Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a flow channel plate, a thermal management system, and a vehicle. Background Technology

[0002] Vehicle thermal management systems typically use piping to connect various cooling components, resulting in significant weight, high cost, and a large footprint. With continuous improvements in thermal management systems, flow channels can be used to provide mounting points for other components. The internal structure of the flow channel can integrate flow channels, enabling the arrangement and distribution of flow.

[0003] To achieve the one-way shut-off function of specific flow channels within the flow channel plate, a check valve is usually installed on the flow channel. The check valve is located outside the flow channel, which takes up a lot of space, and the connection between the check valve and the flow channel is prone to media leakage, resulting in insufficient reliability. Utility Model Content

[0004] The purpose of this utility model is to solve the aforementioned technical problems by providing a flow channel plate, a thermal management system, and a vehicle, thereby realizing a unidirectional shut-off structure within the medium flow channel of the flow channel plate. This unidirectional shut-off structure occupies less space, is less prone to leakage, and has high reliability. To achieve the above objective, the technical solution of this utility model is as follows:

[0005] A flow channel plate includes a plate body assembly, wherein a medium flow channel is provided within the plate body assembly, and a one-way shut-off structure is provided within the medium flow channel.

[0006] The unidirectional cut-off structure includes a first support portion, a second support portion, a cut-off element, and a flow portion. The first support portion and the second support portion are spaced apart on the inner wall of the flow portion along the medium conveying direction to form an inner cavity for accommodating the cut-off element. The inner cavity communicates with the medium flow channel. A gap is provided between the cut-off element and the inner wall of the flow portion. A first through-hole is provided on the first support portion. The cut-off element moves along the medium conveying direction to open or close the first through-hole.

[0007] Specifically, a through hole is provided between the outer periphery of the second support portion and the inner wall of the flow portion.

[0008] Specifically, the inner circumference of the second support portion is provided with a second through opening, the second through opening and the first through opening are arranged along the same axis, and the stop member moves against the second through opening.

[0009] Specifically, both the first through-hole and the second through-hole are provided with support surfaces in their circumferential directions, and the support surfaces are in close contact with the circumferential direction of the stop member.

[0010] Specifically, the outer periphery of the second support is connected to the inner wall of the flow section through a plurality of first guides. The first guides are arranged along the conveying direction of the medium and move against the stop member.

[0011] Specifically, the inner wall of the cavity is provided with a plurality of second guide portions, which are arranged along the conveying direction of the medium and move against the stop member.

[0029] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0030] In one embodiment, a flow channel plate is provided, including a plate assembly 1 and a parts group. The plate assembly 1 has a plurality of medium flow channels 11. The flow channel plate is used in a vehicle's thermal management system, where a circulating medium circulates through the medium flow channels 11 to cool and dissipate heat from components in the thermal management system. For some medium flow channels 11, one-way valves are required; for example, water needs to be added to the motor circuit, and a one-way valve is installed in the motor circuit. However, the one-way valve is additionally installed on the flow channel plate, occupying space and hindering the installation and arrangement of the flow channel plate. Furthermore, as an assembly component of the flow channel plate, the one-way valve is prone to assembly leakage, reducing the reliability of the flow channel plate. This embodiment optimizes the flow channel plate by avoiding the use of traditional one-way valves, by providing a one-way shut-off structure 2 within the medium flow channels 11, as described in detail below.

[0031] like Figures 1-3As shown, the unidirectional cut-off structure 2 includes a first support portion 21, a second support portion 22, a cut-off element 23, and a flow portion 25. The first support portion 21 and the second support portion 22 are spaced apart on the inner wall of the flow portion 25 along the medium conveying direction to form an inner cavity 24 for accommodating the cut-off element 23. The inner cavity 24 communicates with the medium flow channel 11. A gap is provided between the cut-off element 23 and the inner wall of the flow portion 25. A first through-hole 31 is provided on the first support portion 21. The cut-off element 23 moves along the medium conveying direction to open or close the first through-hole 31 to achieve unidirectional flow of the medium in the medium flow channel 11. A through hole 33 is provided between the outer periphery of the second support portion 22 and the inner wall of the flow portion 25. The first support portion 21, the second support portion 22, and the flow portion 25 together form the inner cavity 24. The flow portion 25 can be disposed alone in the medium flow channel 11 or can be used as part of the medium flow channel 11, with the inner wall of the flow portion 25 being the inner wall of part of the medium flow channel 11.

[0032] When there is flowing medium in the medium flow channel 11, the medium can enter the inner cavity 24 through the first through port 31 of the first support part 21. Due to the pressure of the medium transport, the medium can push the stop member 23 away from the first support part 21 and open the first through port 31. The stop member 23 moves to abut against the second support part 22. There is a gap between the stop member 23 and the inner wall of the flow part 25. The medium can be sent out from the inner cavity 24 through the gap and the through hole 33, thereby realizing the transport of the medium along the positive direction of the medium flow channel 11. However, the medium cannot be transported in the opposite direction of the medium flow channel 11. It can be understood that when the medium enters the inner cavity 24 through the through hole 33, the stop member 23 moves to abut against the first support part 21 and closes the first through port 31. Therefore, the unidirectional stop structure 2 can realize the unidirectional flow of the medium.

[0033] By setting a one-way cut-off structure 2 inside the medium flow channel 11, the one-way cut-off structure 2 is built into the medium flow channel 11 without occupying the external space of the flow channel plate. At the same time, when the medium is transported in the one-way cut-off structure 2, there is no problem of medium leakage to the outside of the flow channel plate, which improves the overall reliability of the flow channel plate and reduces the complexity and cost of flow channel plate assembly.

[0034] In one embodiment, a second through-hole 32 is provided on the inner periphery of the second support portion 22. The second through-hole 32 and the first through-hole 31 are arranged along the same axis, and the stop member 23 moves against the second through-hole 32.

[0035] The inner cavity 24 can be a hollow cylindrical structure. The first through port 31 and the second through port 32 are arranged along the same axis. The stop member 23 can be a sphere to ensure that the stop member 23 can be smoothly positioned at the first through port 31 or the second through port 32 when moving in the inner cavity 24. The stop member 23 cooperates with the first through port 31 to close the inner cavity 24, that is, to close the medium flow channel 11. The stop member 23 cooperates with the second through port 32 to limit the movement of the stop member 23, thereby preventing the stop member 23 from running out of the inner cavity 24 along the medium flow channel 11 and being unable to open and close the medium flow channel 11 again. 1. The cooperation between the stop member 23 and the second through port 32 does not affect the transport of the medium in the inner cavity 24. There is a gap between the stop member 23 and the inner wall of the flow section 25. There is a through hole 33 between the outer periphery of the second support part 22 and the inner wall of the flow section 25. When the stop member 23 opens the first through port 31, the medium can still flow out of the inner cavity 24 from the gap and the through hole 33. The stop member 23 moves from the first through port 31 to the second through port 32 along the transport direction of the medium. The axial movement path of the stop member 23 in the inner cavity 24 is relatively short. The stop member 23 can maintain stability when positioned at the first through port 31 or the second through port 32.

[0036] In other embodiments, the second support portion 22 may not have the second through-hole 32. Without affecting the positioning of the second support portion 22 and the stop member 23, the through hole 33 can smoothly transport the medium, and the second support portion 22 will not affect the transport of the medium. The flow area of ​​the through hole 33 can meet the function of transporting the medium by the unidirectional stop structure 2.

[0037] However, the second support 22 is provided with a second through port 32. When the medium flows in the medium channel 11 in the opposite direction, the medium can enter the inner cavity 24 in large quantities and quickly through the through hole 33 and the second through port 32, thereby generating sufficient pressure on the inner cavity 24 and forcing the stop member 23 to directly close the first through port 31. If the medium only enters the inner cavity 24 through the through hole 33, and the flow area of ​​the through hole 33 is small, the initial pressure of the medium entering the inner cavity 24 is small. Before the stop member 23 closes the first through port 31, a large amount of medium has already flowed back from the first through port 31. The response efficiency of the unidirectional stop structure 2 is low. Therefore, the second support 22 is provided with a second through port 32 so that when the medium flows in the opposite direction, the stop member 23 moves and closes the first through port 31 in time, further improving the reliability of the unidirectional stop structure 2.

[0038] In one embodiment, both the first through-hole 31 and the second through-hole 32 are provided with support surfaces 34 in the circumferential direction, and the support surfaces 34 are in circumferential contact with the stop member 23.

[0039] The supporting surface 34 can be configured as an annular surface, so that it corresponds and fits against the spherical surface of the stop element 23. The circumferential contact between the supporting surface 34 and the stop element 23 serves two purposes: firstly, it positions the stop element 23, ensuring a stable fit between the stop element 23 and the first through port 31, preventing the stop element 23 from shifting within the inner cavity 24 due to medium pressure; secondly, it provides a sealing function, acting as a one-way valve by being close to the first through port 31, thus closing the medium flow channel 11. Similarly, when the stop element 23 is stably fitted with the second through port 32, it also serves to position the stop element 23.

[0040] In one embodiment, the outer periphery of the second support portion 22 is connected to the inner wall of the flow portion 25 by a plurality of first guide portions 41, the first guide portions 41 being arranged along the conveying direction of the medium and moving against the stop member 23.

[0041] The first guide portion 41 is evenly arranged on the outer periphery of the second support portion 22, serving to connect the second support portion 22 with the inner wall of the flow portion 25, keeping the second support portion 22 in a suspended state, that is, allowing a through hole 33 to be formed between the second support portion 22 and the inner wall of the flow portion 25, without obstructing the transport of the medium; a plurality of first guide portions 41 are arranged around the same circumference, and the diameter of the circumference formed by the plurality of first guide portions 41 is adapted to the diameter of the stop member 23, which can guide the stop member 23 to move smoothly to the second through opening 32, and prevent the stop member 23 from being misaligned when moving in the inner cavity 24.

[0042] In one embodiment, the inner wall of the inner cavity 24 is provided with a plurality of second guide portions 42, which are arranged along the conveying direction of the medium and move against the stop member 23.

[0043] Among them, a plurality of second guide portions 42 are evenly arranged around the same circumference, and the ends of the second guide portions 42 extend to the first support portion 21. The circumference diameter formed by the plurality of second guide portions 42 is adapted to the diameter of the stop member 23. The second guide portions 42 can guide the stop member 23 to move smoothly to the first through opening 31.

[0044] The first guide portion 41 and the second guide portion 42 can be connected or spaced apart, without affecting the function of the guide stop 23 moving within the inner cavity 24. When the movement stroke of the stop 23 within the inner cavity 24 is long, the first guide portion 41 and the second guide portion 42 are connected to form the entire guide portion, ensuring that the stop 23 moves through the guide portion throughout the entire inner cavity 24. The gap between the stop 23 and the inner wall of the inner cavity 24 is evenly distributed, allowing the medium to stably push the stop 23 when entering the gap, thus improving the stability of the stop 23's movement.

[0045] In one embodiment, the plate assembly 1 includes a plurality of substrates 12 stacked together, with a medium flow channel 11 formed between adjacent substrates 12.

[0046] Specifically, the plurality of substrates 12 include a first substrate, a second substrate, and a third substrate. The first substrate, the second substrate, and the third substrate are sequentially welded and fixed by a hot-melt process. The first substrate and the second substrate are connected to form a portion of the dielectric flow channel 11, and the second substrate and the third substrate are connected to form another portion of the dielectric flow channel 11. It can be understood that the unidirectional cut-off structure 2 is disposed in the dielectric flow channel 11. The dielectric flow channel 11 can be formed by splicing adjacent substrates 12, and the unidirectional cut-off structure 2 can also be formed by splicing adjacent substrates 12.

[0047] In one embodiment, a heat insulation cavity 13 is provided in the substrate 12 at intervals, and the heat insulation cavity 13 communicates with the outside of the substrate 12.

[0048] Specifically, the heat insulation cavity 13 is disposed within the second substrate. The heat insulation cavity 13 is used to separate the two parts of the medium flow channel 11 to avoid heat leakage problems. For example, it prevents the low-temperature water in the battery circuit and the high-temperature water in the motor circuit from leaking heat to each other, thereby achieving the effect of energy saving. In this embodiment, the heat insulation cavity 13 opens from the edge of the substrate 12, making it easy to manufacture from a mold. At the same time, a part of the medium flow channel 11 can be formed at the top of the heat insulation cavity 13, and another part of the medium flow channel 11 can be formed at the bottom of the heat insulation cavity 13. Most of the medium flow channels 11 on the flow channel plate flow through the top or bottom of the heat insulation cavity 13, achieving a better heat insulation effect.

[0049] In one embodiment, a thermal management system is provided, including the flow channel plate and thermal management device described in the above embodiments, such as... Figure 4 As shown, the thermal management device includes a battery, a motor, a plate heat exchanger 61, a radiator 62, and a kettle 63. The flow channel plate is connected to the thermal management device through a component assembly, thereby enabling the medium in the kettle 63 to circulate between the flow channel plate and the thermal management device. The medium in the kettle 63 can be liquid water, achieving the cooling effect of the thermal management device.

[0050] The flow channel plate includes a plate assembly 1 and a component group. The component group includes a battery circuit water outlet 51, a battery water pump inlet 52, a heater inlet 53, a radiator inlet 54, a motor circuit water outlet 55, a radiator outlet 56, an integrated three-way valve inlet 57, and a battery water pump replenishment inlet 58. The component group is connected to the medium flow channel 11, such as... Figure 4 As shown, a nine-way valve is formed inside the flow channel plate, and the various ports of the nine-way valve are connected through the medium flow channel 11.

[0051] Specifically, the medium's transport path in the battery circuit is as follows: the medium circulates between the battery water pump, the battery, the battery circuit outlet 51, the fourth interface, the third interface, the plate heat exchanger 61, the fifth interface, the sixth interface, and the battery water pump inlet 52, achieving the cooling effect of the medium in the battery circuit. When the battery circuit needs to be replenished with medium, the medium in the kettle 63 is connected to the battery water pump inlet 52 through the battery water pump replenishment port 58. When the battery water pump is working, the medium can enter the battery water pump from the kettle 63, thereby replenishing the battery circuit with medium.

[0052] The medium's transport path in the motor circuit is as follows: the medium enters from the warm air inlet 53, passes through the eighth interface, the seventh interface, and the radiator inlet 54; specifically, the medium passes through the radiator 62 from the radiator inlet 54 and then enters the radiator outlet 56; or the medium passes through the eighth interface, the ninth interface, and the radiator outlet 56, and finally passes through the motor circuit outlet 55, the first interface, and the second interface, and is discharged from the integrated three-way valve inlet 57. A motor water pump is installed on the radiator outlet 56. A one-way shut-off structure 2 is installed in the medium flow channel 11 between the battery water pump replenishment port 58 and the radiator outlet 56 to effectively prevent the medium from flowing back from the radiator outlet 56 to the battery water pump inlet 52. When the motor circuit needs to be replenished with medium, the medium in the kettle 63 is connected to the radiator outlet 56. When the motor water pump is working, the medium can enter the radiator outlet 56 from the kettle 63, thereby replenishing the motor circuit with medium. When the medium in kettle 63 is being added, it can simultaneously replenish the medium to both the motor circuit and the battery circuit.
