The wearable device provided in the embodiment of the application can be a smart phone, a tablet, a notebook computer or other devices with a card slot structure or external part stretching requirements.
A dial plate structure and a wearable device provided according to an embodiment of the present application are described below with reference to fig. 1 to 13.
As shown in fig. 1 and 2, one embodiment of the present application proposes a dial plate structure 100 including: the air conditioner comprises a shell 102, wherein an air inlet 1022 and an air outlet 1024 are respectively arranged on two sides of the shell 102; at least one heat dissipation air duct 104 disposed in the housing 102, wherein two ends of the heat dissipation air duct 104 are respectively communicated with the air inlet 1022 and the air outlet 1024; the ion wind power electrode groups 106 are arranged in the heat dissipation air duct 104; the temperature equalizing plate 108 is disposed in the housing 102, and the temperature equalizing plate 108 and the heat dissipating air duct 104 are stacked.
According to the embodiment of the dial plate structure 100 provided by the application, the dial plate structure mainly comprises a casing 102, a heat dissipation air duct 104 arranged in the casing 102, an ion wind power electrode group 106 for heat dissipation and a temperature equalizing plate 108, wherein the casing 102 is mainly used for fixing the positions of internal electrical components, and meanwhile, due to the fact that other structures are arranged in the casing 102, the casing 102 can also play a certain protection role. The heat generated in the housing 102 during use is mainly realized by the heat dissipation air duct 104, the ion wind power electrode set 106 and the temperature equalization plate 108. Specifically, an air inlet 1022 and an air outlet 1024 are disposed on two sides of the housing 102, and two ends of the heat dissipation air duct 104 are respectively connected to the air inlet 1022 and the air outlet 1024, so as to implement a flow path of air, and by disposing the air inlet 1022 and the air outlet 1024 on two opposite sides of the housing 102, the mutual influence between the air temperature of the air inlet 1022 and the air temperature of the air outlet 1024 is reduced to the greatest extent, and the heat dissipation efficiency is improved. For the air in the heat dissipation air duct 104, the movement of the air is mainly the ion wind generated by the ion wind movement when the ion wind power electrode set 106 is running, so as to drive the air of other parts in the heat dissipation air duct 104 to move together, thereby realizing the heat dissipation of the whole shell 102.
The air inlet 1022 and the air outlet 1024 may be disposed on opposite sides of the housing 102, and may be disposed on any different sides of the housing 102.
Further, the number of the heat dissipation air ducts 104 arranged in the casing 102 may be one or multiple, and the heat dissipation air ducts are mainly flexibly arranged according to the space inside the casing 102, but generally, because the overall size of the dial plate structure 100 is not large, the heat dissipation effect can be achieved by arranging one heat dissipation air duct 104.
It will be appreciated that the more ducts, the more cross-sectional area of the duct is occupied, and that although the wind speed is increased, the total wind volume is correspondingly reduced.
It should be emphasized that, since the space inside the casing 102 is generally small, the heat sources are usually disposed at different positions, and the temperature equalizing plate 108 disposed in the casing 102 and stacked with the heat dissipating air duct 104 can continuously conduct the heat generated by the different heat sources to the heat dissipating air duct 104, so that the air flows to bring the heat out of the dial plate structure 100.
Furthermore, the temperature equalizing plate 108 and the heat dissipation air duct 104 are stacked, and the two components are in surface contact, so that the heat conduction effect can be greatly improved.
As shown in fig. 4, for the type of the temperature equalizing plate 108, a phase-change temperature equalizing plate 108 can be selected, and the purpose of effective heat transfer is achieved by absorbing and releasing latent heat through the phase-change process of the working medium. It is understood that the vapor chamber 108 conducts heat over a two-dimensional surface.
Specifically, as for the heat dissipation air duct 104, a material with high insulation property may be used, and in consideration of its shape, an insulating ceramic or a plastic with high insulation property may be used; the air duct forms a closed duct between the air inlet 1022 and the air outlet 1024, and in addition, part of the air duct profile is a converging-diverging laval nozzle profile to reduce wind resistance and improve wind speed.
When the temperature equalization plate 108 performs temperature equalization treatment, the liquid at the bottom of the vacuum chamber absorbs the heat of the structure at the other side of the temperature equalization plate 108, evaporates and diffuses into the vacuum chamber, conducts the heat to the radiating fins, condenses into liquid, and returns to the bottom. The vapor and the condensate are quickly circulated in the vacuum chamber, so that higher temperature equalizing efficiency is realized.
Further, as shown in fig. 9 and 11, the heat dissipation air duct 104 specifically includes: the air inlet section 1042 is connected with the air inlet 1022; an air outlet section 1048 connected to the air outlet 1024; a transition section 1044, two ends of the transition section 1044 are respectively connected with the air inlet section 1042 and the air outlet section 1048; the sizes of the air inlet openings 118 connected to the air inlet section 1042 and the air outlet openings 120 connected to the air outlet section 1048 are different.
Specifically, as shown in fig. 9, in the present embodiment, the width of the air inlet opening 118 of the transition section 1044 connected to the air inlet section 1042 is greater than the width of the air outlet opening 120 of the transition section 1044 connected to the air outlet section 1048.
As shown in fig. 11, in another embodiment, the width of the air inlet opening 118 of the transition section 1044 connected to the air inlet section 1042 is smaller than the width of the air outlet opening 120 of the transition section 1044 connected to the air outlet section 1048.
The heat dissipation duct 104 mainly includes three pipe sections, which are an air inlet section 1042, an air outlet section 1048, and a transition section 1044 connected therebetween, wherein the air inlet section 1042 is connected with the air inlet 1022, and air flowing in through the air inlet 1022 will firstly pass through the air inlet section 1042 and then pass through the transition section 1044 and then be discharged to the air outlet 1024 from the air outlet section 1048, thereby realizing air-cooling heat dissipation. It is emphasized that the air flowing into the transition section 1044 has a variation in the flow velocity due to the difference in the opening size of the two end faces of the transition section 1044.
Further, as shown in fig. 10 and 12, the transition section 1044 includes a converging section 1045 and a diverging section 1046 connected in a direction from the intake opening 1022 to the outtake 1024. The opening width of the end of the closing-in section 1045 close to the air inlet section 1042 is greater than the opening width of the end of the closing-in section 1045 close to the air outlet section 1048. The opening width of the end of the flared section 1046 close to the air outlet section 1048 is greater than the opening width of the end of the flared section 1046 close to the air inlet section 1042.
Further, as shown in fig. 10, the opening width of the end of the closing-in section 1045 close to the air inlet section 1042 is greater than the opening width of the end of the flaring section 1046 close to the air outlet section 1048.
Further, as shown in fig. 12, the opening width of the end of the closing-in section 1045 close to the air inlet section 1042 is smaller than the opening width of the end of the flaring section 1046 close to the air outlet section 1048.
In this embodiment, one end of the closing-in section 1045 close to the air inlet section 1042 is directly connected to the air inlet section 1042. The end of the closing-in section 1045 close to the air outlet section 1048 is directly connected to the end of the flaring section 1046 close to the air inlet section 1042. One end of the flared section 1046 close to the air outlet section 1048 is directly connected to the air outlet section 1048.
For the changeover portion 1044, the trompil size of two terminal surfaces is inequality, on this basis, restrict the changeover portion 1044 including binding off section 1045 and flaring section 1046 simultaneously, the air can pass through air inlet section 1042 in proper order when flowing, binding off section 1045, flaring section 1046 and air-out section 1048, under this structure, through setting up the ion wind-powered generator group in the latter half of radiating duct 104, also flaring section 1046 and air-out section 1048 play, no matter what the flow velocity of the ion wind of ionization is, can all play positive effect. Specifically, if the air velocity is greater than mach 1, it will be favorable to reducing the gas resistance under the effect of transition section 1044, promote the air velocity, and if the air velocity is less than mach 1, help the air current to accelerate under the effect of transition section 1044 to promote the heat that the module took away in the unit interval.
It is emphasized that the opening area of the end of the closing section 1045 connected to the air inlet section 1042 is larger than the opening area of the end connected to the flared section 1046, and the opening area of the end of the flared section 1046 connected to the air outlet section 1048 is also larger than the opening area connected to the closing section 1045, so that the tube diameter of the air is reduced and then increased no matter which direction the air flows from, thereby increasing the air flow velocity.
Still further, the variation in cross-sectional area defining the transition section 1044 is the same as for a laval nozzle configuration.
The width of the air inlet opening of the transition section 1044 is greater than that of the air outlet opening, the ion wind electrode set 106 is arranged on the flaring section 1046 and the air outlet section 1048, and the heat dissipation efficiency is good.
In a specific embodiment, the ion wind power electrode set 106 is arranged in the whole heat dissipation air duct except for the area where the heat radiator is located, and in the air inlet section, the air outlet section and the transition section.
In another specific embodiment, the ion wind electrode set 106 is disposed at the air inlet section, and ions generated by the ion wind electrodes are coupled to generate positive pressure to blow air to the heat sink by blowing air.
Further, the size of the opening of the two end faces of the transition section is different, specifically, the opening area is different. Further, when the area of the air inlet opening is large and the area of the air outlet opening is small, the heat dissipation effect is good.
Further, the temperature-uniforming plate covers the heat dissipation air duct, and the dial structure still includes: the radiator 110 is arranged in the radiating air duct 104, and the radiator 110 is connected with the temperature-equalizing plate 108; wherein, the radiator 110 is arranged at the air outlet section.
By arranging the heat sink 110 inside the heat dissipation air duct 104 and arranging the heat sink 110 on the other side of the temperature equalizing plate 108, the heat on the temperature equalizing plate 108 can be conducted to the heat dissipation air duct under the action of the heat sink 110 because the temperature equalizing plate covers the heat dissipation air duct, so that the heat in the heat dissipation air duct 104 can be discharged through the air outlet 1024.
It should be noted that, by limiting the size of the temperature equalizing plate 108 to be larger and the temperature equalizing plate to cover the heat dissipating air duct, it can be understood that the plane where the temperature equalizing plate 108 is located is taken as a projection plane, and the temperature equalizing plate 108 is limited to completely cover the orthographic projection of the heat dissipating air duct 104 on the projection plane, so as to improve the heat equalizing effect of the temperature equalizing plate 108 on a large number of heat generating pieces, especially the heat generating pieces located at the bottom of the temperature equalizing plate 108, and by using the temperature equalizing plate 108 with a larger area, the heat equalizing speed can be improved, so that when the local heat is too high, the local heat can be quickly transferred to other areas, and when heat is dissipated, the heat of other high-temperature areas can be transferred to the heat dissipating area after the temperature of part of the heat sink 110 is reduced, thereby realizing continuous heat dissipation.
The heat sink 110 may be directly welded to the vapor chamber 108, or directly bonded to the vapor chamber 108 through a double-sided adhesive tape having a certain thermal conductivity.
Further, as shown in fig. 5, 7 and 8, the number of the ion wind electrode groups 106 is plural, and each ion wind electrode group 106 includes: the positive grid 1062 and the negative grid 1064 are arranged at intervals, one side of the positive grid 1062, which faces the negative grid 1064, is provided with a plurality of ionization needles 1063 arranged in an array, wherein the plane of the positive grid is parallel to the cross section of the heat dissipation air duct, the plane of the negative grid is parallel to the cross section of the heat dissipation air duct, and the ion wind power electrode group enables outside air to flow into the heat dissipation air duct from the air inlet and then to be discharged from the air outlet.
As shown in fig. 7 and 8, the ion wind power electrode group 106 mainly includes a positive grid 1062 and a negative grid 1064 which are arranged at intervals, and when a high voltage is applied, a high voltage electric field is formed between the two grids to ionize air between the two grids, so as to form positive ions and negative ions, wherein the positive ions are located at the positive grid 1062, and the negative ions are located at the negative grid 1064, at this time, due to the high voltage electric field between the two grids, the positive ions are located at the ionizing pins 1063 and continuously approach the negative ions on the negative grid 1064, and in the moving process, other non-ionized gases are driven to move together, so as to form an ion wind.
The direction from the air inlet 1022 to the air outlet 1024 along the heat dissipation duct 1044 is defined as the air flowing direction. The angle between the plane of the positive grid 1062 and the direction of air flow is greater than 75 °. The negative grid 1064 is at an angle greater than 75 ° to the direction of air flow. The ion wind power electrode set 106 enables outside air to flow into the heat dissipation air duct from the air inlet 1022 and then to be discharged from the air outlet 1024.
Optionally, the positive electrode grid and the negative electrode grid are arranged perpendicular to the air flowing direction in the heat dissipation air duct, that is, the plane where the two grids are located and the cross section perpendicular to the air flowing direction in the heat dissipation air duct are arranged in parallel, so that the air volume of the ion air can be improved to the greatest extent, and the heat dissipation effect is improved.
In order to generate positive ions and negative ions on the positive grid 1062 and the negative grid 1064, a voltage transformation device 112 capable of generating a high voltage is required to ionize air and further realize an ion wind.
Furthermore, at least part of the heat dissipation air duct is positioned outside the temperature-equalizing plate in the orthographic projection of the plane where the temperature-equalizing plate is positioned.
In this scheme, partial heat dissipation wind channel is not covered by the temperature-uniforming plate, because the volume of temperature-uniforming plate receives the volume restriction of whole casing. At the moment, the heat emitted by the parts with remote positions can directly enter the heat dissipation air duct under the conduction of the heat dissipation air duct, the temperature equalizing plate does not need to extend to the position of the part, the requirement on the shape of the temperature equalizing plate is low, and therefore the production and installation efficiency is improved.
Further, as shown in fig. 3, the housing 102 specifically includes: the middle frame 1026, the air inlet 1022 and the air outlet 1024 are arranged on two opposite sides of the middle frame 1026; a bottom cover 1028 disposed at one end of the middle frame 1026; the display screen 1030 is arranged at the other end of the middle frame 1026, the bottom cover 1028 and the display screen 1030 surround to form an accommodating cavity, and the heat dissipation air duct 104 is arranged in the accommodating cavity.
For the case 102, the case mainly includes a middle frame 1026, and a bottom cover 1028 and a display screen 1030 respectively disposed at two ends of the middle frame 1026, where for the general dial structure 100, the bottom cover 1028 is a portion contacting with a human body and may be an inner side, and the display screen 1030 is located at an outer side to display different interface contents. Can form hollow chamber that holds after linking to each other through the restriction three to with the setting of radiating air duct 104 holding the intracavity, under a plurality of combined action, can effectually utilize the forced air cooling to distribute away the heat of inside, experience with the use when guaranteeing the user and dress.
Further, the air inlet 1022 and the air outlet 1024 are disposed on opposite sides of the housing, and the heat dissipation duct 104 is disposed in the accommodating cavity along a straight line from the air inlet 1022 to the air outlet 1024.
By limiting the heat dissipation air duct 104 to be directly disposed along the opposite sides of the housing 102, the air duct structure occupies a smaller space, and a better heat dissipation effect can be achieved by using the smaller space.
It can be understood that the extending direction of the heat dissipation air duct 104 is a straight line, the length of the heat dissipation air duct 104 is small, the kinetic energy loss of the air in the heat dissipation air duct 104 is relatively reduced, and the normal heat dissipation air volume can be ensured.
Further, as shown in fig. 3, the method further includes: the mainboard 1032 is stacked with the temperature-equalizing plate and the heat dissipation air duct and is arranged in the accommodating cavity, wherein the temperature-equalizing plate is arranged between the mainboard and the heat dissipation air duct, and the orthographic projection of the heat dissipation air duct on the plane where the temperature-equalizing plate is located in the temperature-equalizing plate.
Through holding the intracavity setting and the mainboard 1032 that the temperature equalization board 108 and the stack-up setting of heat dissipation wind channel to set up the temperature equalization board between mainboard and heat dissipation wind channel, the opposite side of temperature equalization board 108 is provided with heat dissipation wind channel 104 and radiator 110 promptly, and the heat that mainboard 1032 gived off can advance the temperature equalization board and carry out the samming and handle this moment, reduces the overheated possibility of local temperature, and then outside the discharge of rethread heat dissipation wind channel.
It should be emphasized that, by limiting the orthographic projection of the heat dissipation air duct on the temperature equalization plate 108 to be located in the temperature equalization plate 108, it is ensured that the heat generated by the main board can be completely received by the temperature equalization plate 108, and thus, the heat is conducted into the heat dissipation air duct for being discharged.
