Background Technology

[0002] In thermal management systems, sensors are used to measure the temperature or pressure of fluid within a flow channel. Related technologies typically involve sensors comprising a housing, a sleeve, and a temperature-sensing unit. Part of the temperature-sensing unit is located within the sleeve, which is fixedly connected to the housing. The flow channel plate includes a mounting cavity through which the sensor passes into the flow channel. The sensor and flow channel plate are fixedly connected by a snap ring. This requires a connection structure on the sensor and flow channel plate that mates with the snap ring, and the installation of the snap ring necessitates installation space, which is detrimental to the miniaturization of the integrated module. Alternatively, a flange can be installed on the sensor, and the flange is connected to the flow channel plate by screws. This structure is relatively complex, and the installation of the flange and flow channel plate requires space, also hindering the miniaturization of the integrated module. Summary of the Invention

[0003] Therefore, it is necessary to provide a relatively simple integrated module and a method for manufacturing the integrated module to address the above problems.

[0004] The technical solution of this application provides an integrated module, including a flow channel assembly and a sensing assembly. The flow channel assembly includes a flow channel portion and a sleeve. The flow channel portion includes a flow channel, and a portion of the sleeve is embedded in the flow channel portion. The sleeve is fixedly connected to the flow channel portion, and one end of the sleeve is located inside the flow channel. The sensing assembly includes a temperature sensing unit and a housing. A portion of the temperature sensing unit is located inside the housing, and the temperature sensing unit is fixedly connected to or limited by the housing. The temperature sensing unit includes a temperature sensing element, which is located inside the sleeve. The housing is welded and fixed to the flow channel portion.

[0005] The integrated module provided by this application has a sleeve embedded in the flow channel, a part of the temperature sensing unit located in the sleeve, a part of the temperature sensing element fixedly connected or limited to the outer shell, and the outer shell welded to the flow channel. The structure is relatively simple, and the connection structure between the sleeve and the outer shell is eliminated, which requires relatively little installation space and is conducive to the miniaturization of the integrated module.

[0006] The manufacturing method of the integrated module provided by this application includes the following steps:

[0007] Assemble the flow channel assembly: Place the sleeve inside the injection molding film and injection mold at least part of the flow channel assembly;

[0009] The temperature sensing element is placed inside the sleeve, and the outer shell is welded and fixed to the flow channel assembly.

[0010] The manufacturing method of the integrated module provided by this application involves first fixing the sleeve to the flow channel, assembling the sensing component, placing its temperature sensing element inside the sleeve, and welding the outer shell to the flow channel.

The terms “front,” “rear,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the accompanying drawings; the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] It should be understood that although various information may be described using terms such as "first," "second," "third," and "fourth" in this application, this information should not be limited to these descriptions. These terms are only used to distinguish information of the same type from one another. "Multiple" means two or more. Where there is no conflict, the features of the various technical solutions in this application can complement or replace each other.

[0024] The integrated module of this application can be implemented in various ways. At least one of these implementations can be applied to a vehicle thermal management system, and at least one of these implementations can be applied to other thermal management systems such as a residential thermal management system or a commercial thermal management system. The following description uses an integrated module for vehicles as an example, in conjunction with the accompanying drawings.

[0025] Combination Figure 1-9The integrated module of this application includes a flow channel assembly 10 and a sensing assembly 20. At least a portion of the sensing assembly 20 is located within the flow channel 110 of the flow channel assembly 10, and is used to measure the temperature and / or pressure of the fluid within the flow channel 110. The flow channel assembly 10 includes a flow channel portion 11 and a sleeve 12. The flow channel portion 11 includes the flow channel 110, and a portion of the sleeve 12 is embedded in the flow channel portion 11, with one end of the sleeve 12 located within the flow channel 110. The sleeve 12 is fixedly connected to the flow channel portion 11, and the fixed connection includes welding, bonding, threaded connection, or the sleeve 12 being injection molded as an insert into the flow channel portion 11 as an integral structure. The sensing assembly 20 includes a temperature sensing unit 22 and a housing 21. A portion of the temperature sensing unit 22 is located within the housing 21, and the temperature sensing unit 22 is fixedly connected to or limited by the housing 21. The temperature sensing unit 22 includes a temperature sensing element 221, which is located within the sleeve 12. The housing 21 is welded and fixed to the flow channel portion 11. In this application, the temperature sensing element 221 is a thermistor, thermocouple, or resistance temperature detector (RTD). The temperature sensing element 221 can convert the temperature of the fluid within the flow channel 110 into an electrical signal. In related technologies, the sensor includes a housing, a sleeve, and a temperature sensing unit. Part of the temperature sensing unit is located within the sleeve, which is limited or fixedly connected to the housing. The flow channel plate includes a mounting cavity that communicates with the flow channel. The sensor passes through the mounting cavity into the flow channel, and the sensor and flow channel are fixedly connected by a snap ring. This requires a connection structure on the sensor and flow channel plate that mates with the snap ring, resulting in a relatively complex structure. Furthermore, mounting the snap ring requires installation space, which is detrimental to the miniaturization of the integrated module. Alternatively, a flange can be installed on the sensor, and the flange is connected to the flow channel plate by screws. This flange installation is complex, relatively expensive, and requires space for installation, also hindering the miniaturization of the integrated module. In this application, the sleeve 12 is embedded in the flow channel 11, part of the temperature sensing unit 22 is located in the sleeve 12, part of the temperature sensing element 221 is fixedly connected or limited to the outer shell 21, and the outer shell 21 is welded and fixed to the flow channel 11. The structure is relatively simple, the connection structure between the sleeve 12 and the outer shell 21 is eliminated, and there is no need for a complex assembly structure between the outer shell 21 and the flow channel 11. Its cost is relatively reduced, the required installation space is relatively small, which is conducive to the miniaturization of the integrated module and the automation of manufacturing.

[0026] Combination Figure 1-8The following describes a specific embodiment of the present application. The integrated module includes a flow channel assembly 10 and a sensing assembly 20. The flow channel assembly 10 includes a flow channel 110, and at least a portion of the sensing assembly 20 is located in the flow channel 110 for detecting the temperature within the flow channel 110. The flow channel 11 includes a first portion 111 and a second portion 112, which are fixedly connected. In this embodiment, the first portion 111 and the second portion 112 are welded together. The first portion 111 and the second portion 112 cooperate to form a flow channel 110, that is, at least one of the first portion 111 and the second portion 112 has a cavity 101. It can be understood that if the first portion 111 has a cavity 101 and the second portion 112 has a cavity 101, then the cavity 101 of the first portion 111 and the cavity 101 of the second portion 112 cooperate to form at least a portion of the flow channel 110, or the cavity 101 of the first portion 111 and the planar portion of the second portion 112 cooperate to form at least a portion of the flow channel 110, or the planar portion of the first portion 111 and the cavity 101 of the second portion 112 cooperate to form at least a portion of the flow channel 110. It should be noted that the aforementioned flow channel 110 is not only a channel for fluid to pass through, but can also be a liquid storage cavity for storing liquid fluid, that is, a channel for fluid to pass through or a cavity for storing liquid fluid formed by the cooperation of the first part 111 and the second part 112. The flow channel assembly 10 includes a sleeve 12, which is embedded in the flow channel part 11 and fixedly connected to the flow channel part 11. In this embodiment, the sleeve 12 is made of metal, which has better heat transfer performance. However, in other embodiments, rigid plastic or the like can also be used. The sleeve 12 is injection molded with the first part 111 to form an integral structure. In related technologies, the sleeve and the sensor housing are first fixedly connected. The sleeve passes through the mounting hole of the flow channel plate, and the sensor is fixedly connected to the flow channel plate. In order to prevent fluid leakage, a sealing ring is set between the sensor and the flow channel plate. The sleeve of the sensor is an injection molded part, and the outer wall of the sleeve forms a parting line. After contacting the sealing ring, there is a risk of leakage. In this application, the sleeve 12 and the flow channel part 11 are injection molded as one piece, which can reduce the risk of leakage.

[0027] The sleeve 12 is a tubular structure with one end open, facing the sensing component 20. The sleeve 12 includes a main body 121 and a flange 122. Along the axial direction of the sleeve 12, the flange 122 is closer to the outer shell 21 than the main body 121. Along the radial direction of the sleeve 12, the flange 122 extends away from the main body 121. Part of the main body 121 is located in the flow channel 110. The flow channel 11 includes an annular boss 113, which surrounds the flange 122 and is fixedly connected to the flange 122. An annular boss 113 is located in the first portion 111, and extends along the end of the first portion 111 toward the housing 21 of the sensing assembly 20. The flange 122 of the sleeve 12 is fixed to the annular boss 113. When the sleeve 12 is injection molded into an integral structure with the first portion 111 in the form of an insert, the setting of the annular boss 113 increases the contact area between the sleeve 12 and the first portion 111, which is more conducive to the connection between the sleeve 12 and the first portion 111. Figure 7 As shown, the first portion 111 includes a protrusion 1111 that extends into the flow channel 110 and encloses a portion of the main body 121. This structure increases the contact area between the sleeve 12 and the first portion 111, making the connection between the sleeve 12 and the first portion 111 more convenient. The sleeve 12 is injection molded with the first portion 111 as an insert, forming an integral structure, which is relatively simple. Of course, in other embodiments, the flow channel 11 includes a mounting hole and an insertion mounting hole for the sleeve 12, and the sleeve 12 is limited or fixedly connected to the flow channel 11. That is, the sleeve 12 and the flow channel 11 are provided with a limiting structure, and the sleeve 12 is limited and fixed to the flow channel 11, or the sleeve 12 and the flow channel 11 can be fixed by adhesive bonding. The sleeve 12 is first fixed to the flow channel section 11, and then the sensing component 20 is assembled to the flow channel section 11. The housing 21 of the sensing component 20 is welded and fixed to the flow channel section 11. The required installation space is relatively small, which is conducive to the miniaturization of the integrated module and the automation of manufacturing.

[0028] In some embodiments, the flow channel assembly 10 includes a seal 13 located between the sleeve 12 and the flow channel portion 11. The seal 13 is integrally formed with at least a portion of the sleeve 12 and the flow channel portion 11 by injection molding as an insert. For integrated modules with relatively high sealing requirements, the seal 13 is provided between the sleeve 12 and the flow channel portion 11. The seal 13 is integrally formed with the sleeve 12 and the first portion 111 by injection molding as an insert. The seal 13 not only provides a better sealing effect but also improves the strength of the flow channel assembly 10.

[0029] In this embodiment, the outer shell 21 of the sensing component 20 is welded and fixed to the flow channel portion 11. Specifically, the sensing component 20 includes a temperature sensing unit 22 and an outer shell 21. The outer shell 21 has a hollow structure with openings at both ends. Part of the temperature sensing unit 22 is located inside the outer shell 21 and is welded and fixed to the outer shell 21. The temperature sensing unit 22 includes a conductive element 222 and a temperature sensing element 221. One end of the conductive element 222 is fixed to and electrically connected to the temperature sensing element 221. The temperature sensing element 221 is located inside the sleeve 12. The sensing component 20 also includes a connecting plug 23 and a fixing member 24. One end of the connecting plug 23... One end of the connector 23 contacts and is electrically connected to the other end of the conductive element 222. Specifically, part of the connector 23 contacts and is fixed in the fixing member 24, i.e., the fixing member 24 is used to fix the connector 23 and the conductive element 222. In this embodiment, the connector 23 and the conductive element 222 are integrally formed with the fixing member 24 by injection molding as an insert. Of course, in other embodiments, the connector 23 and the conductive element 222 can also be fixed in the fixing member 24 by snap-fit ​​or other limiting and fixing methods. The fixing member 24 is made of insulating material. The outer shell 21 protects the temperature sensing unit 22 and the connector 23. The fixing member 24 is located inside the outer shell 21 and is fixedly connected or limitedly connected to the outer shell 21. In this embodiment, the fixing member 24 is integrally formed with the outer shell 21 by injection molding as an insert. That is, the connector 23 and the conductive element 222 are first injection molded into an integral structure, and then the outer shell 21 is formed by secondary injection molding. The housing 21 of the sensing component 20 is formed by injection molding, which fixes the connector 23 and the conductive element 222. The structure is relatively simple and the connection is more secure and safer.

[0030] The flow channel section 11 includes a limiting part 114 located in the first section 111. The outer shell 21 includes a mating part 211 located at the end of the outer shell 21 near the first section 111. During assembly, the limiting part 114 and the mating part 211 engage to limit the position of the assembled outer shell 21. Specifically, as shown... Figure 5As shown, the limiting part 114 is an annular protrusion 1141, which extends from the end of the first portion 111 toward the outer shell 21. The mating part 211 is a stepped structure formed on the outer shell 21, that is, the stepped structure forms the end of the outer shell 21. The mating part 211 includes a bottom wall part 2111 and a side wall part 2112. The bottom wall part 2111 is disposed relative to the annular protrusion 1141. The limiting part 114 is located inside the mating part 211. Along the radial direction of the sleeve 12, the limiting part 114 is located inside the side wall part 2112. The limiting part 114 abuts against the bottom wall part 2111. The limiting part 114 is welded and fixed to the bottom wall part 2111. The limiting part 114 is in contact or clearance fit with the side wall part 2112. In this embodiment, the limiting part 114 and the side wall part 2112 have a small clearance fit, which is beneficial for absorbing manufacturing tolerances and is more conducive to assembly. The limiting part 114 is located inside the side wall part 2112. During welding, the overflow material is covered by the outer shell 21, so it does not affect the appearance or the smoothness of the assembly surface. Figure 9 As shown, in some other embodiments, the limiting part 114 is a groove 1142, which is recessed inward along the end face of the flow channel part 11. At least part of the mating part 211 is located in the groove 1142, defining the assembly position of the outer shell 21. The limiting part 114 and the mating part 211 are welded and fixed. The welding method can be laser welding, friction welding, etc.

[0031] In the above embodiments, the flow channel 11 includes a first portion 111 and a second portion 112. The first portion 111 and the second portion 112 cooperate to form part of the flow channel 110. The above structure is applicable to situations where the flow channel 110 is relatively complex. In other embodiments, the flow channel structure of the flow channel is relatively simple, and the flow channel can also be an integral structure.

[0032] This application also discloses a method for manufacturing an integrated module, including the following steps:

[0033] Assemble the flow channel assembly 10: Place the sleeve 12 inside the injection molding film and injection mold at least part of the flow channel assembly 10; the sleeve 12 is made of metal material and has a hollow structure with one end open.

[0034] Assemble the sensing component 20; assemble the temperature sensing element 221, the conductive element 222, and the housing 21;

[0035] The temperature sensing element 221 of the sensing component 20 is placed inside the sleeve 12, and the outer shell 21 is welded and fixed to the flow channel component 10.

[0036] In the above-described steps of assembling the flow channel assembly 10, the flow channel assembly 10 includes a first portion 111 and a second portion 112. The specific manufacturing process is as follows: the processed sleeve 12 is placed in the injection mold, the first portion 111 of the flow channel assembly 10 is formed by injection molding, the second portion 112 of the flow channel assembly 10 is formed by injection molding, and the first portion 111 and the second portion 112 with the sleeve 12 are welded and fixed to form at least a portion of the flow channel 110. The portion of the sleeve 12 is located inside the flow channel 110 and is used to detect the temperature of the fluid inside the flow channel 110. To make the connection between the sleeve 12 and the first part 111 more secure, the sleeve 12 is processed to form a main body 121 and a flange 122. An annular boss 113 and an annular protrusion 1141 of the flow channel part 11 are injection molded in the first part 111. The annular boss 113 surrounds and fixes the flange 122, and the annular protrusion 1141 limits the housing 21 of the sensing component 20 and is welded and fixed to the housing 21.

[0037] In the above-described steps of assembling the sensing component 20, the sensing component 20 further includes a connecting plug 23. The connecting plug 23 and the conductive element 222 are partially placed in the injection mold and injection molded to form a first component, so that the connecting plug 23 and the conductive element 222 are fixed and electrically connected. The first component is placed in the injection mold and injection molded to form part of the sensing component 20, that is, through secondary injection molding, the outer shell 21 of the sensing component 20 is formed to protect the temperature sensing unit 22 and the connecting plug 23.

[0038] Before inserting the temperature sensing element 221 into the sleeve 12, thermally conductive material is filled into the sleeve 12, and then the temperature sensing element 221 is placed inside the thermally conductive material. In this embodiment, thermally conductive silicone grease is used as the thermally conductive material, which is beneficial for heat transfer.

[0039] The aforementioned manufacturing method for the integrated module changes the sensor assembly method in related technologies. In related technologies, the sensor housing and sleeve are first fixed or limited, and then the sensor sleeve is inserted into the mounting hole of the flow channel plate. The sensor and flow channel plate are fixedly connected by a snap ring. Assembling the snap ring requires installation space, or a flange is installed on the sensor, and the flange is connected to the flow channel plate by screws. The installation of the snap ring and the flow channel plate, and the installation of the flange and the flow channel plate, require space, which is not conducive to the miniaturization of the integrated module and to manufacturing automation. In the manufacturing method of the integrated module of this application, the sleeve 12 is first fixed together with the flow channel part 11, and then the remaining sensing components are assembled. The temperature sensing element 221 is placed inside the sleeve 12, and the housing 21 is welded and fixed to the flow channel part 11. This eliminates the assembly process of the sleeve and housing, making the manufacturing process relatively simple and conducive to manufacturing automation.

[0040] The above examples illustrate the principles and implementation methods of the present invention. These embodiments are merely illustrative and intended to aid in understanding the method and core concepts of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the present invention.
