1. Technical Field
The present disclosure relates to a heat sink assembly and, particularly, to a heat sink assembly with a fan.
2. Description of Related Art
Electronic devices in computers, such as central processing units (CPUs), generate a lot of heat during normal operation, which can deteriorate their operational stability, and damage associated electronic devices. Thus, the heat must be removed quickly to ensure normal operation of the CPU. A typical thermal device includes a typical heat sink mounted on a CPU to remove heat. The typical heat sink includes a plurality of parallel fins and several heat pipes passing through the parallel fins. However, the typical thermal device is usually heavy and the efficiency low.
Many aspects of the embodiments can be better understood with references to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
Each fin 20 is perpendicular to the fan 10. The fins 20 are rectangular and have the same height and length. As a whole, the exposed surface of the fins 20 is approximately equal to the area of the face of the fan 10.
A plurality of heat pipes 21 run through the fins 20. A heat pipe is a heat transfer mechanism that can transport large quantities of heat with a very small difference in temperature between the hotter and colder interfaces. Sometimes, inside a heat pipe, at the hot interface a fluid turns to vapor and the gas naturally flows and condenses on the cold interface.
A bracket 30 is mounted on a bottom portion of the heat sink assembly 100 to fix the heat sink assembly 100 in an electronic device. A through hole 22 is defined in each corner of the fins 20 to receive a screw 31. The screws 31 are inserted into the holes 22 to fix the bracket 30 in the electronic device.
Referring to
Each heat pipe 21 quickly transfers heat from the CPU to the fins 20. The fins 20 and the fan 10 dissipate the heat from the CPU. The fins 20 of the heat sink assembly 100 are uniformly distributed. The air flows through the heat sink assembly 100, and flows out from the system fans 90.
It is to be understood, however, that even though numerous characteristics and advantages of the disclosure have been set forth in the foregoing description, together with details of the structure and function of the invention, 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
