lamp plate groove 22 is used to install the lamp plate 3. The lamp plate 3 is snapped into the lamp plate groove 22. The lamp plate groove 22 is fixedly provided with mating plates 27 on both sides. The mating plates 27 are provided with mating grooves 271. The mating grooves 271 are correspondingly provided with engagement protrusions 343. The distance between the mating grooves 271 on the mating plate 27 on the same side at the same position is the same as the distance between the engagement protrusions 343 on the engagement slider 342 on the same side.

[0038] The end of the mating groove 271 has an opening on the mating plate 27 for entering the mating groove 271. The mating groove 271 is a groove that is inclined from the outside to the inside. The mating grooves 271 on the two sides of the mating plate 27 have different inclination directions. The mating groove 271 on one side is inclined upward from the outside to the inside, and the opening of the mating groove 271 on this side is located on the lower side. The mating groove 271 on the other side is inclined downward from the outside to the inside, and the opening of the mating groove 271 on this side is located on the upper side. The engaging protrusion 343 on the engaging slider 342 on the lower side engages into the mating groove 271 that is inclined upward from the bottom. The engaging protrusion 343 on the engaging slider 342 on the upper side engages into the mating groove 271 that is inclined downward from the top. The inner end of the mating groove 271 is set as a vertical groove path to facilitate locking the lamp plate 3.

[0039] Therefore, when installing the lamp panel 3, the worker rotates the control gear 345, which drives one side of the locking slider 342 to move upward and the other side to move downward. The locking protrusion 343 on the upward-moving locking slider 342 engages with the mating groove 271 that slopes upward from the outside to the inside. The locking protrusion 343 on the downward-moving locking slider 342 engages with the mating groove 271 that slopes downward from the outside to the inside. Thus, the lamp panel 3 moves towards the inside of the lamp panel mounting frame 2 by the inward movement of the locking protrusion 343. When the locking protrusion 343 reaches the vertical groove path at the end of the mating groove 271, it can maintain the engagement between the lamp panel 3 and the lamp panel mounting frame 2, thereby fixing the lamp panel 3 on the lamp panel mounting frame 2.

[0040] The rectangular body 21 is provided with a light channel 23 that is connected to the lamp plate groove 22. The light channel 23 passes through the rectangular body 21 and is correspondingly arranged with the LED lamp core 321. A lamp tube 24 is fixedly arranged on the outer surface of the rectangular body 21 and is correspondingly arranged with the light channel 23. The light emitted by the LED lamp core 321 on the lamp plate 3 passes through the light channel 23 and is emitted through the lamp tube 24.

[0041] The lamp tube 24 is provided with a plurality of heat dissipation fins 241 arranged sequentially and at equal intervals. The heat dissipation fins 241 are annular structures and fixedly installed on the outer surface of the lamp tube 241. The heat dissipation fins 241 can conduct heat out of the lamp tube 24, thereby reducing the temperature inside the lamp plate groove 22 and the lamp tube 24. A circular glass plate 242 is provided at the outer end of the lamp tube 24. The circular glass plate 242 can prevent dust from entering the lamp tube 24 and contaminating the lamp plate 3 installed in the lamp plate groove 22.

[0042] The upper sides of the rectangular body 21 are also provided with connection insertion ports 26. The connection insertion ports 26 extend through the rectangular body 21 to the outer surface of the rectangular body 21. The connection insertion ports 26 are correspondingly set with the connection pipes 311. When the lamp panel 3 is installed on the lamp panel mounting bracket 2, the connection pipes 311 are inserted into the connection insertion ports 26.

[0043] A pipe connector 27 is fixedly mounted on the outer surface of the rectangular main body 21. The pipe connector 27 can be fixed to the outer surface of the rectangular main body 21 with bolts. The pipe connector 27 contains two independent hollow spaces. The pipe connector 27 has two extension pipes 271 located on both sides. The two extension pipes 271 communicate with the hollow spaces on the same side of the pipe connector 27. The positions of the two extension pipes 271 correspond to the connection insertion ports 26 on the same side. The connection insertion ports 26 communicate with the extension pipes 271. The extension pipes 271 extend into the connection insertion ports 26. Thus, after the connection pipe 311 on the lamp panel 3 is inserted into the connection insertion port 26, the connection pipe 311 and the extension pipe 271 engage and communicate. The pipe connector 27 has flexible hose connection ports 272 on both sides. The two flexible hose connection ports 272 communicate with the hollow spaces on the same side.

[0044] The rectangular body 21 has electrode connection holes 28 on both sides of its lower inner side for insertion into electrode connection posts 312. The electrode connection posts 312 are correspondingly arranged and inserted into each other.

[0045] A sliding frame 4 is fixedly connected to the bottom of the lamp panel mounting bracket 2. The sliding frame 4 is used to support the movement of the lamp panel mounting bracket 2. Support legs 41 are provided on both sides of the bottom of the sliding frame 4. A movable slider 42 is fixedly provided at the bottom of the support legs 41. Movable slide rails 11 are fixedly provided on both sides of the base 1. The movable slider 42 slides on the slide rails 11. A lead screw 12 is also rotatably provided on the base 1. A threaded block 43 is provided at the bottom of the sliding frame 4. The threaded block 43 has a threaded hole. The threaded block 43 and the lead screw 12 form a lead screw engagement, so that the sliding frame 4 and the base 1 form a lead screw structure. The rotation of the lead screw 12 can drive the threaded block 43 to move, thereby synchronously driving the sliding frame 4 to move. The movement of the sliding frame 4 drives the lamp panel mounting bracket 2 to move. The movement of the lamp panel mounting bracket 2 can adjust the position of the lamp panel 3, thereby achieving the effect of adjusting the position of the light source. A motor 13 is fixedly provided on the base 1. A drive gear is provided on the output shaft of the motor 13. A driven gear meshing with the drive gear is provided on the lead screw 12. The rotation of the lead screw 13 is controlled by the motor 13. The motor 13 can be a stepper motor or a servo motor.

[0046] A battery 14 is fixedly installed inside the base 1. A drag chain 15 is provided between the end of the battery 14 and the lamp panel mounting bracket 2. A power cord is installed inside the drag chain 15, which can transfer the power of the battery 14 to the electrode connection hole 28. When the lamp panel 3 is installed on the lamp panel mounting bracket 2, the electrode connection post 312 is inserted into the electrode connection hole 28. At this time, the battery 14 is electrically connected to the LED lamp core 321, providing power for the lamp panel 3 to emit light. When the lamp panel mounting bracket 2 follows the sliding bracket 4, the power cord will not be disconnected from the lamp panel mounting bracket 2, thus maintaining a stable power supply.

[0047] The chassis 1 has heat exchangers 5 fixedly mounted on both sides. Each heat exchanger 5 has a fan 51 with a vent on its outer side. The vent is honeycomb-shaped to ensure maximum gas exchange. A circulation pump 6 is also fixedly mounted inside the chassis 1, positioned between the heat exchangers 5 on both sides of the chassis 1. The circulation pump 6 has hoses 7 on both sides that flow through the heat exchangers 5 and connect to hose connectors 272. A cooling pump 6 can be connected to the coolant circuit to further cool the coolant after it has absorbed heat and passed through the heat exchangers.

[0048] The hose 7 is filled with coolant, which is a propylene glycol aqueous solution and an insect repellent. Using propylene glycol aqueous solution and insect repellent as the base coolant meets the requirements for efficient heat dissipation. In extreme low-temperature environments, the mixing ratio of propylene glycol and water can be adjusted to lower the freezing point of the coolant, reaching -30℃ or even lower, ensuring low-temperature fluidity. The propylene glycol aqueous solution is chemically stable and has no significant corrosive effect on common metals and plastics. Simultaneously, the propylene glycol aqueous solution has low conductivity, meeting the electrical safety requirements of stage lights. The insect repellent acts as a bittering agent to avoid the risk of accidental ingestion. The coolant is environmentally friendly, pollution-free, readily available, and cost-effective.

[0049] Inside the heat exchanger 5, the coolant exchanges heat with the external environment. A temperature sensor near the LED chips intelligently controls the coolant flow rate of the circulating pump and the speed of the fan 51. Forced ventilation by the fan 51 within the heat exchanger 5 lowers its own temperature. The cooled coolant is then pumped back to the cooling pipes 331 of the cooling layer 33 of the lamp board 3 via the circulating pump 6. The cooling pipes 331 directly exchange heat with the light source layer 32, removing the heat generated during light emission. This cycle repeats continuously, achieving efficient and continuous heat dissipation for the LED chips. In low-temperature environments, the system can intelligently control and adjust the coolant flow rate and circulation speed to ensure efficient heat dissipation while preventing the coolant from freezing.

[0050] A control chip can be installed inside the base 1 or the light panel mounting bracket 2. The control chip contains a PID control algorithm, which automatically adjusts the speed of the circulating pump and the fan based on feedback data from the temperature sensor to control the coolant flow rate and temperature. At the same time, it dynamically adjusts the control parameters according to changes in ambient temperature to ensure that the system can operate efficiently in different environments.

[0051] The lamp board 3 is made of aluminum alloy, which has good thermal conductivity and is lightweight, enabling efficient heat dissipation while reducing the overall weight of the lamp. The lamp board 3 features an internal microchannel design; the channel width and depth are precisely calculated to ensure turbulent flow of the coolant within the channels, improving the convective heat transfer coefficient. An interdigitated channel layout ensures the coolant is evenly distributed across the surface of the lamp board 3, maximizing contact with the LED chip and effectively preventing localized overheating. Based on the internal structure of the lamp, the piping layout is optimized, minimizing pipe length and reducing the number of bends to lower coolant flow resistance.

[0052] Meanwhile, since coolant cannot be added during equipment shipping, the quick assembly and disassembly of the circulating pump 6, heat exchanger 5, and pipe connectors 27 to the pipeline adopts a sliding sleeve connection structure. Operators only need to align the joint with the circulating pump interface and push the sliding sleeve to complete the connection, eliminating the need for complex tightening or fixing operations, greatly improving installation and maintenance efficiency. A reliable anti-detachment fastening design is also incorporated to prevent the joint from loosening and falling off due to vibration, bumps, or other external forces during lamp operation. For example, a multi-stage locking structure is installed at the joint and circulating pump interface. When the joint is inserted, the locking mechanism automatically pops out and tightly locks the interface edge, providing strong axial and radial fastening force to ensure a stable connection and avoid the risk of coolant leakage.

[0053] In use, the lamp board 3 is installed on the lamp board mounting bracket 2. During installation, the connecting pipe 311 and electrode connecting post 312 on the lamp board 3 are inserted into the connecting insertion port 26 and electrode connecting hole 28 respectively. At the same time, the locking protrusion 343 on the lamp board 3 is locked into the opening of the mating slide groove 271. By manually turning the handle 346, the control gear 345 is driven to rotate, thereby moving the locking slider 342. In this way, the lamp board 3 is fixed in the lamp board mounting bracket 2 by the movement of the locking protrusion 343 in the mating slide groove 271.

[0054] When temperature control is required, the circulation pump 6 is turned on, and the coolant flows through the heat exchanger 5 to the pipe connector 27 through one side pipe, and then flows into the connecting pipe 311 through the hose connector 272. The coolant enters the cooling channel 331 through the connecting pipe 311 on the same side, flows through the entire cooling channel 331 and then flows out through the connecting pipe 311 on the other side. The outflowing coolant returns to the circulation pump 6 through the pipe connector 27 on the other side, through the heat exchanger 5 and the cooling pump.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
