Description

Adjustable tuyere device and portable electronic device using same

The present invention relates to a tuyere device, and in particular to an adjustable tuyere device for changing the wind direction and a portable electronic device using the same.

Electronic devices such as notebook computers or desktop computers generate a large amount of waste heat when used. In order to increase the heat dissipation effect, a fan and a radiator are usually installed at the air outlet, and the fan is forcibly cooled and exhausted, so that the temperature of the gas discharged from the air outlet is high.

The conventional air outlet has a fixed fence, which cannot change the direction of the heat dissipation airflow, so that long-term use may cause a problem of excessive temperature in a local area. In addition, the fixed fence cannot prevent dust or impurities from entering through the air outlet, causing problems such as internal dust accumulation and is difficult to remove.

The present invention relates to an adjustable tuyere device and a portable electronic device using the same, which can adjust the wind direction by adjusting the angle of the blade.

According to one aspect of the present invention, an adjustable tuyere device is provided that is disposed in a housing having an opening. The adjustable tuyere device comprises a plurality of blades, a driving unit and a control unit. The vanes are rotatably disposed at an opening in a first direction. The driving unit is coupled to the blades. The control unit is coupled to the driving unit, and the control unit controls the driving unit according to a fan speed or a computer temperature to drive the blades to turn from the first direction to the second direction.

According to another aspect of the present invention, a portable electronic device is provided, including a housing having an opening, a plurality of blades, a driving unit, and a control unit. The vanes are rotatably and spaced apart from the opening. The driving unit is coupled to the blades. The control unit is coupled to the driving unit, and the control unit controls the driving unit according to a fan speed or a computer temperature to drive the blades to be turned from the first direction to the second direction.

In order to better understand the above and other aspects of the present invention, the preferred embodiments are described below, and in conjunction with the drawings, the detailed description is as follows:

The adjustable tuyere device of the present embodiment and the portable electronic device using the same utilize the rotatable blades and adjust the angle of the blades to change the wind direction at the exit. For example, when the computer is turned on, the angle of the blade rotation is automatically or manually set through the user interface or the software, and the control unit can control the driving unit according to the set value to make the blade face in a predetermined direction or swing.

The following is a detailed description of the embodiments, which are intended to be illustrative only and not to limit the scope of the invention. The portable electronic device of this embodiment may be a notebook computer, a tablet computer, a mobile phone, a satellite navigation device, a camera, or other types of electronic products, which is not limited by the present invention.

Referring to FIGS. 1A and 1B , a schematic diagram of an adjustable tuyere device 101 configured to steer the blade 102 in a portable electronic device 100 is illustrated. The adjustable tuyere device 101 includes a plurality of blades 102, a drive unit 104, and a control unit 106. The blades 102 are spaced apart from each other in the housing One of the openings 112 is at 110. The control unit 106 is coupled to the driving unit 104 and controls the driving unit 104 according to the set value to orient the blade 102 toward a predetermined direction. The set value is, for example, a fan speed, a computer temperature or a control signal. In Fig. 1A, the fan 114 is disposed on one side of the blade 102 and provides a heat flow F for heat dissipation in the direction in which the opening 112 is located. In addition, the tachometer 116 can be disposed in the housing 110 for detecting the rotational speed of the fan 114, and the thermometer 118 is disposed in the housing 110 for detecting the internal temperature of the computer. Therefore, the control unit 106 can control the driving unit 104 according to the detected fan speed or the computer temperature.

For example, in FIG. 1A, when the rotational speed of the fan 114 is less than or equal to a predetermined value (eg, 3000 rpm), the blade 102 is rotatably oriented toward a first direction D1; in FIG. 1B, when the fan 114 is When the rotational speed is greater than a predetermined value (e.g., 3000 rpm), the control unit 106 controls the drive unit 104 in accordance with the fan rotational speed to drive the blade 102 from the first direction D1 to the second direction D2.

Alternatively, in FIG. 1A, when the computer temperature is less than or equal to a predetermined value, the blade 102 is rotatably oriented toward a first direction D1; in FIG. 1B, when the computer temperature is greater than a predetermined value, the control unit 106 is based on the computer The temperature control drive unit 104 drives the blade 102 from the first direction D1 to the second direction D2.

In addition, the control unit 106 can also control the driving unit 104 according to a computer power on or off signal to drive the blade 102 to open or close. For example, when the computer is turned on, the blade 102 is opened to allow the airflow F for heat dissipation to pass through the opening 112, and when the computer is turned off, the blade 102 is closed to prevent dust or impurities from entering the casing 110 through the opening 112.

Moreover, the control unit 106 can also control the driving unit 104 according to a blade rocking signal to drive the blade 102 to sway periodically or irregularly. For example, after the fan 114 is activated, the angle is changed once every predetermined time (for example, 5 minutes) or the angle is changed from time to time. This creation does not limit the timing of the control and the manner in which the blades 102 rotate, as long as the wind direction can be changed to avoid blowing the same direction for a long time.

Next, FIG. 2 is a schematic side view of the adjustable tuyere device 101 according to an embodiment of the present invention. 3A-3C are respectively schematic diagrams showing the operation of the adjustable tuyere device 101 according to an embodiment of the present invention. In FIG. 2, the blades 102 are spaced apart at one of the openings 112 of the housing 110. The driving unit 104 is located in the housing 110. The driving unit 104 can include a link structure 105 and a driver 107. The linkage structure 105 connects the blades 102 and is driven by the drive 107 to drive the blades 102 to steer. The drive 107 is, for example, an electric motor for transmitting power to the linkage structure 105 to cause the linkage structure 105 to move horizontally at the opening 112. This creation does not limit the manner in which the link structure 105 is actuated, as long as the blade 102 can be driven and the angle of the blade 102 can be adjusted.

For example, the linkage structure 105 is, for example, a crank rocker structure. Referring to FIG. 3A, the link structure 105 includes a crank 105a and a rocker 105b. The crank 105a is coupled between the rocker 105b and the driver 107 and moves circumferentially relative to the driver 107. That is, when the driver 107 rotates, the driver 107 drives the crank 105a to perform a circular motion, and when the crank 105a moves in a circular motion relative to the driver 107, The rocker 105b can be driven to move horizontally at the opening 112. In other words, the rocker 105b is horizontally movable between the side wall 111 of the housing 110 and the heat sink 115. In addition, the rocker 105b When the blade 102 is moved horizontally between the side wall 111 and the heat sink 115, the blade 102 can be adjusted to adjust the direction, as shown in FIGS. 3A-3C.

In Figure 3A, the blade 102 closes the opening 112 when the computer is not turned on. In FIG. 3B, when the computer is turned on, the driver 107 is rotated counterclockwise to rotate the blade 102 from the closed position by 45 degrees to the first open position and toward the first direction D1. Next, in FIG. 3C, the driver 107 is rotated counterclockwise to rotate the blade 102 from the first open position by 45 degrees to the second open position and toward the second direction D2 or other direction. Then, when the computer is turned off, the blade 102 closes the opening 112 again to achieve the effect of blocking external pollution. This creation does not limit the angle at which the blade 102 rotates as long as the blade 102 can change direction or sway.

In summary, although the present invention has been disclosed above in the preferred embodiments, it is not intended to limit the present invention. Those who have ordinary knowledge in the technical field of the present invention can make various changes and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application.
