Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0034] Reference Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the structure of the first embodiment of the explosion-relief device provided in this application. Figure 2 This is a cross-sectional view of the first embodiment of the rupture pressure relief device provided in this application. This embodiment discloses a rupture pressure relief device 1, applied to a radiator (the radiator can be a thermosiphon radiator). The radiator includes a pressure vessel 3, which has a pressure chamber 31. The rupture pressure relief device 1 includes a rupture component 2, which is connected to the pressure vessel 3. The rupture component 2 has a cavity 21, which communicates with the pressure chamber 31. The inner wall of the cavity 21 has a rupture zone 210, the wall thickness of which is less than the wall thickness of the pressure chamber 31. When the pressure in the pressure chamber 31 reaches the rupture pressure of the rupture zone 210, the rupture zone 210 ruptures or falls off and cannot be repeatedly closed. It is a one-time pressure relief device, with a simpler structure and lower cost compared to other pressure relief devices, thus reducing costs.

[0035] In this embodiment, the blasting component 2 is used to connect to the pressure vessel 3 by welding, which eliminates the need for drilling and saves processing time. The welded connection has good sealing performance, which reduces the leakage of fluid in the pressure chamber 31 and cavity 21 from the connection between the blasting component 2 and the pressure vessel 3, thereby ensuring the normal operation of the blasting pressure relief device 1 and the radiator.

[0036] In the embodiment, the blasting assembly 2 is made of metal material, which is convenient for welding, thereby facilitating the connection of the blasting assembly 2 and the pressure container 3. Specifically, the blasting assembly 2 is made of aluminum alloy material, which can form a dense oxide film on the surface when in contact with air to prevent corrosion, thereby ensuring the corrosion resistance of the blasting assembly 2. In addition, the aluminum alloy has high strength and good processing performance, and is easy to bend, which is convenient for application in the bending part of the pipeline, thereby improving the applicability of the blasting assembly 2. It can be understood that in other embodiments, the blasting assembly 2 can also be made of other metal materials, such as stainless steel, copper, etc.

[0037] In the embodiment, the blasting pressure of the blasting area 210 is less than the system pressure of the radiator. The system pressure of the radiator is the pressure-bearing capacity of any place of the radiator. For example, when the blasting area 210 is set to be blasted at a pressure of 8 MPa, the pressure-bearing capacity of any place of the radiator needs to be greater than 8 MPa to ensure that the blasting area 210 is blasted first, thereby protecting the radiator from overpressure damage and effectively ensuring the safety of the radiator.

[0038] The blasting pressure relief device 1 of the embodiment is applied to a radiator. The radiator includes a pressure container 3 provided with a pressure cavity 31. The blasting assembly 2 is provided with a cavity 21 in communication with the pressure cavity 31. The inner wall of the cavity 21 is provided with a blasting area 210. The wall thickness of the blasting area 210 is less than that of the pressure cavity 31, so that the blasting area 210 is the thinnest part. When the pressure in the pressure cavity 31 reaches the blasting pressure of the blasting area 210, the blasting area 210 breaks or falls off, thereby rapidly reducing the pressure in the pressure container 3, reducing the damage of the radiator caused by overpressure, and effectively ensuring the safety of the radiator. In addition, the wall thickness of the blasting area 210 can be set according to the required blasting pressure, and the installation position of the blasting pressure relief device 1 can be adjusted according to the required blasting position, thereby realizing accurate control of the blasting pressure and blasting at the ideal position, reducing unnecessary damage, and reducing costs.

[0039] Continuing to refer to Figure 1 and Figure 2 , the pressure container 3 includes a pipeline, and the pipeline forms the pressure cavity 31 inside. The blasting assembly 2 includes a blasting pipe 22, and the blasting pipe 22 forms the cavity 21 inside. The inner wall of the blasting pipe 22 is the blasting area 210, and the wall thickness of the blasting pipe 22 is less than that of the pipeline. The pipeline includes a first connecting pipe 32 and a second connecting pipe 33. The two ends of the blasting pipe 22 are respectively welded and connected with the first connecting pipe 32 and the second connecting pipe 33, and the blasting pipe 22 is coaxially arranged with the first connecting pipe 32 and the second connecting pipe 33, so that the blasting pipe 22 is a place that the fluid in the pressure cavity 31 must pass through, thereby ensuring the normal work of the blasting pressure relief device 1.

[0040] In this embodiment, the inner diameter of the rupture tube 22 is smaller than the inner diameter of the pipe, meaning the outer surface of the rupture tube 22 is connected to the inner surface of the pipe. This allows one end of the rupture tube 22 to be stacked with the first connecting pipe 32 along the radial direction, and the other end to be stacked with the second connecting pipe 33. This increases the connection area between the rupture tube 22 and the first and second connecting pipes 32 and 33, thereby enhancing the connection strength between the rupture tube 22 and the first and second connecting pipes 32 and improving the bursting speed. Regarding the sealing of the connection between the rupture tube 22 and the first connecting tube 32 and the second connecting tube 33, it is understood that in other embodiments, the inner diameter of the rupture tube 22 may be larger than the inner diameter of the pipe, that is, the inner surface of the rupture tube 22 may be connected to the outer surface of the pipe; or, the inner diameter of the rupture tube 22 may be equal to the inner diameter of the pipe, that is, one end of the rupture tube 22 may be welded to the end of the first connecting tube 32, and the other end of the rupture tube 22 may be welded to the end of the second connecting tube 33, so as to reduce the use of rupture tube 22 material and save costs.

[0041] In this embodiment, the rupture tube 22 is made of AL3003-h state, with an outer diameter of 16 mm, a wall thickness of 0.55 mm, and a rupture pressurization rate of 10 MPa / min. When pressurized to about 9 MPa, it will rupture at a fixed rupture point. In specific applications, the material and structure of the rupture tube 22 can be set as needed.

[0042] In one embodiment, the bursting pipe 22 is configured to be integrally formed with the first connecting pipe 32 and the second connecting pipe 33, thereby enabling the bursting pipe 22 to be directly processed on the outside of the pipe, which is convenient for processing and reduces the steps of connecting the bursting pipe 22 with the first connecting pipe 32 and the second connecting pipe 33, thus improving processing efficiency.

[0043] Reference Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the second embodiment of the explosion-relief device provided in this application. Figure 4This is a cross-sectional view of a second embodiment of the rupture pressure relief device provided in this application. The rupture assembly 2 includes a mounting block 23 and a rupture disc 24. The mounting block 23 is used to connect to the pressure vessel 3, and the mounting block 23 has a groove 230 and a through hole 231 that are interconnected. The groove 230 has a cavity 21. The rupture disc 24 is sealed in the through hole 231, and the inner wall of the rupture disc 24 is a rupture zone 210. The thickness of the rupture disc 24 is less than the wall thickness of the groove 230. Since the wall thickness of the rupture zone 210 is less than the wall thickness of the pressure cavity 31, the rupture disc 24 is the weakest point, thereby allowing the rupture disc 24 to rupture first, ensuring the practicality of the rupture pressure relief device 1. The pressure vessel 3 may also include a cold plate, with the mounting block 23 welded to the cold plate and the groove 230 connected to the flow channel of the cold plate. When the flow channel is blocked, the pressure inside the flow channel gradually increases. When the pressure reaches the burst pressure of the rupture disc 24, the rupture disc 24 ruptures or falls off, thereby reducing the pressure inside the flow channel and ensuring the safety of the radiator.

[0044] In this embodiment, the rupture disc 24 is located at the end of the through hole 231 near the groove 230. The rupture disc 24 and the mounting block 23 are integrally formed. During processing, a groove can be directly machined on the mounting block 23 along the direction near the groove 230. The bottom wall of the groove is the rupture disc 24, and the bottom wall of the groove is the inner wall of the groove 230. That is, the rupture disc 24 can be formed by opening a groove, which is convenient for processing. It can be understood that in other embodiments, the rupture disc 24 can also be separately set from the mounting block 23. After the thickness of the rupture disc 24 is processed, the rupture disc 24 can be connected to the inner wall of the through hole 231 by welding.

[0045] In this embodiment, the rupture disc 24 is a flat rupture disc. Flat rupture discs have a simple structure, low cost, and good sealing performance, which can reduce the risk of leakage while ensuring safety. It is understood that in other embodiments, the rupture disc 24 can also be an inverted arch rupture disc, with the convex surface of the inverted arch rupture disc facing the cavity 21. When the pressure exceeds the set value, the inverted arch rupture disc will flip and break or fall off due to compression instability. It belongs to the compression type rupture disc. The inverted arch rupture disc has excellent fatigue resistance and can work stably under high pressure. It is not easy to burst prematurely, thus ensuring the stability of the rupture disc 24. Alternatively, the rupture disc 24 can also be a positive arch rupture disc, with the concave surface of the positive arch rupture disc facing the cavity 21. When the pressure exceeds the set value, the positive arch rupture disc will break due to tension. It belongs to the tension type rupture disc.

[0046] In this embodiment, the rupture disc 24 is circular. When a circular rupture disc is subjected to pressure, the pressure can be evenly distributed, thereby improving its compressive strength and ensuring the stability of the rupture disc 24. In specific applications, the shape of the rupture disc 24 can be set as needed and is not limited here.

[0047] In this embodiment, the cross-section of the mounting block 23 is approximately circular so that the pressure can be evenly distributed when subjected to pressure, thereby improving its compressive strength and ensuring the stability of the mounting block 23. The mounting block 23 is provided with a plane, and the plane is provided with a through hole 231. The plane facilitates the processing of the through hole 231 and improves the processing efficiency.

[0048] Based on the above embodiments, this application also provides a radiator including the explosion-relief device described in any of the above embodiments. Since the radiator provided by this application includes the explosion-relief device, it also has the same technical effects as the explosion-relief device, and will not be described again here.

[0049] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
