Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cameras, and in particular to a high-temperature resistant camera. Background Technology
[0002] In high-temperature environments (such as inside nuclear reactors or near metallurgical furnaces), conventional camera equipment often cannot operate stably for extended periods. High temperatures can cause the internal electronic components of the camera to overheat, leading to performance degradation, image distortion, or even equipment damage.
[0003] Currently, camera protection for high-temperature environments mainly employs a single heat insulation layer or a simple air-cooling / water-cooling system. For example, some devices use heat-insulating shells or high-temperature resistant materials to block external heat, but these methods have limited heat dissipation efficiency and are insufficient to meet the needs of continuous monitoring in high-temperature environments. Other solutions use forced air cooling or liquid cooling, but these typically only have a single-layer cooling channel, resulting in insufficient cooling effect and problems such as uneven airflow distribution and short heat dissipation paths, making it impossible to achieve efficient heat dissipation over a long period of time.
[0004] In summary, existing cameras have significant shortcomings in heat insulation and heat dissipation design, and cannot meet the requirements for long-term continuous operation in high-temperature environments. Utility Model Content

[0023] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict.
[0024] As Figure 1 shown, the embodiment of the present application provides a high-temperature-resistant camera, which comprises a shell assembly 10 and a camera body 20 arranged inside the shell assembly 10, and the shell assembly 10 comprises a first shell 11, a second shell 12 and a third shell 13 arranged in sequence from inside to outside. The first shell 11 preferably uses a material with good thermal and electrical insulation properties, such as ceramic or carbon fiber reinforced plastic, etc.; the second shell 12 and the third shell 13 need to have both heat insulation and certain structural strength, and preferably use metal materials such as aluminum alloy or stainless steel.
[0025] Among them, the first cooling channel 110 is arranged between the first shell 11 and the second shell 12, and the second cooling channel 120 is arranged between the second shell 12 and the third shell 13. The camera body 20 has a camera end as a top end and another end as a bottom end. The bottom end of the first cooling channel 110 is connected to a cold air flow, and the top end of the first cooling channel 110 is connected to the top end of the second cooling channel 120. The bottom end of the second cooling channel 120 is connected to the outside through an exhaust pipe (not shown in the figure).
[0026] Through the multi-structure design of the first shell 11 to the third shell 13, an effective physical heat shield is formed to protect the internal camera body 20 from the external high-temperature environment. At the same time, the first cooling channel 110 and the second cooling channel 120 are used in series. The cold air flow is introduced from the bottom end of the first cooling channel 110, enters the second cooling channel 120 at the top end, and is then discharged from the bottom end of the second cooling channel 120 through the exhaust pipe, forming two layers of cooling channels inside and outside. The high-temperature isolation and high-efficiency heat dissipation of the camera body 20 are realized, and the long-term stable operation of the camera body 20 in a high-temperature environment is ensured.
[0027] Further, the high-temperature-resistant camera further comprises a vortex tube 30, a cold end outlet of the vortex tube 30 being communicated with a bottom end of the first cooling channel 110. By injecting compressed air into the vortex tube 30, the high-speed airflow is separated into cold and hot airflows by the action of the vortex tube 30, so as to obtain the cold airflow. The vortex tube 30 has no mechanical moving parts inside, which means that it almost needs no maintenance when running, reduces the failure rate and prolongs the service life of the equipment; and the structure of the vortex tube is relatively simple and compact, and is easy to integrate into various equipment, especially in space-limited application scenarios.
[0028] Further, the first shell 11 comprises a flow equalizer 111 arranged at the bottom end, an inlet of the flow equalizer 111 being communicated with the cold end outlet of the vortex tube 30, and a plurality of outlets of the flow equalizer 111 being uniformly arranged around the flow equalizer 111 and communicated with the first cooling channel 110. The cold airflow generated by the vortex tube 30 can be uniformly distributed around the first shell 11 through the flow equalizer 111, so as to avoid the local overheating.
[0029] As shown in FIG. 1, in the embodiment, the shell assembly 10 further comprises a fourth shell 14 arranged at the outermost layer. The fourth shell 14 is used as the outermost layer, and is preferably made of a high-temperature-resistant and corrosion-resistant alloy material, such as titanium alloy or special stainless steel. Figure 1 The fourth shell 14 and the third shell 13 are provided with a thermal insulation layer 130 to isolate the low-temperature environment inside from the high-temperature environment outside, reduce heat exchange, and maintain a stable low-temperature state inside the shell assembly 10. The material of the thermal insulation layer 130 can be polyurethane foam, glass fiber, vacuum insulation board or aerogel according to the specific use environment, which is not limited here.
[0030] In the embodiment, the fourth shell 14 comprises a top cover 141, a side cylinder 142 and a bottom cover 143, and a gap is left between the first shell 11 and the top cover 141 and communicated with the first cooling channel 110. The cold airflow of the first cooling channel 110 is introduced into the top of the first shell 11 through the gap, so that the top end of the camera body 20 can also obtain good cooling effect, and the camera body 20 is ensured to be protected by high-temperature resistance in all directions.
[0031] In the embodiment, the second shell 12 is a hollow sleeve, and a gap is left between the top end of the second shell 12 and the top cover 141, so that the first cooling channel 110 and the second cooling channel 120 are communicated. Of course, the top end of the second shell 12 directly contacts the top cover 141, and a plurality of through holes can also be arranged on the top side wall of the second shell 12 to meet the communication requirement, but the scheme of leaving a gap directly can provide greater gas flux.
[0032] Furthermore, the bottom of the second housing 12 is longer than that of the first housing 11, and an accommodating chamber is formed between the bottom wall of the first housing 11, the second housing 12 and the bottom cover 143, thereby leaving installation space for the cold end outlet of the vortex tube 30, the exhaust pipe and the cable of the camera body 20.
[0033] like Figure 1 As shown, in this embodiment, an annular plate 121 is fixed between the bottom end of the second housing 12 and the bottom end of the third housing 13. The annular plate 121 has several evenly distributed through holes. A gap is left between the annular plate 121 and the bottom cover 143. The accommodating chamber is connected to the bottom end of the second cooling channel 120 through the several through holes on the annular plate 121. The exhaust pipe is connected to the accommodating chamber. Cold air enters from the bottom end of the first cooling channel 110, enters the second cooling channel 120 at the top, and then passes sequentially from the bottom end of the second cooling channel 120 through the annular plate 121, the gap between the annular plate 121 and the bottom cover 143, and the accommodating chamber. Finally, it is discharged through the exhaust pipe. This forms two layers of cooling channels on the side wall and bottom of the camera body 20, achieving high-temperature isolation and efficient heat dissipation for the camera body 20, ensuring stable operation of the camera body 20 in high-temperature environments. The bottom of the second housing 12 and the annular plate 121 are both separated from the bottom cover 143 by gaps, which avoids heat exchange caused by direct contact and reduces internal temperature accumulation.
[0034] Furthermore, the top cover 141 has an annular groove, into which the top of the third housing 13 engages. This design simplifies the assembly process, making the connection between the housings more direct and faster, while ensuring the reliability of the connection. The joints between the top cover 141 and the side cylinder 142, as well as the joints between the top cover 141 and the bottom cover 143, are sealed with sealant to ensure good sealing performance even under extreme temperatures and prevent failure due to temperature changes.
