Description
The concept of thick film is mainly in contrast to thin film. A thick film refers to a film layer with a thickness ranging from several micrometers to several tens of micrometers formed on a substrate through printing and sintering technology. The material used to manufacture this film layer is called thick film material. Thick film heating elements have numerous advantages such as high power density, fast heating speed, high working temperature, fast temperature rise rate, high mechanical strength, small volume, easy installation, uniform heating temperature field, long service life, energy conservation and environmental protection, and safety.
It has received extensive attention and application in various industries both at home and abroad. The traditional heating methods are gradually being replaced.
Thick film heating heater is becoming increasingly popular for heating water. Due to the low thermal mass of the thick film heating elements, almost all the generated heat is dissipated into the water. This low thermal mass also means that the energy is transferred to the water almost immediately after the power is turned on.
This is particularly important when heating small volumes, such as a single cup of water. In this era that values energy conservation, we can save water and energy by heating only what we need instead of heating the minimum amount required by the medium. This leads to extremely high efficiency. The energy is injected into the water almost immediately after the power is turned on. The floor heating must first heat itself and then inject the energy into the water.
More complex temperature control can be achieved through electronic devices. For example, you can select the desired temperature, then turn it on or off and cook. First bring to a boil, then cook at the pre-selected temperature.
On a disc with a diameter of 120 millimeters, the rated power can reach 3.1 kilowatts. And different diameters and designs can be customized according to the requirements of the equipment.
The thick film heater for water kettle is provided by us as fully tested heating modules, including printed heaters, safety controls and electrical connections. This reduces the assembly complexity and time for water kettle OEMs. The shape of the heater is not limited to a disc, which gives industrial designers greater freedom in design.
Attentions
Due to the large working current of the thick-film heating element, the electrical contact points are also a weak component of the heating element. Under the influence of factors such as alternating temperature and humidity in the working environment , it is prone to cause oxidation, heating and burnout of the contact points. Usually, in the design, the thickness and area of the thick-film conductor material should leave some margin. The thickness of the contact point and the silver content need to meet the actual usage requirements. Moreover, the elastic connection between the contact point and the thick-film conductor is generally combined with spring material, and beryllium bronze is usually selected as the best option because it has good elasticity and electrical properties.
