Thick Film Heaters Introduction:
The typical base material for a Thick Film element is stainless steel substrate, which is coated with a glass-ceramic enamel for electrical insulation. Heating tracks are then screen printed onto the insulated surface. Finally, a protective enamel layer is applied, leaving designated areas exposed for electrical connections.
Their compact and durable design makes them ideal for various applications, including household appliances, medical devices, automotive systems, industrial equipment, consumer electronics, HVAC systems, and food service equipment. The key benefits of thick film heaters include fast and uniform heat distribution, long lifespan, and safety, making them a reliable choice for modern heating needs.
Technical Parameters:
1.The Thick film heater is suitable for two dimensional shapes and tubes.
2.Track layouts can be customized with different heating zones
3.NTC sensor can be integrated to detect temperature variations through resistance changes.
4.The substrate is stainless steel (typically), ceramic is also can be used.
5.The assembly methods include soldering to metal containers or brazing to component substrates.
6.The life of Thick Film Heating Elements are up to 10,000 hours above.
Applications:
1. Coffee machine (This switch from a thermal block to a flow-through heater in a coffee machine allows both hot water and steam from one heating system, simplifying the appliance. It also enables rapid temperature changes for perfect brewing of different teas per cup. With a good design, the additional benefits can be significant.)
2. Instant hot water dispenser
3. Thick film heater for Steam Irons.
4. Thick film heater for dishwasher
Q1: What are the substrates for thick film heaters?
A: The standard substrate is stainless steel 304 or 430, and ceramic is also an option.
Q2: Can the shape of a thick film heater be customized?
A: Yes, shapes can be two dimensional shapes, or three dimensional shapes can be customized, such as tubes.
Q3: Can a thick film heater design have different temperature zones？
A: Yes, different power densities can be designed to control various temperatures, enabling high, medium, and low temperature zones.
Q4: Can a thick film heater be integrated sensors?
A: Yes, sensors can be integrated, such as NTC, which can sense the temperature based on resistance.
Q5: What are the assembly methods for thick film heaters?
A: It can be encased in a plastic molding, welded into a metal vessel, or brazed to the element substrate.
Q6: How to choose the voltage of Thick film heater?
A: AC and DC voltage sources are available.
Q7: How to do the surface mount sensors and thermostats?
A: Printed RTDs or surface-mount thermistors on heaters directly, they are utilized for immediate, on-board temperature feedback and control, as well as enabling the assembly of more intricate heater systems.
Q8: What products are thick film heaters used for?
A: DNA Analysis and Testing, Blood Diagnostics, Surgical Devices, 3D printer, laser printer, heated dishware, explosives detection, water heating and so on.
Q9: What advantage does low mass offer in terms of temperature control?
A: Low mass facilitates fast temperature ramp up and cool down.
Q10: Why is a glass-ceramic necessary for thick film heaters?
A: A glass-ceramic is necessary for Thick Film Heaters because it serves as both an electrical insulation and a substrate to carry the printed (conductive) heater tracks. This insulation prevents electrical shorts and ensures efficient heat transfer to the desired areas.
