[Embodiment] [0008] Please refer to FIG. 1, which is a perspective view of an electronic device 100 according to a preferred embodiment. The electronic device 100 includes a main body 10 and a cover 20 that is coupled to the main body 10. The electronic device 100 can be a disc playback device, a portable computer, or the like. In the present embodiment, the electronic device 100 is described by taking a portable computer as an example. The main body 10 can be a computer main body, and the cover 20 can be a monitor. The side of the cover 20 opposite to the main body 10 is provided with a display function. Display screen 2 [0009] Referring to FIG. 2 and FIG. 3 together, the main body 10 is substantially rectangular parallelepiped, and is composed of a top wall 11, a bottom wall 12 and a plurality of side walls 14 which are fast-connected to the bottom wall 12. And a circuit board component 15 disposed in the housing, a heat sink 16 mounted on the circuit board component 15, and a prompting device 18 (shown in FIG. 5). The top wall 11 has a rectangular cutout 112. The notch 112 extends along the length of the top wall 11 and is adjacent to the side of the body 10 that is rotatably coupled to the cover 20. [0010] The circuit board component 15 includes a circuit board 152 and an electronic component 153 mounted on the circuit board 152. The circuit board 152 may be a motherboard of the electronic device 100 in some embodiments, and the electronic component 153 may be a central processing of the electronic device 100. The electronic component 153 releases waste heat during operation. [0011] The heat sink 16 includes a heat pipe 161, 100102401 attached to the electronic component 153. Form No. A0101 Page 4 of 16 1002004304-0 201232234 [0012] [0014] [0015] The heat dissipating body 163 thermally connected to the heat pipe 161, the wind power device 165 for supplying a forced air flow to the heat radiating body 163, and the retractable air bag 167 for reacting the wind pressure of the wind power device 165. The heat transfer pipe 161 is substantially in the shape of an "S" flat ribbon. The heat pipe 161 is adjacent to the side wall 14 and the other end is connected to the middle of the heat sink 163. The middle portion of the heat pipe 161 is attached to the electronic component 153 for absorbing the waste heat released by the electronic component 153 and transferring heat to the heat sink. 163. A fixing bracket 162 is further disposed at one end of the heat pipe 161 near the heat radiating body 163 for mounting the wind power device 165. The holder 162 is substantially annular. The heat radiating body 163 is disposed on the bottom wall 12 at a position corresponding to the notch 112. The heat dissipating body 163 is substantially rectangular parallelepiped and includes a plurality of metal sheets having good thermal conductivity formed in parallel spaced intervals. Wind power unit 165 is generally circular and is secured within mounting bracket 162. In the present embodiment, the wind power unit 165 is a centrifugal fan. The forced air flow generated by the wind power unit 165 during the rotation is blown toward the heat radiating body 163 to improve the heat dissipation efficiency of the heat radiating body 163, and a part of the air current enters the air bag 167 to expand the air bag 167. In the present embodiment, the wind power unit 165 is electrically connected to the circuit board component board component 15, and the rotational speed of the wind power unit 165 can be adjusted in accordance with the amount of heat generated by the electronic component 153. In the present embodiment, the amount of heat generated by the electronic component 153 is proportional to the rotational speed of the wind power unit 165. The air bag 167 is a retractable air bag which is substantially rectangular parallelepiped and has arcuate ends at both ends. The air bag 167 is disposed on the bottom wall 12, and a portion thereof is exposed by the notch 112. The bottom of the air bag 167 has a rectangular air inlet 1671. The air bag 167 is sleeved on the air inlet 1671 and communicates with the air inlet 1671. Air inlet 100102401 Form No. 1010101 Page 5 of 16 1002004304-0 201232234 1671 is disposed at the junction of the heat pipe 161 and the heat sink 163, and partially inserted into the heat sink 163. Airflow can enter the air bag 167 through the air inlet 1671. In the present embodiment, the air bag 167 may be made of a translucent elastic material, and an indicator light 1 673 may be disposed therein. When the air bag 167 is stretched and bulged, the air bag 167 is thinned, and thus the light transmittance is increased. The change in wind pressure can be observed from the change in the transmittance of the airbag 167. In the present embodiment, the indicator light 1 673 is an LED. [0018] Referring to FIG. 4 and FIG. 5 together, the prompting device 18 includes a detecting unit 181, a comparing unit 183, and a prompting unit 185. The detecting unit 181 is for detecting the pressure at the time of inflation of the airbag. In the present embodiment, the detecting unit 181 is a sensor 1812 provided on the side wall at the notch 112. The sensor 1812 is a pressure sensor for rotating different sensing signals depending on the pressure. In the present embodiment, the top wall 11 is provided with two sensors m2 spaced apart on the side wall of the joint between the main body 10 and the lid body 20. In other implementations, a plurality of sensors 1812 can be placed in other locations. The comparison unit 183 has a preset value for comparing the sensing signal with a preset value. When the sensing signal is greater than the preset value, the comparing unit 183 outputs the control signal. In other embodiments, the preset values can be set according to the needs of the user. The prompting unit 185 is configured to receive the control signal and generate a prompt signal. In this embodiment, the prompt information is a warning dialog displayed in the display screen 21. In other embodiments, the prompt information may also be a combination of sound, picture or vibration, or a combination of two or more thereof. 100102401 Form No. A0101 Page 6 of 16 1002004304-0 201232234 [0020] When the electronic device 100 is in operation, the electronic component 153 generates heat, and the heat pipe 161 transfers heat to the heat sink 163. The wind power unit 165 rotates to provide a forced air flow to the heat sink 163, and the heat sink 163 dissipates heat. At the same time, part of the airflow enters the air bag 167 through the air inlet 1671. The air bag 167 is bulged outward from the notch 112 by the action of the gas, and the user can understand the working state of the current electronic component 153 according to the change of the air bag 167. When the amplitude of the airbag 167 is large, the user can know that the amount of heat generated by the electronic component 153 is increased at this time, and it is necessary to pay attention to whether the electronic device 100 is in an overload state. [0021] In addition, when the air bag 167 is bulged, the compression sensor 1812 generates a sensing signal, and the sensor 1812 transmits the sensing signal to the comparing unit 183. The comparing unit 183 compares the sensing signal with a preset value. When the sensing signal is greater than the preset value, the comparing unit 183 outputs the control signal to the prompting unit 185, so that the prompting information is displayed on the display screen 21, indicating that the heat dissipation is poor, and the electronic device 100 is in an overload state. [0022] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention. Any equivalent modifications or variations made by the person skilled in the art of the present invention should be included in the following patent application.
