[0032] 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.

[0033] Please refer to Figures 1-5This embodiment provides a heating core 100, which includes at least one heating unit 110 and at least two flow channel plates 120;

[0034] Two flow channel plates 120 are welded together, and at least a portion of the two flow channel plates 120 are spaced apart to form a heating zone 101; a heating unit 110 is housed within the heating zone 101.

[0035] Please refer to Figures 1-5 The working principle of the heating core 100 is as follows:

[0036] The heating core 100 is used in the heater 200. In this embodiment, the heating core 100 includes two flow channel plates 120 and a heating unit 110 disposed between the two flow channel plates 120. In other embodiments of this utility model, the number of flow channel plates 120 and the number of heating units 110 can be adjusted according to actual needs.

[0037] Specifically, the two flow channel plates 120 of the heating core 100 are connected by welding. When welding the two flow channel plates 120, the two flow channel plates 120 are arranged in parallel and spaced apart, so that the areas of the two flow channel plates 120 except for the welding connection area are spaced apart, thereby making at least a part of the areas of the two flow channel plates 120 spaced apart to form the heating zone 101.

[0038] As can be seen from the foregoing, while welding the two flow channel plates 120 together, it is possible to complete the docking assembly of the two flow channel plates 120 and reserve the heating area 101 for installing the heating unit 110. In this way, the assembly process can be optimized, thereby improving the assembly efficiency.

[0039] Therefore, by placing the heating unit 110 inside the heating zone 101, heating can be performed. Moreover, this method also makes it easy to clean the heating zone 101 after welding the two flow channel plates 120 together, avoiding the residue of welding waste in the heating zone 101, thereby ensuring the heating effect of the heating unit 110.

[0040] In summary, the heating core 100 is constructed by welding two flow channel plates 120 together. During the welding process, the partial spacing between the two flow channel plates 120 creates a heating zone 101 for mounting the heating unit 110. This allows for the welding connection to be performed before the installation of the heating unit 110 during the assembly of the heating core 100. This optimizes the assembly process by ensuring the welding step precedes the installation of the heating unit 110, preventing welding debris from falling into the heating zone 101. This avoids the debris affecting the contact between the heating unit 110 and the flow channel plates 120. Furthermore, this optimizes the assembly process, improves assembly efficiency, reduces assembly costs, enhances operational stability through welding, and prevents any impact on heating efficiency.

[0041] Further, please refer to Figures 1-5 In this embodiment, to improve heating efficiency, i.e., to improve heat transfer efficiency, the heating unit 110 is coated with a thermally conductive adhesive layer in the area where the heating unit 110 contacts the flow channel plate 120. This allows the heat generated by the heating unit 110 to be efficiently transferred to the fluid within the flow channel plate 120.

[0042] As can be seen from the above, in this embodiment, the two flow channel plates 120 are connected by welding. On this basis, in order to improve the efficiency of welding connection and to make the welding connection of flow channel plates 120 form a standardized and modular process, this embodiment adopts that each flow channel plate 120 is provided with at least one welding part 121, which is used to weld to the welding part 121 of the adjacent flow channel plate 120.

[0043] That is, in this way, each flow channel plate 120 is provided with at least one welding part 121, so that when two flow channel plates 120 are joined together, the welding parts 121 on the two flow channel plates 120 are welded together, thereby improving the efficiency of welding connection. Furthermore, the welding part 121 is arranged to protrude from the flow channel plate 120. This arrangement not only facilitates positioning and improves welding efficiency, but also helps to maintain the spacing between the two flow channel plates 120.

[0044] Therefore, by providing the aforementioned welding section 121, the welding connection of the flow channel plate 120 can be standardized during the assembly process, thereby improving product assembly quality, increasing the consistency of batch product processing, and increasing the compatibility of the flow channel plate 120, which in turn helps to reduce the assembly and processing costs of the heating core 100. Furthermore, based on the configuration of the welding section 121, to improve welding quality, the outer edge of the welding section 121 is provided with an arc-shaped chamfer 122.

[0045] Further, please refer to Figures 1-5 Based on the above-mentioned welding part 121, this embodiment adopts a method in which two welding parts 121 are provided on one side of each flow channel plate 120, and the two welding parts 121 are arranged at intervals. In this way, when the two flow channel plates 120 are welded together, there are at least two welding points, which can improve the welding quality and the stability of the welding connection, thereby improving the performance of the heating core 100.

[0046] In addition, each flow channel plate 120 is equipped with a liquid inlet 123 and a liquid outlet 124; the aforementioned two welded parts 121 can be combined with the liquid inlet 123 and the liquid outlet 124, that is, the two welded parts 121 can be arranged in a ring around the liquid inlet 123 and the liquid outlet 124 respectively. In this way, the two welded parts 121 are located on the periphery of the liquid inlet 123 and the liquid outlet 124, thereby simplifying the structure of the heating core 100 and reducing its processing and assembly costs. In addition, this arrangement also helps to improve the sealing performance at the liquid inlet 123 and the liquid outlet 124.

[0047] Therefore, based on the above, when configuring two flow channel plates 120, except for the welded joint, the remaining areas of the two flow channel plates 120 are spaced to form heating zones 101. Furthermore, the welded joints 121 are located opposite each other at the inlet 123 and outlet 124. Thus, when configuring the heating zones 101, the inlet 123 and outlet 124 can be located at the same end of the flow channel plate 120, and the areas of the two adjacent flow channel plates 120, excluding the welded joints 121, are spaced apart. This allows the heating zones 101 to be located in the area of ​​the flow channel plate 120 excluding the inlet 123 and outlet 124. The inlet 123 and outlet 124 are used for fluid introduction and drainage. In this way, the heating unit 110 can heat the areas of the flow channel plate 120 excluding the fluid introduction and drainage areas, thereby optimizing the structure of the heating core 100 and improving heating efficiency.

[0048] Furthermore, to improve the installation stability and efficiency of the heating unit 110, a positioning platform is provided in the space between two adjacent flow channel plates 120, with the heating unit 110 located between the two welding parts 121 and the positioning platform. It should be noted that the purpose of the positioning platform is to improve the positioning and installation efficiency of the heating unit 110. Therefore, it can be positioned on one or both of the two flow channel plates 120 forming the heating zone 101, and it can be either fixedly connected to the flow channel plates 120 or detachably connected to them.

[0049] Based on the heating core 100 described above, please refer to... Figures 1-6 This embodiment also provides a heater 200, which includes an inlet pipe 210, an outlet pipe 220, and a heating core 100 as described in any of the foregoing embodiments; the inlet pipe 210 and the outlet pipe 220 are respectively connected to the inlet 123 and the outlet 124 of one of the flow channel plates 120.

[0050] By employing the aforementioned heating core 100, the heater 200 can be assembled by first welding the heating core 100 together and then installing the heating unit 110. This optimizes the assembly process by ensuring that the welding step precedes the installation of the heating unit 110, thereby preventing welding waste from falling into the heating zone 101. In other words, it prevents the waste from affecting the contact between the heating unit 110 and the flow channel plate 120. This optimizes the assembly process, improves assembly efficiency, reduces assembly costs, enhances operational stability through welding, and prevents the heating efficiency from being affected.

[0051] 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.
