Referring to FIG. 1, it is a schematic exploded view of the housing assembly 100 according to a preferred embodiment of the present invention. In this embodiment, the housing assembly 100 includes a housing body 110, which can be sleeved on the outside of the smart terminal 200, and partially or completely covers the back shell and sides of the smart terminal 200. The terminal 200 is fit, that is, used as a protective cover of the smart terminal 200, and can also be used as a hand-held part that helps a user to hold it and enhance the hand-held experience. In this embodiment, to improve the heat dissipation efficiency of the heat generated by the smart terminal 200, the housing assembly 100 further includes:

-Thermoelectric cooling sheet 120

The thermoelectric cooling plate 120, which may also be called a semiconductor cooling plate, Peltier, utilizes the Peltier effect to generate a phenomenon of cooling on one side and heating on different conductors when energized. To help the smart terminal 200 dissipate heat, in this embodiment, the thermoelectric cooling sheet 120 is used as the base, which is disposed in the housing body 110 and transfers 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 graphics processing module, and the like that run at high load. When the thermoelectric cooling plate 120 is energized, it will form a cold end and a hot end. The heat transfer between the cold end and the heat source, such as direct contact heat conduction, indirect heat conduction between the cold end and the heat source, the gap between the cold end and the heat source (close but not The heat radiation method of contact) transfers the heat generated from the heat source to the cold end. Therefore, as long as the thermoelectric cooling sheet 120 is in the working state, it will absorb the heat from the heat source and help the heat source of the smart terminal 200 to cool down.

-Power 130

In order to make the thermoelectric cooling plate 120 work normally, a power supply 130 is also included in the housing body 110, which is completely covered by the housing body 110 and electrically connected to the thermoelectric cooling plate 120. When the power supply 130 is activated, the thermoelectric cooling plate 120 Power is supplied to drive the thermoelectric cooling sheet 120 to work.

-Fan module 150

In addition to using the thermoelectric cooling sheet 120 in the housing assembly 100 to absorb heat and cool the smart terminal 200, a fan module 150 will also be used in combination to accelerate the heat radiation process of the heat radiation to the outside of the housing assembly 100. specifically. The fan module 150 is also disposed in the casing body 110 and located on the side of the thermoelectric cooling sheet 120 away from the smart terminal 200. In other words, when the heat source of the smart terminal 200 generates heat, the heat will still be transferred to the cold end of the thermoelectric cooling plate 120 first, and then from the cold end to the hot end of the thermoelectric cooling plate 120, because the heat is concentrated in the hot end If you want to dissipate the heat on the hot end, you need to gradually dissipate the external radiation ability of the hot end. Therefore, the fan module 150 is located close to the hot end. When the fan module 150 is started, the rotation of the fan in the fan module 150 will have an effect of sucking the air at the hot end, that is, the fan sucks the air around the hot end. To improve the convection effect of the air around the hot end and improve the heat dissipation capacity. At the same time, the sucked air, such as hot air, will be discharged to the outside of the housing body 110 by the fan. Through the arrangement of the fan module 150, the heat originally absorbed from the heat source will be quickly discharged out of the housing body 110 after being transferred to the hot end. When the heat at the hot end is taken out, its temperature drops, which can be further accelerated The ability of the hot end to absorb heat from the cold end increases the ability of the cold end to absorb heat from the heat source. By speeding up the entire heat transfer process, the heat dissipation efficiency of the intelligent terminal 200 is improved.

With the above configuration, the power supply 130 is activated to supply power to the thermoelectric cooling sheet 120, thereby switching the thermoelectric cooling sheet 120 to have a cold end and a hot end. After the cold end absorbs the heat generated by the heat source, the heat will be conducted to the hot end again. After the heat end dissipates the heat, the heat dissipation process from the heat source-cold end-hot end-fan module-will be realized.

The arrangement of the thermoelectric cooling sheet 120 and the design of the fan module 150 can greatly enhance the heat dissipation effect. In addition, due to the design of the thermoelectric cooling plate 120, the heat transfer efficiency 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 the smart terminal 200 generates heat, it will be quickly transferred to the cold end at the first time, and then transferred to the outside of the housing assembly 100 through the fan module 150, which can greatly improve the heat dissipation effect.

The housing assembly 100 also includes:

-Switching element 140

Once the power source 130 is activated, the thermoelectric cooling plate 120 will be driven to work. To save power of the power supply 130, the control power supply 130 is activated when necessary. A switch element 140 is also provided in the housing body 110, a part of the switch element 140 is electrically connected to the power supply 130, and another part is exposed to the housing body 110 for user operation. For example, when the user performs operations such as pressing, voice manipulation, sliding, tapping, and toggling on the switching element 140, the switching element 140 is switched on or off. When the switching element 140 is on, the power supply 130 is When activated, power will be transferred from the power supply 130 to the thermoelectric cooling plate 120; when the switching element 140 is in the off state, the power transmission path of the power supply 130 will be disconnected, the thermoelectric cooling plate 120 will no longer work, and stop the smart terminal 200 Heat dissipation.

Through the setting of the switching element 140, the user can freely control whether the strong cooling function needs to be activated, and use the thermoelectric cooling sheet 120 to radiate the heat source to save electrical energy, and at the same time provide the user with a component that can freely control the cooling function switch to improve the user's autonomy of operation .

Further preferably, the switching element 140 has a polyline shape, 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 end 141 and the power supply 130 are disconnectable contact conductive, that is, when the first end 141 is in contact with the power supply 130, the power supply circuit inside the power supply 130 will be turned on, otherwise, when the first end 141 is separated from the power supply 130, the Disconnect the power supply circuit inside the power supply 130. The connecting portion 143 extends from the first end 141 until the housing body 110 is partially exposed. The extending direction may be toward a side of the housing body 110 close to the first end 141 or away from the housing body 110 far from the first end 141 side. The cut-off position where the connecting portion 143 extends is formed as a second end 142. The second end 142 receives various force exerted by the user on its operation by extending out of the housing body 110, such as pressing force, frictional force of sliding operation, and toggle Elasticity of operation, etc. When the second end 142 is operated, the connecting portion 143 is driven to move, and the connecting portion 143 further drives the first end 141 to contact the power supply 130 to turn on or off the power supply to the thermoelectric cooling sheet 120 by the power supply 130.

It is considered that the housing assembly 100 is used to wrap the smart terminal 200, and the smart terminal 200 is usually provided with an interface for connecting a charging cable, an earphone cable, and other devices. Therefore, when the housing assembly 100 is sleeved outside the intelligent terminal 200, the housing assembly 100 further includes an interface male terminal and an interface female terminal. The interface male terminal is provided in the housing body 110, and the interface type of the interface male terminal can be If the interfaces of the terminal 200 are the same, the male end of the interface can be inserted into the jack of the smart terminal 200, and the position of the jack of the smart terminal 200 is transferred to the female end of the interface. Therefore, the interface female terminal is electrically connected to the interface male terminal, and the interface female terminal replaces the socket of the smart terminal 200 to receive the external charging cable and the earphone cable. It can be understood that the position of the interface female terminal can be set according to the needs of the user, for example, on the side of the housing body 110. When the user lays the smart terminal 200 horizontally, the cable inserted into the interface female terminal will be connected with the user holding the smart terminal 200. The hands are separated to improve the user experience.

Further preferably, there may be a plurality of interface female terminals, all of which are electrically connected to the interface male terminal. And the type of the interface female terminal can be Micro USB, USB type-c, lightening, etc., so that the electrical connection wires of different interface types can be used.

In order to control the thickness of the housing assembly 100 and minimize the user's grip when holding the housing assembly 100, the layout of the thermoelectric cooling fins 120 and the power supply 130 adopts a tile type, that is, the thermoelectric cooling fins 120 and the power supply 130 are arranged in the smart On the same end surface of the terminal 200, in the projection direction of the thermoelectric cooling sheet 120, that is, above or below it, the power supply 130 will not block the absorption and dissipation of heat. The position of the power supply 130 is located on the side, upper side, or lower side of the thermoelectric cooling sheet 120, so as to ensure the heat dissipation effect of the thermoelectric cooling sheet 120 as much as possible, and at the same time, improve space utilization and reduce the thickness of the housing assembly 100.

In another preferred or optional embodiment, the housing assembly 100 further includes:

In a further preferred embodiment, in order to expel all the heat absorbed by the fan module 150 from the hot end to the outside of the housing body 110, and no longer feed back to the smart terminal 200, at the end surface of the housing body 110 away from the smart terminal 200, set There is an opening, which can also be used as the air outlet 153 of the fan module 150, then the heat absorbed by the fan in the fan module 150 from the opening will pass through the opening through the housing body 110 to the outside of the housing assembly 100, Ensure the heat dissipation efficiency of the entire heat transfer process. It can be understood that the user's use of the housing assembly 100 is usually held from the short sides of the two sides. Therefore, the position of the opening can be set in the middle of the housing body 110 so that the heat dissipated will not face the user's hand Department to improve the user experience.

Further preferably, the housing assembly 100 further includes a control element, which is electrically connected to the fan module 150 and is partially exposed to the housing assembly 100 for user convenience. When the user operates the control element, the fan module 150 can be controlled to be turned on or off. It can be understood that the control element and the switching element 140 can be integrated into the same component, or set up separately, that is, the user can control the switch of the power supply 130 and the fan module 150 at the same time by operating one component, that is, turning off or starting the thermoelectricity at the same time Whether the cooling plate 120 and the fan module 150 work. The control element and the switching element 140 can also be established separately according to the user's needs. The user can independently turn on or off the thermoelectric cooling sheet 120 and the fan module 150 according to their own needs, and freely control the heat dissipation effect.

The fan module 150 may further include a module bracket 151 and a fan element 152, wherein the module bracket 151 is fixed on the housing body 110, for example, fixed on a mounting surface of the housing body 110 by welding or nailing. The fan element 152 is disposed in the module bracket 151, and a cavity communicating with the external space is provided inside the module bracket 151, and the thickness of the cavity may be similar to the thickness of the fan element 152. When the fan element 152 is disposed in the module bracket 151, the fan element 152 cannot move in the cavity, and the displacement of the fan element 152 is restricted by the module bracket 151, so that the position of the fan element 152 is fixed, and the direction of heat dissipation is also Can be fixed.

In a preferred embodiment, the housing assembly 100 further includes:

-Thermally conductive element 160

Between the smart terminal 200 and the thermoelectric cooling sheet 120, a heat conducting element 160 may also be provided. The heat conducting element 160 is made of a material that is easy to conduct heat, and can be directly attached to the smart terminal 200 and/or the thermoelectric cooling sheet 120 during installation, or can be attached to the aforementioned two using thermally conductive foam or thermally conductive silicone pads. The arrangement of the heat conducting element 160 can accelerate the speed at which the heat generated by the heat source of the smart terminal 200 is discharged out of the smart terminal 200. By guiding the heat, it is more quickly conducted to the thermoelectric cooling plate 120, and 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 larger. On the one hand, by increasing the contact area with the smart terminal 200, the heat dissipation effect is improved. On the other hand, the thermoelectric cooling sheet 120 is separated from the smart terminal 200 to prevent thermoelectricity. The overcooling of the cooling sheet 120 may cause harm to the casing of the smart terminal 200.

The arrangement of the heat dissipation element 170 can accelerate the heat dissipation rate of the hot end of the thermoelectric cooling sheet 120. It is understandable that since the thermoelectric cooling fins 120 are energy-conserving on both sides, if the heat absorption capability of the cold end cannot be dissipated in time, the heat dissipation capability of the thermoelectric cooling fins 120 cannot be fully exerted. By guiding the heat, it is conducted to the outside of the thermoelectric cooling sheet 120 more quickly, and the heat dissipation efficiency is improved.

It can be understood that the area of the heat dissipation element 170 can be set larger. On the one hand, by increasing the contact area with the hot end of the thermoelectric cooling sheet 120, the heat dissipation effect is improved. On the other hand, by increasing its own area, the heat dissipation area is expanded. Further improve the heat dissipation effect.

In yet another preferred embodiment, the power supply in the housing assembly is connected to the interface female terminal through an integrated circuit, that is to say, two power supply circuits are provided outside the power supply to supply power to the thermoelectric cooling plate and the interface female terminal, respectively. With the electrical connection between the interface female end and the interface male end, the interface male end is sheathed outside the intelligent terminal in the housing body, and then inserted into the socket of the intelligent terminal, that is, the power supply also supplies power to the socket of the intelligent terminal. Because the plug-in interface is connected to the battery of the smart terminal in an integrated manner, when the housing body is sheathed outside the smart terminal, the integrated circuit, the interface female terminal, the interface male terminal, the plug-in interface, and the charging circuit form a charging path, which will The electrical energy of the power supply of the housing assembly is transmitted to the battery of the smart terminal, that is to say, the housing assembly can be used not only as a heat sink for the smart terminal, but also as a mobile power supply to charge the smart terminal back. Further, the integrated circuit may also have a charge and discharge module. When the interface female end of the housing assembly is connected to a mains power supply, the mains power supply will charge the power supply and provide the working power of the fan module and the thermoelectric cooling sheet.
