[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0022] It should be noted that these and other accompanying drawings are merely examples and are not drawn to scale, and should not be used as a limitation on the scope of protection of this utility model.

[0023] Currently, camera cooling methods mainly include thermoelectric cooling, fan cooling, and water cooling, but each has encountered certain problems in field use. Thermoelectric cooling can lower the camera to a lower temperature, but when the temperature difference is too large, frost formation is likely to occur, and cooling resources are consumed in large quantities; fan cooling generally adds a cooling fan to the camera housing, mainly for cooling and protecting internal components, but it is prone to dust accumulation in the engineering field and also affects the precision protection of components; water cooling mainly uses external circulating two-way water cooling plates for cooling, but the contact area is limited, resulting in insufficient cooling effect.

[0024] This disclosure proposes a camera cooling structure that can achieve rapid and uniform heat dissipation using water-cooling and air-cooling components, while reducing dust pollution.

[0025] Reference Figures 1 to 4 As shown, the camera cooling structure 1 is used to cool the camera 2. The camera 2 includes a housing 21, a circuit board assembly 22 and a lens assembly 23. The housing 21 further includes an outer shell cover 211 and an inner shell cover 212, which together form an accommodating space. The circuit board assembly 22 is located in the accommodating space.

[0026] The cooling structure 1 includes a water-cooling component 3 and an air-cooling component 4. The water-cooling component 3 is located outside the housing 21 and includes water-cooling pipes 31, a water inlet 32, and a water outlet 33. Cooling water flows through the upper and lower, left and right cavities along the water-cooling pipes on the surface of the housing to provide overall cooling to the housing in a circumferential manner. Figure 2 The direction of the cooling water inlet is shown as A, and the direction of the cooling water outlet is shown as B.

[0027] like Figure 1 As shown, the water-cooling assembly 3 further includes an inner water-cooling shell 34 and an outer water-cooling shell 35. The inner water-cooling shell 34 is located outside the shell 21, and the water-cooling pipe 31 is disposed between the inner water-cooling shell 34 and the outer water-cooling shell 35. The water-cooling pipe is preferably S-shaped or serpentine in structure to achieve circulating cooling and to reduce the fluctuation and turbulence of cooling water on the shell surface, thereby improving the operating efficiency of the heat dissipation system.

[0028] The water-cooling assembly 3 also includes a rear water-cooling shell 36, which is used to seal the rear end of the outer water-cooling shell 35. It is equipped with an inlet adapter 361, an outlet adapter 362, and an air inlet 42, as well as a cavity 365 for exposing components such as the electrical interface 364. The inlet adapter 361 and outlet adapter 362 on the rear water-cooling shell 36 are respectively connected to the inlet 32 ​​and the outlet 33 to facilitate the delivery of cooling water.

[0029] The air-cooling assembly 4 utilizes cooling airflow for cooling and includes an air intake grille 41 and an air intake 42. The air intake grille 41 is located at the opening of the housing 21. Figure 1In the illustrated embodiment, the air intake grille 41 is located at the tail end of the inner shell cover plate 212 of the housing 21, at the tail opening of the housing 21. In other embodiments, the air intake grille 41 may also be a component independent of the housing 21, located at other openings of the housing. The air intake port 42 communicates with the air intake mesh grille 41 and is used to deliver cooling airflow to the air intake mesh grille 41. The air intake mesh grille is used to divert and filter the gas entering the housing, guiding the cooling gas entering through the air intake mesh grille 41 into the housing 21 to cool the camera interior.

[0030] The air inlet 42 on the rear water-cooled housing 36 is positioned opposite the air inlet grille 41 to deliver cooling gas to the air inlet grille 41. At this time, the water inlet 32, water outlet 33, and air inlet grille 41 are all located at the end of the housing 21 opposite to the lens assembly 23 of the camera.

[0031] The air intake grille 41 adopts a dense array of holes, which can increase the gas diversion and filtration effect. External cooling gas enters the air intake grille 41 from the air intake 42 through a protective device equipped with a filter such as filter cotton. Through the multi-hole guidance of the air intake grille 41, the cooling gas enters the camera evenly, realizing air circulation cooling inside the camera and providing heat dissipation for components such as circuit boards and CMOS.

[0032] To prevent external dust or debris from entering the camera, a filter device 43 is further provided between the air inlet 42 and the air inlet grille 41. This filter device may include components such as filter cotton, wet dust removal components, or fiber filter elements. This effectively prevents external dust or debris from entering the camera and thus avoids affecting the normal operation of internal components. In case of malfunction, the filter device can be replaced promptly, meeting the needs of rapid maintenance.

[0033] After the gas enters the camera, the camera housing 21 is also provided with an vent 25, such as... Figure 3 As shown, cooling gas M enters the camera interior and flows out through vent 25 in the venting direction N. Furthermore, the inner water-cooled housing 34 is provided with vent 341 and / or venting channel 342. The end of venting channel 342 terminates at the connection between the inner water-cooled housing 34 and the tail water-cooled housing 36. The tail water-cooled housing 36 is provided with a water-cooled tail housing vent 360 to assist the gas in the venting channel 342 in overflowing. Through the above design, the cooling gas, after passing through the camera's internal cavity and outer housing channels, overflows directly into the environment through the outer housing vent 25, vent 341, and venting channel 342.

[0034] In some embodiments, the air outlet channel 342 also carries the water cooling pipe 31, forming a heat dissipation channel structure that combines water cooling and air cooling, thereby effectively dissipating heat from the camera surface and interior.

[0035] The above-mentioned cooling structure has the following advantages:

[0036] (1) Combining water cooling and air cooling, the cooling water passes through the inner, outer and tail water cooling cavity structure. The cooling water continuously cools down through the water cooling pipeline circulation loop, effectively increasing the cooling water and the base area of ​​the shell. The gas, after passing through the camera cavity and the outer shell channel, directly overflows into the environment through the air hole. The two superimposed achieve the need for rapid and uniform heat dissipation, realizing the cooling of the camera's outer shell and the circulating cooling of internal components. The water cooling and air cooling structure is set on the surface of the camera shell, so there is no need to disassemble it and affect the camera performance.

[0037] (2) The S-shaped water cooling pipeline can reduce the fluctuation and turbulence of the cooling water on the shell surface, and further improve the heat dissipation efficiency;

[0038] (3) The multi-hole air intake grille delivers cooling airflow from the rear of the camera to achieve air circulation cooling inside the camera. At the same time, the grille structure protects the rear components of the camera from external impacts and provides a certain buffering effect.

[0039] (4) The air inlet is equipped with a filter device to effectively block external dust from entering the camera and prevent component contamination. The filter device is also easy to replace without disassembling and affecting the camera's performance, and has the advantage of easy maintenance.

[0040] (5) The cooling structure is small and simple, and can meet the requirements using general processing technology.
