Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1 to 4 shown, a heat-dissipating power amplifier for an audio player provided by the present utility model includes a power amplifier main body 1 and a housing 2. The power amplifier main body 1 is fixedly installed at the bottom of the inner wall of the housing 2.

A ventilation mechanism 4 is provided on the rear side of the front inner wall of the housing 2. Heat-carrying components 5 are fixedly connected to both the front side and the rear side of the inner wall of the housing 2.

[0022] As a technical optimization scheme of the present utility model, by providing the ventilation mechanism 4, the installation groove 41 can fix and limit the suction fan 42. By starting the suction fan 42, the air and heat inside the housing 2 can be accelerated and transferred to the outside. At the same time, the outside air can enter the inside of the housing 2 through the first ventilation opening 43 and the second ventilation opening 44, thereby improving the heat dissipation effect. At the same time, by arranging the suction fan 42 at the intersection of the front side and the right side of the power amplifier main body 1, the air conversion efficiency between the inside and the outside of the housing 2 can be improved.

[0023] Referring to Figure 2 and Figure 3The heat-carrying component 5 includes a fixing frame 51. An exhaust port 52 is provided on the inner wall of the fixing frame 51 close to the power amplifier body 1. A plurality of exhaust ports 52 are provided and are distributed at equal distances.

[0024] As a technical optimization scheme of the utility model, by setting up a heat-carrying component 5, part of the wind force that enters the shell 2 through the first vent 43 and the second vent 44 will enter the interior of the fixed frame 51, and part of the wind force that enters the interior of the fixed frame 51 can be directly blown to the inner wall of the heat dissipation fin 3 through the exhaust port 52, thereby playing a role in accelerating the removal of heat from the surface of the heat dissipation fin 3.

[0025] refer to Figure 2 and Figure 3 A heat spreader 6 is fixedly installed on the front and right sides of the power amplifier body 1. The side of the heat spreader 6 away from the power amplifier body 1 is fixedly connected to the side of the heat sink fin 3 close to the power amplifier body 1. The surface of the heat sink fin 3 is coated with graphene heat dissipation paint.

[0026] As a technical optimization scheme of the utility model, by setting up a heat spreader 6, the heat spreader 6 has a good heat absorption effect, can absorb the heat on the surface of the amplifier body 1 and conduct it to the surface of the heat sink fins 3, and by applying graphene heat dissipation paint on the surface of the heat sink fins 3, the heat radiation efficiency can be improved, the heat conduction performance can be enhanced, and its surface temperature can be reduced.

[0027] refer to Figure 2 and Figure 3 A wind guide plate 7 is fixedly connected to one side of the inner wall of the fixing frame 51 close to the power amplifier body 1 , and a plurality of wind guide plates 7 are provided and are distributed at equal distances.

[0028] As a technical optimization solution of the utility model, by setting the wind guide plate 7, the wind guide plate 7 can separate and guide the air entering the interior of the fixed frame 51 to the exhaust port 52, so that more wind can be blown to the heat dissipation fins 3, thereby accelerating the heat dissipation efficiency.

[0029] refer to Figure 2 and Figure 3 The bottom of the inner wall of the first ventilation port 43 and the second ventilation port 44 are both plugged with a dustproof net 8, the top of the dustproof net 8 passes through the shell 2 and is fixedly connected to a fixing plate 9, the dustproof net 8 is movably connected to the shell 2, and the bottom of the fixing plate 9 is fixedly connected to the top of the shell 2 by rivets.

[0030] As a technical optimization solution of the utility model, by providing a dustproof net 8 and a fixing plate 9, the dustproof net 8 can filter the air entering the interior of the shell 2 from the first ventilation port 43 and the second ventilation port 44, and by removing the fixing plate 9, the dustproof net 8 can be pulled away from the shell 2, thereby facilitating cleaning by the user.

[0031] Working principle and usage process of the present utility model: During use, the heat absorption effect of the heat pipe 6 is relatively good, which can absorb the heat on the surface of the power amplifier main body 1 and conduct it to the surface of the heat dissipation fins 3. By applying graphene heat dissipation coating on the surface of the heat dissipation fins 3, the heat radiation efficiency can be improved, the heat conduction performance can be enhanced, and the surface temperature can be reduced, with better heat dissipation effect. At the same time, by starting the suction fan 42, the air and heat inside the housing 2 can be accelerated and transferred to the outside, and the outside air can enter the inside of the housing 2 through the first ventilation opening 43 and the second ventilation opening 44. Part of the wind entering the inside of the housing 2 through the first ventilation opening 43 and the second ventilation opening 44 will enter the inside of the fixed frame 51. At this time, the air guide plate 7 can guide the separated air entering the inside of the fixed frame 51 to the air outlet 52, so that more wind can directly blow towards the heat dissipation fins 3, accelerating the heat dissipation efficiency. At the same time, by arranging the suction fan 42 at the intersection of the front side and the right side of the power amplifier main body 1, the air conversion efficiency between the inside and the outside of the housing 2 can be improved.

[0032] In summary: For this heat dissipation type power amplifier for an audio player, by setting the heat dissipation fins 3, the heat generated on the surface of the power amplifier main body 1 can be absorbed and dissipated into the air, solving the problem that after the existing power amplifier main body is used for a long time, a large amount of heat will be generated by the internal electronic components. If the heat is not dissipated in time, it is easy to cause the aging speed of the components to accelerate and the service life to be reduced, while the efficiency of discharging and dissipating the heat generated by the operation of the power amplifier main body by installing a fan inside is relatively low.
