Resin glue 4 is provided on the top of the heat column, and the resin glue is used to protect the heat column and seal one end of the heat column. The heat column passes through the heat sink and is connected to the heat sink by interference fit. The bottom of the heat column is sintered with the base, and the fan assembly is installed on the heat sink. The base absorbs heat and conducts heat to the heat column and the heat sink, and the heat is quickly dissipated under the action of the fan assembly.

[0028] In this embodiment, the heat sink is further configured with folded edges 21 on both sides, the cross section of the heat sink is U-shaped, the folded edges are perpendicular to the surface of the heat sink, and the connection between the folded edges and the heat sink is rounded.

[0029] In this embodiment, it is further configured that the distance between two adjacent heat sinks is consistent, the two adjacent heat sinks form an air duct 6, and a gap 7 is left between the folded edge and the adjacent heat sink. The configuration of the air duct and the gap can enable the heat sink to dissipate heat better.

[0030] In this embodiment, it is further configured that the fan assembly includes an outer frame 51 and a fan 52. The outer frame is installed on the side of the heat sink without a folded edge, and the fan is installed in the outer frame. A pair of fans are symmetrically arranged, and the fans face the air duct. The fans directly blow into the air duct formed by adjacent heat sinks, thereby improving the heat dissipation efficiency of the fans and the heat sink.

[0031] In this embodiment, it is further configured that holes 511 are provided at four corners of the outer frame, and the outer frame is connected to the heat sink through connecting rods passing through the holes, and the connecting rods are not drawn in the figure.

[0032] In this embodiment, it is further configured that the heat sink is provided with through holes with the same number as the heat columns, the through holes are of the same size, an annular surface 22 is provided at the through holes, the through holes are passed through by the corresponding heat columns, and the annular surface abuts against the outer wall of the heat column.

[0033] In this embodiment, it is further configured that the heat column is a copper heat column, the base is a copper base, and the heat sink is an aluminum heat sink. Copper has strong thermal conductivity efficiency and aluminum has strong heat dissipation capacity. The base and the heat column are both made of copper, so the heat conduction efficiency is high, and the contact area for heat absorption is increased through the base, and the heat dissipation of higher power products can be met through the aluminum heat sink.

[0034] Embodiment 2:

[0035] In this embodiment, if Figure 1-7 As shown, there are four heat columns, which are symmetrically installed on the base. The bottom of the heat columns are sintered to the base, and the side length of the base is much larger than 2 times the diameter of the heat columns. A single heat column and a single fan can meet the heat dissipation requirements of 1000W power products, and four heat columns and two fans can meet the heat dissipation requirements of 2500W power products.

[0036] The working principle of the multi-heat column dual-fan LED heat sink is that the base absorbs heat and conducts the heat to the heat columns and heat sinks, and the fan directly blows the air duct formed by adjacent heat sinks to improve the heat dissipation efficiency of the fan and heat sink.
