Technical Field

[0001] [Cross-reference to Related Applications] This application is filed based on a Chinese patent application with an application number of 202223253590.8 and an application date of December 06, 2022, and claims the priority of this Chinese patent application. All the contents of this Chinese patent application are incorporated herein by reference into this application.

[0002] This application relates to the field of battery technology, specifically to a thermal management system used in batteries, batteries, and power-consuming devices.

Background Art

[0003] In related technologies, in order to avoid the battery temperature being too high or too low, a thermal management system is generally installed to adjust the battery temperature. The thermal management system has pipelines for the flow of a heat exchange medium. During the long-term use process, improper use or other reasons may cause a liquid leakage phenomenon due to the corrosion of the pipelines. Therefore, it is necessary to regularly inspect or detect the corrosion status of the pipelines of the thermal management system, thereby facilitating timely maintenance.

[0004] However, in related technologies, during the process of inspecting or detecting the corrosion status of the pipelines of the thermal management system, it may cause damage to the pipelines of the thermal management system and also increase the maintenance cost. How to inspect or detect the corrosion status of the pipelines of the thermal management system, facilitate inspection and maintenance, and at the same time reduce the maintenance cost is an urgent problem to be solved.

Summary of the Invention

[0005] Embodiments of this application provide a thermal management system used in batteries, batteries, and power-consuming devices, which can realize inspecting or detecting the corrosion status of the pipelines of the thermal management system without causing damage to the thermal management system, facilitate inspection and maintenance, and at the same time reduce the maintenance cost.

[0006] According to a first aspect, an embodiment of the present application provides a thermal management system for use in a battery, the thermal management system body, the thermal management system body includes a medium conduit for the flow of a heat exchange medium, the medium conduit having an inlet end and an outlet end, and a removable monitoring pipe provided at least one of the inlet end and the outlet end.

[0007] In the above proposed technology, a removable monitoring pipe is provided at least one of the inlet and outlet ends of the media conduit of the thermal management system. As the heat exchange medium circulates and flows through the thermal management system, the heat exchange medium flows not only through the media conduit but also through the monitoring pipe. Since the monitoring pipe and the inlet or outlet end of the media conduit are detachably connected, if it is necessary to inspect or detect the corrosion status of the media conduit of the thermal management system, the monitoring pipe can be removed from the inlet or outlet end of the media conduit. For example, the corrosion status inside the monitoring pipe can be detected or inspected by the opening of the monitoring pipe. By inspecting or detecting the corrosion status inside the monitoring pipe, the corrosion status of the conduit in the thermal management system can be obtained. This enables inspection or detection of the corrosion status of the conduit in the thermal management system without causing damage to the thermal management system, facilitating inspection and maintenance while simultaneously reducing maintenance costs.

[0008] In some embodiments, the material of at least a portion of the inner wall of the monitoring pipe is the same as the material of the media conduit. In this way, the flow environment in the monitoring pipe of the heat exchange medium can be made to resemble or identical to the flow environment in the media conduit of the heat exchange medium, thereby allowing the corrosion condition in the monitoring pipe to respond more accurately to the overall corrosion condition of the conduit of the thermal management system.

[0009] In some embodiments, the monitoring pipe is inserted into the media conduit. Inserting the monitoring pipe into the media conduit makes it easier to attach and detach the monitoring pipe.

[0010] In some embodiments, the axial ends of the monitoring pipe have a first and a second pipe opening, respectively, and the inlet or outlet end is inserted into the monitoring pipe through the first pipe opening. Inserting the inlet or outlet end of the media conduit into the monitoring pipe facilitates the insertion operation of the monitoring pipe and the media conduit.

[0011] In some embodiments, a first sealing material is provided between the inner wall of the monitoring pipe and the outer wall of the media conduit, or between the outer wall of the monitoring pipe and the inner wall of the media conduit. By installing the first sealing material between the monitoring pipe and the media conduit, a seal is achieved over the fitting gap between the monitoring pipe and the media conduit, preventing leakage at the fitting point between the monitoring pipe and the media conduit as the heat exchange medium flows through the monitoring pipe.

[0012] In some embodiments, the axial ends of the monitoring pipe have a first and a second pipe opening, respectively, and the inlet or outlet end is inserted into the monitoring pipe through the first pipe opening. The first sealing material is fixed to the inner circumferential wall of the monitoring pipe and surrounds the inlet or outlet end. By fixing the first sealing material to the inner circumferential wall of the monitoring pipe, when the inlet or outlet end of the media conduit is inserted into the monitoring pipe, the first sealing material is pressed and deformed through the outer circumferential wall of the media conduit, thereby easily inserting the inlet or outlet end of the media conduit into the monitoring pipe and simultaneously easily sealing the two.

[0013] In some embodiments, a first receiving groove is formed in the inner circumferential wall of the monitoring pipe, the first receiving groove is formed in an annular shape extending along the circumferential direction of the monitoring pipe, and the first sealing material is housed in the first receiving groove. By providing a receiving groove for housing the first sealing material in the inner circumferential wall of the monitoring pipe, the installation and fixing of the first sealing material is facilitated, and a positional regulating effect on the first sealing material can be achieved. In this way, movement of the first sealing material due to frictional force between the media conduit and the first sealing material can be avoided during the process of attaching and detaching the monitoring pipe, thereby ensuring that the first sealing material is held in the set position, and thus the sealing effect of the first sealing material can be guaranteed.

[0014] In some embodiments, the first sealing material includes a first guide portion and a first sealing portion arranged along the axial direction of the monitoring pipe, wherein the first guide portion is located on one side of the first sealing portion adjacent to the first pipe opening, the inner circumference of the first guide portion defines a first guide passage, the cross-sectional area of ​​the first guide passage gradually decreases in the insertion direction of the inlet or outlet end, and the first sealing portion is fitted in contact with the outer circumferential wall of the inlet or outlet end. By setting the portion of the first sealing material near the first pipe opening in a flared shape, the guiding action of the first guide passage allows the inlet or outlet end of the media conduit to be quickly inserted into the first sealing material during the process of inserting the inlet or outlet end of the media conduit into the first sealing material, reducing insertion resistance, further simplifying and facilitating the insertion operation of the media conduit and the monitoring pipe, and ensuring the sealing effect of the first sealing material by bringing the first sealing portion of the first sealing material into contact with the outer circumferential wall of the media conduit.

[0015] In some embodiments, a first sealing projection is formed on the outer circumferential wall of the inlet or outlet end, the first sealing projection is formed in an annular shape extending along the circumferential direction of the media conduit, and the first sealing projection abuts against the first sealing material. By installing the first sealing projection on the outer circumferential wall of the inlet or outlet end of the media conduit, when the inlet or outlet end of the media conduit is inserted into the monitoring pipe, the first sealing projection presses against the first sealing material located inside the monitoring pipe, causing the outer circumferential wall of the inlet or outlet end of the media conduit to fit more tightly with the first sealing material fixed inside the monitoring pipe, thereby further improving the sealing effect.

[0016] In some embodiments, the thermal management system further includes an external conduit, the monitoring pipe being connected between the external conduit and the medium conduit to form a circulation path, and the monitoring pipe being detachably connected to the external conduit. By detachably connecting the monitoring pipe to the external conduit located outside the battery of the thermal management system, the entire monitoring pipe can thus be removed from the thermal management system, thereby making it easier to inspect or detect the corrosion condition inside the monitoring pipe.

[0017] In some embodiments, the monitoring pipe includes a pipe body and a window cover, wherein a monitoring window is formed in the outer wall of the pipe body, the monitoring window penetrates the inner wall of the pipe body, the window cover covers the monitoring window, the window cover is removable and / or the window cover is a transparent member. By installing a monitoring window in the outer wall of the monitoring pipe, the number of routes for inspecting or detecting the monitoring pipe can be increased, making the inspection or detection of the corrosion status of the monitoring pipe more convenient, accurate, and comprehensive.

[0018] In some embodiments, the material of the tubing is the same as the material of the media conduit, and / or the material of the window cover is the same as the material of the media conduit. In this way, the flow environment in the monitoring tube of the heat exchange medium can be made to resemble or identical to the flow environment in the media conduit of the heat exchange medium, thereby allowing the corrosion condition in the monitoring tube to respond more accurately to the overall corrosion condition of the conduit of the thermal management system.

[0019] In some embodiments, the inner wall surface of the window cover is installed coplanar with the inner wall surface of the pipe. In this way, the flow environment in the monitoring pipe of the heat exchange medium can be made to resemble or identical to the flow environment in the medium pipeline of the heat exchange medium, thereby allowing the corrosion status in the monitoring pipe to respond more accurately to the overall corrosion status of the pipeline of the thermal management system.

[0020] In some embodiments, the outer surface of the window cover is installed in the same plane as the outer surface of the pipe. This prevents the window cover from protruding from the pipe and occupying extra space, thereby making the structure more compact and preventing the formation of a large step between the window cover and the pipe that could injure workers or other components.

[0021] In some embodiments, a third sealing material is provided between the window cover and the pipe. By installing the third sealing material between the window cover and the pipe, the fitting gap between the window cover and the pipe can be sealed, and leakage of the heat exchange medium from the fitting area between the window cover and the pipe can be prevented as the heat exchange medium flows through the monitoring pipe.

[0022] In some embodiments, the window cover and the pipe are connected by fasteners. The fasteners can be used to attach and secure the window cover to the observation window area of ​​the pipe, making it easy to attach and detach the window cover and ensuring the strength of the connection between the window cover and the pipe.

[0023] In some embodiments, the monitoring window is formed in a stepped hole, and the outer periphery wall of the window cover is formed in a stepped shape to fit the stepped hole. By installing the monitoring window in a stepped hole and setting the outer periphery wall of the window cover in a stepped shape to fit the stepped hole, the fitting area between the window cover and the pipe can be increased, and at the same time, the installation and fixing of the window cover can be facilitated.

[0024] In some embodiments, the monitoring window includes a first hole and a second hole arranged along the thickness direction of the pipe, the cross-sectional area of ​​the first hole being larger than that of the second hole, the first hole being located radially outward of the second hole, and a stepped surface being formed between the first and second holes; the window cover includes a cover plate and a boss, the boss being provided on the inside of the cover plate, the cover plate being housed in the first hole and in contact with the stepped surface, and the boss being housed in the second hole. By setting the monitoring window as a stepped hole that is larger on the outside and smaller on the inside, the corrosion condition inside the pipe can be easily inspected or detected by this monitoring window; and by setting the window cover as a structure with a boss, the portion of the cover plate located on the outer circumference side of the boss supports and contacts the stepped surface inside the monitoring window, improving the mounting stability of the window cover; and at the same time, the stepped surface can support the cover plate during the process of attaching and detaching the window cover, thus facilitating the attachment and detachment of the window cover.

[0025] In some embodiments, a third sealing material is provided between the cover plate and the stepped surface. By installing the third sealing material between the cover plate of the window cover and the stepped surface of the pipe, the fitting gap between the window cover and the pipe can be sealed, preventing the heat exchange medium from leaking from the fitting area between the window cover and the pipe as the heat exchange medium flows through the monitoring pipe. Furthermore, by installing the third sealing material between the cover plate and the stepped surface, the stepped surface can provide support for the third sealing material, facilitating the installation and fixing of the third sealing material.

[0026] In some embodiments, a third receiving concave groove is formed on the stepped surface. The third receiving concave groove is formed in an annular shape extending along the circumferential direction of the first hole portion. The third sealing member is received in the third receiving concave groove. By providing the third receiving concave groove for receiving the third sealing member on the stepped surface, the attachment and fixation of the third sealing member are facilitated. The third receiving concave groove can perform a position restricting function on the third sealing member, preventing the third sealing member from moving and affecting the sealing effect, thereby ensuring the sealing effect of the third sealing member.

[0027] In some embodiments, a first connection hole is formed in the cover plate, and a second connection hole is formed in the stepped surface. The fastener is inserted through the first connection hole and the second connection hole, thereby fixing the window cover to the pipe body. By passing the fastener through the cover plate and penetrating the pipe body through the stepped surface, the cover plate can be reliably attached to the monitoring window location of the pipe body. Since the fastener penetrates the pipe body from the stepped surface of the pipe body, the attachment of the fastener is facilitated.

[0028] In some embodiments, the second connection hole is a blind hole. By setting the second connection hole on the stepped surface of the installed pipe body as a blind hole and the second connection hole penetrating the inner peripheral wall of the pipe body, it is possible to avoid the heat exchange medium flowing in the monitoring pipe from leaking from the fitting location between the second connection hole and the fastener, and improve the assembly sealing performance between the window cover and the pipe body.

[0029] According to a second aspect, an embodiment of the present application further provides a battery, which includes at least one battery cell and the above-mentioned thermal management system for regulating the temperature of the battery cell. Thereby, by adopting the above-mentioned thermal management system, it is possible to inspect or detect the corrosion status of the pipeline of the thermal management system without causing damage to the thermal management system, facilitating inspection and maintenance, and at the same time reducing the maintenance cost.

[0030] In some embodiments, the battery includes a housing, the battery cell and the main body of the thermal management system are both provided inside the housing, the inlet end and the outlet end are both located outside the housing, and the monitoring pipe is located outside the housing. Installing the monitoring pipe outside the housing of the battery eliminates the need to remove the housing of the battery when it is necessary to remove the monitoring pipe from the battery for corrosion inspection or detection, making it easier to inspect or detect the corrosion condition of the pipeline of the thermal management system.

[0031] According to a third aspect, embodiments of the present application further provide a power consumption device, which includes the above battery, and the battery is used to provide electrical energy to the power consumption device. Thereby, by adopting the above thermal management system, it is possible to inspect or detect the corrosion condition of the pipeline of the thermal management system without causing damage to the thermal management system, making inspection and maintenance easier and reducing maintenance costs at the same time.

It should be understood that the dimensions such as thickness, aspect ratio of various components in the embodiments of this application shown in the drawings, and the dimensions such as thickness, aspect ratio of the overall assembly device, are illustrative only and do not constitute any limitation of this application.

[0041] The term "multiple" as it appears in this application refers to two or more (including two).

[0042] In this application, battery 300 refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. Here, the battery 300 can be directly configured with multiple battery cells connected in series, parallel, or series-parallel, where series-parallel means that the multiple battery cells have both series and parallel connections. Alternatively, multiple battery cells may be connected in series, parallel, or series-parallel to form a battery module, and then the multiple battery modules may be connected in series, parallel, or series-parallel to form battery 300. For example, battery 300 as referred to in this application may include a battery module or a battery pack, etc.

[0043] In this application, the battery cell may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, and the embodiments of this application are not limited thereto. The battery cell may be cylindrical, flattened, rectangular, or have other shapes, and the embodiments of this application are not limited thereto. Generally, battery cells are classified into three types based on their packaging: cylindrical battery cells, rectangular battery cells, and pouch battery cells, and the embodiments of this application are not limited thereto.

[0044] For example, a battery cell may include a battery case, an electrode assembly, and an electrolyte, the battery case being used to house the electrode assembly and the electrolyte. The electrode assembly consists of a positive electrode plate, a negative electrode plate, and a separator. The battery cell operates primarily through the movement of metal ions between the positive and negative electrode plates. The positive electrode plate includes a positive electrode current collector and a positive electrode active material layer, the positive electrode active material layer being coated on the surface of the positive electrode current collector, a positive electrode current collector without the positive electrode active material layer protruding from a positive electrode current collector with the positive electrode active material layer, and a positive electrode current collector without the positive electrode active material layer being a positive electrode tab. Taking a lithium-ion battery as an example, the material of the positive electrode current collector may be aluminum, and the positive electrode active material may be lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide, etc.

[0045] The negative electrode plate includes a negative electrode current collector and a negative electrode active material layer. The negative electrode active material layer is coated on the surface of the negative electrode current collector. A negative electrode current collector without the negative electrode active material layer protrudes from a negative electrode current collector with the negative electrode active material layer, and a negative electrode current collector without the negative electrode active material layer is designated as a negative electrode tab. The material of the negative electrode current collector may be copper, and the negative electrode active material may be carbon or silicon, etc. Multiple positive electrode tabs are stacked to prevent melting even when a large current is applied. Multiple negative electrode tabs are stacked.

[0046] The separator material may be PP (polypropylene) or PE (polyethylene), etc. The electrode assembly may have a wound structure or a laminated structure, and the embodiments of this application are not limited to these.

[0047] Some batteries 300 may include a housing 301 for packaging one or more battery cells or multiple battery modules, the housing 301 which can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells. Of course, some batteries 300 do not include the housing 301 and are installed directly in the battery mounting cabin of the power consumption device 1000.

[0048] To prevent the battery cells from being too hot or too cold, to ensure the stable operation of the entire battery 300, and to give the battery 300 a long service life, a thermal management system is employed to regulate the temperature of the battery cells. The thermal management system has conduits through which a heat exchange medium flows, and as the heat exchange medium flows through the conduits of the thermal management system, it can carry away the heat generated by the battery cells or heat the battery cells, thereby achieving temperature regulation for the battery cells.

[0049] During the long-term use of Battery 300, improper use or other reasons may cause leakage due to corrosion of the thermal management system's piping. Therefore, it is necessary to periodically inspect or detect the corrosion status of the thermal management system's piping, thereby facilitating timely maintenance.

[0050] In related technologies, the process of inspecting or detecting corrosion in the piping of a thermal management system can cause damage to the piping, requiring repairs. This not only makes it difficult to detect or inspect corrosion in the piping of a thermal management system, but also increases maintenance costs.

[0051] Based on this, in order to facilitate inspection and maintenance of the piping of the thermal management system and at the same time reduce maintenance costs, the applicant has diligently researched and proposed a thermal management system for a battery 300, which includes a thermal management system body and a monitoring pipe 100, the thermal management system body including a medium piping 200 through which a heat exchange medium flows, the medium piping 200 having an inlet end 51 and an outlet end 52, and a removable monitoring pipe 100 is provided at least one of the inlet end 51 and the outlet end 52.

[0052] In the proposed technology of this application, a removable monitoring pipe 100 is provided at least one of the inlet end 51 and outlet end 52 of the media conduit 200 of the thermal management system. As the heat exchange medium circulates and flows through the thermal management system, the heat exchange medium flows not only through the media conduit 200 but also through the monitoring pipe 100. Since the monitoring pipe 100 is removable, if it is necessary to inspect or detect the corrosion status of the media conduit 200 of the thermal management system, the monitoring pipe 100 can be removed. By inspecting or detecting the corrosion status inside the monitoring pipe 100, the corrosion status of the conduit in the thermal management system can be obtained. This enables inspection or detection of the corrosion status of the conduit in the thermal management system without causing damage to the thermal management system, facilitating inspection and maintenance while simultaneously reducing maintenance costs.

[0053] The battery 300 disclosed in the embodiments of this application can be used in a power consumption device 1000 such as a vehicle, ship, or aircraft, but is not limited to these. By configuring the power supply system of the power consumption device 1000 with the battery 300 disclosed in this application, the difficulty and cost of maintenance of the battery 300 of the power consumption device 1000 can be reduced.

[0054] The embodiments of this application provide a power consumption device 1000 that uses the battery 300 as a power source, and the power consumption device 1000 may be, but is not limited to, a battery car, an electric vehicle, a steamship, a spacecraft, etc. Here, an electric vehicle may include trucks, construction vehicles, passenger cars, etc., and a spacecraft may include airplanes, rockets, spaceplanes, and spacecraft, etc.

[0055] The following describes a thermal management system for battery 300 according to an embodiment of this application, with accompanying drawings.

[0056] As shown in Figures 1 to 4, according to a first embodiment, the embodiment of the present application provides a thermal management system for use in a battery 300, the thermal management system comprising a thermal management system body and a monitoring pipe 100. The thermal management system body includes a medium conduit 200 through which a heat exchange medium flows, the medium conduit 200 having an inlet end 51 and an outlet end 52, and a removable monitoring pipe 100 is provided at at least one of the inlet end 51 and the outlet end 52.

[0057] As the heat exchange medium flows through the thermal management system, it can enter the thermal management system body from the inlet end 51 of the medium conduit 200. As the heat exchange medium flows through the thermal management system body, it can carry away the heat generated by the battery cells or heat the battery cells, and then flow out of the thermal management system body from the outlet end 52 of the medium conduit 200.

[0058] Selectively, the heat exchange medium may be water, or it may be a mixture of water and ethylene glycol.

[0059] The provision of a removable monitoring pipe 100 at at least one of the inlet end 51 and the outlet end 52 may, for example, mean that the removable monitoring pipe 100 is installed at the inlet end 51 of the media conduit 200, or that the removable monitoring pipe 100 is installed at the outlet end 52 of the media conduit 200, or that the removable monitoring pipe 100 is installed at both the inlet end 51 and the outlet end 52 of the media conduit 200.

[0060] In this case, if a removable monitoring pipe 100 is installed at the inlet end 51 of the media conduit 200, the heat exchange medium can flow through the monitoring pipe 100 and into the thermal management system body from the inlet end 51 of the media conduit 200. As the heat exchange medium flows through the thermal management system body, it can carry away the amount of heat generated by the battery cells or heat the battery cells, and then flow out of the thermal management system body from the outlet end 52 of the media conduit 200.

[0061] If a removable monitoring pipe 100 is installed at the outlet end 52 of the media conduit 200, the heat exchange medium can flow into the thermal management system body from the inlet end 51 of the media conduit 200. As the heat exchange medium flows through the thermal management system body, it can carry away the heat generated by the battery cells or heat the battery cells, and then flow out of the thermal management system body from the outlet end 52 of the media conduit 200 and through the monitoring pipe 100.

[0062] When removable monitoring pipes 100 are installed at both the inlet end 51 and the outlet end 52 of the media conduit 200, the heat exchange medium can flow through the monitoring pipe 100 connected to the inlet end 51, and also flow into the thermal management system body from the inlet end 51 of the media conduit 200. In the process of the heat exchange medium flowing through the thermal management system body, the heat exchange medium can carry away the amount of heat generated by the battery cells or heat the battery cells. After that, it can flow out of the thermal management system body from the outlet end 52 of the media conduit 200 and also flow through the monitoring pipe 100 connected to the outlet end 52.

[0063] The removable monitoring pipe 100 is designed so that when the monitoring pipe 100 is removed from the inlet end 51 or outlet end 52 of the media conduit 200, it does not cause damage to the thermal management system, and the monitoring pipe 100 can be reattached to the inlet end 51 or outlet end 52 of the media conduit 200 after it has been removed. The removable connection method between the monitoring pipe 100 and the inlet end 51 or outlet end 52 of the media conduit 200 may include at least one of a swivel connection method, a locking connection method, and a fastener 60 connection method.

[0064] In the above proposed technology, a removable monitoring pipe 100 is provided at least one of the inlet end 51 and outlet end 52 of the media conduit 200 of the thermal management system. As the heat exchange medium circulates and flows through the thermal management system, the heat exchange medium flows not only through the media conduit 200 but also through the monitoring pipe 100. Since the monitoring pipe 100 and the inlet end 51 or outlet end 52 of the media conduit 200 are detachably connected, if it is necessary to inspect or detect the corrosion status of the media conduit 200 of the thermal management system, the monitoring pipe 100 can be removed from the inlet end 51 or outlet end 52 of the media conduit. For example, the corrosion status inside the monitoring pipe 100 can be detected or inspected by the opening of the monitoring pipe 100. By inspecting or detecting the corrosion status inside the monitoring pipe 100, the corrosion status of the conduit in the thermal management system can be obtained. This enables inspection or detection of the corrosion status of the conduit in the thermal management system without causing damage to the thermal management system, facilitating inspection and maintenance while simultaneously reducing maintenance costs.

[0065] In some embodiments, the material of at least a portion of the inner wall of the monitoring pipe 100 is the same as the material of the media conduit 200.

[0066] The material of at least a portion of the inner wall of the monitoring pipe 100 is the same as the material of the media conduit 200, and may include the following situations: For example, the material of a portion of the inner wall of the monitoring pipe 100 is the same as the material of the media conduit 200, and further for example, the material of the entire inner wall of the monitoring pipe 100 is the same as the material of the media conduit 200, and also for example, the material of the entire monitoring pipe 100 is the same as the material of the media conduit 200.

[0067] To understand this, in the case of the same type of heat exchange medium, differences in corrosion resistance may exist depending on the material. As the heat exchange medium flows through the monitoring pipe 100, it comes into contact with at least a portion of the inner wall of the monitoring pipe 100. By making the material of at least a portion of the inner wall of the monitoring pipe 100 the same as the material of the medium conduit 200, the flow environment of the heat exchange medium within the monitoring pipe 100 can be made to resemble or identical to the flow environment of the heat exchange medium within the medium conduit 200, thereby allowing the corrosion status within the monitoring pipe 100 to respond more accurately to the overall corrosion status of the conduit of the thermal management system.

[0068] In some embodiments, referring to Figures 3 and 4, the monitoring pipe 100 is inserted and connected to the media conduit 200.

[0069] For example, the monitoring pipe 100 may be inserted into the inlet end 51 or outlet end 52 of the media conduit 200, or the inlet end 51 or outlet end 52 of the media conduit 200 may be inserted into the monitoring pipe 100.

[0070] By inserting the monitoring pipe 100 into the media conduit 200, and by inserting and removing the monitoring pipe 100, separation and assembly of the monitoring pipe 100 and the media conduit 200 can be easily achieved, making the attachment and detachment of the monitoring pipe 100 easier.

[0071] In some embodiments, referring to Figures 3 and 4, the axial ends of the monitoring pipe 100 have a first pipe opening 101 and a second pipe opening 102, respectively, and the inlet end 51 or outlet end 52 is inserted into the monitoring pipe 100 through the first pipe opening 101. Inserting the inlet end 51 or outlet end 52 of the media conduit 200 into the monitoring pipe 100 facilitates the insertion operation of the monitoring pipe 100 and the media conduit 200.

[0072] In some embodiments, referring to Figures 3 and 4, a first sealing material 30 is provided between the inner circumferential wall of the monitoring pipe 100 and the outer circumferential wall of the media conduit 200, or between the outer circumferential wall of the monitoring pipe 100 and the inner circumferential wall of the media conduit 200.

[0073] For example, when inserting the inlet end 51 or outlet end 52 of the media conduit 200 into the monitoring pipe 100, the first sealing material 30 may be installed between the inner circumferential wall of the monitoring pipe 100 and the outer circumferential wall of the media conduit 200. Alternatively, when inserting the monitoring pipe 100 into the inlet end 51 or outlet end 52 of the media conduit 200, the first sealing material 30 may be provided between the outer circumferential wall of the monitoring pipe and the inner circumferential wall of the media conduit 200.

[0074] Selectively, the first sealing material 30 may be a rubber sealing material or a silica gel sealing material.

[0075] By installing the first sealing material 30 between the monitoring pipe 100 and the media conduit 200, a seal is achieved over the fitting gap between the monitoring pipe 100 and the media conduit 200, preventing leakage at the fitting point between the monitoring pipe 100 and the media conduit 200 as the heat exchange medium flows through the monitoring pipe 100.

[0076] In some embodiments, referring to Figures 3 and 4, the axial ends of the monitoring pipe 100 have a first pipe opening 101 and a second pipe opening 102, respectively, and the inlet end 51 or outlet end 52 is inserted into the monitoring pipe 100 through the first pipe opening 101, and the first sealing material 30 is fixed to the inner circumferential wall of the monitoring pipe 100 and surrounds the inlet end 51 or outlet end 52.

[0077] By fixing the first sealing material 30 to the inner circumferential wall of the monitoring pipe 100, when inserting the inlet end 51 or outlet end 52 of the media conduit 200 into the monitoring pipe 100, the first sealing material 30 is pressed and deformed through the outer circumferential wall of the media conduit 200, thereby easily inserting the inlet end 51 or outlet end 52 of the media conduit 200 into the monitoring pipe 100 and easily sealing both ends.

[0078] In some embodiments, referring to Figures 3 and 4, a first receiving groove 11 is formed in the inner circumferential wall of the monitoring pipe 100, the first receiving groove 11 is formed in an annular shape extending along the circumferential direction of the monitoring pipe 100, and the first sealing material 30 is housed in the first receiving groove 11.

[0079] By providing a receiving groove for accommodating the first sealant 30 on the inner circumferential wall of the monitoring pipe 100, the installation and fixing of the first sealant 30 can be facilitated, and a positional regulating effect can be achieved for the first sealant 30. In this way, during the process of attaching and detaching the monitoring pipe 100, the movement of the first sealant 30 due to frictional force between the media conduit 200 and the first sealant 30 can be avoided, thereby ensuring that the first sealant 30 is held in the set position, and thus the sealing effect of the first sealant 30 can be guaranteed.

[0080] In some embodiments, referring to Figures 3 and 4, the first sealing material 30 includes a first guide portion 31 and a first sealing portion 32 arranged along the axial direction of the monitoring pipe 100, wherein the first guide portion 31 is located on one side of the first sealing portion 32 adjacent to the first pipe opening 101, the inner circumference of the first guide portion 31 defines a first guide passage 311, and in the insertion direction of the inlet end 51 or outlet end 52, the cross-sectional area of ​​the first guide passage 311 gradually decreases, and the first sealing portion 32 abuts against and fits against the outer circumferential wall of the inlet end 51 or outlet end 52.

[0081] By setting the portion of the first seal material 30 closest to the first pipe opening 101 in a flared shape, the first guide passage 311 guides the insertion of the inlet end 51 or outlet end 52 of the media conduit 200 into the first seal material 30. This guide action reduces insertion resistance, further streamlining and simplifying the insertion operation of the media conduit 200 and the monitoring pipe 100. Furthermore, by bringing the first sealing portion 32 of the first seal material 30 into contact with the outer circumferential wall of the media conduit 200, the sealing effect of the first seal material 30 is guaranteed.

[0082] In some embodiments, referring to Figure 4, a first sealing projection 53 is formed on the outer circumferential wall of the inlet end 51 or outlet end 52, the first sealing projection 53 is formed in an annular shape extending along the circumferential direction of the media conduit 200, and the first sealing projection 53 abuts against the first sealing material 30.

[0083] By installing a first sealing projection 53 on the outer circumferential wall of the inlet end 51 or outlet end 52 of the media conduit 200, when the inlet end 51 or outlet end 52 of the media conduit is inserted into the monitoring pipe 100, the first sealing projection 53 presses against the first sealing material 30 located inside the monitoring pipe 100, causing the outer circumferential wall of the inlet end 51 or outlet end 52 of the media conduit to fit more tightly with the first sealing material 30 fixed inside the monitoring pipe 100, thereby further improving the sealing effect.

[0084] In some embodiments, referring to Figure 3, the thermal management system further includes an external conduit, and a monitoring pipe 100 is connected between the external conduit and the medium conduit 200 to form a circulation path, and the monitoring pipe 100 is detachably connected to the external conduit.

[0085] In this case, if a removable monitoring pipe 100 is installed at the inlet end 51 of the media conduit 200, one end of the monitoring pipe 100 is detachably connected to the inlet end 51 of the media conduit 200, the other end of the monitoring pipe 100 is detachably connected to one end of the external conduit, and the other end of the external conduit is connected to the outlet end 52 of the media conduit 200, thereby forming a circulation path for the heat exchange medium.

[0086] When a removable monitoring pipe 100 is installed at the outlet end 52 of the media conduit 200, one end of the monitoring pipe 100 is detachably connected to the outlet end 52 of the media conduit 200, the other end of the monitoring pipe 100 is detachably connected to one end of the external conduit, and the other end of the external conduit is connected to the inlet end 51 of the media conduit 200, thereby forming a circulation path for the heat exchange medium.

[0087] When removable monitoring pipes 100 are installed at both the inlet end 51 and the outlet end 52 of the media conduit 200, one end of the monitoring pipe 100 connected to the inlet end 51 is detachably connected to the inlet end 51 of the media conduit 200, the other end of the monitoring pipe 100 connected to the inlet end 51 is detachably connected to one end of the external conduit, one end of the monitoring pipe 100 connected to the outlet end 52 is detachably connected to the outlet end 52 of the media conduit 200, and the other end of the monitoring pipe 100 connected to the outlet end 52 is detachably connected to the other end of the external conduit, thereby forming a circulation path for the heat exchange medium.

[0088] The removable connection method between the monitoring pipe 100 and the external conduit may include at least one of the following: a swivel connection method, a locking connection method, and a fastener 60 connection method.

[0089] By detachably connecting the monitoring tube 100 to an external conduit located outside the battery 300 of the thermal management system, the entire monitoring tube 100 can be removed from the thermal management system, thereby making it easier to inspect or detect the corrosion condition inside the monitoring tube 100.

[0090] In some embodiments, referring to Figures 5 to 8, the monitoring pipe 100 includes a pipe body 10 and a window cover 20, the monitoring window 12 is formed in the outer wall of the pipe body 10 and penetrates the inner wall of the pipe body 10, the window cover 20 covers the monitoring window 12 and the window cover 20 is removable and / or the window cover 20 is a transparent member.

[0091] The window cover 20 is removable and / or the window cover 20 is a transparent member, including the following situations: for example, the window cover 20 is removable, and further for example, the window cover 20 is a transparent member, and also for example, the window cover 20 is removable and the window cover 20 is a transparent member.

[0092] Here, if the window cover 20 is removable, it is necessary to inspect or detect the corrosion status inside the monitoring pipe 100. The monitoring pipe 100 may be removed from the inlet end 51 or outlet end 52 of the media conduit 200, and the window cover 20 may be removed from the monitoring window 12 of the monitoring pipe 100. In this way, the corrosion status inside the monitoring pipe 100 can be inspected or detected by the monitoring window 12. The corrosion status inside the monitoring pipe 100 can also be inspected or detected by the pipe opening of the pipe body 10. In this way, the routes for inspecting or detecting the corrosion status inside the monitoring pipe 100 can be increased, making the inspection or detection of the corrosion status of the monitoring pipe 100 more accurate and comprehensive, and also making the inspection or detection of the corrosion status inside the monitoring pipe 100 more convenient and flexible.

[0093] If the window cover 20 is a transparent material, it is necessary to inspect or detect the corrosion status inside the monitoring pipe 100. The monitoring pipe 100 can be removed from the inlet end 51 or outlet end 52 of the media conduit 200, and the corrosion status inside the monitoring pipe 100 can be observed using the window cover 20. The corrosion status inside the monitoring pipe 100 can also be inspected or detected using the pipe opening of the pipe body 10. In this way, the routes for inspecting or detecting the corrosion status inside the monitoring pipe 100 can be increased, making the inspection or detection of the corrosion status of the monitoring pipe 100 more accurate and comprehensive, and also making the inspection or detection of the corrosion status inside the monitoring pipe 100 more convenient and flexible.

[0094] If the window cover 20 is removable and transparent, it is necessary to inspect or detect the corrosion status inside the monitoring pipe 100. The monitoring pipe 100 can be removed from the inlet end 51 or outlet end 52 of the media conduit 200, and the window cover 20 can be removed from the monitoring window 12 of the monitoring pipe 100 as needed, or it may not be necessary to remove it. When the window cover 20 is removed from the monitoring window 12 of the monitoring pipe 100, the corrosion status inside the monitoring pipe 100 can be inspected or detected by the monitoring window 12. When the window cover 20 is not removed, the corrosion status inside the monitoring pipe 100 can be observed by the window cover 20. The corrosion status inside the monitoring pipe 100 can also be inspected or detected by the pipe opening of the pipe body 10. In this way, the routes for inspecting or detecting the corrosion status inside the monitoring pipe 100 can be increased, making the inspection or detection of the corrosion status of the monitoring pipe 100 more accurate and comprehensive, and making the inspection or detection of the corrosion status inside the monitoring pipe 100 more convenient and flexible.

[0095] By installing a monitoring window 12 on the surrounding wall of the monitoring pipe 100, the number of routes for inspecting or detecting the monitoring pipe 100 can be increased, making the inspection or detection of the corrosion status of the monitoring pipe 100 more convenient, accurate, and comprehensive.

[0096] Selectively, the monitoring window 12 may be one or multiple, and each monitoring window 12 is covered with a window cover 20. When there are multiple monitoring windows 12, they may be arranged at intervals along the axial and / or circumferential direction of the pipe 10, and when there are multiple monitoring windows 12, the number of inspection or detection paths for the monitoring pipe 100 can be increased, making the inspection more convenient, flexible, more accurate, and more comprehensive.

[0097] In some embodiments, the material of the pipe body 10 is the same as the material of the media conduit 200, and / or the material of the window cover 20 is the same as the material of the media conduit 200.

[0098] For example, the material of the pipe body 10 may be the same as the material of the media conduit 200, thereby making the flow environment inside the monitoring pipe 100 of the heat exchange medium closer to or the same as the flow environment inside the media conduit 200 of the heat exchange medium, thereby allowing the corrosion status inside the monitoring pipe 100 to respond more accurately to the overall corrosion status of the conduit of the thermal management system. It is necessary to inspect or detect the corrosion status inside the monitoring pipe 100, and this can be done by inspecting the corrosion status inside the pipe body 10 through the monitoring window 12 or the opening of the pipe body 10.

[0099] Furthermore, for example, the material of the window cover 20 may be the same as the material of the media conduit 200, thereby making the flow environment inside the monitoring pipe 100 of the heat exchange medium closer to or identical to the flow environment inside the media conduit 200 of the heat exchange medium, thereby allowing the corrosion status inside the monitoring pipe 100 to respond more accurately to the overall corrosion status of the conduit of the thermal management system. If it is necessary to inspect or detect the corrosion status inside the monitoring pipe 100, the window cover 20 can be removed from the monitoring window 12, and the corrosion status of the inner wall of the window cover 20 can be inspected or detected.

[0100] For example, the material of the pipe body 10 may be the same as the material of the media conduit 200, and the material of the window cover 20 may also be the same as the material of the media conduit 200. This makes it possible to bring the flow environment inside the monitoring pipe 100 of the heat exchange medium closer to or the same as the flow environment inside the media conduit 200 of the heat exchange medium, thereby allowing the corrosion status inside the monitoring pipe 100 to respond more accurately to the overall corrosion status of the conduit of the thermal management system. It is necessary to inspect or detect the corrosion status inside the monitoring pipe 100, and this can be done by inspecting the corrosion status inside the pipe body 10 through the monitoring window 12 or the opening of the pipe body 10, and the corrosion status of the inner wall of the window cover 20 can also be inspected or detected.

[0101] In this way, the flow environment inside the monitoring pipe 100 of the heat exchange medium can be made to resemble or identical to the flow environment inside the medium pipeline 200 of the heat exchange medium, thereby allowing the corrosion status inside the monitoring pipe 100 to respond more accurately to the overall corrosion status of the pipeline in the thermal management system.

[0102] In some embodiments, as shown in Figure 5, the inner wall surface of the window cover 20 is installed on the same plane as the inner wall surface of the pipe 10.

[0103] The inner wall surface of the window cover 20 refers to the wall surface of the window cover 20 facing the flow path inside the monitoring pipe 100, and the inner wall surface of the window cover 20 can come into contact with the heat exchange medium. The inner wall surface of the pipe body 10 refers to the wall surface of the pipe body 10 facing the flow path inside the monitoring pipe 100, and the inner wall surface of the pipe body 10 can come into contact with the heat exchange medium.

[0104] The inner wall surface of the window cover 20 being installed on the same plane as the inner wall surface of the pipe 10 may include the inner wall surface of the window cover 20 and the inner wall surface of the pipe 10 being installed on the same plane, or it may include allowing situations where the inner wall surface of the window cover 20 and the inner wall surface of the pipe 10 are not on the same plane due to manufacturing and assembly errors.

[0105] In this way, the flow environment inside the monitoring pipe 100 of the heat exchange medium can be made to resemble or identical to the flow environment inside the medium pipeline 200 of the heat exchange medium, thereby allowing the corrosion status inside the monitoring pipe 100 to respond more accurately to the overall corrosion status of the pipeline in the thermal management system.

[0106] In some embodiments, as shown in Figure 5, the outer wall surface of the window cover 20 is installed in the same plane as the outer wall surface of the pipe 10.

[0107] The exterior wall surface of the window cover 20 refers to the wall surface on which the window cover 20 is exposed to the outside, and the exterior wall surface of the pipe 10 refers to the wall surface on which the pipe 10 is exposed to the outside.

[0108] The fact that the outer surface of the window cover 20 is installed on the same plane as the outer surface of the pipe 10 may include the fact that the outer surface of the window cover 20 and the outer surface of the pipe 10 are installed on the same plane, or it may include the fact that, due to manufacturing and assembly errors, the outer surface of the window cover 20 and the outer surface of the pipe 10 are not on the same plane.

[0109] In this way, the window cover 20 can avoid protruding from the pipe body 10 and occupying extra space, thereby making the structure more compact and preventing the formation of a large step between the window cover 20 and the pipe body 10 that could injure workers or other components.

[0110] In some embodiments, as shown in Figure 5, a third sealing material 50 is provided between the window cover 20 and the pipe body 10.

[0111] Selectively, the third sealing material 50 may be a rubber sealing material or a silica gel sealing material.

[0112] By installing a third sealing material 50 between the window cover 20 and the pipe body 10, the fitting gap between the window cover 20 and the pipe body 10 can be sealed, and leakage of the heat exchange medium from the fitting area between the window cover 20 and the pipe body 10 can be prevented as the heat exchange medium flows through the monitoring pipe 100.

[0113] In some embodiments, as shown in Figures 5 to 8, the window cover 20 and the pipe 10 are connected by fasteners 60.

[0114] Selectively, the fastener 60 may be a threaded fastener 60, for example, the fastener 60 may be a screw or a bolt.

[0115] The window cover 20 is attached and secured to the 12 monitoring windows of the pipe body 10 using the fasteners 60, making it easy to attach and detach the window cover 20 and ensuring the strength of the connection between the window cover 20 and the pipe body 10.

[0116] In some embodiments, referring to Figures 5 to 8, the monitoring window 12 is formed in a stepped hole, and the outer peripheral wall of the window cover 20 is formed in a stepped shape to fit the stepped hole.

[0117] The outer perimeter wall of the window cover 20 refers to the wall where the window cover 20 and the inner perimeter wall of the monitoring window 12 fit together.

[0118] By installing the monitoring window 12 in a stepped hole and setting the outer periphery wall of the window cover 20 in a stepped shape that fits the stepped hole, the fitting area between the window cover 20 and the pipe body 10 can be increased, and at the same time, the installation and fixing of the window cover 20 can be made easier.

[0119] In some embodiments, referring to Figures 5 to 8, the observation window 12 includes a first hole 121 and a second hole 122 arranged along the thickness direction of the pipe body 10, wherein the cross-sectional area of ​​the first hole 121 is larger than that of the second hole 122 and the first hole 121 is located radially outward of the second hole 122, and a stepped surface 13 is formed between the first hole 121 and the second hole 122. The window cover 20 includes a cover plate 21 and a boss 22, the boss 22 is provided on the inside of the cover plate 21, the cover plate 21 is housed in the first hole 121 and the cover plate 21 abuts against the stepped surface 13, and the boss 22 is housed in the second hole 122.

[0120] The inside of the cover plate 21 refers to the side of the cover plate 21 that faces the flow path inside the pipe 10.

[0121] If the window cover 20 includes the cover plate 21 and boss 22 described above, the inner wall surface of the window cover 20 refers to the wall surface of the boss 22 facing the flow path inside the monitoring pipe 100.

[0122] By setting the monitoring window 12 as a stepped hole that is larger on the outside and smaller on the inside, the monitoring window 12 makes it easier to inspect or detect the corrosion status inside the pipe body 10. Furthermore, by setting the window cover 20 to have a structure with a boss 22, the portion of the cover plate 21 located on the outer circumference side of the boss 22 supports and contacts the stepped surface 13 inside the monitoring window 12, improving the mounting stability of the window cover 20. At the same time, the stepped surface 13 can support the cover plate 21 during the process of attaching and detaching the window cover 20, thus facilitating the attachment and detachment of the window cover 20.

[0123] In some embodiments, as shown in Figure 5, a third sealing material 50 is provided between the cover plate 21 and the stepped surface 13.

[0124] Selectively, the third sealing material 50 may be fixed to the stepped surface 13.

[0125] By installing a third sealing material 50 between the cover plate 21 of the window cover 20 and the stepped surface 13 of the pipe body 10, the fitting gap between the window cover 20 and the pipe body 10 can be sealed, preventing the heat exchange medium from leaking from the fitting area between the window cover 20 and the pipe body 10 as the heat exchange medium flows through the monitoring pipe 100. Furthermore, by installing the third sealing material 50 between the cover plate 21 and the stepped surface 13, the stepped surface 13 can provide support for the third sealing material 50, facilitating the installation and fixing of the third sealing material 50.

[0126] In some embodiments, referring to Figures 5 to 7, a third receiving groove 15 is formed in the stepped surface 13, the third receiving groove 15 is formed in an annular shape extending along the circumferential direction of the first hole 121, and the third sealing material 50 is housed in the third receiving groove 15.

[0127] By installing a third receiving groove 15 for accommodating the third sealing material 50 in the stepped surface 13, the installation and fixing of the third sealing material 50 is facilitated, and the third receiving groove 15 can perform a positional restricting effect on the third sealing material 50, preventing the third sealing material 50 from moving and affecting the sealing effect, thereby ensuring the sealing effect of the third sealing material 50.

[0128] In some embodiments, as shown in Figures 5 to 7, a first connection hole 211 is formed in the cover plate 21, a second connection hole 16 is formed in the stepped surface 13, and fasteners 60 are drilled in the first connection hole 211 and the second connection hole 16 to fix the window cover 20 to the pipe body 10.

[0129] The fastener 60 is drilled into the cover plate 21 and penetrates the pipe body 10 via the stepped surface 13, allowing the cover plate 21 to be securely attached to the observation window 12 of the pipe body 10. Furthermore, since the fastener 60 penetrates the pipe body 10 from the stepped surface 13, the fastener 60 is easily installed.

[0130] In some embodiments, referring to Figure 5, the second connection hole 16 is a blind hole.

[0131] The second connection hole 16 is a blind hole, meaning that the second connection hole 16 does not penetrate the inner wall surface of the pipe body 10.

[0132] By setting the second connection hole 16 on the stepped surface 13 of the installed pipe body 10 as a blind hole, and by having the second connection hole 16 penetrate the inner circumferential wall of the pipe body 10, leakage of the heat exchange medium flowing inside the monitoring pipe 100 from the fitting point between the second connection hole 16 and the fastener 60 can be prevented, thereby improving the assembly seal between the cover plate 21 and the pipe body 10.

[0133] In a second aspect, referring to Figure 1, the embodiment of the present application further provides a battery 300, which includes at least one battery cell and the thermal management system, the thermal management system being used to regulate the temperature of the battery cell.

[0134] By adopting the above-mentioned thermal management system, it becomes possible to inspect or detect the corrosion status of the thermal management system's piping without causing damage to the thermal management system itself, thereby facilitating inspection and maintenance while simultaneously reducing maintenance costs.

[0135] In some embodiments, referring to Figure 1, the battery 300 includes a housing 301, the battery cells and the thermal management system body are both located inside the housing 301, the inlet end 51 and outlet end 52 of the media conduit 200 are both located outside the housing 301, and the monitoring pipe 100 is located outside the housing 301.

[0136] The monitoring tube 100 is installed outside the housing 301 of the battery 300. When it is necessary to remove the monitoring tube 100 from the battery 300 to inspect or detect corrosion, it is not necessary to remove the housing 301 of the battery 300, making it easier to inspect or detect the corrosion status of the piping in the thermal management system.

[0137] According to a third aspect, the embodiment of the present application further provides a power consumption device 1000 which includes the battery 300, the battery 300 being used to provide electrical energy to the power consumption device 1000.

[0138] By adopting the above-mentioned thermal management system, it becomes possible to inspect or detect the corrosion status of the thermal management system's piping without causing damage to the thermal management system itself, thereby facilitating inspection and maintenance while simultaneously reducing maintenance costs.

[0139] Selectively, as shown in Figure 9, when the battery 300 is used in a vehicle, the battery 300 may be installed at the bottom, front, or rear of the vehicle. The battery 300 may be used to power the vehicle; for example, the battery 300 may be used as the operating power source for the vehicle. The vehicle may further include a controller and a motor, the controller being used to control the battery 300 to power the motor and to meet the operating power consumption requirements for, for example, starting the vehicle, navigation, and driving.

[0140] The following describes some embodiments of the present application, including a thermal management system and a battery 300 having the same, with reference to Figures 1 to 8.

[0141] In this embodiment, the battery 300 includes a housing 301, at least one battery cell, and a thermal management system, the thermal management system includes a thermal management system body, a monitoring pipe 100, and an external conduit, both of which are located inside the housing 301, the inlet end 51 and outlet end 52 of the media conduit 200 are located outside the housing 301, a removable monitoring pipe 100 is installed at least one of the inlet end 51 and outlet end 52 of the media conduit 200, the monitoring pipe 100 is located outside the housing 301, one end of the monitoring pipe 100 is inserted into the inlet end 51 or the outlet end 52, and the other end of the monitoring pipe 100 is inserted into the external conduit.

[0142] The monitoring pipe 100 includes a pipe body 10, a window cover 20, a first sealant 30, a second sealant 40, a third sealant 50, and fasteners 60.
