Description

Technical Field

[0002] With the continuous development of electronic devices, the heat dissipation problem of electronic devices such as mobile phones, tablets, and game consoles has always maintained a high level of attention. Among them, the greater the power of the heating element of the electronic device, the higher the temperature it emits, which will lead to poor thermal reliability of the heating element.

[0003] As a heat sink, the heat spreader is light and thin. At the same time, due to its divergent steam path and good 2D surface thermal conductivity, its heat dissipation effect is better than that of the fin-type heat sink. Applying it to electronic equipment can avoid performance loss caused by poor product heat dissipation.

[0004] In the related art, electronic devices generally have a sound-generating device that vibrates and generates sound, and a heat spreader fixed to the housing of the electronic device, which dissipates the heat generated by the working heating element through the heat spreader.

[0005] The heat spreader mainly includes a shell attached to the outer shell of the electronic device, a capillary core formed in the shell, and a liquid working medium arranged in the capillary core. When the electronic device is working, the VC heat spreader inside it can only passively reflux by gravity and capillary action after the water vapor condenses, which can easily lead to untimely reflux, causing "uniform temperature rise" inside the electronic device after long-term high-load operation, thus making the convection completely ineffective, and ultimately resulting in poor heat dissipation effect of the electronic device.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] The embodiment of the present invention provides a heat dissipation module 100, combined with Figures 1 to 6 As shown, it includes a sound-generating device 1 and a heat spreader 2 connected to the sound-generating device 1; the sound-generating device 1 includes a basin frame 11, a vibration system 12 fixed to the basin frame 11, and a magnetic circuit system 13 that drives the vibration system 12 to vibrate and generate sound.

[0036] The heat spreader 2 includes a main body 21 with an inner cavity, a capillary core (not shown) accommodated in the inner cavity, an opening 22 opened on the side of the main body 21 close to the sound-generating device 1 and connected to the inner cavity, and heat dissipation liquid accommodated in the inner cavity; the capillary core is arranged around the inner cavity and forms a ring loop, and the opening 22 cuts off the capillary core, so that the capillary core forms two breaks in its loop.

[0037] The vibration system 12 includes a diaphragm 121 fixed to the basin frame 11 and a voice coil 122 for driving the diaphragm 121 to vibrate.

[0038] The diaphragm 121 includes a vibration portion 1211, a first folded ring portion 1212 formed by bending and extending the outer periphery of the vibration portion 1211, and a second folded ring portion 1213 which is annular and has an inner periphery fixed to the outer periphery of the first folded ring portion 1212, and the outer periphery of the second folded ring portion 1213 is fixed to the basin frame 11; the voice coil 122 is fixed to the outer periphery of the first folded ring portion 1212.

[0039] The vibration system 12 further includes a frame 123 and an elastic member 124 .

[0040] The skeleton 123 includes a ring-shaped connecting portion 1231 and an extending portion 1232 formed by bending and extending the two opposite outer sides of the connecting portion 1231 toward the direction close to the magnetic circuit system 13. The inner periphery of the connecting portion 1231 is fixed between the outer periphery of the first folding ring portion 1212 and the voice coil 122, and the outer periphery of the connecting portion 1231 is fixed to the inner periphery of the second folding ring portion 1213.

[0041] The elastic member 124 includes two extension portions 1232 respectively fixed to the frame 123, each elastic member 124 includes a first fixed arm 1241 fixed to the side of the basin frame 11 away from the diaphragm 121, a second fixed arm 1242 fixed to the corresponding extension portion 1232, and two elastic arms 1243 formed by bending and extending the first fixed arm 1241 to the two ends of the second fixed arm 1242, the two elastic arms 1243 are respectively fixedly connected to the second fixed arm 1242, and the second fixed arm 1242 of one of the elastic members 124 is electrically connected to the voice coil 122 through the conductive member 1244.

[0042] The magnetic circuit system 13 includes a lower clamping plate 131 fixed to the basin frame 11, a main magnet 132 stacked and fixed on the lower clamping plate 131 close to the vibration system 12, and an auxiliary magnet 133 stacked and fixed on the lower clamping plate 131 and arranged around the main magnet 132, the auxiliary magnet 133 and the main magnet 132 are spaced to form a magnetic gap 10; the voice coil 122 is inserted and suspended in the magnetic gap 10.

[0043] In this embodiment, the auxiliary magnetic steels 133 include four and are respectively arranged on the four sides of the main magnetic steel 132, and the four auxiliary magnetic steels 133 are arranged in abutment with each other in sequence. Of course, according to actual needs, the auxiliary magnetic steels 133 can also be designed to be ring-shaped, or arranged to correspond to two opposite sides of the main magnetic steel 132, etc.

[0044] The magnetic circuit system 13 also includes an upper clamping plate 134 stacked and fixed on the side of the main magnetic steel 132 away from the lower clamping plate 131, a first center magnetic steel 135 stacked and fixed on the side of the upper clamping plate 134 away from the main magnetic steel 132, a second center magnetic steel 136 stacked and fixed on the side of the first center magnetic steel 135 away from the upper clamping plate 134, and a side clamping plate 137 stacked and fixed on the side of the auxiliary magnetic steel 133 away from the lower clamping plate 131, and the second center magnetic steel 136 is spaced apart from the vibration part 1211.

[0045] Specifically, the heat dissipation module 100 also includes a ring-shaped and elastic support member 3, the outer periphery of the support member 3 is attached and fixed to the side of the main body 21 close to the sound-generating device 1, and the inner periphery of the support member 3 is fixed to the magnetic circuit system 13. The support member 3 and the magnetic circuit system 13 jointly cover the opening 22 to close the inner cavity. This design can transmit the vibration generated by the vibration system 12 to the magnetic circuit system 13 through the elastic action of the support member 3, so that the heat spreader 2 can use the vibration of the magnetic circuit system 13 to push the heat dissipation liquid inside it to achieve the effect of active heat dissipation.

[0046] The support member 3 includes a ring-shaped support portion 31 whose outer periphery is attached to the main body 21 and a first elastic connector 32 fixed to the inner periphery of the support portion 31 . The inner periphery of the first elastic connector 32 is attached to the magnetic circuit system 13 .

[0047] The opposite sides of the support part 31 are respectively provided with fixing parts 33 protruding and extending in the direction of the sound generating device 1, and each fixing part 33 extends to the basin frame 11 and forms a fixed connection with the basin frame 11; the support member 31 also includes two elastic second elastic connecting members 34, and each second elastic connecting member 34 is respectively clamped and fixed between the corresponding fixing part 33 and the magnetic circuit system 13. This design can improve the elastic connection effect between the support member 3 and the magnetic circuit system 13.

[0048] In this embodiment, the inner periphery of the first elastic connector 32 is attached and fixed to the side of the lower clamp 131 away from the vibration system 12. At this time, the support portion 31, the first elastic connector 32 and the lower clamp 131 jointly cover the opening portion 22 to close the inner cavity; each second elastic connector 34 is respectively clamped between a corresponding fixing portion 33 and a secondary magnet 133.

[0049] The main body 21 includes a bottom plate 211 fixed to the support member 3 and in an annular shape, a first bending portion 212 formed by bending and extending the outer periphery of the bottom plate 211, a second bending portion 213 formed by bending and extending the inner periphery of the bottom plate 211, and a top plate 214 bent and extended from the first bending portion 212 away from the bottom plate 211 and connected to the second bending portion 213. The bottom plate 211, the first bending portion 212, the second bending portion 213 and the top plate 214 are jointly arranged to form an inner cavity; the opening 22 is a notch of the bottom plate 211, and the capillary core forms a loop along the space between the bottom plate 211 and the top plate 214. Of course, the structure of the main body 21 is not limited to this description, and its structure can be designed according to the layout of the heating element of the electronic device.

[0050] In this embodiment, the outer periphery of the support portion 31 is attached and fixed to a side of the bottom plate 211 close to the sound-generating device 1 .

[0051] The heat spreader 2 also includes a first one-way valve 23 and a second one-way valve 24, which are respectively arranged in the inner cavity. The flow direction of the first one-way valve 23 is the same as that of the second one-way valve 24. The first one-way valve 23 and the second one-way valve 24 are respectively arranged on opposite sides of the opening 22 to block the two breaks; the first one-way valve 23 and the second one-way valve 24 are both arranged between the bottom plate 211 and the top plate 214. This design allows the heat dissipation liquid to circulate in the direction of the first one-way valve 23, the magnetic circuit system 13 and the second one-way valve 24 in sequence, so that the heat dissipation liquid can take out the heat emitted by the sound device 1 during the circulation process, and actively dissipate heat through the vibration of the magnetic circuit system 13, so as to improve the heat dissipation effect of the heat dissipation module 100. Of course, the heat dissipation liquid can also circulate in the direction of the second one-way valve 24, the magnetic circuit system 13 and the first one-way valve 23, and its function is the same as the above function, which will not be repeated here.

[0052] The support member 3 is attached and fixed to the side of the main body 21 close to the sound-generating device 1 through the fixing member 4; that is, the fixing member 4 is attached and fixed between the support member 31 and the bottom plate 211, which is equivalent to the support member 3 being indirectly fixed to the main body 21 through the fixing member 4. Since the direct fixing of the support member 3 and the main body 21 will lead to poor stability, adding the fixing member 4 between the support member 3 and the main body 21 can improve the fixing effect between the support member 3 and the main body 21.

[0053] Of course, the heat spreader 2 can be used with a single core or in combination with a BOX device; that is, the heat spreader 2 can be used alone with a sound-generating device, or in combination with speaker boxes, mobile phones, tablets, game consoles and other electronic devices with vibration and sound-generating functions.

[0054] Compared with the related art, the heat dissipation module 100 in this embodiment connects the main body 21 of the heat spreader 2 and the magnetic circuit system 13 through an elastic support member 3, and the support member 3 and the magnetic circuit system 13 jointly cover the opening 22 of the heat spreader 2 to seal the inner cavity of the heat spreader 2. In this way, when the heat dissipation module 100 is working, the vibration system 12 will vibrate and make a sound and transmit the vibration to the magnetic circuit system 13 through the elastic action of the support member 3, so that the heat spreader 2 can use the vibration of the magnetic circuit system 13 to push the heat dissipation liquid inside it to achieve the effect of active heat dissipation, thereby improving the heat dissipation effect of the heat dissipation module 100. At the same time, the heat dissipation module 100 in this embodiment only needs to extend the original heat spreader 2 in the electronic device to the position of the sound-generating device 1, so that the overall layout of the electronic device can be effectively utilized without increasing the installation space.

[0055] Embodiment 2

[0056] Combination Figures 7 to 9 As shown, the heat dissipation module 100 in the embodiment of the present invention further includes a heat insulation film 5 attached and fixed to a side of the magnetic circuit system 13 away from the vibration system 12 .

[0057] In this embodiment, the heat-insulating membrane 5 is attached and fixed to the side of the lower clamping plate 131 away from the vibration system 12. This design can prevent the working heat of the sound-generating device 1 from causing the temperature of the heat-generating plate 2 to rise. The heat-insulating membrane 5 is determined based on the working heat of the sound-generating device 1.

[0058] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
