- Reference is first made to
FIGS. 1 to 9 , which show an embodiment of the instant disclosure. As shown inFIGS. 1 and 2 , the instant embodiment discloses aheat dissipating device 100 that includes acarrier 1, amagnetic driving module 2, twoswing structures 3, and a plurality offixing rivets 4. Themagnetic driving module 2 is installed to thecarrier 1. The twoswing structures 3 are fastened to thecarrier 1 by using thefixing rivets 4 and correspond in position to themagnetic driving module 2. The number of thefixing rivets 4 in the instant embodiment is four, but is not limited thereto. For example, the number of thefixing rivets 4 may be two for respectively fixing the twoswing structures 3 onto thecarrier 1. - As shown in
FIGS. 3 through 7 , thecarrier 1 is suitable to be formed by insert molding. Thecarrier 1 includes twobases 11 and a tube-like connecting portion 12 (as shown inFIG. 5 ) connecting the twobases 11. The twobases 11 in the instant embodiment are in a mirror symmetrical arrangement with respect to the connectingportion 12. As the twobases 11 in the instant embodiment are of the same structure, the following description discloses the structure of just one of the twobases 11 for the sake of brevity. Thebase 11 includes aninner surface 111, anouter surface 112 opposing to theinner surface 111, and twoopposite end surfaces 113. Theinner surface 111 is connected to the connectingportion 12. Thebase 11 has apositioning trough 114 formed on theouter surface 112. The twoend surfaces 113 are of the same shape. At least onefixing hole 115 is recessed in at least one of the twoend surfaces 113, such that thecarrier 1 can be fixed onto an external object (not shown) by extending a screw (not shown) through thefixing hole 115 and into the external object. Moreover, thefixing hole 115 can be a blind hole or a thru-hole. - In other words, two opposite ends of the connecting
portion 12 are respectively connected to theinner surfaces 111 of the twobases 11. Thepositioning troughs 114 of the twobases 11 are respectively formed on the twoouter surfaces 112 of thecarrier 1. Specifically, in each of the twobases 11, thepositioning trough 114 includes abottom flange 1141 formed on a bottom edge of theouter surface 112, and twoside flanges 1142 respectively formed on two opposite side edges of theouter surface 112. Thebottom flange 1141 and the twoside flanges 1142 of each of the twobases 11 are in a U-shape. - However, the structure of the
positioning trough 114 is not limited to the above description. For example, as shown inFIG. 10 , in each of the twobases 11, thepositioning trough 114 includes abottom flange 1141 formed on a bottom edge of theouter surface 112, and aside flange 1142 formed on a side edge of theouter surface 112. Thebottom flange 1141 and theside flange 1142 of each of the twobases 11 are in an L-shape. - The
magnetic driving module 2 is configured to generate a magnetic field (not shown). The magnetic field defines two magnetic areas (i.e., a left area and a right area of themagnetic driving module 2 as shown inFIG. 4 ) respectively having two opposite magnetisms. Themagnetic driving module 2 is configured to cyclically change the magnetisms of the two magnetic areas by receiving a periodic power (not shown). The periodic power can be periodic square waves, periodic triangle waves, periodic sine waves, or the positive and negative half-cycle period of alternating currents. The periodic power exemplified in the instant embodiment is the positive and negative half-cycle period of alternating currents. - Specifically, the
magnetic driving module 2 in the instant embodiment includes an elongated core 21 (i.e., iron core) and acoil 22. Thecore 21 couples into the connectingportion 12 of thecarrier 1 in a tight-fitting connection, and thecoil 22 is wound around an outer side of the connectingportion 12 of thecarrier 1. Thecoil 22 is electrically connected to the periodic power. When the periodic power emits a current to travel in thecoil 22, thecoil 22 and the core 21 generate the magnetic field, and the magnetisms of the two magnetic areas are cyclically changed with time. - As the two
swing structures 3 in the instant embodiment are of the same structure, the following description discloses just one of the twoswing structures 3 for the sake of brevity. Theswing structure 3 includes anelongated blade 31, apositioning rivet 32, and amagnetic actuation 33 fixed on theblade 31 by using thepositioning rivet 32. Theblade 31 has a rectangular shape and may be a glass-fiber blade or a polyester blade. Theblade 31 includes a mountingportion 311 and afree end portion 312 respectively arranged on two opposite portions thereof. Themagnetic actuation 33 is fixed on a portion of theblade 31 arranged between the mountingportion 311 and thefree end portion 312. Specifically, themagnetic actuation 33 in the instant embodiment has twomagnets 331 respectively disposed on two opposite surfaces of theblade 31, but themagnetic actuation 33 in another embodiment (not shown) of the instant disclosure can be asingle magnet 331. Thepositioning rivet 32 is made of plastic or metal and includes ashaft portion 321 and two abuttingportions 322. The two abuttingportions 322 are respectively and integrally connected to two opposite ends of theshaft portion 321. An outside diameter of each of the abuttingportions 322 is larger than that of theshaft portions 321. Theshaft portion 321 is inserted into theblade 31 and the twomagnets 331, and the two abuttingportions 322 are respectively abutted against outer surfaces of the twomagnets 331. Moreover, theshaft portion 321 and the two abuttingportions 322 of thepositioning rivet 32 in the instant embodiment each has a hollow structure, but theshaft portion 321 and the two abuttingportions 322 of thepositioning rivet 32 in the other embodiment (not shown) each can be of a solid structure. - The mounting
portions 311 of the twoblades 31 are respectively positioned in the twopositioning troughs 114, and a bottom edge of each of the twoblades 31 is abutted against thebottom flange 1141 of thecorresponding positioning trough 114. Accordingly, theblade 31 does not protrude from a bottom surface of thecorresponding base 11, so as to simplify the assembling process of theheat dissipating device 100. Moreover, the fixingrivets 4 are used to respectively fasten the mountingportions 311 of the twoblades 31 onto twoouter surfaces 112 of thecarrier 1, such that the twoblades 31 are in a parallel arrangement and the twomagnetic actuations 33 are respectively arranged in the two magnetic areas. - Specifically, each of the fixing rivets 4 is made of plastic or metal and includes a
shaft portion 41 and two abuttingportions 42. In each of the fixing rivets 4, the two abuttingportions 42 are respectively and integrally connected to two opposite ends of theshaft portion 41. An outside diameter of each of the abuttingportions 42 is larger than that of theshaft portions 41. In the instant embodiment, theshaft portion 41 and the two abuttingportions 42 of each of the fixing rivets 4 each has a hollow structure, but theshaft portion 41 and the two abuttingportions 42 of each of the fixing rivets 4 in another embodiment (not shown) of the instant disclosure each can be of a solid structure. - Moreover, the
shaft portions 41 of the two fixingrivets 4 are respectively inserted into the mountingportions 311 of the twoblades 31 and are respectively inserted into the twobases 11, and the two abuttingportions 42 of each of the fixing rivets 4 are respectively abutted against the mountingportion 311 of thecorresponding blade 31 and theinner surface 111 of thecorresponding base 11. One of the two abuttingportions 42 of each of the two fixingrivets 4 abutted against the mountingportion 311 of thecorresponding blade 21 is arranged in thepositioning trough 114 of thecorresponding base 11. Accordingly, each of the abuttingportions 42 does not protrude from thepositioning trough 114 of thecorresponding base 11, so as to simplify the assembling process of theheat dissipating device 100. - When the
magnetic driving module 2 generates the magnetic field, the twomagnetic actuations 33 are moved by the two magnetic areas to swing thefree end portions 312 of the twoblades 31. The twoblades 31 of theheat dissipating device 100 can swing in the same direction (as shown inFIG. 8 ) or in an opposite direction (as shown inFIG. 9 ). - In addition, the
swing structure 3 of the instant disclosure can be changed according to practical needs and is not limited to that shown in the figures. For example, in each of the twoswing structures 3 as shown inFIGS. 10 through 13 , themagnetic actuation 33 includes at least onemagnet 331 and at least onebuffering pad 332 abutted against theblade 31. The at least onemagnet 331 and the at least onebuffering pad 332 are fixed on theblade 31 by thepositioning rivet 32. - Specifically, as shown in
FIG. 10 , themagnetic actuation 33 includes amagnet 331 and abuffering pad 332 sandwiched between themagnet 331 and theblade 31. Themagnet 331 and thebuffering pad 332 are fastened to theblade 31 by thepositioning rivet 32. - As shown in
FIG. 11 , themagnetic actuation 33 includes twomagnets 331 and twobuffering pads 332 respectively disposed on two opposite surfaces of theblade 31. The twomagnets 331 are respectively disposed on the twobuffering pads 332, and themagnets 331 and thebuffering pads 332 are fastened to theblade 31 by thepositioning rivet 32. - As shown in
FIG. 12 , themagnetic actuation 33 includes amagnet 331 and abuffering pad 332 both respectively disposed on two opposite surfaces of theblade 31. Themagnet 331 and thebuffering pad 332 are fastened to theblade 31 by thepositioning rivet 32. - As shown in
FIG. 13 , themagnetic actuation 33 includes twomagnets 331 respectively disposed on two opposite surfaces of theblade 31 and twobuffering pads 332 respectively disposed on themagnets 331. Themagnets 331 and thebuffering pads 332 are fastened to theblade 31 by thepositioning rivet 32. - In summary, the heat dissipating device of the instant disclosure adapts the positioning rivets to fix the magnetic actuations onto the blades and adapts the fixing rivets to fix the blades onto the carrier, so that the structure of the heat dissipating device can be easily mass produced with automated equipment.
- Moreover, the mounting portions of the two blades are respectively positioned in the two positioning troughs, and one of the abutting portions of each of the fixing rivets abutted against the mounting portion of the corresponding blade is arranged in the positioning trough of the corresponding base, so that the blades do not protrude from the bottom surface of the bases and each of the abutting portions does not protrude from the positioning trough of the corresponding base. Thus, the assembling process of the heat dissipating device is also made easier.
