Abstract
Description
- 1. Technical Field
- The present disclosure relates to blower assemblies and, particularly, to a blower assembly for dissipating heat from an electronic device.
- 2. Description of Related Art
- Electronic devices, such as central processing units (CPUs) and printed circuit boards (PCBs), frequently generate large amount of heat during normal operation, which can destabilize operation of the electronic devices and possibly cause damage. Oftentimes, a heat dissipation assembly is used to dissipate heat from an electronic device. The heat dissipation assembly usually comprises a fan.
- As computer technology continues to advance, the electronic devices of computers are being made to provide faster operational speeds and greater functional capabilities, which in turn cause more heat to be generated. Therefore, blowers are used to dissipate the generated heat instead of ordinary fans. However, including a general blower for a PCB will often give rise to limitations in manufacturing the PCB.
- What is needed, therefore, is to provide a blower assembly to overcome the above described shortcomings.
-
FIG. 1 is an exploded, isometric view of an exemplary embodiment of a blower assembly, together with a printed circuit board and a chip. -
FIG. 2 is an assembled view ofFIG. 1 . - Referring to
FIG. 1 , an exemplary embodiment of ablower assembly 20 is provided for dissipating heat generated by a printed circuit board (PCB) 12, such as a memory card, or a graphics card. ThePCB 12 includes agold finger 16 configured for engaging in a PCB slot, such as a peripheral component interconnect (PCI) slot, and achip 14 set on thePCB 12 which is a main heat source. - The
blower assembly 20 includes abracket 29 and afan 22 rotatably installed in thebracket 29. Thebracket 29 is generally shaped like a flat rectangular box. Asidewall 26 of thebracket 29, which is perpendicular to an axis of thefan 22, defines around inlet 24 for exposing thefan 22. Alateral wall 27 of thebracket 29, which is parallel to the axis, defines a fixingslot 232, and anoutlet 236 communicated with the fixingslot 232. The fixingslot 232 is configured for receiving one end of thePCB 12, such as an end adjacent thegold finger 16, with theoutlet 236 aligning with thechip 14. Air can be expelled out of theblower assembly 20 through theoutlet 236 to cool thechip 14. Two corners of thesidewall 26 adjacent theoutlet 236 define two mounting parts, such as two mountingholes PCB 12 in the fixingslot 232 viascrews 30. - In other embodiments, the
bracket 29 is not limited to the shape as shown inFIG. 1 , the number of the mounting holes is not limited to two, the mountingholes sidewall 26, and theinlet 24 and theoutlet 236 can be defined in other positions as needed. Because the size of theinlet 24 determines the volume of air intake, the size of theinlet 24 can be also be changed as needed. - Referring to
FIG. 2 , in assembly, the end of thePCB 12 is engaged in the fixingslot 232 of theblower assembly 20. Thescrews 30 extend through the mountingholes PCB 12, thereby securing theblower assembly 20 to the end of thePCB 12. - In operation, when the
fan 22 of theblower assembly 20 rotates, air is sucked into theblower assembly 20 through theinlet 24. After being pressurized by thefan 22, the air is expelled out of theblower assembly 20 through theoutlet 236 toward thechip 14. Thereby, thechip 14 is cooled. - It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function 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 embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
