Abstract

(57) [Problem] To provide a cooling device for a central processing unit provided with an in-line double fan and a thin and small heat radiation fin. SOLUTION: Two or more fans are connected in series, and a second fan 3 which exhausts inward is driven by the impact force of exhaust of a first fan 2, thereby simultaneously rotating two coaxial fans. . In addition, a large series of winds can be absorbed by increasing the pressure of the gas with a double-series fan, so that the air can be eliminated immediately to achieve the effect of cooling. Thereby, the large area of the heat radiation fin 1 can be reduced, and the installation space can be largely saved. With the structure of a double-series fan, if one of the fans breaks, another fan can be used instead. If one of the fans fails and cannot provide the cooling effect, the other fan can be used continuously to avoid problems caused by the conventional failure of the fan and not repairing it. It is.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cooling device for a central processing unit.

[0002]

[Prior art]

 Conventionally, a cooling device installed in a central processing unit uses a heat dissipating fin corresponding to the size of the central processing unit. The fins that have absorbed the heat are cooled by the fan connected to the fins when the fins are cooled by firmly abutting them with the chip of the central processing unit and fixing them together with a fixing device. Because the temperature is cooled and the temperature is reduced, the central processing unit can be provided without prolonged damage due to overheating even when used for a long time.

[0003]

[Problems to be solved by the invention]

 Conventionally, due to the cooling structure, there is one large-volume radiating fin and one fan. There is only one fan installed for cooling. Therefore, if the fan is broken and not found, the central processing unit may overheat and cause damage such as inability to operate the main unit. In addition, since the size of the chip of the central processing unit is smaller than the substrate of the entire central processing unit, installing a large-sized heat radiation fin wastes cost and space. The main object of the present invention is to provide a cooling device for a central processing unit having a series double fan and a thin and small heat radiation fin. Another object of the present invention is to provide a series double fan which provides a kind of spare and alternative function.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the cooling device for a central processing unit according to the claims of the present invention has at least two or more fans connected in series, and several fans are connected between the fans. The columns have a distance between them. By driving the second fan that exhausts inward by the impact force of the exhaust of the first fan, the two coaxial fans are simultaneously rotated, pressurizing the air, and eliminating a large amount of wind, and The effect of cooling immediately can be achieved. When the radiating fin absorbs the high temperature of the central processing unit, a large amount of wind can be absorbed by increasing the pressure with a series double fan, and the cooling effect and speed can be increased. By reducing the volume of the heat dissipating fins, adding a structure combining a series of double fans does not increase the thickness of the central processing unit. Because the fan has the function of eliminating a large amount of wind, the area where the heat radiation fins are installed can be reduced sufficiently.

[0005] In the structure of a series double fan, if one of the fans breaks, another fan can be used immediately instead. If one of the fans fails and cannot provide the cooling effect, the other fan can continue to be used, thereby avoiding the problems caused by the conventional failure of the fan and the failure to repair it. It is.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the cooling device according to one embodiment of the present invention has one heat dissipating fin 1 and at least two or more fans (in the figures, two fans are described).

The heat radiation fin 1 is designed to be thin and small in volume. Blades 22 and 32 are provided outside the bases 21 and 31 of the first fan 2 and the second fan 3. At four corners of the base 21 and the base 31, a through hole 211 and a through hole 311 are provided.

Since the connecting column 312 is provided outside the through holes 311 on the base 31, when the first fan 2 is installed in a coaxial series system with the second fan 3, the first fan 2 is screwed with the screw 23. After penetrating from the outer through-hole 211 to the through-hole 311 of the second fan 3, the two fans are connected to each other. I have.

As shown in FIG. 3, a second fan having a structure in which a first fan 2 provided on the outside exhausts inward due to the structure of a series-type double fan, and the inside of which faces the heat dissipating fin 1 tightly. Since the displacement and the pumping speed of the fin 3 can be increased, the cooling fin 1 can achieve the purpose of cooling in the shortest time. Regarding the connection of the two fans, a space is formed in the connection column 312 between the first fan 2 and the second fan 3 described above, and the distance is formed, so that the second fan 3 allows the outside air to be removed from the surroundings. If one of the fans breaks and cannot provide the function of removing the wind because it can be sucked in, another fan can be used subsequently as an alternative function. In particular, the second fan 3 on the inside can be used. If it breaks, if it does not form a distance with the first fan 2 on the outside, the effect of inhaling the outside air and providing the heat-dissipating fins 1 with the function of exhausting and lowering the temperature will be impaired. Another fan can be operated independently from the time one fan breaks down to the time it is repaired. A.
