[0031] Now, various exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps set forth in these embodiments, numerical expressions and values do not limit the scope of the present application.

[0032] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way serves as a limitation to the present application or its application or use.

[0033] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods and devices should be regarded as part of the specification.

[0034] In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0035] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] First, the flexible heat exchange plate 100 according to the embodiments of the present application will be specifically described below with reference to the accompanying drawings.

[0037] As Figures 1 to 4As shown, the flexible heat exchange plate 100 according to an embodiment of the present application includes a first metal layer 10 and a second metal layer 30.

[0038] Specifically, a first polymer layer 20 is provided on a first side of the first metal layer 10, a first side of the second metal layer 30 is connected to a second side of the first metal layer 10, and a second polymer layer 40 is provided on a second side of the second metal layer 30; at least one of the second side of the first metal layer 10 and the first side of the second metal layer 30 is provided with a groove, and an inner wall surface of the groove and the other define a heat exchange flow channel 50.

[0039] In other words, as Figures 1 to 4 shown, the flexible heat exchange plate 100 according to an embodiment of the present application mainly includes a first metal layer 10 and a second metal layer 30, and the first metal layer 10 and the second metal layer 30 are arranged in a laminated manner and fixedly connected together. At least one of a side of the first metal layer 10 close to the second metal layer 30 (i.e., the second side of the first metal layer 10) and a side of the second metal layer 30 close to the first metal layer 10 (i.e., the first side of the second metal layer 30) is provided with a groove, and the required heat exchange flow channel 50 can be defined by the inner wall surface of the groove and the surface of the adjacent metal layer.

[0040] Further, a first polymer layer 20 is provided on a side of the first metal layer 10 facing away from the second metal layer 30 (i.e., the first side of the first metal layer 10), so as to effectively improve the structural strength and flexibility of the flexible heat exchange plate 100. When the heat exchange plate needs to be bent or adapted to a complex installation space, the first polymer layer 20 can effectively disperse stress and prevent the first metal layer 10 from being damaged due to excessive bending.

[0041] Correspondingly, a second polymer layer 40 is provided on a side of the second metal layer 30 facing away from the first metal layer 10 (i.e., the second side of the second metal layer 30), so as to effectively improve the structural strength and flexibility of the flexible heat exchange plate 100. When the heat exchange plate needs to be bent or adapted to a complex installation space, the second polymer layer 40 can effectively disperse stress and prevent the second metal layer 30 from being damaged due to excessive bending.

[0042] It should be noted that the first metal layer 10, the second metal layer 30, the first polymer layer 20, and the second polymer layer 40 are all flexible layers, which will not be elaborated in this embodiment.

[0043] Thus, for the flexible heat exchange plate 100 provided according to this embodiment, by providing the first metal layer 10 and the second metal layer 30, the heat conduction ability of the flexible heat exchange plate 100 can be effectively improved, thereby effectively improving the heat exchange performance of the flexible heat exchange plate 100; at the same time, by providing the first polymer layer 20 and the second polymer layer 40, the structural strength and flexibility of the flexible heat exchange plate 100 can be ensured, so that the flexible heat exchange plate 100 can meet different usage requirements.

[0044] In some alternative examples of the application, the materials of the first metal layer 10 and the second metal layer 30 may be a copper layer, an aluminum layer, or a stainless steel layer.

[0045] According to an embodiment of the present application, a first groove is provided on the second side of the first metal layer 10, and an inner wall surface of the first groove and a first side of the second metal layer 30 define a first heat exchange channel; and / or, a second groove is provided on the first side of the second metal layer 30, and an inner wall surface of the second groove and a second side of the first metal layer 10 define a second heat exchange channel.

[0046] That is to say, the specific structures for forming the heat exchange channel 50 include the following situations:

[0047] Situation 1: As shown in Figure 2 , a first groove is provided on the second side of the first metal layer 10, and an inner wall surface of the first groove and a first side of the second metal layer 30 define a first heat exchange channel. The inner wall surface of the first groove and the surface of the first side of the second metal layer 30 corresponding to the first groove form the inner wall surface of the first heat exchange channel.

[0048] In this case, it is beneficial for the first heat exchange channel to be close to the first side of the flexible heat exchange plate 100, which is beneficial to improving the heat exchange effect on the first side of the flexible heat exchange plate 100.

[0049] Situation 2: A second groove is provided on the first side of the second metal layer 30, and an inner wall surface of the second groove and a second side of the first metal layer 10 define a second heat exchange channel. The inner wall surface of the second groove and the surface of the second side of the first metal layer 10 corresponding to the second groove form the inner wall surface of the second heat exchange channel.

[0050] In this case, it is beneficial for the second heat exchange channel to be close to the second side of the flexible heat exchange plate 100, which is beneficial to improving the heat exchange effect on the second side of the flexible heat exchange plate 100.

[0051] Situation 3: A first groove is provided on the second side of the first metal layer 10, and an inner wall surface of the first groove and a first side of the second metal layer 30 define a first heat exchange channel. A second groove is provided on the first side of the second metal layer 30, and an inner wall surface of the second groove and a second side of the first metal layer 10 define a second heat exchange channel.

[0052] In this case, the first heat exchange channel is close to the first side of the flexible heat exchange plate 100, and the second heat exchange channel is close to the second side of the flexible heat exchange plate 100, so that the flexible heat exchange plate 100 has heat exchange areas with different heat exchange performances, effectively improving the applicability of the flexible heat exchange plate 100.

[0053] In some specific embodiments of the present application, the first heat exchange channel and the second heat exchange channel are connected.

[0054] In other words, the first heat exchange channel and the second heat exchange channel can be used independently or in series. When the first heat exchange channel and the second heat exchange channel are used independently, the flexible heat exchange plate 100 is provided with two sets of liquid through holes. One set of liquid through holes is in communication with the first heat exchange channel, and the other set of liquid through holes is in communication with the second heat exchange channel. Specifically, the first liquid through hole of the first set of liquid through holes is in communication with the first end of the first heat exchange channel, and the second liquid through hole of the first set of liquid through holes is in communication with the second end of the first heat exchange channel; the first liquid through hole of the second set of liquid through holes is in communication with the first end of the second heat exchange channel, and the second liquid through hole of the second set of liquid through holes is in communication with the second end of the second heat exchange channel. Thus, the heat exchange liquid in the heat exchange channel 50 and the second heat exchange channel can be independently driven by different micro pumps.

[0055] When the first heat exchange channel and the second heat exchange channel are used in series, the first end of the first heat exchange channel is in communication with the first end of the second heat exchange channel. For example, a part of one end of the first tank body corresponds to a part of one end of the second tank body, so that the first end of the first heat exchange channel is in communication with the first end of the second heat exchange channel. In this case, the flexible heat exchange plate 100 is provided with a set of liquid through holes. The first liquid through hole of this set of liquid through holes is in communication with the second end of the first heat exchange channel, and the second liquid through hole of this set of liquid through holes is in communication with the second end of the second heat exchange channel. Thus, a single micro pump can drive the heat exchange liquid in the first heat exchange channel and the second heat exchange channel to flow together.

[0056] According to an embodiment of the present application, a first tank body is provided on the second side of the first metal layer 10, and a second tank body is provided on the first side of the second metal layer 30. The inner wall surface of the first tank body and the inner wall surface of the second tank body define the heat exchange channel 50.

[0057] Specifically, a first tank body is provided on the second side of the first metal layer 10. The shape of the first tank body can be a serpentine structure. A second tank body is provided on the first side of the second metal layer 30. In the thickness direction of the flexible heat exchange plate 100, the projection of the first tank body on the second metal layer 30 coincides with the second tank body, so that the inner surface of the first tank body and the inner wall surface of the second tank body define the heat exchange channel 50, that is, the inner wall surface of the first tank body and the inner wall surface of the second tank body together constitute the inner wall surface of the heat exchange channel 50.

[0058] In this embodiment, the heat exchange channel 50 is defined by the inner wall surfaces of the first tank body on the first metal layer 10 and the second tank body on the second metal layer 30, which can make full use of the thicknesses of the first metal layer 10 and the second metal layer 30.

[0059] In some specific embodiments of the present application, a first partition rib 11 is provided on the second side of the first metal layer 10. The first partition rib 11 is connected to the second metal layer 30. The first partition rib 11 is located within the heat exchange flow channel 50. In the width direction of the heat exchange flow channel 50, the first partition rib 11 divides the heat exchange flow channel 50 into multiple sub-flow channels.

[0060] That is to say, as Figure 3 shown, the first partition rib 11 is provided in the area corresponding to the heat exchange flow channel 50 on the second side of the first metal layer 10. The first partition rib 11 extends along the extension direction of the heat exchange flow channel 50, and the first partition rib 11 is fixedly connected to the second metal layer 30. In this way, the heat exchange flow channel 50 can be divided into multiple sub-flow channels to meet different heat exchange requirements. If no first groove is provided on the first metal layer 10 and only the first partition rib 11 is provided, the processing of the first partition rib 11 will not be affected by the width of the groove, so that finer flow channels can be divided, which is beneficial to improving the heat exchange performance of the flexible heat exchange plate 100.

[0061] According to an embodiment of the present application, a second partition rib 31 is provided on the first side of the second metal layer 30. The second partition rib 31 is connected to the first metal layer 10. The second partition rib 31 and the first partition rib 11 are arranged at intervals or correspondingly in the width direction of the heat exchange flow channel 50. The second partition rib 31 is located within the heat exchange flow channel 50. In the width direction of the heat exchange flow channel 50, the first partition rib 11 and the second partition rib 31 divide the heat exchange flow channel 50 into multiple sub-flow channels.

[0062] Specifically, as Figure 3 shown, the second partition rib 31 is provided in the area corresponding to the heat exchange flow channel 50 on the first side of the second metal layer 30. The second partition rib 31 extends along the extension direction of the heat exchange flow channel 50. The second partition rib 31 is fixedly connected to the first metal layer 10. In this way, the heat exchange flow channel 50 can be divided into multiple sub-flow channels, which is beneficial to increasing the contact area between the heat exchange liquid and the flexible heat exchange plate 100 and is beneficial to improving the heat exchange performance of the flexible heat exchange plate 100.

[0063] If no second groove is provided on the second metal layer 30 and only the second partition rib 31 is provided, the processing of the second partition rib 31 will not be affected by the width of the groove, so that finer flow channels can be divided, which is beneficial to improving the heat exchange performance of the flexible heat exchange plate 100.

[0064] It should be noted that the setting positions of the second partition rib 31 and the first partition rib 11 include the following situations:

[0065] Situation 1: As Figure 4As shown, the first partition rib 11 and the second partition rib 31 are located in the same heat exchange flow channel 50. In the thickness direction of the flexible heat exchange plate 100, the projection of the first partition rib 11 on the second heat exchange plate coincides with the second partition rib 31. In this case, the sum of the heights of the first partition rib 11 and the second partition rib 31 is equal to the height of the heat exchange flow channel 50, and the heat exchange flow channel 50 is divided into multiple sub-flow channels by the first partition rib 11 and the second partition rib 31;

[0066] Case 2: The first partition rib 11 is located in the first heat exchange flow channel, and the second partition rib 31 is located in the second heat exchange flow channel. The first partition rib 11 divides the first heat exchange flow channel into multiple sub-flow channels, and the second partition rib 31 divides the second heat exchange flow channel into multiple sub-flow channels.

[0067] Case 3: As Figure 3 shown, the first partition rib 11 and the second partition rib 31 are located in the same heat exchange flow channel 50. In the thickness direction of the flexible heat exchange plate 100, the projection of the first partition rib 11 on the second heat exchange plate is spaced apart from the second partition rib 31, and the heat exchange flow channel 50 is divided into multiple sub-flow channels by the first partition rib 11 and the second partition rib 31.

[0068] In some specific embodiments of the present application, the first metal layer 10 and the second metal layer 30 are connected by welding.

[0069] That is to say, the first metal layer 10 and the second metal layer 30 can be connected together by welding, which is convenient for connection and does not require the use of other adhesives, which is beneficial to making the thickness of the flexible heat exchange plate 100 thinner.

[0070] According to an embodiment of the present application, the welding method between the first metal layer 10 and the second metal layer 30 is diffusion welding or penetration welding.

[0071] Specifically, when the first metal layer 10 and the second metal layer 30 are connected by diffusion welding, the thermal stress distribution in the entire welding area can be ensured to be uniform, thereby reducing thermal deformation during the welding process, and the welding efficiency is high. In addition, diffusion welding can ensure the connection strength between the two metal layers, and at the same time, since the metal does not need to be melted, it is suitable for connecting thinner metal layers.

[0072] Optionally, the first metal layer 10 and the second metal layer 30 are welded together by penetration welding, which can ensure the connection strength between the first metal layer 10 and the second metal layer 30.

[0073] In some specific embodiments of the present application, the first metal layer 10 and the second metal layer 30 are made of the same material. On the one hand, it can simplify the materials used for the flexible heat exchange plate 100, and on the other hand, it can ensure the reliability of the welding between the first metal layer 10 and the second metal layer 30.

[0074] In some embodiments of the present application, the materials of the first metal layer 10 and the second metal layer 30 are copper.

[0075] According to an embodiment of the present application, the ratio of the depth of the first groove to the thickness of the first metal layer 10 ranges from 0.1 to 0.9; and / or, the ratio of the depth of the second groove to the thickness of the second metal layer 30 ranges from 0.1 to 0.9.

[0076] If the ratio of the depth of the first groove to the thickness of the first metal layer 10 is too large, the first metal layer 10 may become weak, which is not conducive to processing; if the ratio of the depth of the first groove to the thickness of the first metal layer 10 is too small, the contact area between the heat exchange liquid and the first metal layer 10 will be small, which is not conducive to improving the heat exchange efficiency. In this embodiment, the ratio of the depth of the first groove to the thickness of the first metal layer 10 is controlled within the range of 0.1 to 0.9. For example, 0.1, 0.3, 0.5, 0.7, and 0.9, etc. Within this range, both the structural strength and processing feasibility of the flexible heat exchange plate 100 can be ensured, and the heat exchange efficiency can be optimized.

[0077] Correspondingly, if the ratio of the depth of the second groove to the thickness of the second metal layer 30 is too large, the second metal layer 30 may become weak, which is not conducive to processing; if the ratio of the depth of the second groove to the thickness of the second metal layer 30 is too small, the contact area between the heat exchange liquid and the second metal layer 30 will be small, which is not conducive to improving the heat exchange efficiency. In this embodiment, the ratio of the depth of the second groove to the thickness of the second metal layer 30 is controlled within the range of 0.1 to 0.9. For example, 0.1, 0.3, 0.5, 0.7, and 0.9, etc. Within this range, both the structural strength and processing feasibility of the flexible heat exchange plate 100 can be ensured, and the heat exchange efficiency can be optimized.

[0078] In some specific embodiments of the present application, the thicknesses of the first metal layer 10 and the second metal layer 30 are 0.03 mm to 0.2 mm respectively, and the depths of the first groove and the second groove are 0.025 mm to 0.14 mm respectively.

[0079] Specifically, the thickness of the first metal layer 10 is between 0.03 mm and 0.2 mm. For example, the thickness of the first metal layer 10 can be 0.03 mm, 0.08 mm, 0.13 mm, 0.18 mm, and 0.2 mm, etc. Within this range, both the processing feasibility and the appropriate thickness range of the flexible heat exchange plate 100 can be ensured.

[0080] The depth of the first groove body is between 0.025 mm and 0.14 mm. For example, the thickness of the first groove body can be 0.025 mm, 0.05 mm, 0.075 mm, 0.1 mm, 0.14 mm, etc., and the ratio of the depth of the first groove body to the thickness of the first metal layer 10 can be between 0.1 and 0.9. This can ensure both the feasibility of processing and the heat exchange performance of the flexible heat exchange plate 100.

[0081] Correspondingly, the thickness of the second metal layer 30 is between 0.03 mm and 0.2 mm. For example, the thickness of the second metal layer 30 can be 0.03 mm, 0.08 mm, 0.13 mm, 0.18 mm, 0.2 mm, etc. Within this range, both the feasibility of processing and the appropriate thickness range of the flexible heat exchange plate 100 can be ensured.

[0082] The depth of the second groove body is between 0.025 mm and 0.14 mm. For example, the thickness of the second groove body can be 0.025 mm, 0.05 mm, 0.075 mm, 0.1 mm, 0.14 mm, etc., and the ratio of the depth of the second groove body to the thickness of the second metal layer 30 can be between 0.1 and 0.9. This can ensure both the feasibility of processing and the heat exchange performance of the flexible heat exchange plate 100.

[0083] According to an embodiment of the present application, the thicknesses of the first polymer layer 20 and the second polymer layer 40 are the same.

[0084] That is to say, the thicknesses of the first polymer layer 20 and the second polymer layer 40 can be the same or different. In this embodiment, the thicknesses of the first polymer layer 20 and the second polymer layer 40 are the same. This design can ensure that the bending performance of the flexible heat exchange plate 100 in two directions is consistent, improve the stability and reliability of the product, and at the same time simplify the production process of the flexible heat exchange plate 100.

[0085] In some alternative examples of the present application, the thicknesses of the first polymer layer 20 and the second polymer layer 40 are respectively 0.03 mm to 0.05 mm. Within this range, both the structural strength and flexibility of the flexible heat exchange plate 100 can be ensured, and the problem of the flexible heat exchange plate 100 being too thick can be avoided.

[0086] All in all, for the flexible heat exchange plate 100 provided according to this embodiment, by providing the first metal layer 10 and the second metal layer 30, the heat conduction ability of the flexible heat exchange plate 100 can be effectively improved, thereby effectively improving the heat exchange performance of the flexible heat exchange plate 100; at the same time, by providing the first polymer layer 20 and the second polymer layer 40, the structural strength and flexibility of the flexible heat exchange plate 100 can be ensured, so that the flexible heat exchange plate 100 can meet different usage requirements.

Since the flexible heat exchange plate 100 according to the embodiments of the present application has the above technical effects, the heat exchange module according to the embodiments of the present application also has corresponding technical effects, which will not be elaborated in this embodiment.
