Core Differences Between Armored Heaters and Ordinary Heaters

Armored Heaters differ significantly from ordinary heaters in design philosophy and technological implementation, both structurally and in performance. The following is a detailed analysis of their core differences:

1. Structural Protection and Mechanical Strength

Armored Structure Design: Armored Heaters use a metal shell (usually stainless steel or aluminum alloy) to encase the heating element. This "armor" structure gives the product extremely high mechanical strength and impact resistance, capable of withstanding external physical impacts and compression.

Ordinary Heaters: Ordinary heaters (such as exposed heating tubes or heating films) typically lack an external metal protective shell, directly exposed to the environment, making them susceptible to physical damage from the external environment or human interference, resulting in relatively lower safety.

2. Heating Efficiency and Heat Conduction Methods

Uniform Radiant Heating: The interior of the armored heater is filled with insulating materials with excellent thermal conductivity (such as crystalline magnesium oxide powder). Heat is evenly diffused to the outer wall of the metal tube through the thermally conductive powder, and then transferred to the heated object through radiation, convection, and conduction. This design ensures extremely uniform heat distribution, preventing the formation of hot spots.

Ordinary Heaters: Ordinary heaters typically transfer heat directly from the heating element, resulting in uneven heat distribution. This can lead to uneven heating or excessively high surface temperatures, posing a risk of burns.

3. Lifespan and Safety

Long Lifespan and Safety: Armored heaters, thanks to their protective outer shell and high-quality insulation materials, have an extremely long service life. Their outer shell effectively prevents moisture intrusion, avoiding electrical failures caused by insulation aging. Furthermore, armored heaters do not glow red-hot during operation, eliminating the risk of open flames and significantly reducing fire hazards.

Ordinary Heaters: Lacking effective protective measures, the durability of ordinary heaters is limited by the aging of the heating element and corrosion from the external environment. Under high-temperature conditions, they are prone to accidents due to the outer shell melting or damage.

4. Applicability and Flexibility

Suitable for Harsh Environments: The outer shell of armored heaters can withstand high temperatures, high pressures, strong corrosion, and severe vibrations, making them suitable for extreme industrial environments such as aerospace, nuclear power, and petrochemicals.

Conventional Heaters: Conventional heaters are more suitable for household or general industrial environments. Their performance and safety may be insufficient when facing highly corrosive media or extreme temperatures.
