In this embodiment, a length of the second air outlet opening 312 is substantially equal to a length of the plurality ofair outlet slots 23. - The
portable device 40 includes amain body 41 and acover plate 42. Thecover plate 42 is mounted on themain body 41. A plurality of thirdair inlet openings 43 is defined in one side of themain body 41. A plurality of thirdair outlet openings 44 is defined in a top of themain body 41.

In this embodiment, the firstheat dissipation element 411 is a CPU, and the secondheat dissipation element 412 is a power control unit. -
FIGS. 1 to 3 show that in assembly, thefan 30 is fixed in theduct body 21 of theair duct 20, such that the second air outlet opening 312 of thefan 30 is aligned with the plurality ofair outlet slots 23 of theduct body 21. Theduct body 21 is received in the firstinserting slot 13, such that the first air inlet opening 22 of theair duct 20 communicates with an inside of the firstinserting slot 13. Theheat sink 413 is mounted on the firstheat dissipation element 411 and the secondheat dissipation element 412.

Theportable device 40 is received in the secondinserting slot 14. Thecover plate 42 of theportable device 40 abuts against theduct body 21. The plurality ofair outlet slots 23 face thecover plate 42. -
FIG. 4 shows that in operation, the firstheat dissipation element 411 and the secondheat dissipation element 412 generate large amounts of heat when theportable device 40 is powered on. The heat generated by the firstheat dissipation element 411 and the secondheat dissipation element 412 is transmitted to theheat sink 413. A first amount of air from outside theexpansion base 10 enters theportable device 40 via the plurality of thirdair inlet openings 43 or the plurality of thirdair outlet openings 44. The first amount of air displaces some heat accumulated in theheat sink 413. The heated first amount of air then exits from theportable device 40 through the plurality of thirdair outlet openings 44 or the plurality of thirdair inlet openings 43. A second amount of air from outside theexpansion base 10 is sucked into thefan 30 via the plurality ofair inlet slots 12 and the second air inlet opening 311. A speed of the second amount of air is increased when passing through thefan 30. The second amount of air is blown out of thefan 30 through the second air outlet opening 312 toward the plurality ofair outlet slots 23 of theair duct 20. The second amount of air is diagonally blown out of theair duct 20 through the plurality ofair outlet slots 23. The second amount of air is blown toward thecover plate 42 of theportable device 40 to remove heat accumulated on thecover plate 42. Therefore, a temperature of theportable device 40 is further decreased. - In this embodiment, the
duct body 21 of theair duct 20 is made of heat-conducting material. The heat accumulated on thecover plate 42 of theportable device 40 is partially transmitted to theduct body 21. The second amount of air passes through theduct body 21 and removes the heat accumulated on theduct body 21. Therefore, the three described modes of heat dissipation significantly improve a heat dissipation efficiency of the heat dissipation apparatus. - Using a software application called ICEPAK to simulate the efficiency of the heat dissipation apparatus, the following results of an embodiment shown below were obtained. The simulated conditions were set as follows: a power dissipation of the first
heat dissipation element 411 is 2 watts (W). A power dissipation of a memory of theportable device 40 is 1.5 W. A power dissipation of the secondheat dissipation element 412 is 0.6 W. Thefan 30 has a dimension of 92 millimeters (mm)×92 mm×25 mm (length×width×height). A maximum air flow rate of thefan 30 is 35.32 cubic feet per minute (cfm). A rated speed of thefan 30 is 2000 revolutions per minute (rpm). A maximum static pressure of thefan 30 is 0.084 inch-H2O. - The simulation according to the set conditions shows that when using the heat dissipation apparatus of the disclosure, a maximum temperature of the
cover plate 42 of theportable device 40 is 45 degrees Celsius, a maximum temperature of the firstheat dissipation element 411 is 46 degrees Celsius, a maximum temperature of the memory is 45.3 degrees Celsius, and a maximum temperature of the secondheat dissipation element 412 is 48.2 degrees Celsius. In contrast, when using another heat dissipation apparatus, the back of theportable device 40 has a maximum temperature of 45.9 degrees Celsius, the firstheat dissipation element 411 has a maximum temperature of 100.4 degrees Celsius, the memory has a maximum temperature of 100.7 degrees Celsius, and the secondheat dissipation element 412 has a maximum temperature of 101.7 degrees Celsius. As can be seen, when using the heat dissipation apparatus of the disclosure, the maximum temperature of theportable device 40 is largely decreased, and heat dissipation efficiency is improved. - Even though numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and the arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
