[0002] Currently, in order to protect the environment, new energy vehicles are becoming more and more common. In electric vehicles, which are new energy vehicles, a large amount of heat is generated when the electric drive mechanism is powered, resulting in an increase in resistance, which reduces the discharge efficiency and charging efficiency, thus shortening the service life of the battery. The battery being in a high temperature state for a long time can lead to explosion accidents. In addition, the battery being in a low temperature state for a long time causes meaningless power consumption. Therefore, issues such as battery heat dissipation and motor heat dissipation need to be additionally considered in electric vehicles, which makes the thermal management system of electric vehicles more complex than that of traditional fuel vehicles and there are also more pipelines. However, the overall layout space of the vehicle is limited, which brings troubles and challenges to the layout of the thermal management system of new energy vehicles.

[0033] The following references Figures 1 to 8Describe in detail each embodiment of the thermal management device for a vehicle and the flow channel plate of the thermal management device according to the embodiments of the present disclosure. The thermal management device according to the present disclosure is used to distribute a heat transfer fluid, which can be, for example, a refrigerant as described below. The thermal management device can be installed on the vehicle body of a vehicle. For example, the vehicle body includes a frame, and the thermal management device can be installed on the frame. The thermal management device according to the present disclosure can be used for new energy vehicles, such as electric vehicles, hybrid vehicles, etc. The thermal management device includes a refrigerant circuit for refrigerant circulation and a coolant circuit for coolant circulation. The refrigerant is, for example, freon or propane, and the coolant is, for example, a mixed liquid of water and ethylene glycol.

[0034] As Figure 1 and 6 shown, the thermal management device can include a flow channel plate, a multi-way valve 100, and a check valve 200. The flow channel plate can also be called a manifold plate, on which a plurality of flow channels are provided, and the refrigerant can flow in the flow channels. By connecting the plurality of flow channels with the multi-way valve 100 and the check valve 200, different thermal management modes can be achieved. The multi-way valve 100 can be a five-way valve or a four-way valve, which is installed on the flow channel plate to improve the integration degree, reduce the material cost and the assembly cost. The check valve 200 can be arranged to be in fluid communication with one valve port of the multi-way valve 100. For example, as Figure 2 and 7 shown, the valve cavity 10 of the multi-way valve 100 can be at least partially formed within the flow channel plate, the valve cover of the multi-way valve 100 is installed on the flow channel plate to enclose the valve cavity 10, and the valve core of the multi-way valve 100 is connected to the valve cover and arranged within the valve cavity for realizing the fluid communication of at least two valve ports. This setting can save at least part of the valve body structure and reduce the assembly process at the same time. For example, the check valve 200 can be inserted into the flow channel on the flow channel plate. For example, the check valve 200 is arranged in the flow channel in fluid communication with one valve port of the multi-way valve 100 and does not allow the heat transfer fluid to flow from this valve port into the valve cavity 10.

[0035] For example, the flow channel plate can be a refrigerant plate. In other examples, the flow channel plate can be a coolant plate, and the heat transfer fluid flowing in its flow channels can be a coolant.

[0036] As Figure 1 and 2 and Figure 6 and 7 shown, the thermal management device further includes a fluid element 120, which is installed on the flow channel plate and is in fluid communication with the flow channel plate; in a specific embodiment, the flow channel plate includes a main body portion 1, a first connection portion 21, a second connection portion 22, and an installation portion 30. For example, the installation portion 30 can be a block.

[0037] As Figure 1 and2 and Figure 6 and 7 As shown, the main body portion 1 has a first portion 2 extending along a first direction D1 and a second portion 3 extending along a second direction D2 transverse to the first direction D1. The first direction D1 may also be referred to as the length direction of the main body portion 1. The second direction D2 may be perpendicular to the first direction D1 and thus may also be referred to as the width direction of the main body portion 1. The main body portion 1 has an extended plane formed by the extension of the first direction D1 and the second direction D2.

[0038] For example, the second portion 3 is provided at one end of the first portion 2. Thus, the main body portion 1 generally has an "L" shape. The first valve 100 and the second valve 200 described above may be provided on the second portion 3. For example, the valve cavity 10 of the first valve 100 may be located in the second portion, for example, formed on the second portion 3. In addition, the flow channels on the main body portion 1 may extend along the first direction D1 and the second direction D2. Therefore, the flow channel structure is simple and the flow resistance is small, making the structure of the flow channel plate compact and convenient for processing.

[0039] Combined with Figure 5 and 8 , the first connection portion 21 has a first connection channel 26, and the second connection portion 22 has a second connection channel 27. As Figure 3 and 7 shown, the mounting portion 30 has a first internal channel 33 and a second internal channel 34. The first connection portion 21 is respectively connected to the main body portion 1 and the mounting portion 30 so that the first connection channel 26 is in fluid communication with the main body portion 1 and the first internal channel 33. The second connection portion 22 is respectively connected to the main body portion 1 and the mounting portion 30 so that the second connection channel 27 is in fluid communication with the main body portion 1 and the second internal channel 34. Specifically, the first or second connection portion fluidly connects the flow channel on the main body portion 1 with the corresponding internal channel.

[0040] As Figure 3 shown, the first connection portion 21 is respectively connected to the first portion 2 and the mounting portion 30 so that the first connection channel 26 is in fluid communication with the first portion 2 and the first internal channel 33. The second connection portion 22 is respectively connected to the second portion 3 and the mounting portion 30 so that the second connection channel 27 is in fluid communication with the second portion 3 and the second internal channel 34. The fluid communication with the first portion 2 or the second portion 3 described here refers to fluid communication with the flow channels provided on the first portion 2 or the second portion 3. As Figure 5 shown, the first connection channel 26 may be in fluid communication with other flow channels on the first portion 2 of the main body portion 1. The second connection channel 27 may be in fluid communication with one valve port of the multi-way valve 100.

[0041] In Figures 1 to 5In the example, the first connecting portion 21 extends generally in a direction opposite to the first direction D1 from the first part 2 and then generally in the second direction D2. The second connecting portion 22 extends generally in the first direction D1 from the second part 3, for example, from the middle edge of the second part 3, and then generally in the second direction D2.

[0042] As Figure 7 shown, the first connecting portion 21 is respectively connected to the first part 2 and the mounting portion 30 so that the first connecting channel 26 fluidly communicates the first part 2 and the first internal channel 33. The second connecting portion 22 is respectively connected to the first part 2 and the mounting portion 30 so that the second connecting channel 27 fluidly communicates the first part 2 and the second internal channel 34. The fluid communication with the first part 2 described herein means fluid communication with the flow channels provided on the first part 2. As Figure 8 shown, the first connecting channel 26 can be fluidly communicated with other flow channels on the first part 2 of the main body portion 1, and the second connecting channel 27 can be fluidly communicated with a valve port of the multi-way valve 100.

[0043] In Figures 6 to 8 the example, the first connecting portion 21 extends generally in the first direction D1 from the first part 2, for example, from one end of the first part 2, and then generally in the second direction D2. The second connecting portion 22 extends generally in the first direction D1 from the first part 2, for example, from one edge of the first part 2, and then generally in the second direction D2. For example, the second connecting portion 22 extends obliquely upward towards Figure 7 the right side in

[0044] Specifically, the first part 2 has a first edge 41 and a second edge 42 transverse to the first edge 41, and the first edge 41 and the second edge 42 define a corner 43 of the first part 2; the first connecting portion 21 extends in a direction away from the first part 2 from the first edge 41, and the second connecting portion 22 extends in a direction away from the first part 2 from the second edge 42.

[0045] In Figures 1 to 5 the example, the mounting portion 30 can be located near the second part 3. In Figures 6 to 8 the example, the mounting portion 30 can be located at the end of the first part 2 away from the second part.

[0046] For example, the fluid component 120 may include a drying bottle. The drying bottle is disposed on one side of the flow channel plate through the mounting portion 30. One end of the drying bottle is engaged and communicated with the mounting portion 30. In addition, other fluid components are also disposed on one side of the flow channel plate, such as a heat exchanger 121, expansion valves 122 and 123, etc. The heat exchanger 121 may be a chiller, which includes a heat exchange portion connected to the refrigerant circuit and a heat exchange portion connected to the coolant circuit. The expansion valves 122 and 123 are, for example, electronic expansion valves for throttling and expanding the fluid flowing through them. In an embodiment not shown, a compressor may also be provided on the main body portion 1 as a fluid component. In Figures 1 to 5 example, the fluid component 120 is disposed adjacent to the second portion 3, making the device more compact. In Figures 6 to 8 example, the fluid component 120 is disposed away from the second portion and away from the relatively heavy heat exchanger 121, making the mass distribution of the heat management device more uniform and improving the overall strength of the flow channel plate to a certain extent. The specific positions of various fluid components on the flow channel plate depend on the circumstances and are not limited to Figure 1 and 6 shown.

[0047] For example, the mounting portion 30 has a mounting surface 35 for mounting the fluid component 120. The first internal channel 33 and the second internal channel 34 respectively extend to the mounting surface 35. The inlet and outlet of the fluid component 120 are respectively engaged with the mounting surface 35 and are then in fluid communication with the first internal channel 33 and the second internal channel 34.

[0048] For example, the mounting surface 35 is parallel to the extension plane of the main body portion 1. This enables the fluid component 120 to be mounted on one side of the main body portion 1, especially parallel to the main body portion, thereby making the structure more compact and having a higher integration degree.

[0049] For example, both the first connection portion 21 and the second connection portion 22 are located in the extension plane of the main body portion 1. This enables the flow channel plate not to have additional protruding portions, distributes the weight as evenly as possible, further improves the integration degree, and makes the flow channel plate stronger.

[0050] For example, the first connection portion 21 and the second connection portion 22 are spatially separated from each other through the hollow portion 37 on the flow channel plate, as shown in Figure 2 and 3 and Figure 7 and 8 shown. For example, the first connection portion 21, the second connection portion 22, the main body portion 1, and the mounting portion 30 jointly enclose the hollow portion 37, as shown in Figure 7 shown. For example, the first connection portion 21, the second connection portion 22, the first portion 2, the second portion 3, and the mounting portion 30 jointly enclose the hollow portion 37, as shown in Figure 3As shown. In this way, the first connecting portion 21, the second connecting portion 22, and the mounting portion 30 form a "ji"-shaped structure, which enhances the strength of the "L"-shaped main body portion, and thus increases the structure of the flow channel plate. In addition, the hollowed-out portion reduces the weight of the flow channel plate.

[0051] In Figure 3 In the illustrated embodiment, the "ji"-shaped structure is located at the corner of the "L"-shaped main body portion, thereby further enhancing the strength of the "L"-shaped main body portion.

[0052] For example, the first connecting portion 21, the second connecting portion 22, the mounting portion 30, and the main body portion 1 form an integral component. In other words, the first connecting portion 21, the second connecting portion 22, the mounting portion 30, and the main body portion 1 are integrally formed. This makes the processing simpler and the structure more compact.

[0053] As Figure 4 and 5 and Figure 8 As shown, the main body portion 1 includes a plate body 23 and a plurality of cover plates 24. An installation cavity 10 of the multi-way valve 100 described above is provided on one side of the plate body 23, and a plurality of grooves 25 are provided on the other side. For example, the grooves 25 open in the direction away from the mounting surface 35 of the mounting portion 30. A part of the flow channel is the internal channel of the plate body 23, and another part of the flow channel is defined by the grooves 25 and the corresponding cover plates 24. The cover plates 24 cover the grooves 25 and are sealingly connected to the grooves 25. For example, the internal channel and the grooves 25 are integrally formed with the plate body 23. The first connecting channel 26 includes a groove 25 provided on the first connecting portion 21 and a cover plate 24 for covering the groove, and the second connecting channel 27 includes a groove 25 provided on the second connecting portion 22 and a cover plate 24 for covering the groove. In other examples, one of the first connecting channel 26 and the second connecting channel 27 may be the internal channel of the plate body 23.

[0054] For example, as Figure 2 and 5 and Figure 7 and 8 As shown, the valve cavity 10 of the multi-way valve 100 included in the thermal management device is at least partially formed on the main body portion 1 and is in fluid communication with the second connecting channel 27. As Figure 2 and 7As shown, the multi-way valve 100 includes a plurality of valve ports, such as a first valve port 11, a second valve port 12, a third valve port 13, a fourth valve port 14, and a fifth valve port 15. The fifth valve port 15 is the valve cavity inlet fluidly connected to the outlet of the compressor. The fourth valve port 14 is fluidly connected to the second connection passage 27. The first valve port 11, the second valve port 12, the third valve port 13, and the fourth valve port 14 are fluidly connected to corresponding flow channels. The valve core passage of the multi-way valve 100 is used to be fluidly connected to two of the first valve port 11, the second valve port 12, the third valve port 13, the fourth valve port 14, and the fifth valve port 15 respectively to assist in realizing different thermal management modes. For example, the multi-way valve 100 can have two operating conditions. In the first operating condition, the first valve port 11 is fluidly connected to the fifth valve port 15, the third valve port 13 is fluidly connected to the fourth valve port 14, and the second valve port 12 is blocked by the valve core. In the second operating condition, the fourth valve port 14 is fluidly connected to the fifth valve port 15, the first valve port 11 is fluidly connected to the second valve port 12, and the third valve port 13 is blocked by the valve core. Of course, other types of operating conditions are also possible.

[0055] As described above, the thermal management device of the present disclosure installs fluid components, such as a dryer bottle, through a "Z"-shaped mounting structure, making the flow channel plate stronger, the structure more compact, and having a higher integration degree. In addition, the thermal management device of the present disclosure is easy to process, convenient to assemble, and has a low cost.

[0056] The above-disclosed technical features are not limited to the combinations with other disclosed features. Those skilled in the art can also make other combinations among the technical features according to the disclosure purpose, subject to achieving the purpose of the present disclosure.
