[0001] This utility model relates to the technical field of camera light cooling equipment, and in particular to a liquid cooling box and liquid cooling system. Background Technology

[0002] During film and television shooting, high-power lighting systems are typically required to meet the demand for illumination brightness. However, high-power lighting fixtures generate a lot of heat during operation. If heat is not dissipated in time, it may cause the internal components of the fixture to overheat, affecting the lifespan and stability of the equipment.

[0003] Traditional heat dissipation methods typically integrate heat dissipation devices, such as built-in fans, inside the lamp fixture and provide ventilation holes on the top of the fixture housing to expel internal heat. However, this method of integrating the heat dissipation device inside the lamp fixture and providing ventilation holes on the housing can easily allow moisture to seep into the fixture, potentially causing short circuits or component damage, thus reducing heat dissipation efficiency and affecting the normal operation of the lamp.

[0009] In some embodiments of this application, the flow guide plate has a plurality of first baffles in its flow channel; the first baffles extend along the length direction of the flow guide plate, and the plurality of first baffles are arranged at intervals along the width direction of the flow guide plate to divide the flow channel into a plurality of flow channels.

[0010] In some embodiments of this application, the fin unit includes a second partition, which is disposed inside the first liquid collection box and divides the internal space of the liquid collection box; the liquid inlet and liquid outlet of the radiator module are respectively disposed on both sides of the second partition of the first liquid collection box.

Detailed Implementation

[0032] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Traditional high-power video lights typically use built-in fans to dissipate heat from inside the light. These lights usually have ventilation holes on their outer casing to allow the fan to expel hot air. However, in rainy or snowy weather, rainwater or snowflakes can easily enter the light through these ventilation holes, causing short circuits and damage to internal components.

[0036] Therefore, please refer to Figures 1 to 13 This embodiment provides a liquid cooling system 100, which includes a photographic lamp 20 and a liquid cooling box 10. The photographic lamp 20 has a cooling module inside, and the liquid cooling box 10 is placed outside the photographic lamp 20; and is connected to the cooling module of the photographic lamp 20 to form a circulation pipeline, so that the liquid cooling box 10 can cool the components inside the photographic lamp 20.

[0037] Specifically, the photographic light 20 contains a light-emitting element and a cooling module. The light-emitting element emits photographic light. The cooling module is attached to the back of the light-emitting element to remove the heat generated by it. The cooling module has a condensation channel for coolant to pass through. When the coolant passes through the cooling module, it exchanges heat with the light-emitting element to remove heat. The coolant enters the liquid cooling tank 10 through an external water pipe 40 connected to the liquid cooling tank 10. After being cooled by the liquid cooling tank 10, it flows back to the photographic light 20 through another external water pipe 40, thus achieving cyclic cooling of the light-emitting element on the photographic light 20.

[0038] By placing the liquid cooling box 10 outside the photography lamp 20 and using the liquid cooling box 10 for heat dissipation and cooling, the photography lamp 20 does not need to have heat dissipation holes, effectively preventing moisture and other substances from entering the interior of the photography lamp 20, and ensuring that the photography lamp 20 maintains a stable temperature environment when operating at high power for a long time.

[0039] Please see Figure 1 In some embodiments, the liquid cooling system 100 further includes a control box 30, which is electrically connected to the photographic lamp 20 and the liquid cooling box 10 respectively to control the working status of the photographic lamp 20 and the liquid cooling box 10.

[0040] Specifically, the housing 11 of the liquid cooling box 10 is provided with an electrical connection port 113. The control box 30 is electrically connected to the photographic lamp 20 and the electrical connection port 113 of the liquid cooling box 10 via two cables 50, enabling the control box 30 to supply power to the electrical components inside the photographic lamp 20 and the liquid cooling box 10, and to coordinate the working status of the photographic lamp 20 and the liquid cooling box 10. The control box 30 contains an integrated circuit control module, which can adjust parameters such as brightness, color temperature, and flash mode of the photographic lamp 20 according to a preset program or user input signal, and simultaneously monitor the temperature status of the photographic lamp 20 in real time, and control the operating power of the liquid cooling box 10 according to temperature changes to achieve dynamic heat dissipation management.

[0041] For example, when the photography light 20 is in high-brightness mode for an extended period, the control box 30 will automatically increase the circulation speed of the coolant after detecting a temperature rise, thereby improving heat dissipation and preventing the light body from overheating and causing light decay or damage. The control box 30 can also intelligently adjust the operating mode of the liquid cooling box 10 according to factors such as ambient temperature and photography requirements, so that the heat dissipation efficiency matches the light output requirements, achieving energy-saving effects.

[0042] Please see Figures 2 to 5 In some embodiments, the liquid cooling box 10 includes a housing 11, a cooling radiator module 12, and a booster pump 13.

[0043] The housing 11 has a liquid inlet 111 and a liquid outlet 112, which are used to connect with the photographic lamp 20 to form a circulation loop. A radiator module 12 is disposed inside the housing 11; the radiator module 12 has a liquid inlet 12112 and a liquid outlet 12113, with the liquid inlet 12112 connected to the liquid inlet 111 on the housing 11. Coolant from the photographic lamp 20 enters the radiator module 12 through the liquid inlet 111 and undergoes heat exchange within the radiator module 12, thus cooling the coolant. A booster pump 13 is disposed inside the housing 11. The booster pump 13 is connected to both the liquid outlet 12113 of the radiator module 12 and the liquid outlet 112 on the housing 11; it pressurizes the coolant cooled by the radiator module 12, causing the coolant to flow back into the photographic lamp 20 through the liquid outlet 112.

[0044] Specifically, the shell 11 of the liquid cooling box 10 can be a cubic structure, with an internal cavity. The shell 11 of the liquid cooling box 10 has honeycomb holes communicating with the cavity, which can be used to quickly dissipate heat from the liquid cooling box 10. An inlet 111 and an outlet 112 can be provided on the side or top surface of the shell 11; the inlet 111 and outlet 112 can be connected to the cooling module inside the photographic lamp 20 via two external water pipes 40 to form a circulation pipeline.

[0045] After the coolant absorbs heat inside the camera lamp 20, it enters the radiator module 12 in the liquid cooling box 10 through the inlet 111 for heat exchange. After releasing heat in the radiator module 12, it is pressurized by the booster pump 13 and flows back to the camera lamp 20 through the outlet 112 on the housing 11 to complete the cyclic cooling process.

[0046] Please see Figure 4 In some embodiments, the booster pump 13 may be a centrifugal pump, gear pump or plunger pump, which pressurizes the liquid in the pump body through a centrifugal module, gear module or plunger module so that the coolant can overcome flow resistance or gravity and be smoothly delivered to the inside of the photographic lamp 20.

[0047] In some embodiments, the booster pump 13 can be connected to the power connection port 113 on the housing 11 via a cable, so that when the control box 30 is electrically connected to the liquid cooling box 10, the control box 30 can adjust the operating parameters of the booster pump 13, such as flow rate and pressure, according to the heat dissipation requirements of the photographic lamp 20, so that it can adapt to the heat dissipation requirements of the photographic lamp 20.

[0048] It is conceivable that in some embodiments, the radiator module 12 can employ different heat dissipation technologies, such as using high thermal conductivity materials to form heat pipes, using semiconductor cooling chips for heat exchange, or integrating an air-cooling auxiliary system for heat dissipation. Different types of coolant can also be selected, such as oil-based coolant or water-based coolant, to adapt to different usage requirements and environments.

[0049] Please see Figure 5 and Figure 6 In some embodiments, the liquid cooling box 10 includes a base 14 disposed inside the housing 11, and the radiator module 12 and the booster pump 13 are vertically fixed on the base 14. As an example, the booster pump 13 is a centrifugal pump, and the impeller shaft inside the centrifugal pump rotates in the vertical direction.

[0050] Specifically, the base 14 is fixed inside the housing 11 of the liquid cooling box 10. The base 14 includes a base plate 141 and a back plate 142. The base plate 141 has four support feet for supporting and fixing it. The booster pump 13 is vertically mounted on the base plate 141 and is fixed to the back plate 142 on the base 14 by two brackets 15 to secure the booster pump 13 to the base 14. In some other embodiments, rubber pads or elastic support feet may be provided on the base plate 141 to reduce vibration and noise during operation of the booster pump 13 and improve user comfort.

[0051] The back plate 142 of the base 14 is provided with an opening 143 corresponding to the radiator module 12. When the radiator module 12 is vertically fixed on the base 14, the opening 143 on the back plate 142 is directly facing the radiator module 12, which prevents the back plate 142 from blocking the radiator module 12 and allows the radiator module 12 to be directly exposed to the air circulation area, which helps to dissipate heat quickly and avoids the accumulation of heat inside the radiator module 12, which affects the heat dissipation performance.

[0052] Please see Figure 5 In some embodiments, the radiator module 12 includes a finned unit 121 and a cooling fan 122. The finned unit 121 has a fluid channel and a cooling duct, the fluid channel communicating with a liquid inlet 12112 and a liquid outlet 12113. The cooling duct is positioned relative to the fluid channel, and the cooling fan 122 is located on one side of the finned unit 121; the cooling fan 122 is used to generate airflow, which passes through the cooling duct to cool the coolant within the fluid channel.

[0053] The fluid channel has a liquid inlet 12112 connected to the liquid inlet 111 on the housing 11. When the high-temperature coolant passes through the fluid channel, the heat it carries is transferred to the outside through the channel wall. The cooling duct is positioned relative to the fluid channel to ensure that the heat transferred to the channel wall is quickly carried away by the airflow within the cooling duct. The cooling fan 122 is installed on one side of the finned unit 121. Its function is to generate convective airflow, causing air to flow along the cooling duct and carry away the heat from the fluid channel, thereby accelerating the cooling process of the coolant.

[0054] In some embodiments, multiple cooling fans 122 can be provided according to usage requirements, and the multiple cooling fans 122 can be electrically connected to the control box 30. The control box 30 can dynamically adjust the fan speed of the cooling fans 122 according to the heat dissipation requirements of the photographic light 20, so that the fan speed is reduced to reduce noise when the photographic light 20 is running under low load, and the fan speed is increased to enhance the heat dissipation effect when running under high load.

[0055] Please see Figures 7 to 9In some embodiments, the fin unit 121 includes a first liquid collection box 1211, a second liquid collection box 1212, and a guide plate 1213. The first liquid collection box 1211 and the second liquid collection box 1212 have multiple spaced-apart docking grooves 12111 on their opposite sidewalls. Both ends of the guide plate 1213 are respectively inserted into the docking grooves 12111 of the first liquid collection box 1211 and the second liquid collection box 1212. The guide plate 1213 has a guide channel 12131 extending along its length, which connects the interiors of the first liquid collection box 1211 and the second liquid collection box 1212 to form a fluid channel.

[0056] Specifically, a first liquid collection box 1211 is located at the bottom of a guide plate 1213, and a second liquid collection box 1212 is located at the top of a guide plate 1213. Multiple guide plates 1213 are provided between the first liquid collection box 1211 and the second liquid collection box 1212. These guide plates 1213 are spaced apart along the length of the liquid collection box, and both ends of each guide plate 1213 are connected to mating grooves 12111 on the first liquid collection box 1211 and the second liquid collection box 1212. The mating grooves 12111 can fix the guide plates 1213, allowing the multiple guide plates 1213 to be stably and periodically installed between the liquid collection boxes. The guide plate 1213 is a plate-shaped structure with openings at both ends and a hollow interior. The hollow interior forms a flow channel 12131, which extends along the length of the guide plate 1213. The flow channel 12131 connects the interior of the first liquid collection box 1211 and the second liquid collection box 1212, so that the coolant can be evenly distributed along the set flow path and complete heat exchange.

[0057] In some embodiments, the airflow generated by the cooling fan 122 can pass through the gap between two adjacent air deflectors 1213 to carry away the heat of the coolant within the air deflectors 1213. The air deflectors 1213 may be made of a high thermal conductivity metal (such as aluminum alloy or copper) to further enhance the heat exchange effect.

[0058] Please see Figures 8 to 12 In some embodiments, the fin unit 121 further includes a plurality of fin plates 1214. The fin plates 1214 are disposed between the intervals of two adjacent guide plates 1213 and abut against the outer surface of the guide plates 1213. The fin plates 1214 and the outer surface of the guide plates 1213 enclose a plurality of mutually spaced heat dissipation channels; the heat dissipation channels intersect the extending direction of the guide channel 12131.

[0059] Specifically, each fin plate 1214 is composed of concave and convex structures connected along its length, making the cross-section of the fin plate 1214 resemble a square wave. The concave structures on the fin plate 1214 form ventilation slots 12141, and multiple ventilation slots 12141 are spaced apart along the length of the fin plate 1214; the protruding structures on the fin plate 1214 are used to abut against the sidewall of the guide plate 1213, thereby increasing the heat dissipation area of ​​the sidewall of the guide plate 1213 in contact with the air, thus improving the heat exchange efficiency.

[0060] When the finned plate 1214 is positioned between two adjacent guide plates 1213, the sidewall of the guide plate 1213 will enclose the ventilation slot 12141 on the finned plate 1214 to form a heat dissipation airflow channel. The extending direction of the heat dissipation airflow channel is perpendicular to the guide channel 12131 within the guide plate 1213. The airflow generated by the cooling fan 122 passes through the heat dissipation airflow channel formed by the finned plate 1214 and the guide plate 1213, thereby rapidly cooling the coolant within the guide plate 1213.

[0061] Please see Figure 11 In some embodiments, the flow channel 12131 of the flow guide plate 1213 is provided with a plurality of first partitions 12132. The first partitions 12132 extend along the length direction of the flow guide plate 1213, and the plurality of first partitions 12132 are arranged at intervals along the width direction of the flow guide plate 1213 to separate the flow channel 12131.

[0062] Specifically, the first baffle 12132 extends along the length of the guide plate 1213 and is spaced apart in the width direction, thereby dividing a single flow channel 12131 into multiple independent flow channels. The arrangement of the first baffle 12132 effectively guides the coolant, ensuring uniform distribution of coolant within the guide plate 1213. Compared to a single large-channel structure, it can more effectively improve heat exchange performance. The shape of the first baffle 12132 can be either straight or corrugated to adapt to different application requirements.

[0063] Please see Figure 8 and Figure 9 In some embodiments, the finned unit 121 includes a second partition 1215, which is disposed inside the first liquid collection box 1211 and divides the internal space of the liquid collection box. The liquid inlet 12112 and the liquid outlet 12113 of the radiator module 12 are respectively disposed on both sides of the partition of the first liquid collection box 1211.

[0064] Specifically, a first liquid collection box 1211 is located at the bottom of the guide plate 1213. A second partition 1215 divides the internal space of the first liquid collection box 1211 into two independent areas. A liquid inlet 12112 and a liquid outlet 12113 connect the two independent areas on both sides of the second partition 1215 of the first liquid collection box 1211. At this time, the coolant in the guide plate 1213, which is connected to the liquid inlet 12112 area, flows from bottom to top into the second liquid collection box 1212. The coolant in the guide plate 1213, which is connected to the liquid outlet 12113 area, flows from top to bottom.

[0065] like Figure 4 As shown, the coolant in the guide plate 1213 on the right side of the second partition 1215 flows from bottom to top into the second condensate box 1212. After passing through the second condensate box 1212, the coolant flows back from the guide plate 1213 on the left side of the second partition 1215 to the first condensate box 1211. The entire fluid channel is inverted U-shaped, meaning the coolant flows in an inverted U-shape within the finned unit 121. This design effectively increases the flow path of the coolant within the finned unit 121, increases the residence time of the coolant within the finned unit 121, and effectively improves cooling efficiency.

[0066] Of course, in some other embodiments, the second partition 1215, the liquid inlet 12112 and the liquid outlet 12113 may also be disposed in the second liquid collection box 1212 on the top of the guide plate 1213, so that the fluid channels in the fin unit 121 are arranged in a U-shape.

[0067] Please see Figure 2 In some embodiments, the fin unit 121 further includes a side plate 1216. Both ends of the first liquid collection box 1211 and the second liquid collection box 1212 are provided with internally communicating openings. The side plate 1216 is fixedly connected to both ends of the first liquid collection box 1211 and the second liquid collection box 1212 and closes the openings of the first liquid collection box 1211 and the second liquid collection box 1212.

[0068] Specifically, the fin unit 121 is provided with two side plates 1216. The two side plates 1216 can be fixed to the two sides of the fin unit 121 by means of bolts or clips, so that the fin unit 121 forms an integral structure. The two ends of the side plates 1216 can abut against the openings of the end faces of the first liquid collection box 1211 and the second liquid collection box 1212 to seal the two ends of the first liquid collection box 1211 and the second liquid collection box 1212 and prevent liquid leakage.

[0069] Of course, in some other embodiments, the two ends of the first liquid collection box 1211 and the second liquid collection box 1212 can be set as closed ends.

[0070] Please see Figure 3 and Figure 5In some embodiments, the liquid cooling box 10 includes a connecting pipe 16 for connecting the cooling radiator module 12, the booster pump 13, and the liquid inlet 111 and liquid outlet 112 on the housing 11 to each other.

[0071] Specifically, the 16 connecting pipes include a first connecting pipe 161, a second connecting pipe 162, and a third connecting pipe 163. The first connecting pipe 161 connects the liquid inlet 111 on the housing 11 to the liquid inlet 12112 of the radiator module 12. The second connecting pipe 162 connects the liquid outlet 12113 of the radiator module 12 to the pump inlet 132 located on the lower middle side wall of the booster pump 13. The third connecting pipe 163 connects the pump outlet 131 at the top of the booster pump 13 to the liquid outlet 112 on the housing 11 to facilitate the passage of coolant.

[0072] Please see Figure 5 In some embodiments, adapters 164 may be provided on the first connecting pipe 161 and the third connecting pipe 163. The adapters 164 can connect the connecting pipes 16 by means of threaded connection, quick-connect fitting or flange connection, so that the user can quickly adjust the position of the inlet and outlet, and the installation position of the inlet 111 and the outlet 112 can be selectively switched between the top surface or the side surface of the housing 11 to adapt to the needs of different installation environments and coolant circulation paths.

[0073] In some embodiments, quick connectors 165 are connected to the inlet 111 and the outlet 112. The quick connectors 165 can quickly connect to the external water pipe 40 extending from the photographic lamp 20, so that the liquid cooling box 10 and the photographic lamp 20 can be quickly connected.

[0074] In summary, this application provides a liquid cooling box 10 and a liquid cooling system 100. By installing a radiator module 12 and a booster pump 13 inside the housing 11 of the liquid cooling box 10, the coolant inside the photographic lamp 20 can enter the radiator module 12 through the inlet 111 for efficient heat exchange, and then flow back into the photographic lamp 20 under the action of the booster pump 13, thereby forming a stable circulating cooling system. Compared with the traditional internal air cooling method, the heat exchange location of this application is located outside the photographic lamp 20. There is no need to open heat dissipation holes on the body of the photographic lamp 20, which effectively prevents moisture and other substances from entering the interior of the photographic lamp 20, and ensures that the photographic lamp 20 maintains a stable temperature environment during long-term high-power operation, thus extending the service life of the photographic lamp 20.
