Description

Technical Field

[0001] This application relates to the field of thermal management technology, and more particularly to an integrated component for a vehicle thermal management system. Background Technology

[0002] The integrated component includes a flow channel cavity through which a working medium flows. Under certain operating conditions, the working medium may generate bubbles, and the presence of these bubbles can affect the heat exchange efficiency. Currently, the exhaust efficiency of integrated components is relatively low. Utility Model Content

[0003] The purpose of this application is to propose an integrated component that improves the exhaust efficiency of the integrated component.

[0004] To achieve the above objectives, one technical solution of this application is as follows: An integrated component, comprising a flow channel plate assembly, the flow channel plate assembly comprising a flow channel portion and a gas collection portion, the flow channel portion having a flow channel cavity, the gas collection portion having a gas collection cavity, the gas collection cavity comprising a first opening and a second opening, the first opening communicating with the flow channel cavity, the second opening being formed on the outer wall portion of the flow channel plate assembly, the flow channel plate assembly comprising a liquid replenishment portion, the liquid replenishment portion comprising a liquid replenishment cavity communicating with the flow channel cavity, the liquid replenishment cavity comprising a liquid replenishment port, the liquid replenishment port being formed on the outer wall portion of the flow channel plate assembly, the liquid replenishment port being spaced apart from the second opening.

[0005] The technical solution of this application includes a gas collection chamber comprising a first opening and a second opening. The first opening communicates with the flow channel cavity, and the second opening is formed on the outer wall of the flow channel plate assembly. The flow channel plate assembly includes a liquid replenishment section, which includes a liquid replenishment chamber communicating with the flow channel cavity. The liquid replenishment chamber includes a liquid replenishment port, which is formed on the outer wall of the flow channel plate assembly. The liquid replenishment port and the second opening are spaced apart. This provides a foundation for setting other structures (such as degassing structures) between the liquid replenishment port and the second opening. Furthermore, the bubbles discharged from the second opening can be fully degassed, and the fully degassed working medium then enters the flow channel cavity through the liquid replenishment port. Compared with technical solutions where the liquid replenishment port and the second opening are adjacent, this approach reduces the likelihood of bubbles discharged from the second opening not being fully degassed before entering the liquid replenishment port. Thus, this method helps improve the exhaust efficiency of the integrated assembly. Attached Figure Description

[0027] The embodiments of this application will be further described below with reference to the accompanying drawings:

[0028] The integrated components of the technical solution 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 home thermal management system or a commercial thermal management system. The fluid in the fluid management device can be coolant, oil, or other media. The following description uses a fluid management device applied to a vehicle thermal management system as an example, in conjunction with the accompanying drawings.

[0029] Please see Figures 1 to 9As shown. One embodiment of this application provides an integrated component 100, which can be used in a vehicle thermal management system. The integrated component 100 includes a flow channel plate assembly 11, which includes a flow channel portion 111 and a flow channel cavity 112. The flow channel portion 111 forms or is a part of the flow channel cavity 112. The flow channel plate assembly 11 includes at least one mounting portion 121, and the mounting cavity 1211 of the mounting portion 121 communicates with the flow channel cavity 112. The integrated component 100 also includes a fluid management device 114, which is fixedly connected or limitedly connected to the flow channel plate assembly 11. The fluid management device 114 includes at least one of an electric valve 1142 and an electric pump 1141. The flow channel plate assembly 11 also includes a mating portion, and the mounting portion 121 is sealed to the mating portion, thereby enabling the fluid management device 114 to communicate with the flow channel cavity 112. Specifically, when the fluid management device 114 includes an electric valve 1142, the electric valve 1142 can control the flow rate or on / off state of the coolant in the flow channel cavity 112. When the fluid management device 114 includes an electric pump 1141, at least one of the inlet 1164a and outlet 1164b of the electric pump 1141 can communicate with the corresponding flow channel cavity 112 through the mounting part 121, and the electric pump 1141 can provide power for the flow of coolant. As a specific embodiment, the fluid management device 114 includes an electric pump 1141 and an electric valve 1142. The flow channel plate assembly 11 includes an interface part 113, which is connected to an external pipe. Coolant outside the interface part 113 can enter the flow channel cavity 112 through the interface part 113, or coolant inside the flow channel cavity 112 can be transported to the outside of the integrated assembly 100 through the interface part 113. Define a first direction 101 and a second direction 102. The extension length of the flow channel plate assembly 11 in the first direction 101 is greater than the extension length in the second direction 102. The first direction 101 is perpendicular to the second direction 102, and the third direction 103 is perpendicular to both the first direction 101 and the second direction 102.

[0030] Please see Figures 1 to 9As shown, the flow channel plate assembly 11 can be made of the same type or a single material, including plastic, metal, rubber, or other materials. These materials can also be a combination of multiple materials, such as plastic and metal. The metals mentioned herein include aluminum and aluminum alloys. The flow channel plate assembly 11 is assembled from multiple components, such as multiple stacked components, which can be fixedly connected by welding. In one specific embodiment, the flow channel plate assembly 11 includes at least two components, both made of the same material, specifically plastic. In this embodiment, the flow channel plate assembly 11 includes a base 116 and a cover 117. The base 116 includes a main portion 1161 and multiple baffles fixedly connected to or integrally designed with the main portion 1161. These baffles form the walls corresponding to the flow channel cavity. The base 116 and the cover 117 are welded together, and the welding methods include, but are not limited to, laser welding, infrared welding, hot plate welding, or ultrasonic welding.

[0031] In thermal management systems, the working medium flowing through the flow chamber often generates bubbles due to temperature changes or vehicle vibrations. If these bubbles are not separated, it will affect both the performance of the water pump and the overall heat exchange efficiency of the thermal management system. In related technical solutions, the opening connecting the gas separator chamber to the expansion tank is positioned close to the liquid inlet of the flow channel plate assembly. Consequently, bubbles exiting the gas separator chamber enter the liquid inlet without sufficient degassing, resulting in low exhaust efficiency for the entire integrated assembly.

[0032] As one implementation method, please refer to Figures 1 to 9As shown, an integrated component 100 includes a flow channel plate assembly 11. The flow channel plate assembly 11 includes a flow channel portion 111 and a gas collection portion 115. The flow channel portion 111 has a flow channel cavity 112, and the gas collection portion 115 has a gas collection cavity 1153. The gas collection cavity 1153 includes a first opening 1151 and a second opening 1152. The first opening 1151 communicates with the flow channel cavity 112, and the second opening 1152 is formed on the outer wall of the flow channel plate assembly 11. The flow channel plate assembly 11 includes a liquid replenishment portion 120, which includes a liquid replenishment cavity 1201 that communicates with the flow channel cavity 112. The liquid replenishment cavity 1201 includes a liquid replenishment port 1202, which is formed on the outer wall of the flow channel plate assembly 11. The liquid replenishment port 1202 and the second opening 1152 are spaced apart. This provides a foundation for setting other structures (such as degassing structures) between the liquid replenishment port 1202 and the second opening 1152. Furthermore, the bubbles discharged from the second opening 1152 can be fully degassed, and the fully degassed working medium can then enter the flow channel cavity 112 through the liquid replenishment port 1202. Compared with the technical solution where the liquid replenishment port 1202 and the second opening 1152 are placed close together, this method helps to reduce the number of bubbles discharged from the second opening 1152 that have not been fully degassed before entering the liquid replenishment port. Thus, this method helps to improve the exhaust efficiency of the integrated component.

[0033] As one implementation method, please refer to Figures 1 to 9As shown, an integrated component 100 includes an expansion tank 13 and a flow channel plate assembly 11. The expansion tank 13 has a liquid storage chamber 135. The flow channel plate assembly 11 includes a flow channel portion 111 and a gas collecting portion 115. The flow channel portion 111 has a flow channel cavity 112, and the gas collecting portion 115 has a gas collecting cavity 1153. The gas collecting cavity 1153 includes a first opening 1151 and a second opening 1152. The first opening 1151 communicates with the flow channel cavity 112, and the second opening 1152 communicates with the liquid storage chamber 135. The flow channel plate assembly 11 includes a liquid replenishment portion 120 with a liquid replenishment port 1202 communicating with the liquid storage chamber 135. The expansion tank 13 includes a degassing structure 136 with a degassing channel 1361. The degassing channel 1361 includes a first port 1361a. The first port 1361a is connected to the second opening 1152, and the second port 1361b is connected to the replenishment port 120. The degassing structure 136 includes a first partition 1362 and a second partition 1363. Along the length of the expansion tank 13, the first partition 1362 and the second partition 1363 are spaced apart by a preset distance. At least a portion of the wall corresponding to the first port 1361a is formed in the first partition 1362, and at least a portion of the wall corresponding to the second port 1361b is formed in the second partition 1363. The wall corresponding to the first port 1361a and the wall corresponding to the second port 1361b are projected onto the plane where the first partition 1362 is located. The projection of the wall corresponding to the first port 1361a and the projection of the wall corresponding to the second port 1361b do not coincide. In this way, the working medium returns to the flow channel plate assembly 11. When the working medium enters the gas collecting chamber 1153, the air bubbles entrained in the working medium can be released into the gas collecting chamber 1153 and collect at the second opening 1152, flowing into the expansion tank 13. Thus, firstly, no separate pipeline or separate gas-liquid separation structure is needed, which is beneficial for the lightweighting of the thermal management system. Secondly, the expansion tank 13 does not require a special degassing structure to separate the gas and liquid in the thermal management system, which simplifies the structure of the expansion tank 13. Third, a degassing structure 136 is provided between the second opening 1152 and the liquid replenishment port 1202. The degassing channel includes a first port 1361a and a second port 1361b. The first port 1361a is connected to the second opening 1152, and the second port 1361b is connected to the liquid replenishment port 1202. The degassing structure 136 includes a first partition 1362 and a second partition 1363. Along the length direction of the expansion tank 13, specifically, in this embodiment, the length direction of the expansion tank 13 is parallel to the third direction 103. The first partition 1362 and the second partition 1363 are spaced apart by a preset distance. The first port 1361a is formed in the first partition 1362, and the second port 1361b is formed in the second partition 1363. Specifically, the first partition 1362 and the second partition 1363 are approximately parallel to the second direction 102.Projecting the wall portions corresponding to the first port 1361a and the second port 1361b onto the plane where the first partition 1362 is located, the projections of the wall portions corresponding to the first port 1361a and the second port 1361b do not coincide. It can be understood that the second opening 1152 and the liquid replenishment port 1202 are spaced a certain distance apart. The air bubbles discharged from the second opening 1152 can be fully degassed within the liquid storage chamber. The fully degassed working medium then enters the flow channel chamber through the liquid replenishment port 1202. Compared to the technical solution where the liquid replenishment port 1202 and the second opening 1152 are placed adjacent to each other, this method helps reduce the number of air bubbles discharged from the second opening 1152 that have not been fully degassed before entering the liquid replenishment port 1202. Therefore, this method helps improve the exhaust efficiency of the integrated component. It should be noted that, in the above and below, the length direction of the expansion tank 13 is parallel to the third direction 103, the height direction of the expansion tank 13 is parallel to the first direction 101, and the width direction of the expansion tank 13 is parallel to the second direction 102.

[0034] As a specific implementation method, please refer to Figures 2 to 6 As shown, the flow channel plate assembly 11 includes a base 116 and a cover 117. The base 116 includes a main body 1161. A first stop 118 and a second stop 119 are both fixedly connected to the base 116, or the first stop 118 and the second stop 119 are integral structural components with the base 116. The cover 117 is fixedly connected to the base 116. The fixed connection between the cover 117 and the base 116 includes, but is not limited to, welding, bonding, snap-fitting, or fixed connection using fasteners. In this embodiment, the first stop 118 and the second stop 119 are integral structural components with the main body 1161. This simplifies the number of components in the flow channel plate assembly 11, thereby facilitating the manufacturing and processing of the integrated assembly 100.

[0035] As one implementation method, please refer to Figures 1 to 6 As shown, the flow channel cavity 112 includes an inlet end 1122 and an outlet end 1123. The first opening 1151 is closer to the inlet end 1122 than the outlet end 1123, and the cross-sectional area of ​​the first opening 1151 is larger than the cross-sectional area of ​​the second opening 1152. In this way, air bubbles in the flow channel cavity can quickly enter the gas collection cavity, which helps to improve the exhaust efficiency of the integrated component.

[0036] As one implementation method, please refer to Figures 1 to 6As shown, along the height direction of the expansion tank 13, the second opening 1152 is closer to the expansion tank 13 than the first opening 1151. The wall portion corresponding to the gas collecting chamber 1153 includes a first baffle 118 and a second baffle 119. Along the direction from the first opening 1151 to the second opening 1152, the distance between the first baffle 118 and the second baffle 119 tends to decrease. Thus, in the gas-liquid mixed working medium, the gas is more easily separated and moves towards the second opening 1152, while the liquid moves towards the first opening 1151 under the action of gravity. Therefore, it participates in the circulation of the working medium of the thermal management system along with the main circulating working medium in the flow channel cavity 112.

[0037] To further increase the cross-sectional area of ​​the air collection chamber 1153 for flow, please refer to the following specific implementation method: Figures 1 to 6 As shown, the first baffle 118 includes a first sub-baffle 1181 and a second sub-baffle 1182. The first sub-baffle 1181 and the second sub-baffle 1182 are connected. The second sub-baffle 1182 is closer to the second opening 1152 than the first sub-baffle 1181. Projecting the first sub-baffle 1181 and the second sub-baffle 1182 onto a plane perpendicular to the first baffle 118, the projection structure of the first sub-baffle 1181 is arc-shaped, and the structure of the second sub-baffle 1182 is straight. The arc-shaped structure is recessed from inside the gas collecting chamber to outside. In this way, within the limited space of the flow channel plate, the space of the flow channel plate assembly can be utilized as much as possible, making the space of the gas collecting chamber as large as possible. This allows for: firstly, rapid and efficient separation of the working medium containing air bubbles, enabling the separated working medium to quickly participate in the circulation of the main circulation path; and secondly, the arc-shaped structure is more conducive to the accumulation of gas towards the second opening 1152, which is more beneficial for gas-liquid separation.

[0038] Furthermore, as a means of implementation, [the text abruptly ends here]. Figures 1 to 6 As shown, the first baffle 118 includes a first end portion 1183 and a second end portion 1184. The first end portion 1183 is formed in the first sub-baffle 1181, and the second end portion 1184 is formed in the second sub-baffle 1182. The second end portion 1184 is fixedly connected to the expansion tank 13. The second baffle 119 includes a third end portion 1191 and a fourth end portion 1192. The third end portion 1191 is fixedly connected to the expansion tank 13. The wall portion corresponding to the first opening 1151 includes the first end portion 1183 and the fourth end portion 1192. The fourth end portion 1192 is closer to the expansion tank 13 than the first end portion 1183. In this way, it is beneficial to increase the cross-sectional area of ​​the flow at the first opening, which is more conducive to the collection of bubbles into the gas collecting chamber, thereby improving the exhaust efficiency of the integrated component.

[0039] The circulating working medium in a thermal management system is affected by temperature. Please refer to [reference needed]. Figures 1 to 9As shown, the working medium needs to be replenished in the thermal management system. The flow channel plate assembly 11 includes a replenishment section 120, which has a replenishment chamber 1201. One end of the replenishment chamber 1201 is connected to the expansion tank 13, and the other end is connected to the flow channel cavity 112. In this embodiment, the thermal management system includes an expansion tank. The working medium in the expansion tank can enter the flow channel plate assembly through the replenishment chamber of the replenishment section 120 to replenish the working medium of the entire thermal management system.

[0040] As a specific implementation method, please refer to Figures 1 to 9 As shown, the flow channel plate assembly 11 includes at least one mounting portion 121, which has a mounting cavity 1211. An outlet end 1123 communicates with the mounting cavity 1211. The integrated assembly 100 includes at least one electric pump 1141. The pump inlet 1141a of the at least one electric pump 1141 communicates with the mounting cavity 1211. A liquid replenishment port 1202 is located upstream of the second opening 1152 relative to the pump inlet 1141a. In this way, the working medium entering the water pump is the working medium after passing through the gas collecting section 115. That is, the working medium entering the water pump is the working medium after gas-liquid separation. This helps to reduce the impact of air bubbles on the water pump performance and improves the service life of the water pump.

[0041] As a specific implementation method, please refer to Figures 1 to 9 As shown, the integrated component 100 includes an expansion tank 13, which has a liquid storage chamber 135. The wall corresponding to the liquid storage chamber 135 includes a bottom 131. The expansion tank 13 includes a connecting port 132, which extends through the bottom 131 and communicates with a second opening 1152. The expansion tank 13 is fixedly connected to the flow channel plate assembly 11, specifically, by welding. Welding methods include, but are not limited to, infrared welding, laser welding, and hot plate welding. Integrating the expansion tank into the flow channel plate assembly facilitates the miniaturization of the entire thermal management system. In this embodiment, the thickness of the expansion tank extending in the second direction is greater than the thickness of the base extending in the second direction. This allows for full utilization of the vehicle's layout space. Specifically, along the second direction 102, the flow channel plate assembly 11 is positioned approximately in the middle of the expansion tank.

[0042] As a specific implementation method, please refer to Figures 1 to 9 As shown, the expansion kettle 13 includes an upper kettle body 138 and a lower kettle body 137; the upper kettle body 138 and the lower kettle body 137 are welded and fixed together. The bottom 131 is formed in the lower kettle body 137.

[0043] In one specific embodiment, the expansion vessel 13 includes an extension portion 133, which is fixedly connected to the bottom 131. The extension portion 133 includes an extension channel 1331, with a connecting port 132 formed at one end of the extension channel 1331. The other end of the extension channel 1331 communicates with the liquid storage chamber 135. In this way, gas can be further concentrated in the extension channel 1331 and released into the expansion vessel 13 through the end of the extension channel 1331, thus helping to reduce the generation of large bubbles in the expansion vessel 13.

[0044] Furthermore, to further reduce the generation of large air bubbles within the expansion vessel 13, the expansion vessel 13 has a baffle portion 134, which is arranged parallel to the bottom 131. The baffle portion 134 is fixedly connected to the wall portion corresponding to the liquid storage chamber 135. One end of the baffle portion 134 is at a predetermined distance from the wall portion 135, and the other end of the baffle portion 134 has a channel hole 1341. In this way, it is more effective to separate large air bubbles into smaller air bubbles, which helps to reduce the "boiling" phenomenon of the working medium within the expansion vessel.

[0045] 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.
