Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention.

[0030] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh", "eighth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, terms such as "horizontal", "vertical", "hanging" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0034] It should be noted that the terms "upper" and "lower" are referenced to the drawings and are not limitations on the orientation.

[0035] As Figures 1 to 7 shown, an embodiment of the present invention provides a fluid control integrated device base, including: a mounting base 1, a liquid storage tank 3, and a communication base 2; the mounting base 1 is connected to the liquid storage tank 3, and the liquid storage tank 3 is connected to the communication base 2; a plurality of valve cavities are provided on the communication base 2, wherein at least part of the valve cavities are communicated with the liquid storage tank 3, and at least part of the valve cavities can communicate with each other.

[0036] In this embodiment, the mounting base 1 can be installed on the mounting substrate, so as to install the fluid control integrated device at a specified position. Corresponding valves can be installed in a plurality of valve cavities, wherein there are valves communicated with the liquid storage tank 3, and there are some valves communicating with each other. The fluid control integrated device base provided by this embodiment can integrate a plurality of valves and the liquid storage tank 3 together, avoiding the setting of complex pipelines, making the structure of the fluid integrated device simple and occupying less space, thereby making the structure of the thermal management system simple and occupying less space. In addition, the fluid control integrated device base provided by this embodiment can also avoid the disadvantage that long pipelines are not conducive to fluid flow.

[0037] Among them, the connecting seat 2 and the liquid storage tank 3 can be separately and independently arranged, and the connection and fixation between the connecting seat 2 and the liquid storage tank 3 are realized through welding, threaded connection or clamping.

[0038] As an alternative solution, as Figure 2 shown, the connecting seat 2 includes a connecting plate 201 and a valve cavity base body 202 connected to the connecting plate 201; a valve cavity is provided on the valve cavity base body 202; one side of the liquid storage tank 3 is provided with an opening, and the connecting plate 201 is connected to the opening to cover the opening.

[0039] In this embodiment, the connecting plate 201 in the connecting seat 2 can be used as a part of the liquid storage tank 3, so as to further simplify the structure of the fluid control integration device. It should be noted that an interface can be provided on the connecting plate 201 to realize the communication between part of the valve cavity and the inner cavity of the liquid storage tank 3.

[0040] Among them, the connecting plate 201 and the liquid storage tank 3 can be connected and fixed by welding, with firm connection and reliable sealing.

[0041] Specifically, as Figures 1 to 5 shown, among the multiple valve cavities, there is an electromagnetic valve valve cavity 203. The electromagnetic valve valve cavity 203 includes an electromagnetic valve valve port 2031, an electromagnetic valve upper cavity 2032 and an electromagnetic valve lower cavity 2033 that are connected in sequence. The diameter of the electromagnetic valve upper cavity 2032 is more than 1.1 times the diameter of the electromagnetic valve valve port 2031.

[0042] In this embodiment, the electromagnetic valve upper cavity 2032 and the electromagnetic valve lower cavity 2033 are penetrated by an electromagnetic valve 5. The diameter of the electromagnetic valve upper cavity 2032 is more than 1.1 times the diameter of the electromagnetic valve valve port 2031, so the gap between the electromagnetic valve 5 and the electromagnetic valve valve cavity 203 is increased, the fluid resistance can be reduced, and it is beneficial to the fluid flow.

[0043] Among them, as Figures 2 to 4 shown, the number of the electromagnetic valve valve cavities 203 is multiple, including a first electromagnetic valve valve cavity 2034, a second electromagnetic valve valve cavity 2035 and a third electromagnetic valve valve cavity 2036; a first channel 205, a second channel 206, a third channel 207, a fourth channel 208 and a fifth channel 209 are provided on the valve cavity base body 202; the electromagnetic valve upper cavity 2032 of the first electromagnetic valve valve cavity 2034 and the electromagnetic valve upper cavity 2032 of the second electronic valve valve cavity are both communicated with the first channel 205; the second channel 206 is communicated with the electromagnetic valve lower cavity 2033 of the first electromagnetic valve valve cavity 2034; the third channel 207 is communicated with the electromagnetic valve lower cavity 2033 of the second electromagnetic valve valve cavity 2035; the electromagnetic valve lower cavity 2033 of the second electromagnetic valve valve cavity 2035 and the electromagnetic valve upper cavity 2032 of the third electromagnetic valve valve cavity 2036 are both communicated with the fourth channel 208; the fifth channel 209 is communicated with the electromagnetic valve lower cavity 2033 of the third electromagnetic valve valve cavity 2036.

[0044] In this embodiment, the first channel 205, the second channel 206, the third channel 207, and the fifth channel 209 can all communicate with an external pipeline through the openings at their respective ends. Fluids can flow between the first channel 205, the upper solenoid valve chamber 2032 of the solenoid valve in the first solenoid valve chamber 2034, and the upper solenoid valve chamber 2032 of the solenoid valve in the second solenoid valve chamber 2035. The second channel 206 can enable the fluid to flow between the lower solenoid valve chamber 2033 of the solenoid valve in the first solenoid valve chamber and the external pipeline. The third channel 207 can enable the fluid to flow between the lower solenoid valve chamber 2033 of the solenoid valve in the second solenoid valve chamber 2035 and the external pipeline. The fourth channel 208 can enable the fluid to flow between the lower solenoid valve chamber 2033 of the solenoid valve in the second solenoid valve chamber 2035 and the upper solenoid valve chamber 2032 of the solenoid valve in the third solenoid valve chamber 2036. The fifth channel 209 can enable the fluid to flow between the lower solenoid valve chamber 2033 of the solenoid valve in the third solenoid valve chamber 2036 and the external pipeline. This can facilitate achieving certain fluid control purposes by applying this fluid control system.

[0045] Among them, for convenience of processing, the fourth channel 208 can be set to penetrate the bottom of the valve chamber base body 202, and then a sealing plate is welded to the bottom plate surface of the valve chamber base body 202 to block the opening of the fourth flow channel located on the bottom plate surface of the valve chamber base body 202.

[0046] As an alternative solution, as Figures 2 to 4 shown, the openings of the first channel 205 and the second channel 206 are located on the first side of the valve chamber base body 202. The opening of the third channel 207 is located on the second side of the valve chamber base body 202 adjacent to the first side. The fourth channel 208 is located at the bottom of the valve chamber body base. The opening of the fifth channel 209 is located on the third side of the valve chamber base body 202 opposite to the second side. This structure can make the structure of the fluid control integrated device base compact.

[0047] Based on the above embodiment, further, as Figures 2 to 6 shown, among multiple valve chambers, including the electronic expansion valve chamber 204, the solenoid valve chamber includes an electronically controlled expansion valve port 2041, an upper electronically controlled expansion valve chamber 2042, and a lower electronically controlled expansion valve chamber 2043 that are sequentially connected. An annular replenishment groove 2044 is provided in the upper electronically controlled expansion valve chamber 2042, and the diameter of the annular replenishment groove 2044 is more than 1.1 times the diameter of the upper electronically controlled expansion valve chamber 2042.

[0048] In this embodiment, the upper electronically controlled expansion valve chamber 2042 and the lower electronically controlled expansion valve chamber 2043 are connected through the electronic expansion valve 6. Setting the annular replenishment groove 2044 in the upper electronically controlled expansion valve chamber 2042 can reduce fluid resistance.

[0049] As Figures 2 to 4As shown, on the basis of the above embodiments, further, a sixth channel, a seventh channel 212, and an eighth channel are further provided on the valve cavity base 202; the sixth channel is respectively connected to the annular replenishing groove 2044 and the liquid storage tank 3, one end of the seventh channel 212 is connected to the liquid storage tank 3, the other end opening of the seventh channel 212 is used for connecting to an external pipeline, and the eighth channel is connected to the lower cavity 2043 of the electronic expansion valve.

[0050] Specifically, the sixth channel may include a sixth upper channel 210 and a sixth lower channel 211. The sixth upper channel 210 is connected to the annular replenishing groove 2044 and one end of the sixth lower channel 211. The end opening of the sixth upper channel 210 may also be connected to an external pipeline. The other end of the sixth lower channel 211 passes through the connecting plate 201 to communicate with the inner cavity of the liquid storage tank 3; the eighth channel may include an eighth upper channel 213 and an eighth lower channel 214. The end opening of the eighth upper channel 213 may be connected to an external pipeline. The eighth upper channel 213 is connected to the eighth lower channel 214. The eighth lower channel 214 is provided on the connecting plate 201, and the eighth lower channel 214 is connected to the lower cavity 2043 of the electronic expansion valve 6 of the liquid storage tank 3.

[0051] Among them, for the convenience of processing, the eighth lower channel 214 may penetrate through the connecting plate 201 and is welded with a sealing plate on the bottom plate surface of the connecting plate 201 (that is, the surface facing the liquid storage tank 3) to block the opening of the eighth lower channel 214 located on the bottom plate surface of the connecting plate 201.

[0052] Multiple channels capable of being connected to an external pipeline, the channel includes a channel part and an end provided at one end of the channel part, the end is used for connecting to an external component, and the diameter of the end is more than 1.1 times the diameter of the channel part (for example: 1.1 times, 1.2 times, or 1.3 times, etc.), which is beneficial to reducing the flow resistance.

[0053] As Figure 7 shown, on the basis of the above embodiments, further, a check valve cavity 215 is further provided on the valve cavity base 202, and the check valve cavity is connected to the liquid storage tank 3.

[0054] In this embodiment, the check valve core assembly 4 can be installed in the check valve cavity 215. On the one hand, it realizes the control of the one-way flow of the fluid, and on the other hand, it can simplify the structure of the fluid control integrated device.

[0055] Among them, the check valve core assembly 4 may include a sealing mechanism 41, a valve core 42, a spring 43, a spring protection block 44, and a snap ring 45.

[0056] As Figure 8As shown, on the basis of the above embodiments, further, a liquid storage tank installation groove 11 is provided on the mounting base 1. An adjustable notch 12 is provided on one side of the liquid storage tank installation groove 11, and an arched reinforcing plate 13 is provided on the outer wall of the other side of the liquid storage tank installation groove 11.

[0057] In this embodiment, the width of the adjustable notch 12 can be adjusted by bolts, so as to adjust the clamping degree of the liquid storage tank installation groove 11 on the liquid storage tank 3. The number of the arched reinforcing plates 13 can be multiple, and the multiple arched reinforcing plates 13 are arranged at intervals along the length direction of the liquid storage tank installation groove 11. At least two installation points 14 are provided on the mounting base 1, and the arch structure can improve the reliability of the installation points 14. At least one support point 15 is provided on the mounting base 1.

[0058] As Figure 9 shown, on the basis of the above embodiments, the valve cavity base body 202 includes a first base body 2021 and a second base body 2022; both the first base body 2021 and the second base body 2022 are connected to the communication plate 201, and a heat insulation structure is provided between at least one of the first base body 2021 and the second base body 2022 and the communication plate 201. The first solenoid valve cavity 2034, the second solenoid valve cavity 2035, the third cavity, the first channel 205, the second channel 206, the third channel 207, the fourth channel 208, and the fifth channel 209 are arranged on the second base body 2022, and the electronic expansion valve cavity 204, the sixth channel, the seventh channel 212, and the eighth channel are arranged on the first base body 2021.

[0059] In this embodiment, the first base body 2021 and the second base body 2022 are independently arranged, and a heat insulation structure is provided between at least one of the first base body 2021 and the second base body 2022 and the communication plate 201. The heat insulation structure can reduce the heat exchange between at least one of them (the one with the heat insulation structure between the first base body 2021 and the second base body 2022 and the communication plate 201) and the communication plate 201, so as to reduce the indirect heat exchange between the first base body 2021 and the second base body 2022, and further reduce or even avoid the cross-heating of the fluid in the first base body 2021 and the fluid in the second base body 2022.

[0060] It should be noted that, as Figure 9 shown, the indirect heat exchange between the first base body 2021 and the second base body 2022 mainly passes through the communication plate 201; the first base body 2021 and the second base body 2022 are independently arranged, and a gap can be set between the first base body 2021 and the second base body 2022 to further reduce the heat exchange between the two.

[0061] Among them, a heat insulation structure is provided between at least one of the first base body 2021 and the second base body 2022 and the connecting plate 201. It can be understood that: a heat insulation structure is provided between the first base body 2021 and the connecting plate 201; or, a heat insulation structure is provided between the second base body 2022 and the connecting plate 201; or, a heat insulation structure is provided between the first base body 2021 and the connecting plate 201, and at the same time, a heat insulation structure is also provided between the second base body 2022 and the connecting plate 201.

[0062] Among them, as an optional solution, the first base body 2021 is in contact with the connecting plate 201, and a heat insulation structure is provided between the second base body 2022 and the connecting plate 201.

[0063] In this embodiment, the first base body 2021 and the connecting plate 201 can be regarded as a whole, and heat exchange can occur between the first base body 2021 and the connecting plate 201. The heat insulation structure is arranged between the second base body 2022 and the connecting plate 201, which can reduce or even avoid heat exchange between the second base body 2022 and the connecting plate 201, thereby reducing or even avoiding cross-heating of the fluids in the first base body 2021 and the second base body 2022. This setting can make the structure of the base simple and convenient for assembly.

[0064] The structural form of the heat insulation structure can be various. For example: a heat insulation pad can be provided between the bottom of the second base body 2022 and the connecting plate 201. One side of the heat insulation pad is fixedly connected to the connecting plate 201, and the other end of the heat insulation pad is connected to the bottom of the second base body 2022. The three can be connected together by bolts or screws.

[0065] As an optional solution, the heat insulation structure is an air heat insulation layer. It can be understood that the second base body 2022 is lifted relative to the connecting plate 201 so that there is a certain gap between the bottom of the second base body 2022 and the clamping plate, and this gap forms an air layer, avoiding setting other components to achieve heat insulation, further making the structure of the base simple.

[0066] Specifically, as Figure 9 shown, a support platform 2023 is provided on the connecting plate 201. The side of the support platform 2023 far from the connecting plate 201 is connected to the bottom of the second base body 2022 to form a gap between the second base body 2022 and the connecting plate 201, and the gap forms a layer heat insulation structure.

[0067] Among them, the height of the support platform 2023 can be set according to specific needs. The height of the support platform 2023 is also the height between the bottom surface of the second base body 2022 and the plate surface of the connecting plate 201 close to the second base body 2022 in the thickness direction of the connecting plate 201.

[0068] The connection between the support platform 2023 and the connecting plate 201 can be achieved by welding or by integral molding. Similarly, the connection between the support platform 2023 and the second base 2022 can be achieved by welding, thereby realizing the connection and fixation between the second base 2022 and the connecting plate 201.

[0069] As an alternative solution, as Figure 9 shown, the connecting plate 201 is further provided with connecting columns 2024. Bolt holes are provided on the connecting columns 2024. The second base 2022 is provided with a connecting plate 2025. Connecting holes are provided on the connecting plate 2025. The fastener 2026 is inserted into the connecting holes and the bolt holes.

[0070] In this embodiment, the second base 2022 and the connecting plate 201 are connected by bolts, thereby realizing the detachable connection between the second base 2022 and the connecting plate 201. On the one hand, the replacement of the second base 2022 can be realized, and on the other hand, the assembly of the second base 2022 and the connecting plate 201 is facilitated.

[0071] Among them, a plurality of connecting columns 2024 can be provided on the connecting plate 201. Bolt holes are provided on each connecting column 2024. Correspondingly, a plurality of connecting holes are provided on the second base 2022. The plurality of connecting holes and the plurality of bolt holes are arranged in one-to-one correspondence.

[0072] As an alternative solution, as Figure 9 shown, the support platform 2023 is provided with a pin 2027. A slot is provided at the bottom of the second base 2022. The pin 2027 is inserted into the slot.

[0073] In this embodiment, by inserting the pin 2027 into the slot, the second base 2022 can be limited, preventing the second base 2022 from rotating. Thus, the connection and fixation between the second base 2022 and the connecting plate 201 can be realized through one connecting hole and bolt hole, which is convenient for installation.

[0074] As Figure 9 shown, on the basis of the above embodiment, further, lugs are provided at the edge of the connecting plate 201. The support platform 2023 is connected to the lugs. In this embodiment, the provision of the lugs facilitates the connection of the connecting plate 201 to other structures.

[0075] Among them, the shape of the connecting plate 201 can be rectangular, oval or circular, etc.

[0076] As Figure 9 shown, on the basis of the above embodiment, further, the second base 2022 includes a first part, a second part and a third part. The first part and the third part are respectively connected to both sides of the second part. The first part, the second part and the third part form an L shape.
