Detailed Implementation

[0035] 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.

[0038] 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.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] 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.

[0041] Please refer to Figures 1-5 This embodiment provides a flow channel plate 100, which includes a main body 110 and a resin plate 120. The resin plate 120 is bonded to the main body 110, and the main body 110 and the resin plate 120 are jointly formed to form a heat exchange flow channel 103.

[0042] Please refer to Figures 1-5 The working principle of the flow channel plate 100 is as follows:

[0043] The flow channel plate 100 connects the resin plate 120 to the main body 110 by adhesive bonding and is used in heat exchangers. This method eliminates the need for furnace brazing, thereby reducing carbon emissions during production and preventing flux residue in the flow channel, which helps improve product cleanliness and avoids flow channel blockage.

[0044] It should also be noted that when bonding the resin board 120 to the main body 110, epoxy resin or other adhesives can be used for bonding and sealing, thus eliminating the need for furnace brazing. This reduces carbon emissions from brazing during production, and the finished product has no flux residue left in the flow channel, which helps to improve the cleanliness of the product.

[0045] In addition, based on the structural design of the resin plate 120, compared with the existing metal plate, the resin plate 120 is made of resin material, which has stronger molding ability and can form more complex flow channels, greatly enhancing the heat exchange efficiency and thermal conductivity of the flow channel plate 100.

[0046] It should be noted that the main body 110 can be made of metal to improve its structural strength. Moreover, based on the structure of the resin plate 120, the complex flow channel structure inside can be formed on the inner side of the resin plate 120. That is, the complex flow channel structure can be formed on the surface of the heat exchange flow channel 103 formed on the resin plate 120. This simplifies the structural design of the main body 110, thereby improving its flexibility of use and reducing its manufacturing cost.

[0047] It is understood that in this embodiment, the heat exchange channel 103 has an inlet 101 and an outlet 102, and both the inlet 101 pipe and the outlet 102 pipe are connected to the main body 110. The flow direction of the heat exchange channel 103 can be adjusted according to actual needs. In this embodiment, the heat exchange channel 103 is described as a U-shaped channel, that is, the beginning and end of the heat exchange channel 103 are located on the same side of the channel plate 100.

[0048] Furthermore, based on the above, please refer to... Figures 1-7 In this embodiment, when configuring the resin plate 120, in order to improve its flexibility of use, the resin plate 120 can be configured to include multiple sub-plate bodies 121, the multiple sub-plate bodies 121 are arranged in an array, and each sub-plate body 121 and the corresponding main body 110 region together form a sub-flow channel 104; wherein, the multiple sub-flow channels 104 are sequentially connected to form a heat exchange channel 103.

[0049] That is, the resin board 120 can be assembled in a modular manner, which helps to reduce its manufacturing cost and facilitates later maintenance and installation; in addition, it also facilitates the molding of more complex and diverse flow channel structures.

[0050] Furthermore, this method divides the heat exchange channel 103 into multiple segments along its extension direction, as shown in the example below. Figure 3 As shown by the middle arrow, each heat exchange channel 103 corresponds to a sub-channel 104, that is, multiple sub-channels 104 are connected in sequence to form the heat exchange channel 103.

[0051] Please refer to Figures 1-12 Furthermore, based on the configuration of multiple sub-plates 121, in order to sequentially connect the multiple sub-channels 104 along the extension direction of the heat exchange channel 103, multiple guide grooves 122 are arranged on the sides of adjacent sub-plates 121 that abut against each other along the extension direction of the heat exchange channel 103. The guide grooves 122 connect the adjacent sub-channels 104. It should be noted that the guide grooves 122 are arranged on the sides of each sub-plate 121 that contact the adjacent sub-plate 121, and are opened along the extension direction of the heat exchange channel 103. Moreover, the opening of the guide grooves 122 faces the main plate 110. The purpose is to connect the adjacent sub-channels 104 after each sub-plate 121 is connected to the main plate 110.

[0052] This method simplifies the structure of the flow channel plate 100, and the flow guide groove 122 can be integrally formed with each sub-plate body 121, thereby simplifying its structural settings. After each sub-plate body 121 is bonded to the main body 110, the corresponding sub-flow channel 104 can be formed, and each sub-flow channel 104 can be simultaneously guided according to the preset flow direction, thereby simplifying its structural settings and reducing its manufacturing cost.

[0053] Furthermore, in this embodiment, as can be seen from the foregoing, the resin plate 120 provided in this embodiment is made of resin material. Based on this, it is possible to form complex and diverse flow channel structures. That is, the flow direction and related style of the heat exchange flow channel 103 can be set according to its actual needs. In this embodiment, one flow channel style is used as an example for explanation.

[0054] Please refer to Figures 1-13 When installing multiple sub-boards 121, in order to improve the stability of their installation, in addition to bonding the sub-boards 121 to the main board 110, two adjacent sub-boards 121 can be bonded together. A snap-fit ​​structure can also be configured at the connection between two adjacent sub-boards 121 to improve the stability and sealing of the connection.

[0055] There are various ways to configure the snap-fit ​​structure. In this embodiment, a first snap-fit ​​part 123 and a second snap-fit ​​part 124 are respectively configured on the side where two adjacent sub-plates 121 abut against each other along the extension direction of the heat exchange channel 103. The first snap-fit ​​part 123 and the second snap-fit ​​part 124 engage. That is, when configuring the above-mentioned snap-fit ​​structure, multiple sub-plates 121 are sequentially snap-fit ​​connected along the extension direction of the heat exchange channel 103.

[0056] Furthermore, in order to improve the sealing performance of the first snap-fit ​​portion 123 and the second snap-fit ​​portion 124, the first snap-fit ​​portion 123 may include a slot 125 provided along the contour of the guide groove 122, and the second snap-fit ​​portion 124 may include a platform 126 provided along the contour of the guide groove 122, and the slot 125 may be used for insertion and engagement with the slot 125. It should be noted that, as described above, this embodiment uses a flow guide groove 122 on the side of the sub-plate 121 to connect two adjacent sub-channels 104. Based on this, along the extension direction of the heat exchange channel 103, corresponding sides of two adjacent sub-plates 121 are provided with slots 125. Thus, one of the adjacent and correspondingly cooperating first latching part 123 and second latching part 124 is a slot 125 and the other is a latching platform 126. Both are arranged around the contour of the flow guide groove 122, so that the slot 125 can be inserted and cooperated with the latching platform 126 and is adapted to the structure of the aforementioned flow guide groove 122, thereby improving the connection stability and sealing performance.

[0057] Further, please refer to Figures 1-13 In this embodiment, in order to guide the fluid in the heat exchange channel 103 from its inlet 101 to its outlet 102, a corresponding flow guiding structure is provided in each sub-channel 104. The flow guiding structure can be provided on the inner side of the sub-plate 121 or on the inner side of the main plate 110. Specifically, in this embodiment, multiple first flow guiding platforms 127 are provided on the side of each sub-plate 121 forming the sub-channel 104, that is, multiple first flow guiding platforms 127 are arranged on the inner side of the sub-plate 121.

[0058] Moreover, the multiple first guide platforms 127 are arranged in multiple rows, and each row of first guide platforms 127 is set along the extension direction of the heat exchange channel 103; wherein, the first guide platform 127 is used to guide the fluid in the heat exchange channel 103 to flow from the inlet 101 to the outlet 102 of the heat exchange channel 103.

[0059] Furthermore, the first guide platform 127 described above can guide the flow of fluid in the sub-channel 104. The first guide platform 127 includes a first guide block 128 and a second guide block 129, which are connected at an angle. The distance between the first guide block 128 and the second guide block 129 gradually increases along the direction from the inlet 101 to the outlet 102 of the heat exchange channel 103. This results in the first guide platform 127 having a V-shaped or Y-shaped structure, thereby preventing backflow.

[0060] Based on the first flow guide 127 mentioned above, a corresponding structure can also be provided on the inner side of the main body 110, that is, the main body 110 is arranged with multiple second flow guides 111 in an array, the multiple second flow guides 111 are arranged in multiple columns, and each column of second flow guides 111 is arranged along the extension direction of the heat exchange channel 103.

[0061] In addition, in order to reduce the thickness of the flow channel plate 100, multiple rows of first flow guides 127 and multiple rows of second flow guides 111 can be arranged in a staggered order. That is, the arrangement direction of the first flow guides 127 is the same as the arrangement direction of the second flow guides 111, but they are arranged in a staggered order, so that there is a second flow guide 111 between two adjacent first flow guides 127.

[0062] Furthermore, based on the aforementioned structures of the first guide platform 127 and the second guide platform 111, to improve the structural strength of the flow channel plate 100, multiple abutment platforms 131 are arranged between each row of first guide platforms 127, and each abutment platform 131 corresponds to a row of second guide platforms 111. In this way, it can both guide the flow and increase the strength of the flow channel plate 100. Similarly, the abutment platforms 131 can also be arranged on the inner side of the main body 110, located between two adjacent second guide platforms 111, and used to abut against the first guide platform 127.

[0063] In addition to the above structure, to improve the connection stability between the resin board 120 and the main board 110, multiple riveting grooves can be provided on the outer edge of each sub-board 121, and multiple riveting holes can be provided on the outer edge of the main board 110. In this way, the flow channel board 100 can be connected based on the above structure, and can also be riveted using the multiple riveting grooves and riveting holes on its outer edge, thereby improving the connection stability.

[0064] It should also be noted that this embodiment uses a U-shaped flow channel 103 as an example for illustration. Based on the above structure, it can also be set as an I-shaped flow channel or an L-shaped flow channel, etc. Furthermore, the structure of its internal flow channel can be adjusted according to actual needs. That is, based on the structure of the resin plate 120, its molding capability is stronger and it can form more complex flow channels. Its internal flow channel structure can be flexibly designed, which greatly enhances the heat exchange efficiency and thermal conductivity of the heat exchanger.

[0065] Based on the above, please refer to Figures 1-13This embodiment also provides a heat exchanger, which includes at least one of the aforementioned flow channel plates 100. The flow channel plates 100 of this heat exchanger are bonded together with a resin plate 120 to a main body 110. This eliminates the need for furnace brazing during the fabrication of the flow channel plates 100, thereby reducing carbon emissions during production and preventing flux residue in the flow channels, thus improving product cleanliness and preventing flow channel blockage. It should also be noted that, based on the structural design of the resin plate 120, compared to existing metal plates, the resin plate 120 is made of resin-based materials, which has stronger molding capabilities and can form more complex flow channels, greatly enhancing the heat exchanger's heat exchange efficiency and thermal conductivity.

[0066] 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.
