How to Choose the Right Heating Coil Component for Your Electronic Cigarette?

The heating coil is the core component of an electronic cigarette atomizer. Different heating coils are suitable for different output modes, such as power output and temperature control output, and there are also some heating coils that can be compatible with both output modes. Regardless of the material of the heating coil, they all have some basic features.

The diameter of the heating coil is the first characteristic of any heating coil, usually measured in gauge. In fact, the coil diameter is not a very important factor, but what's important is that as the gauge increases, the coil diameter becomes smaller. Therefore, compared to a 24ga heating coil, a 26ga heating coil is thinner, while a 28ga heating coil is thicker. Heating coils typically come in sizes of 32, 30, 28, 26, 24, and 22, as well as other specifications, and even odd-numbered sizes.

There are different types of heating coil components, including:

Riveted heating coil components;

Welded heating coil components;

Simple wire-wrapped heating coil components;

Spring coil (screw) heating coil components;

Ceramic core heating coil components;

Heating plate components.

1. Riveted Heating Wire Assembly

Application: Suitable for various small cigarettes, integrated cigarettes, and Tank atomizers.

Features:

Advantages: Firm structure, strong resistance to bending and folding, stable resistance value.

Disadvantages: The terminal takes up a certain amount of space, and the size needs to be considered during design.

2. Welded Heating Wire Assembly

Application: Suitable for various small cigarettes, integrated cigarettes, Tank atomizers, etc.

Features:

Advantages: Stable resistance, small tolerance, and small welding point occupation.

Disadvantages: When the diameter is less than or equal to 0.08 millimeters, welding is difficult, and the yield is low.

3. Simple coiled heating wire components and their material composition and application

This type of heating wire is widely used in various flat tobacco POD atomizers. Due to its simple structure, small size, stable resistance, and high production efficiency, it is suitable for small-sized flat tobacco PODs. However, the heating wire in this type of heating wire also serves as a conductive connection during heating, which will occupy a certain amount of power, so the product's structural design and accuracy requirements are higher.

4. Ceramic heating wire material composition and application

Ceramic core heating wire consists of a ceramic body, internal heating wire, pin connection wire, and some accessories that require electrodes. This type of heating wire can be used in small cigarette atomizers, Tank atomizers, box cigarette atomizers, etc. It has the characteristics of stable resistance, stable structure, and not easy to deform.

5. Spring coil heating wire material composition and application

The spring coil heating wire is made by welding, winding, and bending the heating wire and connecting wires. This type of heating wire is mostly used in high-power electronic cigarettes and is favored by DIY users. It has a small resistance and can be used in parallel. When used, it can be manually threaded with cotton rope or block-shaped cotton.

6. Material Composition of Heating Plate Heating Component

Stainless steel heating plate: It is composed of stainless steel substrate and pin connection wire, and is processed by stamping, rolling, seamless welding and other processes.

Thick film resistor: It is commonly used in instant heating equipment and is processed by stainless steel substrate through thick film process.

Application scenarios:

Stainless steel heating plate: Mostly used in high-power electronic cigarettes.

Thick film resistor heating plate: Mostly used for heating tobacco products.

Features:

Stainless steel heating plate: Small resistance, stable structure, not easily deformed.

Thick film resistor heating plate: Stable resistance, good heating effect, and long service life.

7. Key Parameters of E-cigarettes and their Impact on Performance

Resistance: affects the amount of smoke, start-up speed, taste and the number of puffs.

Material and specifications of the heating wire: affect start-up speed, taste, power output and production process.

Coil turns/pitch: affects the uniformity of heating, heating area, taste and assembly.

Fiberglass rope/cotton rope: affects taste, assembly and oil storage capacity.

Structural dimensions: affects structural design and assembly.

The selection of these parameters needs to meet the product requirements, but also needs to be determined through repeated validation, trial production, and comparison to find the heating wire components that are most suitable for the product. Different coil selections can have a significant impact on the user experience, and temperature control wire (except for stainless steel wire) can only be adapted to the host's temperature control mode. Therefore, we need to change the host's current, power, and output mode to adapt to different heating wire materials and specifications to achieve the best user experience. In addition, making coils with different turns and diameters can also bring us different user experiences. When we find the heating wire data that is suitable for a specific atomizer, we can record it for future reference.
