The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, a heat dissipation system provided in an embodiment of the present invention is configured to be mounted on an electronic device to dissipate heat of a heating element of the electronic device, and mainly includes an air inlet, an air inlet channel, a fan, an air outlet channel, an air outlet, and an opening and closing mechanism 1. Wherein, the air outlet that communicates with the air-out passageway has a plurality ofly, and closing mechanism 1 then sets up at least on an air outlet to at least realize opening and closing of an air outlet. Therefore, when the user uses the electronic equipment provided with the heat dissipation system, the opening and closing mechanism 1 is controlled to act, the airflow carrying heat can be prevented from being sprayed out from the air outlet facing the user, the user can not be swept by the airflow at high temperature (relative to the room temperature), and the use experience of the user is improved.

Specifically, the opening/closing mechanism 1 of the present embodiment preferably includes: the baffles 11 are rotatably arranged on the air outlet, and a plurality of baffles 11 are arranged in parallel; and the connecting piece 12 is connected with all the baffles 11 and can drive all the baffles 11 to synchronously rotate, as shown in figures 1 and 2. That is, the opening and closing mechanism 1 has a structure similar to that of a louver, and the opening and closing of the outlet can be realized by the forward and reverse rotation of the shutter 11. This structure is adopted because each baffle 11 has a small area and requires a small rotation space, so that the opening and closing mechanism 1 provided in this embodiment can be better adapted to an electronic device having a small installation space. Certainly, on the premise that the normal opening and closing of the air outlet are met, the baffle 11 can be set to be one with a larger area, and the baffle 11 with the larger area can also realize the opening and closing of the air outlet through sliding.

Based on the above heat dissipation system, the embodiment further provides an electronic device, which has the above heat dissipation system. Specifically, the electronic device may be a notebook computer, a projector, or the like, and in this embodiment, the electronic device is preferably a notebook computer.

In order to further optimize the technical solution, in the electronic device provided in this embodiment, the air outlets are respectively disposed on the left end face 31, the right end face 32, and the rear end face 33 of the electronic device main body portion 3. When the electronic device is a notebook computer, it includes a main body portion 3 (i.e. a portion provided with a keyboard and a CPU), a screen portion 2 provided with a screen, and a rotating shaft mechanism (a main body component of the rotating shaft mechanism is a rotating shaft) rotatably connecting the main body portion 3 and the screen portion 2, and the left side end face 31 and the right side end face 32 refer to two opposite end faces perpendicular to the rotating shaft on the main body portion 3, and the rear side end face 33 refers to an end face on the main body portion 3 close to the screen portion 2 and parallel to the rotating shaft. And air outlets are formed in the left end face 31, the right end face 32 and the rear end face 33, so that the heat dissipation effect can be further improved, and the working performance of the notebook computer can be improved.

In addition to the above, it is also preferable that the opening and closing mechanism 1 is provided on each of the outlets on the left end surface 31, the right end surface 32, and the rear end surface 33, as shown in fig. 3 and 4. All set up closing mechanism 1 on every air outlet, can realize opening between the different air outlets and the switching of closed condition. For example, when the notebook computer is placed on a desktop and the screen portion 2 is turned over 0 ° to 180 ° with respect to the main portion 3, as shown in fig. 3, the opening/closing mechanism 1 can be operated to close the air outlets on the left end face 31 and/or the right end face 32 and open the air outlets on the rear end face 33, so that the high-temperature air can be ejected only from the rear end face 33 of the notebook computer, thereby preventing the hot air from being ejected from the air outlets on the left end face 31 and/or the right end face 32 and interfering with the use of the mouse by the user; when the screen part 2 of the notebook computer is turned over 180 ° to 300 ° relative to the main body part 3, a user will generally pick up the notebook computer when using the notebook computer, and will make the rear side end face 33 face itself, as shown in fig. 4, at this time, if a rear side air-out mode is also adopted, the face of the user will be purged, so when the screen part 2 is turned over to an angle range of 180 ° to 300 ° relative to the main body part 3, the opening and closing mechanism 1 can be controlled to turn the air outlets on the left side end face 31 and/or the right side end face 32 from a closed state to an open state, and the air outlets on the rear side end face 33 are turned from an open state to a closed state, so as to avoid the above-mentioned adverse conditions.

In addition, in this embodiment, it is also preferable that the air inlet of the heat dissipation system is formed in the bottom surface (the wall surface opposite to the keyboard) of the main portion 3, so that when the user turns the screen portion 2 to an angle of not less than 300 ° with respect to the main portion 3, the bottom surface of the main portion 3 does not adhere to the desktop when the notebook computer is used, regardless of whether the notebook computer is held in a hand or placed on the desktop, thereby achieving sufficient air inlet and further improving the heat dissipation effect of the notebook computer.

Specifically, the air outlet channel is preferably a channel surrounded by a housing of the electronic device, and the air inlet and the air outlet are openings formed in the housing. The arrangement mode can simplify the structure of the notebook computer, and the notebook computer is lighter, thinner and smaller. In addition, on the premise of not considering the factors, a special air inlet channel and a special air outlet channel can be arranged for the fan in the shell.

In this embodiment, it is further preferable that the opening and closing mechanism 1 is driven by a rotating shaft mechanism of the electronic device to move, so as to open and close the air outlet. In this embodiment, since the torsion member of the rotating shaft mechanism moves along the axial direction of the rotating shaft when the screen portion 2 is turned over relative to the main portion 3, the torsion member and the connecting member 12 are connected by the connecting rod 4, so that the baffle 11 can be driven to rotate in the process of turning over and closing the screen portion 2, and the switching of the air outlet can be realized. Specifically, when the notebook computer is closed, the air outlet on the left end face 31 and/or the right end face 32 is closed, the air outlet on the rear end face 33 is opened, when the screen portion 2 is turned over within a range of 0 ° to 180 °, the torsion member does not drive the baffle plate 11 to rotate, the air outlet on the left end face 31 and/or the right end face 32 is kept closed, the air outlet on the rear end face 33 is kept opened, when the screen portion 2 is turned over to 180 °, the torsion member drives the baffle plate 11 to rotate, so that the air outlet on the left end face 31 and/or the right end face 32 is switched from the closed state to the open state, and the air outlet on the rear end face 33 is switched from the open state to the closed state at the same time, so that the hot air is ejected from the rear side and is switched to the left side and. In addition, the movement of the opening and closing mechanism 1 can be realized by other methods, for example, a motor for driving the baffle plate 11 to rotate is additionally arranged in a notebook computer, and the motor is operated under the control of a CPU.

As shown in fig. 3 and 4, it is preferable that the air outlet includes a first air outlet 5 disposed on the left end surface 31, a second air outlet 6 disposed on the right end surface 32, and a third air outlet 7 and a fourth air outlet 8 disposed on the rear end surface 33, the air outlet channel preferably includes a first air outlet channel and a second air outlet channel, the heat dissipation system preferably includes a first fan and a second fan, and the first fan communicates with the first air outlet 5 and the third air outlet 7 through the first air outlet channel, and the second fan communicates with the second air outlet 6 and the fourth air outlet 8 through the second air outlet channel. By the arrangement, the air flow has pertinence, and the heat dissipation performance and the working effect of the notebook computer are further improved, so that the notebook computer is taken as a preferred arrangement mode of the embodiment.
