Embodiment Construction
[0027] The first embodiment of the present invention is figure 1 and 2 As shown, it includes a plurality of cooling fins 1 and a tubular heat-absorbing core 2. The plurality of cooling fins 1 are arranged radially around the outer wall of the heat-absorbing core 2. Since each cooling fin 1 is arranged at intervals, adjacent cooling fins 1 There is a certain gap between them, which is defined as the main ventilation slot 11, wherein the cross section of the main ventilation slot 11 is U-shaped; in addition, the plurality of cooling fins 1 all extend to the same end of the heat-absorbing core 2, and This end forms a cavity for placing devices, the cavity is roughly bowl-shaped and communicates with multiple main ventilation slots 11 .
[0028] Furthermore, two radially arranged fins 3 are arranged on the outer side of each heat sink 1, and since the two fins 3 are arranged at intervals, there is a certain gap between the two fins 3, and the gap is defined as a secondary The ve...
