The implementation details of the high-efficiency heat dissipation communication transmission device of the present embodiment are specifically described below, and the following description is provided only for convenience of understanding, and is not necessary to implement the present embodiment.

The housing case 10 is used for housing the exhaust fan 20, the heating module 30 and the battery module 40, thereby supporting and protecting the exhaust fan 20, the heating module 30 and the battery module 40. In an alternative, the housing 10 may be made by injection molding, and the material of the housing 10 may be a hard material, and the housing 10 made of the hard material has the characteristics of hard texture, difficult deformation and high strength. In addition, the housing case 10 may be formed by splicing a plurality of separately manufactured components, which is more conducive to manufacturing a case having a special shape, so that the complex case shape is easier to manufacture. In one embodiment, the housing 10 includes a rear housing 13, a front housing 14, and a trim 15. The rear case 13 has a plate-like body 130, and the front case 14 is supported by the plate-like body 130 at its edge position, with the garnish 15 being located above the front case 14. Specifically, the front shell 14 includes a side wall 140 perpendicular to the main body 130, the side wall 140 is disposed at an edge of the main body 130, and encloses the accommodating cavity 100 with the main body 130, the rear shell 13 is located at a bottom of the accommodating cavity 100, and the decoration 15 covers a top of the front shell 14.

The air inlet 11 and the air outlet 12 are openings formed on the front shell 14, and are respectively communicated with the accommodating cavity 100 to allow the air outside the accommodating shell 10 to flow into and out of the accommodating cavity 100, and it is understood that the air inlet 11 and the air outlet 12 may be directly formed on the front shell 14 by integral injection molding. In addition, for convenience in air flow smoothness, the air inlet 11 and the air outlet 12 can be opposite to each other, so that the air flow can flow quickly, and higher heat dissipation efficiency can be achieved. However, in a special application environment, such as a cold region, the heat dissipation efficiency does not need to be very high, and the air inlet 11 and the air outlet 12 may be arranged in a position according to other design considerations without being arranged relatively.

In fig. 2 of the example of the present utility model, as an alternative embodiment, the air inlet 11 and the air outlet 12 are disposed at left and right sides of the front case 14 opposite to each other. Specifically, the air inlet 11 is disposed on the side wall 140, and the opening direction of the air inlet 11 (i.e. the left-right direction of the drawing in fig. 2) is parallel to the main body 130; the air outlet 12 is disposed on the other side wall 140 opposite to the side wall 140 where the air inlet 11 is disposed, and the opening direction of the air outlet 12 is parallel to the main body 130. The opening direction of the air inlet 11 is parallel to the main body 130, so that turbulence caused by the fact that air entering the accommodating shell 10 is directly blown onto the rear shell 13 positioned at the bottom of the accommodating cavity 100 can be avoided, and further the flowing efficiency of heat dissipation air flow is prevented from being influenced; the opening direction of the air outlet 12 is also parallel to the main body 130, so that the air flow discharging direction is consistent with the air inlet direction, and the air flow circulation efficiency is further ensured. Of course, in a modified embodiment, the air outlet 12 may be provided on the decoration 15 such that the opening direction of the air outlet 12 is perpendicular to the main body 130.

The exhaust fan 20 is disposed in the housing 10 and adjacent to the air outlet 12, so as to exhaust the air entering the housing 10 from the air inlet 11 and absorbing heat to the outside of the housing 10 through the air outlet 12. In addition, the air flow is more rapid under the pushing of the exhaust fan 20, so that the air flow is further increased, and the heat dissipation efficiency is improved.

The heating module 30 is disposed in the housing 10, is spaced from the top wall of the housing 10, and forms a first air duct 101 communicating the air inlet 11 and the air outlet 20. Specifically, in an alternative embodiment, the heat generating module 30 includes a circuit board 31, and a heat generating module 32 and a shielding case 33 disposed on the circuit board 31. In order to facilitate the heat of the heat generating module 32 to be dissipated to the surrounding air as soon as possible, the heat generating module 30 may further include a heat sink 34 disposed on the heat generating module 32, so that the heat sink 34 and the top wall of the housing case 10 are spaced from each other to form the first air channel 101. By means of the arrangement, the radiator 34 is utilized to absorb and disperse heat from the heating module 32 in advance, and then the heat dissipation area of the radiator 34 is larger than that of the heating module 32, so that higher heat transfer/dissipation efficiency is achieved, and then heat is transferred into the air flow in the first air duct 101 through heat exchange between the radiator 34 and the air flow in the first air duct 101.

The battery module 40 is disposed in the housing 10 and provides electric energy for the heating module 30, and the battery module 40 is disposed below the heating module 30 and is spaced apart from the heating module 30 to form a second air duct 102 communicating the air inlet 11 and the windward side of the exhaust fan 20. Specifically, in an alternative embodiment, the battery module 40 is located below the circuit board 31 and is spaced from the circuit board 31 to form the second air duct 102. The structural design can enable heat on the heating module 32 and the shielding cover 33 to be emitted from air flow of the first air duct 101; the heat on the circuit board 31 can be emitted from the air flow of the second air duct 102 to form an upper heat dissipation path and a lower heat dissipation path, so that the heat dissipation efficiency and the heat dissipation effect are better.

In an alternative more specific embodiment, the battery module 40 further includes a power supply battery 41 and a heat conductive case 42 covering the main body 130 and enclosing the battery accommodating cavity 400 with the main body 130, and the power supply battery 41 is fixed in the battery accommodating cavity 400. Preferably, the heat conductive case 42 may include a bottom plate 421 having a plate shape and being parallel to and attached to the main body 130, a top plate 422 having a plate shape and being parallel to and above the main body, and a side plate 423 connecting the top plate 422 and the bottom plate 421, wherein a bottom surface of the top plate 422 is in thermal contact with the power supply battery 41, and a top surface of the top plate 422 is spaced apart from the heat generating module 30 to form the second air duct 102. The additional heat-conducting shell 42 is provided to protect the power supply battery 41, so as to prevent the power supply battery 41 from contacting contaminants and moisture entering the accommodating cavity 100 through the air inlet 11, ensure the stability and reliability of the power supply battery 41, and ensure that heat can be smoothly conducted from the power supply battery 41 to the heat-conducting shell 42 to ensure the heat dissipation efficiency of the power supply battery 41.

More preferably, in order to avoid turbulence caused by the airflow entering the accommodating cavity 100 from the bottom plate 421 directly striking the side plate 423, and further avoid reducing the air intake efficiency, a guiding portion 420 inclined toward the air intake 11 is disposed at the junction of the vertically disposed side plate 423 and the horizontally disposed bottom plate 421. The design of the guiding portion 420 can guide the air flow entering the accommodating cavity 100 from the bottom plate 421 to flow into the second air duct 102 along the guiding portion 420 and the side plate 423 for thermal circulation, so as to avoid the air flow entering the accommodating cavity 100 from the bottom plate 421 to directly strike the side plate 423 and be reflected back to form turbulence with the newly entered air flow, thereby avoiding reducing the air inlet efficiency.

It should be noted that, in other modified embodiments, the front shell 14 further includes a top wall 142 connected to top edges of the plurality of side walls 140, and the top wall 142 is provided with a plurality of spare air outlets 1420; the decoration 15 is detachably disposed on the top wall 142 and covers the top wall 142 to form a plurality of spare air outlets 1420 on the top wall 142. When the power of the heating module 30 is increased and better heat dissipation efficiency is required, the user can remove the decoration 15 and increase the heat dissipation efficiency by using the spare air outlet 1420.

Of course, the design of auxiliary heat dissipation can achieve the technical effect of increasing the heat dissipation efficiency by using the spare air outlet 1420 without dismantling the decoration, for example, the decoration 15 is of a breathable net structure, so as to avoid that hot air cannot pass through the spare air outlet 1420.

More preferably, in one embodiment, the circuit board 31 is horizontally disposed in the accommodating cavity 100 and divides the accommodating cavity 100 into an upper space above the circuit board 31 and a lower space below the circuit board 31, respectively, and the edge of the circuit board 31 and the sidewall 140 are spaced apart from each other to form a gap 310 shown in the left side of fig. 2; the windward side of the exhaust fan 20 faces the edge region of the circuit board 31 and forms an air flow collecting region 200 therebetween. The air flow collecting area 200 is located in the upper space, and the first air duct 101 is located in the upper space and extends from the air inlet 11 to the air flow collecting area 200 along the first horizontal direction X; the second air duct 102 is located in the lower space, extends from the air inlet 11 to the gap 310 along the first horizontal direction X, and extends from the gap 310 to the air flow collecting area 200 located in the upper space; the first air duct 101 and the second air duct 102 are both connected to the windward side of the exhaust fan 20 via the air flow collecting area 200.

In this way, the air flow in the second air duct 102 can be guided to the edge of the circuit board 31 and then flows upward to the air flow collecting area 200 in the upper space through the gap 310 on the edge (such as the path marked by the left arrow in the housing case 10 in fig. 2), so that after the air flow reaches the air flow collecting area 200, the air flow enters the exhaust fan 20 upward from the side of the air flow collecting area 200 near the edge of the circuit board 31 (i.e. the left side of the drawing in fig. 2), and at the moment, the air flow in the first air duct 101 flows from the side away from the gap 310 (i.e. the right side of the drawing in fig. 2) to the air flow collecting area 200, and then enters the exhaust fan 20 upward from the side of the air flow collecting area 200 away from the gap 310 (such as the path marked by the right-left arrow in the housing case 10 in fig. 2). In this way, the air flow in the second air duct 102 cannot flow to the windward side of the exhaust fan 20 directly and be converged with the air flow in the first air duct 101 because the air flow is blocked by the circuit board 41 before reaching the gap 310, so that turbulence generated by mutual impact between the air flow in the first air duct 101 and the air flow in the second air duct 102 on the windward side of the exhaust fan 20 is reduced, and the two air flows occupy different areas on the left side and the right side of the exhaust fan 20 in a partitioning manner according to the above manner, thereby achieving higher air circulation efficiency and being beneficial to ensuring higher heat dissipation efficiency.
