[0020] Example 1

[0021] Reference Figure 3 This utility model provides a heating assembly, including: a flange 1, at least one heating tube 2, and a terminal block 3. The flange 1 has multiple wiring holes (not shown in the figure); the two ends of the heating tube 2 are inserted and welded to different wiring holes (not shown in the figure), and the two ends of the heating tube 2 are fixedly connected to the terminal block 3. An aluminum tube 4 is sleeved on the outer periphery of the heating tube 2. The thickness of the aluminum tube 4 is 0.5mm to 4mm. The aluminum tube 4 is fixedly sleeved on the outside of the heating tube 2 by a tube shrinking process.

[0022] The specific production process of the heating component is as follows: First, aluminum tube 4 is sleeved on the outside of heating tube 2. Then, aluminum tube 4 is shrunk by a tube shrinking machine so that aluminum tube 4 is tightly attached and fixed to the outside of heating tube 2. Then, aluminum tube 4 and heating tube 2 are bent together to form heating tube 2 of a specific shape. Then, the two ends of heating tube 2 are welded to flange 1, and wiring terminals 3 are welded to the two ends of heating tube 2.

[0023] By using a tube-shrinking process to sleeve and fix the aluminum tube 4 onto the outside of the heating tube 2, the corrosion resistance and service life of the heating tube 2 can be effectively improved, while also providing high structural strength and resistance to breakage. Furthermore, the aluminum tube 4, with a thickness of 0.5mm to 4mm, facilitates the tube-shrinking process and allows for subsequent bending and shaping along with the heating tube 2. This tube-shrinking process effectively simplifies the production process and reduces production costs. This heating assembly exhibits good anti-scaling properties and resistance to corrosion from acidic, alkaline, and saline environments, while the sleeved aluminum tube 4 increases the heat dissipation area of ​​the heating tube and extends its service life.

[0024] In this embodiment, the aluminum tube 4 has a thickness of 1mm. The function of the aluminum tube 4 in this design is to isolate water from the heating tube 2. By limiting the aluminum tube 4 to a relatively thin 1mm thickness, this embodiment effectively controls production costs and reduces the weight of the heating component while ensuring basic insulation functionality. It does not affect the bending and shaping process of the heating tube 2, and the aluminum tube 4 also possesses a certain structural strength, making it less prone to puncture from impacts.

[0025] Furthermore, an epoxy resin layer 11 is provided on the side of the flange 1 near the heating pipe 2, and the epoxy resin layer 11 covers the connection between the heating pipe 2 and the flange 1. By adding the epoxy resin layer 11, it can be used to isolate the welded joint between the heating pipe 2 and the flange 1 from water, prevent water from corroding the welded part, and ensure the service life of the heating assembly.

[0026] Furthermore, the heating assembly also includes a temperature sensing tube 5. A temperature sensing hole is provided on the flange 1. One end of the temperature sensing tube 5 is closed, and the other end passes through and is welded to the temperature sensing hole. The epoxy resin layer 11 covers the connection between the temperature sensing tube 5 and the flange 1. By providing the temperature sensing tube 5, a temperature sensor can be installed to monitor the temperature inside the water heater in real time.

[0027] Example 2

[0028] Please refer to Figures 1-2. The difference between this embodiment and Embodiment 1 is that this embodiment does not include a temperature measuring tube 5, and the heating tubes 2 are arranged in three sets, with the three sets of heating tubes 2 arranged side by side and spaced apart. By setting three sets of heating tubes 2 to work simultaneously, the heating efficiency can be effectively improved, and the side-by-side spacing ensures that the heating component has a relatively regular shape, which is convenient for installation.

[0029] Furthermore, the heating assembly also includes at least one pipe clamp 41, wherein one end of the pipe clamp 41 is fixed to the flange of the heater, and the other end fixes the position of the three sets of aluminum tubes 4. By adding the pipe clamp 41, the position of the heating assembly can be fixed, further improving the stability of the heating assembly during use. The pipe clamp 41 is a stainless steel pipe clamp. (See attached image) Figure 1 In the drawing, the pipe clamp 41 is abbreviated, only the clamp head is shown, and the connecting rod connecting the clamp head and the inner liner is not shown.

[0030] This utility model embodiment also provides a water heater, including an inner tank and a heating component as described above, wherein the heating component is installed at an opening at one end of the inner tank. The heating component uses a tube-shrinking process to sleeve and fix an aluminum tube 4 to the outside of the heating tube 2, which effectively improves the corrosion resistance and service life of the heating tube 2, while also providing high structural strength and resistance to breakage. Furthermore, the aluminum tube 4 has a thickness of 0.5mm to 4mm, facilitating the tube-shrinking process and subsequent bending and shaping along with the heating tube 2. This tube-shrinking process effectively simplifies the production process and reduces production costs. This heating component exhibits superior anti-scaling properties and resistance to corrosion from acidic, alkaline, and saline water conditions. The sleeved aluminum tube 4 increases the heat dissipation area of ​​the heating element and extends its service life.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
