Abstract

An electronic device includes a body and a heat dissipation module. The body includes a display, and the display has a display surface. The heat dissipation module is disposed on the display. The heat dissipation module includes a casing and at least one first fan. The casing has a first opening. The first opening faces the display surface. The first fan is disposed in the casing, and the first fan includes an air inlet portion and an air outlet portion. The air outlet portion faces the first opening, wherein an airflow generated by the first fan flows out of the casing from the air outlet portion via the first opening to flow to the display surface. An ambient air outside the casing flows into the air inlet portion of the first fan via the first opening.

First claim

What is claimed is:

1 . An electronic device, comprising:
a body comprising a display, and the display has a display surface; and a heat dissipation module disposed on the display and comprising:
a casing having a first opening, and the first opening faces the display surface; and
at least one first fan disposed in the casing, wherein the at least one first fan comprises at least one air inlet portion and at least one air outlet portion, the at least one air outlet portion faces the first opening, and an airflow generated by the at least one first fan flows out of the casing after passing through the first opening from the at least one outlet portion to flow towards the display surface,
an ambient air outside the casing flows into the at least one air inlet portion of the at least one first fan via the first opening.

2 . The electronic device of claim 1 , wherein the casing has at least one second opening, and the ambient air outside the casing flows into the at least one air inlet portion of the at least one first fan via the at least one second opening.

3 . The electronic device of claim 2 , wherein an airflow direction of the heat dissipation module flowing in via the at least one second opening is perpendicular to an airflow direction of the heat dissipation module flowing out of the first opening.

4 . The electronic device of claim 2 , wherein an area of the at least one second opening is less than an area of the first opening.

5 . The electronic device of claim 2 , wherein the casing has a first side cover and a second side cover perpendicular to each other, the first side cover is parallel to the display surface and stacked on the at least one air inlet portion of the at least one first fan, the second side cover is extended along a normal direction of the display surface and connected to the first side cover, and the first opening is located at the second side cover.

6 . The electronic device of claim 5 , wherein the casing has a third side cover and a fourth side cover opposite to each other, and the third side cover and the fourth side cover are connected to two opposite sides of the first side cover and perpendicular to the display surface and the second side cover.

7 . The electronic device of claim 6 , wherein the heat dissipation module further comprises two first retaining walls disposed in the casing.

8 . The electronic device of claim 7 , wherein a quantity of the at least one second opening is two, the two second openings are respectively disposed at the third side cover and the fourth side cover, the two first retaining walls are respectively connected to peripheral edges of the two second openings, and the two first retaining walls are respectively inclined to the third side cover and the fourth side cover.

9 . The electronic device of claim 1 , wherein the body further comprises a chassis and a second fan, the chassis is connected to the display and located at an opposite side of the display surface, and the second fan is disposed in the chassis.

10 . The electronic device of claim 9 , wherein the chassis comprises an air inlet and an air outlet, the air outlet is located at an end of the chassis adjacent to the heat dissipation module, and the air inlet is located at another end of the chassis away from the heat dissipation module, wherein an airflow is adapted to flow into the chassis from the air inlet and flow out from the chassis via the air outlet.

11 . The electronic device of claim 9 , wherein the display further comprises an air inlet slot, the air inlet slot is disposed at an outer periphery of the display surface and located between the display surface and the first opening, the display is in an air communication state with the chassis via the air inlet slot, the chassis comprises an air outlet, and the air outlet is located at an end of the chassis away from the heat dissipation module, wherein an airflow is adapted to flow into the body from the air inlet slot and flow out from the chassis via the air outlet.

12 . The electronic device of claim 1 , wherein the at least one first fan is a centrifugal first fan.

13 . The electronic device of claim 1 , wherein the at least one first fan comprises at least one volute and at least one impeller, and the at least one impeller is rotatably assembled in the at least one volute.

14 . The electronic device of claim 1 , wherein a quantity of the at least one air inlet portion is two, and the two air inlet portions are opposite to each other.

15 . The electronic device of claim 1 , wherein a quantity of the at least one first fan is a plurality, and the first fans are arranged parallel to a side of the display surface.

16 . The electronic device of claim 15 , wherein the air outlet portions of the first fans are arranged at intervals with gaps between the air outlet portions, and the ambient air outside the casing flows into the air inlet portions of the first fans from the first opening through the gaps.

17 . The electronic device of claim 1 , wherein the display comprises a frame, the frame surrounds the display surface, and the heat dissipation module is disposed on the frame.

18 . The electronic device of claim 1 , wherein the electronic device is an AIO computer.

19 . The electronic device of claim 1 , wherein the display surface is a touch display surface.

20 . The electronic device of claim 1 , wherein an air outlet angle of the at least one air outlet portion is biased towards the display surface.
