[0040] In the prior art battery, heat is generally dissipated by setting a fan, but the air flow channel is not set reasonably and the heat dissipation efficiency is low.

[0041] The following is a preferred embodiment of a heat dissipation charger provided by the present invention that can solve the above technical problems.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The preferred embodiment of the utility model provides a heat dissipation charger, which includes a shell 11 and a PCB module 12. The shell 11 is a cube, and the shell 11 includes a first end plate 111, a second end plate 115, two side plates 112 and two panels 113. The first end plate 111 and the second end plate 115 are arranged in a transverse direction and parallel to each other. An air flow inlet 1111 is provided on the first end plate 111, and a fan 114 is provided at the air flow inlet 1111 for conveying air flow from the outside of the air flow inlet 1111 to the inside of the air flow inlet 1111. The second end plate 115 is provided with a power port for inputting AC power and an output port for outputting current. The two side panels 112 are arranged longitudinally and parallel to each other. The two side panels 112 are provided with an air duct 1121, an air inlet 1122 and an air outlet 1123. The air duct 1121 is located inside the side panel 112. The air inlet 1122 is located on the inner side of the end of the side panel 112 away from the air inlet 1111. The air outlet 1123 is located on the outer side of the end of the side panel 112 close to the air inlet 1111. The air inlet 1122 and the air outlet 1123 are both connected to the air duct 1121. The two air inlets 1122 and the air inlet 1111 are both connected to the inner cavity of the shell 11. The two panels 113 are arranged vertically and parallel to each other.

[0043] Please refer to Figure 2 and Figure 6 The PCB module 12 is arranged in the shell 11, and the PCB module 12 includes a plurality of heating plates 121. The plurality of heating plates 121 are divided into two groups and arranged on both longitudinal sides of the PCB module 12. Each group includes a plurality of heating plates 121. The plurality of heating plates 121 in each group are arranged horizontally and connected in parallel with the inner side surface of the side panel 112.

[0044] The heat dissipation charger of the utility model has two groups of heating sheets 121 that transfer heat to the two side plates 112 respectively. Under the action of the fan 114, the air at normal temperature enters the inner cavity of the shell 11 from the air inlet 1111 of the first end plate 111 and flows toward the second end plate 115. The airflow can take away the heat in the inner cavity of the shell 11 during the flow. After the airflow reaches the second end plate 115, it is divided into two branches. The two airflows enter the two air ducts 1121 through the two air inlets 1122 respectively, and are discharged from the corresponding air outlets 1123 respectively. The airflow can take away the heat of the two side plates 112 during the flow. The heat dissipation charger of the utility model can not only discharge the heat in the inner cavity of the shell 11, but also absorb the heat of the heating sheets 121 through the side plates 112, and by setting the air duct 1121 in the side plates 112, the heat of the side plates 112 can be effectively discharged, thereby improving the performance.

[0045] Please refer to Figure 2The heat dissipation charger also includes two heat conductive pads 13, which are respectively clamped between the two groups of heating sheets 121 and the two side panels 112. The multiple heating sheets 121 are arranged at intervals and of different sizes, and the heat they emit is different. The heat conductive pads 13 can quickly and evenly transfer the heat to the side panels 112, so that the heat distribution of the side panels 112 is uniform, so that the airflow can take away the heat when flowing everywhere in the air duct 1121, thereby improving the heat dissipation effect.

[0046] Please continue to refer to Figure 2 The heating sheet 121, the thermal pad 13 and the side plate 112 are welded by ultrasonic welding, so that the three are more closely attached to each other, which is beneficial to the heat transfer.

[0047] The thermal pad 13 is a thermally conductive silicone pad, and the thermal pad 13 with this structure absorbs heat faster.

[0048] Please refer to Figure 3 , Figure 4 and Figure 5 A plurality of partitions 1124 are arranged in the air duct 1121, and the plurality of partitions 1124 are evenly arranged vertically and parallel to each other. The plurality of partitions 1124 divide the air duct 1121 into a plurality of sub-air ducts 1125, and each sub-air duct 1125 extends horizontally. The air inlet 1122 is connected to one end of each of the plurality of sub-air ducts 1125, and the air outlet 1123 is connected to the other end of each of the plurality of sub-air ducts 1125. With the above structure, the air flow can flow into each sub-air duct 1125 evenly, thereby taking away the heat from all parts of the side plate 112.

[0049] Please refer to Figure 5 The air outlet 1123 is strip-shaped and extends vertically. The air outlet 1123 is arranged in a plurality of lateral directions. The air outlet 1123 is strip-shaped and has a small size, which can prevent large particles of debris from entering the housing 11 through the air outlet 1123. The air outlet 1123 is arranged in a plurality of lateral directions, which can discharge heat in a timely manner.

[0050] The side plate 112 is made of aluminum alloy, which allows the side plate 112 to quickly absorb heat and transfer it to all parts thereof.

[0051] The partition 1124 is made of aluminum alloy, which can transfer heat to the partition 1124 and evenly transfer heat to the outer wall of the side plate 112 to fully utilize the airflow and effectively take away the heat.

[0052] Please refer to Figure 2 The PCB module 12 also includes a PCB board 122, and a heat conductive material is coated on the PCB board 122. With the above structure, the heat generated by each component of the PCB module 12 can be evenly transferred to each part of the PCB board 122, and the airflow in the inner cavity of the housing 11 can be fully utilized to effectively take away the heat.

[0053] Please refer to Figure 2 The number of heating fins 121 in one group is greater than that in another group, and the airflow inlet 1111 is close to the group with more heating fins 121. With the above structure, the airflow in the group with more heating fins 121 can be larger, which is conducive to taking away the heat there.

[0054] The working principle of the heat dissipation charger of the preferred embodiment of the utility model:

[0055] The two groups of heating sheets 121 transfer heat to the two thermal pads 13 respectively. The two thermal pads 13 quickly absorb heat and evenly distribute it, and then transfer the heat to the two side panels 112. Under the action of the fan 114, the air at room temperature enters the inner cavity of the shell 11 from the air inlet 1111 of the first end plate 111, and flows toward the second end plate 115. The airflow can take away the heat in the inner cavity of the shell 11 during the flow process. After the airflow reaches the second end plate 115, it is divided into two branches. The two airflows enter the two air ducts 1121 through the two air inlets 1122, and enter each sub-air duct 1125, and are finally discharged from the corresponding air outlets 1123. The airflow can take away the heat of the two side panels 112 during the flow process.

[0056] This completes the working principle of the heat dissipation charger of this preferred embodiment.

[0057] The heat dissipation charger of the utility model has two groups of heating plates that transfer heat to the two side plates respectively. Air at room temperature enters the inner cavity of the shell from the air flow inlet of the first end plate under the action of the fan, and flows to the second end plate. The airflow can take away the heat in the inner cavity of the shell during the flow. After the airflow reaches the second end plate, it is divided into two branches. The two airflows enter the two air ducts through the two air inlets respectively, and are discharged from the corresponding air outlets respectively. The airflow can take away the heat of the two side plates during the flow. The heat dissipation charger of the utility model can not only discharge the heat in the inner cavity of the shell, but also absorb the heat of the heating plates through the side plates, and by setting air ducts in the side plates, the heat of the side plates can be effectively discharged, thereby improving performance.

[0058] To sum up, although the present invention has been disclosed as above in the form of preferred embodiments, the protection scope of the present invention is not limited thereto, and any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the concept of the technical solution of the present invention, which should be covered by the protection scope of the present invention.
