FIELD OF THE INVENTION [0001] The present invention relates to fan assemblies, more particularly to a fan assembly consisting of a plurality of fans. The fan assembly is characterized by a plurality of support units, by which the vibrations caused by driving units on the fan wheel hubs and the fan brackets will be reduced. BACKGROUND OF THE INVENTION [0002] Referring to FIGS. 1 and 2, a fan assembly 1 of the prior art comprises a plurality of fans 11 each having a fan bracket 111, a fan wheel hub 112a installed within the fan bracket 111, a set of fan blades 112b mounted around the fan wheel hub 112a and a driving unit 113 installed in the fan wheel hub 112a for rotating the fan blades 112b; the driving unit 113 can be an electric motor. A plurality of through holes 111c is formed around the front face 111a, going through the fan bracket 111 to the rear face 111b thereof, for the attachment of the fan assembly 1 to another device. The driving unit 113 drives the fan blades 112b to produce airflow for cooling the device the fan assembly 1 attached to. [0003] Referring to FIG. 3, the fan assembly 1 is installed on a device 2 to be cooled. The device 2 is provided with a plurality of retaining plates 21, each having screw holes 211 corresponding to the through holes 111c of the fan assemblies 1, whereby a plurality of screw units 211a will be respectively inserted through the screw holes 211 on the retaining plates 21, the corresponding through holes 111c on the fan assemblies 1 for securing the fan assemblies 1 on the device 2. [0004] The fan assembly 1 of the prior art has the disadvantages as follows. [0005] (1) When the driving units are running, there will be vibrations produced on the fan brackets, resulting in a mutual influence between the fans. [0006] (2) The vibrations of the fan brackets cause noises. SUMMARY OF THE INVENTION [0007] Accordingly, the primary objective of the present invention is to provide a fan assembly wherein a plurality of fans can be connected by direct contact of their fan brackets. [0008] The secondary objective of the present invention is to provide a fan assembly wherein the vibrations caused by driving units on the fan wheel hubs and the fan brackets will be reduced. [0009] It is a further objective of the present invention that the fans are in a tight and flexible contact when mounted on a device. [0010] It is a further objective of the present invention that the combined structure of the fans is reinforced by the way they are connected and by the support units disposed between the fans. [0011] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings. BRIEF DESCRIPTION OF THE DRAWINGS [0012] FIG. 1 is an exploded perspective view of a fan assembly of the prior art. [0013] FIG. 2 is a perspective view of the fan assembly in FIG. 1. [0014] FIG. 3 is a perspective view of the fan assembly in FIG. 1 installed within an external device. [0015] FIG. 4 is an exploded perspective view of the first preferred embodiment of the present invention as a fan assembly. [0016] FIG. 5 is a perspective view of the fan assembly in FIG. 4. [0017] FIG. 6 is a perspective view of the fan assembly in FIG. 4 installed within an external device. [0018] FIG. 7 is an exploded perspective view of the second preferred embodiment of the present invention as a fan assembly. [0019] FIG. 8 is a perspective view of the fan assembly in FIG. 7. [0020] FIG. 9 is a front view of the fan assembly in FIG. 7. Continue reading about Fan assembly...
