Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0046] Referring to Figure 1 , Figure 2 and Figure 5 , an embodiment of the present application provides a liquid cooling system 100 for cooling and heat dissipation of light emitting elements 300 in a lamp 1000, which comprises a cooling module 10, a liquid cooling device 20 and a connecting pipeline 30.

[0047] The cooling module 10 comprises a cooling housing 11, and the cooling housing 11 is internally provided with a cooling cavity 110 for cooling liquid to flow through. The surface of the cooling housing 11 has a cooling surface 1101 and a connecting surface 1102 which are independent of each other, the cooling surface 1101 is used to connect the light emitting elements 300 of the lamp 1000, and the connecting surface 1102 is provided with an inlet 1103 and an outlet 1104 which are in communication with the cooling cavity 110.

[0048] The liquid cooling device 20 is externally arranged on the light emitting elements 300, and the liquid cooling device 20 comprises a liquid cooling tank 21 and a refrigeration component 22 arranged corresponding to the liquid cooling tank 21. The liquid cooling tank 21 is internally provided with a containing cavity for cooling liquid to flow through, and the refrigeration component 22 is used to cool the cooling liquid inside the liquid cooling tank 21, so that the cooling liquid with higher temperature enters the containing cavity through the inlet of the liquid cooling tank 21, and the cooling liquid with lower temperature after being cooled by the refrigeration component 22 flows out through the outlet of the liquid cooling tank 21.

[0049] The connecting pipeline 30 is connected between the cooling module 10 and the liquid cooling device 20, and the connecting pipeline 30 comprises an inlet pipe 31 and an outlet pipe 32. The inlet of the inlet pipe 31 is in communication with the outlet of the liquid cooling tank 21, and the outlet of the inlet pipe 31 is communicated with the inlet 1103 of the cooling module 10. The inlet of the outlet pipe 32 is communicated with the outlet 1104 of the cooling module 10, and the outlet of the outlet pipe 32 is in communication with the inlet of the liquid cooling tank 21.

[0050] For the liquid cooling system 100 of the present application, the cooling module 10 and the liquid cooling device 20 are connected through the connecting pipeline 30, which can be externally arranged at the light emitting area of the lamp 1000, so as to effectively simplify the structure of the light emitting area of the lamp 1000 and effectively reduce the overall weight of the light emitting area of the lamp 1000. The power setting and installation form of the lamp 1000 are no longer limited by the heat dissipation structure arranged inside the lamp shell 200 in the prior art. The liquid cooling device 20 arranged externally to the light emitting element 300 can improve the heat dissipation efficiency according to the high power setting of the light emitting element 300, so as to ensure the heat dissipation effect of the high power lamp 1000, and also realize the lightweight design of the light emitting area of the lamp 1000, so that the lamp 1000 can be flexibly transported and installed for use, and the user's experience is effectively improved.

[0051] As shown in Figures 2 to 4 In some embodiments of the present application, the cooling shell 11 includes a bottom plate 111 and a cover plate 112 connected to the bottom plate 111, and the bottom plate 111 is provided with a receiving groove 1110. The cover plate 112 is connected to the groove opening of the bottom plate 111 corresponding to the receiving groove 1110, and the cover plate 112 and the bottom plate 111 form a cooling cavity 110.

[0052] The outer surface of the cover plate 112 constitutes a cooling surface 1101, which is used to fix the light emitting element 300 to dissipate heat and cool the light emitting element 300. The outer surface of the bottom plate 111 away from the cover plate 112 constitutes a connecting surface 1102, and the connecting surface 1102 is provided with an inlet 1103 and an outlet 1104, so as to realize the circulation of the cooling liquid in the cooling cavity 110.

[0053] In some examples, the cooling module 10 further includes a flow guide plate 12 arranged in the receiving groove 1110. The flow guide plate 12 is provided with a through hole 120, and the through hole 120 is arranged corresponding to the inlet 1103. The cooling liquid can enter the cooling cavity 110 through the inlet 1103 and the through hole 120, and flow out from the outlet 1104 after being guided by the flow guide plate 12, so as to take away the heat generated by the light emitting element 300 fixed on the cover plate 112, thereby cooling and dissipating heat of the light emitting element 300.

[0054] The flow guide plate 12 is arranged in the receiving groove 1110 of the bottom plate 111, which is used to guide the cooling liquid entering the inlet 1103, so that the cooling liquid can flow uniformly to each position of the cooling cavity 110, and the complex buffer flow limiting structure is no longer needed inside the cooling cavity 110. Not only can the overall structure of the cooling module 10 be simplified, but also the heat dissipation efficiency of the cooling module 10 can be improved.

[0055] In some examples, the guide plate 12 is provided with a guide groove 121 which is in communication with the through hole 120, and the extension direction of the guide groove 121 is consistent with the extension direction of the line connecting the liquid outlet 1104 and the liquid inlet 1103.

[0056] This arrangement can enable the guide groove 121 to be arranged on both sides of the through hole 120 of the guide plate 12, so that when the cooling liquid enters the through hole 120 through the liquid inlet 1103, it can be quickly guided into the guide groove 121 and flow along the extension direction of the guide groove 121, thereby effectively ensuring that the cooling liquid can be uniformly distributed in the cooling cavity 110.

[0057] In some embodiments of the present application, the cooling module 10 can further include fins 13. The fins 13 are arranged on the inner side surface of the cover plate 112, and the extension direction of the fins 13 is perpendicular to the extension direction of the guide groove 121.

[0058] The fins 13 extend towards the guide plate 12 and extend into the cooling cavity 110. The inner side surface of the cover plate 112 is spaced apart and provided with a plurality of fins 13, and the space between the adjacent two fins 13 forms a heat dissipation channel for the flow of cooling liquid. The cooling liquid flows in the heat dissipation channel, which can achieve rapid heat dissipation and cooling of the light emitting element 300.

[0059] In some examples, the side wall of the guide plate 12 and the inner side wall of the containing groove 1110 of the bottom plate 111 are spaced apart from each other and form a backflow channel. After passing through the heat dissipation channel between the adjacent fins 13, the cooling liquid can flow out of the liquid outlet 1104 through the backflow channel.

[0060] In some examples, the area of the guide plate 12 can be smaller than the area of the containing groove 1110 of the bottom plate 111, so that when the guide plate 12 is fixed in the containing groove 1110, there is a space between the peripheral side wall of the guide plate 12 and the inner wall of the containing groove 1110, and this space forms a backflow channel for the cooling liquid.

[0061] The backflow channel surrounds the peripheral side of the guide plate 12, and the liquid outlet 1104 is arranged corresponding to the backflow channel. When the cooling liquid enters the cooling cavity 110 from the liquid inlet 1103, it can flow through the through hole 120 on the guide plate 12 and then enter the guide groove 121. Subsequently, the cooling liquid can flow along the guide groove 121 and pass through the heat dissipation channel between the fins 13. When the cooling liquid flows through the heat dissipation channel, it can exchange heat with the fins 13 to absorb the heat on the fins 13. The cooling liquid which has exchanged heat with the fins 13 can finally enter the liquid outlet 1104 through the backflow channel and then flow out of the cooling housing 11 through the liquid outlet 1104.

[0062] In some embodiments of the present application, the cooling module 10 can further comprise a buffer 14, which is in a mesh structure. The buffer 14 is arranged between the deflector 12 and the cover plate 112, and the two side surfaces of the buffer 14 are in abutment with the fins 13 and the deflector 12 respectively.

[0063] In this embodiment, the surface of the deflector 12 facing the cover plate 112 can form a plurality of separated heat dissipation zones, each of which is provided with a buffer 14, and the plurality of buffers 14 are distributed on both sides of the deflection groove 121. When the cover plate 112 is connected to the bottom plate 111, the buffers 14 arranged on the deflector 12 can be in abutment with the end portions of the fins 13 on the cover plate 112 to prevent interference between the cover plate 112 and the deflector 12.

[0064] In some examples, the buffer 14 is provided with a plurality of spaced-apart buffer grooves 141, and the extension direction of the buffer grooves 141 is perpendicular to the extension direction of the deflection groove 121.

[0065] When the cover plate 112 is connected to the bottom plate 111, the buffer 14 is in abutment with the end portions of the fins 13. When the cooling liquid passes through the heat dissipation channel between adjacent fins 13, the buffer grooves 141 on the buffer 14 can make the cooling liquid completely fill the heat dissipation channel, so that the fins 13 can be completely immersed in the cooling liquid, thereby effectively improving the heat dissipation efficiency of the cooling module 10.

[0066] In addition, the cooling module 10 can further comprise a water inlet nozzle 15 and a water outlet nozzle 16. The water inlet nozzle 15 is arranged at the liquid inlet 1103 of the cooling shell 11, and the water outlet nozzle 16 is arranged at the liquid outlet 1104 of the cooling shell 11.

[0067] The water inlet nozzle 15 is used for detachable and quick docking with the outlet end of the liquid inlet pipe 31, and the water outlet nozzle 16 is used for detachable and quick docking with the inlet end of the liquid outlet pipe 32, so as to realize quick docking of the connecting pipeline 30 with the cooling module 10, and realize quick circulation of the cooling liquid in the cooling module 10 and the connecting pipeline 30.

[0068] Further, as shown in Figure 5 and Figure 6 In some embodiments of the present application, the liquid cooling device 20 is arranged outside the light emitting element 300, and the liquid cooling device 20 comprises a liquid cooling tank 21 and a refrigeration member 22 arranged corresponding to the liquid cooling tank 21.

[0069] The liquid cooling tank 21 is internally provided with a containing cavity for the flow of cooling liquid, and the refrigeration member 22 is used for cooling the cooling liquid in the liquid cooling tank 21, so that the cooling liquid with a relatively high temperature enters the containing cavity through the inlet of the liquid cooling tank 21, and is changed into cooling liquid with a relatively low temperature after being cooled by the refrigeration member 22 and then flows out through the outlet of the liquid cooling tank 21.

[0070] In some examples, the liquid cooling box 21 can include a first liquid box 211, a second liquid box 212, and a liquid guide box 213 connected between the first liquid box 211 and the second liquid box 212. The internal space of the first liquid box 211, the internal space of the liquid guide box 213, and the internal space of the second liquid box 212 are connected to form a containing cavity.

[0071] The inlet of the liquid cooling box 21 is arranged on the first liquid box 211, the outlet of the liquid cooling box 21 is arranged on the second liquid box 212, and the refrigeration device 22 is arranged corresponding to the liquid guide box 213. The first liquid box 211 can be arranged above the second liquid box 212 or below the second liquid box 212, as long as the liquid guide box 213 is connected between the first liquid box 211 and the second liquid box 212.

[0072] In this example, the first liquid box 211 and the second liquid box 212 are each provided with a slot 214 in communication with the internal space thereof. The liquid guide box 213 has a hollow structure with open ends, and a plurality of partitions can be arranged in the internal space of the liquid guide box 213 to form a plurality of channels in the internal space of the liquid guide box 213. The two ends of the liquid guide box 213 are respectively inserted and fixed in the slots 214 of the first liquid box 211 and the second liquid box 212 to realize the connection of the internal spaces of the first liquid box 211, the liquid guide box 213, and the second liquid box 212.

[0073] A plurality of liquid guide boxes 213 can be arranged, and the plurality of liquid guide boxes 213 are arranged in the length direction of the first liquid box 211 and the second liquid box 212.

[0074] In some examples, the refrigeration device 22 is a fan, which is fixed on one side of the liquid guide box 213 and arranged with the air outlet of the fan facing the liquid guide box 213. The fan can rapidly cool the cooling liquid flowing in the internal space of the liquid guide box 213, so that the cooling liquid entering the containing cavity through the inlet of the liquid cooling box 21 is cooled by the refrigeration device 22 and then flows out of the liquid cooling box 21 through the outlet as cooling liquid with a lower temperature. In other examples, the refrigeration device 22 can also be a semiconductor refrigeration piece, which can be directly fixed on the surface of the liquid guide box 213 to cool the cooling liquid flowing in the internal space of the liquid guide box 213.

[0075] In the example where the refrigeration device 22 is a fan, the liquid cooling box 21 can further include a ventilation device 23 arranged on the liquid guide box 213. The ventilation device 23 is arranged on each side of the liquid guide box 213, and the ventilation device 23 and the surface of the liquid guide box 213 form a plurality of air guide grooves 24, through which the cooling air generated by the refrigeration device 22 passes.

[0076] The air guide grooves 24 can make the cooling air generated by the refrigeration device 22 pass through the surface of the liquid guide box 213 uniformly and effectively, so that the cooling liquid flowing in the internal space of the liquid guide box 213 is rapidly cooled.

[0077] In some embodiments of the present application, asFigures 7 to 9 As shown, the liquid cooling device 20 can include a liquid cooling shell 25, and the liquid cooling tank 21 and the refrigerating element 22 can be fixed in the liquid cooling shell 25, and the refrigerating element 22 can be arranged inside the liquid cooling shell 25, and the side of the liquid cooling tank 21 away from the refrigerating element 22 can be provided corresponding to the side of the liquid cooling shell 25.

In the second liquid cooling tank 2102, the second liquid box 212 is arranged above the first liquid box 211, the second liquid box 212 is provided with the outlet of the second liquid cooling tank 2102, and the first liquid box 211 is provided with the inlet of the second liquid cooling tank 2102. The outlet of the first liquid cooling tank 2101 and the inlet of the second liquid cooling tank 2102 are in communication through the communication pipe 26.

[0082] Specifically, the liquid outlet 1104 of the cooling module 10 is in communication with the inlet of the first liquid cooling tank 2101 through the liquid outlet pipe 32, so that the cooling liquid with a relatively high temperature which has completed heat exchange with the light emitting element 300 in the cooling module 10 enters the first liquid box 211 of the first liquid cooling tank 2101, and enters the second liquid box 212 of the first liquid cooling tank 2101 through the refrigeration processing of the refrigerating element 22 when flowing through the liquid guide box 213 of the first liquid cooling tank 2101, so as to complete the first-stage refrigeration processing.

[0083] The coolant that has completed the primary refrigeration treatment in the first liquid cooling box 2101 can enter the first liquid box 211 of the second liquid cooling box 2102 through the connecting pipe 26, and when flowing through the liquid guide box 213 of the second liquid cooling box 2102, it enters the second liquid box 212 of the second liquid cooling box 2102 through the refrigeration treatment of the refrigeration component 22, thereby completing the secondary refrigeration treatment.

[0084] In this example, the outlet of the second liquid cooling box 2102 is connected to the liquid inlet 1103 of the cooling module 10 through the liquid inlet pipe 31, so that the coolant that has completed the secondary refrigeration treatment can enter the cooling cavity 110 of the cooling shell 11, thereby cooling and dissipating the heat of the light-emitting element 300 arranged on the cooling surface 1101 of the cooling shell 11.

[0085] It can be understood that when there are multiple liquid cooling boxes 21 in the liquid cooling device 20, the multiple liquid cooling boxes 21 can form a multi-stage refrigeration treatment for the coolant, thereby improving the cooling efficiency of the coolant.

[0086] In some embodiments of the present application, the liquid cooling device 20 may further include a liquid cooling outflow pipe 27 and a liquid cooling inflow pipe 28. One end of the liquid cooling outflow pipe 27 is connected to the outlet of the liquid cooling tank 21, and the other end of the liquid cooling outflow pipe 27 is used to connect to the inlet of the liquid inlet pipe 31. One end of the liquid cooling inflow pipe 28 is connected to the inlet of the liquid cooling tank 21, and the other end of the liquid cooling inflow pipe 28 is used to connect to the outlet of the liquid outlet pipe 32.

[0087] like Figure 10 As shown, the side of the liquid cooling housing 25 may be provided with openings for the liquid cooling outflow pipe 27 and the liquid cooling inflow pipe 28 to pass through. The opening for the liquid cooling outflow pipe 27 and the opening for the liquid cooling inflow pipe 28 may be independently provided on the liquid cooling housing 25, and the two openings may be a first opening 251 and a second opening 252, respectively.

[0088] In some examples, the inlet end of the liquid-cooling inlet pipe 28 is correspondingly disposed at the first opening 251, and when the outlet end of the liquid outlet pipe 32 is connected to the first opening 251, communication between the liquid outlet pipe 32 and the liquid-cooling inlet pipe 28 is achieved. The outlet end of the liquid-cooling outflow pipe 27 is correspondingly disposed at the second opening 252, and when the inlet end of the liquid inlet pipe 31 is connected to the second opening 252, communication between the liquid inlet pipe 31 and the liquid-cooling inlet pipe 28 is achieved.

[0089] In addition, the liquid cooling device 20 further includes a driving pump 29 . The driving pump 29 may be disposed on the liquid cooling outflow pipe 27 to pump the cooling liquid into the cooling module 10 .

[0090] In some embodiments of the present application, the outlet end of the liquid inlet pipe 31 is detachably connected to the liquid inlet 1103 of the cooling module 10 , and the inlet end of the liquid outlet pipe 32 is detachably connected to the liquid outlet 1104 of the cooling module 10 .

[0091] Such a configuration not only enables the cooling module 10 and the connecting pipeline 30 to be transported and carried separately, facilitating the use of the user, but also facilitates the maintenance of the liquid cooling system 100, enabling the cooling module 10 or the connecting pipeline 30 to be replaced independently, thereby facilitating the extension of the service life of the liquid cooling system 100 as a whole.

[0092] In some examples, the inlet end of the liquid inlet pipe 31 is detachably connected to the second through port 252 of the liquid cooling shell 25, and the outlet end of the liquid outlet pipe 32 is detachably connected to the first through port 251 of the liquid cooling shell 25, so as to achieve detachable connection between the inlet end of the liquid inlet pipe 31 and the outlet of the liquid cooling tank 21, and detachable connection between the outlet end of the liquid outlet pipe 32 and the inlet of the liquid cooling tank 21.

[0093] Such a configuration not only enables the liquid cooling device 20 and the connecting pipeline 30 to be transported and carried separately, facilitating the use of the user, but also facilitates the maintenance of the liquid cooling system 100, enabling the liquid cooling device 20 or the connecting pipeline 30 to be replaced independently, thereby facilitating the extension of the service life of the liquid cooling system 100 as a whole.

[0094] As shown in Figure 11 The embodiment of the present application also provides a lamp 1000, which comprises a lamp shell 200, a light emitting element 300 arranged on the lamp shell 200, and a liquid cooling system 100. The specific structure of the liquid cooling system 100 has been described above, and will not be described here.

[0095] The cooling module 10 is arranged inside the lamp shell 200, the light emitting element 300 is fixed on the cooling surface 1101 of the cooling module 10, and the lamp shell 200 is provided with a through port for connecting the liquid inlet pipe 31 and the liquid outlet pipe 32.

In this example, the light emitting element 300 can include a lamp panel and a plurality of lamp beads arranged on the lamp panel.

[0096] As shown in Figure 12 In some embodiments of the present application, the lamp 1000 further comprises a connecting bracket 600 for fixing the light emitting element 300 and the cooling module 10 on the lamp shell 200.

[0097] In other embodiments, the lamp 1000 can also not be provided with the lamp shell 200, and the light emitting element 300 can be directly fixed on the cooling module 10.

[0098] In some examples, the connecting bracket 600 is in the shape of a U.

The bottom leg portion of the connecting bracket 600 can be detachably connected to the inner wall of the lamp shell 200 to fix the light emitting element 300 and the cooling module 10 on the lamp shell 200.

[0099] In this example, the connecting bracket 600 can be made of copper material. The copper material has very high thermal conductivity, which can quickly conduct the heat of the light emitting element 300 to the cooling module 10, so that the cooling liquid circulating in the cooling module 10 can efficiently dissipate the heat of the light emitting element 300.

[0100] The cooling module 10 and the liquid cooling device 20 are connected by the connecting pipeline 30, which can be externally arranged on the light emitting element 300 to effectively simplify the structure of the light emitting area in the lamp 1000 and effectively reduce the overall weight of the light emitting area in the lamp 1000. The power setting and installation form of the lamp 1000 are no longer limited by the heat dissipation structure arranged inside the lamp shell 200 in the prior art. The liquid cooling device 20 arranged externally on the light emitting element 300 can correspondingly improve the heat dissipation efficiency according to the high-power setting of the light emitting element 300, so as to ensure the heat dissipation effect of the high-power lamp 1000 while realizing the lightweight design of the light emitting area in the lamp 1000. The lamp 1000 can be flexibly transported and installed for use, effectively improving the user experience.

The electric wire 500 can be connected to the electric interface arranged on the liquid cooling shell 25 and the lamp shell 200, respectively, to realize the electrical connection between the control device 400 and the light emitting element 300 and the liquid cooling device 20.

[0102] The electric interface on the liquid cooling device 20 can also be connected to an external power supply device, such as a power socket, to realize the power supply of the driving pump 29 and the refrigeration element 22 by the external power supply device. The control device 400 is electrically connected to the light emitting element 300, which can realize high-power light emission of the light emitting element 300 and control the working state and working parameters of multiple lamp beads in the light emitting element 300.
