Abstract
Description
- 1. Technical Field
- The present disclosure relates to a heat dissipation apparatus.
- 2. Description of Related Art
- With developments in computing technology, electronic devices such as central processing units (CPUs) generate excessive heat during normal operation, which can deteriorate operational stability and damage associated elements. The heat must be removed quickly. A commonly used heat dissipation apparatus includes a heat sink mounted on a CPU. The typical heat sink includes a plurality of parallel fins and several heat pipes passing therethrough. However, such apparatus is heavy and dissipating 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.
-
FIG. 1 is an exploded view of an embodiment of a heat dissipation apparatus. -
FIG. 2 is an assembled view of the heat dissipation apparatus ofFIG. 1 . -
FIG. 1 is an exploded view of an embodiment of a heat dissipation apparatus. The heat dissipation apparatus includes aheat sink 10, and afan 20 configured to be fixed on theheat sink 10. - The
heat sink 10 includes abase 11, and a plurality ofradial fins 12 formed on a top surface of thebase 11. A bottom surface of thebase 11 is configured to contact a heat source, such as a central processing unit (CPU). The heat generated by the heat source is transmitted to thefins 12 via thebase 11. Thefins 12 angle upwardly from the top surface of thebase 11 to form a truncated conical space in the middle of theheat sink 10. A cross section of the truncated conical space gradually increases from the top surface of thebase 11 to a top end of thefins 12. A top of the truncated conical space forms an air inlet for thefan 20. A plurality of guidingmembers 13 is formed behind theoutmost fins 12 to define a plurality ofair outlets 14 betweenadjacent fins 12. The airflow from the air inlet passes through thefins 12, and out theair outlets 14. - Referring to
FIG. 2 , thefan 20 is mounted on theheat sink 10 aligned with the air inlet of theheat sink 10. Thefan 20 is mounted to theheat sink 10. - When the
fan 20 rotates, airflow generated passes through thefins 12. As a result of the shape of the truncated conical space in the middle of theheat sink 10, speed of the airflow is accelerated when passing therethrough, reaching a maximum value at the top surface of thebase 11. The high speed airflow strongly affects the top surface of thebase 11, and heat accumulated therearound is dissipated swiftly. Here, thefins 12 and guidingmembers 13 are integrally formed with thebase 11, and the weight of theheat sink 10 is minimized. - 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
