As shown in fig. 1 to 2, a novel water-cooled LED driving power supply includes: a power supply housing 1; a fin type water-cooling radiator 2 is arranged in the power supply shell 1; the fin type water-cooling radiator 2 consists of a radiator main body 3 and a radiating plate 4; the top of the radiator main body 3 is sunken to form a groove, the radiating plate 4 is embedded and covered at the opening of the groove, and the radiating plate 4 is connected with the radiator main body 3 in a fitting way to form a sealed cavity; the radiator main body 3 is provided with a water inlet 5 and a water outlet 6, the water inlet 5 and the water outlet 6 are respectively positioned at two ends of the bottom of the radiator main body 3, and the water inlet 5 and the water outlet 6 are both communicated with the sealed cavity; the bottom downwardly extending protrusion of heating panel 4 is provided with a plurality of fins 7, and the bottom butt of fin 7 and the bottom butt of recess divide into a plurality of runners 8 with sealed cavity, and the rivers divide into a plurality of runners 8 under the separation of fin 7 when water inlet 5 intakes, and rivers flow in runner 8 inside between fin 7 under the effect of water pressure, and rivers take away the heat of control circuit board 9 through heat transfer to flow from the delivery port 6 of radiator main part 3 other end. The fin type water-cooling radiator 2 is added in the power supply shell 1, the flowing liquid is matched with the fins 7 made of metal to replace air as a heat transfer medium, and the control circuit board 9 is subjected to heat dissipation, so that the integral use energy consumption is reduced, and the accumulation of internal heat is reduced; the design of the fins 7 divides the sealed cavity into a plurality of flow channels 8, the number of the fins 7 is designed according to the requirement, the number of the fins 7 is generally three to nine, the increase of the number of the fins 7 can enable the cross section area of a single flow channel 8 to be smaller and smaller, the flow channels 8 are smaller and smaller so that water flow is relatively less, the flow speed of the water flow is faster and faster, the turbulence degree of the water flow is severe, and the heat dissipation efficiency is improved; the fin type water-cooled radiator 2 generates less noise when in operation relative to a cooling fan, and has lower dependence on the environment.

In this embodiment, as shown in fig. 3, three fins 7 are provided, and because the water flow mode of the fin-type water-cooled radiator 2 is unidirectional water flow, the water flow path is single, the water temperature is continuously increased along with the water flow, so that the water temperature near the water outlet 6 is higher than the water temperature near the water inlet 5, and the water temperature gradually increases, so that the heat dissipation effect of the control circuit board 9 arranged near the water outlet 6 is gradually reduced; in order to solve the above problems, the flow channels 8 between the fins 7 are provided with turbulence columns 10 which are not equidistantly arranged, and the distance between the turbulence columns 10 is smaller as the turbulence columns 10 are closer to the water outlet 6; the turbulent flow column 10 is cylindrical, and heat exchange near the turbulent flow column 10 is increased through the turbulent flow column 10, so that the problem of uneven front and back heat dissipation of the heat dissipation plate caused by overhigh water temperature is solved.

Because the flow channel 8 is narrowed due to the arrangement of the turbulent flow column 10, the momentum loss of the fluid is increased after the turbulent flow column 10 collides with the turbulent flow column, namely, the larger water pressure is needed, namely, the larger working power of the micropump 12 is needed, in the embodiment, seven fins 7 are arranged, and compared with other fins 7 and three fins 7 in the aspects of temperature uniformity, junction temperature and pressure difference control, the fins 7 are more reasonable, and the water pressure is not needed to be larger than the turbulent flow column 10.

Wherein a heat conduction silicone grease layer 11 is arranged between the control circuit board 9 and the fin type water-cooling radiator 2. The heat generated by the electronic components on the control circuit board 9 during operation is firstly dispersed to the copper-clad substrate with larger area through fixed soldering tin, then the copper-clad substrate passes through the heat conduction silicone grease layer 11, the heat conduction silicone grease layer 11 not only bonds the control circuit board 9 and the fin type water-cooling radiator 2 together, but also fills up a tiny gap between the two, so that larger contact thermal resistance is prevented from being generated, and finally, the heat flows to the fin type water-cooling radiator 2, and most of the heat is taken away by the fin type water-cooling radiator 2 and is dissipated to the external environment.

Wherein, radiator main body 3 and heating panel 4 are aluminium goods.

As shown in fig. 4, the water inlet 5 and the water outlet 6 are both protruding from the bottom of the radiator main body 3, the water inlet 5 is connected to the micropump 12, the water outlet 6 is connected to the cooling device 13, and water flows into the fin type water-cooled radiator 2 under the driving action of the micropump 12 to bring the heat generated by the control circuit board 9 back to the cooling device 13 for cooling through the liquid flow, so that the next cycle is started.
