Technical Field

This novel electronic component fin technical field that belongs to, concretely relates to take fin of tuber pipe.

Background

When the electronic element works, part of electric energy is converted into heat energy. If the electronic element works in a high-temperature environment and does not have good heat dissipation, the efficiency of the electronic element is reduced, and the service life of the electronic element is shortened.

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.

However, the conventional fin heat sink has a drawback of low heat dissipation efficiency due to limitations of design considerations.

For overcoming prior art's not enough, the utility model discloses a take fin of tuber pipe, this fin are equipped with a plurality of heat dissipation mechanisms, and heat dissipation mechanism includes fin group and tuber pipe, and fin group includes a plurality of along the linear arrangement and highly increase gradually the fin, is equipped with the tuber pipe in fin group upper end, through the interior air current circulation that forms of tuber pipe, promotes the radiating efficiency and improves.

In order to realize the purpose, the novel technical scheme is as follows:

the utility model provides a take fin of tuber pipe, includes the bottom plate, bottom plate lower surface be equipped with the mounting structure who is used for installing electronic component, it has a plurality of heat dissipation mechanisms to distribute at the upper surface of bottom plate, heat dissipation mechanism include fin group and tuber pipe, fin group contain a plurality of along the linear arrangement and highly increase progressively in proper order the fin, there is the tuber pipe at the top integrated into one piece of fin group.

Preferably, the fins are arranged in parallel with each other.

Preferably, the inner diameter of the air pipe gradually increases from one end to the other end, and the end with the large inner diameter is positioned on one side of the fin with the lowest height.

Preferably, the top end of each fin is provided with an arc-shaped notch with different inner diameters, and the lower part of the outer wall surface of the air pipe is welded with the arc-shaped notch.

Preferably, the upper edge of the outer wall surface of the air duct is arranged along the horizontal direction.

Preferably, the width of each fin is the same, and the width is greater than the maximum outer diameter of the air pipe.

Preferably, the heat dissipation mechanisms are uniformly distributed on the upper surface of the bottom plate in a matrix shape.

Preferably, the outer surfaces of the fins and the air pipe are provided with raised grains.

Preferably, the outer surfaces of the fins and the air pipe are coated with a nano carbon material.

This novel take fin of tuber pipe's beneficial effect does: this is novel through setting up gradually increase gradually fin and one end internal diameter big and the little tuber pipe of other end internal diameter, make to produce the gas flow in the tuber pipe, promote heat dissipation mechanism's radiating efficiency.

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.

A fin radiating fin with an air pipe is shown in figure 1 and comprises a bottom plate 1, wherein a mounting structure for mounting electronic elements is arranged on the lower surface of the bottom plate 1, a plurality of radiating mechanisms are distributed on the upper surface of the bottom plate 1 and comprise a fin group and an air pipe 4, the fin group comprises a plurality of fins 3 which are linearly arranged and sequentially increase in height, and the air pipe 4 is integrally formed at the top end of the fin group;

as shown in fig. 1 and 3, the fins 3 are arranged in parallel;

as shown in fig. 1, the inner diameter of the air duct 4 gradually increases from one end to the other end, and the end with the large inner diameter is located on one side of the fin 3 with the lowest height;

as shown in fig. 2, the top end of each fin 3 is provided with an arc-shaped notch 5 with different inner diameters, and the lower part of the outer wall surface of the air pipe 4 is welded with the arc-shaped notch 5;

as shown in fig. 1, the upper edge of the outer wall surface of the air duct 4 is arranged along the horizontal direction;

as shown in fig. 2 and 3, the width of each fin 3 is the same, and is greater than the maximum outer diameter of the air duct 4;

as shown in fig. 3, the heat dissipation mechanisms are uniformly distributed on the upper surface of the bottom plate in a matrix shape;

the outer surfaces of the fins 3 and the air pipe 4 are provided with raised grains;

the outer surfaces of the fins 3 and the air pipe 4 are coated with nano carbon materials.

This neotype theory of use:

because the fin group comprises a plurality of fins 3 which are arranged along a straight line and are sequentially increased in height, the top end of the fin group is integrally formed with an air pipe 4, further, the inner diameter of the air pipe 4 is gradually increased from one end to the other end, one end with a large inner diameter is positioned on one side of the fin 3 with the lowest height, and the upper edge of the outer wall surface of the air pipe 4 is arranged along the horizontal direction, on one hand, the opening position of one end of the air pipe 4 with the large inner diameter is lower, hot air can easily enter, the opening position of one end of the air pipe 4 with the small inner diameter is higher, and the air temperature is relatively low, so that air flow is generated in; on the other hand, the contact area of the air pipe 4 at one end with large inner diameter and the fins 3 is large, the heat exchange efficiency is high, the air in the air pipe 4 is quickly heated, on the contrary, the contact area of the other end is small, the air in the air pipe is slowly heated, and the temperature difference causes the air in the air pipe 4 to flow, so that the heat exchange is promoted.
