AI Technical Summary

Problems solved by technology

However, there are many deficiencies in the above-mentioned prior art: the heat emitted by the heating module needs to be transferred to the heat transfer medium, but there are too many intermediate links in the heat transfer process (such as metal belts or metal bases), resulting in relatively low heat transfer resistance. Large, low heating power per unit volume, and intermediate links such as metal strips are usually made of expensive special alloys, resulting in high product costs

Embodiment 1

[0052] This embodiment provides a figure 2 The electric heating element 11 shown is used for electric heating elements of civil electric water heaters, civilian air-conditioning electric heaters, and vehicle electric heaters. The electric heating element 11 includes an aluminum flat tube 113, and is arranged in the aluminum flat tube 113 At least one electrode strip assembly, the outside of the electrode strip assembly is an insulating wrapping layer, and the inside of the electrode strip assembly includes at least one electrode stacked by positive electrode strips, PTC ceramic sheets, and negative electrode strips.

[0053] Wherein the aluminum flat tube can also be replaced by other metal flat tubes.

[0054] One end of the electric heating element 11 is provided with a positive terminal 111 and a negative terminal 112, the positive terminal 111 is connected to the positive electrode strip, and the negative terminal 112 is connected to the negative electrode strip.
