Description

Electronic device

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

At present, electronic devices such as e-sports pens require powerful heat dissipation due to high performance requirements. A known way is to increase the number of fans in the electronic device to quickly blow away the high temperatures that accumulate on the heat sink.

The conventional method can transfer the high temperature of the Central Processing Unit (CPU)/Graphics Processing Unit (GPU) through the heat sink to transfer the heat accumulated on the surface of the CPU/GPU. However, because the electronic components in the body are placed in the vicinity of the CPU/GPU, the high temperature generated by the CPU/GPU is likely to accumulate heat in the dead angle of the wind flow path, so the heat dissipation efficiency is usually compromised.

Incidentally, the fourth vent 129b may be further disposed at the sixth portion 127c such that the second vent 123b and the fourth vent 129b form a second escaping 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 setting of the foot pad 140 allows the electronic device 100 to be firmly placed on the table to avoid dumping.

The electronic device 100 further includes a heat sink 150 disposed on the motherboard 124, wherein the heat sink 150 may be disposed on the first surface 124a or the heat sink 150 may be disposed on the second surface 124b; or may be disposed on the first surface 124a and A heat sink 150 is disposed on the second surface 124b. The heat sink 150 is used to contact the central processing unit 126 or the display card 128 to further dissipate heat generated by the operation of the central processing unit 126 or the display card 128 by conduction.

In addition, the electronic device 100 may further include a fan 160 disposed on the motherboard 124, wherein the fan 160 may be disposed on the first surface 124a or the fan 160 may be disposed on the second surface 124b; or may be on the first surface 124a and A fan 160 is disposed on both surfaces 124b.

Referring to FIG. 1 , FIG. 2 and FIG. 3 simultaneously, when the electronic device 100 is used, the user places the electronic device 100 on the desktop, and the electronic device 100 can be firmly 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 display card 128 due to operation may accumulate, and when heat is accumulated at the central processing unit 126 or the display card 128, the operation of the central processing unit 126 or the display card 128 may be affected. Moreover, the operation of electronic components (not shown) disposed around the central processing unit 126 or around the display card 128 may be affected.

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 disposed in front of the electronic device 100 (on the side closer to the user). The central processing unit 126 and the display card 128, which generate heat by cooling in the casing 122, allow the central processing unit 126 and the display card 128 to be cooled to maintain good operation.

In detail, the first vent 123a and the third vent 129a form a first escaping passage, and the central processing unit 126 is disposed in the first escaping passage, wherein when the central processing unit 126 generates heat due to operation, The generation of natural convection can introduce the first airflow A1 from the outside of the casing 122 via the first vent 123a, and the first airflow A1 flows through the central processing unit 126 in the first escaping passage to carry away the accumulation in the central processing unit 126. After the heat at the place, 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, the second vent 123b can be generated by the natural convection. The second airflow A2 is introduced from the outside of the casing 122, and the second airflow A2 flows through the display card 128 in the second dissipation passage to take away the heat accumulated at the display card 128, and 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 individual independent channels. That is to say, under ideal conditions, the first airflow A1 flowing in the first dissipating passage and the second airflow A2 flowing in the second dissipating passage do not affect each other unless the designer intentionally changes the first airflow using the structural design. The flow path of A1 or second airflow A2.

In addition, the heat sink 150 and the fan 160 can be used more in combination to remove heat by forced convection.

It can be seen from the above that the central processing unit 126 and the display card 128 are disposed in the casing 122 in separate spaces, and the possibility of preventing the heat generated by the two from being accumulated together may also be corresponding to each other. The heat dissipating component dissipates heat in a separate 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 opposite surfaces of the motherboard, so that the central processing unit and the display card are respectively located in independent spaces, so that both can be avoided. The generated heat accumulates in the same space and is difficult to dissipate to improve heat dissipation efficiency.

In addition, in response to such a configuration, vents are provided in both the upper and lower casings to allow the central processing unit and the display card to have individual heat dissipation channels, thereby more effectively improving heat dissipation efficiency.
