Description

Electronic device

The present invention relates to an electronic device, and more particularly, to an electronic device with good heat dissipation effect.

At present, electronic devices such as gaming laptops require powerful heat dissipation due to high-efficiency requirements. The conventional way is to increase the number of fans in the electronic device to quickly blow away the high temperature accumulated in the heat sink.

Although the conventional method can transfer the high temperature of the central processing unit (CPU) / graphics processing unit (GPU) to the heat transfer of the heat through the heat sink to heat the heat accumulated on the surface of the CPU / GPU, However, because the electronic components in the body are located in the vicinity of the CPU / GPU, the high temperature generated by the CPU / GPU can easily accumulate heat in the dead corner of the air flow path, so the heat dissipation efficiency is usually reduced.

Incidentally, a fourth vent 129b may be further provided in the sixth portion 127c, so that the second vent 123b and the fourth vent 129b form a second dissipation passage.

In addition, the electronic device 100 further includes a pair of foot pads 140 disposed on one of the fifth portion 127b and the seventh portion 127d. Since the fifth portion 127b and the seventh portion 127d have different heights in the vertical direction, the placement of the foot pad 140 can allow the electronic device 100 to be stably placed on the desktop and avoid falling.

The electronic device 100 further includes a heat sink 150 provided on the main board 124, wherein the heat sink 150 may be provided on the first surface 124a or the heat sink 150 on the second surface 124b; or, the first surface 124a and The second surface 124b is provided with a heat sink 150. The heat sink 150 is used for contacting the central processing unit 126 or the display card 128 to further quickly dissipate heat generated during the operation of the central processing unit 126 or the display card 128 through conduction.

In addition, the electronic device 100 may further include a fan 160 provided on the motherboard 124, wherein the fan 160 may be provided on the first surface 124a or the fan 160 on the second surface 124b; or, the first surface 124a and the first surface 124a may be provided. A fan 160 is provided on both surfaces 124b. Through the rotation of the fan 160, heat can be forced out of the casing 122 by means of forced convection.

Please refer to FIG. 1, FIG. 2 and FIG. 3 at the same time. When the above-mentioned electronic device 100 is used, the user places the electronic device 100 on a desktop, and the electronic device 100 can be stably placed on the desktop through the setting of the foot pad 140. . Next, the display screen 110 is turned on with respect to the host 120 and the power of the electronic device 100 is turned on. The heat generated by the central processing unit 126 and the graphics card 128 due to operation will accumulate, and when the heat is accumulated at the central processing unit 126 or the graphics card 128, the operation of the central processing unit 126 or the graphics card 128 will be affected. Furthermore, it will affect the operation of electronic components (not shown) arranged around the central processing unit 126 or around the graphics card 128.

In particular, according to the principle of natural convection, the cooler air outside the electronic device 100 enters the machine through the first vent 123a and the second vent 123b provided in front of the electronic device 100 (the side closer to the user). The casing 122 cools the central processing unit 126 and the display card 128 that generate heat, so that the central processing unit 126 and the display card 128 can be cooled down and can maintain good operation.

In detail, the first vent 123a and the third vent 129a form a first dissipation channel, and the central processing unit 126 is disposed in the first dissipation channel. When the central processing unit 126 generates heat due to operation, it passes through The generation of natural convection can introduce the first airflow A1 from the outside of the casing 122 through the first vent 123a, and the first airflow A1 flows through the central processing unit 126 in the first dissipation channel to take away and accumulate in the central processing unit 126 After the heat is removed, the hot air is discharged from the third vent 129a.

The display card 128 is disposed in the second dissipation channel formed by the second vent 123b and the fourth vent 129b. Therefore, when the display card 128 generates heat due to operation, it can pass through the second vent 123b through the generation of natural convection. After the second airflow A2 is introduced from the outside of the cabinet 122, and the second airflow A2 flows through the display card 128 in the second dissipation channel to take away the heat accumulated at the display card 128, the hot air is discharged from the fourth vent 129b .

It should be noted that the first dissipation channel and the second dissipation channel are separate channels. That is, under ideal conditions, the first air flow A1 flowing in the first dissipating channel and the second air flow A2 flowing in the second dissipating channel do not affect each other, unless the designer intentionally changes the first air flow by using the structural design The flow path of A1 or second air flow A2.

In addition, the radiator 150 and the fan 160 can be used in combination to exhaust heat by using forced convection.

From the above, it can be seen that the central processing unit 126 and the graphics card 128 are arranged in separate spaces in the chassis 122. In addition to the possibility of preventing the heat generated by the two from accumulating together, they can also correspond to each other. The heat dissipation element dissipates heat in an independent heat dissipation channel.

In summary, in the electronic device of the present invention, the central processing unit and the display card are respectively disposed on two opposite surfaces of the motherboard, so that the central processing unit and the display card are respectively located in independent spaces, and the two can be avoided. The generated heat is accumulated in the same space and difficult to dissipate to improve heat dissipation efficiency.

In addition, in accordance with such a setting structure, ventilation openings are provided on the upper and lower casings, so that the central processing unit and the graphics card have individual heat dissipation channels, and the heat dissipation efficiency is more effectively improved.

Although the present invention has been disclosed as above with the examples, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some modifications and retouching without departing from the spirit and scope of the present invention. The protection scope of the present invention shall be determined by the scope of the attached patent application.
