Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

First, in the embodiments shown herein, terms and acronyms such as heat dissipation opening, air outlet or air inlet, etc. are given as examples for convenience of description, and should not limit the present application in any way. This application is not intended to exclude the possibility that other terms may be defined in existing or future protocols to carry out the same or similar functions.

Second, the first, second and various numerical numbers in the embodiments shown below are merely for convenience of description and are not intended to limit the scope of the embodiments of the present application. For example, different preset thresholds are distinguished. In the embodiments of the present application, ordinal numbers such as "first", "second", and the like are used to distinguish a plurality of objects, and are not used to limit the order, sequence, priority, or importance of the plurality of objects. For example, the first preset threshold, the second preset threshold, etc. are only used for distinguishing different preset thresholds, and do not indicate that the importance degree of the preset thresholds is different.

Third, in the embodiments illustrated herein, "plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, and c, may represent: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, wherein a, b and c can be single or multiple.

The heat sink may be an electronic device such as a mobile phone, a tablet, or a Personal Computer (PC), and may also be referred to as a terminal device. For example, heat dissipation devices in electronic devices may generally include thermally conductive copper sheets, heat dissipation aluminum sheets, fans, and heat sinks. The heat-conducting copper sheet can transfer heat generated in operation of a Central Processing Unit (CPU), a Graphic Processing Unit (GPU) and the like in the electronic equipment to the heat-radiating aluminum sheet, and then the fan blows air towards the heat-radiating aluminum sheet, so that the heat can enter the external environment through the heat-radiating port, and the purpose of heat radiation of the electronic equipment is achieved.

In many application scenarios, however, there is often a situation where the heat dissipation opening is blocked. Illustratively, the heat dissipation opening is blocked by foreign matter, or covered with other substances, and the like. Under the condition that the heat dissipation opening is blocked, heat generated by the heat dissipation device cannot be diffused to the external environment through the heat dissipation opening, so that the temperature of the heat dissipation device is too high, and the performance of the heat dissipation device is affected.

In view of this, embodiments of the present application provide a heat dissipation apparatus and a heat dissipation method, a wind speed and direction detector is disposed near an air outlet and an air inlet to detect a wind speed value and a wind direction value of the air outlet and the air inlet, the detected wind speed value and wind direction value are sent to a processor, and the processor determines whether the air outlet and/or the air inlet is blocked according to a preset threshold, so as to prompt a user to clean the air outlet and/or the air inlet.

The heat dissipation device provided by the embodiment of the present application is described in detail below with reference to fig. 1.

Fig. 1 illustrates a heat dissipation apparatus 100 according to an embodiment of the present application. As shown in fig. 1, the apparatus 100 includes: the air outlet 110, the air inlet 120, the processor 130, the wind speed and direction detector 140, and the wind speed and direction detector 150. The wind speed and direction detector 140 is disposed near the wind outlet 110, the wind speed and direction detector 150 is disposed near the wind inlet 120, and the wind speed and direction detector 140 and the wind speed and direction detector 150 are connected to the processor 130.

The wind speed and direction detector 140 is configured to detect a wind speed and a wind direction of the air outlet 110, and send a detected wind speed value and a detected wind direction value to the processor 130. And a wind speed and direction detector 150 for detecting a wind speed and a wind direction of the wind inlet 120 and transmitting the detected wind speed and wind direction values to the processor 130.

The processor 130 is configured to receive the wind speed value and the wind direction value sent by the wind speed and direction detector 140, and receive the wind speed value and the wind direction value sent by the wind speed and direction detector 150. The processor 130 is further configured to: when the wind speed value and the wind direction value satisfy at least one of the following conditions, prompting the user to clean the air outlet 110 and/or the air inlet 120:

the wind speed value of the wind outlet is less than or equal to a first preset threshold value; the wind direction value of the wind outlet is greater than or equal to a second preset threshold value and less than or equal to a third preset threshold value; the wind speed value of the wind inlet is less than or equal to a fourth preset threshold value; or the wind direction value of the wind inlet is greater than or equal to a fifth preset threshold value and less than or equal to a sixth preset threshold value.

The heat dissipation device provided by the embodiment of the application is used for detecting the wind speed and the wind direction of the air outlet and the air inlet by arranging the wind speed and wind direction detectors near the air outlet and the air inlet, sending the detected wind speed value and the detected wind direction value to the processor, comparing and judging the obtained wind speed value and the obtained wind direction value according to the preset threshold value through processing, and determining the cleaning information prompted to a user. The heat dissipation device can remind a user in time when the air outlet and/or the air inlet are blocked, so that the air outlet and/or the air inlet can be dredged in time by the user, the temperature of the heat dissipation device is reduced, and the performance of the heat dissipation device is further improved.

The wind speed and direction detector in the embodiment of the application comprises a detected point and a plurality of sensors. The plurality of sensors may be ultrasonic sensors or other sensors capable of emitting signals, the detected point may be a housing of the heat dissipation device or other devices in the heat dissipation device or other devices reintroduced, and the application is not limited to the type of the sensor and the type of the detected point.

The working principle of the wind speed and direction detector is described below.

The wind speed and direction detector comprises a plurality of sensors, a wind speed and direction detector and a plurality of sensors, wherein the sensors in the wind speed and direction detector respectively send directional detection signals (for example, ultrasonic waves), the detection signals are reflected after contacting detected points, namely the detection signals are reflected by the detected points, and the sensors receive the detection signals returned by the detection signals sent by the sensors respectively, so that the wind speed and the wind direction on the detection paths can be calculated according to the transmission delay (the paths between the sensors and the detected points form the paths) on the paths and the direction difference of the paths (namely the wind speed and the wind direction of the deployment position of the detector can be determined).

Ultrasonic anemometry is an application of ultrasonic detection technology in a gas medium, and is used for measuring wind speed by utilizing the influence of the propagation speed of ultrasonic waves in air due to air flow (wind). This is because the speed of sound in air is superimposed by the velocity of air flow in the wind direction. If the propagation direction of the ultrasonic wave is the same as the wind direction, the propagation speed of the ultrasonic wave is accelerated; conversely, if the propagation direction of the ultrasonic wave is opposite to the wind direction, the propagation speed of the ultrasonic wave is reduced.

Fig. 2 shows a block diagram of a wind speed and direction detector. As shown in fig. 2, the wind speed and direction detector includes an ultrasonic sensor 1, an ultrasonic sensor 2, an ultrasonic sensor 3, and a detected point. The three ultrasonic sensors respectively send ultrasonic waves to the detected point, after the ultrasonic waves reach the detected point, ultrasonic signals can be returned to reach the corresponding ultrasonic sensors, and at the moment, the ultrasonic sensors can calculate the wind speed and the wind direction on the detection path according to the time difference (namely transmission time delay) between the time when the ultrasonic waves are sent and the time when the ultrasonic waves are received and the direction difference of each path of the three sensors.

It should be understood that the wind speed value represents the flow rate of air, generally in m/s, and the wind direction value is generally expressed in an angle, and the circumference is divided into 360 degrees, so that the wind direction value ranges from 0 to 360 degrees.

A schematic wind direction diagram of a notebook computer under various conditions that a heat dissipation port of the notebook computer is not blocked and is blocked will be described in detail with reference to fig. 10 to 16, taking a notebook computer with an air outlet, a main air inlet and a side air inlet as an example.

Fig. 10 shows a structure of a notebook computer. As shown in fig. 10, the notebook computer 1000 includes a display 1010, a hinge 1020 and a keyboard 1030. The display screen 1010 is used for displaying images, characters, dialog boxes and the like, the keyboard 1030 is an instruction and data input device for a user to operate the notebook computer, and the rotating shaft 1020 is used for connecting the display screen 110 and the keyboard 130, so that the user can adjust the display screen 1010 and the keyboard 1030 to form any angle according to own habits, and the notebook computer is convenient for the user to use.

Fig. 11 is a diagram illustrating a bottom heat sink arrangement of the notebook computer 1000. Fig. 10 is a bottom of the notebook computer 1000, i.e., a bottom of the keyboard 1030 of the notebook computer 1000 in fig. 10. As shown in fig. 11, the bottom of the notebook computer 1000 includes an air outlet 1040, an air outlet 1050, a main air inlet 1060, a fan 1070, a fan 1080, a side air inlet 1090, and a side air inlet 1091. Two

air outlets

1040 and 1050 with the same size are disposed along the length direction of the rotating shaft 1020 at the bottom, and the distances from the two air outlets to the symmetric axis 1 of the rotating shaft 1020 are the same. Below the two air outlets, along the length direction of the rotating shaft 1020 at the bottom, a main air inlet 1060 is disposed, and a symmetry axis 2 of the main air inlet 1060 is aligned with a symmetry axis 1 of the rotating shaft 1020. Two fans are disposed inside the main air inlet 1060, wherein one fan 1170 is located at an intersection point of a symmetry axis 3 of the air outlet 1140 and a symmetry axis 5 of the main air inlet 1060, and one fan 1180 is located at an intersection point of a symmetry axis 4 of the air outlet 1040 and the symmetry axis 5 of the main air inlet 1060. A side air inlet 1090 and a side air inlet 1091 are disposed at both sides below the main air inlet 1060.

It should be understood that the air outlet, the main air inlet and the side air inlet in the embodiment of the present application may be grilles, grids or other structures capable of discharging or supplying air, so as to satisfy high efficiency of discharging and supplying air, but prevent impurities from entering.

Fig. 11 is only a disposition of the heat dissipation opening in the embodiment of the present application, and it should be understood that, in practical applications, the positions of the air outlet, the main air inlet, and the fan of the heat dissipation device may have various dispositions, which are not limited in the present application.

Fig. 12 shows an air direction diagram at a heat sink of a notebook computer according to an embodiment of the present application. As shown in fig. 12, in the case where the heat dissipation ports (the air outlet and the air inlet) are not blocked, the wind directions on both sides of the symmetry axis 1 of the rotation shaft 1020 are substantially symmetrical. The fan rotates, and the generated wind blows to the wind outlet from the wind inlet (including the main wind inlet and the side wind inlet). In the case of the fan 1070, when the fan 1070 rotates clockwise, the wind direction of wind generated to be blown around is substantially in the clockwise direction. Similarly, when the fan 1080 rotates clockwise, the wind direction of the generated wind blowing everywhere is also substantially in the clockwise direction.

In the embodiment of the present application, the wind speed in fig. 12 to 16 is indicated by the number of arrows, and the more arrows indicate that the wind speed is faster, the wind direction is indicated by the direction indicated by the arrows. For example, as shown in fig. 12, the wind speed at four arrows is higher than that at three arrows, and the upward arrow indicates that the wind direction is blowing from bottom to top.

It can be understood that if the wind speed and direction detector is disposed between the main air inlet and the air outlet, the wind speed and the wind direction when the main air inlet and the air outlet are not blocked can be detected, and the notebook computer disposed with the wind speed and direction detector can be an example of the heat dissipation device provided in the embodiment of the present application.

As shown in fig. 13, 8 anemometry wind detectors are disposed in the notebook computer, wherein the anemometry wind detector 1 is disposed near the left side of the wind outlet 1040 for detecting wind speed and wind direction at the left side of the wind outlet 1040. A wind speed and direction detector 2 is disposed near the right side of the wind outlet 1040, and is used for detecting the wind speed and direction on the right side of the wind outlet 1040. Anemometry 3 is disposed near the left side of outlet 1050 for detecting the wind speed and direction to the left side of tuyere 1040. An anemometry 4 detector is disposed near the right side of the outlet 1050 for detecting the wind speed and direction on the right side of the outlet 1050. A wind speed and direction detector 5 is disposed near the left side of the main wind inlet 1060 for detecting the wind speed and direction to the left side of the main wind inlet 1060. A wind speed and direction detector 6 is disposed near the right side of the main inlet 1060 for detecting the wind speed and direction to the right side of the main inlet 1060. The wind speed and direction detector 7 is disposed near the side air inlet 1090 to detect the wind speed and direction on the left side of the side air inlet 1090. A wind speed and direction detector 8 is disposed near the main wind inlet 1091 for detecting the wind speed and direction to the left of the side wind inlet 1091.

It should be understood that the wind speed and direction detectors 1 to 8 all have the corresponding preset threshold values of wind speed and direction in the notebook computer. For example, the anemorumbometer 1 detects a set of wind speed and wind direction values, and after the processor obtains the set of values, the processor may obtain a preset threshold corresponding to the anemorumbometer 1 from the memory, so as to perform comparison and determine whether to prompt the user to clean the air outlet on the left side of the air outlet 1040. It is understood that the memory may include preset threshold values of wind speed and wind direction corresponding to the anemometry 1 to anemometry 8, and detection positions corresponding to the anemometry 1 to anemometry 8.
