At present, the heat dissipation of electronic products mainly depends on heat dissipation fins, wherein the fin heat dissipation fins are mainly in a heat dissipation fin form, and the working principle of the heat dissipation fins is that the heat dissipation area is enlarged through the fins, and the heat conduction speed is improved through arranging a ventilation channel. Therefore, it can be seen that the heat dissipation area of the fins and the ventilation performance of the surfaces of the fins are the key to determine whether the fin fins can achieve good heat dissipation effect.

However, the design concept of the fin heat sink in the prior art is limited, and the ventilation effect on the surface of the fins depends on the gaps or channels between the fins, which results in poor heat dissipation effect.

Detailed Description

The following description is of the preferred embodiment of the present invention only, and is not intended to limit the scope of the present invention, which is to be accorded the widest scope consistent with the principles and spirit of the present invention.

As shown in fig. 1 to 4, in an embodiment, a wind-gathering duct type fin heat sink includes a bottom plate 1, a mounting structure for mounting an electronic component is disposed on a lower surface of the bottom plate 1, a plurality of fins 2 are vertically distributed on an upper surface of the

bottom plate

1, 1 or more wind-gathering tube structures 201 are disposed on the fins 2, an axis of each wind-gathering tube structure 201 is parallel to front and rear end surfaces of each fin 2, and the fins are uniformly distributed on the upper surface of the bottom plate; in this embodiment, 1 or more wind gathering pipe structures 201 are arranged on the fins 2, and in the heat dissipation process, the wind gathering pipe structures 201 are heated, the air pressure in the wind gathering pipe structures is reduced, and the external low-temperature air can be attracted to flow through the pipes rapidly, so that the heat dissipation efficiency of the fins 2 is greatly increased, the wind gathering pipe is based on the principle of wind gathering by a narrow pipe, and the wind gathering pipe can be arranged to be a longer tubular structure.

In a further embodiment, as shown in fig. 1, the fins 2 are distributed on the upper surface of the base plate in a matrix, the fins 2 are parallel to each other, and the adjacent wind collecting pipe structures 201 in the same row are opposite end to end; in this way, air can freely pass through the inter-row channels, the inter-column channels and the inclined channels formed by the fins 2, and the heat dissipation efficiency is further improved.

In a further embodiment, 3 wind gathering pipe structures 201 are arranged on the fin 2.

In a further embodiment, as shown in fig. 2 or 3, 1 wind collecting pipe structure 201 is provided on the fin 2, and the 1 wind collecting pipe structure 201 is provided in the middle of the fin 2.

In a further embodiment, as shown in fig. 2 or 3, the inner diameter of one end of the wind gathering pipe structure 201 is larger than that of the other end, and the small inner diameter end and the large inner diameter end of the adjacent wind gathering pipe structure 201 in the same row are opposite; referring to fig. 1, since the small inner diameter end and the large inner diameter end of the adjacent wind collecting pipe structures 201 in the same row are opposite to each other, serial airflow in the same row can be formed, which is beneficial to further improving the heat dissipation efficiency.
