Description

Technical Field

[0001] This utility model belongs to the field of high-temperature imaging technology, specifically, it relates to a water jacket for a high-temperature melting furnace endoscope camera. Background Technology

[0002] In industries such as glass, ceramics, and metallurgy, high-temperature melting furnaces are key production equipment. The temperature inside the melting furnace is usually very high; for example, the temperature of a glass melting furnace can reach 1500-1600℃. During the production process, it is necessary to monitor the situation inside the melting furnace in real time, including the melting state of the materials, the shape and position of the flames, and the erosion of the furnace walls. Traditional monitoring methods are difficult to meet the requirements because monitoring equipment directly exposed to high-temperature environments is easily damaged.

[0003] Chinese patent CN115225794A discloses a camera device capable of operating in high-temperature environments, comprising an outer casing and a camera body. The camera body is housed within the outer casing, with a lens through-hole on one end face of the outer casing. The camera lens of the camera body faces the lens through-hole. The other end of the outer casing is fixed to and connected to one end of a hollow steel pipe. By allowing cooling circulating water to flow within the outer casing, heat can be effectively carried away, lowering the temperature of the environment in which the camera body is located and maintaining it at a relatively low temperature, thereby extending the service life of the camera body. This utilizes the high specific heat capacity of water to achieve a good heat dissipation and cooling effect. However, this device may still have insufficient cooling effect when facing extreme high-temperature environments. For example, inside a glass melting furnace, the local temperature may rise abnormally. When the temperature far exceeds the design limit, the cooling circulating water and low-temperature compressed air may not be able to remove enough heat in time, resulting in the camera body temperature becoming too high, affecting its normal operation and service life.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water jacket for a high-temperature melting furnace endoscope camera, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A water jacket for a high-temperature melting furnace endoscope camera includes: an outer shell and a camera. The camera is located inside a fixed shell, which is connected to the inside of the outer shell by a fixing plate. A water-cooling pipe is connected to the surface of the fixed shell. One end of the water-cooling pipe is connected to a connecting pipe, and the other end of the connecting pipe passes through the outer shell and is connected to an external water source. The side wall of the water-cooling pipe is provided with heat dissipation fins. An opening is provided on the side wall of the outer shell at the heat dissipation fins, and a heat dissipation box is connected to the opening.

[0008] Optionally, the water-cooling pipe is spiral-shaped and wound around the surface of the fixed shell.

[0009] Optionally, a connecting piece is connected to the top of the heat dissipation fins, and the sidewall of the connecting piece is connected to the inner wall of the outer casing.

[0010] Optionally, the heat dissipation box is provided with multiple baffles inside, which form a tortuous heat dissipation channel inside the heat dissipation box.

[0011] Optionally, the heat sink has multiple heat dissipation holes at both the front and rear ends, and the heat sink is sealed to the opening of the outer shell side wall.

[0012] Optionally, the housing has a window on the side wall facing the camera.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] The comprehensive heat dissipation system, consisting of a water-cooling circulation system, heat dissipation fins, and heat dissipation box, effectively copes with the high-temperature effects of the high-temperature melting furnace environment. Even when the temperature around the melting furnace is extremely high, the ambient temperature of the camera can be controlled within a suitable range. This avoids problems such as performance degradation or damage to the internal electronic components of the camera due to high temperature, or image distortion or blurring. It ensures that the camera can stably and clearly acquire images inside the melting furnace, providing accurate and reliable data for production monitoring.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this embodiment provides a water jacket for a high-temperature furnace endoscope camera, including: a housing 1 and a camera 3. The camera 3 is located inside a fixed housing 7. The fixed housing 7 is connected to the inside of the housing 1 by a fixing piece 8. A water-cooling pipe 6 is connected to the surface of the fixed housing 7. One end of the water-cooling pipe 6 is connected to a connecting pipe 5. The other end of the connecting pipe 5 passes through the housing 1 and is connected to an external water source. The side wall of the water-cooling pipe 6 is provided with heat dissipation fins 10. An opening is provided on the side wall of the housing 1 at the heat dissipation fins 10. A heat dissipation box 4 is connected to the opening.

[0027] The water jacket mainly consists of an outer shell 1 and a camera 3. The camera 3 is housed inside a fixed shell 7. This double-shell structure provides multi-layered protection for the camera 3. The fixed shell 7 is connected to the interior of the outer shell 1 via a fixing plate 8, forming a relatively stable overall structure. This ensures that the camera 3 can maintain a relatively fixed position in the high-temperature furnace environment where there may be some impact or vibration, which is beneficial for obtaining stable and clear images. A water-cooling pipe 6 is connected to the surface of the fixed shell 7. One end of the pipe is connected to a connecting pipe 5, and the other end of the connecting pipe 5 passes through the outer shell 1 and connects to an external water source. This forms a complete water-cooling circulation path. Water from the external water source flows into the water-cooling pipe 6, absorbs the heat emitted by the fixed shell 7 and the camera 3 through heat transfer, and then the water carrying away the heat flows out back to the external cooling system or other heat dissipation areas. After cooling, the water is recirculated into the water-cooling pipe 6 to continuously cool the camera 3, ensuring its normal operation in high-temperature environments. The heat dissipation fins 10 increase the contact area between the water-cooling pipe 6 and the surrounding air, improving heat exchange efficiency. The side wall of the outer shell 1 has an opening at the heat dissipation fins 10, and a heat dissipation box 4 is connected to this opening. The function of the heat dissipation box 4 is to further optimize the heat dissipation environment. It can provide a relatively closed space for the heat dissipation fins 10 that is conducive to airflow, so that heat can be dissipated to the surrounding environment more quickly. For example, a fan or other device can be installed in the heat dissipation box 4 to force airflow over the heat dissipation fins 10 and accelerate heat dissipation. Even when the ambient temperature around the high-temperature furnace is high, it can enhance the heat dissipation capacity of the entire water cooling system, ensuring that the camera 3 is always within a suitable operating temperature range.

[0028] In this embodiment, the water-cooling pipe 6 is spiral and wrapped around the surface of the fixed shell 7. The top of the heat dissipation fin 10 is connected to the connecting piece 9. The side wall of the connecting piece 9 is connected to the inner wall of the outer shell 1. The heat dissipation box 4 is provided with multiple baffles 11. The multiple baffles 11 form a tortuous heat dissipation channel inside the heat dissipation box 4. Multiple heat dissipation holes are opened at both the front and rear ends of the heat dissipation box 4. The heat dissipation box 4 is sealed to the opening of the side wall of the outer shell 1. A window 2 is opened on the side wall of the outer shell 1 facing the camera 3.

[0029] The water-cooling pipe 6 adopts a spiral design and is tightly wound around the surface of the fixed shell 7, greatly increasing the contact area between the water-cooling pipe 6 and the fixed shell 7. Compared with a straight arrangement, the spiral structure can more comprehensively cover the fixed shell 7, allowing heat to be transferred more evenly and efficiently from all parts of the fixed shell 7 to the water-cooling pipe 6. For example, when the fixed shell 7 is heated as a whole due to its proximity to a high-temperature furnace, the spiral water-cooling pipe 6 can absorb heat over a larger area, making the temperature distribution of the fixed shell 7 and the internal camera 3 more uniform, avoiding local overheating, and thus better ensuring that the camera 3 is in a suitable operating temperature environment. The connecting piece 9 at the top of the heat dissipation fin 10... Connecting the heat dissipation fins 10 to the inner wall of the outer casing 1 stabilizes their position. During operation, the water jacket is affected by vibrations and thermal expansion and contraction in the furnace environment. The connecting piece 9 ensures that the heat dissipation fins 10 remain in the correct position, tightly engaging with the water cooling pipes 6 to stably perform their heat dissipation function. Simultaneously, connecting to the inner wall of the outer casing 1 helps to better conduct heat to the outer casing 1, which then further dissipates heat to the surrounding environment, forming a continuous heat transfer path from the fixed casing 7, water cooling pipes 6, heat dissipation fins 10 to the outer casing 1, improving overall heat dissipation efficiency. Multiple baffles 11 are installed inside the heat sink 4. 1. The interconnected structures create a tortuous heat dissipation channel. When hot air flows within the heat sink 4, the tortuous channel extends the airflow path, allowing for more sufficient contact time between the air and the heat dissipation fins 10. This enables the hot air to more fully absorb heat from the heat dissipation fins 10, thereby improving the heat dissipation effect. Furthermore, this design allows for a more stable airflow within the heat sink 4, preventing air "short-circuiting" (i.e., rapid outflow without sufficient heat dissipation). This ensures that the heat dissipation fins 10 in all areas of the heat sink 4 are effectively utilized, improving the uniformity and efficiency of heat dissipation throughout the entire heat sink 4. Multiple [unclear text - possibly referring to a specific design element or feature] at both ends of the heat sink 4... The heat dissipation holes are important channels for heat exchange. The heat dissipation holes at the front end allow relatively low-temperature air from the outside to enter the heat dissipation box 4, while the heat dissipation holes at the rear end facilitate the exhaust of hot air that has absorbed heat into the surrounding environment. Through the continuous inflow and outflow of air, a continuous air circulation is formed, which removes the heat inside the heat dissipation box 4 and maintains a low temperature environment inside the heat dissipation box 4. This ensures that the heat dissipation fins 10 can continuously and effectively transfer heat to the air, further enhancing the heat dissipation capacity of the entire water jacket and helping to cope with the high temperature challenges brought by the high-temperature furnace. The outer shell 1 has a window 2 on the side wall facing the camera 3. Its main purpose is to provide the necessary optical path for the shooting function of the camera 3.

[0030] Working principle:

[0031] The high-temperature melting furnace releases a large amount of heat into the water jacket. The camera 3, located inside the fixed housing 7, and the housing itself will experience a temperature increase due to heat conduction. At this point, the water-cooling circulation system connected to an external water source begins to function. Water from the external source flows through the connecting pipe 5 into the water-cooling pipe 6, which is spirally wound around the surface of the fixed housing 7. The spiral design provides a large contact area between the water-cooling pipe 6 and the fixed housing 7, allowing heat to be transferred evenly and efficiently from all parts of the fixed housing 7 to the water inside the water-cooling pipe 6. The water absorbs heat and its temperature rises, forming a heat transfer path from the fixed housing 7 to the water-cooling pipe 6, achieving initial cooling of the fixed housing 7 and the camera 3. The water, having absorbed heat, flows out of the water jacket through the connecting pipe 5 and returns to the external cooling system for further cooling and other processing. The treated water then recirculates into the water-cooling pipe 6. This continuous cycle forms a constant water-cooling circulation path, continuously removing heat from the camera 3 and the fixed housing 7, ensuring they remain within a suitable temperature range and allowing the camera 3 to operate normally in high-temperature environments.

[0032] While the water-cooling pipe 6 absorbs heat, the heat dissipation fins 10 on its sidewalls also participate in the heat dissipation process. The heat dissipation fins 10 can increase the contact area between the water-cooling pipe 6 and the surrounding air, so that the heat carried by the water in the water-cooling pipe 6 can be transferred to the surrounding air more efficiently. The top of the heat dissipation fins 10 is connected to the inner wall of the outer shell 1 through the connecting piece 9. On the one hand, when the water jacket is affected by the vibration of the melting furnace environment, thermal expansion and contraction, etc., the connecting piece 9 can stabilize the position of the heat dissipation fins 10, so that it fits tightly with the water-cooling pipe 6, ensuring that the heat is continuously and stably transferred from the water-cooling pipe 6 to the heat dissipation fins 10. On the other hand, the heat absorbed by the heat dissipation fins 10 can be conducted to the outer shell 1 through the connecting piece 9, and then dissipated to a wider surrounding environment with the help of the outer shell 1, forming a continuous heat transfer link from the fixed shell 7, water-cooling pipe 6, heat dissipation fins 10 to the outer shell 1, further improving the overall heat dissipation efficiency.

[0033] The outer casing 1 has openings on its sidewalls at the heat dissipation fins 10, connecting to a heat sink 4. The heat sink 4 contains multiple baffles 11 that work together to create a tortuous heat dissipation channel. When the heat dissipation fins 10 transfer heat to the surrounding air, the hot air enters the tortuous channel within the heat sink 4. Because the channel is tortuous, the airflow path is extended, allowing for more contact time with the heat dissipation fins 10, thus absorbing heat more effectively and improving heat dissipation. Furthermore, this tortuous channel design creates a relatively stable airflow within the heat sink 4, preventing hot air from quickly escaping before sufficient cooling (i.e., air "short-circuiting"), ensuring adequate heat dissipation in all areas of the heat sink 4. The fins 10 are all effectively utilized, improving the heat dissipation uniformity and efficiency of the entire heat sink 4. The multiple heat dissipation holes at the front and rear ends of the heat sink 4 are key channels for heat exchange. The heat dissipation holes at the front end allow relatively low-temperature air from the outside to enter the heat sink 4. After passing through the tortuous channels and fully exchanging heat with the heat dissipation fins 10, the incoming cold air becomes hot air. The heat dissipation holes at the rear end facilitate the exhaust of this hot air into the surrounding environment. With the air constantly entering from the front and exiting from the rear, a continuous air circulation is formed in the heat sink 4, carrying away the heat inside the heat sink 4 and maintaining a low temperature environment inside the heat sink 4. This ensures that the heat dissipation fins 10 can continuously and effectively transfer heat to the air, enhancing the heat dissipation capacity of the entire water jacket and making it sufficient to cope with the high temperature challenges brought by the high-temperature furnace.
