Description

Fan structure

This creation is related to a fan structure that is simple in structure and can effectively improve heat dissipation efficiency, and is especially suitable for users of notebook computers.

Various types of integrated circuit components are arranged in various industrial equipments, measuring instruments, and computer equipment. These integrated circuit components must be limited to operate at a predetermined maximum operating temperature to ensure their normal operational functions. . Therefore, these integrated circuit components must be combined with a heat sink to dissipate or discharge the generated thermal energy. Especially for the central processing unit used in the computer system, since it is the operation center of the entire computer system, it is more important to pay attention to the heat treatment.

As the operating speed of the central processing unit or other integrated circuit components becomes faster and faster, the performance requirements of the heat sink are becoming more and more important. The conventional heat sink or heat sink fins are not in need, and it is often necessary to match the fan or the heat pipe. In order to achieve good heat dissipation. In terms of the heat dissipation requirements of notebook computers or lithographic computers, the heat dissipation requirements of the central processing unit are more severe than those of ordinary desktop computers because of their special emphasis on thin, light and short features. However, due to space limitations, the design of the heat sink is greatly limited.

However, at present, in the design of the fan, the motor shaft is mainly driven by a motor, and the fan shaft is designed to protrude from the center of the fan, so that the airflow actually enters the air inlet of the fan and is received by the fan shaft. Blocking the heart, so that the airflow can only be localized around the fan Flowing to the air outlet, the heat dissipation effect of the central processor is not very significant.

The main purpose of this creation is to provide a fan structure that is simple in structure and can effectively improve heat dissipation efficiency.

In order to achieve the above purpose, the present invention provides a fan structure including a body and a vane, the base body is provided with a pair of card portions at a central position, the pair of card portions are provided with a motor, and the seat body is opposite to the pair of cards An opening is formed on each side of the portion, and a vane is formed around the vane, and a card portion is disposed below the central position of the vane for connecting with the motor of the card portion, so that the van can be driven after the motor is started. Turn.

In the implementation, each of the two sides of the card portion is provided with an opening system, which is an air outlet and an air inlet, wherein a heat sink module is coupled to the air inlet.

In implementation, the pair of card portions are an accommodation space formed by the bottom surface of the base body being recessed downward, and the motor is disposed at a central position of the accommodation space, and the card portion below the central position of the blade is When the motor is placed under the vane, the pair of card portions can be engaged with the card portion, so that the wheel can be rotated after the motor is started.

In the implementation, the pair of card portions are formed by the base body protruding upward at a central position, and the card portion below the central position of the blade is recessed inwardly formed on the bottom surface of the wheel below, so that the card is opposite After the portion is engaged with the card portion, the motor can drive the vane to rotate.

In order to further understand the present invention, the preferred embodiments of the present invention, together with the drawings and figure numbers, detail the specific components of the present creation and the effects achieved thereby.

Figure 6 is a schematic cross-sectional view showing the combination of the second embodiment of the present invention.

Please refer to Figures 1~4, which is a first embodiment of the creation fan structure, which is composed of a body 1 and a vane 2.

The base body 1 is recessed downwardly at a central position, and a pair of card portions 11 are disposed. The pair of card portions 11 are provided with a motor 12, and the base body 1 is provided with an opening 13 on each side of the pair of card portions 11, respectively. The air outlet 131 and the air inlet 132 are combined with a heat sink module 14 at the air inlet 132.

A vane 21 is formed around the vane 2, and a central portion of the vane 2 is downwardly provided with a card portion 22, so that after the pair of the card portion 11 is inserted, the motor 12 of the pair of card portions 11 can engage the card portion. 22. When the motor 12 is started, the vane 2 can be rotated.

Therefore, in actual implementation, when the motor 12 is started, the card portion 22 of the vane 2 can be driven by the motor 12 of the portion 11 to rotate the vane 2, so that the airflow enters the seat body from the air inlet 132. After 1 inside, part of the airflow can flow out along the gap between the rotating blade 21 and the seat body 1 in the direction of the air outlet 131, and most of the airflow passes directly over the blade 2 to the air outlet. The direction of 131 flows out.

In addition, referring to FIGS. 5 and 6, which is the second embodiment of the present creation, the difference in the first embodiment is that the pair of card portions 11 are formed by the base body 1 projecting upward at a central position, and The card portion 22 below the central position of the vane 2 is recessed inwardly formed on the bottom surface of the vane 2 so that the motor 12 can drive the vane 2 when the card portion 11 is engaged with the card portion 22 Turn.

Therefore, through the design of the present invention, the airflow entering the seat body 1 is not blocked by the structure of the motor 12 or the blade 21 of the vane 2, so that the air volume of the air outlet 131 can be effectively improved, thereby improving the efficiency of heat dissipation. . Moreover, the present invention is provided with a heat sink module 14 at the air inlet 132. In addition to reducing the temperature of the incoming air stream, when the vane 2 is reversed, the dust is also attached to the heat sink module 14 for dust removal. effect.

The foregoing is a specific embodiment of the present invention and the technical means employed, and many variations and modifications can be derived therefrom based on the disclosure or teachings herein, and can still be regarded as equivalent changes made by the inventive concept. The role of the spirit and the spirit of the text and the scope of the text should be considered within the technical scope of this creation.

In summary, according to the content disclosed above, this creation can achieve the new intended purpose, provide a fan structure, which is highly practical and industrially valuable, and proposes a new type of patent application according to law.
