Description

[0002] With the continuous development of electronic technology, the high integration of smart terminals such as mobile phones and tablets has become an inevitable trend. As the performance of smart terminals continues to improve, the increased power consumption due to the increased integration of chips and the higher requirements for user experience have placed higher demands on the heat dissipation of smart terminals. Therefore, improving the heat dissipation performance of smart terminals has always been a focus of industry attention.

[0003] Currently, most terminal devices such as mobile phones and tablets use internal heat dissipation materials such as heat pipes and water-based copper foil for efficient temperature equalization. However, since the surface heat dissipation is achieved through natural convection, the overall heat dissipation capacity is limited. As power consumption increases, the surface temperature of the device continues to rise, affecting the user experience. Some terminal devices use fans for forced cooling, but this places strict requirements on the internal structural space. Others use external auxiliary cooling devices to dissipate heat. These external auxiliary cooling devices are usually large in size, have high power consumption, require an external power supply, and are inconvenient to carry. Summary of the Invention

[0041] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0043] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0044] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0045] like Figure 1 , 2As shown, this invention provides a heat dissipation shell that can be used as a protective case for a mobile phone. The heat dissipation shell specifically includes a housing 10, an energy storage component, a switching component 30, and a pump. The housing 10 includes a first region 11 and a second region 12. A first phase change material filler 111 is distributed in the first region 11, and a second phase change material filler 121 is distributed in the second region. The phase change temperature of the second phase change material filler 121 is different from that of the first phase change material filler 111, wherein the phase change temperature of the first phase change material filler 111 is higher than that of the second phase change material filler 121. Specifically, the phase change temperature of the first region 11 is directly opposite the heat source area of ​​the phone's motherboard, meaning the first phase change material filler 111 faces the relatively high-temperature area of ​​the phone. The second region 12 faces other areas of the phone, meaning the second phase change material filler 121 faces the relatively low-temperature area of ​​the phone. For example, the phase change temperature of the first phase change material filler 111 is 40°C to meet the requirements of human body temperature difference comfort, and the phase change temperature of the second phase change material filler 121 is 36°C, close to the temperature of human hands, to prevent the phase change material from absorbing the temperature of human hands and reducing its heat absorption time. A fluid channel 13 is also provided inside the housing 10, which runs through the first region 11 and the second region 12. The fluid channel 13 contains a heat-conducting medium. When the heat-conducting medium in the fluid channel 13 flows through the first region 11 and the second region 12, it can exchange heat with the first phase change material filler 111 and the second phase change material filler 121, respectively. The energy storage component includes a spring barrel 21 and a oscillating element 22. The oscillating element 22 is connected to the power input end of the spring barrel 21. The oscillating element 22 can continuously oscillate when the heat sink is in a shaking or moving state, driving the power input end of the spring barrel 21 to rotate, so as to store the collected mechanical energy in the spring barrel 21. The pump is connected to the power output end of the spring barrel 21. The rotation of the power input end of the spring barrel 21 drives the pump to operate. The inlet and outlet ends of the pump are respectively connected to the two ends of the fluid channel 13. It is used to drive the heat transfer medium in the fluid channel 13 to flow in the loop formed by the fluid channel 13 and the pump, so that the heat transfer medium can continuously interact with the first... The first phase change material filler 111 and the second phase change material filler 121 exchange heat. The switch assembly 30 is used to control the rotation or stop of the power output end of the spring barrel 21. When the mobile phone is in use, the switch assembly 30 is turned on, so that the power output end of the spring barrel 21 can rotate and drive the pump to run. When the mobile phone is not in use, the switch assembly 30 is turned off, and the switch assembly 30 controls the power output end of the spring barrel 21 to stop rotating, the pump stops working, and the heat transfer medium in the fluid channel 13 stops flowing. At this time, if the mobile phone is in a moving state with the user, the swinging part 22 continues to swing, so that the spring barrel 21 can continuously collect mechanical energy.

[0046] The first phase change material filler 111 of the present invention is a high-temperature phase change microcapsule, and the second phase change material filler 121 is a low-temperature phase change microcapsule. The phase change material inside the microcapsule can be selected from lauric acid, paraffin, eutectic salt composite materials, etc. Placing the phase change material in the shell 10 in the form of microcapsules allows the phase change material to better integrate with the shell 10, which can increase the heat exchange area of ​​the phase change material and improve the temperature uniformity of the surface of the shell 10.

[0047] This invention achieves better temperature uniformity on the surface of the heat sink by continuously exchanging heat with different phase change materials through a heat-conducting medium. It is suitable for the heat dissipation needs of intermittently operating electronic devices, improves the heat dissipation capacity of electronic devices in high-power scenarios, and provides power to the pump after storing mechanical energy through the spring box. No power supply is required, and it is small in size and easy to carry.

[0048] In a preferred embodiment, the present invention has a mounting shell 50 fixedly connected to the outer surface of the housing 10, and a cavity is formed inside the mounting shell 50, in which the spring box 21, the oscillating member 22, and the switch assembly 30 are all installed. A through hole is provided on the bottom wall of the mounting shell 50. The through hole extends from one side of the bottom wall of the mounting shell 50 to the other side. That is, the through hole only forms an interface on both sides of the bottom of the mounting shell 50 and does not communicate with the inner cavity of the mounting shell 50. The two ends of the fluid channel 13 are respectively connected to the interfaces at both ends of the through hole. Thus, the fluid channel 13 and the through hole form a loop, and the heat transfer medium can circulate in the loop. The pump is a gear pump 40. The gear pump 40 includes gears 41 and 42 arranged opposite to each other. The gears 41 and 42 can be installed inside the bottom wall of the mounting shell 50, and the gears 41 and 42 are respectively placed on both sides of the through hole. The gear 41 is connected to the power output end of the spring box 21. The spring box 21 drives the gear 41 to rotate, which in turn causes the gears 41 and 42 on the gear pump to rotate simultaneously, driving the heat transfer medium located in the through hole to flow, so that the heat transfer medium can circulate in the loop.

[0049] To facilitate the installation of the gear pump 40, the mounting housing 50 of the present invention includes a base plate 52 and a mounting plate 53. The mounting plate 53 is tightly fitted to the lower surface of the base plate 52, and both the outer periphery of the base plate 52 and the periphery of the mounting plate 53 are tightly fitted with the housing 10. A groove 531 extending from one side to the other is provided on the upper surface of the mounting plate 53. After the mounting plate 53 and the base plate 52 are assembled together, the inner surface of the groove 531 and the lower surface of the base plate 52 form the aforementioned through hole. Gears 41 and 42 of the gear pump 40 are both mounted on the mounting plate 53 and placed on both sides of the groove 531. During assembly, gears 41 and 42 of the gear pump 40 are first assembled onto the mounting plate 53, and then the mounting plate 53 is fixed to the lower surface of the base plate 52. While fixing, the mating surfaces of the mounting plate 53 and the base plate 52 are sealed to form an assembly. Then the formed assembly is assembled with the housing 10, and the periphery of the mounting plate 53 and the base plate 52 is sealed at the positions where they mate with the housing 10.

[0050] In addition, such as Figure 3 , 4As shown, an output gear 212 is provided at the power output end of the mainspring barrel 21. The output gear 212 is located on the periphery of the mainspring barrel 21. A transmission component is connected between the output gear 212 and the gear 41 of the gear pump 40. Through the transmission component, the power stored in the mainspring barrel 21 is transmitted to the gear 41 through the output gear 212 to provide power to the gear pump 40. The transmission assembly specifically includes a first transmission gear 61, a second transmission gear 62, a third transmission gear 63, a fourth transmission gear 64, and a fifth transmission gear 65 mounted on the mounting housing 50. The first transmission gear 61 meshes with the output gear 212. The second transmission gear 62 is fixed to the first transmission gear 61 and coaxially arranged so that the two rotate synchronously. The third transmission gear 63 meshes with the second transmission gear 62. The fourth transmission gear 64 is fixed to the third transmission gear 63 and coaxially arranged so that the two rotate synchronously. The fifth transmission gear 65 meshes with the fourth transmission gear 64. Furthermore, the fifth transmission gear 65 is synchronously connected to the gear 41 of the gear pump 40. When the output gear 212 of the spring box 21 rotates, the power is transmitted sequentially through the first transmission gear 61, the second transmission gear 62, the third transmission gear 63, the fourth transmission gear 64, and the fifth transmission gear 65 to the gear 41 of the gear pump 40. The diameter of the first transmission gear 61 is smaller than the diameter of the output gear 212, the diameter of the second transmission gear 62 is larger than the diameter of the first transmission gear 61, the diameter of the third transmission gear 63 is smaller than the diameter of the second transmission gear 62, the diameter of the fourth transmission gear 64 is larger than the diameter of the third transmission gear 63, and the diameter of the fifth transmission gear 65 is smaller than the diameter of the fourth transmission gear 64. This creates a multi-stage transmission structure between the output gear 212 and gear 41. When the spring barrel 21 releases the stored power, it enables gears 41 and 42 of the gear pump 40 to rotate at a sufficiently high speed, thereby creating a partial vacuum. This continuously draws in and expels the heat-conducting medium in fluid form, ensuring that the heat-conducting medium flows smoothly and rapidly in the aforementioned circuit. Of course, to enable the spring barrel 21 to provide power to the gear pump 40 and to allow gear 41 of the gear pump 40 to achieve a high rotational speed, other transmission components can be used to connect gear 41 to the output gear 212.

[0051] See Figure 6 , 7In another preferred embodiment, the present invention has a top cover 51 on the top of the mounting housing 50. The top cover 51 is detachably fixed to the mounting housing 50. The aforementioned switch assembly 30, spring barrel 21, oscillating member 22, and transmission assembly are all covered below the top cover 51. The trigger end of the switch assembly protrudes from the upper surface of the top cover 51, so that the power output end of the spring barrel 21 can be controlled to rotate or stop by pressing the trigger end of the switch assembly 30 from the outside. Specifically, the output gear 212 of the spring barrel 21 can be controlled to rotate or stop. Specifically, the switch assembly 30 includes a fixed housing 301 fixedly connected inside the mounting housing 50 and a button 302. The button 302 is movably installed inside the fixed housing 301, and the top of the button 302 protrudes from the top of the fixed housing 301. At the same time, a top cover 51 is provided on the top cover 51. The button 302 has a hole extending to the outside of the mounting housing 50. A limiting rod 303 protrudes from the periphery of the button 302. The limiting rod 303 passes through a pre-set hole 309 on the fixed housing 301. Pressing the button 302 allows the limiting rod 303 to move along the hole 309 in the height direction. When the limiting rod 303 moves downward with the button 302 to the first position where it abuts against the lower edge of the hole 309, the rotation of the output gear 212 of the limiting rod 303 acts as a limit, thereby controlling the power output end of the spring box 21 to stop rotating. When the limiting rod 303 moves upward with the button 302 to the second position where it abuts against the upper surface of the hole 309, the limiting rod 303 no longer restricts the rotation of the output gear 212, and the power of the spring box 21 is in a state of free release, that is, driving the gear 41 of the gear pump 40 to rotate. The switch assembly 30 also includes a linkage gear 31 pivotally connected within the mounting housing 50. The linkage gear 31 meshes with the output gear 212. A swing rod 311 is provided on the linkage gear 31. The swing rod 311 cooperates with a limit rod 303. Specifically, when the limit rod 303 is in the first position, the limit rod 303 and the swing rod 311 are at the same height, and the swing rod 311 abuts against the limit rod 303. The limit rod 303 limits the rotation of the swing rod 311, thereby limiting the rotation of the linkage gear 31, and the output gear 212 cannot rotate freely. When the limit rod 303 is in the second position, the limit rod 303 separates from the swing rod 311, and the swing rod 311 can rotate freely, thereby allowing the output gear 212 to rotate freely.A spring 305 and a sliding rod 304 are also provided between the fixed housing 301 and the button 302. When the spring 305 is compressed, it always pushes the button 302 upward. A sliding groove 306 is provided on the button 302. The sliding groove 306 is connected end to end to form a closed structure. The lower end of the sliding rod 304 is hinged to the fixed housing 301, and the upper end is embedded in the sliding groove 306 and can slide along the extension direction of the sliding groove 306. The sliding groove 306 includes a first segment 3061, a second segment 3062, and a third segment 3063 arranged in sequence. The second segment 3062 is an arc shape with a downward concave middle. The middle of the second segment 3062 is provided with a first locking part for locking the other end of the sliding rod 304. The top parts of the first segment 3061 and the third segment 3063 are respectively Both ends and the bottom end of the second segment 3062 extend downward and connect with each other. At the position where the bottom of the first segment 3061 and the third segment 3063 connect, a second locking part is formed for locking the other end of the sliding rod 304. When the other end of the sliding rod 304 slides clockwise to the first locking part, the button 302 is in a lower position, that is, the limiting rod 303 on the button 302 is in the first position. At this time, the other end of the sliding rod 304 is locked in the first locking part. When the other end of the sliding rod 304 slides clockwise to the second locking part, the button 302 is in a higher position. At this time, the limiting rod 303 on the button 302 is in the second position. At this time, the other end of the sliding rod 304 is locked in the second locking part.Specifically, when the sliding rod 304 is in the first locking position, because the spring 305 always pushes the button 302 outward, the sliding rod 304 abuts against point a, the middle of the inner edge of the second segment 3062. At the same time, point b, the outer edge of the second segment 3062, protrudes towards the middle of the groove 306 and is located to the left of point a. Points b and a limit the other end of the sliding rod 304. At this time, when the button 302 is pressed, due to the limiting effect of point b, the other end of the sliding rod 304 rotates clockwise. The sliding rod 304 slides along the slide groove 306, meaning the other end of the sliding rod 304 slides to the right along the second segment 3062. Since point g, where the inner edge of the second segment 3062 connects to the inner edge of the third segment 3063, is located to the left of point h, where the outer edge of the second segment 3062 connects to the outer edge of the third segment 3063, when it slides to the position where the second segment 3062 connects to the third segment 3063, the pressing force on the button 302 is released. Under the action of the spring 305, the other end of the sliding rod 304 slides clockwise downwards to the... At the junction of the third segment 3063 and the first segment 3061, the third segment 3063 is engaged by the second locking part at that location. Under the action of the spring 305, the other end of the sliding rod 304 is engaged in the recessed area formed by the outer edge of the junction of the third segment 3063 and the first segment 3061, and the button 302 is in a high position. Since the center point d of the recessed area formed by the outer edge of the junction of the third segment 3063 and the first segment 3061 is located to the left of the center point c of the convex area formed by the inner edge of the junction of the third segment 3063 and the first segment 3061, the button 302 is in a high position. Due to the limiting effect of point c, when button 302 is pressed, the other end of the sliding rod 304 can only slide clockwise, that is, slide upward along the first segment 3061. Since point e, where the inner edge of the first segment 3061 connects with the inner edge of the second segment 3062, is located to the left of point f, where the outer edge of the first segment 3061 connects with the outer edge of the second segment 3062, when the pressing force on button 302 is released, the other end of the sliding rod 304 slides clockwise to the first locking part in the middle of the second segment 3062.

[0052] In this invention, the button 302 is not limited to protruding from the top cover 51 of the mounting housing 50, but can also protrude from the side of the mounting housing 50. The switch assembly is not limited to the above-mentioned pressing button, but can also be a toggle or rotation button. For example, when the trigger end of the switch is toggled to one position, the component on the switch moves to a position where it engages with the tooth groove of the output gear 212. When toggled to another position, the component on the switch assembly is separated from the output gear 212, and the rotation of the output gear 212 is no longer restricted.

[0053] Combination Figure 5The aforementioned oscillating element 22 is a counterweight. An input gear 211 is provided at the power input end of the spring barrel 21. A gear 213 is fixed at the rotating end of the counterweight. Simultaneously, a driving gear 214 is installed on the spring barrel 21. Gear 213 meshes with the driving gear 214, thereby synchronously connecting the counterweight and the driving gear 214. A transmission element 215 is provided between the driving gear 214 and the input gear 211. This transmission element 215 includes a transmission rod 2151 and a transmission rod 2152. One end of the transmission rod 2151 and the transmission rod 2152 is connected to a connecting part 2153, and the other end is respectively placed on the input... The gear 211 has two outer peripheral sides, and the connecting part 2153 is connected to the driving gear 214 through a pivot 2154. The central axis of the pivot 2154 is offset from the central axis of the driving gear 214. A ratchet 21511 is provided on the transmission rod 2151, and a ratchet 21521 is provided on the transmission rod 2152. The ratchet 21511 and the ratchet 21521 are arranged opposite to each other on the outer edge of the input gear 211, and both of them mesh with the outer tooth groove of the input gear 211. In the circumferential direction of the input gear 211, the ratchet 21511 and the ratchet 21521 face the same direction. Figure 5a , 5b This illustrates the state in which the oscillating element 22 drives the input gear 211 to rotate when it oscillates. Figure 5a With the center O1 of the input gear 211, the center O2 of the drive gear 214, and the center O3 of the pivot 2154 collinear on a straight line O, and center O3 being far from center O1, in this state, when the drive gear 214 rotates clockwise (dashed arrow), ratchet 21511 pulls the input gear 211, and simultaneously ratchet 21521 pushes the input gear 211, causing the input gear 211 to rotate clockwise. When it rotates to... Figure 5b In the indicated state, the center O1 of the input gear 211, the center O2 of the driving gear 214, and the center O3 of the pivot 2154 are on the same straight line O, and the center O3 is closer to the center O1. Figure 5b In the indicated state, when the drive gear 214 continues to rotate clockwise, neither ratchet 21511 nor ratchet 21521 will cause the input gear 211 to rotate. Then, the drive gear 214... Figure 5b The indicated state is rotated clockwise to... Figure 5a When the indicated state continues to rotate, ratchet 21511 pulls input gear 211 again, and simultaneously ratchet 21521 pushes input gear 211 again. That is, when the driving gear 214 rotates clockwise, it can cause the input gear 211 to rotate clockwise to tighten the spring box 21. When the driving gear 214 is in the indicated state and continues to rotate, ratchet 21511 pulls input gear 211 again, and ratchet 21521 pushes input gear 211 again. Figure 5a In the state shown, when rotated counterclockwise (solid arrow), neither ratchet 21511 nor ratchet 21521 will cause the input gear 211 to rotate. When rotated to... Figure 5bIn the state shown, when the drive gear 214 continues to rotate counterclockwise, the ratchet 21521 pushes the input gear 211, and at the same time, the ratchet 21511 pulls the input gear 211 to rotate clockwise. That is to say, no matter how the aforementioned weight swings, it can drive the input gear 211 to rotate clockwise to tighten the spring box 21. Thus, when the mobile phone is not in use, the swinging of the weight can tighten the spring box 21 while the user is carrying the mobile phone. During the movement, the energy generated by the vibration can be stored in the spring box 21. When the user is using the mobile phone, the spring box 21 can input more mechanical energy to drive the gear pump 40.

[0054] In other embodiments, the heat sink of the present invention may further include a drive assembly connected to the input end of the mainspring barrel 21. This drive assembly can manually rotate the input gear 211 of the mainspring barrel 21 to tighten the mainspring barrel 21. When the mechanical energy stored inside the mainspring barrel 21 is insufficient, the mainspring barrel 21 can be manually tightened. Specifically, the drive assembly may include a transmission rod and a drive component. The transmission rod is pivotally connected to the mounting shell 50, with one end connected to the power input end of the mainspring barrel 21. The drive component is located outside the mounting shell 50 and connected to the other end of the transmission rod. Rotating the drive component drives the transmission rod to rotate, thereby tightening the mainspring barrel 21. The aforementioned driving component can be a ring located outside the mounting housing 50. A drive shaft is pivotally connected to the mounting housing 50, and the inner end of the drive shaft meshes with a drive rod. The two can mesh via bevel gears to change the transmission direction. The ring is rotatably connected to the drive shaft. By rotating the ring, the drive shaft can be rotated, thereby tightening the spring barrel 21. The ring also serves the purpose of making it convenient for the user to carry the mobile phone, and when not in use, the ring can be folded to the outside of the mounting housing 50. In this way, the present invention can both automatically collect mechanical energy and manually store energy into the spring barrel 21.

[0055] The heat dissipation shell of the present invention can be used as a protective case for the outside of a mobile phone, as described above, or it can be used directly as the outer shell of the mobile phone to dissipate heat from the internal electronic devices. Of course, the heat dissipation shell of the present invention is not limited to being a protective case for mobile phones; it can also be used as a protective case for other electronic devices such as tablet computers. The electronic device of the present invention includes the aforementioned heat dissipation shell, and using the aforementioned heat dissipation shell directly as the outer shell of the electronic device can result in mobile phones, tablet computers, laptops, smart wearable devices, etc.
