BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to a fan motor assembly, and more particularly relates to a fan motor assembly including two or more fans arranged adjacent to each other. [0003] 2. Description of the Related Art [0004] Recently, high-end electrical circuits are installed in electrical devices, and such electrical devices generate considerable heat. The electrical devices are generally equipped with a plurality of fans to actively dissipate the heat. [0005] Also recently, it is preferable that the electrical devices have reduced dimensions, such that the electrical devices are likely to be designed to minimize their dimensions. As a result, the space to house a fan motor assembly is limited as well. [0006] The fan includes a lead wire for supplying electricity thereto. When a plurality of fans are provided in the casing of the electrical device, a lead wire of the fan arranged farther from the power source is wired at the outer periphery of the fan arranged nearer the power source. However, in view of the efficient layout of other components within the electrical device casing, the size of a fan housing has to be reduced in order to secure the space for the lead wire. Generally, upon reducing the size of a housing dimension of the fan, a dimension of the wind channel is reduced as well. Consequently, a size of an impeller of the fan is reduced, which results in degrading the airflow and cooling characteristics of the fan. SUMMARY OF THE INVENTION [0007] In order to overcome the problems described above, preferred embodiments of the present invention provide a fan motor assembly including a primary fan and at least one additional fan. A lead wire connecting the at least one additional fan and an external power source is wired on a surface of an air inlet side or an air outlet side of the primary fan, and then, is led out of the primary fan. [0008] According to another preferred embodiment of the present invention, each fan includes a flange portion at a position outside of a passage of air flow and is either on an air outlet side or an air inlet side of the fan. [0009] According to another preferred embodiment of the present invention, a lead wire connecting the primary fan and the external power source is led out of the primary fan while being bundled together with the lead wire of the additional fan. [0010] By virtue of the unique configuration described above, it is not necessary to secure a space for wiring the lead wire around the fan motor assembly. Therefore, it is not necessary to reduce the inner dimension of the housing or the outer dimension of the impeller. As a result, the fan motor assembly may be installed in a limited space while maintaining appropriate airflow and cooling characteristics. [0011] In the description of the preferred embodiments of the present invention, words such as upper, lower, left, right, upward, downward, top, and bottom for explaining positional relationships between respective members and directions merely indicate positional relationships and directions in the drawings. Such words do not indicate positional relationships and directions of the members mounted in an actual device. [0012] Other features, elements, processes, steps, characteristics and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the present invention with reference to the attached drawings.
