Embodiment 1
[0022] like figure 1 and figure 2 As shown, an active heat sink with omni-directional convection, which includes a heat dissipation body and a heat transfer component, the heat transfer component is at least partially penetrated inside the heat dissipation body, and forms an integral body with the heat dissipation body, the heat dissipation The heat dissipation channel is provided on the main body, and the heat dissipation main body includes a first heat dissipation fin group 5 and a second heat dissipation fin group 6, and the first heat dissipation fin group 5 and the second heat dissipation fin group 6 are provided with heat dissipation channels , the extension direction of the heat dissipation channel of the first heat dissipation fin group 5 and the extension direction of the heat dissipation channel of the second heat dissipation fin group 6 are staggered. This design makes all-round convection around the radiator, so that the hot air flow can flow in all directions, s...
Embodiment 2
[0029] This embodiment is similar to Embodiment 1, the difference is that the installation method between the heat transfer substrate 7 and the heat dissipation body is different. The top of the first cooling fin group 5 is provided with a concave position 9 for installing the object to be radiated, the top plane of the second cooling fin group 6 is flush with the bottom surface of the concave position 9, and the heat transfer The substrate 7 is fixed on the plane formed by the top plane of the second heat dissipation fin group 6 and the bottom surface of the recess 9, and part of the heat transfer substrate 7 is embedded in the first heat dissipation fin from both sides of the recess 9 Inside the group 5, a third heat dissipation fin group 10 is respectively provided at both ends above the heat transfer substrate 7 corresponding to the top plane of the second heat dissipation fin group 6, preferably, the third heat dissipation fin group The heat dissipation channel direction ...
Embodiment 3
[0031] like image 3 As shown, a stage lamp includes a light source module 3, a heat sink 2 with the same structure as that of embodiment 1, several lamp function modules and a housing 1, the light source module 3, radiator 2, and each lamp function module They are all arranged inside the housing 1 , the functional modules of the lamps are arranged in the light path in front of the light source module 3 , and the heat sink 2 surrounds the periphery and the bottom of the light source module 3 from below the light source module 3 . The radiator 2 is provided with a cooling channel, and the top of the radiator 2 is provided with a concave position 9 , and the light source module 3 is arranged in the concave position 9 . The housing 1 is provided with heat dissipation holes 4 corresponding to the heat dissipation channels of the radiator 2 around.
