[0035] Please refer to Figures 1-4 This embodiment provides a heating core 100, which includes a plurality of flow channel plates 110 and at least one heating unit 120;

[0036] Multiple flow channel plates 110 are arranged in parallel and at intervals, and each flow channel plate 110 includes a first forming plate 111, a second forming plate 112, and an inner fin assembly 113. The first forming plate 111 and the second forming plate 112 are welded together, and the first forming plate 111 and the second forming plate 112 together form a heat exchange cavity. The inner fin assembly 113 is housed in the heat exchange cavity and forms a heat exchange flow channel. The heat exchange flow channel is connected to the liquid inlet pipe 130 and the liquid outlet pipe 140 connected to one of the flow channel plates 110.

[0037] The heating unit 120 is disposed between two adjacent flow channel plates 110.

[0038] Please refer to Figures 1-4 The working principle of the heating core 100 is as follows:

[0039] The heating core 100 includes multiple flow channel plates 110 and at least one heating unit 120. The multiple flow channel plates 110 are arranged in parallel and spaced apart. Each flow channel plate 110 includes a first forming plate 111, a second forming plate 112, and an inner fin assembly 113. The first forming plate 111 and the second forming plate 112 are welded together, and the first forming plate 111 and the second forming plate 112 together form a heat exchange cavity. The inner fin assembly 113 is housed in the heat exchange cavity and forms a heat exchange channel. In this way, each flow channel plate 110 can be formed as a single unit structure. Then, by arranging two flow channel plates 110 in parallel and spaced apart, and on this basis, placing the heating unit 120 between two adjacent flow channel plates 110, the heating core 100 can be assembled quickly. After the assembly is completed, a structure to fix the two flow channel plates 110 can be set up.

[0040] It should be noted that in this embodiment, the arrangement of two flow channel plates 110 is used as an example for explanation. In other embodiments of this utility model, the number of flow channel plates 110 can be adjusted according to actual usage requirements. In the process of adjustment, as described above, each flow channel plate 110 is formed into a single structure in the aforementioned manner and then assembled accordingly.

[0041] In summary, the heating core 100 is used in heaters, and its structure is simple, the assembly process is simple, and the assembly efficiency can be improved.

[0042] Further, please refer to Figures 1-4 In the process of manufacturing the flow channel plate 110, in order to improve the efficiency of the positioning welding of the first forming plate 111 and the second forming plate 112, a first positioning baffle 114 is folded over on the outer edge of the first forming plate 111, and the first positioning baffle 114 is used to abut against the outer edge of the second forming plate 112; or, a second positioning baffle 115 is folded over on the outer edge of the second forming plate 112, and the second positioning baffle 115 is used to abut against the outer edge of the first forming plate 111.

[0043] That is, with this setting, during the manufacturing process of the flow channel plate 110, the positioning of the first forming plate 111 and the second forming plate 112 can be quickly completed by setting the first positioning baffle 114 or the second positioning baffle 115, and then the first forming plate 111 and the second forming plate 112 can be welded together.

[0044] In this embodiment, based on the above structure, a first positioning baffle 114 is provided by folding the outer edge of the first forming plate 111, and a second positioning baffle 115 is provided by folding the outer edge of the second forming plate 112; wherein, the folding direction of the first positioning baffle 114 is opposite to the folding direction of the second positioning baffle 115.

[0045] By simultaneously setting the first positioning baffle 114 and the second positioning baffle 115 as described above, the efficiency of manufacturing the flow channel plate 110 is improved. Furthermore, when configuring the first positioning baffle 114 and the second positioning baffle 115, to improve positioning accuracy, the first forming plate 111 is positioned along a first direction (e.g., ...). Figure 3 and Figure 4 A first positioning baffle 114 is provided on both sides opposite to the direction indicated by the middle arrow A, and the second forming plate 112 is arranged along the second direction (as shown by the middle arrow A). Figure 3 and Figure 4 A second positioning baffle 115 is provided on both sides opposite to the direction indicated by the middle arrow B; wherein the first direction is perpendicular to the second direction.

[0046] That is, by means of the above-mentioned arrangement, positioning can be achieved in both the first and second directions when positioning and connecting the first forming plate 111 and the second forming plate 112, thereby improving the assembly accuracy, thereby improving the assembly accuracy of the flow channel plate 110, and thus improving the manufacturing efficiency and quality of the heating core 100.

[0047] When the heating unit 120 is connected between the two flow channel plates 110, in order to improve heating efficiency, the area of ​​the heating unit 120 that is in contact with the flow channel plate 110 is covered with a thermally conductive adhesive layer.

[0048] Furthermore, based on the above structure, in order to ensure that the flow channel plate 110 can be tightly attached to the thermally conductive adhesive layer on the heating unit 120, when the heating unit 120 is placed between the two flow channel plates 110, a clip 20 can also be used to clip the two flow channel plates 110, thereby ensuring that the two flow channel plates 110 are tightly attached to the thermally conductive adhesive layer on the surface of the heating unit 120, and then they can be left to air dry or dried.

[0049] Further, please refer to Figures 1-4 In this embodiment, to improve the connection stability of the heating core 100, in addition to the above structure, a riveting portion can be provided on at least one side of each flow channel plate 110. The heating core 100 also includes a riveting member for riveting to the riveting portions of two adjacent flow channel plates 110. That is, the two flow channel plates 110 can be stably connected by the riveting member.

[0050] Furthermore, in this embodiment, after the two flow channel plates 110 are connected by riveting, in order to improve the connection stability of the heating core 100, each flow channel plate 110 has a protruding welding block 116 in the area opposite to the adjacent flow channel plate 110; and the welding block 116 is used to weld to the welding block 116 of the adjacent flow channel plate 110 after the two adjacent flow channel plates 110 are connected by riveting. That is, in this way, the connection stability of the heating core 100 can be improved after molding by connecting the two flow channel plates 110 by the above-mentioned riveting and welding.

[0051] Furthermore, when configuring the aforementioned welding block 116, it is arranged to protrude from the flow channel plate 110. The purpose is to ensure that the protrusion height of the welding block 116 can adapt to the gap between the two flow channel plates 110, thereby adapting to the installation of the heating unit 120.

[0052] Furthermore, in configuring the aforementioned welding block 116, this embodiment employs a welding ring configuration where the welding block 116 includes welding rings surrounding the inlet 117 or outlet 118 of the flow channel plate 110. This configuration allows the welding block 116 to adapt to the shape and contour of the inlet 117 or outlet 118, thereby simplifying the structure of the flow channel plate 110. Moreover, this embodiment uses two welding rings in each area of ​​each flow channel plate 110 opposite to the adjacent flow channel plate 110, with the two welding rings respectively surrounding the inlet 117 and outlet 118 of the flow channel plate 110. Therefore, in this way, welding can be performed around both the inlet 117 and outlet 118, thereby improving the stability and sealing of the connection.

[0053] In summary, please refer to Figures 1-4This embodiment also provides a heater that includes the heating core 100 described above, and the heater possesses all the advantages of the heating core 100 described above.

[0054] Based on the above, the manufacturing steps of the heating core 100 are as follows:

[0055] A first forming plate 111 and a second forming plate 112 are fabricated, and an inlet 117 and an outlet 118 are formed on the first forming plate 111 and the second forming plate 112, and a welding ring is protruded on the outer periphery of the inlet 117 and the outlet 118; wherein, the first forming plate 111 and the second forming plate 112 need to form a heat exchange cavity after assembly, therefore, their specific shape and the shape of the formed cavity need to be set according to the shape and outline of the inner fin assembly 113, which will not be described in detail here;

[0056] Then, the inner fin assembly 113 is installed, and the first forming plate 111 and the second forming plate 112 are positioned and assembled. When assembling the first forming plate 111 and the second forming plate 112, the positioning can be completed by the first positioning baffles 114 on both sides of the first forming plate 111 abutting against the outer edge of the second forming plate 112, and the second positioning baffles 115 on both sides of the second forming plate 112 abutting against the outer edge of the first forming plate 111. Then, the first forming plate 111 and the second forming plate 112 are welded together.

[0057] Please refer to Figures 1-4 Based on the above steps, a corresponding number of flow channel plates 110 for each unit are manufactured;

[0058] Then the heating unit 120 is placed between the two flow channel plates 110 and clamped by the clip 20. After the thermal conductive adhesive layer is set, the clip 20 is removed.

[0059] Then, the two flow channel plates 110 are riveted together using a riveting fitting;

[0060] Finally, the two flow channel plates 110 are welded together.

[0061] It should be noted that in the above steps, the riveting of the riveting parts can be set synchronously with the clamp 20, and the installation order of the riveting parts and the clamp 20 can be interchanged.

[0062] In summary, based on the above structural setup and steps, it can be seen that the processing and assembly steps of the heating core 100 and the heater using the heating core 100 are simple, the assembly is flexible, the range of applications is wide, the assembly efficiency can be improved, and the assembly and use costs can be reduced.

[0063] 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.
