[0035] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0036] Next, refer to Figures 1 - 8 , and describe the mobile phone heat dissipation device 100 according to the embodiments of the present utility model.

[0037] As Figure 1 , Figure 2 and Figure 3As shown in the figure, the mobile phone heat dissipation device 100 of the embodiment of the present utility model includes: a housing 10, a heat conducting sheet 20, a heat dissipation component 30, a battery 40, and a charging and discharging component 50. The housing 10 is provided with a mobile phone fixing groove 101 for wrapping the four corners of the mobile phone. The heat conducting sheet 20 is arranged on the bottom groove wall 101a of the mobile phone fixing groove 101 for attaching to the back of the mobile phone. The heat dissipation component 30 is arranged on the housing 10 and can perform heat exchange with the heat conducting sheet 20; the battery 40 is electrically connected to the heat dissipation component 30 and can supply power to the heat dissipation component 30; the charging and discharging component 50 is electrically connected to the battery 40 and can charge the battery 40 and the mobile phone.

[0038] In the above embodiment, by setting the mobile phone fixing groove 101, the housing 10 can also function as a mobile phone case and be sleeved on the mobile phone. "The mobile phone fixing groove 101 is used to wrap the four corners of the mobile phone" can be understood as that the mobile phone fixing groove 101 can be a sunken groove provided on the housing 10, that is, the mobile phone fixing groove 101 has four groove walls, which can better wrap around the mobile phone on all sides, have better wrapping performance for the mobile phone, and have more reliable cooperation with the mobile phone, reducing the probability of the mobile phone detaching from the housing 10 and playing a better protective role for the mobile phone. The mobile phone fixing groove 101 can also refer to a groove defined by multiple protruding structures on the housing 10. For example, four L-shaped protruding structures are provided at the four corners of the housing 10, which can also fix the four corners of the mobile phone and play the role of fixing and protecting the mobile phone. Of course, the above are only examples, and the setting method of the mobile phone fixing groove 101 is not limited to this and will not be elaborated here.

[0039] The heat conducting sheet 20 can refer to a sheet-like component that plays a role in conducting heat. The heat conducting sheet 20 can be made of a metal material with high thermal conductivity, which can be but is not limited to copper, aluminum, silver, etc. The heat conducting sheet 20 can also be made of a non-metallic material with good thermal conductivity, which can be but is not limited to graphite, ceramics, etc.

[0040] The heat dissipation component 30 can refer to a component that can play a role in heat dissipation. In this embodiment, the structure of the heat dissipation component 30 is not specifically limited. When the mobile phone is sleeved in the mobile phone fixing groove 101, since the heat conducting sheet 20 is arranged on the bottom groove wall 101a of the mobile phone fixing groove 101, the heat conducting sheet 20 can be attached to the back of the mobile phone, transferring the heat on the back of the mobile phone to the heat dissipation component 30. The heat dissipation component 30 can work to release the heat of the heat conducting sheet 20 in time, thereby realizing heat dissipation of the back of the mobile phone.

[0041] On the one hand, the battery 40 can play a role in powering the heat dissipation component 30, and on the other hand, it can charge or directly supply power to the mobile phone through the charging and discharging component 50, increasing the battery life of the mobile phone. In this embodiment, the charging and discharging component 50 can supply power to the mobile phone through a wire harness or through a wireless charging module, which is not specifically limited here. The structure of the charging and discharging component 50 can refer to related technologies and is not specifically limited here.

[0042] According to the mobile phone heat dissipation device 100 of the embodiments of the present utility model, the whole machine can have the function of a mobile phone case through the mobile phone fixing groove 101 of the housing 10, and the fixation with the mobile phone is more reliable. Moreover, after being combined with the mobile phone, it can effectively protect the mobile phone, avoiding damage to the mobile phone due to bumping or dropping. At the same time, the whole machine can also play a role in dissipating heat and cooling the mobile phone, reducing the probability of overheating of the mobile phone during use, which is beneficial to improving the performance of the mobile phone. Through the battery 40 and the charge and discharge component 50, the device can also supply power to the mobile phone, which can increase the battery life of the mobile phone and reduce the charging frequency of the mobile phone. It can be seen that the mobile phone heat dissipation device 100 can have multiple functions, which is beneficial to improving the user experience.

[0043] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the heat conducting sheet 20 includes a first heat conducting portion 21 and a second heat conducting portion 22. The first heat conducting portion 21 is used for fitting on the central area of the back of the mobile phone; the second heat conducting portion 22 is used for fitting on the area of the back of the mobile phone near the camera.

[0044] It can be understood that the heat generating positions of the mobile phone generally mainly concentrate in two positions. One is the position where the mobile phone battery is located, and the other is the position where the hardware (such as the chip) of the mobile phone is located. Since the distribution of each component inside the existing mobile phone has been fixed, the mobile phone battery is generally set at the central position of the back of the mobile phone, and the heat generating hardware is arranged around the camera on the back of the mobile phone. In the above embodiment, the first heat conducting portion 21 refers to the central position provided in the mobile phone fixing groove 101, which can dissipate heat from the central area of the back of the mobile phone, that is, dissipate heat from the position where the mobile phone battery is located. The second heat conducting portion 22 is arranged in the upper part area of the mobile phone fixing groove 101, and can dissipate heat from the position where the heat generating hardware on the back of the mobile phone is located.

[0045] That is to say, by setting the heat conducting sheet 20 to include the first heat conducting portion 21 and the second heat conducting portion 22, on the one hand, the heat conducting sheet 20 has a larger area and can cover a larger area of the back of the mobile phone, thereby effectively improving the heat dissipation efficiency. On the other hand, the first heat conducting portion 21 and the second heat conducting portion 22 can dissipate heat to the main heat dissipation positions of the mobile phone in a targeted manner, which can further improve the heat dissipation efficiency, thereby effectively reducing the temperature rise during the operation of the mobile phone and significantly improving the performance of the mobile phone.

[0046] Optionally, the second heat conducting portion 22 can be provided on one side of the first heat conducting portion 21 in the length direction of the housing 10. The length direction of the housing 10 can refer to Figure 1 and Figure 2In the up and down direction. That is to say, the main heat-generating hardware of the mobile phone can be set on one side of the mobile phone camera. Therefore, a second heat-conducting part 22 can be set on one side of the first heat-conducting part 21. For example, the second heat-conducting part 22 is arranged on the left or right side of the first heat-conducting part 21, and the first heat-conducting part 21 and the second heat-conducting part 22 are integrally L-shaped.

[0047] Optionally, the second heat-conducting part 22 can be arranged on both sides of the first heat-conducting part 21 in the length direction of the housing 10. Referring to the above, the main heat-generating hardware of the mobile phone can also be set on both sides of the mobile phone camera. Therefore, the second heat-conducting part 22 can be arranged on both sides of the first heat-conducting part 21. For example, the second heat-conducting part 22 is arranged on both the left and right sides of the first heat-conducting part 21, and the first heat-conducting part 21 and the second heat-conducting part 22 are integrally U-shaped.

[0048] Optionally, the second heat-conducting component 22 can also be rectangular and directly cover the position where the camera is located on the back of the mobile phone.

[0049] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the second heat-conducting part 22 is connected to the first heat-conducting part 21, and the second heat-conducting part 22 is provided with a camera avoidance hole 22a.

[0050] Since most mobile phone cameras are generally convexly arranged, by providing the camera avoidance hole 22a in the second heat-conducting part 22, the protruding camera can be avoided, so that the second heat-conducting part 22 can better fit around the mobile phone camera and make full contact with the back of the mobile phone for heat dissipation, thereby better dissipating heat from the surrounding position of the mobile phone camera.

[0051] Referring to the previous examples, when the second heat-conducting part 22 is two and is integrally U-shaped with the first heat-conducting part 21, a camera avoidance hole 22a is jointly formed between the two second heat-conducting parts 22 and the first heat-conducting part 21. When the second heat-conducting component 22 is rectangular, the camera avoidance hole 22a can be a hole directly opened on the second heat-conducting component 22 (see Figure 1 ).

[0052] Optionally, the camera avoidance hole 22a can be, but is not limited to, a round hole, a square hole, an oval hole, etc.

[0053] In some embodiments of the present invention, as Figure 1 shown, the housing 10 is provided with an opening 102 communicating with the bottom groove wall 101a. The heat dissipation assembly 30 includes a Peltier element 31, a heat sink 32 and a fan 33. The Peltier element 31 is arranged on the housing 10, and the cold end of the Peltier element 31 passes through the opening 102 and is attached to the first heat-conducting part 21. The Peltier element 31 is electrically connected to the battery 40; the heat sink 32 is attached to the hot end of the Peltier element 31; the fan 33 is arranged on the side of the heat sink 32 away from the Peltier element 31 and is electrically connected to the battery 40.

[0054] The thermoelectric cooler 31 may refer to a semiconductor refrigeration component. After being powered on by the battery 40, one side is the cold end, which can absorb heat and generate cold, and the other side is the hot end, which can release heat.

[0055] The heat sink 32 may refer to a device that can dissipate heat efficiently, generally in the shape of a plate, sheet or multi-sheet. Exemplarily, referring to Figure 1 and Figure 5 , the heat sink 32 may have a plurality of heat dissipation columns 321 arranged in an array. Through the plurality of heat dissipation columns 321, the heat dissipation area can be increased, thereby achieving a better heat dissipation effect.

[0056] In the above solution, when the heat dissipation component 30 works, the battery 40 can drive the thermoelectric cooler 31 and the fan 33 to work. The cold end of the thermoelectric cooler 31 can absorb heat and generate cold. Since the cold end of the thermoelectric cooler 31 is in close contact with the first heat conducting part 21, the heat conduction between the two is more sufficient. The thermoelectric cooler 31 can quickly exchange the heat on the back of the mobile phone through the first heat conducting part 21 and the second heat conducting part 22. The fan 33 can drive the air flow to quickly pass through the heat sink 32 and quickly take away the heat of the heat sink 32. Since the heat sink 32 can exchange heat with the hot end of the thermoelectric cooler 31, the heat of the hot end of the thermoelectric cooler 31 can be quickly taken away, so that the cold end of the thermoelectric cooler 31 can efficiently refrigerate, and then the heat dissipation of the back of the mobile phone can be realized.

[0057] It can be understood that by adopting the above heat dissipation component 30, since the thermoelectric cooler 31 can generate cold, a better heat dissipation and cooling effect can be brought, and the heat dissipation efficiency of the mobile phone can be improved.

[0058] In some embodiments of the present utility model, the periphery of the thermoelectric cooler 31 is wrapped with a heat insulation layer.

[0059] The heat insulation layer may refer to a heat insulation material arranged in a circle around the thermoelectric cooler 31. The material of the heat insulation layer can be an inorganic heat insulation material, such as but not limited to rock wool, glass wool, aluminum silicate fiber, etc. The material of the heat insulation layer can also be an organic heat insulation material, such as but not limited to polyurethane foam plastic, polyethylene foam plastic, etc. The material of the heat insulation layer can also be a composite heat insulation material, such as but not limited to aerogel, vacuum insulation panel, etc.

[0060] In the above technical solution, the heat insulation layer can play a heat insulation role on the periphery of the thermoelectric cooler 31, so that the cold generated by the cold end of the thermoelectric cooler 31 is not easily lost to the surroundings, and prevents the heat transferred from the outside on the housing 10 from exchanging heat with the cold end of the thermoelectric cooler 31, so that the cold of the cold end of the thermoelectric cooler 31 can fully exchange heat with the back of the mobile phone, and the heat dissipation efficiency can be improved.

[0061] In some embodiments of the present utility model, such as Figure 1 andFigure 3 As shown in the figure, the mobile phone heat dissipation device 100 further includes a heat insulation plate 60, and the heat insulation plate 60 is arranged on the side of the heat sink 32 close to the second heat conduction part 22.

[0062] The heat insulation plate 60 can be a plate made of a material that can isolate heat transfer. Its material can be the same as that of the previous thermal insulation layer, which will not be elaborated here. The two ends of the heat insulation plate 60 can be connected to the opposite ends of the housing 10, so as to isolate the heat sink 32 and the area where the mobile phone camera is located, thereby reducing the heat transfer between the area where the mobile phone camera is located and the area where the heat sink 32 is located.

[0063] Since the heat sink 32 has a relatively large amount of heat and a relatively high temperature, and the second heat conduction part 22 needs to dissipate heat around the camera on the back of the mobile phone, the heat insulation plate 60 can isolate the area where the second heat conduction part 22 is located and the area where the heat dissipation component 30 is located, avoiding the heat of the heat sink 32 from spreading around when the fan 33 works. That is, the heat insulation plate 60 prevents the heat of the heat sink 32 from blowing towards the second heat conduction part 22, reducing the influence of the heat dissipated by the heat sink 32 on the heat dissipation of the second heat conduction part 22, so that the second heat conduction part 22 can maintain a good heat dissipation and cooling effect on the area around the camera of the mobile phone.

[0064] In some embodiments of the present invention, as Figure 1 and Figure 4 shown, a receiving cavity 103 is provided in the housing 10. The refrigeration sheet 31, the heat sink 32, the fan 33, the battery 40 and the charge and discharge component 50 are arranged in the receiving cavity 103. The housing 10 is provided with an air inlet 10a and a heat dissipation outlet 10b communicating with the receiving cavity 103. The air inlet 10a is close to the fan 33, and the heat dissipation outlet 10b is close to the heat sink 32. The open end 102 communicates the receiving cavity 103 and the mobile phone fixing groove 101.

[0065] It can be understood that in the above solution, the refrigeration sheet 31, the heat sink 32, the fan 33, the battery 40 and the charge and discharge component 50 are all placed inside the housing 10, which can play a role in protecting the refrigeration sheet 31, the heat sink 32, the fan 33, the battery 40 and the charge and discharge component 50, and can better fix the above components to prevent the above components from detaching from the housing 10. On the other hand, placing the above components inside the housing 10 can also make the overall mobile phone heat dissipation device 100 more beautiful, with a more concise appearance and convenient for users to use.

[0066] Optionally, the air inlet 10a is arranged on the back of the housing 10. The back of the housing 10 has a relatively large area and fewer components, which is convenient for opening the air inlet 10a and has good manufacturability.

[0067] Optionally, the air inlet 10a can be a rectangular grid hole (see Figure 6 ), a circular grid hole (see Figure 7 ), etc.

[0068] Optionally, as shown in Figure 1 , Figure 2 and Figure 3 , the heat dissipation openings 10b can be provided at both ends of the housing 10 in the width direction. The width direction of the housing 10 can be the Figures 1 to 3 left - right direction. In this way, the distance between the heat sink 32 and the heat dissipation openings 10b is relatively short, and the heat of the heat sink 32 can be quickly discharged from the housing 10, avoiding the heat staying in the housing 10 for a long time, which is beneficial to improving the heat dissipation efficiency of the heat dissipation assembly 30.

[0069] In some embodiments of the present utility model, as shown in Figures 1 to 4 , Figure 6 and Figure 7 , the second heat conduction part 22 is provided with a camera avoidance hole 22a, the housing 10 is provided with an opening 10d communicating the accommodation cavity 103 and the mobile phone fixing groove 101, the housing 10 is provided with a lens hole 10c communicating the accommodation cavity 103 and a cover plate 70 capable of covering the lens hole 10c, and the lens hole 10c, the opening 10d and the camera avoidance hole 22a are corresponding.

[0070] Through the lens hole 10c, the opening 10d and the camera avoidance hole 22a, when the mobile phone heat dissipation device 100 is in use, it can ensure that the mobile phone camera can normally perform the imaging work, ensuring the functionality of the mobile phone. The cover plate 70 can open the lens hole 10c when the mobile phone needs the camera to work, and close the lens hole 10c when the camera does not need to work, so as to reduce the entry of dust and other impurities into the housing 10, which is beneficial to ensuring that the internal components of the housing 10 can be in a good working environment, and is also beneficial to keeping the mobile phone camera always in a clean state, so that clearer images can be captured when the mobile phone camera works, and the user experience can be improved.

[0071] Optionally, the openable and closable manner between the cover plate 70 and the housing 10 can be but is not limited to the magnetic attraction manner, the hinge manner, the bolt manner, etc. Optionally, the shapes of the lens hole 10c and the cover plate 70 can be but are not limited to circular, square, oval, etc. As shown in Figure 5 , the shapes of the lens hole 10c and the cover plate 70 are square.

[0072] In some embodiments of the present utility model, as shown in Figures 1 to 4 , Figures 5 to 8 , the housing 10 includes a main frame 11 and a rear cover 12. The main frame 11 is provided with a mobile phone fixing groove 101, and a receiving groove is provided on a side of the main frame 11 away from the mobile phone fixing groove 101.
