Disclosure of Invention

The present invention is directed to an electronic device, in which air blown by a plurality of fans does not interfere with each other to cause turbulence, so that the heat dissipation effect of the electronic device can be effectively improved.

The invention provides an electronic device which comprises a shell, a heating element, a plurality of fans and a guide structure. The housing has a first outlet. The heating element is arranged in the shell. The fans are arranged in the shell and each fan is provided with a second outlet which at least partially faces the interior of the shell. The guide structure is arranged in the shell and at least partially positioned between the fans, and at least partially extends towards the first outlet.

In the invention, the air blown out from the fan is guided by the guide structure to flow through the heating element first, so that the heat of the heating element is taken away along with the air flowing through the heating element, and the heated air leaves the shell through the first outlet, so that the heat generated by the heating element during operation can be effectively discharged out of the shell, namely the electronic device. That is to say, the electronic device can effectively and pertinently improve the heat dissipation effect of the heating element. In addition, the heat dissipation mode of matching the fan and the guide structure does not increase the thickness of the electronic device, and is beneficial to keeping the slim appearance design of the electronic device.

In the invention, because the guide structure is at least partially positioned between the fans, air blown by the two fans cannot interfere with each other to cause turbulent flow, thereby effectively improving the heat dissipation effect of the electronic device.

Detailed Description

In the following description, numerous implementation details are set forth in order to provide a thorough understanding of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner. And features of different embodiments may be applied interactively if possible to implement.

Fig. 1 is a schematic perspective view of an electronic device 100 according to an embodiment of the invention. In the present embodiment, as shown in fig. 1, the electronic device 100 includes a housing 110, and the housing 110 has a first outlet 111. In an embodiment, the electronic device 100 may be a heat dissipation base dedicated for a notebook computer or a heat dissipation base dedicated for a high-performance notebook computer for a computer competition project, but the invention is not limited thereto.

Referring to fig. 2, a perspective view of the electronic device 100 of fig. 1 is shown. In this embodiment, the electronic device 100 further includes at least one heat generating element 120, a plurality of fans 130, and at least one guiding structure 140. For example, as shown in fig. 2, the number of the fans 130 is two. The heating element 120 is disposed in the housing 110, and the fan 130 is also disposed in the housing 110. The fans 130 respectively have second outlets 131, and the second outlets 131 are configured to allow air to be blown out from the corresponding fans 130.

It should be noted that the second outlets 131 of the two fans 130 are respectively at least partially directed toward the inside of the casing 110, so that the fans 130 blow air out of the inside of the electronic device 100. The guiding structure 140 is disposed in the casing 110 and at least partially located between the fans 130, and the guiding structure 140 at least partially extends toward the first outlet 111 of the casing 110 to guide the air blown from the fans 130 to flow through the heat generating elements 120 and then leave the casing 110 through the first outlet 111.

When the user operates the electronic device 100, the heat generating element 120 is operated to generate heat. As described above, the air blown from the fan 130 is guided by the guiding structure 140 and flows through the heating element 120 first, so that the heat of the heating element 120 is carried away with the air flowing through the heating element 120, and the heated air leaves the housing 110 through the first outlet 111, so that the waste heat generated by the heating element 120 during operation can be effectively discharged out of the housing 110, i.e., the electronic device 100.

Moreover, the heat dissipation method by the fan 130 and the guiding structure 140 does not increase the thickness of the electronic device 100, which is helpful for keeping the slim design of the electronic device 100.

Structurally, the guiding structure 140 includes a guiding portion 141, and the guiding portion 141 and the fan 131 together define a chamber C. Specifically, the chamber C is surrounded by the guiding portion 141 and the fan 131, and the heat generating element 120 is located in the chamber C.

Furthermore, the guiding structure 140 includes an extending portion 142, the extending portion 142 is connected to the guiding portion 141, and the extending portion 142 extends toward the first outlet 111 of the housing 110 to divide the chamber C into two sub-chambers CS. More specifically, the heating element 120 is located in one of the sub-chambers CS, and the first outlet 111 of the housing 110 communicates with the sub-chamber CS.

In one embodiment, as shown in fig. 2, the extension 142 of the guiding structure 140 is at least partially located between the two fans 130, and the second outlet 131 of each of the two fans 130 communicates with the corresponding sub-chamber CS and faces at least partially the guiding structure 140. Thus, when the user operates the electronic device 100, the fan 130 draws in the air outside the housing 110 from the first inlet 132 and blows out the air from the second outlet 131, and the air blown out from the second outlet 131 flows through the heating element 120 under the guidance of the guiding portion 141 of the guiding structure 140, and then flows to the first outlet 111 of the housing 110 under the guidance of the extending portion 142 to leave the housing 110.

As described above, since the extension portion 142 of the guiding structure 140 is at least partially located between the two fans 130, the air blown by the two fans 130 will not interfere with each other to cause turbulence, and thus the heat dissipation effect of the electronic device 100 can be effectively improved.

Structurally, the extension portion 142 of the guide structure 140 is located between the guide portion 141 of the guide structure 140 and the first outlet 111 of the housing 110. To further stabilize the gas flow in the sub-chamber CS, the extension 142 of the guiding structure 140 extends in a direction perpendicular to the first outlet 111 of the housing 110. As a result, the chance of turbulence in the sub-chamber CS is further reduced.

In addition, in the present embodiment, as shown in fig. 1 to 2, the fan 130 has a first inlet 132, the first outlet 111 of the housing 110 and the first inlet 132 of the fan 130 are coplanar with each other, and the first inlet 132 of the fan 130 is disposed to allow air to enter the corresponding fan 130. Specifically, the first inlet 132 of the fan 130 is located at the same outer surface of the case 110 as the first outlet 111 of the case 110. Further, the first outlet 111 of the housing 110 is located between the first inlets 132 of the fans 130 corresponding to the chambers C located between the fans 130.

On the other hand, the electronic device 100 further includes other components that generate heat, such as the heat generating component 125. As shown in fig. 2, the heat generating component 125 is also disposed in the housing 110, and the heat generating component 125 is connected to the fan 130 near the first inlet 132 thereof through the heat conducting pipe 150. Specifically, when the user operates the electronic device 100, the heat generated by the heat generating element 125 is at least partially transmitted to the position of the fan 130 close to the first inlet 132 through the heat conducting pipe 150, so that when the air enters the fan 130 through the first inlet 132, the temperature of the heat conducting pipe 150 raised by the heat generating element 125 is effectively reduced, thereby helping to improve the heat dissipation effect of the heat generating element 125.

Furthermore, as mentioned above, the heat of the heat generating element 125 is also carried away with the air flowing through the heat generating element 125, and the heated air leaves the housing 110 through the first outlet 111, so that the heat generated by the heat generating element 125 during operation can be effectively discharged out of the housing 110, i.e. the electronic device 100.

Please refer to fig. 3 and 4. Fig. 3 is a schematic perspective view of an electronic device 100 according to another embodiment of the invention. Fig. 4 is a perspective view of the electronic device 100 of fig. 3. In the present embodiment, as shown in fig. 3 and 4, the fan 130 has a first inlet 132 and a second inlet 133, the first outlet 111 of the housing 110 and the first inlet 132 of the fan 130 are coplanar with each other, the second inlet 133 of the fan 130 is perpendicular to the corresponding first inlet 132, and the second inlet 133 is also configured to allow air to enter into the corresponding fan 130.

Specifically, the first inlet 132 and the second inlet 133 of the fan 130 are respectively located on two adjacent outer surfaces of the housing 110 perpendicular to each other. In this way, the fan 130 can draw air into the casing 110 in two different directions, which is helpful to improve the heat dissipation effect of the electronic device 100.

In summary, in the invention, since the extending portion of the guiding structure is at least partially located between the fans, the air blown by the two fans will not interfere with each other to cause turbulence, and thus the heat dissipation effect of the electronic device can be effectively improved. And in order to further stabilize the airflow in the sub-chamber, the extension direction of the extension part of the guide structure is perpendicular to the first outlet of the shell. Thus, the chance of turbulence in the subchambers is further reduced.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
