An inner support plate 251 is fixedly installed on the inner wall of the cylinder 25, and an impeller 252 is rotatably connected to the inner wall of the inner support plate 251. The output shaft of the driving motor 253 extends into the inner cavity of the circulation square cylinder 25 and is fixedly connected to the center of the top of the impeller 252. The driving motor 253 is controlled to drive the impeller 252 to rotate in the inner support plate 251, which can absorb air from the uniform wind mesh plate 211 of the hollow operating table 23, and then output air from the uniform wind mesh plate 211 of the hollow base 21, and at the same time, the air in the inner cavity of the closed heat dissipation mechanism 2 circulates through the inner cavity of the heat exchange copper tube 24. The internal circulating air will exchange heat with the outside air through the heat exchange copper tube 24, thereby realizing the function of closed heat dissipation of the visual image processing host inside the closed frame 22. By arranging the driving motor 253 at the top of the circulation square cylinder 25, the problem of the heat generated by the driving motor 253 affecting the heat dissipation is avoided.

[0027] As an implementation method in this embodiment, Figure 3 , Figure 4, Figure 5 As shown, semiconductor refrigerators 255 are fixedly installed on both sides of the circulation square cylinder 25, a guide inner frame 254 is fixedly installed between the front and back sides of the inner wall of the circulation square cylinder 25, a circular mesh seat 256 is fixedly installed on the top of the guide inner frame 254, a temperature sensor 257 is fixedly installed on the top of the circular mesh seat 256, and the temperature sensor 257 is connected to the semiconductor refrigerator 255 through an external controller.

The temperature sensor 257 can monitor the temperature of the internal circulating air. When the temperature is higher than the preset value, the semiconductor refrigerator 255 is controlled to work through the external controller.

Through the design of the magnetic block 223, the closed door panel 221 can be magnetically attracted to the front of the closed frame 22, which is convenient for users to disassemble and assemble the closed door panel 221 and to maintain the visual image processing host in the inner cavity of the closed frame 22. The rubber inner frame 222 is used to seal the connection between the closed door panel 221 and the closed frame 22. Through the design of the mesh host support platform 224, the components included in the visual image processing host can be classified and supported, which is convenient for sorting and improves the heat dissipation effect.

[0029] like Figure 8As shown, a visual processing system is installed in the visual image processing host, and the visual processing system mainly consists of four parts: image acquisition, image encoding, image processing and image display. The RV1126 chip controls the IMX415 chip to acquire images, sends the image data to the system for processing, and enhances the image through median filtering, exposure gain, and image sharpening. This step is completed on the external memory DDR4, and finally the processed image is transmitted to the LCD screen 11.

[0030] The video acquisition module consists of two parts, the external IMX415 photosensitive chip and the VI channel of the embedded chip RV1126.

[0031] Video acquisition is mainly completed by an external IMX415 camera. As a standard CMOS sensor, its photosensitive array can reach 3864*2228, and its effective pixels can reach 3864*2192.

[0033] Working principle: The visual image processing host is pre-installed on the bottom uniform wind mesh plate 211 and the top of the mesh host support platform 224. Through the operation of the visual image processing host, the image can be processed, and the processing result is displayed through the LCD screen 11. During the operation of the visual image processing host, the drive motor 253 is controlled to drive the impeller 252 to rotate, absorb air from the uniform wind mesh plate 211 of the hollow operating table 23, and then output air from the uniform wind mesh plate 211 of the hollow base 21, so that the air in the inner cavity of the closed heat dissipation mechanism 2 circulates through the inner cavity of the heat exchange copper tube 24, and the visual image processing host inside the closed frame 22 is closed for heat dissipation.

[0034] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
