Description

Technical Field

[0001] This utility model relates to an electronic device, and more particularly to an electronic device including an air guide. Background Technology

[0002] Generally, servers contain high-heat-generating components such as the central processing unit (CPU) and fans to cool the CPU. When the fans operate, they guide airflow through the CPU and expel the cooled air. However, because servers typically contain multiple electronic components, these components can not only affect the airflow but also the exhaust of cooled air. If the server cannot expel the cooled air, it will accumulate inside, thus affecting the cooling efficiency of the fans. Therefore, it is usually necessary to add an air duct inside the server to guide the cooled airflow smoothly out of the server.

[0003] However, with the miniaturization of servers, the air ducts located inside the server prevent the effective use of internal space. Therefore, the problem that this invention aims to solve is how to exhaust heat dissipation airflow without using an air duct, without affecting the cooling efficiency of the fan.

[0025] In this embodiment, the electronic device 10 includes a housing 100, an electronic component 200, a heat sink 300, and an air guide 400.

The accommodating space S1 is located between the top surface S2 and the bottom surface S3. The distance D1 between the air outlet G2 and the bottom surface S3 is greater than the distance D2 between the air outlet G2 and the top surface S2.

[0026] In this embodiment, the main shell 110 may further include an upper shell 111 and a lower shell 112. The upper shell 111 and the lower shell 112 are assembled to surround the accommodating space S1, with the top surface S2 located on the upper shell 111 and the bottom surface S3 located on the lower shell 112.

[0027] Electronic component 200 is located in the accommodating space S1 of housing 100 and includes a circuit board 210 and a heat source 220. The heat source 220 is disposed on the circuit board. Heat sink 300 is located in the accommodating space S1 of housing 100 and is thermally coupled to heat source 220.

[0028] In this embodiment, the heat sink 300 may be, for example, a heat dissipation fin assembly. The heat sink 300 may include a first heat dissipation fin portion 310 and a second heat dissipation fin portion 320, and the distance D3 between a bottom of the first heat dissipation fin portion 310 and the bottom surface S3 is smaller than the distance D4 between a bottom of the second heat dissipation fin portion 320 and the bottom surface S3. Because the gap between the bottom of the second heat dissipation fin portion 320 and the bottom surface S3 is larger, electrical connections to the circuit board 210 can pass through the gap and connect to the outside.

[0029] An air guide 400 is connected to the rear housing 120 and located between the rear housing 120 and the radiator 300. It includes a first air guide vane 410 and two second air guide vanes 420.

The first air guide vane 410, the two second air guide vanes 420, and the housing 100 together constitute the air guide channel C1, which connects to the air outlet G2. Detailed construction of the air guide 400 will be described later. In this embodiment, the air guide 400 can be secured to the rear housing 120 by multiple fasteners (not shown), such as multiple screws.

[0030] In this embodiment, the electronic component 200 may further include at least one fan 500, which is located in the accommodating space S1 of the housing 100.

[0032] Please see Figure 5 . Figure 5 This is a perspective view of the air guide component according to an embodiment of the present invention.

[0033] In this embodiment, the air guide 400 may further include two reinforcing portions 430. The two reinforcing portions 430 are respectively vertically disposed at one end of the two second air guide vanes 420, and the two reinforcing portions 430 extend toward each other. The two reinforcing portions 430 are used to make the air guide 400 more securely fixed between the rear shell 120 and the radiator 300.

[0034] In this embodiment, the air guide 400 may further include two extensions 440. The two extensions 440 are respectively connected to and parallel to the two second air guide vanes 420, and the two extensions 440 extend to both sides of the radiator 300, so that the radiator 300 is located between the two extensions 440. The lengths of the two extensions 440 may be different.

[0035] Please see Figure 6 . Figure 6 for Figure 1 A magnified perspective view.

[0036] In this embodiment, the protective member 600 may further have at least one hook-shaped structure F2. The rear shell member 120 may further have at least one positioning hole G5.

[0037] The electronic device according to the above embodiment, in addition to adding a wind guide between the rear casing and the heat sink, also includes a protective component on the outside of the electronic device. In this way, without using a wind guide cover, the heat dissipation airflow can be exhausted to the external space, allowing for effective use of the internal space of the server electronic device to achieve miniaturization, reducing the risk of skin burns from accidental contact with the casing, and complying with electromagnetic protection standards.

[0038] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention.
