Detailed Embodiments

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0033] In the description and claims of the present utility model, terms such as "first", "second", etc. are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present utility model can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0034] It should be understood that "some embodiments" mentioned throughout the specification means that specific features, structures, or characteristics related to the embodiments are included in at least one embodiment of the present utility model. Therefore, "in some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.

[0035] The following specifically introduces a flow channel plate, a thermal management device, and a vehicle provided by the present utility model by listing specific embodiments.

[0036] Figure 1 and Figure 2 show schematic diagrams of two perspectives of the flow channel plate in the embodiments of the present utility model. Referring to Figure 1 and Figure 2 , a stamping groove is provided on the plate body of a flow channel plate provided by the present utility model, and the stamping groove is used to form a flow channel for a circulating medium.

[0037] Specifically, the plate body of the flow channel plate is used to form the flow channel plate. Each flow channel plate is usually composed of two plate bodies of the flow channel plate. For example, Figure 1 and Figure 2 the plate body 1 and the plate body 2 in are both plate bodies of the flow channel plate, and the plate body 1 and the plate body 2 are cooperatively connected to form a complete flow channel plate. A stamping groove is provided on the plate body of the flow channel plate. For example, Figure 1 and Figure 2 the stamping groove 10 in is the stamping groove on the plate body 1, and the stamping groove 20 is the stamping groove on the plate body 2. The stamping groove is used to form a flow channel for a circulating medium, and the medium includes but is not limited to coolant. It can be understood that the stamping groove is formed by processing the plate body of the flow channel plate through a stamping process. The stamping process is a forming method that uses equipment such as a press and a mold to apply external forces to plates, strips, tubes, profiles, etc., so that they undergo plastic deformation or separation, thereby obtaining workpieces with the required shapes and sizes. The plate body of the flow channel plate adopts the stamping process, and the corresponding stamping groove can be directly processed on the plate body of the flow channel plate through one stamping.

[0038] In the prior art, it is necessary to perform machining on the runner plate body to machine the required runner structure. This machining method takes a long time, resulting in low machining efficiency. At the same time, a large amount of material is wasted during machining, resulting in a high production cost of the runner plate body. In contrast, the runner plate body of the present utility model directly punches a punching groove through a stamping process, and the punching groove forms a runner for circulating the medium. Compared with the prior art, it can effectively shorten the machining time of the runner on the runner plate body, improve the machining efficiency, and the runner plate body of the present utility model no longer needs to adopt the machining method to machine the runner, which can effectively reduce the waste of materials and reasonably control the machining cost.

[0039] Figure 3 shows a sectional view of the runner part of the runner plate in the embodiment of the present utility model. Optionally, referring to Figure 3 , the punching groove is an arc groove.

[0040] Specifically, as Figure 3 shown, the punching groove 10 is the punching groove on the plate body 1, and the punching groove 20 is the punching groove on the plate body 2. Both punching grooves are arc grooves. The curvature radii of the two arc grooves can be the same or different. If the curvature radii of the two arc grooves are the same, the two arc grooves can cooperate with each other to form a runner 3 with a circular or elliptical cross-section, as Figure 3 shows the schematic manner in which the cross-section of the runner 3 is circular. If the curvature radii of the two arc grooves are different, the two arc grooves can cooperate with each other to form a runner 3 with a larger upper diameter and a smaller lower diameter or a smaller upper diameter and a larger lower diameter. Of course, in a preferred embodiment, the curvature radii of the two arc grooves are still set to be the same to facilitate the positioning and cooperation of the two arc grooves, and the formed circular or elliptical cross-section runner 3 helps to reduce the frictional resistance of the medium flowing in the runner 3 and is not easily blocked, which can ensure the smooth flow of the medium, so that the runner plate has a stronger flow-through capacity.

[0041] Optionally, the opening size of the punching groove is 10 mm to 20 mm.

[0042] Specifically, to ensure the medium flow-through capacity of the runner, the opening size of the punching groove on the runner plate body can be set to 10 mm to 20 mm to avoid blocking the runner. Correspondingly, in actual applications, if the flow rate of the medium to be circulated by the runner plate is large, the opening size of the punching groove can be set to 20 mm to ensure the smooth flow of the medium; if the flow rate of the medium to be circulated by the runner plate is small, the opening size of the punching groove can be set to 10 mm to ensure the strength of the runner plate.

[0043] Optionally, referring to Figure 1 and Figure 2 , the punching groove is at least two.

[0044] Specifically, at least two stamping grooves are provided on the flow channel plate body, such as Figure 1 and Figure 2 The schematic diagrams of two stamping grooves on each flow channel plate body are shown respectively, wherein two stamping grooves at opposite positions cooperate with each other to form a complete flow channel, that is, Figure 1 and Figure 2 The schematic diagram can form two flow channels. Of course, if there are multiple stamping grooves on the flow channel plate body, then every two relatively positioned stamping grooves in the multiple stamping grooves cooperate with each other to eventually form multiple flow channels. The specific number of flow channels is set according to the actual needs of the connected pipelines, which is not limited in this embodiment. It should be noted that the multiple flow channels can be arranged at intervals to avoid mixing of the media caused by the mutual communication of the flow channels. In addition, the multiple flow channels are arranged in a winding manner on the flow channel plate, and the layout shapes of the flow channels can be the same or different. They are set according to the actual positions of the connected pipelines, which is not limited in this embodiment.

[0045] Optionally, refer to Figure 1 and Figure 2 A connecting seat is also stamped on the plate body, and the connecting seat has a hollow inner cavity, which is connected to the stamping groove.

[0046] Specifically, when the punching groove is punched on the flow channel plate body, the connecting seat can also be punched at the same time, such as Figure 1 A connection seat 11 is stamped on the middle plate body 1. Figure 2 A connecting seat 21 is stamped on the middle plate body 2. The connecting seat 11 on the plate body 1 is arranged on the side of the plate body 1 facing away from the plate body 2. The connecting seat 11 has a hollow inner cavity, and the hollow inner cavity passes through the connecting seat 11 so that the connecting seat 11 is connected to the cavity of other components. The hollow inner cavity of the connecting seat 11 is connected to the stamping groove 10 on the plate body 1. In some embodiments, the connecting seat 11 can be directly arranged on the stamping groove 10 so that the hollow inner cavity of the connecting seat 11 remains connected to the stamping groove 10. In other embodiments, the connecting seat 11 can be set at a position deviating from the stamping groove 10, and an additional connecting groove is subsequently opened between the connecting seat 11 and the stamping groove 10 to connect the hollow inner cavity of the connecting seat 11 with the stamping groove 10. Similarly, the connecting seat 21 on the plate body 2 is arranged on the side of the plate body 2 away from the plate body 1. The connecting seat 21 has a hollow inner cavity, and the hollow inner cavity of the connecting seat 21 is connected to the stamping groove 20. The connecting seat 21 can be directly set on the stamping groove 20, or it can be set at a position deviating from the stamping groove 20. The connection principle is similar to the connection principle between the connecting seat 11 and the stamping groove 10 on the plate body 1, and will not be repeated here.

[0047] Reference Figure 1 and Figure 2, the present utility model further provides a runner plate, which includes a first plate body and a second plate body. The first plate body and / or the second plate body is the runner plate body described in any of the foregoing embodiments. The first plate body is welded to the second plate body, and the stamping grooves of the first plate body and / or the second plate body form a runner for the flowing medium.

[0048] Specifically, as Figure 1 and Figure 2 shown, the runner plate includes a first plate body 1 and a second plate body 2. In some embodiments, the first plate body 1 can adopt the runner plate body of any of the foregoing embodiments, and the first plate body 2 adopts the runner plate body in the prior art. In some other embodiments, the second plate body 2 can adopt the runner plate body of any of the foregoing embodiments, and the first plate body 1 adopts the runner plate body in the prior art. In still some other embodiments, both the first plate body 1 and the second plate body 2 can adopt the runner plate body of any of the foregoing embodiments. The first plate body 1 is welded to the second plate body 2. After welding, the stamping grooves of the first plate body and / or the stamping grooves of the second plate body will form a runner for the flowing medium. Compared with the prior art, the runner plate of the present utility model can effectively shorten its processing time, improve processing efficiency, and the runner plate of the present utility model no longer needs to adopt the machining method, which can effectively reduce the waste of materials and reasonably control the processing cost. In addition, when obtaining the runner plate with the required specification dimensions by stamping and welding two plate bodies, it will not cause an increase in the mass density of the runner plate, thereby helping to control the overall weight of the runner plate.

[0049] Optionally, referring to Figure 1 and Figure 2 , the stamping grooves are provided on both the first plate body and the second plate body, and the opening size of the stamping groove of the first plate body is the same as the opening size of the stamping groove of the second plate body.

[0050] Specifically, the stamping groove of the first plate body is as shown by the first stamping groove 10 in Figure 1 and Figure 2 , and the stamping groove of the second plate body is as shown by the second stamping groove 20 in Figure 1 and Figure 2 . It should be noted that the first stamping groove 10 and the second stamping groove 20 are only for the sake of facilitating the understanding of the present utility model in terms of name, and there is no essential difference from the stamping grooves in the foregoing embodiments. When the opening size of the first stamping groove 10 is the same as the opening size of the second stamping groove 20, there will be no dislocation at the mating part of the first stamping groove 10 and the second stamping groove 20. The inner wall of the runner 3 formed after mating is a smooth transition structure, which is not easy to retain the medium and is not easy to cause blockage of the runner 3, thereby ensuring the smooth flow of the medium.

[0051] Optionally, the thickness of the first plate body 1 and the second plate body 2 is 2 mm to 4 mm.

[0052] Specifically, to meet the pressure resistance requirements of the first plate body 1 and the second plate body 2 and minimize pressure loss, the thickness of the first plate body 1 and the second plate body 2 can be set to 2 mm to 4 mm, avoiding cracks, fractures, etc. during the stamping process due to the first plate body 1 and the second plate body 2 being too thin, which would cause waste of resources. In practical applications, if the flow rate of the medium to be circulated through the flow channel plate is large, the thickness of the first plate body 1 and the second plate body 2 can be set to 4 mm to ensure the reliability of the flow channel plate; if the flow rate of the medium to be circulated through the flow channel plate is small, the thickness of the first plate body 1 and the second plate body 2 can be set to 2 mm to control the weight and processing cost of the flow channel plate.

[0053] Optionally, referring to Figure 1 and Figure 2 , a first mounting point 12 is further provided on the first plate body 1, and a second mounting point 22 is further provided on the second plate body 2, and the first mounting point 12 and the second mounting point 22 are coaxially arranged.

[0054] Specifically, as shown in Figure 1 and Figure 2 , the first mounting point 12 and the second mounting point 22 are coaxially arranged. The first mounting point 12 and the second mounting point 22 can play a pre-positioning role during the welding process of the first plate body 1 and the second plate body 2, improving the welding accuracy of the first plate body 1 and the second plate body 2. The first mounting point 12 and the second mounting point 22 can also be used to mount the welded flow channel plate on external components, such as on the vehicle body. In a preferred embodiment, the first mounting point 12 and the second mounting point 22 are provided as through holes with internal threads to facilitate the fastener to pass through the first mounting point 12 and the second mounting point 22 to directly install and fix the flow channel plate.
