[0025] The heat dissipation performance plays a crucial role in ensuring the performance, stability and life of electronic products, and the active heat dissipation mode with better heat dissipation performance is difficult to be arranged across the folding area due to the folding of the electronic product, thereby leading to poor heat dissipation performance of the overall electronic product.

[0026] The embodiments of the present application propose a heat dissipation system and a foldable electronic product, which are designed to at least solve the problem of poor heat dissipation performance caused by the difficulty of applying the active heat dissipation mode of the folding electronic product in the related art.

[0027] Please refer to FIG. 1, FIG. 2 and FIG. 3, in the embodiments of the present application, the heat dissipation system 100 is applied to the foldable electronic product 1000, the heat dissipation system 100 includes a plurality of heat dissipation channels 1, at least two of the plurality of heat dissipation channels 1 are relatively movable and are arranged in two folding bodies 200 of the foldable electronic product 1000, so as to move with the two folding bodies 200, so that the plurality of heat dissipation channels 1 have a docking position and a separated position; in the docking position, the plurality of heat dissipation channels 1 are docked; in the separated position, at least part of the heat dissipation channels 1 are disconnected.

[0028] In the technical scheme of the embodiment of the present application, at least two of the plurality of heat dissipation channels 1 are relatively movably arranged and separately arranged on the two folding bodies 200 of the foldable electronic product 1000 to move with the two folding bodies 200; when the two folding bodies 200 are unfolded or folded, the plurality of heat dissipation channels 1 are moved, the plurality of heat dissipation channels 1 can be connected to form a complete communication channel, so that the heat dissipation medium can flow from one of the folding bodies 200 to the other folding body 200, and at least part of the plurality of heat dissipation channels 1 can be disconnected to adapt to the folding of the two folding bodies 200; in this way, the active heat dissipation mode can be applied in the foldable electronic product 1000, and the heat dissipation effect is guaranteed, and unlike the hose directly connected to the two folding bodies 200, the hose will not be broken with the repeated folding of the two folding bodies 200.

[0029] For the foldable electronic product 1000, a hinge structure 2 is usually arranged between the two folding bodies 200, and the two folding bodies 200 have a certain distance, so at least part of the heat dissipation channels 1 are located in the area where the hinge structure 2 is located, in some embodiments, the heat dissipation channel 1 corresponding to the folding body 200 can directly extend to the folding area where the hinge structure 2 is located; in some embodiments, please refer to FIG. 8 and FIG. 9, the heat dissipation system 100 further comprises a hinge structure 2 connected between the two folding bodies 200, and at least part of the heat dissipation channels 1 are arranged on the hinge structure 2 to move with the hinge structure 2; in this way, compared with the heat dissipation channel 1 corresponding to the folding body 200 directly extending to the area where the hinge structure 2 is located, part of the heat dissipation channels 1 have a connection relationship with the hinge structure 2, so that the heat dissipation channels 1 can be used as reinforcing members of the hinge structure 2, and the hinge structure 2 can stably support the heat dissipation channels 1.

[0030] In order to adapt to the folding and unfolding of the two folding bodies 200, generally at least part or the whole of the heat dissipation channels 1 is located in the folding area where the hinge structure 2 is located. In some embodiments, the plurality of heat dissipation channels 1 includes a plurality of first heat dissipation channels 11 and two second heat dissipation channels 12, which are correspondingly arranged on the two folding bodies 200. The hinge structure 2 includes a connecting seat 21 and two hinge arms 22 rotatably connected to the two ends of the connecting seat 21, and the two hinge arms 22 are respectively connected to the two folding bodies 200. In each of the first heat dissipation channels 11, at least two of them are arranged on the two hinge arms 22 to move with the two hinge arms 22. In this way, when the two folding bodies 200 are folded or unfolded, the two hinge arms 22 will move, and the two first heat dissipation channels 11 will follow and be connected or disconnected. The structure is simple and stable, and by arranging the second heat dissipation channels 11 on the hinge arms 22, it is not necessary to extend the second heat dissipation channels 12 corresponding to the folding bodies 200 to the folding area, that is, it is not necessary to protrude the second heat dissipation channels 12 from the folding bodies 200, which is more convenient for transportation and assembly.

[0031] The number of first heat dissipation channels 11 arranged on each hinge arm 22 is not limited to one, but can also be multiple. For example, the hinge arm 22 itself may have structural changes during folding and unfolding. In order to reduce the possibility of damage to the first heat dissipation channels 11 due to structural changes of the hinge arm 22, multiple first heat dissipation channels 11 can be arranged on the hinge arm 22 to adapt to the structural changes of the hinge arm 22 itself. Therefore, the number of first heat dissipation channels 11 on the hinge arm 22 can be adjusted freely according to different forms, as long as multiple first heat dissipation channels 11 can be connected at the connection position.

[0032] The second heat dissipation channels 12 and the adjacent first heat dissipation channels 11 can be relatively movable or fixed. When the hinge arm 22 and the folding body 200 are in a fixed relationship, the hinge structure 2 can be installed with the folding body 200, and then the first heat dissipation channels 11 and the corresponding second heat dissipation channels 12 can be fixed by welding or bonding. When the hinge arm 22 and the folding body 200 are rotatably connected, the second heat dissipation channels 12 and the adjacent first heat dissipation channels 11 have a relative rotation relationship. As long as the second heat dissipation channels 12 and the first heat dissipation channels 11 can be connected at the connection position, the specific form between the second heat dissipation channels 12 and the adjacent first heat dissipation channels 11 can be adjusted according to the connection relationship between the hinge arm 22 and the folding body 200.

[0033] When two first heat dissipation channels 11 are arranged on two hinged arms 22, in order to enable the two first heat dissipation channels 11 to be connected at one end away from the corresponding second heat dissipation channel 12, it is necessary to arrange the two first heat dissipation channels 11 to be longer and to extend as much as possible in the direction of the connecting seat 21, or the spacing between the two hinged arms 22 is small enough; when the first heat dissipation channels 11 are arranged to be longer, while ensuring the size of the overall hinge structure 2, please refer to FIG. 8 and FIG. 9, in the process of rotation, the first heat dissipation channels 11 are easy to collide with other components, which affects the use; when the spacing between the two hinged arms 22 is small enough, there is no space between them, and for the foldable electronic product 1000, such as a folding mobile phone, the display screen after folding usually needs to be accommodated between the two hinged arms 22, which will result in no space to accommodate the display screen. Therefore, in some embodiments, at least one of the first heat dissipation channels 11 is arranged on the connecting seat 21; in this way, by arranging the first heat dissipation channels 11 on the connecting seat 21 to connect the first heat dissipation channels 11 on the two hinged arms 22, it is not necessary to arrange the first heat dissipation channels 11 on the hinged arms 22 to be very long, nor is it necessary to arrange the spacing between the two hinged arms 22 to be very small, and it is also possible to enable the first heat dissipation channels 11 on the two hinged arms 22 to be connected.

[0034] The design does not limit the specific number of the first heat dissipation channels 11 on the connecting seat 21, for example, the connecting seat 21 itself will follow the folding or relative movement during the unfolding or folding process of the foldable electronic product 1000, then multiple first heat dissipation channels 11 need to be arranged on the connecting seat 21 to adapt to the movement of the connecting seat 21 itself, that is, for different structural forms of the connecting seat 21 of the hinge structure 2, the arrangement of the first heat dissipation channels 11 on the connecting seat 21 can be flexibly adjusted.

[0035] As known from the above, the number of the first heat dissipation channels 11 can be zero (the second heat dissipation channel 12 directly extends to the folding area), two, three or even more, in some embodiments, please refer to FIG. 2 and FIG. 3, the number of the first heat dissipation channels 11 is set to three; in some embodiments, please refer to FIG. 4 and FIG. 5, the number of the first heat dissipation channels 11 is set to six; as long as the multiple first heat dissipation channels 11 can be connected to form a channel connecting the two second heat dissipation channels 12 during the movement of following the two folding bodies 200.

[0036] There are various relative movement modes between the first heat dissipation channels 11. In some embodiments, the first heat dissipation channels 11 can be relatively rotated (for example, as shown in FIG. 6a), or relatively slid (for example, as shown in FIGS. 6b and 6c). When the first heat dissipation channels 11 need to be relatively slid, the relative rotation of the two folding bodies 200 needs to be changed into sliding through a connecting rod structure. Of course, a combination of relative rotation and relative sliding can also be used. The specific movement mode between the first heat dissipation channels 11 can be selected according to actual conditions.

[0037] For the folding mobile phone and other foldable electronic products 1000 with flexible screens such as folding display screens, when folded, the flexible screen will generally bend towards the two hinge arms 22 of the hinge structure 2. In order to accommodate the flexible screen and prevent the flexible screen from being damaged due to extrusion, in some embodiments, please refer to FIG. 8, in the separated position, the two hinge arms 22 are at least partially separated to form an accommodation space. In this way, the bent flexible screen can be accommodated through the accommodation space. In some embodiments, the two hinge arms 22 can be partially separated or fully separated.

[0038] In some embodiments, in order to improve the sealing performance when the two heat dissipation channels 1 are docked, please refer to FIGS. 6a-6c, in at least two adjacent heat dissipation channels 1, the end of one of the heat dissipation channels 1 is provided with an elastic sealing part 3, so that in the docked position, the two heat dissipation channels 1 are sealed and docked through the elastic sealing part 3. In this way, by extruding the elastic sealing part 3 when the two heat dissipation channels 1 are docked, the elastic sealing part 3 is in a compressed state, thereby improving the sealing performance of the docking and ensuring the smooth flow of the heat dissipation medium in each heat dissipation channel 1.

[0039] In some embodiments, the fixing mode of the elastic sealing part 3 and the heat dissipation channel 1 can be adhesion, injection molding, screw fixation or other fixing modes. Of course, the elastic sealing part 3 and the heat dissipation channel 1 can be integrally provided, that is, at least the end of the heat dissipation channel 1 is made of elastic material to form the elastic sealing part 3.

[0040] The embodiments of the present application do not limit the specific material of the elastic sealing part 3. The elastic sealing part 3 can be a porous sealing material such as foam, a high-elasticity soft pad material such as silica gel, or other soft materials. In some embodiments, please refer to FIG. 7, the elastic sealing part 3 can also be a corrugated elastic structure made of semi-hard or even hard material.

[0041] The abutment of the elastic sealing part 3 and the abutment surface of the other heat dissipation channel 1 affects the sealing performance and service life. For example, as shown in FIG. 6b, in order to ensure the sealing between the heat dissipation channels 1, the elastic sealing part 3 needs to be pressed on all sides. Therefore, in some embodiments, the elastic sealing part 3 and the corresponding heat dissipation channel 1 have a matching surface at the abutment position, and the matching surface intersects the movement direction between the elastic sealing part 3 and the corresponding heat dissipation channel 1. In this way, when the abutment is completed, the elastic sealing part 3 can be in a state of being pressed on all sides, thereby reducing the possibility of leakage of the heat dissipation medium.

[0042] When the relative movement of the two heat dissipation channels 1 is linear movement, if the matching surface is an inclined surface, the elastic sealing part 3 will be unevenly pressed on the matching surface, that is, some positions are pressed more and some positions are pressed less. Long-term use will cause the elastic sealing part 3 to be more prone to failure, affecting the sealing performance. Therefore, in some embodiments, as shown in FIGS. 6a-6c (the arrow direction in the figure is the relative movement direction of the two heat dissipation channels 1), the matching surface is perpendicular to the movement direction between the elastic sealing part 3 and the corresponding heat dissipation channel 1. In this way, when the two heat dissipation channels 1 are abutted, at the moment when the heat dissipation channel 1 and the elastic sealing part 3 are abutted, the elastic sealing part 3 can be pressed on all sides, and the pressure is balanced, thereby ensuring the sealing between the heat dissipation channels 1 and improving the service life of the elastic sealing part 3.

[0043] In some embodiments, the elastic sealing part 3 can be arranged on both adjacent heat dissipation channels 1. In this way, the two elastic sealing parts 3 have the matching surface at the abutment position.

[0044] In some embodiments, in order to improve the reliability of the abutment between the heat dissipation channels 1, as shown in FIG. 10, a positioning structure 4 is arranged between the two adjacent heat dissipation channels 1. The positioning structure 4 includes a positioning part 41 and a positioning matching part 42 arranged on the two heat dissipation channels 1, respectively. The positioning part 41 and the positioning matching part 42 can cooperate at the abutment position to position the two heat dissipation channels 1. In this way, the positioning part 41 and the positioning matching part 42 can assist the abutment of the two heat dissipation channels 1, thereby improving the stability of the abutment.

[0045] The forms of the positioning part 41 and the positioning matching part 42 are various, in some embodiments, one of the positioning part 41 and the positioning matching part 42 is provided as a convex part, and the other is provided as a concave part; in some embodiments, the positioning part 41 and the positioning matching part 42 can also be positioned in a magnetic attraction manner, etc.; in some embodiments, the positioning part 41 and the positioning matching part 42 can be provided as a toothed structure.

[0046] In some embodiments, one end of the heat dissipation channel 1 can be provided with the elastic sealing part 3 and one of the positioning part 41 and the positioning matching part 42, in order to make the functions of the elastic sealing part 3 and the positioning structure 4 not affect each other, the elastic sealing part 3 can be provided on the end surface of the heat dissipation channel 1, and the positioning part 41 or the positioning matching part 42 is provided on the outer circumferential side of the end of the heat dissipation channel 1; or both can be provided on the end surface of the heat dissipation channel 1, at this time, the elastic sealing part 3 cannot completely cover the heat dissipation channel 1, and is provided to occupy a part of the end surface, in this way, the positioning part 41 or the positioning matching part 42 can be provided on the end surface of the heat dissipation channel 1 and located on the outer side or the inner side of the elastic sealing part 3.

[0047] In some embodiments, in order to enable the heat dissipation medium to flow between the two second heat dissipation channels 12 in the docking position, thereby achieving active heat dissipation, the heat dissipation system 100 further comprises a driving device 5, which is used to drive the heat dissipation medium in each heat dissipation channel 1 to flow in the docking position.

[0048] The specific form of the driving device 5 is various, in some embodiments, the driving device 5 comprises a fan provided in one heat dissipation channel 1; in some embodiments, the driving device 5 can also be a blower or a micro air pump, etc.

[0049] The driving device 5 is not necessarily provided, and can be driven by the driving device 5 of the electronic product itself or the driving device 5 of the external environment.

[0050] The heat dissipation medium is a medium for flowing in each heat dissipation channel 1 to take away the heat of the two folding bodies, in some embodiments, the heat dissipation medium can be air, and the two heat dissipation channels 1 on the two folding bodies 200 are directly communicated with the external air, which is low in cost; in some embodiments, the heat dissipation medium can be a rare gas such as helium, etc. with better heat conduction performance than air, by providing a detachable external pipe, in the docking position, the two ends of the external pipe are connected with the two heat dissipation channels 1 on the two folding bodies 200 respectively, and helium or the like is filled in the external pipe as the heat dissipation medium.

[0051] With the use of time, inevitably, there will be leakage and clogging between each of the heat dissipation channels 1, in order to detect leakage and clogging, in some embodiments, the heat dissipation system 100 also includes a detection device for detecting the flow parameters of the heat dissipation medium in each of the heat dissipation channels 1, and the flow parameters are used to determine whether there is leakage and clogging.

[0052] The detection device has various forms, in some embodiments, the detection device can be a wind pressure sensor, which detects the wind pressure to determine whether there is leakage and clogging, the detection device can be a flow sensor and a wind volume sensor.

[0053] The specific setting position of the detection device is determined according to the flow direction of the heat dissipation medium, among the two heat dissipation channels 1 corresponding to the two folding bodies 200, one is the air inlet end, and the other is the air outlet end, the detection device is arranged in the heat dissipation channel 1 as the air outlet end, and the parameters detected by the detection device are compared with the preset parameters, that is, the leakage and clogging can be determined; of course, the detection device can also be arranged in both of the heat dissipation channels 1 corresponding to the two folding bodies 200.

[0054] In some embodiments, in order to improve the dustproof ability of each of the heat dissipation channels 1, please refer to figure 11, at least one of the heat dissipation channels 1 is provided with a dustproof device 6, the dustproof device 6 can be arranged in the first heat dissipation channel 11, or in the second heat dissipation channel 12.

[0055] When the dustproof device 6 is arranged on the first heat dissipation channel 11, although the dustproof ability of the overall structure can be improved, the external dust impurities may adhere to the second heat dissipation channel 12, thereby affecting the performance of the overall heat dissipation system 100; therefore, in some embodiments, the dustproof device 6 is arranged at the end of the second heat dissipation channel 12 away from the corresponding first heat dissipation channel 11, that is, it can reduce the possibility of dust impurities entering the second heat dissipation channel 12, while also reducing the possibility of dust impurities entering the first heat dissipation channel 11, and facilitating the maintenance and cleaning of the dustproof device 6.

[0056] The setting position of the dustproof device 6 is also determined according to the air inlet end and the air outlet end of the two second heat dissipation channels 12, the dustproof device 6 is arranged in the second heat dissipation channel 12 as the air inlet end, which can greatly reduce the possibility of external dust entering each of the heat dissipation channels 1; of course, the dustproof device 6 can also be arranged in both of the second heat dissipation channels 12.

[0057] The dustproof device 6 can have various specific forms. In some embodiments, the dustproof device 6 includes an electrostatic precipitator or a dustproof screen arranged at one end of the second heat dissipation channel 12 away from the first heat dissipation channel 11.

[0058] To further improve the protection performance of each heat dissipation channel 1, in some embodiments, a cover plate that can be opened and closed is arranged at the end of the heat dissipation channel 1 corresponding to the folding body 200. In this way, when the heat dissipation system 100 is not used, the heat dissipation channel 1 is blocked by the cover plate, further reducing the possibility of foreign matter entering.

[0059] The cover plate can be manually opened and closed or automatically opened and closed, and the embodiments of the present application do not limit this.
