Furthermore, under complex operating conditions, conflicts between thermal performance and flow resistance performance can easily arise. In addition, some heat exchanger runners have complex structural designs, are difficult to manufacture, and have high costs. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0036] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0037] Please refer to Figures 1-3 This embodiment provides a flow channel fin 100, which includes a fin body 110 and at least one partition 120 connected to the fin body 110. The partition 120 divides the fin body 110 into at least two flow channel segments 101.

[0038] Each flow channel segment 101 is equipped with multiple flow guide channels 111, which are staggered and extend in the same direction.

[0039] Therefore, by configuring the above-described structure, by configuring the partition 120 on the fin body 110, after the flow channel fin 100 is installed into the heat exchange cavity 201, at least two flow channel segments 101 separated by the partition 120 can be partitioned and guided in the heat exchange cavity 201 and connected to each other, and their guiding directions can be different. That is, the two flow channel segments 101 can form an angled flow channel 202 in the heat exchange cavity 201.

[0040] Based on this, each flow channel section 101 is provided with multiple flow channels 111 for guiding flow and heat exchange. As the coolant flows along each flow channel 111, heat exchange can be carried out, thereby improving its heat exchange efficiency through this arrangement.

[0041] Furthermore, it should be noted that since the partition 120 is configured on the flow channel fins 100, it can form the flow channel 202 based on the aforementioned two flow channel segments 101 while the flow channel fins 100 are installed to the heat exchange chamber 201. Therefore, when adjusting or forming the flow channel 202, the shape, structure, quantity, and position of the partition 120 on the flow channel fins 100 can be adjusted accordingly. This reduces the cost of structural design and manufacturing of the heat exchange flow channel plate 200, provides high assembly flexibility, has a wide range of applications, and has low overall structural processing and assembly difficulty. It can reduce its usage cost while taking into account product strength, flow resistance, and thermal performance.

[0042] It should be noted that this arrangement is based on setting a partition 120 to form two flow channel sections 101, namely the first flow channel section 102 and the second flow channel section 103; in other embodiments of this utility model, the number and position of the partition 120 can be adjusted to form more flow channel sections 101 in the heat exchange cavity 201.

[0043] The following description uses the application of the flow channel fin 100 to the heat exchange flow channel plate 200 as an example. Specifically, the heat exchange flow channel plate 200 includes a flow channel plate shell 210, an inlet pipe joint 220 and an outlet pipe joint 230, as well as the aforementioned flow channel fin 100.

[0044] The flow channel plate shell 210 is equipped with a heat exchange chamber 201. It should be noted that the flow channel plate shell 210 includes an upper plate 211 and a lower plate 212. The upper plate 211 and the lower plate 212 can be made by stamping or other methods. They can be combined to form the heat exchange chamber 201. The water inlet pipe joint 220 and the water outlet pipe joint 230 are connected to the upper plate 211 or the lower plate 212.

[0045] Moreover, the flow channel fins 100 are disposed in the heat exchange cavity 201, and the two flow channel sections 101 are formed together in the heat exchange cavity 201 to form a bent flow channel 202.

[0046] Both the inlet pipe connector 220 and the outlet pipe connector 230 are connected to the flow channel plate housing 210 and are respectively connected to the two ends of the flow channel 202.

[0047] Please refer to Figures 1-5 The working principle of the heat exchanger plate 200 is as follows:

[0048] First, the heat exchange flow channel plate 200 is used in the thermal management assembly. Its function is to remove heat through the coolant. The heat exchange flow channel plate 200 includes a flow channel plate shell 210, flow channel fins 100, a water inlet pipe joint 220, and a water outlet pipe joint 230. The flow channel plate shell 210 is equipped with a heat exchange chamber 201. The flow channel fins 100 are disposed in the heat exchange chamber 201 and form a bent flow channel 202 in the heat exchange chamber 201. The water inlet pipe joint 220 and the water outlet pipe joint 230 are both connected to the flow channel plate shell 210 and are respectively connected to the two ends of the flow channel 202.

[0049] The heat exchanger plate 200 employs flow channel fins 100 arranged within the heat exchange chamber 201. These fins 100 not only perform heat exchange but also form the flow channels 202 for heat exchange. Therefore, compared to the existing method of forming the flow channels 202 by stamping onto a plate, this heat exchanger plate 200 forms the flow channels 202 internally based on the structure of the flow channel fins 100. Thus, during the formation of the flow channels 202, different types of flow channels 202 can be formed based on improvements to the flow channel fins 100. This simplifies the overall structure, making the design simpler, providing greater assembly flexibility, and broad applicability. Furthermore, the overall structure is easy to process and assemble, reducing usage costs while maintaining product strength, flow resistance, and thermal performance.

[0050] Therefore, the heat exchange flow channel plate 200 can adjust the internal flow channel 202 pattern according to actual usage requirements. Thus, when applied to the same thermal management component or when its application scenario is adjusted, it can form a flow channel 202 pattern that meets usage requirements by improving its flow channel fins 100 without structurally modifying its flow channel plate shell 210, thereby reducing the overall structural cost.

[0051] In addition, since the heat exchange flow channel plate 200 can adjust the pattern of its internal flow channel 202 according to actual usage requirements, the bent flow channel 202 formed can meet the usage requirements, thereby improving its heat exchange efficiency and its compatibility.

[0052] It should be noted that, in this embodiment, based on the above content, the flow channel 202 in the heat exchange flow channel plate 200 is a bent flow channel 202. Based on this, this embodiment is described with the formed flow channel 202 being a U-shaped flow channel 202 as an example. However, in other embodiments of this utility model, the flow channel 202 can also be set to an L-shape or other shapes.

[0053] It should also be noted that during the use of the heat exchange flow channel plate 200, the heat exchange medium, taking coolant as an example, is introduced into the heat exchange chamber 201 through the inlet pipe joint 220, and then flows along the flow channel 202 in the heat exchange chamber 201 to exchange heat, and is then discharged through the outlet pipe joint 230; when it flows in the heat exchange chamber 201, it flows along the guiding direction of the flow channel 202 in the heat exchange chamber 201.

[0054] The flow channel fin 100 includes a fin body 110 and at least one partition 120 connected to the fin body 110. The partition 120 divides the fin body 110 into at least two flow channel segments 101. Each flow channel segment 101 is provided with multiple flow guide channels 111, which are staggered and extend in the same direction. The flow channel fin 100 is used in the heat exchange flow channel plate 200 of a thermal management component. It has a simple structural design, high assembly flexibility, wide applicability, and low overall structural processing and assembly difficulty. It can reduce its operating cost while taking into account product strength, flow resistance, and thermal performance.

[0055] Based on the above structure, in order to enable the two flow channel segments 101 separated by the partition member 120 in the heat exchange cavity 201 to be connected, and in this embodiment, the flow channel 202 is described as having a U-shaped shape, that is, the two flow channel segments 101 are parallel and the flow directions of the two flow channel segments 101 are opposite. Therefore, in order to enable the two flow channel segments 101 to be connected, each flow channel segment 101 is provided with a clearance portion 112 at its end along its flow direction, which is spaced apart from the inner wall of the heat exchange cavity 201. The clearance portion 112 is used to form a flow guiding area 104 in the heat exchange cavity 201, and the flow guiding area 104 is used to connect the two flow channel segments 101.

[0056] In addition, in this embodiment, to increase the flow guiding method according to actual needs, besides the aforementioned method of forming the flow guiding area 104 in the heat exchange cavity 201, the flow channel fins 100 are also equipped with flow guiding sections. The flow guiding sections cross the partition 120 and connect the two flow channel sections 101. That is, according to actual usage needs, flow guiding sections can be added in the opposite areas of the two flow channel sections 101, so that the flowing coolant can flow along the flow channel 202 from the aforementioned flow guiding area 104, or after flowing to one flow channel section 101, it can be guided to the other flow channel section 101 through the flow guiding section, thereby improving the flexibility and efficiency of heat exchange.

[0057] In addition, when configuring the partition 120, the flow channel fin 100 includes a plurality of partitions 120, which are arranged in parallel and spaced apart; one partition 120 divides the fin body 110 into two flow channel segments 101, and the remaining partitions 120 are disposed within the flow channel segments 101 and divide the corresponding flow channel segments 101 into two parallel sub-flow segments 105. Furthermore, in this embodiment, as described above, the flow directions of the flow channel 202 regions corresponding to the two flow channel segments 101 are opposite. Therefore, when multiple partition members 120 are configured, they can be arranged parallel and spaced apart. One partition member 120 is used to separate two flow channel segments 101 within the heat exchange chamber 201, while the remaining partition members 120 are disposed within the flow channel segments 101, dividing the corresponding flow channel segments 101 into two parallel sub-flow segments 105. The flow directions of the two sub-flow segments 105 are consistent with the flow direction of the flow channel segment 101. Therefore, through this arrangement, two flow channel segments 101 can be formed by one partition member, and the flow channel segments 101 can be segmented or diverted by the remaining partition members 120, thereby improving the flexibility of the heat exchange flow channel plate 200.

[0058] It should be noted that, as Figure 4 and Figure 5 As shown, in this embodiment, a configuration of three partitions 120 is adopted, namely a first partition 121, a second partition 122, and a third partition 123. The first partition 121 is used to separate the first flow channel section 102 and the second flow channel section 103. The second partition 122 is located within the first flow channel section 102 and divides the first flow channel section 102 into a first sub-flow section 106 and a second sub-flow section 107. The third partition 123 is located within the second flow channel section 103 and divides the second flow channel section 103 into a third sub-flow section 108 and a fourth sub-flow section 109.

[0059] Further, please refer to Figures 1-8 As can be seen from the above, the heat exchanger plate 200 simplifies its structure and reduces its design and manufacturing costs by configuring partitions 120 on the flow channel fins 100. Therefore, when configuring partitions 120, they can be integrally formed with the flow channel fins 100 (e.g., Figure 1 As shown), it can also be manufactured separately from the flow channel fins 100 and then fixedly connected (as shown). Figure 7 and Figure 8 (As shown).

[0060] Specifically, the partition 120 includes a partition plate 124 integrally formed with the flow channel fin 100. Furthermore, as described above, since the flow channel fin 100 is equipped with multiple flow guide channels 111, the partition plate 124 can protrude from the plate body of the flow channel fin 100 while being integrally formed with it, forming an independent boss structure. It can also function as a guide channel 111, thereby separating the flow guide channels 111 belonging to the two flow channel segments 101. This arrangement allows the flow channel fin 100 to be manufactured in an integral molding manner, thereby improving manufacturing efficiency and reducing manufacturing costs.

[0061] Unlike the method described above where the partition 120 and the flow channel fin 100 are integrally molded, please refer to... Figures 1-8 The partition 120 can also be a stop pin 125 separately manufactured from the flow channel fins 100. Specifically, the partition 120 includes a stop pin 125, which is fixedly connected to the flow channel fins 100 and the flow channel plate housing 210, such as by welding, threaded connection, riveting, or bonding, with welding being the preferred connection method. By setting the stop pin 125 at the corresponding position on the flow channel fins 100, and welding the stop pin 125 to the flow channel fins 100 and the flow channel plate housing 210, the stability and sealing performance can be improved, preventing leakage problems.

[0062] Unlike the method described above where the partition 120 and the flow channel fin 100 are integrally molded, please refer to... Figures 1-8 The partition 120 can also be a baffle tube 126 separately manufactured from the flow channel fins 100. Specifically, the partition 120 includes a hollow baffle tube 126, which is fixedly connected to the flow channel fins 100 and the flow channel plate shell 210, such as by high-frequency welding, threaded connection, riveting, or bonding, with high-frequency welding being the preferred connection method. Moreover, when configuring the baffle tube 126, the baffle tube 126 has a hollow structure, resulting in a lighter overall product weight. Furthermore, the end of the baffle tube 126 is equipped with an end cap 127, which can meet the current demand for lightweight new energy products. On the other hand, the baffle tube 126 can be made of composite plate material by high-frequency welding, with its own composite layer, which greatly reduces the need for solder coating in the process, making it more practical.

[0063] It should be noted that when configuring the aforementioned stop pins 125 and stop tubes 126, the guide channels 111 on the flow channel fins 100 can be ordinary staggered tooth structures. Therefore, the structures of the stop pins 125 and stop tubes 126 can be configured according to the structural parameters of the flow channel fins 100, so that their structural dimensions can be adapted to the structure of the flow channel fins 100, thereby enabling standard and diverse layout settings, and providing diverse flow channel 202 style selections, thereby improving its flexibility and compatibility, and reducing the research and development cycle and development costs.

[0064] It should be noted that the flow channel fins 100 provided in this embodiment can also be applied to other products that require heat exchangers, such as plate heat exchangers and tube-and-belt heat exchangers.

[0065] Based on the above, please refer to Figures 1-8 This embodiment also provides a thermal management component, which includes the heat exchange flow channel plate 200 described above.

[0066] This thermal management component can be applied to one or more of the following structures: power battery packs, motor cooling systems, electronic device cooling, and energy storage systems. By adopting the aforementioned heat exchanger plate 200, the overall structure of this thermal management component can be simplified, making its structural design simpler, providing higher assembly flexibility, and having a wide range of applications. Furthermore, the overall structure is easy to process and assemble, reducing usage costs while balancing product strength, flow resistance, and thermal performance. Moreover, different types of flow channels 202 can be formed based on improvements to the flow channel fins 100. In this way, when applied to the same thermal management component or when adjusting its application scenario, without structural modifications to the flow channel plate housing 210, the flow channel fins 100 can be modified to create a flow channel 202 style that meets the usage requirements, thereby reducing overall structural costs.

[0067] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
