[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a rapid heat dissipation device for an outdoor advertising machine includes a shell 1, the rear portion of the shell 1 is fixedly connected to a display 2, a cooling mechanism 3 is provided inside the shell 1, the cooling mechanism 3 includes an air pump 5, the top of the air pump 5 is fixedly connected to the bottom end of a connecting pipe 6, the top of the connecting pipe 6 is fixedly connected to an air chamber 9, the top of the air chamber 9 is fixedly connected to a conduit 4, the bottom of the air chamber 9 is fixedly connected to a vortex tube 7, the inner bottom of the vortex tube 7 is fixedly connected to a stopper 8, the bottom outer side of the vortex tube 7 is fixedly connected to the bottom of the shell 1, the top of the vortex tube 7 is fixedly connected to a guide block 10, the top of the guide block 10 is fixedly connected to the inner wall of the air chamber 9, and the top of the conduit 4 is fixedly connected to an air outlet 11.

[0023] In this embodiment, the inner side of the front portion of the housing 1 is fixedly connected to a limiting block 12 , and the rear portion of the limiting block 12 is rotatably connected to the front portion of the impeller 13 .

[0024] The airflow passing through the air port 11 can drive the impeller 13 to rotate, thereby guiding the airflow to the interior of the entire housing 1 .

[0025] In this embodiment, a T-shaped groove is formed at the rear of the limiting block 12 , and a T-shaped protrusion is formed at the rear of the impeller 13 .

[0026] The impeller 13 can rotate inside the limiting block 12 and will not fall due to the restriction of the limiting block 12 .

[0027] In this embodiment, a circular hole is opened at the rear of the impeller 13 , and a plurality of blades are arranged in the middle of the impeller 13 .

[0028] The airflow can pass through the circular holes of the impeller 13 and contact the blades thereof, and push the blades to make the impeller 13 rotate.

[0029] In this embodiment, the stopper 8 has a conical shape, and the maximum diameter of the stopper 8 is smaller than the diameter of the vortex tube 7 .

[0030] The block 8 can divert the airflow passing through, so that the airflow passing through the block 8 is discharged from the gap between the block 8 and the vortex tube 7 .

[0031] In this embodiment, a circular hole is opened on the top of the guide block 10 and penetrates to the bottom, and a plurality of inclined holes are opened on the outer side of the guide block 10 and penetrate to the inside.

[0032] The gas in the air chamber 9 can enter the interior of the vortex tube 7 through the inclined hole of the guide block 10 , and form a vortex flow in the interior of the vortex tube 7 under the guidance of the inclined hole.

[0033] In this embodiment, a circular hole is opened on the top of the air chamber 9, and a circular hole is opened on one side of the air chamber 9.

[0034] The airflow generated by the air pump 5 can enter the interior of the air chamber 9 through the circular hole on one side of the air chamber 9 and enter the vortex tube 7 through the guide block 10 .

[0035] It should be noted that the utility model is a fast heat dissipation device for an outdoor advertising machine. When in use, it can only use air for cooling, simplifying the structure of the heat dissipation device, and can spread cold air to the interior of the entire housing 1, so that the interior of the housing 1 is kept at a relatively low temperature to achieve the purpose of heat dissipation. The specific implementation method is to start the air pump 5, the air pump 5 generates airflow, and the airflow enters the air chamber 9 through the connecting pipe 6, and the pressure in the air chamber 9 rises;

[0036] The airflow in the air chamber 9 enters the vortex tube 7 through the oblique hole of the guide block 10 under the action of pressure. In the process of the airflow passing through the guide block 10, due to the guidance of the oblique hole of the guide block 10, the airflow will enter the vortex tube 7 in an inclined state, thereby forming a vortex inside the vortex tube 7. When the airflow in the vortex tube 7 is in vortex motion, the closer to the center, the greater the angular velocity of the vortex. Due to the difference in angular velocity, friction is generated between vortices at different levels. Since the angular velocity of the vortex at the center is the largest, the energy is transferred to the vortex at the outer layer with a lower angular velocity after friction.

[0037] The vortex at the center position loses energy, and the kinetic energy and speed are reduced, so that the temperature is reduced, and enters the conduit 4 through the hole at the top of the vortex tube 7. The vortex in the outer layer gains energy to increase the kinetic energy, converts part of the kinetic energy into heat energy, and is discharged from the hole at the bottom of the vortex tube 7; the cold air flow passes through the conduit 4 and is discharged through the air outlet 11, and blows the blades of the impeller 13 to rotate. While rotating, the impeller 13 guides and disperses the cold air flow to the inside of the shell 1, and is discharged through the exhaust hole of the shell 1. The cold air flow is dispersed in the inside of the shell 1, so that the temperature inside the shell 1 is reduced;

[0038] By providing a cooling mechanism 3, the heat dissipation device can generate a cold airflow only through air, and disperse the cold airflow through the impeller 13, so as to achieve the purpose of rapid heat dissipation, simplify the structure of the heat dissipation device, reduce the failure rate, facilitate maintenance, and optimize the heat dissipation effect.

[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
