In the design and manufacturing process of heated water cups, the heating tube is a key component, which is responsible for providing the heating function. Different types of heating tubes have their own characteristics and scope of application. This article will detail several common heating tube types.
1. Electric heating wire heating tube:
Electric heating wire heating tube is a common and economical and practical heating element. It is made of high-resistance alloy wire surrounded by thermally conductive or insulating material. When energized, the electric heating wire generates heat and transfers the heat to the heated water cup through conduction and convection. Electric heating wire heating tubes have the advantages of simple structure and low manufacturing cost, but the heating speed is slow and the temperature distribution is uneven.
2. PTC heating tube:
PTC (Positive Temperature Coefficient) heating tubes are another common heating element. It is made of PTC material, which has the characteristic that the resistivity increases with temperature within a certain temperature range. When current passes through the PTC heating tube, the temperature rises and the resistivity increases, thereby restricting the flow of current and generating heat. The PTC heating tube has a self-temperature function, which can maintain a relatively stable heating temperature within a certain range and is safe and reliable.
3. Ceramic heating tube:
Ceramic heating tubes are usually made of ceramic materials and have good high temperature resistance and thermal conductivity. The ceramic heating tube uses a resistance wire or heating element embedded in the ceramic tube to transfer heat to the water cup through thermal conduction. Ceramic heating tubes have fast heating speed and high heating efficiency, and can provide uniform heating distribution.
4. Quartz tube heating tube:
The quartz tube heating tube uses a quartz glass tube as the outer shell, with a resistance wire or heating element embedded inside. Quartz tube has excellent high temperature resistance and thermal conductivity, and can transfer heat quickly. The quartz tube heating tube has a fast heating speed and can provide a uniform heating effect, which is suitable for rapid heating and heat preservation needs.
5. Metal tube heating tube:
Metal tube heating tubes use metal tubes as the outer shell, with resistance wires or heating elements embedded inside. #水杯#Metal tube has good thermal conductivity and can provide high heating efficiency. Metal tube heating tubes are suitable for high-power and large-capacity heating needs, but because the metal tubes are directly exposed to the external environment, attention must be paid to insulation and safety protection.
To sum up, the different types of heating tubes commonly used in water heating cups include electric heating wire heating tubes, PTC heating tubes, ceramic heating tubes, quartz tube heating tubes, metal tube heating tubes, etc. The production of heated water cups should be based on functional parameters and usage. Requires selection of different heating tubes.
