Description

Technical Field

[0001] The present application belongs to the technical field of radiator manufacturing, and in particular relates to a radiator, electrical equipment and a pressure relief device. Background Art

[0002] When the phase change radiator is working normally, it has high requirements for temperature and pressure. In order to ensure its reliable application, the radiator processing technology is generally required to be high, and there is room for improvement. Utility Model Content

[0003] This application aims to at least address the technical issue of secondary damage in related technologies. To this end, this application proposes a radiator, electrical equipment, and pressure relief device that can automatically release pressure within the radiator cavity at a specific location, thereby preventing secondary damage to the entire device caused by the radiator exploding under extreme operating conditions.

[0004] In a first aspect, the present application provides a heat sink, comprising:

[0005] condenser;

[0006] an evaporator, connected to the condenser;

[0007] Wherein, at least one of the condenser, the evaporator, and the medium channel between the condenser and the evaporator is provided with a pressure relief structure.

[0008] According to the radiator provided in the embodiment of the present application, by designing a weak structure as the pressure relief structure, the pressure can be released at a fixed point under specific conditions, and the pressure relief process can be made more controllable, so as to avoid secondary damage to the entire machine caused by the explosion of the radiator under extreme working conditions, and at the same time reduce the potential impact on the surrounding environment or equipment caused by pressure release.

[0009] According to one embodiment of the present application, the evaporator includes:

[0010] A flow channel plate, wherein a first surface of the flow channel plate forms a flow channel opening communicating with the air pipe and the liquid pipe;

[0011] A cover plate is mounted on the first surface of the flow channel plate, and the pressure relief structure is provided on the cover plate.

[0012] The flow channel plate can guide the fluid or material to flow in a specific path and control its flow speed and direction. At the flow channel outlet, the flow rate of the fluid is faster and the pressure reaches the maximum accordingly. The pressure relief structure is arranged on the cover plate and releases the pressure under specific conditions, which can prevent secondary damage to the entire machine caused by explosion of the equipment under extreme working conditions.

[0013] According to one embodiment of the present application, the cover plate is provided with a pressure relief port facing the flow channel port, and the pressure relief structure includes:

[0014] A protective sheet is fitted with the cover plate and closes the pressure relief port, and the connection strength of at least one connection position between the protective sheet and the cover plate is less than the strength of the cover plate itself.

[0015] The protective sheet fits tightly onto the cover plate and can close the pressure relief port during normal operation to prevent leakage of liquid or gas. In certain circumstances, it can break before the cover plate, thereby releasing pressure.

[0016] According to one embodiment of the present application, the protective sheet is detachably connected to the cover plate.

[0017] Fixing with threaded connectors can effectively control the pressure at the pressure relief structure. Threaded connectors not only ensure the stability and sealing of the structure, but also can accurately control the pressure by adjusting the degree of tightening.

[0018] According to one embodiment of the present application, the protective sheet is sealed to the cover plate.

[0019] The sealant can fill the tiny gaps or unevenness that may exist between the protective sheet and the cover plate, ensuring a tight bond between the two and effectively preventing the intrusion of external factors such as water, gas and dust, thereby protecting the electrical, mechanical or other key components inside the protective sheet and the cover plate from damage.

[0021] The structural strength of the target area is lower than that of other parts of the cover plate. When the pressure reaches a critical value, the target area is more likely to rupture. When the target area ruptures under high pressure, the pressure at the flow channel outlet can be quickly and effectively released through the target area, thereby realizing the pressure relief function, reducing the potential impact of pressure release on the surrounding environment or equipment, and improving the safety of the entire system.

[0022] According to one embodiment of the present application, the radiator further includes:

[0023] an air pipe, through which the outlet of the evaporator is connected to the inlet of the condenser;

[0024] a liquid pipe, through which the inlet of the evaporator and the outlet of the condenser are connected;

[0025] The pressure relief structure includes a pressure relief section provided on at least one of the collecting pipe of the condenser, the gas pipe and the liquid pipe, and the strength of the pressure relief section is lower than the strength of other areas of the radiator.

[0026] The pressure relief structure plays an important role in safety protection in the condenser, the evaporator, the gas pipe, the liquid pipe and other components. Reasonable design and implementation can ensure that the system can safely release pressure under abnormal circumstances and reduce the impact on the overall system.

[0027] According to one embodiment of the present application, the wall thickness of the pressure relief section is smaller than the wall thickness of other regions of at least one of the gas pipe, the liquid pipe, and the header of the condenser;

[0032] The material strength of one of the gas pipe, the liquid pipe and the condenser collecting pipe is lower than that of the other pipes to form the pressure relief section;

[0033] and / or,

[0034] The inner diameter of one of the gas pipe, the liquid pipe and the collecting pipe of the condenser is larger than that of the other pipes to form the pressure relief section.

[0035] The refrigerant is transported through the gas pipe, the liquid pipe and the collecting pipe of the condenser, forming a refrigerant circulation loop as a whole, which can effectively collect and transmit fluids and improve the operating efficiency of the system. The pressure relief section is set in at least one of the gas pipe, the liquid pipe and the collecting pipe of the condenser, which can guide the pressure to be released at a specific position, thereby realizing control of the pressure relief process, protecting the safety and integrity of the system, and not causing harm to personnel or equipment when releasing the pressure.

Through efficient heat transfer, the evaporator can keep the power device at a lower operating temperature, thereby improving its operating efficiency.

[0044] The power device generates a large amount of heat during operation. As the heat is transferred and the radiator operates, pressure and temperature changes occur inside the second chamber. When the pressure reaches a certain level, the pressure relief structure automatically opens, allowing gas or liquid to be discharged from the second chamber, thereby maintaining the pressure balance within the system. Through the heat transfer between the power device and the radiator and the effective heat dissipation of the radiator, efficient heat management of the entire system can be achieved, ensuring that the power device can operate at an appropriate temperature, thereby improving its operating stability and reliability.

[0080] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0081] This application aims to at least solve the technical problem of secondary damage in the related art. To this end, this application proposes a radiator, electrical equipment and pressure relief device to prevent secondary damage to the entire device caused by the explosion of the phase change radiator under extreme working conditions.

[0082] Reference below Figures 1-9 A heat sink 10 according to an embodiment of the present application is described.

[0083] like Figure 1 and Figure 3 As shown, the radiator 10 includes a condenser 110 , an evaporator 120 , an air pipe 130 and a liquid pipe 140 .

[0084] The evaporator 120 is connected to the condenser 110 through the gas pipe 130 and the liquid pipe 140 . The outlet of the evaporator 120 is connected to the inlet of the condenser 110 through the gas pipe 130 , and the inlet of the evaporator 120 is connected to the outlet of the condenser 110 through the liquid pipe 140 .

[0085] The gas pipe 130 is connected to the outlet of the evaporator 120 and the inlet of the condenser 110 respectively. The refrigerant absorbs heat in the evaporator 120 and evaporates into gas, and then flows to the condenser 110 through the gas pipe 130 to release heat and condense into liquid. The liquid pipe 140 is connected to the inlet of the evaporator 120 and the outlet of the condenser 110 respectively. The refrigerant releases heat in the condenser 110 and condenses into liquid, and then flows to the evaporator 120 through the liquid pipe 140 to absorb heat and evaporate into gas.

[0086] The air pipe 130 can be made of flexible or rigid materials, such as metal, plastic or rubber, which can withstand a certain pressure and have a certain heat resistance. At the same time, a suitable connection method is designed, such as flange connection, threaded connection or brazing and other integrated welding methods, and sealing materials or gaskets are used at the connection to prevent gas leakage and ensure smooth gas transmission.

[0087] The liquid pipe 140 can be made of corrosion-resistant, high-pressure-resistant, high-temperature-resistant materials, such as copper, stainless steel or specific plastic materials. The connection between the liquid pipe 140 and the inlet of the evaporator 120 and the outlet of the condenser 110 can be connected by welding, threaded connection or flange connection. These connection methods can ensure good sealing and sufficient strength to prevent liquid leakage. In some cases, the liquid pipe 140 also needs to have a certain degree of flexibility to adapt to vibration and displacement during system installation and operation.

[0088] In this embodiment, the gas pipe 130 is connected to the outlet of the evaporator 120 and the inlet of the condenser 110 respectively. The refrigerant absorbs heat in the evaporator 120 and evaporates into gas, then flows through the gas pipe 130 to the condenser 110 to release heat and condense into liquid, and finally returns to the evaporator 120 through the liquid pipe 140, completing a complete refrigeration cycle. This cycle is repeated continuously to maintain the normal operation of the refrigeration system.

[0089] The gas-liquid conversion process is often accompanied by a significant increase in working pressure, so there is an explosion risk that cannot be ignored. The pressure relief structure 150 can release the pressure in time, thereby avoiding secondary damage to the entire machine caused by the explosion of the radiator 10 under extreme working conditions.

[0090] At least one of the condenser 110 , the evaporator 120 , the gas pipe 130 and the liquid pipe 140 is provided with a pressure relief structure 150 .

[0091] During actual operation, when the internal pressure exceeds a specific pressure threshold, the pressure relief structure 150 will automatically release the pressure. In order to release the pressure in time and prevent the pressure from continuing to rise, the pressure relief structure 150 should have a fast response characteristic and be able to start and release the pressure in a short time. At the same time, the pressure relief structure 150 has good sealing properties, which can prevent liquid or gas leakage and ensure that no harm is caused to personnel or equipment when the pressure is released.

[0092] In the related art, the protective performance of a radiator 10 with a similar structure will gradually decline after long-term use. This decline is often difficult to detect because the internal structure of the radiator 10 is complex and explosions may occur as the working conditions fluctuate. After long-term use, it is impossible to determine which part will first become disrepaired, making the location of the explosion point uncertain, increasing the difficulty and danger of accident handling.

[0093] In the technical solution of the present application, by designing a weak structure as the pressure relief structure 150, pressure can be released at a fixed point under specific conditions. For example, a weak structure is designed on the back of the evaporator 120 and the condenser 110 area. When the pressure reaches its bearing limit, the weak structure will rupture and release the pressure. At the same time, to ensure the effectiveness of the pressure relief structure 150, regular inspection and maintenance are required, and damaged or aged parts must be replaced in a timely manner.

[0094] It can be understood that the pressure relief structure 150 plays an important safety protection role in components such as the condenser 110, the evaporator 120, the gas pipe 130 and the liquid pipe 140. Reasonable design and implementation can ensure that the system can safely release pressure under abnormal circumstances and reduce the impact on the overall system.

[0095] In some embodiments, as Figure 3 and Figure 4 As shown, the evaporator 120 includes: a flow channel plate 121 and a cover plate 122 , wherein the first surface of the flow channel plate 121 forms a flow channel opening 123 , the cover plate 122 is installed on the first surface of the flow channel plate 121 , and the pressure relief structure 150 is provided on the cover plate 122 .

[0096] The main function of the flow channel plate 121 is to guide the fluid or material to flow in a specific path and control its flow speed and direction, which can reduce the energy loss and resistance of the fluid during the flow process and reduce the energy consumption of the equipment. The flow channel plate 121 can adopt a special design, such as a corrugated plate shape, so that the fluid generates high-intensity turbulence in the flow channel, which helps the fluid to flow evenly on the entire plate without heat exchange dead zones, thereby obtaining a good evaporation effect.

[0097] It can be understood that the first surface of the flow channel plate 121, that is, the surface in contact with the gas pipe 130 and the liquid pipe 140, is designed with specific flow channel openings 123. These flow channel openings 123 can allow the gaseous refrigerant transmitted in the gas pipe 130 and the liquid refrigerant transmitted in the liquid pipe 140 to smoothly enter the interior of the flow channel plate 121. Through the internal structure design of the flow channel plate 121, these refrigerants can be evenly distributed in the flow channel plate 121, thereby ensuring the efficient operation of the entire heat dissipation system.

[0098] The cover plate 122 may be provided with a pressure relief structure 150 . The pressure relief structure 150 may have various structural forms, including but not limited to:

[0099] In some embodiments, a protective sheet 151 type pressure relief structure 150 may be provided, such as Figure 5 and Figure 6 As shown, the cover plate 122 is provided with a pressure relief port 124 facing the flow channel port 123, and the pressure relief structure 150 includes: a protective sheet 151, the protective sheet 151 is fitted with the cover plate 122 and closes the pressure relief port 124, and the connection strength of at least one connection position between the protective sheet 151 and the cover plate 122 is less than the strength of the cover plate 122 itself.

[0100] In this embodiment, the protective sheet 151 can be made of a material with a certain degree of corrosion resistance, such as metal or a specific synthetic material, and fits tightly on the cover plate 122 to ensure that the pressure relief port 124 can be effectively closed during normal operation to prevent liquid or gas leakage. It is easy to open in specific circumstances to release pressure, and adopts a suitable connection method, such as spot welding, gluing or mechanical connection, to achieve the connection between the protective sheet 151 and the cover plate 122. At the same time, by adjusting the number, distribution and connection method of the connection points, the connection strength is controlled to ensure that it can be smoothly disconnected when needed.

[0101] During actual operation, when the fluid flows in the flow channel, its state presents vigorous turbulence. The flow channel opening 123 distributed on the first surface of the flow channel plate 121 and connected to the air pipe 130 and the liquid pipe 140 is the key channel for the fluid to enter and flow out of the flow channel, which not only ensures the smooth flow of the fluid, but also avoids excessive resistance of the fluid at the flow channel opening 123.

[0102] It can be understood that a pressure relief port 124 facing the flow channel port 123 can be provided on the cover plate 122, and the connection strength of at least one connection position between the protective sheet 151 and the cover plate 122 is less than the strength of the cover plate 122 itself. In this way, when the pressure exceeds a certain threshold, the protective sheet 151 can break before the cover plate 122, thereby realizing the pressure relief function. Compared with the rupture of the entire cover plate 122, the rupture of the protective sheet 151 is more controllable and has less impact on the overall system.

[0103] In some embodiments, as Figure 5 and Figure 6 As shown, the protective sheet 151 is detachably connected to the cover plate 122 , for example, the protective sheet 151 can be connected to the cover plate 122 via a threaded connection 152 .

[0104] In the technical solution of the present application, an area can be reserved on the integrally brazed backplate cover 122 and fixed with a detachable fixing method such as a threaded connector 152. The pressure of the structure here can be controlled by controlling the specifications and torque of the threaded connector 152, for example, by controlling the set value of the pressure here through multiple tests.

[0105] In actual working process, the threaded connection 152 is tightened by rotation. The selection of materials is usually based on factors such as the required strength, corrosion resistance, wear resistance, etc. Common materials include stainless steel, carbon steel, alloy steel, etc.

[0106] During installation, the threaded connector 152 is precisely controlled by using tools such as a torque wrench to ensure that a specific torque target value is reached, thereby ensuring the fastening force and stability of the connector and avoiding overtightening or overloosening. At the same time, in order to improve the corrosion resistance and wear resistance of the threaded connector 152, surface treatment such as galvanizing, spraying anti-rust paint, etc. can be performed.

[0107] It is understandable that the pressure at the pressure relief structure 150 can be effectively controlled by fixing with the threaded connector 152 . The threaded connector 152 not only ensures the stability and sealing of the structure, but also can accurately control the pressure by adjusting the degree of tightening.

[0108] In some embodiments, as Figure 5 and Figure 6 As shown, the protective sheet 151 is sealed to the cover plate 122 , and other sealing methods such as sealant 153 or sealing strips can be used. The sealant 153 is taken as an example below.

[0109] In the technical solution of the present application, in order to prevent risks at the threaded connector 152, sealing can be performed by adding rubber strips or applying glue, so that the installation area serves as a micro-leakage point under extreme working conditions. When selecting the threaded connector 152 for fixing, the specifications of the threaded connector 152 may be inconsistent or the threaded connector 152 may have a reinforced or weakened structure in some place to further confirm the location of the micro-leakage point.

[0110] It is understandable that there may be tiny gaps or unevenness between the protective sheet 151 and the cover plate 122, and the sealant 153 can fill these gaps to ensure a tight bond between the two. This tight bond can effectively prevent the intrusion of external factors such as water, gas, and dust, thereby protecting the electrical, mechanical or other key components inside the protective sheet 151 and the cover plate 122 from damage.

[0111] At the same time, the sealant 153 has good adhesion and can firmly bond the protective sheet 151 and the cover plate 122 together. This adhesion not only ensures the close connection and stability between the protective sheet 151 and the cover plate 122, but also prevents cracks or leakage caused by vibration, impact or other external forces, thereby reducing the occurrence of potential risks such as electrical failures and mechanical failures, and improving overall safety performance.

[0112] In other embodiments, the target area 154 type pressure relief structure 150, such as Figure 7 and Figure 8 As shown, the pressure relief structure 150 may include a target area 154 of the cover plate 122 . The strength of the target area 154 is lower than that of other areas of the cover plate 122 , and the target area 154 faces the flow channel opening 123 .

[0113] In this embodiment, the thickness of the target area 154 of the cover plate 122 can be made thinner so that it serves as a micro-leakage point under extreme working conditions. The connection structure between the target area 154 of the cover plate 122 and the flow channel plate 121 can also be designed to be weaker during brazing. At the same time, in order to identify micro-leaks in advance, a pressure sensor or a temperature sensor can be installed in the target area 154, and the pressure value of the pressure sensor can be set to be higher than the normal working value. In this way, whether the condenser 110 of the radiator 10 has a fault such as blockage can be identified in advance, so that regular maintenance can be performed.

[0114] During actual operation, when the fluid flows in the flow channel, its state presents vigorous turbulence. The flow channel opening 123 distributed on the first surface of the flow channel plate 121 and connected to the air pipe 130 and the liquid pipe 140 is the key channel for the fluid to enter and flow out of the flow channel, which not only ensures the smooth flow of the fluid, but also avoids excessive resistance of the fluid at the flow channel opening 123.

[0115] When the system is operating normally, the internal pressure gradually increases. The other parts of the cover 122 are relatively strong and the pressure distribution is relatively uniform. The target area 154 is a weak link designed on the cover 122, and its structural strength is lower than that of other parts of the cover 122. When the internal pressure of the system reaches a critical value, the target area 154 is more likely to rupture, thereby releasing the pressure. Compared with the rupture of the entire cover 122, the rupture of the target area 154 is more controllable and has less impact on the overall system.

[0116] It can be understood that the structural strength of the target area 154 is lower than that of other parts of the cover plate 122, and it is more likely to rupture when the pressure reaches a critical value. When the target area 154 ruptures under high pressure, the pressure at the flow channel opening 123 can be quickly and effectively released through the target area 154, thereby realizing the pressure relief function, which can reduce the potential impact of pressure release on the surrounding environment or equipment and improve the safety of the entire system.

[0117] In some embodiments, as Figure 9 As shown, the pressure relief structure 150 includes a pressure relief section 155 provided in at least one of the manifold 111 , the gas pipe 130 and the liquid pipe 140 of the condenser 110 . The strength of the pressure relief section 155 is lower than that of other areas of the radiator 10 .

[0118] The radiator 10 includes multiple collecting pipes 111 for guiding the refrigerant to flow through the fins of the radiator 10. The collecting pipes 111 can gather the fluids of multiple pipes into one collecting pipe 111, centrally process the output, and simplify the system structure. The gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110 are all pipes used by the radiator 10 to transport fluids. There are multiple gas pipes 130, multiple liquid pipes 140, and multiple collecting pipes 111 of the condenser 110. The gas pipes 130 and the liquid pipes 140 are respectively connected to different collecting pipes 111, which are responsible for transporting the refrigerant.

[0119] The pressure relief structure 150 is mainly used to release pressure under specific conditions, such as when the pressure is too high, to protect the system from damage. A pressure relief section 155 is provided on at least one of the manifold 111, the gas pipe 130 and the liquid pipe 140 of the condenser 110. When the pressure relief section 155 ruptures, a new component can be simply replaced to restore the system to normal operation. The pressure relief section 155 can be a section of at least one of the manifold 111, the gas pipe 130 and the liquid pipe 140 of the condenser 110, or it can be at least one of the manifold 111, the gas pipe 130 and the liquid pipe 140 of the condenser 110.

[0120] In the technical solution of the present application, the strength of the pressure relief section 155 is lower than that of other areas of the radiator 10, that is, under the same pressure conditions, when the pressure in the system exceeds the safety threshold, the pressure relief section 155 will rupture first, thereby releasing the pressure, which helps prevent the entire system from being damaged due to excessive pressure or more serious failures.

[0121] It can be understood that by providing at least one pressure relief section 155 on at least one of the manifold 111, the gas pipe 130 and the liquid pipe 140 of the condenser 110, the fluid can be guided to be released at a specific location, thereby achieving control over the pressure relief process, which helps to reduce the potential impact on the surrounding environment or equipment caused by pressure release.

[0122] In some embodiments, the wall thickness of the pressure relief section 155 is smaller than the wall thickness of other regions of at least one of the gas pipe 130 , the liquid pipe 140 , and the header 111 of the condenser 110 .

[0123] When the inner diameter and material strength are the same, the smaller the wall thickness, the weaker the ability of the pressure relief section 155 to resist deformation or damage. By reducing the wall thickness of the pressure relief section 155, the strength of the pressure relief section 155 can be effectively reduced, so that the strength of the pressure relief section 155 is less than the strength of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control over the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0124] In some embodiments, the strength of the material of the pressure relief section 155 is less than the strength of the material of other regions of at least one of the gas pipe 130 , the liquid pipe 140 , and the header 111 of the condenser 110 .

[0125] When the inner diameter and wall thickness are the same, the smaller the strength of the material, the weaker the ability of the pressure relief section 155 to resist deformation or damage. Using a lower strength material to manufacture the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 less than the strength of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment due to pressure release.

[0126] In some embodiments, the inner diameter of the pressure relief section 155 is larger than the inner diameter of other regions of at least one of the gas pipe 130 , the liquid pipe 140 , or the header 111 of the condenser 110 .

[0127] When the wall thickness and material strength are the same, the larger the inner diameter, the weaker the ability of the pressure relief section 155 to resist deformation or damage. By increasing the inner diameter of the pressure relief section 155, the strength of the pressure relief section 155 can be effectively reduced, so that the strength of the pressure relief section 155 is less than the strength of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control over the pressure relief process and reducing the potential impact on the surrounding environment or equipment due to pressure release.

[0128] In some embodiments, the wall thickness of the pressure relief section 155 is smaller than the wall thickness of at least one other area of ​​the gas pipe 130, the liquid pipe 140, and the collecting pipe 111 of the condenser 110, and the strength of the material of the pressure relief section 155 is smaller than the strength of the material of at least one other area of ​​the gas pipe 130, the liquid pipe 140, and the collecting pipe 111 of the condenser 110.

[0129] The smaller the wall thickness or the weaker the strength of the material, the weaker the ability of the pressure relief section 155 to resist deformation or damage. While using a lower strength material to manufacture the pressure relief section 155, reducing the wall thickness of the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 less than the strength of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0130] In some embodiments, the wall thickness of the pressure relief section 155 is smaller than the wall thickness of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110, and the inner diameter of the pressure relief section 155 is larger than the inner diameter of other areas of at least one of the gas pipe 130, the liquid pipe 140 or the collecting pipe 111 of the condenser 110.

[0131] The smaller the wall thickness or the larger the inner diameter, the weaker the ability of the pressure relief section 155 to resist deformation or damage. While reducing the wall thickness of the pressure relief section 155, increasing the inner diameter of the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 less than the strength of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment due to pressure release.

[0132] In some embodiments, the strength of the material of the pressure relief section 155 is less than the strength of the material of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110, and the inner diameter of the pressure relief section 155 is greater than the inner diameter of other areas of at least one of the gas pipe 130, the liquid pipe 140 or the collecting pipe 111 of the condenser 110.

[0133] The smaller the strength of the material or the larger the inner diameter, the weaker the ability of the pressure relief section 155 to resist deformation or damage. While reducing the strength of the material of the pressure relief section 155, increasing the inner diameter of the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, so that the strength of the pressure relief section 155 is less than the strength of other areas of at least one of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment due to pressure release.

[0134] In some embodiments, the wall thickness of the pressure relief section 155 is smaller than the wall thickness of at least one of the other regions of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110, the strength of the material of the pressure relief section 155 is smaller than the strength of the material of at least one of the other regions of the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110, and the inner diameter of the pressure relief section 155 is larger than the inner diameter of at least one of the other regions of the gas pipe 130, the liquid pipe 140 or the collecting pipe 111 of the condenser 110.

[0135] As the wall thickness decreases, the strength of the material decreases, or the inner diameter increases, the ability of the pressure relief section 155 to resist deformation or damage will weaken. While reducing the wall thickness and material strength of the pressure relief section 155, increasing the inner diameter of the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 less than the strength of at least one other area of ​​the gas pipe 130, the liquid pipe 140, and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0136] During actual operation, the refrigerant absorbs heat and evaporates in the evaporator 120, thereby cooling the air flowing through the evaporator 120. The refrigerant releases heat and condenses into liquid in the condenser 110, and air cooling is used to dissipate heat. When the pressure in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110 gradually increases, the pressure relief section 155 provided on the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110 is more likely to rupture under high pressure.

[0137] It can be understood that the refrigerant is transported through the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110, forming a refrigerant circulation loop as a whole, which can effectively collect and transmit fluids and improve the operating efficiency of the system. The pressure relief section 155 is set on the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110, which can guide the pressure to be released at a specific position, thereby realizing the control of the pressure relief process, protecting the safety and integrity of the system, and not causing harm to personnel or equipment when releasing the pressure.

[0138] In some embodiments, the wall thickness of one of the gas pipe 130 , the liquid pipe 140 and the header 111 of the condenser 110 is smaller than that of the other pipes to form a pressure relief section 155 .

[0139] When the inner diameter and material strength are the same, the smaller the wall thickness, the weaker the ability of the pressure relief section 155 to resist deformation or damage. By reducing the wall thickness of the pressure relief section 155, the strength of the pressure relief section 155 can be effectively reduced, making the strength of the pressure relief section 155 less than the strength of other pipes in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control over the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0140] In some embodiments, the strength of the material of one of the gas pipe 130 , the liquid pipe 140 , and the header 111 of the condenser 110 is lower than that of the other pipes to form the pressure relief section 155 .

[0141] When the inner diameter and wall thickness are the same, the smaller the strength of the material, the weaker the ability of the pressure relief section 155 to resist deformation or damage. Using a lower-strength material to manufacture the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 smaller than the strength of other pipes in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control over the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0142] In some embodiments, the inner diameter of one of the gas pipe 130 , the liquid pipe 140 and the header 111 of the condenser 110 is larger than the other pipes to form a pressure relief section 155 .

[0143] When the wall thickness and material strength are the same, the larger the inner diameter, the weaker the ability of the pressure relief section 155 to resist deformation or damage. By increasing the inner diameter of the pressure relief section 155, the strength of the pressure relief section 155 can be effectively reduced, making the strength of the pressure relief section 155 less than the strength of other pipes in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment due to pressure release.

[0144] In some embodiments, the wall thickness and material strength of one of the gas pipe 130 , the liquid pipe 140 and the header 111 of the condenser 110 are smaller than those of the other pipes to form a pressure relief section 155 .

[0145] The smaller the wall thickness or the weaker the strength of the material, the weaker the ability of the pressure relief section 155 to resist deformation or damage. When using a lower strength material to manufacture the pressure relief section 155, reducing the wall thickness of the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 less than the strength of other pipes in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0146] In some embodiments, one of the gas pipe 130 , the liquid pipe 140 and the header 111 of the condenser 110 has a thinner wall thickness and a larger inner diameter than the other pipes to form a pressure relief section 155 .

[0147] The smaller the wall thickness or the larger the inner diameter, the weaker the ability of the pressure relief section 155 to resist deformation or damage. By reducing the wall thickness of the pressure relief section 155 and increasing the inner diameter of the pressure relief section 155, the strength of the pressure relief section 155 can be effectively reduced, making the strength of the pressure relief section 155 less than the strength of other pipes in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control over the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0148] In some embodiments, the material strength of one of the gas pipe 130 , the liquid pipe 140 and the header 111 of the condenser 110 is smaller than that of the other pipes and the inner diameter is larger than that of the other pipes to form the pressure relief section 155 .

[0149] The smaller the strength of the material or the larger the inner diameter, the weaker the ability of the pressure relief section 155 to resist deformation or damage. While reducing the strength of the material of the pressure relief section 155, increasing the inner diameter of the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 less than the strength of other pipes in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0150] In some embodiments, the wall thickness and material strength of one of the gas pipe 130 , the liquid pipe 140 and the manifold 111 of the condenser 110 are smaller than those of the other pipes and the inner diameter is larger than that of the other pipes to form a pressure relief section 155 .

[0151] As the wall thickness decreases, the strength of the material decreases, or the inner diameter increases, the ability of the pressure relief section 155 to resist deformation or damage will weaken. While reducing the wall thickness and material strength of the pressure relief section 155, increasing the inner diameter of the pressure relief section 155 can effectively reduce the strength of the pressure relief section 155, making the strength of the pressure relief section 155 less than the strength of other pipes in the gas pipe 130, the liquid pipe 140 and the collecting pipe 111 of the condenser 110. In this way, the pressure relief section 155 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact on the surrounding environment or equipment caused by pressure release.

[0152] The following describes the embodiments of the present application in detail from three different implementation perspectives.

[0153] Example 1: The pressure relief structure 150 is a protective sheet 151 located on the cover plate 122.

[0154] In this embodiment, the radiator 10 includes a condenser 110 , an evaporator 120 , an air pipe 130 and a liquid pipe 140 .

[0155] The condenser 110 and the evaporator 120 are arranged up and down, the evaporator 120 is arranged vertically, and the condenser 110 is arranged slightly inclined. There are pipelines connecting the two. The gas pipe 130 is connected to the outlet of the evaporator 120 and the inlet of the condenser 110 respectively, and the liquid pipe 140 is connected to the inlet of the evaporator 120 and the outlet of the condenser 110 respectively, forming a refrigerant circulation loop as a whole.

[0156] The evaporator 120 includes a flow channel plate 121 and a cover plate 122 . A flow channel opening 123 communicating with the gas pipe 130 and the liquid pipe 140 is formed on a first surface of the flow channel plate 121 . The cover plate 122 is mounted on the first surface of the flow channel plate 121 .

[0157] The cover plate 122 may be provided with a pressure relief structure 150 . The pressure relief structure 150 may have various structural forms, including but not limited to:

[0158] The protective sheet 151 is fitted with the cover plate 122 and closes the pressure relief port 124 , and the connection strength of at least one connection position between the protective sheet 151 and the cover plate 122 is less than the strength of the cover plate 122 itself.

[0159] The protective sheet 151 is connected to the cover plate 122 via a threaded connector 152 , and the threaded connector 152 has an installation torque as a target value.

[0160] The protection sheet 151 is sealed to the cover plate 122 .

[0161] During actual operation, the refrigerant absorbs heat and evaporates in the evaporator 120, thereby cooling the air flowing through the evaporator 120. The refrigerant releases heat and condenses into liquid in the condenser 110, and air cooling is used for heat dissipation. The protective sheet 151 is connected to the cover plate 122 through a threaded connector 152, and a sealant 153 or a sealing strip is provided between the protective sheet 151 and the cover plate 122, which can close the pressure relief port 124. When the pressure exceeds a certain threshold, the protective sheet 151 breaks before the cover plate 122, and the pressure at the flow channel port 123 is released through the pressure relief port 124.

[0162] By providing a protective sheet 151 on the cover plate 122, leakage of liquid or gas can be prevented, and the pressure can be released at the pressure relief port 124, thereby achieving control over the pressure relief process. No harm will be caused to personnel or equipment when the pressure is released, reducing the potential impact of pressure release on the surrounding environment or equipment, and protecting the safety and integrity of the system.

[0163] Example 2: The pressure relief structure 150 is located in the target area 154 of the cover plate 122

[0164] In this embodiment, the radiator 10 includes a condenser 110 , an evaporator 120 , an air pipe 130 and a liquid pipe 140 .

[0165] The condenser 110 and the evaporator 120 are arranged up and down, the evaporator 120 is arranged vertically, and the condenser 110 is arranged slightly inclined. There are pipelines connecting the two. The gas pipe 130 is connected to the outlet of the evaporator 120 and the inlet of the condenser 110 respectively, and the liquid pipe 140 is connected to the inlet of the evaporator 120 and the outlet of the condenser 110 respectively, forming a refrigerant circulation loop as a whole.

[0166] The evaporator 120 includes a flow channel plate 121 and a cover plate 122 . A flow channel opening 123 communicating with the gas pipe 130 and the liquid pipe 140 is formed on a first surface of the flow channel plate 121 . The cover plate 122 is mounted on the first surface of the flow channel plate 121 .

[0167] The cover plate 122 may be provided with a pressure relief structure 150 . The pressure relief structure 150 may have various structural forms, including but not limited to:

[0168] The pressure relief structure 150 includes a target area 154 disposed on the cover plate 122 , and the target area 154 is opposite to the flow channel opening 123 .

[0169] During actual operation, the refrigerant absorbs heat and evaporates in the evaporator 120, thereby cooling the air flowing through the evaporator 120. The refrigerant releases heat and condenses into liquid in the condenser 110, and air cooling is used for heat dissipation. The target area 154 is designed to be opposite to the flow channel opening 123. The flow rate of the fluid at the flow channel opening 123 is faster, and the pressure also reaches the maximum accordingly. When the target area 154 ruptures under high pressure, the pressure at the flow channel opening 123 is released through the target area 154.

[0170] By setting a target area 154 on the cover plate 122 and making the target area 154 face the flow channel opening 123, the pressure can be guided to be released at the target area 154, thereby achieving control over the pressure relief process. When the pressure is released, no harm will be caused to personnel or equipment, reducing the potential impact of pressure release on the surrounding environment or equipment, and protecting the safety and integrity of the system.

[0171] Example 3: The pressure relief structure 150 is a pressure relief section 155 located on the gas pipe 130, the liquid pipe 140 and the manifold 111 of the condenser 110.

[0172] In this embodiment, the radiator 10 includes a condenser 110 , an evaporator 120 , an air pipe 130 and a liquid pipe 140 .

[0173] The condenser 110 and the evaporator 120 are arranged up and down, the evaporator 120 is arranged vertically, and the condenser 110 is arranged slightly inclined. There are pipelines connecting the two. The gas pipe 130 is connected to the outlet of the evaporator 120 and the inlet of the condenser 110 respectively, and the liquid pipe 140 is connected to the inlet of the evaporator 120 and the outlet of the condenser 110 respectively, forming a refrigerant circulation loop as a whole.

[0174] A pressure relief structure 150 may be provided on the air pipe 130, the liquid pipe 140 or the manifold 111 of the condenser 110. The pressure relief structure 150 includes a pressure relief section 155 provided on the manifold 111 of the condenser 110, at least one of the air pipe 130 and the liquid pipe 140. The pressure relief section 155 may be at least one of the air pipe 130, the liquid pipe 140 and the manifold 111 of the condenser 110, or may be a part of at least one of the air pipe 130, the liquid pipe 140 and the manifold 111 of the condenser 110. The pressure relief section 155 has various structural forms, and the strength of the pressure relief section 155 is less than the strength of other areas of the radiator 10.

[0175] During actual operation, the refrigerant absorbs heat and evaporates in the evaporator 120, thereby cooling the air flowing through the evaporator 120. The refrigerant releases heat and condenses into liquid in the condenser 110, and heat is dissipated by air cooling. The strength of the material of the pressure relief section 155 is less than that of the material in other areas of the radiator 10. When the pressure in the radiator 10 gradually increases, the pressure relief section 155 is more likely to rupture under high pressure.

[0176] By providing a pressure relief section 155 on the gas pipe 130, the liquid pipe 140 or the manifold 111 of the condenser 110, the pressure can be guided to be released at a specific location, thereby achieving control over the pressure relief process, protecting the safety and integrity of the system, and not causing harm to personnel or equipment when releasing the pressure.

[0177] The present application also provides an electrical device 1, such as Figure 1 and Figure 2 As shown, the electrical device 1 includes a heat sink 10 and a power device 20 .

[0178] According to the electrical equipment 1 provided in the embodiment of the present application, the power device 20 can be a power cabinet such as a photovoltaic inverter and an energy storage converter, which has the characteristics of large heat generation, concentrated heat generation and large heat flux density. By adopting phase change heat dissipation, efficient cooling of the power device 20 can be achieved, solving the heat dissipation bottleneck problem of traditional heat dissipation methods during high-load operation, and providing strong guarantee for the stable operation of the electrical equipment 1.

[0179] In some embodiments, the power device 20 is mounted on the evaporator 120 .

[0180] In the technical solution of the present application, the evaporator 120 can be designed to be in close contact with the power device 20 or in indirect contact through a heat conduction medium. The heat generated by the power device 20 can be transferred to the evaporator 120 through direct contact or a heat conduction medium, and then the heat is transferred by the evaporator 120.

[0181] During actual operation, the power device 20 generates a large amount of heat during operation, and effective heat dissipation measures are required to ensure the stable operation of the power device 20. The evaporator 120 can absorb heat from the power device 20 and transfer it to other media, thereby achieving efficient and stable heat transfer.

[0182] It can be understood that the evaporator 120 effectively reduces the temperature of the power device 20 by absorbing the heat generated by the power device 20 and transferring it to other media, which helps to ensure the stable operation of the power device 20 and prevent performance degradation or damage due to overheating. Through efficient heat transfer, the evaporator 120 can keep the power device 20 at a lower operating temperature, thereby improving its operating efficiency and energy efficiency.

[0183] In some embodiments, as Figure 1 and Figure 2 As shown, the electrical device 1 further includes:

[0184] The box body 30 forms a first cavity 310 and a second cavity 320 that are isolated from each other. The power device 20 is installed in the first cavity 310, the heat sink 10 is installed in the second cavity 320, and the pressure relief structure 150 is provided on the side of the heat sink 10 away from the first cavity 310.

[0185] In the technical solution of the present application, the box body 30 is a closed structure for accommodating and separating different components. The first cavity 310 and the second cavity 320 can be isolated from each other to ensure that heat and gas between the two are not exchanged at will. Suitable materials and sealing technologies can be used to manufacture the box body 30 to ensure the isolation effect between the first cavity 310 and the second cavity 320. For example, it can be made of metal. The first cavity 310 and the second cavity 320 are respectively used to accommodate different components and realize different functions. The first cavity 310 is mainly used to install the power device 20, while the second cavity 320 is used to install the radiator 10. The heat dissipation surface of the radiator 10 faces the first cavity 310, that is, toward the power device 20. This design can ensure that the radiator 10 can directly and effectively absorb the heat generated by the power device 20. The pressure relief structure 150 is located on the side of the radiator 10 away from the first cavity 310 to prevent leaked substances from affecting the power device 20 in the first cavity 310 and causing secondary damage.

[0186] During actual operation, the gas-liquid conversion process is often accompanied by a significant increase in working pressure, so there is an explosion risk that cannot be ignored. As heat is transferred and the radiator 10 works, the radiator 10 located inside the second chamber 320 will produce pressure and temperature changes. When the internal pressure of the radiator 10 exceeds a specific pressure threshold, the pressure relief structure 150 will automatically open, allowing gas or liquid to be discharged from the radiator 10 into the second chamber 320, which can prevent the radiator 10 from exploding due to excessive pressure and other destructive phenomena.

[0187] It can be understood that through the heat transfer between the power device 20 and the heat sink 10 and the effective heat dissipation of the heat sink 10, the entire system achieves efficient heat management, ensures that the power device 20 can operate at a suitable temperature, and improves its working stability and reliability.

[0188] In some embodiments, the housing 30 may have a protective structure in an area facing the pressure relief structure 150 .

[0189] In the technical solution of the present application, the design of the protective structure may include guide channels, protective nets and baffles, etc., which can guide or block the substances released from the pressure relief structure 150 to ensure that they do not directly dissipate to the outside world, providing additional safety protection for the entire system. Especially in a high-pressure environment, it can effectively prevent the injection phenomenon that may be caused by pressure relief, protect the surrounding personnel and equipment, and the use of the protective structure also reduces the potential pollution of the environment by the internal substances of the system, prevents the direct discharge of harmful substances, and helps to maintain a clean and safe working environment.

[0190] During actual operation, when excessive pressure is generated inside the system due to heat accumulation or other reasons, the pressure relief structure 150 will work as designed, releasing part of the pressure to maintain the stability of the system. The box body 30 is provided with a protective structure in the area facing the pressure relief structure 150, which can prevent liquid, gas or particulate matter from being directly sprayed to the outside of the box body 30 during the pressure relief process, causing harm to the surrounding environment or personnel.

[0191] It is understandable that the provision of a protective structure in the area of ​​the box body 30 facing the pressure relief structure 150 not only enhances the safety of the system, but also protects the integrity of the working environment and equipment, further improving the reliability of the entire system.

[0192] The embodiment of the present application further provides a pressure relief device, which is applied to the radiator 10 and is configured to be breakable to relieve pressure, for example, it may be a pressure relief structure 150 .

[0193] In actual working procedures, the gas-liquid conversion process is often accompanied by a significant increase in working pressure, so there is an explosion risk that cannot be ignored. When the internal pressure exceeds a specific pressure threshold, the pressure relief structure 150 can respond quickly and release the pressure in time to prevent the pressure from continuing to rise, thereby avoiding secondary damage to the entire machine caused by the explosion of the radiator 10 under extreme working conditions. At the same time, the pressure relief structure 150 has good sealing properties, which can prevent liquid or gas leakage and ensure that no harm is caused to personnel or equipment when the pressure is released.

[0194] It is understandable that by designing a weak structure as the pressure relief structure 150, pressure can be released at a specific point under certain conditions, thereby avoiding secondary damage to the entire machine caused by the radiator 10 exploding under extreme working conditions.

[0195] In some embodiments, the pressure relief device includes: a protective sheet 151, the radiator is provided with a pressure relief port 124, the pressure relief port 124 is connected to the medium flow channel of the radiator 10, the protective sheet 151 closes the pressure relief port 124, and the connection strength of the protective sheet 151 at at least one point on the radiator 10 is less than the strength of other areas of the radiator 10.

[0196] The pressure relief port 124 is connected to the medium flow channel of the radiator 10. When the fluid flows in the flow channel, its state is vigorous turbulence. The medium flow channel of the radiator 10 is a key channel for the fluid to enter and flow out. The protective sheet 151 closes the pressure relief port 124. At the same time, the connection strength of the protective sheet 151 at at least one point on the radiator 10 is less than the strength of other areas of the radiator 10. For example, the connection between the protective sheet 151 and the cover plate 122 can be achieved by spot welding, gluing or mechanical connection. At the same time, the connection strength can be controlled by adjusting the number, distribution and connection method of the connection points. When the pressure exceeds a certain threshold, the protective sheet 151 will break first, thereby realizing the pressure relief function, and the rupture of the protective sheet 151 is more controllable, and has less impact on the overall system.

[0197] It can be understood that by providing a protective sheet 151 type pressure relief device, the rupture of the pressure relief device can be made more controllable, reducing the impact on the overall system.

[0198] In some embodiments, the pressure relief device includes: a target area 154 of the radiator 10 , wherein the strength of the target area 154 is less than the strength of other areas of the radiator 10 , and the target area 154 faces the medium flow channel of the radiator 10 .

[0199] When the fluid flows in the flow channel, its state is vigorous turbulence. The medium flow channel of the radiator 10 is the key channel for the fluid to enter and flow out. When the system operates normally, the internal pressure gradually increases. The other parts of the radiator 10 except the target area 154 are relatively strong and the pressure distribution is relatively uniform. The target area 154 is a weak link designed on the radiator 10, and its structural strength is lower than that of other parts of the radiator 10. When the internal pressure of the system reaches a critical value, the target area 154 is more likely to rupture, thereby releasing the pressure.

[0200] It can be understood that by setting up a target area 154 type pressure relief device, the potential impact of pressure release on the surrounding environment or equipment can be reduced, thereby improving the safety of the entire system.

[0201] In some embodiments, the intensity of the target area 154 can be made smaller than the intensity of other areas of the heat sink 10 by the following methods:

[0202] In example one, the wall thickness of the target area 154 is smaller than the wall thickness of other areas of the heat sink 10 .

[0203] When the inner diameter and material strength are the same, the smaller the wall thickness, the weaker the target area 154's ability to resist deformation or damage. By reducing the wall thickness of the target area 154, the strength of the target area 154 can be effectively reduced, making the strength of the target area 154 less than the strength of other areas of the radiator 10.

[0204] When the strength of the target area 154 is less than the strength of other areas of the radiator 10, the target area 154 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact of pressure release on the surrounding environment or equipment.

[0205] In a second example, the strength of the material of the target area 154 is less than the strength of the material of other areas of the heat sink 10 .

[0206] When the inner diameter and wall thickness are the same, the smaller the strength of the material, the weaker the target area 154's ability to resist deformation or damage. Using a lower strength material to manufacture the target area 154 can effectively reduce the strength of the target area 154, making the strength of the target area 154 lower than the strength of other areas of the radiator 10.

[0207] When the strength of the target area 154 is less than the strength of other areas of the radiator 10, the target area 154 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact of pressure release on the surrounding environment or equipment.

[0208] In example three, the inner diameter of the target area 154 is larger than the inner diameters of other areas of the heat sink 10 .

[0209] When the wall thickness and material strength are the same, the larger the inner diameter, the weaker the target area 154's ability to resist deformation or damage. By increasing the inner diameter of the target area 154, the strength of the target area 154 can be effectively reduced, making the strength of the target area 154 less than the strength of other areas of the radiator 10.

[0210] When the strength of the target area 154 is less than the strength of other areas of the radiator 10, the target area 154 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact of pressure release on the surrounding environment or equipment.

[0211] In the fourth example, the wall thickness of the target region 154 is smaller than the wall thickness of other regions of the heat sink 10 , and the strength of the material of the target region 154 is smaller than the strength of the material of other regions of the heat sink 10 .

[0212] The smaller the wall thickness or the weaker the strength of the material, the weaker the target area 154's ability to resist deformation or damage. While using a lower strength material to manufacture the target area 154, reducing the wall thickness of the target area 154 can effectively reduce the strength of the target area 154, making the strength of the target area 154 less than the strength of other areas of the radiator 10.

[0213] When the strength of the target area 154 is less than the strength of other areas of the radiator 10, the target area 154 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact of pressure release on the surrounding environment or equipment.

[0214] In example five, the wall thickness of the target area 154 is smaller than the wall thickness of other areas of the heat sink 10 , and the inner diameter of the target area 154 is larger than the inner diameter of other areas of the heat sink 10 .

[0215] The smaller the wall thickness or the larger the inner diameter, the weaker the target area 154's ability to resist deformation or damage. While reducing the wall thickness of the target area 154, increasing the inner diameter of the target area 154 can effectively reduce the strength of the target area 154, making the strength of the target area 154 less than the strength of other areas of the radiator 10.

[0216] When the strength of the target area 154 is less than the strength of other areas of the radiator 10, the target area 154 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact of pressure release on the surrounding environment or equipment.

[0217] Example six: The strength of the material of the target area 154 is less than the strength of the material of the other areas of the heat sink 10 , and the inner diameter of the target area 154 is greater than the inner diameters of the other areas of the heat sink 10 .

[0218] The smaller the strength of the material or the larger the inner diameter, the weaker the target area 154's ability to resist deformation or damage. While reducing the strength of the material of the target area 154, increasing the inner diameter of the target area 154 can effectively reduce the strength of the target area 154, making the strength of the target area 154 less than the strength of other areas of the radiator 10.

[0219] When the strength of the target area 154 is less than the strength of other areas of the radiator 10, the target area 154 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact of pressure release on the surrounding environment or equipment.

[0220] Example seven: The wall thickness of the target area 154 is smaller than the wall thickness of other areas of the radiator 10 , the strength of the material of the target area 154 is smaller than the strength of the material of other areas of the radiator 10 , and the inner diameter of the target area 154 is larger than the inner diameter of other areas of the radiator 10 .

[0221] As the wall thickness decreases, the strength of the material decreases, or the inner diameter increases, the ability of the target area 154 to resist deformation or damage will weaken. While reducing the wall thickness and material strength of the target area 154, increasing the inner diameter of the target area 154 can effectively reduce the strength of the target area 154, making the strength of the target area 154 less than the strength of other areas of the radiator 10.

[0222] When the strength of the target area 154 is less than the strength of other areas of the radiator 10, the target area 154 is more likely to rupture when the pressure exceeds the critical pressure, and the pressure can be guided to be released at a specific location, thereby achieving control of the pressure relief process and reducing the potential impact of pressure release on the surrounding environment or equipment.
