By controlling the current, the thermoelectric first end 711 can be made to be a heating end and the thermoelectric second end 712 can be made to be a cooling end, or the thermoelectric first end 711 can be made to be a cooling end and the thermoelectric second end 712 can be made to be a heating end, so as to achieve the effect of heating or cooling the mobile phone 200, and to make the temperature of the battery of the mobile phone 200 be at the optimal operating temperature.

When the thermoelectric first end 711 is a heating end and the thermoelectric second end 712 is a cooling end, the thermoelectric first end 711 transfers the generated heating effect upwards to the first heat conducting member 11, so as to heat the mobile phone 200, and simultaneously, the cooling effect generated by the thermoelectric second end 712 is transferred downwards to the third heat conducting member 72. This situation can be used in a low temperature environment to preheat the battery of the mobile phone 200, so that the battery of the mobile phone 200 is at a better operating temperature, thereby improving the charging efficiency, reducing the performance loss of the battery, and prolonging the service life of the battery.

When the thermoelectric first end 711 is a cooling end and the thermoelectric second end 712 is a heating end, the thermoelectric first end 711 transfers the generated cooling effect upwards to the first heat conducting member 11, so as to cool the mobile phone 200, and simultaneously, the heating effect generated by the thermoelectric second end 712 is transferred downwards to the third heat conducting member 72. This situation can be used to cool the battery of the mobile phone 200 when the temperature of the battery of the mobile phone 200 is high, so that the battery of the mobile phone 200 is at the optimum operating temperature, thereby improving the charging efficiency, reducing the performance loss of the battery, and prolonging the service life of the battery.

In order to transfer the heat generated by the thermoelectric first end 711 upwards and the heat generated by the thermoelectric second end 712 downwards as much as possible, and reduce the influence of the upward transfer of the energy generated by the thermoelectric second end 712 on the heating or cooling effect of the thermoelectric first end 711, the charging temperature control device 100 further includes a heat insulator 73.

The size of the through-hole 731 is adapted to the thermoelectric material layer 71 such that the thermoelectric material layer 71 can be placed in the through-hole 731, and then the thermal insulation member 73 can reduce the heat exchange between the thermoelectric first end 711 and the thermoelectric second end 712, reduce the downward transfer amount of energy generated by the thermoelectric first end 711, and reduce the upward transfer amount of energy generated by the thermoelectric second end 712, i.e., reduce the influence of the thermoelectric second end 712 on the thermoelectric first end 711.

As shown in fig. 9, three through holes 731 may be formed in the heat insulator 73, and the three through holes 731 are arranged in parallel and at intervals along the second direction Y, and accordingly, the number of the thermoelectric material layers 71 is also three, and the three thermoelectric material layers 71 are respectively arranged in the three through holes 731.

The refrigerating device 8 is disposed in the heat dissipation space 13, and the upper and lower ends of the refrigerating device 8 along the first direction Z are respectively abutted to the first heat conducting member 11 and the heat conducting fins 2, that is, the first heat conducting member 11, the refrigerating device 8, the heat conducting fins 2 and the second heat conducting member 12 are sequentially arranged along the first direction Z.

The refrigerating apparatus 8 includes a liquid-cooled power pump 81 and a liquid-cooled pipe 82. The liquid cooling power pump 81 is arranged on the substrate 1, and two ends of the liquid cooling pipe 82 are respectively connected with the liquid cooling power pump 81 and form a loop with the liquid cooling power pump 81, so that cooling liquid in the liquid cooling pipe 82 can circulate between the liquid cooling power pump 81 and the liquid cooling pipe 82.

In the circulation process of the cooling liquid, the heat emitted by the first heat conducting member 11 can be absorbed, and the temperature of the first heat conducting member 11 is reduced by the refrigerating effect of the liquid cooling power pump 81, so that the mobile phone 200 can uniformly dissipate the heat. Meanwhile, the heat dissipated by the cooling liquid can be transferred to the heat conducting fins 2, so that a quick heat exchange effect is achieved.

The cooling device 8 further includes an exhaust plenum 83, a first liquid cooling fin 84, a second liquid cooling fin 85, a first exhaust port 86, and a second exhaust port 87.

The first liquid cooling fins 84 and the second liquid cooling fins 85 are staggered to form a serpentine airflow path in the exhaust plenum 83. When gas circulates in the serpentine airflow channel, the gas can fully contact the first liquid cooling fins 84 and the second liquid cooling fins 85, and a good heat exchange effect is achieved.

The liquid cooling pipe 82 comprises two parts, one part is in contact with the heat conduction fins 2 and the first heat conduction piece 11 in the heat dissipation space 13, the other part is in contact with the first liquid cooling fins 84 and the second liquid cooling fins 85 in the exhaust containing cavity 83, so that the cooling liquid can act on the first heat conduction piece 11 with a refrigeration effect in a circulation process, heat can be transferred to the first liquid cooling fins 84 and the second liquid cooling fins 85, and then the heat on the first liquid cooling fins 84 and the second liquid cooling fins 85 is dissipated through the flowing of gas in the serpentine airflow channel.

The cooling device 8 further includes a cooling fan 88, and the cooling fan 88 is provided at any one of the first exhaust hole 86 and the second exhaust hole 87. The cooling fan 88 can increase the flow velocity of the air in the exhaust plenum 83, thereby further increasing the heat dissipation effect.

Specifically, the number of the cooling fans 88 may be one or two. When the number of the cooling fans 88 is one, the cooling fans 88 may be disposed at the first exhaust holes 86 or the second exhaust holes 87 to accelerate the flow rate of the gas by blowing the external gas into the exhaust cavity 83, thereby improving the heat exchange effect. When the number of the cooling fans 88 is two, the two cooling fans 88 are respectively disposed at the first exhaust hole 86 and the second exhaust hole 87, so that the blowing directions of the two cooling fans 88 are the same, the flow velocity of the gas in the exhaust cavity 83 is accelerated, and the heat exchange effect is improved.

Further, the liquid cooling tube 82 of the heat dissipation space 13 is serpentine, so that the heat exchange effect with the first heat conduction member 11 and the heat conduction fins 2 can be improved.

Further, the refrigeration device 8 further includes a phase change filler 3, and the phase change filler 3 is filled inside the liquid cooling pipe 82 in the heat dissipation space 13. The phase change filler 3 can further enhance the heat exchange effect of the liquid cooling tube 82.
