[0038] The cooling mechanism 4 includes a centralized flow guide frame 40, which is mounted on the circuit board 2. Two square openings are provided at the bottom of the centralized flow guide frame 40, and a heat sink 44 is provided in the square openings. One end of the heat sink 44 contacts the heating element on the circuit board 2. The centralized flow guide frame 40 can effectively gather and guide the airflow to improve the heat dissipation efficiency. The square opening at the bottom cooperates with the heat sink 44, so that the heat sink 44 is in close contact with the heating element, accelerating heat conduction, ensuring that the heat generated by the heating element can be quickly taken away, and ensuring the stable operation of the circuit board 2.

[0039] An air duct cooperating with the heat sink 44 is provided in the inner cavity of the centralized guide frame 40, and the first air inlet hood 41 and the closing door 43 are both connected to the center of the air duct. This air duct design enables the cold air entering from the first air inlet hood 41 to flow accurately and efficiently to the heat sink 44, thereby achieving synchronous cooling of the heating element and the pulse generator 3. The airflow converges at the center of the air duct, ensuring the uniformity of the airflow distribution and improving the overall heat dissipation effect.

[0040] Furthermore, the inner cavity of the first air inlet hood 41 is provided with a plurality of guide plates arranged in an annular inclined shape; the annular inclined guide plates can change the direction of the airflow, so that the airflow entering the first air inlet hood 41 forms a vortex shape, thereby increasing the contact area and contact time with the pulse generator 3, and enhancing the heat dissipation effect on the pulse generator 3. Compared with conventional direct blowing airflow, the heat dissipation efficiency is significantly improved.

[0041] Furthermore, a controller 431 is hinged on the side wall of the closing door 43, and the other end of the controller 431 is hingedly mounted on an electric push rod 432, and the electric push rod 432 is mounted on the circuit board 2; through the cooperation of the controller 431 and the electric push rod 432, the opening and closing angle of the closing door 43 can be accurately controlled, and the air intake volume and air intake path can be flexibly adjusted according to the temperature of the pulse generator 3 and the heating elements on the circuit board 2, thereby realizing intelligent and refined heat dissipation control and improving the adaptability and energy saving of the heat dissipation system.

[0043] Furthermore, one end of the silencer nozzle 25 is connected to the airflow duct 24, and a plurality of exhaust ports are provided on the silencer nozzle 25. The cross-section of the exhaust ports is hexagonal, and a plurality of rubber noise reduction plates 251 are provided at one end of the silencer nozzle 25; the hexagonal exhaust ports make the airflow smoother and reduce turbulence, and cooperate with the internal arc-shaped diversion groove to further reduce the degree of airflow turbulence; the rubber noise reduction plates 251 can effectively absorb and block the noise generated when the airflow is discharged, greatly reducing the equipment operation noise, and meeting the use scenarios with requirements for working environment noise.

[0044] Furthermore, a carrying handle 11 and a display screen 12 for displaying the internal temperature environment are provided on the top of the device housing 1. Two temperature control units are connected to the other side of the display screen 12 through wires, and the two temperature control units are respectively fitted with the heating element on the circuit board 2 and the pulse generator 3; the carrying handle 11 facilitates the transportation of the equipment and improves the convenience of moving the equipment; the display screen 12 and the temperature control unit provide real-time feedback on the temperature of the heating element and the pulse generator 3, so that the user can understand the internal temperature status of the equipment at any time, which is convenient for timely taking heat dissipation measures to ensure safe and stable operation of the equipment.

[0045] Working principle:

[0046] The overall heat dissipation process is as follows: when the device is running, the drive motor 7 is started, and the drive motor 7 drives the turbine blades 6. The rotation of the turbine blades 6 transports the gas in the centralized guide frame 40 to the outside of the pipeline 101 and the device housing 1 through the air channel 5, so as to achieve the effect of reducing the internal temperature of the device housing 1;

[0047] First, the internal gas flow is coordinated with the air duct set in the centralized guide frame 40. When the air flow flows through the air duct, since one side of the heat sink 44 is in contact with the surface of the heating element on the circuit board 2, the heat will be quickly transferred to the heat sink 44 when it is generated. At this time, cold air can enter the centralized guide frame 40 from the first air inlet cover 41 and the second air inlet cover 42 respectively to cool the surface of the heat sink 44, and the synchronous cooling effect of the heating element and the pulse generator 3 can be quickly achieved;

[0048] During the process, the controller 431 can be used to control the start of the extension and retraction of the electric push rod 432, and the extension and retraction of the electric push rod 432 pulls the closing door 43 to open and close the second air intake hood 42 in two ways to achieve a centralized cooling mode with different effects on the centralized guide frame 40 and the pulse generator 3;

[0049] In the open mode of the closed door 43: the open mode can be divided into a fully open and half-open mode, the airflow will be divided into two parts and enter the centralized guide frame 40 at the same time. First, when the airflow enters the first air inlet hood 41, the pulse generator 3 is cooled. At this time, the airflow temperature rises, and when it flows into the centralized guide frame 40, the cooling effect on the heat sink 44 is reduced. Therefore, the speed and amount of the airflow flowing into the first air inlet hood 41 can be reduced by opening the opening and closing range of the closed door 43, thereby improving the cooling effect on the heat sink 44. This mode is mainly used to improve the cooling efficiency of the heat sink 44 when the temperature of the heat sink 44 is too high.

[0050] When the closed door 43 is in the closed mode: when the closed door 43 is in contact with the air inlet of the second air inlet hood 42, the airflow cannot enter the inner cavity of the centralized guide frame 40 through the second air inlet hood 42. At this time, the airflow can only enter the inner cavity of the centralized guide frame 40 through the first air inlet hood 41. At this time, the inflow of the airflow at the inlet of the first air inlet hood 41 is the highest. Combined with the guide function of the multiple guide plates arranged in the first air inlet hood 41, the airflow is in a vortex circulation state when entering the first air inlet hood 41. The airflow in the vortex circulation state can form a circulation on the outer wall of the pulse generator 3, and the effect of the circulation can form a The heat dissipation effect of wrapping the outer side of the pulse generator 3 can be achieved, and the temperature can be lowered more efficiently than the traditional one-way gas direct blowing; this mode is mainly used when the temperature of the pulse generator 3 is too high and the pulse generator 3 needs to be cooled in time. In this mode, the total amount of airflow output by the turbine blades 6 driven by the two drive motors 7 enters through the first air intake hood 41, that is, in this mode, the airflow inhaled by the two turbine blades 6 can act on the surface of the pulse generator 3 at the same time, and the effect of cooling the pulse generator 3 is better than that of the airflow inhaled by a single turbine blade 6;

[0051] Second, after being discharged through the pipe 101, the airflow enters the hose and is transported to the airflow duct 24 through the hose. The airflow enters the silencer nozzle 25 through the airflow duct 24 and is then discharged. The airflow is diverted in the silencer nozzle 25, and the multiple streams of air after diversion are discharged from the exhaust port. The airflow passes through the exhaust port with a hexagonal guide structure. Compared with the traditional circular or square port, the airflow can be discharged more smoothly. Combined with the setting of the internal arc-shaped diversion groove, turbulence can be reduced during airflow circulation to avoid sharp turns, protrusions or narrow areas in the air duct. At the same time, the structure can effectively increase the noise level during airflow output.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
