The heat dissipation assembly 10 can be directly installed inside a notebook computer, the heat dissipation assembly 10 is covered with a housing 20 of the notebook computer, one side of the housing 20 far away from the heat dissipation assembly 10 is equivalent to a D-side of the notebook computer, in this embodiment, the housing 20 is provided with an air inlet, and at the same time, the edge of the housing is provided with a first air outlet 200. Further, a square-shaped foam 30 is further disposed between the heat dissipation assembly 10 and the housing 20, and may be a square-shaped foam structure or a foam structure with other shapes as long as the enclosed area is a closed area, it should be noted that the first air inlet 100 and the first air outlet 200 are both disposed in the area enclosed by the square-shaped foam 30, and since the square-shaped foam 30 has a certain thickness, a sealed channel is formed at the square-shaped foam 30 after the housing 20 is mounted, so that the air volume introduced by the first air inlet 100 is guided out from the first air outlet 200 under the limitation of the square-shaped foam 30. In practical implementation, the clip-shaped foam 30 may be first adhered to a surface of the fan housing 12 close to the casing 20 to ensure that the first air inlet 100 is located in an area surrounded by the clip-shaped foam 30, and then the casing 20 is fixed to make the casing 20 and the clip-shaped foam 30 fully contact with each other to compress the clip-shaped foam 30, so as to form a sealed passage.

Specifically, the air guiding groove 50 may be a hollow groove body, the shape of the cross section of the air guiding groove may be rectangular, and the shape of the accommodating groove is matched with the shape of the air guiding groove 50, so that the air guiding groove 50 can be completely placed in the foot pad 40, and the bottom surface of the notebook computer is not influenced in appearance while the air guiding effect is achieved.
Fig. 4 shows a partial schematic view of the air guide groove 50. In this embodiment, a surface of the air guiding groove 50 contacting the housing 20 is a first surface of the air guiding groove 50, and taking the air guiding groove 50 shown in fig. 4 as an example, a bottom surface thereof is the first surface (not shown in fig. 4), and the first surface is provided with a second air inlet (not shown in fig. 4) corresponding to a position of the first air outlet 200 arranged on the housing 20, so as to ensure that air guided out from the first air outlet 200 can directly enter the air guiding groove 50 through the second air inlet. It should be noted that the size of the second air inlet may be greater than or equal to the size of the first air outlet 200, so as to ensure that the air volume can be directly introduced into the air guiding groove 50, and when the air guiding groove 50 is actually designed, the first surface of the air guiding groove 50 may be completely opened to be directly used as the second air inlet.
Correspondingly, the second surface of the air guiding groove 50 is provided with at least one second air outlet 400 for guiding out the air quantity guided by the second air inlet. In this embodiment, the second surface of the air guiding groove 50 is a surface adjacent to the first surface, and it needs to be ensured that the second surface is a surface far away from the inner wall of the accommodating groove, so as to ensure that the air guided out through the second air outlet 400 can flow along the surface of the housing 20, as shown in fig. 5, wherein the arrow direction in fig. 5 is the air flow direction.
It should be noted that, in the present embodiment, all the components and the openings are required to be arranged according to the limit of safety regulations, and for the air guiding duct 50, the height of the at least one second air outlet 400 formed on the second surface thereof is limited to be between 0.5 mm and 1 mm, and is preferably set to be 0.95 mm.
In the embodiment, cold air formed by the heat dissipation assembly passes through the first air inlet 100 formed in the heat dissipation assembly 10, is guided by the zigzag foam 30 and then is discharged from the first air outlet 200, and the air guided out of the first air outlet 200 passes through the air guide groove 50 and then is blown over the outer surface of the bottom surface of the notebook computer, so that the cold air directly blows over a region with higher temperature in the D surface, and the purpose of reducing the temperature of the bottom surface of the notebook computer is achieved.
The second embodiment of the present disclosure also provides a heat dissipation structure for a bottom surface of a notebook computer, on the basis of the heat dissipation structure in the first embodiment, in this embodiment, a wind blocking door 60 is disposed in the wind guiding groove 50, and the disposed position of the wind blocking door corresponds to the first wind outlet 200, so that the wind blocking door can be used for blocking the first wind outlet 200, preventing the wind led in by the first wind inlet 100 from being led out, and closing the heat dissipation structure under the condition of low power consumption or no direct contact of a user on a D surface of the notebook computer.
The heat dissipation structure in this embodiment further includes an extending structure 61 and a contracting structure 62 which are disposed between the air blocking door 60 and the air guiding groove 50, as shown in fig. 6 and 7, and are used for providing extending force and contracting force for the air blocking door 60, the extending force and the contracting force act on the air blocking door 60 in opposite directions, when the contracting force is greater than the extending force, the air blocking door 60 is far away from the first air outlet 200 under the action of the contracting force, so that the first air outlet 200 is opened, thereby achieving the heat dissipation function, when the extending force is greater than the contracting force, the air blocking door 60 is close to the first air outlet 200 or is kept in a state of blocking the first air outlet 200, and achieving the effect of blocking the first air outlet. It should be noted that, the damper door 60 is preferably a cube with a certain thickness, when the damper door 60 is disposed in the air guiding groove 50, one side of the damper door 60 close to the housing 20 is preferably in direct contact with the housing 20, and the size of the side close to the housing 20 is limited to be greater than or equal to the size of the first air outlet 200, so as to ensure that the damper door 60 can completely block the first air outlet 200 when the heat dissipation function is not required to be turned on, as shown in fig. 6.
Specifically, the unfolding structure 61 in this embodiment may use a hydraulic rod or a spring structure, or other mechanisms that have a certain length and can resist the external force to a certain extent without applying the external force, and one end of the unfolding structure is fixed inside the air guiding groove 50, and the other end of the unfolding structure is fixed on the air blocking door 60; the contraction structure 62 may be a thermal memory metal or an electromagnetic contraction device, one end of which is also fixed inside the air guiding groove 50, and the other end of which is also fixed on the damper 60, wherein the electromagnetic contraction device at least comprises a structure with a contraction characteristic or a contraction function, such as an electromagnet or a motor.
When the contraction structure 62 is made of the thermal memory metal, if the ambient temperature exceeds the first threshold, that is, the ambient temperature exceeds the phase transition temperature of the thermal memory metal, the thermal memory metal contracts, and since one end of the thermal memory metal is fixed inside the air guiding groove 50 and cannot move, the thermal memory metal drives the air blocking door 60 to be away from the first air outlet 200 when the thermal memory metal contracts. It should be noted that the selection of the thermal memory metal may be performed in combination with the corresponding phase transition temperature, so as to ensure that when the notebook computer is in a general working state, the heat generated by the working of the notebook computer is not enough to cause the thermal memory metal to contract, and only after the temperature is too high or the notebook computer is in a high power consumption state for a certain time, the heat generated by the working of the notebook computer can cause the thermal memory metal to contract, thereby achieving an effect that the heat dissipation structure is automatically opened according to the environmental temperature, when the environmental temperature is reduced below a first threshold value, the thermal memory metal can be slowly restored to a pre-contraction form, the corresponding stretching force can be slowly greater than the contraction force, and the air blocking door 60 approaches the first air outlet 200 under the stretching force until the first air outlet 200 is blocked.
If the current contraction structure 62 is an electromagnetic contraction device, the current contraction structure can be actively controlled by a notebook computer, when the heat dissipation function needs to be realized, the contraction structure 62 can be controlled to continuously increase the contraction force, and after the contraction force is greater than the extension force, the contraction structure 62 drives the air blocking door 60 to be away from the position of the first air outlet 200, so that the first air outlet 200 is opened; specifically, the notebook computer may have different powers when processing different tasks, or the notebook computer may also correspondingly open different working modes according to the user's usage requirements, and correspond to different powers in different working modes, and the higher the power is, the more obvious the heating effect of the notebook computer is, at this time, it may be set that when the power of the notebook computer exceeds the second threshold, the electromagnetic contraction device is started and starts to contract, when the contraction force is greater than the extension force, the electromagnetic contraction device drives the air blocking door 60 away from the position of the first air outlet 200, and the first air outlet 200 is opened, and when the power of the notebook computer is reduced below the second threshold, the electromagnetic contraction device may be automatically closed or the electromagnetic contraction device may be controlled to return to the pre-contraction state, that is, the first air outlet 200 is closed.
It should be noted that the above-mentioned shrinking structure 62 can use the thermal memory metal and the electromagnetic shrinking device at the same time when it is set up, so that it can automatically radiate heat when the temperature is too high, and at the same time, the opening of the heat radiating structure can be realized under the control of the notebook computer.
This embodiment has realized the on-off control to heat radiation structure through setting up the air blocking door to through the setting of extension structure and constriction structure, correspond the automation of having realized the air blocking door and open and close, can be according to notebook computer's in-service use condition when in-service use, correspond the switching selection that carries out heat radiation structure, in order to reach better result of use.

s1, the form mode of the notebook computer is determined, and if the form mode of the notebook computer is the normal mode, the step S2 is executed, and if the form mode of the notebook computer is the tent mode or the tablet mode, the step S3 is executed.
The conventional notebook computer usually has at least one form mode, such as a normal mode (i.e. a form mode when the notebook computer is generally used), a tablet mode (i.e. a form mode in which a keyboard side is completely rotated to a screen side back side and functions similar to the tablet computer are realized by directly touching a screen), a tent mode (i.e. a form mode in which a keyboard side is rotated to a screen side back side to form a certain included angle with the screen side and is placed on a desktop), and the like. Therefore, the notebook computer can judge the current form mode through the built-in sensors (such as a gyroscope and an angular velocity sensor), and further select whether to start the heat dissipation structure according to different form modes.
S2, judging whether the notebook computer is placed on the desktop, if not, executing S3.
And S3, controlling the contraction structure to contract so as to open the first air outlet.
In the case that the form mode of the notebook computer is the tent mode or the tablet mode, the user may perform the handheld operation on the computer for a large number of times during the use of the notebook computer, and therefore, in the two form modes, the opening of the first air outlet is preferably controlled to cool the bottom surface of the notebook computer.
When the notebook computer is in a common mode, whether the notebook computer is placed on a flat desktop or other flat object surfaces can be further judged through the internal sensor of the notebook computer, when the notebook computer is placed on the desktop for use, the bottom surface of the notebook computer is directly contacted with the desktop, a user can not usually sense the bottom surface temperature in the use process, and the first air outlet is not required to be opened to cool the bottom surface; if the notebook computer is not placed on the desktop, the possibility that the user holds the notebook computer by hands or places the notebook computer on legs for use is high, the user can intuitively feel the temperature of the bottom of the notebook computer at the moment, and the contraction structure can be controlled to contract to open the first air outlet, so that the bottom surface of the notebook computer is cooled.
In actual use, if a user actively sets the power consumption mode of the notebook computer, the power consumption mode of the notebook computer can be controlled by combining with the current power consumption mode when controlling the opening of the first air outlet, under a normal condition, the power consumption mode of the notebook computer is divided into a high power consumption mode, a low power consumption mode and a quiet mode, each hardware of the notebook computer continuously runs in an optimal state under the high power consumption mode, at the moment, the power consumption is increased, the corresponding heating problem is serious, under the low power consumption mode or the quiet mode, each hardware can be in a standby state or a dormant state when the notebook computer is in an inactive state until a new task is wakened up, at the moment, the power consumption is relatively low, and the heating problem is slight.
Specifically, when the notebook computer is in a normal mode and is not placed on a desktop, the current power consumption mode of the notebook computer can be further judged, and if the current power consumption mode of the notebook computer is in a high power consumption mode, the contraction structure is controlled to contract so as to open the first air outlet, so that the bottom surface of the notebook computer is cooled; if the current power consumption mode of the notebook computer is a low power consumption mode or a quiet mode, the power consumption of the notebook computer is low at the moment, even if the heating phenomenon exists, the user experience cannot be influenced, the first air outlet does not need to be opened, and if the power consumption mode is actively switched by a user in the subsequent use process or the current power of the notebook computer exceeds a second threshold value, the first air outlet is correspondingly opened.
It should be noted that, in the heat dissipation structure used in this embodiment, the contraction structure at least includes the electromagnetic contraction device, so as to ensure that the contraction structure can realize the contraction operation based on the control of the notebook computer, and of course, the contraction device may also include the thermal memory metal, so that on the basis that the contraction device can be controlled by the computer, when the ambient temperature exceeds the first threshold value, the contraction device automatically contracts to open the first air outlet, thereby achieving the cooling effect.
