Referring to fig. 1, an exploded view of a housing assembly 100 according to a preferred embodiment of the invention is shown. In this embodiment, the housing assembly 100 includes a housing body 110, the housing body 110 may be sleeved outside the smart terminal 200, and partially or completely cover the back shell, the side edge, and other portions of the smart terminal 200, and basically attach to the smart terminal 200, so as to be used as a protective cover for the smart terminal 200, and also used as a handheld portion for assisting a user to handle and enhancing a handheld experience. In this embodiment, in order to improve the heat dissipation efficiency of the heat generated by the smart terminal 200, the housing assembly 100 further includes:
The thermoelectric cooling plate 120, which may also be referred to as a semiconductor cooling plate or peltier device, uses the peltier effect to generate a phenomenon that one side is cooled and the other side is heated when different conductors are energized. To help the smart terminal 200 dissipate heat, the thermoelectric cooling fins 120 are disposed inside the case body 110 and transfer heat with the heat source of the smart terminal 200. Specifically, the heat source of the smart terminal 200 may be a processor, a battery, a graphic processing module, etc., which operate at a high load. Thermoelectric refrigeration piece 120 circular telegram back will form cold junction and hot junction, cold junction and heat source heat transfer, like the indirect heat conduction of pressing from both sides the material between direct contact's heat conduction, cold junction and heat source, the heat radiation mode that cold junction and heat source clearance set up (be close to but not contact), with the heat transfer that produces on the heat source to the cold junction on. Therefore, as long as the thermoelectric cooling plate 120 is in an operating state, it will absorb heat from the heat source, and help the heat source of the smart terminal 200 to cool down.
-a power supply 130
In order to make the thermoelectric cooling plate 120 work normally, a power supply 130 is further included in the housing body 110, completely covered by the housing body 110, and electrically connected to the thermoelectric cooling plate 120, when the power supply 130 is activated, power is supplied to the thermoelectric cooling plate 120, so as to drive the thermoelectric cooling plate 120 to work.
A fan module 150
Except that the heat absorption and cooling of the intelligent terminal 200 are performed by the thermoelectric cooling plate 120 in the housing assembly 100, the heat radiation process from the heat to the outside of the housing assembly 100 is accelerated by the combined use of the fan module 150. Specifically. The fan module 150 is also disposed in the housing body 110 and located on a side of the thermoelectric cooling plate 120 away from the smart terminal 200. That is, after the heat source of the smart terminal 200 generates heat, the heat is still transferred to the cold end of the thermoelectric cooling plate 120 first, and then transferred from the cold end to the hot end of the thermoelectric cooling plate 120. Therefore, the fan module 150 is disposed close to the hot end, when the fan module 150 is started, the rotation of the fan in the fan module 150 will bring the effect of sucking the air at the hot end, i.e. the fan sucks the air around the hot end, so as to improve the convection effect of the air around the hot end and improve the heat dissipation capability. Meanwhile, the sucked air, such as hot air, is then discharged out of the case body 110 by the fan. Through the arrangement of the fan module 150, the heat absorbed originally from the heat source is quickly discharged out of the housing body 110 after being transferred to the hot end, and when the heat at the hot end is taken out, the temperature of the heat is reduced, so that the heat absorption capacity of the hot end from the cold end can be further accelerated, and the heat absorption capacity of the cold end from the heat source is reversely improved. Through the process of accelerating the whole heat transfer, the heat dissipation efficiency of the intelligent terminal 200 is improved.
After the configuration is adopted, the power supply 130 is activated to supply power to the thermoelectric refrigerating fins 120, so that the thermoelectric refrigerating fins 120 are switched to be in a state with a cold end and a hot end, after the cold end absorbs heat generated by the heat source, the heat is conducted to the hot end again, and after the hot end dissipates the heat, the heat dissipation process from the heat source-the cold end-the hot end-the fan module-the outside is realized.
Through the setting of thermoelectric refrigeration piece 120, combine the design of fan module 150, can strengthen the radiating effect by a wide margin. In addition, due to the design of the thermoelectric cooling plate 120, the heat transfer efficiency of the thermoelectric cooling plate in direct contact or indirect contact with the heat source is much higher than the heat convection efficiency when a fan is used alone. Therefore, when the heat source of intelligent terminal 200 produced heat, very first time will be conducted to the cold junction fast, and rethread fan module 150 conducts to the outside of casing assembly 100, can increase substantially the radiating effect.
The housing assembly 100 further includes:
a switching element 140
Once the power supply 130 is activated, the thermoelectric cooling fins 120 are driven to operate. To conserve power in the power supply 130, the power supply 130 is controlled to be activated when needed. The casing body 110 is further provided with a switch element 140, a portion of the switch element 140 is electrically connected to the power source 130, and another portion is exposed out of the casing body 110 for operation by a user. For example, when the user performs pressing, voice manipulation, sliding, touching, toggling and other operations on the switch element 140, the switch element 140 is switched to be in the on state or the off state, and when the switch element 140 is in the on state, the power supply 130 is activated, and the electric energy is transmitted from the power supply 130 to the thermoelectric cooling fins 120; when the switching element 140 is in the off state, the power transmission path of the power supply 130 is disconnected, the thermoelectric cooling plate 120 does not work any more, and the heat dissipation of the heat source of the smart terminal 200 is stopped.
Through the setting of the switch element 140, a user can freely control whether the forced cooling function needs to be started, the thermoelectric cooling sheet 120 is utilized to dissipate heat of a heat source, the electric energy is saved, meanwhile, an element for freely controlling the switch of the heat dissipation function can be provided for the user, and the autonomy of user operation is improved.
Further preferably, the switch element 140 is a broken line type, and includes a first end 141, a second end 142, and a connecting portion 143 connected to the first end 141 and the second end 142. The first terminal 141 is in disconnectable contact with the power source 130, i.e. when the first terminal 141 is in contact with the power source 130, the power supply circuit inside the power source 130 is turned on, whereas when the first terminal 141 is separated from the power source 130, the power supply circuit inside the power source 130 is turned off. The connecting portion 143 extends from the first end 141 until partially exposed out of the housing body 110, and the extending direction may be toward a side of the housing body 110 close to the first end 141 or a side of the housing body 110 far from the first end 141. The extended stop position of the connecting portion 143 is formed as a second end 142, and the second end 142 receives various forces, such as pressing force, friction force of sliding operation, elastic force of toggle operation, etc., applied by the user to the operation by extending out of the housing body 110. When the second end 142 is operated, the connecting portion 143 is moved, and the connecting portion 143 further drives the first end 141 to contact the power source 130, so as to turn on or off the power supply of the power source 130 to the thermoelectric cooling plate 120.
Considering that the housing assembly 100 is used to house the smart terminal 200, an interface for connecting a charging cable, an earphone cable, and the like is generally provided on the smart terminal 200. Therefore, when the housing assembly 100 is sleeved outside the intelligent terminal 200, the housing assembly 100 further includes an interface male end and an interface female end, the interface male end is disposed in the housing body 110, the interface type of the interface male end can be the same as that of the intelligent terminal 200, and the interface male end can be inserted into the socket of the intelligent terminal 200, so as to transfer the position of the socket of the intelligent terminal 200 to the interface female end. Therefore, the interface female end is electrically connected with the interface male end, and the interface female end replaces a socket of the intelligent terminal 200 to receive an external charging wire and an earphone wire. It can be understood that, the position of the female terminal of the interface can be set according to the needs of the user, for example, set up on the side of the housing body 110, when the user puts the smart terminal 200 horizontally, the connecting wire inserted into the female terminal of the interface will be isolated from the hand when the user holds the smart terminal 200, which improves the user experience.
Further preferably, there may be a plurality of interface female terminals, all of which are electrically connected with the interface male terminal. And the type of the female end of the interface can be Micro USB, USB type-c, lighting and the like, so that electric connecting wires of different interface types can be used.
In order to control the thickness of the housing assembly 100 and reduce the degree of hand movement of a user when holding the housing assembly 100 as much as possible, the thermoelectric cooling fins 120 and the power supply 130 are arranged in a flat manner, that is, the thermoelectric cooling fins 120 and the power supply 130 are arranged on the same end face of the intelligent terminal 200, and the power supply 130 does not block the absorption and dissipation of heat in the projection direction of the thermoelectric cooling fins 120, that is, above or below the thermoelectric cooling fins. The placement position of the power supply 130 is located on the side, above the side, or below the side of the thermoelectric cooling fins 120, so as to ensure the heat dissipation effect of the thermoelectric cooling fins 120 as much as possible, and at the same time, improve the space utilization rate and reduce the thickness of the housing assembly 100.
In another preferred or optional embodiment, the housing assembly 100 further comprises:
in a further preferred embodiment, in order to discharge all the heat absorbed by the fan module 150 from the hot end to the outside of the housing body 110, and not feed back to the intelligent terminal 200, an opening is disposed on an end surface of the housing body 110 away from the intelligent terminal 200, and the opening can also be used as an air outlet 153 of the fan module 150, so that the heat absorbed by the fan module 150 when the fan rotates will pass through the housing body 110 from the opening to the outside of the housing assembly 100, thereby ensuring the heat dissipation efficiency of the whole heat transfer process. It can be understood that the user usually uses the housing assembly 100 by holding it from both short sides, and therefore, the opening can be disposed in the middle of the housing body 110, so that the dissipated heat will not be directly opposite to the user's hand, thereby improving the user experience.
Further preferably, a control element is further included in the housing assembly 100, and is electrically connected to the fan module 150, and is partially exposed from the housing assembly 100, so as to facilitate operation by a user. When the user operates the control device, the fan module 150 can be controlled to be in an on state or an off state. It is understood that the control element and the switch element 140 may be integrated into the same component, or may be separately set up, that is, the user can simultaneously control the switch of the power source 130 and the fan module 150 by operating one component, that is, simultaneously turn off or start the operation of the thermoelectric cooling fins 120 and the fan module 150. Or, the control element and the switch element 140 may be set separately according to the user's requirement, and the user independently turns on or off the thermoelectric cooling plate 120 and the fan module 150 according to the user's requirement, so as to freely control the heat dissipation effect.
The fan module 150 may further include a module holder 151 and a fan element 152, wherein the module holder 151 is fixed to the housing body 110, for example, by welding or nailing, and is fixed to a mounting surface of the housing body 110. The fan member 152 is disposed in the module holder 151, and a cavity communicating with an external space is formed in the module holder 151, and the thickness of the cavity may be similar to that of the fan member 152. When the fan element 152 is disposed in the module holder 151, the fan element 152 cannot move in the cavity, and the displacement of the fan element 152 is limited by the module holder 151, so that the position of the fan element 152 is fixed and the direction of dissipating heat is also fixed.
In a preferred embodiment, the housing assembly 100 further comprises:
a heat conducting element 160
A heat conducting element 160 may be further disposed between the smart terminal 200 and the thermoelectric cooling plate 120. The heat conducting element 160 is made of a material that easily conducts heat, and may be directly attached to the smart terminal 200 and/or the thermoelectric cooling plate 120 during installation, or attached to the smart terminal and/or the thermoelectric cooling plate by using a heat conducting foam or a heat conducting silicone pad. The heat conducting element 160 is arranged to accelerate the speed of discharging the heat generated by the heat source of the smart terminal 200 out of the smart terminal 200, and the heat is conducted to the thermoelectric cooling plate 120 more quickly by guiding the heat, so that the heat is dissipated by the thermoelectric cooling plate.
It can be understood that the area of the heat conducting element 160 can be set to be larger, on one hand, the contact area with the smart terminal 200 is increased, so that the heat dissipation effect is improved, and on the other hand, the thermoelectric cooling plate 120 is separated from the smart terminal 200, so that the damage of the supercooling of the thermoelectric cooling plate 120 to the housing of the smart terminal 200 is prevented.
Preferably or optionally, the housing assembly 100 further comprises:
-a heat-dissipating element 170
A heat dissipation element 170 may be further disposed on an end surface of the thermoelectric cooling plate 120 facing to the outside, i.e., an end surface far away from the smart terminal 200. The heat dissipation element 170 is made of a material that easily dissipates heat, and may be directly attached to the thermoelectric cooling plate 120 during installation, and is attached to the thermoelectric cooling plate 120 by using a heat-conductive foam or a heat-conductive silica gel pad. The heat dissipation element 170 is arranged to increase the heat dissipation rate of the hot side of the thermoelectric cooling plate 120. It can be understood that, since the two sides of the thermoelectric cooling plate 120 are energy-conserving, if the heat absorption capacity of the cold end cannot be dissipated in time, the heat absorption capacity will be broken, and the whole heat dissipation capacity of the thermoelectric cooling plate 120 cannot be exerted. By guiding the heat, the heat is more rapidly conducted to the outside of the thermoelectric cooling plate 120, and the heat dissipation efficiency is improved.
It can be understood that the area of the heat dissipation element 170 can be set to be larger, on one hand, the heat dissipation effect is improved by increasing the contact area with the hot end of the thermoelectric cooling plate 120, and on the other hand, the heat dissipation area is enlarged by increasing the area of the heat dissipation element, so that the heat dissipation effect is further improved.
A circuit board assembly 180 may be further disposed beside the heat dissipation element 170 or the thermoelectric cooling plate 120 for connecting the thermoelectric cooling plate 120 and the power source 130 to intelligently control the on/off or cooling effect of the thermoelectric cooling plate 120. For example, a processing element such as a chip may be disposed on the circuit board assembly 180, and the magnitude of the current provided by the power supply 130 to the thermoelectric cooling fins 120 is controlled, so as to control the temperature difference between the upper cold end and the hot end of the thermoelectric cooling fins 120, thereby facilitating the adjustment of the heat dissipation effect of the user under different temperature conditions, for example, when the heat source of the intelligent terminal 200 generates less heat, the power saving mode may be adopted to control the thermoelectric cooling fins 120 to dissipate heat slightly; if the heat source of the intelligent terminal 200 generates more heat, the performance mode can be adopted to control the thermoelectric cooling point 120 to increase the heat dissipation, so as to further improve the use experience of the user.
In another preferred embodiment, the power supply in the housing assembly is connected to the interface female terminal through the integrated circuit, that is, two power supply circuits are provided outside the power supply to supply power to the thermoelectric cooling plate and the interface female terminal, respectively. Along with the electric connection between the interface female end and the interface male end, the interface male end is inserted into the socket of the intelligent terminal after the shell body is sleeved outside the intelligent terminal, namely, the power supply also supplies power to the socket of the intelligent terminal. Because this interface is connected with intelligent terminal's battery through integrated mode, consequently, when shell body cover was established outside intelligent terminal, integrated circuit, interface female end, interface male end, interface, charging circuit formed a charging path, transmitted the electric energy of casing assembly's power to intelligent terminal's battery, that is to say the casing assembly not only can be used as the heat dissipation to intelligent terminal, also can be used as portable power source to intelligent terminal reverse charging ability. Furthermore, a charging and discharging module can be arranged on the integrated circuit, when the interface female end of the shell assembly is externally connected with a mains supply, the mains supply charges the power supply and provides working electric energy for the fan module and the thermoelectric refrigerating sheet.
Referring to fig. 2, when the housing assembly 100 of any of the above embodiments is provided, it is covered outside an intelligent terminal 200, for example, the housing assembly is covered on a back shell of the intelligent terminal 200 and is used as a protective sleeve and a heat dissipation sleeve, or is directly integrated with the back shell of the intelligent terminal 200 during a manufacturing process of the intelligent terminal 200. When a user finds that the temperature of the heat source of the intelligent terminal 200 is high when using the intelligent terminal 200, the switch element 140 or the control element can be operated to control the thermoelectric cooling sheet 120 or the fan module 150 to work, so that heat is strongly dissipated to the intelligent terminal 200, and the noise generated by the fan can be further reduced by reducing the use of the original fan, thereby achieving heat dissipation in a mute state.
The smart terminal may be implemented in various forms.
