Description

Technical Field

[0001] This disclosure relates to the field of industrial camera technology, and more particularly to a cooling and heat insulation device. Background Technology

[0002] Industrial cameras are widely used in industries such as production inspection and scientific research due to their high resolution, high stability, and strong adaptability. When industrial cameras operate in high-temperature environments, such as when acquiring images inside hot chambers like blast furnaces or molten metal furnaces, they are highly susceptible to the effects of high temperatures, leading to unstable performance, degraded image quality, and shortened lifespan. To ensure stable operation of industrial cameras in high-temperature environments, cooling and heat dissipation measures are necessary.

[0003] Currently, heat dissipation is often achieved by adding heat sink fins to the camera housing or by using forced convection cooling. However, heat sink fins have poor heat dissipation efficiency and limited heat dissipation in high-temperature environments. While air cooling has a significant heat dissipation effect, the lifespan of the fan is limited, especially in high-temperature and dusty environments, where it generates a lot of noise, affecting the data acquisition effect of industrial cameras.

[0036] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0037] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0038] The overall structure of the cooling and heat insulation device in this embodiment is as follows: Figure 1 As shown, this is applicable to industrial camera 100. (As shown) Figure 2 and Figure 3 As shown, the cooling and heat insulation device includes an inner shell assembly 1 and an outer shell assembly 2. The inner shell assembly 1 has a hollow shell structure, and a vacuum chamber for housing an industrial camera 100 is formed inside. The industrial camera 100 is assembled in this vacuum chamber, which provides a good heat insulation environment for the industrial camera 100. The end of the inner shell assembly 1 has a transparent portion 10, such as... Figure 2 As shown, the camera 101 of the industrial camera 100 is aligned with the transparent portion 10 to capture images externally through the transparent portion 10. The structure of the housing assembly 2 is as follows. Figure 3As shown, the outer shell assembly 2 is also a hollow shell structure with a cooling channel 20 for coolant flow inside. The cooling channel 20 can be connected to an existing liquid cooling device to achieve liquid cooling effect. The outer shell assembly 2 is completely fitted over the inner shell assembly 1, with the transparent part 10 exposed outside the outer shell assembly 2. The peripheral wall of the outer shell assembly 2 is spaced a certain distance from the peripheral wall of the inner shell assembly 1 to form a heat insulation cavity layer, so that the outer shell assembly 2 and the inner shell assembly 1 will not have large-area direct contact, reducing heat transfer and effectively improving the heat insulation effect.

[0039] The overall structure of this cooling and heat insulation device is simple. It adopts a double-layer heat insulation structure. The vacuum chamber of the inner shell component 1 can provide a good vacuum heat insulation environment for the industrial camera 100. The outer shell component 2 is spaced apart from the inner shell component 1, and the interior of the outer shell component 2 is provided with a cooling channel 20. The outer shell component 2 itself has a liquid cooling function. Under high temperature conditions, the outer shell component 2 can effectively reduce its own temperature through liquid cooling to prevent the industrial camera 100 from being affected by the high temperature environment. In addition, since the outer shell component 2 and the inner shell component 1 are circumferentially spaced to form a heat insulation cavity layer, the heat insulation cavity layer can effectively prevent heat from being conducted to the inner shell component 1. The heat insulation effect is good and can effectively ensure that the industrial camera 100 is at a suitable working temperature and is not affected by the external high temperature conditions.

[0040] Furthermore, such as Figure 3 As shown, the outer casing assembly 2 specifically includes an outer casing body 21 and an outer casing cover 22. The outer casing body 21 has a receiving cavity 210 for accommodating the inner casing assembly 1. A cooling channel 20 is disposed within the outer casing body 21, specifically within the wall surface of the outer casing body 21. A heat insulation cavity layer is formed between the inner peripheral wall of the outer casing body 21 and the outer peripheral wall of the inner casing assembly 1. A window 211 is provided at the first end of the outer casing body 21. (Refer to the attached reference.) Figure 1 In this embodiment, the window 211 is a through-hole structure. The inner shell assembly 1 is fully assembled inside the accommodating cavity 210. One end of the inner shell assembly 1 with the transparent portion 10 extends out of the window 211, allowing the industrial camera 100 to take pictures. In other embodiments, a transparent structure can be added to the window 211, and the inner shell assembly 1 can be completely placed inside the outer shell body 21, which also enables the industrial camera 100 to take pictures. The design can be selected according to the actual situation. The outer shell cover 22 is connected to the second end of the outer shell body 21 and is used to cover the accommodating cavity 210. (Refer to reference...) Figure 1 The outer cover 22 has a wire hole 221 for the transmission bus 102 of the industrial camera 100 to pass through. The transmission bus 102 is electrically connected to the industrial camera 100 to transmit the real-time acquired signal data to the outside.

[0041] Furthermore, such as Figure 3As shown, the cooling channel 20 of this embodiment includes an inlet channel 201 and an outlet channel 202 that are interconnected. Along the radial direction of the outer shell body 21, the inlet channel 201 is disposed close to the inner wall of the outer shell body 21, and the outlet channel 202 is disposed close to the outer wall of the outer shell body 21. That is, the cooling channel 20 of this embodiment is approximately U-shaped. The inlet channel 201 is disposed as close as possible to the inner wall of the outer shell body 21, and the outlet channel 202 is disposed as close as possible to the outer wall of the outer shell body 21. Both the inlet channel 201 and the outlet channel 202 extend along the axial direction of the outer shell body 21. The inlet channel 201 and the outlet channel 202 are connected at the first end of the outer shell body 21 (that is, the end where the window 211 is provided). It is understood that the coolant flows in from the inlet channel 201 and flows out through the outlet channel 202. The coolant temperature in the inlet channel 201 is relatively low. Therefore, in this embodiment, the inlet channel 201 is preferably located close to the inner wall of the outer shell body 21 to minimize the temperature of the container cavity 210 and thus reduce the heat transfer to the inner shell assembly 1. When the coolant absorbs heat, its temperature rises and it is discharged through the outlet channel 202 to avoid the hot coolant circulating inward and to maximize the cooling effect on the inner shell assembly 1.

[0042] Furthermore, the housing assembly 2 also includes an inlet seal 23, an outlet seal 24, an inlet pipe 25, and an outlet pipe 26. For example... Figure 3 and Figure 4 As shown, the second end of the outer casing 21 (i.e. Figure 3 The top surface of the outer casing 21 shown has an inlet groove (not shown) and an outlet groove (not shown). The inlet groove is connected to the inlet channel 201, and the outlet groove is connected to the outlet channel 202. The inlet seal 23 is sealed to the opening of the inlet groove. The inlet pipe 25 passes through the inlet seal 23 and communicates with the inlet groove. The outlet seal 24 is sealed to the opening of the outlet groove, and the outlet pipe 26 passes through the outlet seal 24 and communicates with the outlet groove. Coolant enters the inlet groove through the inlet pipe 25, flows further into the inlet channel 201, absorbs heat, flows into the outlet groove through the outlet channel 202, and is finally discharged through the outlet pipe 26. The inlet pipe 25 and the outlet pipe 26 are connected to the coolant supply end and coolant recovery end of the liquid cooling device, respectively, to realize the supply of coolant.

[0043] Furthermore, such as Figure 3As shown, this embodiment has multiple sets of cooling channels 20, which are evenly spaced along the circumference of the outer shell 21. Both the inlet and outlet channels in this embodiment are annular. The inlet channel 201 is located near the inner wall of the outer shell 21, and the outlet channel 202 is located near the outer wall of the outer shell 21. Correspondingly, the inlet channel is also located in the inner ring of the end face of the outer shell 21, and the outlet channel is located in the outer ring of the end face of the outer shell 21. The inlet channels of the multiple cooling channels 20... 201 is connected to the inlet tank, and the outlet channels 202 of the multiple cooling channels 20 are connected to the outlet tank. The inlet seal 23 and the outlet seal 24 are also annular structures, and are respectively sealed to the opening of the inlet tank and the opening of the outlet tank. The coolant enters the inlet tank through the inlet pipe 25, and flows into each inlet channel 201 through the inlet tank. After absorbing heat, it flows into the outlet tank through each outlet channel 202, and finally is discharged through the outlet pipe 26 to realize the circulation of coolant in multiple cooling channels 20.

[0044] Optionally, such as Figure 3 As shown, the inlet channel 201 and the outlet channel 202 extend along the axial direction of the outer casing 21, and the first end of the outer casing 21 (i.e., Figure 3 The bottom of the outer shell body 21 shown is provided with a connecting groove 212. The connecting groove 212 extends radially along the outer shell body 21. In this embodiment, the connecting groove 212 is a strip-shaped groove. The liquid inlet channel 201 is connected to the liquid outlet channel 202 through the connecting groove 212 so that the cooling channel 20 is U-shaped. In addition, other methods can also be used to achieve the effect of U-shaped cooling channel 20, such as directly processing the cooling channel 20 into a U-shape during processing, including but not limited to the method shown in this embodiment.

[0045] Furthermore, the cooling and heat insulation device in this embodiment also includes a limiting component 3. For example... Figure 3 , Figure 5 and Figure 6 As shown, the limiting component 3 includes a limiting groove 31 and a limiting protrusion 32, with the limiting groove 31 extending axially along the outer shell component 2. In the inner shell component 1 and the outer shell component 2, one is provided with the limiting groove 31, and the other is correspondingly provided with a limiting protrusion 32 that slides in connection with the limiting groove 31, thereby achieving a limiting connection between the inner shell component 1 and the outer shell component 2. Specifically, as... Figure 2 As shown, in this embodiment, multiple limiting protrusions 32 are provided on the outside of the inner shell assembly 1. These limiting protrusions 32 are arranged in multiple groups. For example, in this embodiment, one group of limiting protrusions 32 includes six limiting protrusions 32, which are evenly spaced along the axial direction of the inner shell assembly 1. Correspondingly, as... Figure 3As shown, a limiting groove 31 is axially provided on the inner wall surface of the outer shell body 21, and the limiting protrusion 32 can be correspondingly inserted into the limiting groove 31 and is slidably connected to the limiting groove 31. More specifically, as Figure 6 shown, the limiting protrusion 32 of this embodiment is approximately in the shape of the Chinese character "丰", and the cross-sectional shape of the limiting groove 31 is adapted to the shape of the limiting protrusion 32 to prevent the limiting protrusion 32 from easily disengaging from the limiting groove 31. It can be understood that when assembling the inner shell assembly 1 into the outer shell assembly 2 in this embodiment, first disassemble the outer shell cover 22, align the limiting protrusion 32 on the outer periphery of the inner shell assembly 1 and insert it into the limiting groove 31, then push down the inner shell assembly 1, and finally assemble the outer shell cover 22 to achieve the assembly connection between the inner shell assembly 1 and the outer shell assembly 2.

[0046] Furthermore, as Figure 6 shown, the limiting component 3 further includes a heat insulation layer 33, and the heat insulation layer 33 is provided at the contact connection between the limiting protrusion 32 and the limiting groove 31. The heat insulation layer 33 is made of heat insulation material. In this embodiment, it is preferably covered on the outer surface of the limiting protrusion 32, and at least the contact surface between the limiting protrusion 32 and the limiting groove 31 should be covered to prevent the heat of the outer shell assembly 2 from being further transmitted to the inner shell assembly 1 through the limiting groove 31 and the limiting protrusion 32.

[0047] Furthermore, as Figure 2 shown, the inner shell assembly 1 of this embodiment includes an inner shell body 11, a transparent member 12 and an inner shell cover 13. The inner shell body 11 has a hollow structure with both ends penetrating. The transparent member 12 is hermetically connected to one axial end of the inner shell body 11 to serve as the transparent part 10. The transparent member 12 is made of commonly used heat insulation transparent material in the field, and this embodiment does not specifically limit this material. The inner shell cover 13 is hermetically connected to the other axial end of the inner shell body 11. The inner wall of the inner shell body 11 is conformally arranged with the outer wall of the industrial camera 100 to achieve the limitation of the industrial camera 100. Exemplarily, the industrial camera 100 of this embodiment is composed of a cylindrical camera head 101 structure and a square fuselage main body. The inner shell body 11 is conformally arranged with the industrial camera 100, and the inner shell body 11 also includes a cylindrical structure for supporting and accommodating the camera head 101 and a square structure for supporting and accommodating the fuselage main body. The inner shell body 11, the transparent member 12 and the inner shell cover 13 enclose a vacuum chamber. One axial end of the inner shell body 11 extends out of the window 211. A data adapter 131 electrically connected to the industrial camera 100 is provided on the inner shell cover 13. As Figure 7 shown, with reference to the attached Figure 2The data adapter 131 is a metal conductive post that is welded to the middle of the inner shell cover 13 and passes through the inner shell cover 13. One end of the data adapter 131 extends into the vacuum chamber and is electrically connected to the industrial camera 100, and the other end is electrically connected to the transmission bus 102, so that the data information collected by the industrial camera 100 is transmitted to the external device through the data adapter 131 and the transmission bus 102. The data adapter 131 is pre-welded to the inner shell cover 13, which reduces the problem of poor sealing caused by the need to open a hole when the data line passes through the inner shell cover 13.

[0048] For example, the vacuum conditions of the vacuum chamber in this embodiment can be achieved by various means. For instance, after the industrial camera 100 is assembled into the inner shell body 11, a through hole is provided in the inner shell body 11 or the inner shell cover 13. A vacuum device is connected to the through hole to evacuate the space enclosed by the inner shell body 11, the transparent part 12 and the inner shell cover 13 to form a vacuum chamber. Finally, the through hole is sealed. Alternatively, the inner shell assembly 1 can be assembled in a vacuum environment. This embodiment does not elaborate on the specific methods of achieving the vacuum conditions. For details, please refer to the prior art.

[0049] Optionally, in this embodiment, one end of the transmission bus 102 that is electrically connected to the data adapter 131 is provided with a threaded connector, and the data adapter 131 is provided with an external thread on its outer periphery. The data adapter 131 is screwed into the threaded connector of the transmission bus 102 to realize the connection between the transmission bus 102 and the data adapter 131.

[0050] Furthermore, to further improve the cooling effect of the cooling and insulation device, this embodiment adopts a dual cooling method of liquid cooling and air cooling. For example... Figure 3 As shown, the outer casing 21 has a cooling air duct (not shown in the figure) for cooling air to circulate. The cooling air duct also extends along the axial direction of the outer casing 21, and a vent 27 for cooling air to flow out is formed on the end face of the second end of the outer casing 21. The cooling air duct is connected to an existing air-cooling device, which provides a continuous supply of cooling air to the cooling air duct to further reduce the temperature of the outer casing 21. After absorbing heat in the cooling air duct, the cooling air is discharged through the vent 27. The cooling air can also clean the shooting area by blowing away dust. It is understood that since the industrial camera 100 of this embodiment is often used in high-temperature environments such as blast furnaces or furnaces, there is a large amount of dust inside the blast furnace or furnace. The cooling air after absorbing heat can be discharged through the vent 27 to clean the shooting area by blowing away dust, which helps to improve the shooting effect.

[0051] Preferably, in this embodiment, the cooling air duct is located between the liquid outlet channel 202 and the outer wall of the outer casing 21. That is, compared to the liquid outlet channel 202, the cooling air duct is located on the outermost side of the outer casing 21. The outer casing consists of the liquid inlet channel 201, the liquid outlet channel 202, and the cooling air duct, arranged sequentially from the inner wall to the outer wall. For example, as shown... Figure 3 and Figure 4 As shown, the housing assembly 2 also includes an air inlet seal 28 and an air inlet pipe 29, and the second end of the housing body 21 (i.e., Figure 3 An air inlet slot (not shown in the figure) is provided on the end face of the top of the outer shell body 21. Multiple cooling air channels are provided, and the multiple cooling air channels are evenly spaced along the circumference of the outer shell body 21. The air inlet slot is connected to the multiple cooling air channels. The air inlet seal 28 is sealed to the slot opening of the air inlet slot. The air inlet pipe 29 passes through the air inlet seal 28 and is connected to the air inlet slot. The air inlet pipe 29 is connected to the air cooling device. Cooling air enters the air inlet slot through the air inlet pipe 29, flows further into the cooling air channel through the air inlet slot, and is then discharged from the corresponding air hole 27.

[0052] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
