Referring to fig. 3 and fig. 4, in some embodiments, the mobile device photographing and expanding device according to the embodiments of the present utility model further includes a heat dissipation mechanism 7, where the heat dissipation mechanism 7 is disposed inside the housing 1 and electrically connected to the control module 4, and the heat dissipation mechanism 7, the control module 4 and the power supply module 5 are sequentially disposed along a horizontal direction;

In this embodiment, when the mobile device is connected to the present camera expansion apparatus and is in an operating state, particularly when performing a camera-related operation, the mobile device generates heat due to continuous operation of components such as a processor and an image sensor.

Further, by providing a fan as the heat radiation mechanism 7, an air flow passage can be constructed by the air inlet 1021 and the air outlet 1035 on the housing 1 by utilizing the effect of heat convection. External cold air enters from the air inlet 1021, takes away heat when flowing through the heat dissipation mechanism 7, and the air after temperature rise is discharged from the air outlet 1035 to form continuous air circulation so as to accelerate heat dissipation. At the same time, the surface of the heat dissipation mechanism 7 also radiates heat to the surrounding environment, which aids the heat dissipation process and ensures efficient heat transfer from the mobile device to the surrounding environment.

In some embodiments, active heat dissipation control may be performed by setting the switch 10, or the temperature of the mobile device may be monitored in real time by setting a temperature sensor. When the temperature rises to a certain threshold, the heat dissipation mechanism 7 automatically increases the rotation speed of the fan (if a fan exists) or adjusts the working state of other heat dissipation components to enhance the heat dissipation effect, and when the temperature is reduced to be within a safe range, the heat dissipation intensity is correspondingly reduced, so that the heat dissipation effect is ensured, and meanwhile, the energy sources and the noise are saved, which is only illustrative and not limiting.

Meanwhile, damage to electronic elements in the mobile equipment caused by high temperature can be reduced, and the service life of the mobile equipment is effectively prolonged. The long-term high-temperature environment can accelerate battery aging, reduce chip performance and the like, and the active heat dissipation effect of the heat dissipation mechanism 7 can alleviate the problems, reduce equipment maintenance and replacement frequency and improve the overall reliability and durability of the equipment.

With continued reference to fig. 3 and 4, in some embodiments, the heat dissipation mechanism 7 according to the present utility model includes:

The heat dissipation seat 71, one side of the heat dissipation seat 71 facing away from the first surface 101 is concavely provided with a through groove 710;

at least one cooling fan 72 is disposed in the through slot 710, electrically connected to the control module, and disposed between the air inlet 1021 and the air outlet 1035, wherein an air inlet end of the cooling fan 72 is disposed corresponding to the air inlet 1021, and an air outlet end of the cooling fan 72 is disposed corresponding to the air outlet 1035.

In this embodiment, the heat dissipation mechanism 7 proposed in this embodiment mainly operates based on the heat exchange principle, and the heat dissipation fan 72 is a core member that generates an air flow by rotation, promoting rapid heat transfer and dissipation. When the heat radiation fan 72 is started, an air flow passage is formed between the air inlet 1021 and the air outlet 1035.

The air is sucked from the air inlet 1021 by the heat radiation fan 72, flows through the through-groove 710 area of the heat radiation seat 71, and finally is discharged from the air outlet 1035. In some embodiments, the heat sink 71 may be made of a material having good thermal conductivity (e.g., aluminum alloy, etc.), which may absorb heat from a heat-generating source (e.g., the control module 4, the power module 5, or the mobile device) adjacent thereto. The heat sink 71 transfers the absorbed heat to the air flowing through the surface thereof to heat the air, and the heated air is discharged under the pushing of the heat dissipation fan 72, thereby taking away the heat and achieving the heat dissipation purpose.

In some embodiments, the heat dissipating mechanism 7 may be equipped with a temperature sensor capable of monitoring the temperature of the heat sink 71 or critical heat generating components. When the temperature exceeds a certain threshold, the rotating speed of the cooling fan 72 is regulated by the control circuit, the rotating speed of the fan is increased to accelerate the air flow speed, the cooling effect is enhanced, the cooling efficiency is ensured to meet the cooling requirement, and when the temperature is reduced to a safe range, the rotating speed of the cooling fan 72 is properly reduced, so that the purposes of saving energy and reducing noise are achieved.

The application realizes the following beneficial effects by arranging the heat dissipation mechanism 7 of the mechanism:

firstly, through actively cooling the mobile equipment, the performance stability of the photographic expansion device of the mobile equipment is ensured.

Secondly, the temperature of the control module 4 and the power supply module 5 is effectively reduced, and overheat caused by heat accumulation generated by long-time operation is prevented. For example, when the mobile device photographs for a long time, a large amount of heat is generated from components such as a processor and a battery, and the heat dissipation mechanism 7 can maintain the temperature of the components within a safe working range, so that problems such as performance degradation, dead halt, automatic shutdown and the like caused by overheating are avoided.

With continued reference to fig. 4, in some embodiments, the heat dissipation mechanism 7 according to the present utility model further includes:

the heat dissipation fins 73 are disposed in the through groove 710 at intervals, and the heat dissipation fins 73 are located between the air outlet end of the heat dissipation fan 72 and the air outlet 1035.

In this embodiment, the heat dissipation fins 73 are disposed at intervals in the through grooves 710, so that when the air flow generated by the heat dissipation fan 72 flows through the heat dissipation fins 73, the air can fully contact with the surfaces of the plurality of heat dissipation fins 73, thereby expanding the heat exchange area and enabling more heat to be transferred from the heat dissipation seat 71 to the air flow. Because the rate of heat exchange is proportional to the contact area, a larger contact area means that more heat can be transferred out in the same time, thereby improving the heat dissipation capacity of the entire heat dissipation mechanism 7. The heat dissipation fins 73 are good mediums of heat conduction, and they can rapidly conduct the heat absorbed by the heat dissipation base 71 to the surface thereof. The heat radiation fins 73 are provided between the air outlet end of the heat radiation fan 72 and the air outlet 1035, and the hot air blown out from the heat radiation fan 72 can be further processed. When passing through the heat dissipation fins 73, the heat of the hot air is partially transferred to the fins, so that the temperature of the air finally discharged out of the air outlet 1035 is relatively reduced, and the heat dissipation effect is further optimized.

Referring to fig. 3, in some embodiments, the heat dissipation mechanism 7 according to the present utility model further includes a semiconductor heat conducting fin 74 disposed on a side of the heat dissipation base 71 facing the first surface 101 and corresponding to the heat dissipation fin 73;

Illustratively, the semiconductor heat-conducting strip 74 may conduct a directional transfer of heat via a die effect or a peltier effect, which will not be described in detail herein.

By arranging the semiconductor heat conducting fin 74, the expansion device can quickly and actively transfer the heat on the mobile equipment close to the first surface 101 to the heat radiating seat 71, so that the heat radiating mechanism 7 can be quickly cooled, and the heat radiating efficiency is greatly improved.
