The liquid cooling device 20 is externally arranged on the light emitting element 300, and the liquid cooling device 20 comprises a liquid cooling box 21 and a refrigerating piece 22 arranged corresponding to the liquid cooling box 21. The inside of the liquid cooling box 21 is provided with a containing cavity for cooling liquid to circulate, and the refrigerating piece 22 is used for cooling the cooling liquid in the liquid cooling box 21, so that the cooling liquid with higher temperature enters the containing cavity from the inlet of the liquid cooling box 21, and is converted into the cooling liquid with lower temperature after being cooled by the refrigerating piece 22, and flows out from the outlet of the liquid cooling box 21.
The connecting pipeline 30 is connected between the cooling module 10 and the liquid cooling device 20, and the connecting pipeline 30 comprises a liquid inlet pipe 31 and a liquid outlet pipe 32.

For the liquid cooling system 100 of the present application, the cooling module 10 and the liquid cooling device 20 are communicated through the connecting pipeline 30, so that the liquid cooling device and the connecting pipeline can be externally arranged in a light emitting area of the lamp, so as to effectively simplify a structural form of the light emitting area of the lamp 1000, effectively reduce the overall weight of the light emitting area of the lamp 1000, prevent the power setting and the mounting form of the lamp 1000 from being limited by a heat dissipating structure built in the lamp housing 200 in the prior art, and correspondingly improve the heat dissipating efficiency of the liquid cooling device 20 externally arranged on the light emitting element 300 according to the high power setting of the light emitting element 300, thereby ensuring the heat dissipating effect of the high power lamp 1000, and realizing the light weight design of the light emitting area of the lamp 1000, so that the lamp 1000 can be flexibly transported, mounted and used, and effectively improve the use experience of a user.
As shown in fig. 2 to 4, in some embodiments of the present application, the cooling housing 11 includes a base plate 111 and a cover plate 112 connected to the base plate 111, and a receiving groove 1110 is formed in the base plate 111. The cover plate 112 is connected to the bottom plate 111 at the notch of the corresponding accommodating groove 1110, and the cover plate 112 and the bottom plate 111 enclose to form a cooling cavity 110.
The outer surface of the cover plate 112 forms a cooling surface 1101 for fixing with the light emitting element 300 to perform heat dissipation cooling of the light emitting element 300. The outer surface of the bottom plate 111 facing away from the cover plate 112 forms a connection surface 1102, and a liquid inlet 1103 and a liquid outlet 1104 are formed, so that the circulation of cooling liquid in the cooling cavity 110 is realized.
In some examples, the cooling module 10 further includes a baffle 12, the baffle 12 being disposed in the receiving slot 1110. The baffle 12 is provided with a through hole 120 in a penetrating manner, and the through hole 120 is arranged corresponding to the liquid inlet 1103. The cooling liquid can enter the cooling cavity 110 through the liquid inlet 1103 and the through hole 120, and flow out of the liquid outlet 1104 after being drained 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 realizing cooling and heat dissipation of the light-emitting element 300.
The guide plate 12 is disposed in the accommodating groove 1110 of the bottom plate 111, and is used for guiding the cooling liquid entering the liquid inlet 1103, so that the cooling liquid can uniformly flow to each position of the cooling cavity 110, and the cooling cavity 110 does not need to use a complex buffering and current limiting structure, so that the overall structure of the cooling module 10 can be simplified, and the heat dissipation efficiency of the cooling module 10 can be improved.
In some examples, the baffle 12 is provided with a flow guiding groove 121 communicated with the through hole 120, and the extending direction of the flow guiding groove 121 is consistent with the extending direction of the connecting line of the liquid outlet 1104 and the liquid inlet 1103.
Such an arrangement can enable the diversion trench 121 to be disposed at both sides of the through hole 120 of the diversion plate 12, so that when the cooling liquid enters the through hole 120 through the liquid inlet 1103, the cooling liquid can be rapidly guided into the diversion trench 121 and flow along the extending direction of the diversion trench 121, thereby effectively ensuring that the cooling liquid can be uniformly distributed in the cooling cavity 110.
In some embodiments of the application, the cooling module 10 may further include fins 13. The fins 13 are disposed on the inner surface of the cover plate 112, and the extending direction of the fins 13 is perpendicular to the extending direction of the diversion trench 121.
The fins 13 extend toward the baffle plate 12 and extend into the cooling cavity 110, and a plurality of fins 13 are arranged on the inner side surface of the cover plate 112 at intervals, and the interval between two adjacent fins 13 forms a cooling channel for cooling liquid to circulate. The cooling liquid flows through the heat dissipation channel, and rapid heat dissipation and temperature reduction of the light emitting element 300 can be achieved.
In some examples, the side walls of the baffle 12 are spaced from the inner side walls of the receiving channel 1110 of the base plate 111 and form a return channel. After passing through the heat dissipation channels between the adjacent fins 13, the cooling liquid can flow out of the liquid outlet 1104 through the return channel.
Wherein the area of the baffle 12 may be smaller than the area of the receiving groove 1110 of the bottom plate 111 such that when the baffle 12 is fixed into the receiving groove 1110, a space is provided between the peripheral side wall of the baffle 12 and the inner wall of the receiving groove 1110, which forms a return passage for the cooling liquid to return.
The return channel surrounds the periphery of the baffle 12, and the liquid outlet 1104 is arranged corresponding to the return channel. After entering the cooling cavity 110 from the liquid inlet 1103, the cooling liquid can flow through the through holes 120 on the baffle 12, and thus enter the diversion trench 121. Subsequently, the cooling liquid can flow along the guide grooves 121 and pass through the heat dissipation channels between the fins 13. The cooling liquid is capable of heat exchange with the fins 13 while flowing through the heat dissipation channels to absorb heat on the fins 13. The cooling liquid after heat exchange with the fins 13 can finally enter the liquid outlet 1104 through the return passage, so that the cooling housing 11 flows out of the liquid outlet 1104.
In some embodiments of the present application, the cooling module 10 may further include a buffer 14, where the buffer 14 is a mesh structure. The buffer member 14 is disposed between the baffle 12 and the cover plate 112, and two side surfaces of the buffer member 14 are respectively abutted against the fins 13 and the baffle 12.
In this embodiment, the surface of the baffle 12 facing the cover plate 112 may form a plurality of separated heat dissipation areas, each heat dissipation area is correspondingly provided with a buffer member 14, and the plurality of buffer members 14 are distributed on two sides of the flow guiding groove 121. When the cover plate 112 is connected to the bottom plate 111, the buffer 14 provided on the baffle 12 can abut against the end portions of the fins 13 on the cover plate 112 to prevent the cover plate 112 from interfering with the baffle 12.
In some examples, the buffer member 14 is provided with a plurality of buffer grooves 141 arranged at intervals, and the extending direction of the buffer grooves 141 is perpendicular to the extending direction of the flow guide grooves 121.
When the cover plate 112 is attached to the bottom plate 111, the buffer 14 abuts against the end of the fin 13. When the cooling liquid passes through the heat dissipation channels between the adjacent fins 13, the buffer grooves 141 on the buffer member 14 can completely fill the heat dissipation channels with the cooling liquid, 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.
Furthermore, the cooling module 10 may also comprise a water inlet nozzle 15 and a water outlet nozzle 16. Wherein the water inlet 15 is arranged at the liquid inlet 1103 of the cooling shell 11, and the water outlet 16 is arranged at the liquid outlet 1104 of the cooling shell 11.
The water inlet nozzle 15 is used for being detachably and quickly abutted with the outlet end of the liquid inlet pipe 31, and the water outlet nozzle 16 is used for being detachably and quickly abutted with the inlet end of the liquid outlet pipe 32, so that the quick abutting of the connecting pipeline 30 and the cooling module 10 is realized, and the quick circulation conduction of cooling liquid in the cooling module 10 and the connecting pipeline 30 is realized.
