[0034] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] Example 1

[0036] refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a heat dissipation structure 100 , which includes a housing assembly 110 , a partition 120 , an inductor assembly 130 and a heat dissipation fan 140 .

[0037] Specifically, Figure 2 and Figure 3As shown, the housing assembly 110 defines a housing cavity 113; the partition 120 divides the housing cavity 113 into a first cavity 1131 and a second cavity 1132, and the partition 120 has a first opening 121; the inductor assembly 130 is disposed in the first cavity 1131; the cooling fan 140 is installed in the first opening 121, and the cooling fan 140 is disposed in the second cavity 1132. The housing cavity 113 of the housing assembly 110 is divided into the first cavity 1131 by the partition 120. and the second cavity 1132, the inductor component 130 and the cooling fan 140 are respectively installed in the first cavity 1131 and the second cavity 1132, so that the inductor component 130 and the cooling fan 140 are separated by the partition 120, and the two will not affect or hinder each other. The cooling fan 140 blows air toward the first cavity 1131 through the first opening 121 to dissipate heat and cool down the inductor component 130, reduce the wind turbulence of the cooling fan 140, reduce wind noise to improve user experience, and maintain the flow and smoothness of the blowing air duct.

[0038] It can be understood that the partition 120 is used to guide the airflow generated by the cooling fan 140 to flow in a specific direction, thereby avoiding reverse airflow convection causing wind chaos, reducing wind noise, and improving ventilation efficiency, maintaining the environmental stability of the position of the inductor component 130 in the accommodating cavity 113.

[0039] It should be noted that the reference Figures 1 to 3 As shown, the first direction X is taken as the width direction of the heat dissipation structure 100, the second direction Y is taken as the length direction of the heat dissipation structure 100, and the third direction Z is taken as the height direction of the heat dissipation structure 100, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicularly to each other. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of the heat dissipation structure 100, and should not be understood as a limitation to the present application.

[0040] In one embodiment, optionally, reference Figure 2 As shown, the number of the cooling fans 140 is two, the number of the first openings 121 is two, one cooling fan 140 corresponds to one first opening 121, and the two cooling fans 140 are arranged side by side along the first direction X. The two cooling fans 140 arranged side by side further improve the heat dissipation and cooling efficiency.

[0041] Optionally, combined Figure 2 and Figure 3As shown, the heat dissipation structure 100 also includes a plurality of groups of heat dissipation fins 150, any of the heat dissipation fins 150 are arranged in the first cavity 1131, and the plurality of groups of heat dissipation fins 150 and the inductor component 130 are staggered. In other words, the plurality of groups of heat dissipation fins 150 are all located in the first cavity 1131. The staggered arrangement of the heat dissipation fins 150 and the inductor component 130 makes the structures of the two more compact, with high space utilization, and reduces thermal interference between each other, so as to cool and dissipate the inductor component 130 in the first cavity 1131. Exemplarily, the heat dissipation fins 150 are arranged around the inductor component 130 to enhance the heat dissipation and cooling effect on the inductor component 130.

[0042] In this embodiment, the heat sink 150 is classified as a "passive heat sink element" in the field of electronic engineering design. It is attached to the heat-generating surface with a metal that has good thermal conductivity, is light in weight, and is easy to process (mostly aluminum or copper; silver is too expensive and is generally not used). The heat is dissipated in a composite heat exchange mode. After the heat sink 150 absorbs the heat, it dissipates the heat in the form of convection. In the process of convection heat dissipation, the heat dissipation area is mainly determined by the size of the surface area of ​​the heat sink 150. The larger the surface area, the better the heat dissipation effect.

[0043] In one embodiment, optionally, reference Figure 1 and Figure 2 As shown, the housing assembly 110 includes a housing 111 and a cover 112. The housing 111 is provided with a second opening 1111; the cover 112 covers the second opening 1111, and the cover 112 is connected to the housing 111 and defines the accommodating cavity 113, so that the inductor assembly 130 in the housing 111 can be installed and maintained by opening the cover 112, which has a better technical effect.

[0044] Alternatively, if Figure 1 As shown, a plurality of exhaust ports 1112 are provided at opposite ends of the shell 111 along the second direction Y. The second direction Y is perpendicular to the first direction X. The exhaust ports 1112 can form an air flow channel with the heat dissipation fan 140 to facilitate the dissipation of heat generated by the inductor component 130 in the accommodating cavity 113, thereby improving the overall heat dissipation and cooling effect of the heat dissipation structure 100. Demonstratively, the exhaust ports 1112 are arranged relative to the heat dissipation fan 140 along the second direction Y.

[0045] In summary, the accommodating cavity 113 of the shell component 110 in the heat dissipation structure 100 is divided into a first cavity 1131 and a second cavity 1132 by a partition 120, and the inductor component 130 and the heat dissipation fan 140 are respectively installed in the first cavity 1131 and the second cavity 1132, so that the inductor component 130 and the heat dissipation fan 140 are separated by the partition 120, and the two will not affect or hinder each other. The heat dissipation fan 140 blows air toward the first cavity 1131 through the first opening 121 to dissipate heat and cool down the inductor component 130, reduce the turbulence of the heat dissipation fan 140, reduce wind noise to improve user experience, maintain the flow and smoothness of the blowing air duct, and improve the overall heat dissipation and cooling effect of the heat dissipation structure 100.

The housing cavity 113 of the housing assembly 110 is divided into the first cavity 1131 by the partition 120. and the second cavity 1132, the inductor component 130 and the cooling fan 140 are respectively installed in the first cavity 1131 and the second cavity 1132, so that the inductor component 130 and the cooling fan 140 are separated by the partition 120, and the two will not affect or hinder each other. The cooling fan 140 blows air toward the first cavity 1131 through the first opening 121 to dissipate heat and cool down the inductor component 130, reduce the wind turbulence of the cooling fan 140, reduce wind noise to improve user experience, and maintain the flow and smoothness of the blowing air duct.

[0049] It should be noted that the reference Figures 1 to 3 As shown, the first direction X is taken as the width direction of the heat dissipation structure 100, the second direction Y is taken as the length direction of the heat dissipation structure 100, and the third direction Z is taken as the height direction of the heat dissipation structure 100, wherein the first direction X, the second direction Y and the third direction Z are arranged perpendicularly to each other. It can be understood that the above definition is only for the convenience of understanding the relative position relationship of the heat dissipation structure 100, and should not be understood as a limitation to the present application.

The two cooling fans 140 arranged side by side further improve the heat dissipation and cooling efficiency.

[0051] Alternatively, if Figure 3 As shown, the heat dissipation structure 100 also includes a shock absorber 141. The heat dissipation fan 140 is installed at the bottom of the accommodating cavity 113. The shock absorber 141 is arranged between the heat dissipation fan 140 and the bottom of the accommodating cavity 113. The shock absorber 141 can balance the load and optimize the shock absorption effect. The shock absorber 141 can increase the static stress of the heat dissipation fan 140 and reduce the noise generated during the operation of the heat dissipation fan 140. Exemplarily, the shock absorber 141 can be one of a rubber pad, a spring shock absorber or an elastic frame.

[0052] Optionally, combined Figure 2 and Figure 3 As shown, the heat dissipation structure 100 also includes a plurality of groups of heat dissipation fins 150, any of the heat dissipation fins 150 are arranged in the first cavity 1131, and the plurality of groups of heat dissipation fins 150 and the inductor component 130 are staggered. In other words, the plurality of groups of heat dissipation fins 150 are all located in the first cavity 1131. The staggered arrangement of the heat dissipation fins 150 and the inductor component 130 makes the structures of the two more compact, with high space utilization, and reduces thermal interference between each other, so as to cool and dissipate the inductor component 130 in the first cavity 1131. Exemplarily, the heat dissipation fins 150 are arranged around the inductor component 130 to enhance the heat dissipation and cooling effect on the inductor component 130.

The housing 111 is provided with a second opening 1111; the cover 112 covers the second opening 1111, and the cover 112 is connected to the housing 111 and defines the accommodating cavity 113, so that the inductor assembly 130 in the housing 111 can be installed and maintained by opening the cover 112, which has a better technical effect.

[0054] Alternatively, if Figure 1As shown, a plurality of exhaust ports 1112 are provided at opposite ends of the shell 111 along the second direction Y. The second direction Y is perpendicular to the first direction X. The exhaust ports 1112 can form an air flow channel with the heat dissipation fan 140 to facilitate the dissipation of heat generated by the inductor component 130 in the accommodating cavity 113, thereby improving the overall heat dissipation and cooling effect of the heat dissipation structure 100. Demonstratively, the exhaust ports 1112 are arranged relative to the heat dissipation fan 140 along the second direction Y.

[0055] In this embodiment, two opposite ends of the housing 111 along the second direction Y extend to form gripping portions, so that the housing 111 can be moved and carried by the gripping portions of the housing 111 .
