DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] Hereinafter, the terms "including", "having" and their cognates used in various embodiments of the present invention are intended only to indicate specific features, numbers, steps, operations, elements, components or combinations of the foregoing items, and should not be understood as first excluding the existence of one or more other features, numbers, steps, operations, elements, components or combinations of the foregoing items or adding the possibility of one or more features, numbers, steps, operations, elements, components or combinations of the foregoing items.

[0033] In addition, if the present invention involves the terms "first", "second", "third", etc., they are only used to distinguish and describe, and cannot be understood as indicating or implying relative importance.

[0034] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meanings as those generally understood by ordinary technicians in the field to which the various embodiments of the present invention belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in various embodiments of the present invention.

[0035] refer to Figure 1 In order to more conveniently explain the present invention, an X, Y, and Z reference coordinate system is established to assist in explaining the relationship between the layout directions of the components. Figure 1 For example, the X direction is the width direction of the shell, the Y direction is the length direction of the shell, the Z direction is the thickness direction or the vertical direction of the shell, and the X, Y, and Z directions each have two opposite sides. This coordinate system only serves as an auxiliary explanation and should not be regarded as limiting the actual layout position of the components of the utility model.

[0036] See also Figure 1 , 2 , 3, 4, the refrigeration mobile charging power supply 100 provided in the embodiment of the utility model comprises:

[0037] The housing 1 has a receiving chamber 11 formed therein, and the receiving chamber 11 is divided into at least a first area 112 and a second area 113 (see Figure 2 , 4 As shown in the figure, an air inlet area 12 and an air outlet area 13 are formed through one or more sides of the housing 1, and external air (or room temperature air) enters the accommodating cavity 11 from the air inlet area 12 and is discharged from the air outlet area 13;

[0038] Those skilled in the art will understand that the accommodating cavity 11 is used to accommodate rechargeable batteries and semiconductor cooling chips (the installation method and working characteristics of the semiconductor cooling chips will be described below). These two components will generate a lot of heat during operation. In order to avoid heat accumulation, the best way is to arrange them in partitions, so that the heat can be discharged from the outside of the accommodating cavity 11 more quickly, which can effectively improve the heat dissipation effect of the utility model.

[0039] When external air enters the accommodating cavity 11 from the air inlet area 12, it will exchange heat with components in the accommodating cavity 11, such as rechargeable batteries or semiconductor cooling plates, so that the temperature of the components in the accommodating cavity 11 will be reduced, and the temperature of the external air in the accommodating cavity 11 will rise to form hot air, and then be discharged from the air outlet area 13, thereby bringing the heat in the accommodating cavity 11 out of the accommodating cavity 11. In this way, a relatively low temperature can be maintained in the accommodating cavity 11, thereby ensuring the normal working performance of components such as rechargeable batteries and semiconductor cooling plates, improving user experience, and reducing the risk of spontaneous combustion.

[0040] It should be noted that in the embodiment of the utility model, the shell 1 can be divided into two parts, one part is the bottom shell 1a, and the other part is the upper cover 1b. The upper cover 1b can be separated from the bottom shell 1a in the Z direction, or the upper cover 1b can be covered on the bottom shell 1a.

[0041] In other embodiments, similarly, the housing 1 may be divided into two parts, and the two parts may be arranged to be separated in the X direction, or separated in the Y direction.

[0042] A rechargeable battery 2, the rechargeable battery 2 is accommodated in the first area 112;

[0043] In the embodiment of the present invention, the rechargeable battery 2 and the first region 112 are both made into a rectangular parallelepiped structure, and the rechargeable battery 2 and the first region 112 can be compactly matched together.

[0044] The heat dissipation bracket 3 is arranged in the second area 113, the air inlet area 12 and the air outlet area 13 are respectively connected to the second area 113, and the heat dissipation bracket 3 includes a heat absorption part 31 and a heat dissipation part 32;

[0045] Specific to Figure 4 In the illustrated embodiment, the portion where the upper side of the heat dissipation bracket 3 contacts the heating side of the semiconductor cooling plate substantially forms the heat absorption portion 31, and the rest of the heat dissipation bracket 3 except the heat absorption portion 31 can be regarded as the heat dissipation portion 32. In order to ensure a better heat dissipation effect, the heat dissipation bracket 3 is usually made of a metal material with good thermal conductivity, such as aluminum.

[0046] During the operation of the utility model, the heat dissipation bracket 3 is used to dissipate heat for the semiconductor cooling sheet 4. If the heat dissipation bracket 3 is not cooled in time, the heat dissipation bracket 3 will be in a relatively high temperature state and will not be able to dissipate heat for the semiconductor cooling sheet well, thereby affecting the cooling effect of the semiconductor cooling sheet, and the accommodating cavity 11 will also be in a high temperature state. The air inlet area 12 is connected to the space where the heat dissipation bracket 3 is located, so that the air at room temperature can more conveniently exchange heat with the heat dissipation bracket 3.

[0047] The semiconductor refrigeration sheet 4 is electrically connected to the rechargeable battery 2, the semiconductor refrigeration sheet 4 is powered by the rechargeable battery 2, the heat-generating side of the semiconductor refrigeration sheet 4 is connected to the heat-absorbing portion 31, and the cooling side of the semiconductor refrigeration sheet 4 is connected to the heat-absorbing portion 31 through the first heat-conducting layer (hereinafter referred to as Figure 5 The first heat-conducting layer is described) and is heat-conductingly connected to an inner wall of one side surface of the housing 1;

[0048] An adaption circuit is also required to be provided between the rechargeable battery 2 and the semiconductor refrigeration sheet 4 to adapt the voltage and current suitable for the semiconductor refrigeration sheet 4 to work properly. Since one surface of the semiconductor refrigeration sheet 4 is in a heating state and the other surface is in a cooling state during operation. The heating side of the semiconductor refrigeration sheet 4 needs to dissipate the heat conveniently to ensure the cooling effect of the semiconductor refrigeration sheet 4. Therefore, in order to facilitate heat dissipation, the heating side of the semiconductor refrigeration sheet 4 is thermally connected to the heat absorption part 31. In this embodiment, the heating side of the semiconductor refrigeration sheet 4 is directly attached to the heat absorption part 31. The heat absorption part 31 can be set to a flat structure to contact the heating side of the semiconductor refrigeration sheet 4 as much as possible, and in order to better perform heat exchange, a coating such as thermal conductive silicone grease can also be coated.

[0049] The cooling side of the semiconductor cooling sheet 4 is actually used to cool handheld electronic devices, such as tablets, mobile phones and other electronic products during operation. Handheld electronic devices will generate a lot of heat during long-term use. If they are not cooled in time, the operation smoothness of the handheld electronic devices will be greatly reduced, which will reduce the user experience.

[0050] It should be noted that the refrigeration mobile charging power supply 100 of the present invention is used in conjunction with a handheld electronic device. Since the present invention is equipped with a rechargeable battery 2, the refrigeration mobile charging power supply 100 of the present invention and the handheld electronic device can be conveniently carried during use without being restricted by a power cord.

[0051] In one embodiment, the inner wall of one side of the shell 1 is tightly connected to the cooling side of the semiconductor refrigeration plate 4, wherein this side of the shell 1 is a side in contact with the handheld electronic device. Therefore, the cooling side of the semiconductor refrigeration plate 4 can cool the handheld electronic product through this side of the shell 1.

[0052] Those skilled in the art will understand that the side of the housing 1 that contacts the handheld electronic device can be made of a material with good thermal conductivity, such as metal or silicone material with good thermal conductivity, such as aluminum. Even a hole can be made for the cooling side of the semiconductor cooling sheet 4 so that the cooling side of the semiconductor cooling sheet 4 is in direct contact with the handheld electronic device.

[0053] A first fan 5a, wherein the first fan 5a is used to dissipate heat from the heat dissipation portion 32;

[0054] The function of the first fan 5a is to accelerate the heat dissipation of the heat dissipation portion 32, for example, it can directly blow air to the heat dissipation portion 32 (that is, blow away the hot air in the heat dissipation channel 322), so as to Figure 3 and Figure 4 For example, one working mode of the first fan 5a is to blow air downward (toward the bottom of the accommodating cavity 11), and the hot air flows downward from the heat dissipation channel 322 through the vent 142; it can also blow air upward (that is, blow air away from the bottom of the accommodating cavity 11). At this time, due to the action of the first fan 5a, the air flow on the surface of the heat dissipation part 32 will be accelerated, and the heat exchange of the heat dissipation part 32 will be accelerated, ensuring that the heat dissipation part 32 is in a relatively low temperature state, thereby maintaining the heat dissipation effect of the heat dissipation bracket 3.

[0055] The second fan 5 b is used for exhausting air from the air outlet area 13 .

[0056] refer to Figure 2 ,3 In the embodiment shown in 4, in order to better exhaust air, the air outlet of the second fan 5b is opposite to the air outlet area 13. Preferably, the second fan 5b adopts a turbofan, and the turbofan is arranged close to the inner wall of one side of the accommodating chamber 11 and is located in the second area 113. The turbofan has a lateral air inlet 51 and a forward air outlet 52. Such an arrangement facilitates the hot air in the accommodating chamber 11 to be sucked into the turbofan from the air inlet 51 and sent out from the air outlet 52. Since the air outlet 52 is opposite to the air outlet area 13, the air is finally exhausted through the air outlet area 13.

[0057] refer to Figure 4 As shown, the heat absorption part 31 is a flat structure, the heat dissipation part 32 is provided with a plurality of heat dissipation fins 321, a heat dissipation channel 322 is formed between two adjacent heat dissipation fins 321, and the heat dissipation part 32 is also provided with a fan slot (not shown in the figure), and the first fan 5a is installed in the fan slot.

In this way, when the first fan 5a is installed in the fan slot, the first fan 5a can perform immersion cooling on the heat dissipation bracket 3, that is, it can form airflow in all the heat dissipation channels 322 to take away the heat of the heat dissipation part 32.

[0072] Specifically, the wireless charging coil 9 is adapted to the rechargeable battery 2 through the charge and discharge control circuit board 8. Since the function of the wireless charging coil 9 is to wirelessly charge the handheld electronic device, it must be arranged as close as possible to or even close to the inner wall of one side of the housing 1, and the outer wall of this side is the connection surface for connecting with the handheld electronic device to facilitate wireless charging.
