Description

Technical Field

[0001] The utility model relates to the field of heating stoves, in particular to a heating body and a combined heating body. Background Art

[0002] In the relevant prior art, the copper tube of the heating body is completely sealed by the external aluminum plate. When the temperature of the aluminum plate or the copper tube rises too quickly, safety problems such as copper tube bursting are likely to occur. At the same time, during the manufacturing process, when the aluminum plate is die-cast directly on the outside of the copper tube, the copper tube cannot be fixed, so the copper tube is easily displaced and deformed during the die-casting process, affecting the subsequent heating work. Utility Model Content

The flow channel tube is bent and arranged inside the substrate. The substrate forms a flow channel protrusion corresponding to the flow channel tube. The heating thick film is arranged on a side of the substrate away from the flow channel protrusion. A notch is opened on the flow channel protrusion to expose part of the flow channel tube.

[0004] In the heating body of the embodiment of the utility model, when the temperature of the aluminum plate or the copper plate rises too quickly, the notch on the flow channel protrusion can quickly dissipate the heat, thereby ensuring that the temperature of the heating body is uniform and avoiding safety accidents; at the same time, in the manufacturing process of the heating body, the copper tube can be clamped and fixed at the notch position and then the aluminum substrate can be die-cast, so as to avoid direct die-casting of the copper tube in an unfixed state, which will cause the copper tube to shift and deform, and affect the heating efficiency of the heating body.

[0005] In the heating body of this embodiment, the flow channel protrusion has a long straight section and a curved section, and each of the long straight sections is provided with a notch.

[0006] In the heating body of this embodiment, each of the long straight sections is provided with a plurality of notches, and the plurality of notches are arranged at intervals.

[0007] In the heating body of this embodiment, the notch is opened along the radial direction of the flow channel protrusion.

[0008] In the heating body of this embodiment, the notches on different flow channel protrusions are arranged at intervals and are not connected to each other.

[0009] In the heating body of this embodiment, a fixing piece is further arranged in the substrate, and the fixing piece is formed in a shape matching the flow channel tube so as to be engaged and connected with the flow channel tube.

[0010] The combined heating body includes two heating bodies, and the two heating bodies are close together with one side facing away from the flow channel protrusion. A sealing groove is opened on the substrate of any heating body, and the sealing groove is located at the edge of the substrate and is at least arranged around the lower part of the heating thick film. A sealing ring is arranged in the sealing groove, and the two substrates clamp and press the sealing ring.

[0011] The sealing gasket can effectively prevent water from entering between the two heating elements, avoiding short circuit caused by the heating thick film contacting water, and greatly improving the safety and service life of the combined heating element.

[0016] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0017] See also Figure 1-2 The heating body provided in the embodiment of the utility model includes a substrate 1, a flow channel tube 2 and a heating thick film 3. The flow channel tube 2 is bent and arranged inside the substrate 1. The substrate 1 forms a flow channel protrusion 4 corresponding to the flow channel tube 2. The heating thick film 3 is arranged on the side of the substrate 1 away from the flow channel protrusion 4. A notch 5 is opened on the flow channel protrusion 4 to expose part of the flow channel tube 2.

[0018] In the heating body in the embodiment of the utility model, when the temperature of the aluminum plate or the copper plate rises too quickly, the notch 5 on the flow channel protrusion 4 can quickly dissipate the heat, thereby ensuring that the temperature of the heating body is uniform and avoiding safety accidents; at the same time, in the manufacturing process of the heating body, the copper tube can be clamped and fixed at the position of the notch 5 and then the aluminum substrate 1 is die-cast, so as to avoid direct die-casting of the copper tube in an unfixed state, which will cause the copper tube to shift and deform, and affect the heating efficiency of the heating body.

[0019] In the heating body of this embodiment, the flow channel protrusion 4 has a long straight section and a curved section, and each long straight section is provided with a notch 5.

[0020] Since the longer the runner tube 2, i.e. the copper tube, extends in the substrate 1, the higher the heating efficiency per unit time, the runner tube 2 is often bent to form multiple sections according to the size of the substrate 1. The more bends there are, the more difficult it is for the runner tube 2 to dissipate heat, and the runner tube 2 is more likely to swing, shift, and deform during the manufacturing process. Therefore, corresponding to each long straight section, a notch 5 is provided on the runner protrusion 4 of the substrate 1, so that the temperature of the entire heating body is relatively uniform, avoiding local temperature rise too fast and causing failure. At the same time, during the manufacturing process, the notches 5 at various locations can also more stably clamp and fix the runner tube 2 before processing the substrate 1, ensuring that the runner tube 2 is located in the middle of the substrate 1, thereby ensuring that the heat transferred to the runner tube 2 by the heating thick film 3 is uniform and stable.

[0021] In the heating body of this embodiment, each long straight section is provided with a plurality of notches 5 , and the plurality of notches 5 are arranged at intervals.

[0022] As described above, a plurality of notches 5 can improve the heat dissipation efficiency and facilitate processing and manufacturing.

[0023] In the heating body of this embodiment, the notch 5 is opened along the radial direction of the flow channel protrusion 4.

[0024] The notch 5 is provided along the radial direction of the flow channel protrusion 4 to increase the heat dissipation area and also facilitate the clamping and fixing of the flow channel tube 2 during the manufacturing process.

[0025] In the heating body of this embodiment, the notches 5 on different flow channel protrusions 4 are arranged at intervals and are not connected to each other.

[0026] In order to ensure the overall strength and heating efficiency of the substrate 1, the notches 5 of different flow channel protrusions 4 cannot be connected, so as to achieve a balance between heating efficiency and emergency heat dissipation.

[0027] A fixing member 6 is also disposed in the base plate 1 . The fixing member 6 is formed in a shape matching the flow channel tube 2 so as to be snap-connected with the flow channel tube 2 .

[0028] The fixing member 6 and the flow channel tube 2 are not only snap-fitted, but can also be welded to achieve a fixed connection, thereby preventing the flow channel tube 2 from shifting or deforming during the manufacturing process of the heating body.

[0029] The combined heating body includes any two heating bodies, and the two heating bodies are close together with one side facing away from the flow channel protrusion 4, wherein a sealing groove 7 is opened on the substrate 1 of any heating body, and the sealing groove 7 is located at the edge of the substrate 1 and is at least arranged around the lower part of the heating thick film 3, and a sealing ring 8 is arranged in the sealing groove 7, and the two substrates 1 clamp and press the sealing ring 8.

[0030] The sealing gasket can effectively prevent water from entering between the two heating bodies, and avoid the heating thick film 3 from contacting water and causing a short circuit, thereby greatly improving the safety and service life of the combined heating body.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
