Description

Heat dissipation module and electronic device for removing dust on heat dissipation fins by means of vibration

technical field

The invention relates to a heat dissipation module, in particular to a heat dissipation module which uses vibration to remove dust on heat dissipation fins.

Background technique

In today's modern information society, the computer system has become one of the indispensable information tools for most people. Regardless of whether it is a desktop personal computer, a notebook personal computer or a server, etc., its operating clock is getting higher and higher, and the application The levels are also getting wider. Today's notebook computers are developing towards thinner and lighter. However, with the advancement of technology, the functions of notebook computers are becoming more and more powerful, so the heat generated when performing various functions is also relatively increased. This is caused by If the heat generated by the internal components of the notebook computer cannot be efficiently removed, it will affect the functional operation and computing speed of the notebook computer.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a heat dissipation module 12 of a conventional notebook computer 10 . The notebook computer 10 includes a housing 14 for covering internal components, and an air outlet 18 is disposed on a side of the housing 14 for exhausting hot air flowing through the cooling module 12 to the outside of the housing 14 . The cooling module 12 of the notebook computer 10 includes a fan 20 installed above an air inlet (not shown in the figure), and a heat sink 22 installed on the fan 20 and the air outlet 18 of the housing 14 In between, a plurality of heat dissipation fins 24 are provided on the heat dissipation groove 22 to increase the surface area for heat dissipation. The fan 20 of the heat dissipation module 12 can suck in the outside air through the air inlet, and discharge the sucked air to the plurality of heat dissipation fins 24 of the heat dissipation groove 22, and finally discharge it through the air outlet 18, so as to clean the internal components of the notebook computer 10. The generated heat is discharged out of the casing 14 through heat convection.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram of a conventional notebook computer 10 using a filter 26 to block the dust inhaled by the fan 20 through the air inlet from blowing into the cooling fins 24 . Because the dust is often sucked by the fan 20 through the air inlet, and then blown to the heat dissipation fins 24, a lot of dust is often accumulated on the heat dissipation fins 24, especially the dust accumulation near the junction of the fan 20 and the heat dissipation fins 24 is more serious. . As shown in FIGS. 1 and 2 , therefore, one solution is to install a filter 26 at the junction between the fan 20 and the cooling fins 24 to block the dust inhaled by the fan 20 through the air inlet from blowing into the cooling fins 24 . However, after the notebook computer 10 has been used for a long time, a large amount of dust will also accumulate on the filter screen 26. If the user has not removed the dust stuck in the filter screen 26, it will cause hot air to be difficult to be discharged from the air outlet 18. The heat generated by the internal components of the notebook computer 10 is not easy to dissipate, which will cause the temperature of the notebook computer 10 system to rise rapidly, which will affect the stability of the notebook computer 10, which may cause a so-called thermal crash, or even reduce the temperature of the notebook computer 10. The useful life of the internal components of the notebook computer 10. However, general users do not know how to disassemble the housing 14 of the notebook computer 10 to remove the filter screen 26 to clean the dust, or simply forget the setting of the filter screen 26, so the existing method of utilizing the filter screen 26 to filter dust is realized. Not for a humanized design.

Detailed ways

Please refer to FIG. 3 . FIG. 3 is a schematic view of the internal components of an electronic device 50 of the present invention. The electronic device 50 includes a housing 52 for covering the internal components. An air outlet 56 is provided on the side of the housing 52 . The device 50 further includes a heat dissipation module 58, which includes a fan 60 installed above an air inlet (not shown in the figure), and a base 62 installed between the fan 60 and the air outlet 56 of the housing 52 . The base 62 can be a heat sink, and the base 62 is provided with a plurality of heat dissipation fins 64 to increase the surface area for heat dissipation. The fan 60 of the cooling module 58 can inhale outside air through the air inlet, and output the inhaled air to a plurality of cooling fins 64 on the base 62, and finally discharge it through the air outlet 56, so as to dissipate the air contained in the internal components of the electronic device 50. The generated heat is discharged out of the casing 52 through heat convection. The electronic device 50 further includes a vibration module 66, which is installed on the base 62 and is used to vibrate a plurality of cooling fins 64 to remove dust on the plurality of cooling fins 64.

The logic unit 70 is installed in the casing 52 and used to control the movement of the vibration module 66 . The vibrator 72 can be a vibrating motor or other components that can generate vibration, and the motor control interface 74 is electrically connected to the logic unit 70 and the vibrator 72 for controlling the vibrator 72 according to the control signal sent from the logic unit 70 Actions.

The logic unit 70 can activate or deactivate the vibrator 72 by inputting a control signal to the motor control interface 74 of the vibration module 66 , and adjust the vibration amplitude of the vibrator 72 of the vibration module 66 by controlling the current input to the vibration module 66 . For example, after the electronic device 50 is turned on, the logic unit 70 controls the fan 60 of the cooling module 58 to start, and at the same time, the logic unit 70 outputs a control signal to the motor control interface 74 of the vibration module 66 to start the vibrator 72 to rotate vibration, and since the vibrator 72 and the heat dissipation fins 64 are installed on the base 62, the vibration generated by the vibrator 72 can be transmitted to the heat dissipation fins 64 through the base 62, so that the heat dissipation fins 64 also produce corresponding vibrations In this way, it can not only effectively prevent dust from dusting on the heat dissipation fins 64, but also shake off the dust previously accumulated on the heat dissipation fins 64 in a vibrating manner, and then exhaust the inhaled air to the base through the fan 60 A plurality of heat dissipation fins 64 on the heat dissipation fins 62 are used to discharge the dust on the heat dissipation fins 64 from the air outlet 56 . Therefore, the function of the vibrator 72 is to drive the cooling fins 64 to vibrate correspondingly, so that the dust is not easy to be deposited on the cooling fins 64, so that the heat dissipation effect of the cooling fins 64 will not be affected, and the cooling fins 64 will not be affected.
