[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides: a power amplifier housing which is convenient for heat dissipation, such as Figure 1-Figure 6As shown, it includes a protective shell 1, a mounting frame 7 is installed inside the protective shell 1, a heat dissipation inner frame 9 is inserted inside the mounting frame 7, and a plurality of heat dissipation plates 12 are symmetrically installed on both sides of the heat dissipation inner frame 9; a top cover 13 is installed on the top of the protective shell 1, a plurality of heat conduction plates 14 are installed on the top surface of the top cover 13, a heat conduction aluminum plate 17 is fitted on the lower part of the top cover 13, and a bellows 20 is arranged on the lower part of the heat conduction aluminum plate 17; a plurality of air guide blocks 18 are installed through the inside of the heat conduction aluminum plate 17, and each group of air guide blocks 18 passes through the top cover 13 and is inserted between two groups of heat conduction plates 14.

[0027] Preferably, a bottom filter 2 is installed through the bottom of the protective shell 1, a connecting slot 3 is opened through the rear side of the protective shell 1, two groups of control handles 4 are symmetrically installed on the front side of the protective shell 1, a plurality of groups of air exchange slots 5 are opened on the front side of the protective shell 1, and a plurality of groups of bases 6 are arranged at the bottom of the protective shell 1, so that the bottom of the protective shell 1 will not contact the outside, so that the bottom filter 2 opened at the bottom of the protective shell 1 can smoothly complete the air intake work, and during the air intake process, the bottom filter 2 can prevent debris from being drawn in from the outside of the protective shell 1, thereby improving the protection of the internal components of the power amplifier, and the connecting slot 3 opened on the rear side of the protective shell 1 enables the mounting frame 7 to be stably inserted , so that the internal components of the power amplifier can be stably installed inside the protective shell 1, and the internal components of the power amplifier are protected by the protective shell 1, the mounting frame 7 and the heat dissipation inner frame 9. The control handle 4 installed on the outside of the protective shell 1 enables the device as a whole to be better carried and used, and the air exchange slot 5 opened on the front side of the protective shell 1 enables the bellows 20 to select different directions to draw cold air in during operation, thereby completing the rapid cooling of the internal components of the power amplifier. A control module is installed on the front side of the protective shell 1, which is plugged in with the connection module of the card board 10 installed on the front side of the heat dissipation inner frame 9, so that the internal components of the power amplifier inside the heat dissipation inner frame 9 can be stably used.

[0028] Furthermore, a protective plate 8 is fixedly installed on the rear side of the mounting frame 7, and the rear end of the mounting frame 7 is fitted into the inner wall of the connecting slot 3 and plugged into the protective outer shell 1. A group of protective nets 11 are installed on the upper and lower sides of the heat dissipation inner frame 9. The protective plate 8 on the rear side of the mounting frame 7 improves the overall integrity of the protective outer shell 1 to avoid external influences on the internal electrical components of the protective outer shell 1. At the same time, the mounting frame 7 can also limit the heat dissipation inner frame 9, so that the upper, lower, left and right sides of the heat dissipation inner frame 9 do not contact the inner wall of the protective outer shell 1, thereby further improving the heat dissipation effect of the heat dissipation inner frame 9.

[0029] Furthermore, a group of mounting card plates 10 are respectively installed on the front and rear sides of the heat dissipation inner frame 9, and the heat dissipation inner frame 9 is plugged and installed with the mounting frame 7 through the two groups of mounting card plates 10. The mounting card plates 10 installed on the front and rear sides of the heat dissipation inner frame 9 can be removed to ensure the installation of electrical components. The two groups of mounting card plates 10 installed at the same time can be engaged with the mounting frame 7, so that the heat dissipation inner frame 9 can be better installed with the mounting frame 7 to complete the limitation of the heat dissipation inner frame 9. The protective nets 11 installed on the upper and lower sides of the heat dissipation inner frame 9 allow the external cold air to enter through the heat dissipation plate 12 and be directly passed through the heat dissipation inner frame 9 when it is drawn out by the bellows 20, so that the electrical components inside the heat dissipation inner frame 9 can be better cooled. At the same time, the heat dissipation plates 12 installed on the left and right sides of the heat dissipation inner frame 9 can enhance the heat dissipation effect of the heat dissipation inner frame 9, so that the internal temperature of the heat dissipation inner frame 9 is exported by the heat dissipation plates 12, and the hot air is exchanged out through the air intake of the air exchange slot 5 and the bottom filter 2.

[0030] It is worth mentioning that a plurality of through holes 15 are provided between the top cover 13 and the two adjacent groups of heat conducting plates 14. The plug plates 16 are symmetrically installed on the lower surface of the top cover 13. The plug plates 16 are plugged and installed in contact with the inner wall of the protective shell 1. The top cover 13 seals the top opening of the protective shell 1, and limits the heat conducting plates 14 and the heat conducting aluminum plates 17 through the top cover 13 to ensure that the heat conducting aluminum plates 17 can quickly absorb heat and export the heat to the inside of the heat conducting plates 14. The through holes 15 opened inside the top cover 13 enable the air guide blocks 18 to extend out, so that the hot air inside the protective shell 1 can be exported after the bellows 20 works, and the air flow inside the heat conducting plates 14 can be quickly driven, thereby completing the rapid cooling of the heat conducting plates 14. The plug plates 16 are installed at the bottom of the top cover 13 so that the top cover 13 can be stably plugged and matched with the protective shell 1, so that the top cover 13 and the protective shell 1 form a whole to complete the protection of the electrical components.

[0031] Specifically, each group of air guide blocks 18 extends from the inside of the corresponding through hole 15, and two groups of inclined surfaces are provided on the upper surface of the air guide block 18. The air guide block 18 is a hollow structure, and both groups of inclined surfaces are provided with wind tunnels 19. The air guide block 18, as a hollow structure, is used in conjunction with the bellows 20 and the heat-conducting aluminum plate 17. The bellows 20 draws out wind and sends it out through the air guide block 18 during operation. The wind tunnels 19 provided on both sides of the air guide block 18 allow the gas to flow inside two adjacent groups of heat-conducting plates 14 to quickly dissipate the heat of the heat-conducting plates 14, thereby completing the heat dissipation treatment of the electrical components inside the heat-dissipating inner frame 9.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
