The blowing device 20 is arranged outside the shell 11. And the blowing device 20 is communicated with the air inlet 14.

The shell 11 can be used for sound insulation, and the shell 11 can also protect the heat generating device 30 from dust and other impurities, and the shell 11 can also reduce the problem of accidental touching of the heat generating device 30. In this embodiment, the shell 11 is approximately a rectangular body, and in other embodiments, the shell 11 can also be a cylindrical body, a polygonal body, etc. In this embodiment, the shell 11 is a plastic heat dissipation structure 10, and in other embodiments, the shell 11 can also be a metal shell 11, a composite material shell 11, etc. The air inlet 14 can be used for the air blowing device 20 to blow air into the containing space, and in some embodiments, the shell 11 is provided with a connecting structure at the air inlet 14.

In addition, the shape of the air inlet 14 and the air outlet 15 can be triangular, circular, square or irregular polygon, etc. The air guide structure is used to guide the air to blow to the heat generating device 30 in the containing space, so that more air flows through the heat generating device 30, and the heat dissipation effect is improved. The air guide structure can include a plurality of air guide surfaces, and the plurality of air guide surfaces can be arranged at intervals inside the containing space.

[0042] The above heat dissipation structure 10 can play the role of sound insulation and protection of the heat generating device 30. The air can be blown into the shell 11 through the air inlet 14 on the shell 11 to accelerate the air flow, and the heat generated by the heat generating device 30 can be taken away and blown out from the air outlet 15, so as to reduce the heat accumulation and reduce the aging and wear of the heat generating device 30.

[0043] In some embodiments, the air inlet 14 and the air outlet 15 are respectively arranged on the shell walls of the opposite sides of the shell 11, which facilitates the air flow in the accommodating space. In some embodiments, the air inlet 14 is arranged on the shell wall of the top of the shell 11, and the air outlet 15 is arranged on the shell wall of the bottom of the shell 11.

In some other embodiments, the air inlet 14 and the air outlet 15 can also be arranged on the same shell wall of one side of the shell 11. The arrangement of the air inlet 14 and the air outlet 15 on the shell walls of the opposite sides of the shell 11 makes the air entering the accommodating space from one side flow out from the opposite side, which can accelerate the air flow in the accommodating space and improve the heat dissipation effect.

[0044] In some embodiments, the shell 11 comprises a mounting bottom plate 113, a soundproof cover 112 and a cover plate 111. The mounting bottom plate 113 and the cover plate 111 are respectively connected to the opposite ends of the soundproof cover 112, and the mounting bottom plate 113, the soundproof cover 112 and the cover plate 111 jointly define an accommodating cavity (not shown) in which the accommodating space is arranged.

In some preferred embodiments, the inner wall of the soundproof cover 112 is further provided with soundproof folds, which can improve the soundproof effect of the soundproof cover 112. In some other embodiments, the soundproof cover 112 has a double-layer hollow structure, which can improve the soundproof effect of the soundproof cover 112 through the cavity. The cover plate 111 is arranged on the upper portion of the soundproof cover 112 and jointly defines the accommodating space with the soundproof cover 112 and the mounting bottom plate 113.

The air inlet 14 and the air outlet 15 are arranged on the opposite sides of the accommodating space in a second direction. The first direction is perpendicular to the second direction. The arrangement of the air inlet 14 and the air outlet 15 in the above manner makes the projection of the air inlet 14 on the mounting plate not on the same side as the air outlet 15, so that the air blowing from the air inlet 14 will not directly blow out from the air outlet 15 from top to bottom, which facilitates the air blowing from the air inlet 14 to flow towards the heat generating device 30 in the accommodating space, accelerates the air flow around the heat generating device 30 in the accommodating space, and accelerates the heat dissipation.

[0048] In some embodiments, the air guiding structure is provided with an air guiding surface 160 extending from the air inlet 14 to the accommodating space. The air guiding surface 160 faces the heat generating device 30 in the accommodating space and the air inlet 14, so as to guide the air blown into the air inlet 14 to the heat generating device 30, thereby improving the heat dissipation effect. The number of the air guiding surface 160 is one or more.

[0049] In some embodiments, the air guiding structure is provided with a wind blocking surface 120 extending from the air inlet 14 to the accommodating space. The wind blocking surface 120 is arranged in a spaced manner with the air guiding surface 160, and the air guiding surface 160 and the wind blocking surface 120 form an air guiding channel 17. The end of the wind blocking surface 120 away from the air inlet 14 extends to the top end of the accommodating space, and the wind blocking surface 120 faces the air guiding surface 160, so that the air entering the air inlet 14 can be guided to the heat generating device 30, thereby avoiding the air entering the air inlet 14 from passing through the top of the heat generating device 30 and affecting the heat dissipation efficiency. The wind blocking surface 120 and the air guiding surface play a converging role on the wind, so that the air can be blown along the air guiding channel 17 to the heat generating device 30, and more air can pass through the heat generating device 30, thereby improving the heat dissipation effect. The top end of the accommodating space is the end of the accommodating space away from the air outlet 15.

[0053] In some embodiments, the air guiding member 16 and the wind blocking member 12 are arranged in a spaced manner, and an air guiding channel 17 is arranged between the air guiding member 16 and the wind blocking member 12. The air guiding member 16 and the wind blocking member 12 are arranged on opposite sides of the air inlet 14, so that the air at the air inlet 14 can enter the air guiding channel 17. The air guiding surface 160 is arranged on the side of the air guiding member 16 facing the wind blocking member 12, and the wind blocking surface 120 is arranged on the side of the wind blocking member 12 facing the air guiding member 16.

[0054] In some embodiments, the air guiding member 16 and the wind blocking member 12 are integrally formed with the shell 11. That is, the air guiding surface 160 and the wind blocking surface 120 are formed by the shell wall of the shell 11, which simplifies the structure of the heat dissipation structure 10. It can be understood that, in some embodiments, the air guiding member 16 and the wind blocking member 12 can be separately arranged, which is not limited herein.

[0055] In addition, in some embodiments, the number of air inlets 14 on the shell 11 is multiple, and the number of air outlets 15 is multiple. Specifically, in the present embodiment, the number of air inlets 14 and the number of air outlets 15 on the shell 11 are both two, and the two air inlets 14 can be used to supply air to the accommodating space by two air blowing devices 20 at the same time, which can improve the heat dissipation effect. In some other embodiments, the number of air inlets 14 and the number of air outlets 15 can also be one, three, etc.

[0056] Further, in the present embodiment, the two air inlets 14 are located on the cover plate 111 of the shell 11, that is, the two air inlets 14 are located on the same side of the shell 11. In some other embodiments, the two air inlets 14 can also be located on different sides of the shell 11, for example, one air inlet 14 is located on the cover plate 111 and the other air inlet 14 is located on the mounting bottom plate 113, so as to blow air to the accommodating space from multiple angles and improve the heat dissipation effect. Similarly, in the present embodiment, the two air outlets 15 are located on the same side of the shell 11, and in some other embodiments, the two air outlets 15 can also be located on different sides of the heat dissipation structure 10, for example, one air outlet 15 is located on the cover plate 111 and the other air outlet 15 is located on the mounting bottom plate 113.

[0057] In some embodiments, the air inlets 14 and the air outlets 15 can also have a hollow structure. The hollow structure design can make the air inlets 14 and the air outlets 15 not affect the structural strength of the shell 11.
