Description

Technical Field

[0001] This utility model belongs to the technical field of electric heating equipment, and specifically relates to a heating element for an electric heater. Background Technology

[0002] Traditional ceramic PTC heaters mainly use ceramic substrate heating elements as the core. The material is relatively fragile and easily damaged by physical impact. Under extreme temperature or humidity conditions, its performance may be affected. After long-term use, power may decrease, leading to increased energy consumption. In addition, it does not have the flexibility of alloy heating wires, so it cannot be bent at will, nor can it be made into a single long heating element as needed. Larger power usually requires several ceramic PTC heating elements to be connected in parallel. Furthermore, fixing these ceramic PTCs and conducting heat to the outer surface is also subject to structural constraints. Utility Model Content

The material and shape of the heating wire 300 are determined according to specific requirements and can be straight, spiral, or other shapes to optimize heating effect and power distribution.

[0041] One end of the lead rod 500 is connected to the heating wire 300, and the other end extends outward from the housing 100 through the plug 200 for connecting to an external power source. The lead rod 500 is typically made of a material with good electrical conductivity, such as a copper or silver alloy, to ensure efficient and stable current transmission.

[0042] A heat dissipation component 400 is disposed on the outer surface of the housing 100 to dissipate heat generated during the heating process into the environment.

[0050] In this embodiment, when both ends of the housing 100 are provided with openings, the input rod 501 and the output rod 502 extend outward from the housing 100 through the plugs 200 at both ends, respectively. This design allows the heating element to be installed and used more flexibly.
