Detailed Implementation

[0037] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the following description of the present invention with reference to the accompanying drawings is merely illustrative and not restrictive. Various different embodiments can be combined with each other to form other embodiments not shown in the following description.

[0038] Please see Figures 1-22 This invention provides a connecting device that can be used in a thermal management assembly. The connecting device includes two or more plates, which are fixedly and sealed together. The connecting device has a channel, and at least one of the adjacent plates has at least one channel portion inside, forming a channel at the channel portion. A mounting portion and / or a connecting portion are provided along one of the sidewalls of at least one plate along the axial or radial direction of the connecting device. The mounting portion has a mounting hole. The thermal management assembly includes a valve device capable of controlling the flow rate or on / off state of the channel. At least a portion of the valve device is located within the mounting hole. The channel communicates with the mounting hole of at least one mounting portion. The connecting portion has a connecting hole. The thermal management assembly also includes a thermal management unit, and one of the inlet and outlet of at least one thermal management unit communicates with the connecting hole. The channel communicates with at least one connecting hole.

[0039] Understandably, the mounting section is used to mount the valve device onto the plate. The mounting section also has mounting holes, allowing the channel to connect with the valve device through these holes. The connecting section has connecting holes that connect with the inlet and outlet of the thermal management unit. Fluid media flows through the channel and the corresponding devices. Since there are two or more plates, adjacent plates form a channel at the channel section. The channel can be formed by multiple channel sections, increasing the internal space of the channel and allowing it to store more fluid media. Simultaneously, the connecting device can form complex spatial channels, enabling the installation of valve devices and thermal management units in multiple thermal management components, and meeting the different layout requirements of different devices. This ensures that the device layout is not limited by location and improves the utilization rate of internal space.

[0040] The aforementioned plates can be made of materials such as aluminum alloy. Before welding, at least one of the adjacent plates can be coated with a composite weld layer at the joint surface, allowing the plate with the composite weld layer to be welded and fixed to its adjacent plate. Alternatively, a solder layer can be provided between two adjacent plates to weld and fix the adjacent plates. The material of the solder layer can refer to existing technologies. Or, a third plate with a double-sided composite weld layer can be provided between adjacent plates. The aforementioned fluid medium can be refrigerant, coolant, or cooling oil used in vehicle thermal management systems.

[0041] The same channel can be formed by connecting and enclosing multiple adjacent corresponding channel sections. For example, the same channel can have a partial sidewall formed by channel sections set within two, three, or four plates. Moreover, different channels in the connecting device can be composed of different and / or the same number of plates. For example, the connecting device includes five plates, one of which can have a partial sidewall formed by a channel section between two plates, while another channel can have a partial sidewall formed by channel sections set within three plates.

[0042] In this device, at least one sidewall of a plate is provided with a mounting portion and / or a connecting portion along the axial or radial direction of the connecting device. For example, a mounting portion and a connecting portion are provided on one sidewall of a plate along the axial direction of the connecting device. The mounting portion is provided with a mounting hole, and a partial valve device is disposed within the mounting portion. The channel is connected to the mounting hole. The connecting portion has a connecting hole, and the inlet and outlet of the thermal management unit are connected to the connecting hole. The connecting hole is connected to the channel. Two mounting portions are provided on the two sidewalls of the two plates, and each sidewall is provided with a corresponding mounting portion. The mounting portion is provided with a mounting hole, and a corresponding partial valve device is disposed in each mounting hole.

[0043] The communication device provided by the present invention will be further described below with reference to specific embodiments.

[0044] Please see Figures 1-14In Embodiment 1 of the present invention, the connecting device includes five plates, defined from top to bottom as a first plate 1a, a second plate 2a, a third plate 3a, a fourth plate 4a, and a fifth plate 5a. The second plate 2a is located between the first plate 1a and the third plate 3a, and the fourth plate 4a is located between the third plate 3a and the fifth plate 5a. The channel portions of the second plate 2a and the fourth plate 4a are both through grooves 7a, while the channel portions of the first plate 1a and the fifth plate 5a are both grooves 6a. The third plate 3a includes two channel portions, both of which are grooves 6a. One of the grooves 6a in the third plate 3a is defined as... A is a first groove 61a, and the other groove 6a is a second groove 62a. The channel 8 includes a first channel 81a and a second channel 82a. The groove 6a of the first plate 1a, the through groove 7a of the second plate 2a, and the first groove 61a of the third plate 3a form the first channel 81a. The second groove 62a of the third plate 3a, the through groove 7a of the fourth plate 4a, and the groove 6a of the fifth plate 5a form the second channel 82a. The second plate 2a is coated with a composite weld layer on the surfaces where it connects with the first plate 1a and the third plate 3a. The fourth plate 4a is coated with a composite weld layer on the surfaces where it connects with the third plate 3a and the fifth plate 5a. In other embodiments, only a portion of the second plate 2a may be located between the first plate 1a and the third plate 3a, and only a portion of the fourth plate 4a may be located between the third plate 3a and the fifth plate 5a.

[0045] It is understood that in this embodiment, the groove 6a of the first plate 1a, the through groove 7a of the second plate 2a, and the first groove 61a of the third plate 3a form the first channel 81a, such as... Figure 1 and Figure 7 As shown, the through groove 7a of the second plate 2a has the same shape as the first channel 81a. There is one first channel 81a, and the first channel 81a is arc-shaped.

[0046] The second groove 62a of the third plate 3a, the through groove 7a of the fourth plate 4a, and the groove 6a of the fifth plate 5a form the second channel 82a, such as Figure 2 and Figure 9As shown, the through groove 7a of the fourth plate 4a has the same shape as the second channel 82a. There are two second channels 82a, which are "T" shaped and "J" shaped respectively. The "T" shaped second channel 82a has three ends, each end of which is connected to the corresponding mounting hole. The "J" shaped second channel 82a has two ends, each end of which is connected to the corresponding mounting hole or connecting hole. This allows the second channel 82a to be connected to the valve device installed on the corresponding mounting part (i.e., the first mounting part 91 and the second mounting part 92) through the mounting hole, and to the thermal management unit installed on the corresponding connecting part (i.e., the first connecting part 310 and the second connecting part 320) through the connecting hole.

[0047] Since multiple valve devices and thermal management units need to be installed, five plates are stacked to maximize the use of the positions on the plates where the first channel 81a or the second channel 82a is not provided. The stacked plates form a complex spatial channel, which meets the different layout requirements of different devices, reduces the limitation of device layout by location, and improves the utilization rate of internal space.

[0048] It should be understood that the shape and number of the first channel 81a and the second channel 82a described above can be set according to the actual needs of the thermal management component.

[0049] Among them, such as Figure 1-2 As shown, the mounting part includes a first mounting part 91, and the connecting part includes a first connecting part 310. The first mounting part 91 and the first connecting part 310 are arranged along the axial direction of the connecting device. The first mounting part 91 and the first connecting part 310 protrude from the plates located at both ends of the connecting device. The mounting hole includes a first mounting hole 110, and the first connecting part 310 includes a first connecting hole 410. The first mounting hole 110 and the first connecting hole 410 are axially formed on the plate and communicate with the channel. At least a portion of the valve device is inserted into the first mounting hole 110, and at least a portion of the inlet and outlet of the thermal management unit communicates with the first connecting hole 410.

[0050] The mounting section includes a second mounting section 92, and the connecting section includes a second connecting section 320, which is arranged along the extension direction of the connecting device and the extension direction is perpendicular to the axis of the connecting device. The second mounting section 92 and the second connecting section 320 protrude from the plates located at both ends of the connecting device. The mounting hole includes a second mounting hole 120, and the second connecting section 320 has a second connecting hole 420. The extension directions of the second mounting hole 120 and the second connecting hole 420 are parallel to the extension direction. The second mounting hole 120 and the second connecting hole 420 are formed on the sidewalls of adjacent plates and communicate with the channel. At least a portion of the valve device is inserted into the second mounting hole 120, and at least a portion of the inlet and outlet of the thermal management unit communicates with the second connecting hole 420.

[0051] The valve device described above can be a throttling element, a solenoid valve, or a switching valve; the thermal management unit described above can be a heat exchanger or a liquid reservoir; the throttling element is, for example, an electronic expansion valve; the heat exchanger is, for example, a Chiller.

[0052] It should be noted that, according to the requirements of the vehicle thermal management system, corresponding components can be installed on the mounting part, and the mounting hole can be connected to the valve device. Corresponding components can also be installed on the connecting part, and the connecting hole can be connected to the inlet and outlet of the thermal management unit. In one embodiment, the first electronic expansion valve is connected to the first mounting part 91, with one part of the first electronic expansion valve inserted into the first mounting hole 110. After the first electronic expansion valve is installed in the first mounting hole 110, it is connected to the first channel 81a through the first mounting hole 110. The reservoir is connected to the first connecting part 311, with the inlet of the reservoir connected to the first connecting hole 412 and the outlet of the reservoir connected to the first connecting hole 413. The reservoir is connected to one end of the "J"-shaped second channel 82a through the first connecting hole 412, and to the "T"-shaped second channel 82a through the first connecting hole 413. The second electronic expansion valve is connected to the first mounting part 911, with one part of the second electronic expansion valve inserted into the first mounting hole 111. After the valve is installed in the first mounting hole 111, it is connected to one end of the "T"-shaped second channel 82a through the first mounting hole 111; the third electronic expansion valve is connected to the first mounting part 912, and one part of the third electronic expansion valve is inserted into the first mounting hole 112. After the third electronic expansion valve is installed in the first mounting hole 112, it is connected to one end of the "T"-shaped second channel 82a through the first mounting hole 112; the heat exchanger is connected to the first connecting part 310, the inlet of the heat exchanger is connected to the first connecting hole 410, the outlet of the heat exchanger is connected to the first connecting hole 411, and the heat exchanger is connected to the first channel 81a through the first connecting hole; the second mounting hole 120 is connected to the outlet of the third electronic expansion valve; the second connecting hole 420 is connected to the outlet of the heat exchanger.

[0053] The third plate 3a includes a thick part 31a and a thin part. The upper surface of the thick part 31a is welded and fixed to the second plate 2a and sealed. The lower surface of the thin part and the lower surface of the thick part 31a are both welded and fixed to the fourth plate 4a and sealed. A corresponding first groove 61a is formed on the thick part 31a and a corresponding second groove 62a is formed on the thin part.

[0054] It is understandable that the second groove 62a formed on the thin body protrudes in the direction close to the second plate 2a, and it is difficult to install other plates at the location where the second groove 62a is provided on the upper surface of the thin body, such as Figure 8As shown, by providing the thick body portion 31a, not only can part of the second groove 62a be covered, thus providing space for the installation of other plates, but also the space of the third plate 3a without the second groove 62a can be maximized. At the same time, by providing the thick body portion 31a, the lower surface of the thick body portion 31a where the first groove 61a is formed is flat, so that the lower surface of the thick body portion 31a and the fourth plate 4a can be welded and fixed, effectively preventing unevenness of the welding contact surface.

[0055] In this embodiment, the cross-sectional areas of the first plate 1a and the second plate 2a are both smaller than the cross-sectional area of ​​the thick body 31a; the fourth plate 4a, the fifth plate 5a, and the third plate 3a all have the same shape and dimensions. In other embodiments, the cross-sectional areas of the second plate 2a and the first plate 1a can be equal to the cross-sectional area of ​​the thick body 31a.

[0056] It is understandable that the second plate 2a and the first plate 1a are stacked sequentially on the thick body 31a. The space in the third plate 3a where the second groove 62a is not provided can be maximized, and unevenness of the welding contact surface can be prevented. The shape and size of the fourth plate 4a, the fifth plate 5a and the third plate 3a are set to be the same to facilitate welding and fixing.

[0057] Please continue reading. Figures 1-2 as well as Figures 6-14 The connecting device provided in this embodiment can be manufactured by the following steps:

[0058] S1. Five blank plates are provided. Mounting parts and connecting parts are provided on the walls of two blank plates along the axial and radial directions of the connecting device. That is, from top to bottom, mounting parts and connecting parts are provided on the side walls of the first blank plate and the fifth blank plate. Then, channel parts are formed in the adjacent blank plates to obtain plates with channel parts (i.e., first plate 1a, second plate 2a, third plate 3a, fourth plate 4a and fifth plate 5a).

[0059] Among them, such as Figure 6 The image shows a first plate 1a, on which a groove 6a is formed; as shown Figure 7 The second plate 2a is shown, and a through groove 7a is formed on the second plate 2a; as shown Figure 8 The third plate 3a is shown. A first groove 61a is formed on the third plate 3a. The groove 6a, a through groove 7a, and the first groove 61a form a first channel 81a.

[0060] like Figure 8 As shown, a second groove 62a is also formed on the third plate 3a, and the third plate 3a includes a thick part 31a and a thin part 32a.

[0061] like Figure 9 The fourth plate 4a is shown, and two through grooves 7a are formed on the fourth plate 4a.

[0062] like Figures 10-11 The fifth plate 5a is shown. Two grooves 6a are formed on the fifth plate 5a. The second groove 62a and the through groove 7a and the groove 6a form a second channel 82a. The fifth plate 5a is provided with a first connecting part 310.

[0063] S2, connect adjacent plates (such as...) Figure 12 The first plate 1a, the second plate 2a, the third plate 3a, the fourth plate 4a, and the fifth plate 5a shown are stacked sequentially, and adjacent plates are welded, fixed, and sealed together to obtain the following: Figure 14 The first channel 81a shown, and as shown Figure 13 The second channel 82a is shown.

[0064] S3. A mounting hole is formed in the mounting portion on the sealed plate to obtain a communicating device, and as shown in the figure. Figures 1-2 The connecting device shown.

[0065] Understandably, the blank plate is processed, for example, by forging, stamping, or casting, to obtain a plate with a channel section. The connecting surfaces of the second plate 2a with the first plate 1a and the third plate 3a are coated with a composite weld layer, and the connecting surfaces of the fourth plate 4a with the third plate 3a and the fifth plate 5a are also coated with a composite weld layer. During welding, the plate is heated until the weld layer melts, causing the liquid weld layer on the second plate 2a to diffuse onto the surfaces of the first plate 1a and the third plate 3a, and the liquid weld layer on the fourth plate 4a to diffuse onto the surfaces of the third plate 3a and the fifth plate 5a. After cooling, the second plate 2a is welded and fixed to the first plate 1a and the third plate 3a and sealed, and the fourth plate 4a is welded and fixed to the third plate 3a and the fifth plate 5a and sealed. After welding, according to the different valve device settings, corresponding mounting holes are machined on each mounting part, and according to the different thermal management unit settings, corresponding connecting holes are machined on each connecting part.

[0066] Please see Figure 15 As shown, in Embodiment 2 of the present invention, the connecting device includes two plates, one of which is defined as the first plate 1b, and the plate adjacent to the first plate 1b is defined as the second plate 2b. The channel portion on the first plate 1b and the channel portion on the second plate 2b are both grooves 6b. The first plate 1b and the second plate 2b are fixedly and sealed together, and the two grooves 6b are connected to form a channel.

[0067] It is understood that the channel is connected to the mounting hole in the mounting part, and the channel is also connected to the connecting hole in the connecting part. In this embodiment, two channels are provided. In other embodiments, the shape and number of channels can be changed according to the setting requirements of the thermal management component, so that the arrangement of the thermal management component is not limited by the position, thereby improving the space utilization rate.

[0068] It should be noted that, according to the requirements of the vehicle thermal management system, corresponding components can be installed on the mounting section, and the mounting hole can be connected to the valve device. Corresponding components can be installed on the connecting section, and the connecting hole can be connected to the inlet and outlet of the thermal management unit.

[0069] The welding layer can be set in different ways. In this embodiment, the surface of the first plate 1b coated with the composite welding layer is fused and welded to the second plate 2b.

[0070] In another embodiment, before welding, a solder layer is provided between the first plate 1b and the second plate 2b. After welding, the solder layer melts and diffuses onto the first plate 1b and the second plate 2b, thereby welding and fixing the first plate 1b and the second plate 2b together.

[0071] Please see Figures 16-18 As shown, in Embodiment 3 of the present invention, the connecting device includes three plates. One of the plates is defined as the first plate 1c, the plate adjacent to the first plate 1c is the second plate 2c, and the plate adjacent to the second plate 2c is the third plate 3c. The second plate 2c is located between the first plate 1c and the third plate 3c. One side of the second plate 2c is fixed and sealed to the first plate 1c, and the other side of the second plate 2c is fixed and sealed to the third plate 3c. The channel portion on the second plate 2c is a through groove 7c, and the channel portions on the first plate 1c and the third plate 3c are both grooves 6c. The adjacent plates are welded and fixed. Before welding, a composite weld layer is applied to the connecting surfaces of the second plate 2c with the first plate 1c and the third plate 3c. In other embodiments, only a portion of the second plate 2c may be located between the first plate 1c and the third plate 3c.

[0072] It is understandable that there are two channels 8, each channel 8 is formed by two grooves 6c and a through groove 7c, which increases the internal space of the channel 8 and can store more fluid medium. The connection surfaces of the second plate 2c with the first plate 1c and the third plate 3c are coated with a composite welding layer. The composite welding layer set on the second plate 2c is used to weld and fix the first plate 1c and the third plate 3c.

[0073] It should be noted that, according to the requirements of the vehicle thermal management system, corresponding components can be installed on the mounting section, and the mounting hole can be connected to the valve device. Similarly, corresponding components can be installed on the connecting section, and the connecting hole can be connected to the inlet and outlet of the thermal management unit. In one embodiment, a portion of the switching valve is located within the first mounting hole, and the switching valve is connected to one of the channels 8 through the first mounting hole. The first connecting hole in the first connecting section is connected to the inlet and outlet of the liquid reservoir, and the liquid reservoir is connected to another channel 8 through the first connecting hole.

[0074] The inner wall of channel 8 is arc-shaped, which can be understood to reduce the resistance of the fluid medium flowing through channel 8 and reduce the resistance loss of the fluid medium.

[0075] Please see Figures 19-22 As shown, in Embodiment 4 of the present invention, the communicating device includes three plates. From top to bottom, one plate is defined as the first plate 1d, the plate adjacent to the first plate 1d is the second plate 2d, and the plate adjacent to the second plate 2d is the third plate 3d. The second plate 2d is located between the first plate 1d and the third plate 3d. The channel portions of the first plate 1d and the third plate 3d are both grooves 6d. The second plate 2d includes two channel portions, both of which are grooves 6d. Define one groove 6d of the second plate 2d as the first groove 61d and the other groove 6d as the second groove 62d. The channel includes a first channel 81d and a second channel 82d. The groove 6d of the first plate 1d and the first groove 61d of the second plate 2d form the first channel 81d, and the second groove 62d of the second plate 2d and the groove 6d of the third plate 3d form the second channel 82d. The channel communicates with a corresponding valve device through a mounting hole and with a corresponding thermal management unit through a connecting hole. In other embodiments, the second plate 2d may only be partially located between the first plate 1d and the third plate 3d.

[0076] The weld layer can be configured in different ways. In one embodiment, the first plate 1d, the second plate 2d, and the third plate 3d are welded, fixed, and sealed together. Figure 20 As shown, a first solder layer 200 is provided between the first plate 1d and the second plate 2d before welding, and a through groove is formed on the first solder layer 200. A second solder layer 210 is provided between the second plate 2d and the third plate 3d, and a through groove is formed on the second solder layer 210. The first plate 1d and the second plate 2d are fused and welded through the first solder layer 200, and the second plate 2d and the third plate 3d are fused and welded through the second solder layer 210.

[0077] It is understandable that the first plate 1d and the second plate 2d are welded and sealed together by the first solder layer 200, and the second plate 2d and the third plate 3d are welded and sealed together by the second solder layer 210. After welding, the first solder layer 200 and the second solder layer 210 dissolve and diffuse into the surface of the adjacent plates, reducing the thickness and height of the connecting device, making the overall structure more compact and reducing the space occupied in the vehicle interior.

[0078] In another embodiment, the difference from the previous embodiment is that the surface of the first plate 1d coated with the composite welding layer is welded and fixed to the second plate 2d, and the surface of the second plate 2d away from the first plate 1d is coated with the composite welding layer and welded and fixed to the third plate 3d.

[0079] The present invention also provides a thermal management component, including a thermal management unit, a valve device, and a connecting device, the structure of which can be found in [reference needed]. Figures 1-22 The thermal management unit includes at least one of a heat exchange section and a liquid reservoir; the valve device includes at least one of a throttling element, a solenoid valve, and a switching valve; the connecting device includes two or more plates, adjacent plates are fixed and sealed together, the connecting device has a channel, at least one channel portion is provided inside at least one of the adjacent plates, and the adjacent plates form a channel at the channel portion; wherein, a mounting portion and / or a connecting portion are provided on one of the side walls of at least one plate along the axial or radial direction of the connecting device; the mounting portion has a mounting hole, at least a portion of the valve device is located in the mounting hole, the connecting portion has a connecting hole, and at least a portion of the inlet and outlet of the thermal management unit communicates with the connecting hole.

[0080] Understandably, when multiple thermal management components need to be set up, such as heat exchangers, reservoirs, throttling elements, solenoid valves, and switching valves, multiple plates can be stacked as needed. Adjacent plates form channels at the passage section, and the connecting devices can form complex spatial channels, so that the layout of parts in the vehicle thermal management system is not restricted by location, thus improving the space utilization rate within the vehicle thermal management system.
