Description

Technical Field

[0001] The present disclosure relates to a flow channel plate and a thermal management device. Background Art

[0002] At present, in order to protect the environment, the application of new energy vehicles is 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 will reduce the discharge efficiency and charging efficiency, thereby shortening the battery life. If the battery is in a high temperature state for a long time, it will cause an explosion accident. In addition, if the battery is in a low temperature state for a long time, it will cause meaningless power loss. Therefore, in electric vehicles, it is necessary to consider additional issues such as battery heat dissipation and motor heat dissipation, which makes the thermal management system of electric vehicles more complicated than that of traditional fuel vehicles, and there will be 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.

[0003] Usually, a thermal management integrated module is used to solve the above problems, and various thermal management elements and valves are arranged on the manifold plate for integration. Since a large number of components are integrated or installed on the manifold plate, the weight of the plate is large and the weight distribution is uneven, which may lead to problems such as unstable installation. Some known thermal management integrated modules are only installed from one direction and are not very stable. Other thermal management integrated modules use brackets to be installed on the vehicle, which increases the assembly process and increases the installation cost. Utility Model Content

[0030] Reference below Figures 1 to 5 Various embodiments 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 are described in detail. The thermal management device according to the present disclosure is used to distribute a heat transfer fluid, and the heat transfer fluid may be, for example, the refrigerant described below. The thermal management device may be installed on a vehicle body of a vehicle. For example, the vehicle body includes a frame, and the thermal management device may be installed on the frame. The thermal management device according to the present disclosure may be used in new energy vehicles, such as electric vehicles, hybrid vehicles, and the like. The thermal management device includes a refrigerant circuit for the circulation of a refrigerant and a coolant circuit for the circulation of a coolant. The refrigerant may be, for example, Freon or propane, and the coolant may be, for example, a mixed liquid of water and ethylene glycol.

[0031] like Figure 1 and 3As shown, the thermal management device may include a flow channel plate 1, a first valve 100 and a second valve 200. The first valve 100 may be a multi-way valve, which is at least partially integrated on the flow channel plate 1 to improve the integration level and reduce the material cost and assembly cost. The second valve 200 may be a one-way valve, which is arranged to be fluidically connected to a valve port of the first valve 100. The flow channel plate 1 may also be called a manifold plate, on which a plurality of flow channels are arranged. For example, the valve cavity of the first valve 100 may be at least partially formed in the flow channel plate 1, so that at least part of the valve body structure of the valve may be omitted, while reducing the assembly process. For example, the second valve 200 may be inserted into the flow channel on the flow channel plate 1.

[0032] For example, the flow channel plate 1 may be a refrigerant plate, on one side of which a thermal management element in a refrigerant circuit of a thermal management device is mounted. Various thermal management elements may be mounted on the flow channel plate 1, such as a drying bottle 120, a heat exchanger 121, expansion valves 122 and 123, etc. The expansion valves 122 and 123 are, for example, electronic expansion valves. The specific positions of the various thermal management elements on the flow channel plate 1 depend on the situation and are not limited to Figure 1 and 3 In other examples, the flow channel plate 1 may be a cooling liquid plate, and the heat transfer fluid flowing in the flow channel thereof may be a cooling liquid.

[0033] In addition, the flow channel plate 1 may be provided with various openings, such as Figure 1 The openings 23, 24, 25, 26 shown in FIG. Figure 3 The openings 25, 26, 27, 28, etc. are shown in FIG. These openings are in fluid communication with the thermal management element through a conduit, or are directly connected to an inlet or outlet of the thermal management element.

[0034] like Figures 1 to 4 As shown, the flow channel plate 1 includes a main body portion 2 extending along a first direction D1 and having a plurality of flow channels disposed thereon. The first direction D1 may also be referred to as the length direction of the flow channel plate 1 . Figure 1 and 2 Also shown is a second direction D2 which is transverse to (eg perpendicular to) the first direction D1, and the second direction D2 may also be referred to as the width direction of the flow channel plate 1. The flow channel plate 1 has an extension plane extending along the first direction D1 and the second direction D2.

[0035] For example, the flow channel plate 1 further includes a transverse portion 3 extending along the second direction D2, which is disposed at one end of the main body portion 2. Therefore, the flow channel plate 1 generally has an "L" shape. The first valve 100 and the second valve 200 described above can be disposed on the transverse portion 3, for example, the valve cavity of the first valve 100 can be integrated on the transverse portion 3. In addition, the flow channel on the flow channel plate 1 can extend along the first direction D1 and the second direction D2, with a compact structure and convenient processing.

[0036] like Figures 1 to 4 As shown, the flow channel plate 1 includes a first fixing portion 5 and a second fixing portion 6, and the first fixing portion 5 and the second fixing portion 6 are arranged at both ends of the main part 2 along the first direction D1. For example, the first fixing portion 5 and the second fixing portion 6 are protrusions protruding from the main part 2 of the flow channel plate 1. The flow channel plate 1 also includes an intermediate fixing portion 7, which is arranged in the middle area of ​​the main part 2. The intermediate fixing portion 7 is located between the first fixing portion 5 and the second fixing portion 6 in the first direction D1, for example, it is arranged in the central area of ​​the flow channel plate 1. For example, the intermediate fixing portion 7 is a protrusion protruding from the main part 2 of the flow channel plate 1. The above arrangement makes it possible to provide a three-point fixation for the flow channel plate 1.

[0037] For example, the first fixing portion 5 and the second fixing portion 6 are arranged at the first edge of the flow channel plate 1, and the intermediate fixing portion 7 is arranged at the second edge of the flow channel plate 1 opposite to the first edge. When the flow channel plate is installed in a vehicle, the first edge can be called the lower edge, and the second edge can be called the upper edge. The above arrangement enables the first fixing portion 5, the second fixing portion 6 and the intermediate fixing portion 7 to form a triangular fixation, thereby improving the installation stability, and no additional bracket is required for auxiliary fixation.

[0038] The above mentioned Figure 1 The openings 23, 24, 25, 26 and Figure 3 The openings 25, 26 in the flow channel plate can be arranged at the second edge, and their opening direction is, for example, perpendicular to the extension plane of the flow channel plate 1. In this way, the joint position of the opening with the external pipeline or the thermal management element is moved to the edge of the flow channel plate, thereby improving the compactness of the flow channel plate.

[0039] The above mentioned Figure 3 The openings 27 , 28 in the flow channel plate 1 may be arranged on the side surfaces of the flow channel plate 1 .

[0040] For example, the first fixing portion 5, the second fixing portion 6 and the intermediate fixing portion 7 form an integral component with the flow channel plate 1, that is, they are integrally molded, which improves the integration and increases the structural strength.

[0041] For example, the first fixing portion 5 has a first hole 8, the second fixing portion 6 has a second hole 9, and the central axis A1 of the first hole 8 and / or the central axis A2 of the second hole 9 are perpendicular to the first direction D1. Figures 1 to 5 In some examples, the central axis A1 of the first hole 8 and / or the central axis A2 of the second hole 9 may be parallel to the second direction D2, and it is also possible that they form an angle with the second direction D2.

[0042] For example, Figure 5As shown, when viewed along the first direction D1, the central axis A1 of the first hole 8 forms an angle with the central axis A2 of the second hole 9. In other words, the central axis A1 of the first hole 8 is not parallel to the central axis A2 of the second hole 9. This arrangement allows the flow channel plate to meet different installation environments.

[0043] For example, the middle fixing portion 7 includes a third hole 10, and the central axis A3 of the third hole 10 is perpendicular to the extension plane of the flow channel plate 1. The first fixing portion 5, the second fixing portion 6 and the middle fixing portion 7 improve the installation stability and the fixing strength by fixing the flow channel plate in two different directions.

[0044] For example, the first fixing portion 5 includes a first bottom plate 11, which is connected to the main body portion 2 and is transverse to the extension plane of the flow channel plate 1. Figure 2 , 4 and 5, the first bottom plate 11 extends obliquely from the first edge of the flow channel plate 1 away from the thermal management element on the flow channel plate, that is, toward Figure 5 The first hole 8 is formed in the first bottom plate 11, and the central axis A1 of the first hole 8 is perpendicular to the first bottom plate 11. In other words, the central axis A1 of the first hole 8 deviates from the extension plane of the flow channel plate 1, that is, the first bottom plate 11 forms an angle with the extension plane, such as an obtuse angle. The second fixing portion 6 includes a second bottom plate 12, which is connected to the main body 2 and is transverse to the extension plane of the flow channel plate 1. For example, see Figure 2 , 4 and 5, the second bottom plate 12 extends obliquely from the first edge of the flow channel plate 1 away from the thermal management element on the flow channel plate, that is, toward Figure 5 The second hole 9 is formed in the second bottom plate 12, and the central axis A2 of the second hole 9 is perpendicular to the second bottom plate 12. In other words, the central axis A2 of the second hole 9 deviates from the extension plane of the flow channel plate 1, that is, the second bottom plate 12 forms an angle with the extension plane, such as an obtuse angle. One of the first bottom plate 11 and the second bottom plate 12 is arranged to face Figure 5 It is also possible to extend obliquely to the lower left of the center. Figure 5 The first hole 8 and / or the second hole 9 are inclined to the lower left of the middle part, so that the central axis of the first hole 8 and / or the second hole 9 deviates as much as possible to the outside relative to the second direction D2, thereby facilitating the installation of fasteners (such as nuts). The above arrangement can prevent the thermal management element installed on the flow channel plate from interfering with the installation of the fasteners at the second fixing portion 6, especially preventing the joint between the thermal management element and the flow channel plate from interfering with the fasteners, especially as Figure 3 The joints at the interfaces 27 and 28 of the flow channel plate 1 shown in FIG.

[0045] like Figure 5As shown, looking along the first direction D1, the first bottom plate 11 and the second bottom plate 12 are staggered. The "staggered arrangement" described herein refers to a non-overlapping arrangement.

[0046] For example, Figure 5 As shown, when viewed along the first direction D1, the first bottom plate 11 and the second bottom plate 12 form an angle. In other examples, when viewed along the first direction D1, the first bottom plate 11 and the second bottom plate 12 are arranged in parallel. This arrangement may depend on the frame on which the flow channel plate 1 is installed.

[0047] like Figure 2 and 4 As shown, a first reinforcing rib 13 is provided between the main body 2 of the flow channel plate 1 and the first main board 11; and / or a second reinforcing rib 14 is provided between the main body 2 and the second bottom board 12. The first reinforcing rib 13 and the second reinforcing rib 14 may be a plate-like or block-like structure extending transversely to the extension plane of the flow channel plate 1. The number of the first reinforcing rib 13 and the second reinforcing rib 14 may be one or more. By providing the reinforcing ribs, the strength of the flow channel plate can be increased and the installation stability can be improved.

[0048] like Figure 3 and 4 As shown, the flow channel plate 1 also includes a connection portion 15 extending from the main body 2 to the outside, which is used to fix and connect the drying bottle 120. Channels 16 and 17 are formed in the connection portion 15, and the channels are configured to connect the flow channel on the main body 2 with the drying bottle 120 fluid. For example, the extension direction of the channels 16 and 17 is perpendicular to the extension plane of the flow channel plate 1. For example, part of the connection portion 15 has the form of a pipeline. For example, the connection portion 15 is integrally formed with the main body 2 of the flow channel plate 1.

[0049] In some examples of the thermal management device disclosed herein, the thermal management device includes a drying bottle 120 and a flow channel plate 1 as described above, wherein the drying bottle 120 is mounted on the flow channel plate 1 and is in fluid communication with the flow channel plate 1, such as Figure 1 and 3 shown.

[0050] For example, the thermal management device further includes a heat exchanger 121, and the main body 2 of the flow channel plate 1 extends along the first direction D1. Figure 3 In the example shown, along the first direction D1, the second fixing portion 6 of the flow channel plate 1 is located between the first fixing portion 5 of the flow channel plate 1 and the drying bottle 120, the heat exchanger 121 is close to the first fixing portion 5, and the drying bottle 120 is close to the second fixing portion 6. In other words, the heat exchanger 121 with a larger mass in the thermal management device is closer to the first fixing portion 5, and the drying bottle 120 is closer to the second fixing portion 6. Figure 1 Compared to the embodiment shown, Figure 3Such an arrangement can shorten the distance between the first fixing part 5 and the second fixing part 6, and make the center of the component with larger mass close to the first fixing point and the second fixing point respectively, so that the weight distribution is balanced and the overall strength of the flow channel plate and the thermal management device is improved to a certain extent.

[0051] As described above, the flow channel plate of the present disclosure has a three-point fixing part and uses different fixing directions, so it has high installation stability. In addition, the flow channel plate of the present disclosure uses a fixing part adapted to the installation environment, does not require the assistance of a bracket, simplifies the assembly process, and reduces the installation cost. It should be noted that the thermal management device of the present disclosure has the various advantages of the flow channel plate described above.

[0052] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of disclosure to achieve the purpose of this disclosure.
