In-line heater design and optimization

The shell of the online heater is the supporting structure and protective layer of the equipment, which protects the internal heating elements and other sensitive components from the damage of the external environment. The shell also provides electrical isolation and thermal insulation of the equipment against leakage of current and heat. Therefore, the importance of the shell lies in its protection and isolation function, as well as in ensuring the safe and stable operation of the equipment.


The heating element is the core component of the online heater, which is directly involved in the production and transfer of heat. The performance and efficiency of the heating element directly affect the heating effect and energy consumption of the equipment. If the heating element is problems, such as uneven heating or low heating efficiency, the performance or damage of the equipment. Therefore, from the perspective of the use of function, the heating element is more important than the shell.


However, in some cases, the interactions between the shell and the heating element may also have important effects on the performance of the device. For example, the design and structure of the shell may affect the performance and heat dissipation effect of the heating element. Therefore, the shell and heating elements need to be comprehensively considered and optimized when designing and manufacturing the on-line heaters.


For these characteristics, Warinkner has made an optimized design for the online heater from the following four aspects.


1. Material selection and optimization

High quality PFA material ensures excellent heat resistance, chemical stability and electrical insulation properties.

High strength imported nickel chromium with gold wire, improve the mechanical properties, corrosion resistance and electrical properties of heating wire.


2. Improve the heating efficiency and uniformity

The structure of the on-line heater is optimized to effectively improve the heating efficiency and uniformity. For example, ensure the reasonable design of the distribution and shape of the heating elements, and ensure that the heat can be distributed more evenly throughout the heater surface.


3. Long-life and reliability design

Strictly control the temperature, pressure, speed and other key process parameters in the processing process to ensure the uniformity, compactness and attachment of the outsourced PFA resin, so as to obtain excellent heat resistance, chemical stability and electrical insulation performance, so as to ensure the service life of the heating wire.


4. Intelligent control and fault diagnosis, etc.

The temperature sensor monitors the temperature of the heating wire in real time to provide data support for the intelligent control.


The own chip control system (heating protection, outlet temperature control, 485 communication) can reduce the permanent damage to the heater due to various improper operations.
