It should be noted that the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0028] The following description of at least one illustrative embodiment is merely exemplary in nature and is in no way intended to limit the application or its application or uses.

[0029] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, such techniques, methods, and apparatus should be considered as being part of the specification.

[0030] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation on the application. Thus, other examples of the exemplary embodiments can have different values.

[0031] It should be noted that like reference numerals and letters refer to like items throughout the drawings, and thus, once an item is defined in one drawing, it is not necessary to discuss it further in subsequent drawings.

[0032] The flexible heat exchange plate 100 according to the embodiments of the present application will first be described in detail below with reference to the drawings.

[0033] As shown in FIGS. 1-4, the flexible heat exchange plate 100 according to the embodiment of the present application comprises a first metal layer 10 and a second metal layer 30.

[0034] Specifically, the first side of the first metal layer 10 is provided with a first polymer layer 20, the first side of the second metal layer 30 is connected with the second side of the first metal layer 10, and the second side of the second metal layer 30 is provided with a second polymer layer 40; 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 the inner wall surface of the groove and the other one define a heat exchange flow channel 50.

[0035] In other words, as shown in FIGS. 1-4, the flexible heat exchange plate 100 according to the embodiment of the present application mainly comprises 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 and fixedly connected together in a laminated manner. At least one of the 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 the 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 inner wall surface of the groove and the surface of the adjacent metal layer can define the required heat exchange flow channel 50.

[0036] Further, the side of the first metal layer 10 away from the second metal layer 30 (i.e., the first side of the first metal layer 10) is provided with a first polymer layer 20, 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 adapt to a complex installation space, the first polymer layer 20 can effectively disperse stress and avoid damage to the first metal layer 10 due to excessive bending.

[0037] Correspondingly, the side of the second metal layer 30 away from the first metal layer 10 (i.e., the second side of the second metal layer 30) is provided with a second polymer layer 40, 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 adapt to a complex installation space, the second polymer layer 40 can effectively disperse stress and avoid damage to the second metal layer 30 due to excessive bending.

[0038] 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, and the embodiment will not be described again.

[0039] Therefore, the flexible heat exchange plate 100 provided by the embodiment can effectively improve the heat conduction capacity of the flexible heat exchange plate 100 through the first metal layer 10 and the second metal layer 30, thereby effectively improving the heat exchange performance of the flexible heat exchange plate 100. Meanwhile, the first high polymer layer 20 and the second high polymer layer 40 can ensure the structural strength and flexibility of the flexible heat exchange plate 100, so that the flexible heat exchange plate 100 can meet different use requirements.

[0040] In some optional examples of the application, the material of the first metal layer 10 and the second metal layer 30 can be a copper layer, an aluminum layer, or a stainless steel layer.

[0041] According to one embodiment of the application, the second side of the first metal layer 10 is provided with a first groove body, and the inner wall surface of the first groove body and the first side of the second metal layer 30 define a first heat exchange flow channel; and / or, the first side of the second metal layer 30 is provided with a second groove body, and the inner wall surface of the second groove body and the second side of the first metal layer 10 define a second heat exchange flow channel.

[0042] That is, the specific structure of the heat exchange flow channel 50 includes the following cases:

[0043] Case one, as shown in FIG. 2, the second side of the first metal layer 10 is provided with a first groove body, and the inner wall surface of the first groove body and the first side of the second metal layer 30 define a first heat exchange flow channel, and the inner wall surface of the first groove body and the surface of the first side of the second metal layer 30 corresponding to the first groove body form the inner wall surface of the first heat exchange flow channel.

[0044] In this case, the first heat exchange flow channel is close to the first side of the flexible heat exchange plate 100, which is conducive to improving the heat exchange effect of the first side of the flexible heat exchange plate 100.

[0045] Case two, the first side of the second metal layer 30 is provided with a second groove body, and the inner wall surface of the second groove body and the second side of the first metal layer 10 define a second heat exchange flow channel, and the inner wall surface of the second groove body and the surface of the second side of the first metal layer 10 corresponding to the second groove body form the inner wall surface of the second heat exchange flow channel.

[0046] In this case, the second heat exchange flow channel is close to the second side of the flexible heat exchange plate 100, which is conducive to improving the heat exchange effect of the second side of the flexible heat exchange plate 100.

[0047] Case three, the second side of the first metal layer 10 is provided with a first groove body, and the inner wall surface of the first groove body and the first side of the second metal layer 30 define a first heat exchange flow channel, and the first side of the second metal layer 30 is provided with a second groove body, and the inner wall surface of the second groove body and the second side of the first metal layer 10 define a second heat exchange flow channel.

[0048] In this case, the first heat exchange flow channel is close to the first side of the flexible heat exchange plate 100, and the second heat exchange flow 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 zones with different heat exchange performances, and the applicability of the flexible heat exchange plate 100 is effectively improved.

[0049] In some embodiments of the present application, the first heat exchange flow channel and the second heat exchange flow channel are in communication.

[0050] In other words, the first heat exchange flow channel and the second heat exchange flow channel can be used independently or in series. When the first heat exchange flow channel and the second heat exchange flow channel are used independently, the flexible heat exchange plate 100 is provided with two groups of liquid passages, one group of liquid passages is in communication with the first heat exchange flow channel, and the other group of liquid passages is in communication with the second heat exchange flow channel. Specifically, the first liquid passage of the first group of liquid passages is in communication with the first end of the first heat exchange flow channel, and the second liquid passage of the first group of liquid passages is in communication with the second end of the first heat exchange flow channel; the first liquid passage of the second group of liquid passages is in communication with the first end of the second heat exchange flow channel, and the second liquid passage of the second group of liquid passages is in communication with the second end of the second heat exchange flow channel. Thus, the heat exchange liquid in the first heat exchange flow channel and the second heat exchange flow channel can be independently driven by different micropumps.

[0051] When the first heat exchange flow channel and the second heat exchange flow channel are used in series, the first end of the first heat exchange flow channel is in communication with the first end of the second heat exchange flow channel, for example, the positions of the part of one end of the first groove body and the part of one end of the second groove body correspond to each other, so that the first end of the first heat exchange flow channel is in communication with the first end of the second heat exchange flow channel. In this case, the flexible heat exchange plate 100 is provided with one group of liquid passages, the first liquid passage of the group of liquid passages is in communication with the second end of the first heat exchange flow channel, and the second liquid passage of the group of liquid passages is in communication with the second end of the second heat exchange flow channel. Thus, the heat exchange liquid in the first heat exchange flow channel and the second heat exchange flow channel can be driven together by one micropump.

[0052] According to an embodiment of the present application, the second side of the first metal layer 10 is provided with a first groove body, and the first side of the second metal layer 30 is provided with a second groove body, and the inner wall surface of the first groove body and the inner wall surface of the second groove body define the heat exchange flow channel 50.

[0053] Specifically, the second side of the first metal layer 10 is provided with a first groove body, and the shape of the first groove body can be a serpentine structure, and the first side of the second metal layer 30 is provided with a second groove body, and the projection of the first groove body on the second metal layer 30 overlaps the second groove body in the thickness direction of the flexible heat exchange plate 100, so that the inner surface of the first groove body and the inner wall surface of the second groove body define the heat exchange flow channel 50, that is, the inner wall surface of the first groove body and the inner wall surface of the second groove body jointly constitute the inner wall surface of the heat exchange flow channel 50.

[0054] In the embodiment, the heat exchange flow channel 50 is defined by the inner wall surface of the first groove on the first metal layer 10 and the second groove on the second metal layer 30, and the thickness of the first metal layer 10 and the second metal layer 30 can be fully utilized.

[0055] In some embodiments of the present application, the second side of the first metal layer 10 is provided with a first partition rib 11, the first partition rib 11 is connected with the second metal layer 30, and the first partition rib 11 is located in 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 a plurality of sub-flow channels.

[0056] That is, as shown in FIG. 3, the second side of the first metal layer 10 is provided with a first partition rib 11 in the region corresponding to the heat exchange flow channel 50, 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 with the second metal layer 30, so as to divide the heat exchange flow channel 50 into a plurality of sub-flow channels to meet different heat exchange requirements. If the first groove is not provided on the first metal layer 10, and only the first partition rib 11 is provided, the processing of the first partition rib 11 is not affected by the width of the groove, so that a finer flow channel can be divided, which is beneficial to improve the heat exchange performance of the flexible heat exchange plate 100.

[0057] According to an embodiment of the present application, the first side of the second metal layer 30 is provided with a second partition rib 31, the second partition rib 31 is connected with the first metal layer 10, the second partition rib 31 is arranged in the heat exchange flow channel 50, and the first partition rib 11 and the second partition rib 31 divide the heat exchange flow channel 50 into a plurality of sub-flow channels in the width direction of the heat exchange flow channel 50.

[0058] Specifically, as shown in FIG. 3, the first side of the second metal layer 30 is provided with a second partition rib 31 in the region corresponding to the heat exchange flow channel 50, the second partition rib 31 extends along the extension direction of the heat exchange flow channel 50, and the second partition rib 31 is fixedly connected with the first metal layer 10, so as to divide the heat exchange flow channel 50 into a plurality of sub-flow channels, which is beneficial to increase the contact area of the heat exchange liquid and the flexible heat exchange plate 100, and improve the heat exchange performance of the flexible heat exchange plate 100.

[0059] If the second groove is not provided on the second metal layer 30, and only the second partition rib 31 is provided, the processing of the second partition rib 31 is not affected by the width of the groove, so that a finer flow channel can be divided, which is beneficial to improve the heat exchange performance of the flexible heat exchange plate 100.

[0060] It should be noted that the arrangement positions of the second partition rib 31 and the first partition rib 11 include the following cases:

[0061] In case one, as shown in FIG. 4, the first partition rib 11 and the second partition rib 31 are located in the same heat exchange channel 50, and 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 channel 50, and the heat exchange channel 50 is divided into multiple sub-channels by the first partition rib 11 and the second partition rib 31.

[0062] In case two, the first partition rib 11 is located in the first heat exchange channel, and the second partition rib 31 is located in the second heat exchange channel. The first partition rib 11 divides the first heat exchange channel into multiple sub-channels, and the second partition rib 31 divides the second heat exchange channel into multiple sub-channels.

[0063] In case three, as shown in FIG. 3, the first partition rib 11 and the second partition rib 31 are located in the same heat exchange channel 50, and 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. The heat exchange channel 50 is divided into multiple sub-channels by the first partition rib 11 and the second partition rib 31.

[0064] In some embodiments of the present application, the first metal layer 10 and the second metal layer 30 are welded.

[0065] That is, the first metal layer 10 and the second metal layer 30 can be connected together by welding, which is convenient and does not require the use of other adhesives, and is conducive to making the thickness of the flexible heat exchange plate 100 thinner.

[0066] According to an embodiment of the present application, the welding method of the first metal layer 10 and the second metal layer 30 is diffusion welding or penetration welding.

[0067] Specifically, the first metal layer 10 and the second metal layer 30 are connected by diffusion welding, which can ensure uniform distribution of thermal stress in the entire welding area, thereby reducing thermal deformation during welding, and has high welding efficiency. In addition, diffusion welding can ensure the connection strength between the two metal layers, and because the metal does not need to be melted, it is suitable for connecting thin metal layers.

[0068] Alternatively, the first metal layer 10 and the second metal layer 30 are welded together by penetration welding, which can ensure the connection strength of the first metal layer 10 and the second metal layer 30.

[0069] In some embodiments of the present application, the first metal layer 10 and the second metal layer 30 are made of the same material, which can simplify the use of materials of the flexible heat exchange plate 100 on the one hand, and ensure the reliability of the welding of the first metal layer 10 and the second metal layer 30 on the other hand.

[0072] 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 can 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 is small, which is not conducive to improving the heat exchange efficiency. In the present embodiment, the ratio of the depth of the first groove to the thickness of the first metal layer 10 is controlled in the range of 0.1-0.9, for example, 0.1, 0.3, 0.5, 0.7 and 0.9, etc., under which the structural strength and processing feasibility of the flexible heat exchange plate 100 can be ensured, and the heat exchange efficiency can be optimized.

[0073] 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 can 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 is small, which is not conducive to improving the heat exchange efficiency. In the present embodiment, the ratio of the depth of the second groove to the thickness of the second metal layer 30 is controlled in the range of 0.1-0.9, for example, 0.1, 0.3, 0.5, 0.7 and 0.9, etc., under which the structural strength and processing feasibility of the flexible heat exchange plate 100 can be ensured, and the heat exchange efficiency can be optimized.

[0074] In some specific embodiments of the present application, the thickness of the first metal layer 10 and the second metal layer 30 is respectively 0.03mm-0.2mm, and the depth of the first groove and the second groove is respectively 0.025mm-0.14mm.

[0075] Specifically, the thickness of the first metal layer 10 is between 0.03mm and 0.2mm, for example, the thickness of the first metal layer 10 can be 0.03mm, 0.08mm, 0.13mm, 0.18mm and 0.2mm, etc., under which the processing feasibility can be ensured, and the flexible heat exchange plate 100 can be ensured in a suitable thickness range.

[0076] The depth of the first groove is between 0.025mm and 0.14mm, for example, the thickness of the first groove can be 0.025mm, 0.05mm, 0.075mm, 0.1mm and 0.14mm, etc., and the ratio of the depth of the first groove to the thickness of the first metal layer 10 can be between 0.1 and 0.9, which can ensure the feasibility of processing and the heat exchange performance of the flexible heat exchange plate 100.

[0077] Correspondingly, the thickness of the second metal layer 30 is between 0.03mm and 0.2mm, for example, the thickness of the second metal layer 30 can be 0.03mm, 0.08mm, 0.13mm, 0.18mm and 0.2mm, etc., which can ensure the feasibility of processing and the thickness of the flexible heat exchange plate 100.

[0078] The depth of the second groove is between 0.025mm and 0.14mm, for example, the thickness of the second groove can be 0.025mm, 0.05mm, 0.075mm, 0.1mm and 0.14mm, etc., and the ratio of the depth of the second groove to the thickness of the second metal layer 30 can be between 0.1 and 0.9, which can ensure the feasibility of processing and the heat exchange performance of the flexible heat exchange plate 100.

[0079] According to an embodiment of the present application, the thickness of the first polymer layer 20 and the second polymer layer 40 is the same.

[0080] That is, the thickness of the first polymer layer 20 and the second polymer layer 40 can be the same or different, in this embodiment, the thickness of the first polymer layer 20 and the second polymer layer 40 is the same, which can ensure the bending performance of the flexible heat exchange plate 100 in two directions, improve the stability and reliability of the product, and simplify the production process of the flexible heat exchange plate 100.

[0081] In some optional examples of the present application, the thickness of the first polymer layer 20 and the second polymer layer 40 is between 0.03mm and 0.05mm, which can ensure the structural strength and flexibility of the flexible heat exchange plate 100, and avoid the problem of excessive thickness of the flexible heat exchange plate 100.
