热管400连接所述扬声器箱200和所述热源器件300，用以将所述热源器件300在工作过程中产生的热量传导至所述扬声器箱200中。The heat pipe 400 connects the speaker box 200 and the heat source device 300 to conduct the heat generated by the heat source device 300 in the working process to the speaker box 200.
具体的，所述热管400包括冷凝端1a、蒸发端2a以及传导部3a。Specifically, the heat pipe 400 includes a condensing end 1a, an evaporating end 2a, and a conducting part 3a.

More preferably, the condensing end 1a and the housing 201 are integrally injection-molded.
进一步的，所述冷凝端1a包括第一段101a和第二段102a，所述第一段101a设置于所述前声腔205内并与所述传导部3a连接，所述第二段102a设置于所述导声通道203内并与所述第一段101a远离所述传导部3a一侧。Further, the condensing end 1a includes a first section 101a and a second section 102a. The first section 101a is disposed in the front acoustic cavity 205 and connected to the conducting portion 3a, and the second section 102a is disposed at Inside the sound guide channel 203 and away from the first section 101a from the conducting portion 3a.
所述出声组件500包括支撑件51以及导热件52，所述支撑件51固定于所述壳体201，所述导热件52嵌设于所述支撑件51。The sound-emitting assembly 500 includes a support 51 and a heat conduction element 52. The support 51 is fixed to the housing 201, and the heat conduction element 52 is embedded in the support 51.
在本实施方式中，所述支撑件51设有贯穿其上的通孔510，所述导热件52包括固定于所述支撑件51外侧的导热部521以及由所述导热部521远离所述壳体201一侧凸出延伸并插设于所述通孔510内的延伸壁522；所述导热部521抵接于所述壳体201并完全覆盖所述出声孔204，且所述导热部521与所述冷凝端1a连接；所述延伸壁522设有贯穿其上的到导声孔520，所述导声孔520将所述出声孔204与外界连通；所述第二段102a抵接于所述导热部521，用以将冷凝端1a的热量传导至所述导热部521。In this embodiment, the supporting member 51 is provided with a through hole 510 penetrating therethrough, and the heat conducting member 52 includes a heat conducting portion 521 fixed to the outside of the supporting member 51 and a heat conducting portion 521 away from the shell. One side of the body 201 protrudes and extends and is inserted into the extension wall 522 in the through hole 510; the heat conducting portion 521 abuts on the housing 201 and completely covers the sound hole 204, and the heat conducting portion 521 is connected to the condensing end 1a; the extending wall 522 is provided with a sound guide hole 520 penetrating therethrough, and the sound guide hole 520 connects the sound hole 204 with the outside; the second section 102a resists It is connected to the heat-conducting part 521 for transferring the heat of the condensing end 1 a to the heat-conducting part 521.
该设置使得冷凝端1a靠近前腔210一侧与前腔210内空气直接接触，在该侧，冷凝端1a将热量传导至所述前腔210中，所述振膜2021振动推动所述前腔210内的空气通过所述导声孔520与外界流通。具体的，所述振膜2021振动时在所述前声腔205体积的变化：所述前声腔205体积变小时，所述振膜2021通过所述出声孔204将所述前声腔205内的部分空气排出至外界；而所述前声腔205体积变大时，所述振膜2021通过所述出声孔204将外界的空间吸入至所述前声腔205内；以上过程使所述前声腔205内的空气与外界的空气实现对流。所述振膜2021的振动使所述前声腔205内的热量随空气流通散发至所述壳体201外，从而实现了对所述热源器件300的散热，使得所述扬声器装置100的散热效果好；同时，由于冷凝端1a通过第二段102a与导热部521连接，即冷凝端1a可直接通过热传导的方式将热量向导热件52传导，并通过导热件52向外散发，有效地增加了散热面积，优化了散热效果。上述结构使得冷凝端1a靠近所述前腔210一侧同时通过热辐射和热传导的方式进行散热，提高了散热效率，从而优化了扬声器装置100的散热性能。This arrangement makes the side of the condensation end 1a close to the front cavity 210 directly contact the air in the front cavity 210. On this side, the condensation end 1a conducts heat to the front cavity 210, and the diaphragm 2021 vibrates and pushes the front cavity. The air in 210 circulates with the outside through the sound guide hole 520. Specifically, the change in the volume of the front acoustic cavity 205 when the diaphragm 2021 vibrates: the volume of the front acoustic cavity 205 becomes smaller, and the diaphragm 2021 passes through the sound outlet 204 to reduce the volume of the front acoustic cavity 205 When the volume of the front acoustic cavity 205 becomes larger, the diaphragm 2021 sucks the external space into the front acoustic cavity 205 through the sound outlet 204; the above process makes the front acoustic cavity 205 The air is convective with the outside air. The vibration of the diaphragm 2021 causes the heat in the front acoustic cavity 205 to radiate to the outside of the housing 201 along with the air circulation, thereby realizing the heat dissipation of the heat source device 300, so that the speaker device 100 has a good heat dissipation effect. At the same time, because the condensing end 1a is connected to the heat conducting portion 521 through the second section 102a, the condensing end 1a can directly conduct heat through the heat conduction means 52, and dissipate it through the heat conducting part 52, effectively increasing the heat dissipation The area optimizes the heat dissipation effect. The above-mentioned structure enables the condensing end 1a to be close to the front cavity 210 to simultaneously dissipate heat by means of heat radiation and heat conduction, which improves the heat dissipation efficiency, thereby optimizing the heat dissipation performance of the speaker device 100.
蒸发端2a将热源器件300的热量通过传导部3a传导冷凝端1a，冷凝端1a与前腔210连接，扬声器箱200的前腔210发生时形成主动气流交换，从使得冷凝端1a的热量通过气流交换快速散出。The evaporating end 2a conducts the heat of the heat source device 300 through the conduction part 3a to the condensing end 1a. The condensing end 1a is connected to the front cavity 210. When the front cavity 210 of the speaker box 200 occurs, an active airflow exchange is formed, so that the heat of the condensing end 1a passes through the airflow. The exchange quickly dissipated.
蒸发端2a与热源器件300相连，将热源器件300的热量转移至热管400内部的换热工质，并传导至冷凝端1a，换热工质在热管400内部蒸发冷凝进行热量传递和转移，达到散热的目的。The evaporating end 2a is connected to the heat source device 300, and transfers the heat of the heat source device 300 to the heat exchange working fluid inside the heat pipe 400, and conducts it to the condensing end 1a. The heat exchange working fluid evaporates and condenses inside the heat pipe 400 for heat transfer and transfer. The purpose of heat dissipation.
进一步的，所述导热部521包括夹设于所述支撑件51靠近所述前腔210一侧与所述壳体201之间的第一导热板5211和由所述第一导热板5211边缘沿所述支撑件外侧向远离所述壳体201的方向弯折延伸的第二导热板5212；所述第一导热板5211抵接于所述壳体201并覆盖所述出声孔204，所述第二段102a延伸至所述壳体201外并与所述第一导热板5211连接，所述延伸壁522由所述第一导热板5211沿靠近所述通孔510的方向延伸。Further, the heat conduction portion 521 includes a first heat conduction plate 5211 sandwiched between a side of the support 51 close to the front cavity 210 and the housing 201, and a first heat conduction plate 5211 along the edge of the first heat conduction plate 5211. The outer side of the support member is bent and extended in a direction away from the housing 201, and the second heat conducting plate 5212 extends; the first heat conducting plate 5211 abuts on the housing 201 and covers the sound hole 204, the The second section 102 a extends to the outside of the housing 201 and is connected to the first heat conducting plate 5211, and the extension wall 522 extends from the first heat conducting plate 5211 in a direction close to the through hole 510.
需要说明的是，所述第一导热板5211与所述第二导热板5212为分体结构；当然，为了导热件的装配更加方便，第一导热板与第二导热板为一体成型结构也是可以的。It should be noted that the first heat-conducting plate 5211 and the second heat-conducting plate 5212 are separate structures; of course, in order to make the assembly of the heat-conducting element more convenient, the first heat-conducting plate and the second heat-conducting plate may be an integral structure. of.
更优的，为了提高所述出声组件500装配的可靠性，所述支撑件51与所述导热件52为一体成型结构。More preferably, in order to improve the reliability of the assembly of the sound output assembly 500, the supporting member 51 and the heat conducting member 52 are integrally formed.
更进一步的，所述导声孔520的直径小于所述出声孔204的直径，使得在所述导声孔520的空气流速较大，其流动的絮乱程度较大，有效地提升热管400与空气之间的换热系数，更进一步地提高了扬声器装置100的散热性能。Furthermore, the diameter of the sound guide hole 520 is smaller than the diameter of the sound outlet 204, so that the air flow rate in the sound guide hole 520 is relatively large, and the degree of flow is relatively large, which effectively raises the heat pipe 400. The heat exchange coefficient with the air further improves the heat dissipation performance of the speaker device 100.
值得一提的是，所述延伸壁522包括至少两个且相互间隔设置，所述导声孔520与所述延伸壁522一一对应设置，每一所述导声孔520均与所述出声孔204正对且连通。It is worth mentioning that the extension walls 522 include at least two and are spaced apart from each other. The sound guide holes 520 and the extension walls 522 are arranged in one-to-one correspondence, and each sound guide hole 520 is connected to the outlet The sound holes 204 are directly opposite and connected.
需要说明的是，所述振膜2021振动可以是发声形式或者不发声形式，均可以将传导至所述前声腔205内的热量随空气流通散发至外界。从而使所述扬声器箱200可以专门执行散热的工作。It should be noted that the vibration of the diaphragm 2021 may be in a sounding form or a non-sounding form, both of which may dissipate the heat conducted into the front acoustic cavity 205 to the outside along with air circulation. Thus, the speaker box 200 can specifically perform heat dissipation work.
具体的，对所述扬声器箱200输入较低频率的脉冲信号，该信号在所述扬声器箱200产生的低频声音不会被人耳听到。在本实施方式中，输入较低频率低于1000Hz。在具体应用上，所述扬声器箱200不执行音乐播放任务时可单独播放该脉冲信号；所述扬声器箱200在执行音乐播放任务时也可将该脉冲信号叠加进音乐信号中。因为该信号是超低频的脉冲信号，将不会被人耳听到，不影响正常听音效果。Specifically, a lower frequency pulse signal is input to the speaker box 200, and the low frequency sound generated by the signal in the speaker box 200 will not be heard by human ears. In this embodiment, the input lower frequency is lower than 1000 Hz. In specific applications, the speaker box 200 can play the pulse signal alone when it is not performing a music playback task; the speaker box 200 can also superimpose the pulse signal into the music signal when the speaker box 200 is performing a music playback task. Because the signal is an ultra-low frequency pulse signal, it will not be heard by the human ear and will not affect the normal listening effect.
本实施方式中，所述热源器件300为处理器和电池中的任意一种，其可以根据实际的情况进行具体的设置。In this embodiment, the heat source device 300 is any one of a processor and a battery, which can be specifically set according to actual conditions.
需要指出的是，所述热管400的结构形式是不限，其可以为呈实心的由导热金属材料制成的呈实心的热管结构；也可以为内部设有通道且通道内填充有换热工质的液冷管结构，而该液冷管结构内部的通道多为等当量直径。It should be pointed out that the structure of the heat pipe 400 is not limited. It can be a solid heat pipe structure made of a thermally conductive metal material; it can also have a channel inside and filled with heat exchangers. Quality liquid-cooled tube structure, and the channels inside the liquid-cooled tube structure are mostly equivalent diameters.
而液冷管与扬声器箱结合形成的扬声器装置在散热过程中，热源较高的热流密度在与换热工质高效换热系数之间较为对等，在热量迅速传导到换热工质以后，高效的传热效率要求换热工质迅速冷凝与蒸发，换热工质的相变瞬间造成的其换热系数数量级上的提升。而相变势必会造成换热工质体积上的变化，冷凝时体积变小，蒸发时体积增大。In the heat dissipation process of the speaker device formed by the combination of the liquid cooling tube and the speaker box, the higher heat flux density of the heat source is relatively equal to the efficient heat transfer coefficient of the heat exchange working medium. After the heat is quickly transferred to the heat exchange working medium, Efficient heat transfer efficiency requires rapid condensation and evaporation of the heat exchange working fluid, and the instantaneous phase change of the heat exchange working fluid causes an order-of-magnitude increase in its heat transfer coefficient. The phase change will inevitably cause a change in the volume of the heat exchange working fluid, the volume becomes smaller during condensation, and the volume increases during evaporation.
但由于液冷管内部的通道当量直径相同，在换热工质物态变化期间，其湍流效果在冷凝端大大下降，使得其换热效果有限，而且在热管的冷凝端与外界空气进行热量交换，限制了空气的传热效果，这就造成了冷凝端与蒸发端两端换热不均，最终空气较低的换热效果制约了整体换热性能。However, since the equivalent diameters of the channels inside the liquid cooling tube are the same, the turbulence effect at the condensing end is greatly reduced during the state of the heat exchange working fluid, which makes the heat exchange effect limited, and the condensing end of the heat pipe exchanges heat with the outside air. , Which limits the heat transfer effect of the air, which causes uneven heat exchange between the condensing end and the evaporating end, and ultimately the lower heat exchange effect of the air restricts the overall heat exchange performance.
上述的实心的热管结构和设有通道的也液冷管结构的换热效果有限，在此，为了进一步优化扬声器装置的散热性能，更优的，本实用新型的热管400优选为各内部通道的当量直径不同的热管结构，具体的：The above-mentioned solid heat pipe structure and the liquid-cooled pipe structure provided with channels have limited heat exchange effects. Here, in order to further optimize the heat dissipation performance of the loudspeaker device, and more preferably, the heat pipe 400 of the present invention is preferably used for each internal channel Heat pipe structures with different equivalent diameters, specific:
请一并参阅图所示5-6所示，本实用新型提供一种热管400，包括：冷凝端1a、蒸发端2a、传导部3a以及换热工质（图未示）。Please also refer to Figs. 5-6. The present invention provides a heat pipe 400, which includes a condensing end 1a, an evaporating end 2a, a conducting portion 3a, and a heat exchange working medium (not shown).
优选的，所述冷凝端1a、所述蒸发端2a以及所述传导部3a为一体成型结构。Preferably, the condensing end 1a, the evaporating end 2a, and the conducting portion 3a are integrally formed.
所述冷凝端1a内部设有多条冷凝流道11a，每一所述冷凝流道11a包括冷凝进口端111a和冷凝出口端112a。A plurality of condensation flow passages 11a are provided inside the condensation end 1a, and each condensation flow passage 11a includes a condensation inlet end 111a and a condensation outlet end 112a.
所述蒸发端2a内部设有多条蒸发流道21a，且多条所述蒸发流道21a依次首尾相连通形成蒸发流道单元20a，所述蒸发流道单元20a包括蒸发进口端201a和蒸发出口端202a。The evaporation end 2a is provided with a plurality of evaporation channels 21a, and the plurality of evaporation channels 21a are sequentially connected end to end to form an evaporation channel unit 20a. The evaporation channel unit 20a includes an evaporation inlet end 201a and an evaporation outlet.端202a.
本实施方式中，多条所述蒸发流道21a相互平行设置，以在相同体积的空间内使蒸发流道单元20a的路径更长，提高传热效果。In this embodiment, a plurality of the evaporation flow passages 21a are arranged in parallel to each other, so as to make the path of the evaporation flow passage unit 20a longer in the space of the same volume and improve the heat transfer effect.
所述传导部3a的两端分别连接所述冷凝端1a和所述蒸发端2a，用于将蒸发端2a的热量传递至冷凝端1a。The two ends of the conducting part 3a are respectively connected to the condensation end 1a and the evaporation end 2a, and are used to transfer the heat of the evaporation end 2a to the condensation end 1a.
所述传导部3a内部设有第一传导流道31a和第二传导流道32a。The conductive portion 3a is provided with a first conductive flow channel 31a and a second conductive flow channel 32a inside.
所述冷凝流道11a的冷凝出口端112a与所述第一传导流道31a的首端311a连通，所述蒸发流道单元20a的所述蒸发进口端201a与所述第一传导流道31a的尾端312a连通，且所述第一传导流道31a的当量直径由其首端311a向其尾端312a方向逐渐减小。The condensation outlet end 112a of the condensation flow passage 11a is in communication with the first end 311a of the first conduction flow passage 31a, and the evaporation inlet end 201a of the evaporation flow passage unit 20a is connected to the first conduction flow passage 31a. The tail end 312a is connected, and the equivalent diameter of the first conductive flow channel 31a gradually decreases from the head end 311a to the tail end 312a.
所述第二传导流道32a的两端分别与所述冷凝进口端111a和所述蒸发出口端202a连通。Two ends of the second conductive flow channel 32a are respectively communicated with the condensation inlet end 111a and the evaporation outlet end 202a.
所述换热工质填充于所述热管400内，用于传递热量。换热工质在热管400的冷凝端1a与空气进行热量交换，气态的换热工质变为液态，体积变小，在蒸发端2a蒸发压力的推动下，流回蒸发端2a；液态的换热工质吸收来自处理器等热源的热量，蒸发为气态并流至冷凝端1a，从而形成循环，即在所述蒸发流道21a、所述第二传导流道32a、所述冷凝流道11a以及所述第一传导流道31a内循环流动，实现对热源的散热。The heat exchange working fluid is filled in the heat pipe 400 for transferring heat. The heat exchange working medium exchanges heat with the air at the condensing end 1a of the heat pipe 400. The gaseous heat exchange working medium becomes liquid and becomes smaller in volume. Driven by the evaporation pressure of the evaporation end 2a, it flows back to the evaporation end 2a; the liquid heat exchange The working fluid absorbs heat from a heat source such as a processor, evaporates into a gaseous state and flows to the condensing end 1a, thereby forming a cycle, that is, in the evaporation flow channel 21a, the second conduction flow channel 32a, the condensation flow channel 11a and The circulation flow in the first conductive flow channel 31a realizes the heat dissipation of the heat source.
而所述第一传导流道31a的当量直径由其首端311a向其尾端312a方向逐渐减小，该设置使得第一传导流道31a形成在冷凝端1a和蒸发端2a的两端形成一个当量直径渐变的通道结构，从而使得冷凝端1a的液态的换热工质流速提升，流动絮乱程度增强，换热工质内部物质交换剧烈；与此同时，絮乱程度的提高，极大程度较薄热量交换的边界层厚度，使得热阻进一步减小，两方面的结合，有效的提高了传热效果。The equivalent diameter of the first conductive flow path 31a gradually decreases from its head end 311a to its tail end 312a. This arrangement makes the first conductive flow path 31a formed at both ends of the condensing end 1a and the evaporating end 2a. The channel structure with gradual equivalent diameter increases the flow rate of the liquid heat exchange working fluid at the condensing end 1a, increases the degree of flow flocculation, and the exchange of substances inside the heat exchange working medium is intense; at the same time, the degree of flocculation increases to a great extent. The thinner heat exchange boundary layer thickness further reduces the thermal resistance. The combination of the two aspects effectively improves the heat transfer effect.
更优的，本实施方式中，多条所述冷凝流道11a均匀排布；由所述蒸发进口端201a向所述蒸发出口端202a的方向（换热工质流动的方向），多条所述蒸发流道21a的当量直径依次增大。同一条所述蒸发流道21a的当量直径为定值。More preferably, in this embodiment, a plurality of the condensation flow channels 11a are evenly arranged; from the evaporation inlet end 201a to the evaporation outlet end 202a (the direction in which the heat exchange medium flows), a plurality of The equivalent diameter of the evaporation channel 21a increases in order. The equivalent diameter of the same evaporation channel 21a is a fixed value.
需要说明的是，同一条所述蒸发流道21a的当量直径也可以沿蒸发流道单元20a的蒸发进口端201a向所述蒸发出口端202a的方向（换热工质流动的方向）依次增大，这也是可行的。It should be noted that the equivalent diameter of the same evaporation channel 21a may also increase in the direction from the evaporation inlet end 201a of the evaporation channel unit 20a to the evaporation outlet end 202a (the direction in which the heat exchange medium flows). , This is also feasible.
该结构设置中，因冷凝端1a的气态换热工质均匀的在冷凝流道11a中等压分散，因此，冷凝流道11a均匀铺展设置，在与外界空气进行热量交换过程中较均匀，散热效果稳定。In this structural arrangement, because the gaseous heat exchange working medium of the condensation end 1a is uniformly dispersed in the condensation flow passage 11a at an intermediate pressure, the condensation flow passage 11a is evenly spread and arranged, and the heat exchange process with the outside air is more uniform, and the heat dissipation effect stable.
而蒸发端2a则不同，换热工质由冷凝端1a液化后经所述第一传导流道流回至所述蒸发端2a时，蒸发进口端201a处的当量直径较冷凝出口端112a讯速减小，此时，液态的换热工质流速提升，流动絮乱程度增强，换热工质内部物质交换剧烈；与此同时，絮乱程度的提高，极大程度较薄热量交换的边界层厚度，使得热阻进一步减小，两方面的结合，有效的提高了传热效果。同时，蒸发流道21a的上述结构设计可在换热工质蒸发为气体时，为其提供膨胀空间，使得换热工质流速均匀，压力平均，与热源的热交换更快更稳定。The evaporation end 2a is different. When the heat exchange working fluid is liquefied from the condensation end 1a and then flows back to the evaporation end 2a through the first conductive flow path, the equivalent diameter at the evaporation inlet end 201a is faster than the condensation outlet end 112a. Decrease, at this time, the flow rate of the liquid heat exchange medium increases, the degree of flow flocculation increases, and the material exchange inside the heat exchange medium is intense; at the same time, the degree of flocculation increases, and the boundary layer of heat exchange is greatly thinner The thickness further reduces the thermal resistance, and the combination of the two aspects effectively improves the heat transfer effect. At the same time, the above-mentioned structural design of the evaporation flow channel 21a can provide expansion space for the heat exchange working medium when it evaporates into a gas, so that the heat exchange working medium has a uniform flow rate and an even pressure, and the heat exchange with the heat source is faster and more stable.
本实施方式中，所述第一传导流道31a的尾端312a的当量直径和与其尾端312a连通的所述蒸发流道21a的当量直径相同，或至少不于大和与其尾端312a连通的所述蒸发流道21a的当量直径，以避免增加换热工质的流动阻力，改善传递效果。In this embodiment, the equivalent diameter of the tail end 312a of the first conductive flow passage 31a is the same as the equivalent diameter of the evaporation flow passage 21a connected to the tail end 312a, or at least not smaller than that of Yamato and its tail end 312a. The equivalent diameter of the evaporation channel 21a is to avoid increasing the flow resistance of the heat exchange working fluid and improve the transfer effect.
