[0021] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0022] See also Figure 1-Figure 5 As shown, the LED light source of this embodiment includes an LED light source 200 and a water circulation refrigeration and heat dissipation device 100. The heat generated by the LED light source 200 when working can be quickly transferred through the water circulation refrigeration and heat dissipation device 100 to avoid brightness attenuation and life reduction of the LED light source 200 due to excessive temperature of the LED light source 200.

[0023] The water circulation refrigeration and heat dissipation device 100 includes a heat dissipation pipe 10, a circulating medium pump 20, a radiator 30 and a storage tank 40. The heat dissipation pipe 10, the circulating medium pump 20, the radiator 30 and the storage tank 40 are connected in sequence to form a circulation loop. The LED light source 200 contacts the heat dissipation pipe 10. Preferably, the heating surface of the LED light source 200 is as close to the heat dissipation pipe 10 as possible to improve the heat dissipation efficiency.

[0024] The storage tank 40 stores a heat dissipation medium, and the circulating medium pump 20 drives the heat dissipation medium to circulate along the circulation loop. It is understandable that the heat dissipation medium here can be a substance that can quickly exchange heat and cold, such as a coolant or a refrigerant, and the heat dissipation medium here can be in liquid or gaseous state. The circulating medium pump 20 provides power to drive the heat dissipation medium to circulate along the circulation loop.

[0025] Preferably, the first end of the heat pipe 10 is connected to the input end of the circulating medium pump 20 through the transmission pipe 104, the output end of the circulating medium pump 20 is connected to the input end of the radiator 30 through the transmission pipe 104, the output end of the radiator 30 is connected to the input end of the storage tank 40 through the transmission pipe 104, and the output end of the storage tank 40 is connected to the second end of the heat pipe 10.

[0026] Preferably, the water circulation refrigeration and heat dissipation device 100 further includes a plurality of quick-release connectors 50 for quickly accessing the transmission pipeline 104. The input and output ends of the circulating medium pump 20, the input and output ends of the radiator 30, and the input and output ends of the storage tank 40 are respectively installed with quick-release connectors 50. By providing the quick-release connectors 50, the transmission pipeline 104 can be quickly plugged in and out.

[0027] Preferably, the water circulation refrigeration and heat dissipation device 100 further includes a box 60, the circulating medium pump 20, the radiator 30 and the heat dissipation medium storage tank 40 are respectively installed in the box 60, and the heat dissipation pipe 10 is installed on the outer wall of the box 60. It can be understood that the circulating medium pump 20, the radiator 30 and the heat dissipation medium storage tank 40 are respectively installed in the box 60. At this time, the volume of the box 60 can be selected according to actual needs to meet the needs of miniaturization of the water circulation refrigeration and heat dissipation device 100.

[0028] Preferably, the water circulation refrigeration and heat dissipation device 100 further includes a first fixing member 70 and a second fixing member 80 , the circulating medium pump 20 is fixed in the box body 60 via the first fixing member 70 , and the storage tank 40 is fixed in the box body 60 via the second fixing member 80 .

[0029] Preferably, the water circulation refrigeration and heat dissipation device 100 also includes a water inlet interface 90 and a water outlet interface 101, which are respectively installed on the outer wall of the box body 60, and the first end of the heat dissipation pipe 10 is connected to one end of the water inlet interface 90, and the other end of the water inlet interface 90 is connected to the input end of the circulating medium pump 20 through the transmission pipe 104, and the second end of the heat dissipation pipe 10 is connected to one end of the water outlet interface 101, and the other end of the water outlet interface 101 is connected to the output end of the storage tank 40 through the transmission pipe 104.

[0030] It can be understood that since the water inlet interface 90 and the water outlet interface 101 are respectively installed on the outer wall of the box body 60, the heat dissipation pipe 10 respectively connected to the water inlet interface 90 and the water outlet interface 101 can be located outside the box body 60, so that the LED light source 200 located outside the box body 60 can be flexibly placed.

[0031] Preferably, the box body 60 is provided with an observation window 61 for observing the storage amount of the heat dissipation medium in the storage tank 40 and a liquid injection hole 62 for injecting the heat dissipation medium into the storage tank 40. Through the above arrangement, the user can more conveniently know the storage amount of the heat dissipation medium and effectively replenish the heat dissipation medium in the storage tank 40 outside the box body 60, which greatly improves the convenience of use.

[0032] Preferably, the water circulation refrigeration and heat dissipation device 100 further includes a heat dissipation fan 102, which is installed in the box body 60. The box body 60 is provided with an air outlet 63 and a heat dissipation port 64. The air outlet 63 corresponds to the heat dissipation fan 102, and the heat dissipation fan 102 is used to send the radiator 30 out of the box body 60 along the air outlet 63. By providing the heat dissipation fan 102, the air outlet 63 and the heat dissipation port 64, the heat dissipation efficiency of the water circulation refrigeration and heat dissipation device 100 is further improved by combining air cooling with liquid cooling.

[0033] Preferably, the water circulation refrigeration and heat dissipation device 100 further includes a handle 103 , which is mounted on the outer wall of the box body 60 . The handle 103 is provided to further enhance the portability of the water circulation refrigeration and heat dissipation device 100 .

[0034] It is understandable that in this embodiment, the water circulation refrigeration and heat dissipation device 100 is applied to the LED light source 200 to achieve rapid heat dissipation of the LED light source 200. Of course, the water circulation refrigeration and heat dissipation device 100 can also be applied to other objects that require rapid and continuous heat dissipation. The application occasions of the water circulation refrigeration and heat dissipation device 100 are not limited here. When the LED light source 200 is powered on, the circulating medium pump 20 and the cooling fan 102 can be powered on at the same time to achieve synchronous heat dissipation of the LED light source 200 when it is working. Of course, a temperature sensor can also be set for the LED light source 300, and the circulating medium pump 20 and the cooling fan 102 can be started to dissipate heat when the temperature of the LED light source 300 crosses a preset threshold, which will not be elaborated here.

[0035] Combination Figure 1-Figure 5 The heat dissipation pipe 10, the circulating medium pump 20, the radiator 30 and the storage tank 40 of the utility model are connected in sequence to form a circulation loop. The storage tank 40 stores the heat dissipation medium. The circulating medium pump 20 drives the heat dissipation medium to circulate along the circulation loop. The LED light source 200 contacts the heat dissipation pipe 10, and the circulating heat dissipation medium is used to quickly dissipate the heat of the LED light source 200, effectively avoiding the brightness attenuation and the reduction of the service life of the LED light source 200 caused by long-term overheating of the LED light source 200.
