Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a cooling protective device. Background Technology

[0002] In industrial applications, ensuring that high-precision equipment such as industrial cameras, sensors, and other electronic devices operate at suitable temperatures is crucial. Excessively high operating temperatures not only affect equipment performance and stability but can also lead to damage or shortened lifespan. To address this challenge, various cooling solutions exist in existing technologies, among which air coolers are widely used due to their efficient and rapid cooling capabilities.

[0003] However, existing cooling devices typically have the following limitations:

[0004] Overall cooling rather than precise local cooling: Most existing technologies focus on cooling the entire instrument, rather than precisely controlling the temperature of specific components (such as the main body of an industrial camera).

[0005] Indirect temperature detection: Traditional temperature sensors monitor the air temperature surrounding the entire instrument to be cooled, rather than the temperature change of the instrument itself. This method cannot accurately reflect the true temperature state of the actual working components, resulting in untimely or inaccurate temperature regulation response. It may also cause large temperature fluctuations due to delays, affecting the normal operation of the instrument.

[0006] In addition, the cooling device has a relatively complex overall structure, making assembly and disassembly cumbersome. The structure of the entire cooling device is also relatively fixed, making it difficult to flexibly adjust to adapt to the needs of different equipment, thus limiting its use in diverse application scenarios. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cooling protection device. It not only solves the problems existing in the prior art, but also provides a new solution that is compact, fully functional and easy to maintain, and is particularly suitable for application scenarios that are sensitive to temperature and require efficient cooling.

[0008] The technical solution adopted by this application to solve its technical problem is: a cooling protection device, including a protective cover covering the instrument to be cooled, wherein the protective cover includes a plurality of covers arranged in sequence;

[0009] One of the covers is a heat-insulating cover, which covers the part of the instrument to be cooled to form a sealed heat-insulating cavity. The sealed heat-insulating cavity is connected to the cooling mechanism and the exhaust device, and the sealed heat-insulating cavity is equipped with a temperature sensing device.

[0010] The remaining covers are placed over the remaining parts of the instrument to be cooled, and adjacent covers are detachably connected.

[0011] The thermal insulation cover has at least one open end;

[0012] The open end of the insulation cover mates with the structure and seals of the instrument to be cooled, forming a sealed insulation cavity around the part to be cooled inside the insulation cover. This sealed insulation cavity prevents cold air from escaping during the insulation process, ensuring the insulation effect.

[0013] The sealing element includes one or more of a sealing gasket and a sealing ring.

[0014] The heat insulation cover is cylindrical;

[0015] At least one open end of an insulation cover has an inwardly recessed boss at the open end, the boss being detachably connected to an adjacent cover.

[0016] The inner wall of the boss is in contact with the outer wall of the instrument to be cooled, and the inner wall of the boss is provided with a groove, in which a sealing ring is provided.

[0017] The temperature sensor contacts the part to be cooled. The sensing end of the temperature sensor contacts the part to be cooled, directly sensing the temperature change of the part to be cooled, rather than the temperature change inside the sealed insulation cavity, ensuring the accuracy of temperature detection and more timely response when adjusting the temperature inside the sealed insulation cavity.

[0018] The cooling mechanism uses a cold air delivery component;

[0019] The cold air delivery assembly includes a cold air generator, and the air inlet of the cold air generator is connected to an air inlet valve;

[0020] The cold air outlet of the cold air generator is connected to the sealed insulation cavity.

[0021] The sealed and insulated cavity is connected to the cold air outlet of the cold air generator through a cold air inlet, and the sealed and insulated cavity is connected to the exhaust component through an exhaust port;

[0022] The cold air inlet and the exhaust outlet are respectively located on opposite sides of the insulation cover.

[0023] The exhaust component is a one-way valve, which automatically opens or closes based on the pressure difference between the sealed and insulated cavity and the outside.

[0024] The detachable connection includes one or more of the following: bolt connection, threaded connection, and snap-fit ​​connection.

[0025] Compared with existing technologies, this application has the following advantages: By placing the part to be cooled within a specially designed insulation cover, this application achieves precise localized cooling of critical components, rather than unnecessary cooling of the entire device. This not only improves energy efficiency but also ensures that critical components are always within their optimal operating temperature range.

[0026] The temperature sensor in this application directly contacts the surface of the part of the instrument to be cooled, monitoring its temperature changes in real time, rather than simply measuring the air temperature inside the sealed insulation cavity. This method provides more accurate temperature feedback, enabling the control system to respond more quickly to temperature fluctuations, ensuring optimal cooling, avoiding control lag, and guaranteeing equipment stability.

[0027] The protective cover consists of multiple detachable and interconnected enclosures, allowing for flexible configuration to meet the needs of different equipment, thus improving the system's adaptability and flexibility. The insulation enclosure, based on its own structure, the structure of the instrument to be cooled, and sealing components (such as sealing rings or gaskets), forms a relatively sealed cavity, ensuring that cold air within the sealed insulation cavity does not leak out, enhancing overall sealing performance. This modular design allows users to adjust the number and layout of cavities according to specific needs, improving adjustment flexibility.

[0028] Using a cold air generator as the cold air source, combined with a solenoid valve for automated control, not only reduces energy consumption but also simplifies the operation process, making the entire cooling process more economical and efficient. The insulation cover is made of insulation material, further enhancing the insulation effect, reducing energy loss, and helping to maintain a stable temperature environment, thus offering greater advantages in energy saving and insulation performance.

[0029] The entire device boasts a simple design, requiring only a few easy steps for installation and commissioning, significantly reducing operational complexity and facilitating routine maintenance and replacement, thereby enhancing the equipment's reliability and durability. Furthermore, the seals in this design prioritize ease of disassembly and cleaning, making it suitable for applications requiring frequent maintenance. Attached Figure Description

[0036] Example 1

[0037] Reference Figure 1 and Figure 2 A cooling protection device includes a protective cover 1 covering the instrument to be cooled, wherein the protective cover 1 includes a plurality of covers arranged sequentially;

[0038] One of the covers is a heat-insulating cover 101, which covers the part of the instrument to be cooled to form a sealed heat-insulating cavity 2. The sealed heat-insulating cavity 2 is connected to the cooling mechanism and the exhaust component 5, and the sealed heat-insulating cavity 2 is equipped with a temperature sensing component 4.

[0039] The remaining covers are placed over the remaining parts of the instrument to be cooled, and adjacent covers are detachably connected.

[0040] The detachable connection includes one or more of the following: bolt connection, threaded connection, and snap-fit ​​connection.

[0041] The heat insulation cover 101 is open at least one end;

[0042] The open end of the insulation cover 101 cooperates with the structure and sealing component 6 of the instrument to be cooled, so that the sealed insulation cavity 2 is formed inside the insulation cover 101 around the part to be cooled. The number of open ends of the insulation cover 101 can be set according to the relative position of the part to be cooled of the instrument.

[0043] The sealing element 6 includes one or more of a sealing gasket and a sealing ring. The specific selection depends on the adaptability of the instrument to be cooled. The sealing element 6, together with the part to be insulated, forms a relatively sealed space inside the insulation cover 101, preventing cold air from leaking out.

[0044] The heat insulation cover 101 is cylindrical;

[0045] At least one open end of the insulation cover 101 has an inwardly recessed boss 1011 at the open end, the boss 1011 being detachably connected to the adjacent cover. Specifically, the outer side of the boss 1011 is provided with an external thread, and the adjacent cover is provided with an internal thread that mates with it, thereby enabling the insulation cover 101 to be detachably and fixedly connected to the adjacent cover based on the threads.

[0046] The inner wall of the boss 1011 is in contact with the outer wall of the instrument to be cooled. The inner wall of the boss 1011 is provided with a groove 1012, and a sealing ring is provided in the groove 1012.

[0047] The temperature sensor 4 is in contact with the part to be cooled. The temperature sensor 4 can be a thermocouple or the like. The temperature sensor 4 directly senses the temperature change of the part to be cooled, rather than the temperature change inside the sealed insulation cavity 2, ensuring the accuracy of temperature detection and providing a more timely response when adjusting the temperature inside the sealed insulation cavity 2.

[0048] The cooling mechanism employs a cold air delivery assembly, which includes a cold air generator 7. Specifically, it can be a vortex cooler, a device capable of separating compressed gas into two streams of cold and hot air, achieving both cooling and heating effects. The cold air generator 7 includes a vortex chamber 704, with a cold air outlet 702 and a hot air outlet 703 at its two ends. An air inlet 701 is connected to the middle of the vortex chamber 704. The air inlet 701 of the cold air generator 7 is connected to an air compressor via an air inlet valve 3, which supplies compressed air to the vortex chamber 704. The compressed air entering the vortex chamber 704 generates a vortex effect due to the high-speed rotating airflow, thus separating the cold and hot air. The cold air enters the sealed insulation chamber 2 through the cold air outlet 702, while the hot air is directly discharged into the outside air through the hot air outlet 703. In this embodiment, the air inlet valve 3 can be a solenoid valve.

[0049] The sealed and heat-insulating cavity 2 is connected to the cold air outlet of the cold air generator 7 through the cold air inlet 1013, and the sealed and heat-insulating cavity 2 is connected to the exhaust component 5 through the exhaust port 1014;

[0050] The cold air inlet 1013 and the exhaust outlet 1014 are respectively located on opposite sides of the heat insulation cover 101.

[0051] The exhaust component 5 is a one-way valve, which opens or closes based on the pressure difference between the sealed insulation cavity 2 and the outside. The insulation cover 101 is made of insulation material to ensure the insulation effect within the sealed insulation cavity 2. During use, when the component to be cooled reaches the minimum value of the set temperature range, the cooling mechanism stops supplying cold air. Based on the insulation effect of the insulation cover 101, the heating rate of the component to be cooled is reduced, and the cold air supply component does not need to continuously supply cold air.

[0052] Insulation materials such as nylon have a low heat transfer coefficient and good insulation effect.

[0053] Figure 2 The direction of the middle arrow indicates the direction of airflow.

[0054] Working process: The operating temperature range of the part of the instrument to be cooled is preset (e.g., 45-55℃). In this application, the part of the instrument to be cooled is placed inside the insulation cover 101, and the remaining part of the cover is covered. At the connection between the insulation cover 101 and two adjacent covers, a sealed insulation cavity 2 is formed inside the insulation cover 101 based on the structure of the instrument and the sealing component 6. The temperature sensor 4 senses the temperature of the part of the instrument to be cooled in real time. If the temperature exceeds the maximum value of the set range, an electrical signal is sent to the air inlet valve 3, and compressed air enters the vortex cavity 704. The generated cold air enters the sealed insulation cavity 2 through the cold air inlet 1013 to cool the part to be cooled. At the same time, the exhaust component 5 is opened based on the air pressure difference between the sealed insulation cavity 2 and the outside to achieve the purpose of exhausting hot air. When the temperature inside the sealed insulation chamber 2 drops to the minimum value of the set range, the air inlet valve 3 closes, and the cold air generator 7 stops supplying cold air to the sealed insulation chamber 2. The air pressure inside the sealed insulation chamber 2 reaches equilibrium with the external air pressure, and the exhaust component 5 closes. The sealed insulation chamber 2 then enters the insulation stage until the temperature inside the sealed insulation chamber 2 rises back to the maximum value of the set range, at which point the cooling operation begins again.

[0055] Example 2

[0056] Reference Figure 2 Based on Embodiment 1, the instrument to be cooled in this embodiment includes a main body 8, a front end 9, and a rear end 10. The main body 8 is the part to be cooled. Thus, the protective cover 1 is provided with three covers corresponding to the three parts of the instrument to be cooled, specifically including a first cover 102, a heat preservation cover 101, and a third cover 103 arranged in sequence. Adjacent covers are detachably connected.

[0057] The heat insulation cover 101 is hollow and open at both ends. The two ends of the heat insulation cover 101 are detachably connected to one end of the first cover 102 and one end of the third cover 103, respectively. The inner wall shape of the heat insulation cover 101 is adapted to the shape of the part to be cooled (i.e., the main body 8) of the instrument to be cooled.

[0058] Furthermore, referring to Figure 2 In this application, a seal is formed on the upper part of the heat insulation cover 101 based on the instrument to be cooled and the sealing gasket; on the lower part of the heat insulation cover 101, a seal is formed between the inner wall of the boss 1011 and the instrument to be cooled by a sealing ring.

[0059] The entire protective cover 1 encloses the instrument to be cooled, providing protection. For connections between the instrument and the outside world, appropriate wiring terminals or ports can be installed on the protective cover 1.

[0060] By setting a separate sealed insulation chamber 2 for the cooling section, cold air is introduced into the sealed insulation chamber 2 for cooling. At the same time, the hot air after heat exchange is discharged through the exhaust pipe 5. When the preset temperature is reached, the supply of cold air can be stopped. The sealed insulation chamber 2 has a heat preservation effect and can maintain the low temperature effect for a long time.

[0061] Example 3

[0062] Based on Embodiment 2, the instrument to be cooled can specifically be a camera assembly, with the main body 8 corresponding to the camera body, the front end 9 corresponding to the camera lens, and the rear end 10 corresponding to the connecting wire. Thus, a heat insulation cover 101 covers the main body 8, a first cover 102 covers the front end 9, and a third cover 103 covers the rear end 10. The three covers are detachably connected, and a sealing element 6 is provided at the connection point based on the structure of the instrument to be cooled, so that the heat insulation cover 101 forms a relatively sealed cavity. For the camera-to-cool-down instrument, the end port of the first cover 102 corresponding to the lens can be sealed with glass (such as optical glass or polarizing film). The glass provides an additional layer of protection for the lens, preventing external contamination, without hindering image acquisition. For industrial camera applications, this achieves comprehensive protection without affecting the functionality of the equipment.

[0063] Example 4

[0064] Based on Example 1, the instrument to be cooled may only include the part to be cooled and other parts. In this case, the protective cover 1 can be provided with two covers corresponding to the above-mentioned parts. One cover is the heat preservation cover 101, which covers the part to be cooled, and the other cover covers the other parts of the instrument to be cooled.

[0065] The insulation cover 101 is detachably connected to another cover. In this case, the insulation cover 101 only needs to have one opening, and a boss 1011 is provided at the end of the opening. The boss 1011 is detachably connected to the other cover by threads.

[0066] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
