Description
- 1. Technical Field
- The disclosure generally relates to device cooling, and particularly to a fan module with a plurality of cooling fans.
- 2. Description of Related Art
- Often, a cooling fan is used in a computer to dissipate heat from a Central Processing Unit (CPU) of the computer. On the other hand, the computer system often needs to handle a variety of tasks by changing the CPU for a more powerful one, or expanding via a plurality of Peripheral Component Interconnect (PCI) cards which generate a large amount of heat which need to be dissipated.
- As an amount of the airflow provided by the cooling fan is finite, a single cooling fan is no longer sufficient to timely remove the heat from the more powerful CPU which generates more heat. In addition, an area for the cooling fan airflow passage is also finite, thus the cooling fan can not dissipate heat sufficiently from the CPU and the PCI cards simultaneously. Furthermore, the computer does not form any additional mounting structure for the expansion of cooling capacity via adding another cooling fan to meet a variety of requirements for the computer.
- What is needed, therefore, is a fan module which can overcome the above described limitations.

FIGS. 1 and 2 , afan module 100 according to an exemplary embodiment of the disclosure is shown. Thefan module 100 includes afirst mounting frame 10, afirst cooling fan 20 mounted on thefirst mounting frame 10, asecond mounting frame 30, and asecond cooling fan 40 mounted on thesecond mounting frame 30. Thefirst mounting frame 10 and thesecond mounting frame 30 are located adjacent to one another and in parallel. A right side of thefirst mounting frame 10 is pivotally connected to a left side of thesecond mounting frame 30 by ashaft 50. Theshaft 50 is elongated and rod-shaped. - The
first cooling fan 20 and thesecond cooling fan 40 are the same. Each of thecooling fans fan housing 22 and arotor 24 for generating a forced airflow. Thefan housing 22 is square-shaped and hollow. Therotor 24 is rotatably received in thefan housing 22. A rear side of thefan housing 22 defines anair inlet 27 for the forced airflow to flow into thefan housing 22, and a front side of thefan housing 22 defines anair outlet 28 for the forced airflow to flow out of thefan housing 22. Apassage 220 is defined between the inner surface of thefan housing 22 and therotor 24 for allowing the forced airflow flowing therethrough. Thefan housing 22 defines fourmounting holes 222 at four corners surrounding theair inlet 27 respectively, and defines fourmounting holes 222 at four corners surrounding theair outlet 28, respectively. - Referring to
FIG. 3 , thefirst mounting frame 10 includes a squaremain body 12, alatching flange 14 extending frontward from a left side of themain body 12, two spacedfixing tabs 16 extending rearward from a right side of themain body 12, and a connectingportion 18 extending outwardly from the right side of themain body 12 and located between thefixing tabs 16. In this embodiment, both of thelatching flange 14 and thefixing tabs 16 perpendicularly intersect themain body 12, respectively. - The
main body 12 of thefirst mounting frame 10 is in the form of a flat plate. Themain body 12 defines a throughhole 120 at a central area thereof corresponding to theair outlet 28 of thefirst cooling fan 20. The throughhole 120 has a diameter substantially equal to that of theair outlet 28 of thefirst cooling fan 20. Themain body 12 defines fourfixing holes 122 corresponding to themounting holes 222 of thefirst cooling fan 20, respectively. - The
fixing tabs 16 are respectively located adjacent to the top and bottom ends of themain body 12. Each of thefixing tabs 16 is substantially square. Eachfixing tab 16 forms afirst hook 162 at a distal end thereof. - The
latching flange 14 is rectangular and elongated. Thelatching flange 14 extends along the left side of themain body 12. Two spacedsecond hooks 142 are formed on thelatching flange 14. Thesecond hooks 142 are respectively located adjacent to the top and bottom ends of thelatching flange 14. - The connecting
portion 18 is elongated and column-shaped. The connectingportion 18 extends along the right edge of themain body 12. The connectingportion 18 defines anaxial hole 180 therethrough along a lengthwise direction thereof for allowing theshaft 50 to extend through. A cross section of the connectingportion 18 is substantially C-shaped in this embodiment. - Referring to
FIG. 4 , thesecond mounting frame 30 includes a squaremain body 32, afixing flange 34 extending rearward from a right side of themain body 32, two spacedlatching plates 36 extending rearward from a left side of themain body 32, and two spacedfixing portions 38 extending outwardly from the left side of themain body 32. - The
main body 32 of thesecond mounting frame 30 is also in the form of a square flat plate. Themain body 32 defines anopening 320 at a central area corresponding to theair outlet 28 of thesecond cooling fan 40. Four corners of themain body 32 each define afixing hole 322 corresponding to themounting holes 222. - Each of the
latching plates 36 is substantially square-shaped. Thelatching plates 36 each define afirst latching hole 360 corresponding to thefirst hook 162 of onefixing tab 16 of thefirst mounting frame 10. - The
fixing flange 34 is rectangular and elongated. Thefixing flange 34 extends along the right side of themain body 32. Thefixing flange 34 defines two spacedsecond latching holes 340 corresponding to thesecond hooks 142 of thelatching flange 14 of thefirst mounting frame 10, respectively. Each of thesecond latching holes 340 is rectangular. In this embodiment, thefixing flange 34 is perpendicular to themain body 32. - The
fixing portions 38 are spaced from each other. A distance between thefixing portions 38 is slightly larger than a length of the connectingportion 18. Each of thefixing portions 38 defines apivotal hole 380 therethrough. Thepivotal holes 380 of thefixing portions 38 are aligned for allowing theshaft 50 to extend through. In this embodiment, a cross section of eachfixing portion 38 is substantially C-shaped. - In assembly, the
first mounting frame 10 and thesecond mounting frame 30 are arranged adjacent to one another and in parallel. The first hooks 162 of the first mountingframe 10 hook or engage in the first latching holes 360 of the latchingplates 36, respectively. At the same time, the connectingportion 18 of the first mountingframe 10 is located between the fixingportions 38 of the second mountingframe 30, with theaxial hole 180 of the connectingportion 18 aligned with thepivotal holes 380 of the fixingportions 38. Theshaft 50 extends through thepivotal hole 380 of oneupper fixing portion 38, theaxial hole 180 of the connectingportion 18, and thepivotal hole 380 of the other fixingportion 38 sequentially, to thereby pivotally connect the first mountingframe 10 and the second mountingframe 30. Therefore, the first mountingframe 10 is rotatable relative to the second mountingframe 30. - The
first cooling fan 20 is arranged at a rear side of the first mountingframe 10, with theair outlet 28 of thefirst cooling fan 20 aligned with the throughhole 120 of the first mountingframe 10. Four mountingholes 222 of thefirst cooling fan 20 are respectively aligned with the four fixingholes 122 of the first mountingframe 10. Then, fourfasteners 60, such as screws, are provided to extend through the fixingholes 122 of the first mountingframe 10 and engage with the mountingholes 222 of thefirst cooling fan 20, thereby fixing thefirst cooling fan 20 on the first mountingframe 10. Thesecond cooling fan 40 is fixed on the second mountingframe 30 by the same method as thefirst cooling fan 20. - As the first mounting
frame 10 is connected with the second mountingframe 30, thefirst cooling fan 20 mounted on the first mountingframe 10 and thesecond cooling fan 40 mounted on the second mountingframe 30 are thus connected together. That is, the number of the coolingfans fan module 100 is expanded by the first mountingframe 10 and the second mountingframe 30. - In addition, in such a state, the
first cooling fan 20 and thesecond cooling fan 40 are located adjacent to one another and in parallel, and the orientations of theair outlets 28 of thefirst cooling fan 20 and thesecond cooling fan 40 are adjacent to one another and parallel. Therefore, an airflow area produced by thefirst cooling fan 20 and thesecond cooling fan 40 is larger than that of the airflow area produced by one coolingfan fan module 100 can efficiently and timely remove heat from the CPU and the PCI cards simultaneously. - Referring to
FIG. 5 , as the first mountingframe 10 is pivotally connected with the second mountingframe 30, the first mountingframe 10 can be rotated relative to the second mountingframe 30, and thus a location relationship between thefirst cooling fan 20 and thesecond cooling fan 40 can be changed to meet different requirements of heat dissipation of the computer. For example, if the heat generated by the CPU is too large that the airflow produced by one coolingfan frame 10 can be rotated relative to the second mountingframe 30 to make thefirst cooling fan 20 and thesecond cooling fan 40 arranged in series, thereby enhancing airflow speed, and thus removing heat of the CPU more quickly. - When the first mounting
frame 10 is rotated relative to the second mountingframe 30, the left side of the first mountingframe 10 moves towards the right side of the second mountingframe 30. The first hooks 162 of the first mountingframe 10 then depart from the first latching holes 360 of the second mountingframe 30. After the first mountingframe 10 is rotated by slightly less than 180°, themain body 12 of the first mountingframe 10 faces themain body 32 of the second mountingframe 30. The second hooks 142 of the latchingflange 14 of the first mountingframe 10 touch the fixingflange 34 of the second mountingframe 30. - Then the first mounting
frame 10 is further pushed towards the second mountingframe 30, to make thesecond hooks 142 hook or engage in the second latching holes 340 of the fixingflanges 34 of the second mountingframe 30. In such an operating state, the first mountingframe 10 overlaps the second mountingframe 30. Thefirst cooling fan 20 and thesecond cooling fan 40 are arranged in series.Air outlets 28 of thefirst cooling fan 20 and thesecond cooling fan 40 are aligned. - It is worthwhile to note that, when the
first cooling fan 20 and thesecond cooling fan 40 are arranged in parallel, the directions of the airflow of thefirst cooling fan 20 and thesecond cooling fan 40 are the same. After the coolingfan 20 has been directly rotated to be arranged in series with thesecond cooling fan 40, the air outlets of thefirst cooling fan 20 and thesecond cooling fan 40 face each other, and the orientations of theair outlets 28 of thefirst cooling fan 20 and thesecond cooling fan 40 are opposite to each other. - Thus, the
first cooling fan 20 should be disassembled from the first mountingframe 10 and be reversely remounted on the first mountingframe 10 before the first mountingframe 10 has been rotated towards the second mountingframe 30, with theair inlet 27 of thefirst cooling fan 20 located closer to themain body 12 of the first mountingframe 10 than theair outlet 28 of thefirst cooling fan 20. Therefore, after the first mountingframe 10 has been rotated to overlap the second mountingframe 30 to make thefirst cooling fan 20 and thesecond cooling fan 40 arranged in series, theair inlet 27 of thefirst cooling fan 20 faces theair outlet 28 of thesecond cooling fan 40. Thus, airflow of thefirst cooling fan 20 and thesecond cooling fan 40 flows along a same direction, and the airflow speed flowing to the CPU is increased, accordingly. - It is to be understood, however, that even though numerous characteristics and advantages of certain embodiment(s) have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
