Advantages of stainless steel thick film heaters

1. High efficiency
High power density: The power density of stainless steel substrate high power density thick film electric heating elements can reach up to 60-100W/cm² (primary heat exchange structure), while the traditional electric heating alloy is only 20W/cm², which means that under the same unit area, stainless steel thick film heaters can generate more heat, heat faster, and quickly reach the required temperature. For example, in some instant hot water dispensers, electric water faucets and other products, it is necessary to heat water to a suitable temperature in a short time, and the high power density of stainless steel thick film heaters can meet the needs well. Its high power density allows it to reach a temperature rise of 200/S under high power conditions. In addition, the thermal efficiency is very high, reaching more than 97%. For example, when heating a cup of 250ml of water, it only takes 20 seconds, which is much lower than the 60-second heating time of traditional heaters. This fast heating capability is very advantageous in many scenarios that require heating speed, such as coffee brewing equipment, instant hot water dispensers, etc.

High heating speed and fast temperature rise: This feature is closely related to the characteristics of high power density. High heating speed means fast response, which can start to generate heat in a short time and quickly increase the temperature of the heated object. In some application scenarios with high immediacy requirements, such as instant hot water purifiers and instant hot faucets, this product can quickly raise the water temperature to meet user needs after it is turned on.

2. Physical properties
High mechanical strength: Stainless steel thick film heaters have strong resistance to vibration and thermal shock, and will not have the problem of traditional electric heating alloys becoming brittle under high temperature conditions. For example, when used in some equipment in motion or in scenarios where the ambient temperature changes frequently (such as the heating elements used in the interior of the car need to cope with vibrations during driving and temperature changes under different meteorological conditions), it can work stably and continuously, and its working stability is high. In some instruments and equipment that require high component stability, this feature can also ensure that the heater is not easily damaged by external factors, ensuring normal use and normal operation of the instrument and equipment.

Advantages of component shape: The component is thin and flat, and can also be made into a curved surface, which is small in size and easy to install. This thin plane feature is very suitable for equipment with strict space requirements, such as some compact home appliances, such as small rice cookers, portable electric heating equipment, etc. The heater can be arranged in a limited space, and the curved surface shape enables it to adapt to the appearance requirements of different equipment, such as being able to fit some heating containers with special shapes to ensure uniform heating. This flexibility and compactness are difficult to achieve with traditional heaters. Moreover, due to its small size, it is very convenient in controlling the overall volume of the equipment and the industrial design layout, making the product lighter, smaller and more delicate.

The power of the heating element is easy to differentiate: This means that the power of the heating element can be accurately adjusted according to different needs. For example, some experimental instruments and equipment that require precise control of the heating temperature and heat, or in some home appliances that require different heating power gears (such as products such as kettles with multiple temperature settings), it is easy to achieve flexible settings of the heating function, thereby improving the convenience of product use and the rationality of energy utilization, and avoiding the problem of excessive or low power affecting the user experience or heating efficiency.

3. Energy saving and environmental protection
Good energy-saving performance: Since the heating body adopts screen printing technology, the volume of the heating body is basically negligible, and the fast temperature rise rate saves 10-25% energy compared with traditional electric heating elements (depending on the product structure). In large-scale industrial heating or home and commercial environments where electric heating equipment is used in large quantities on a daily basis, this energy-saving effect can effectively reduce energy consumption and reduce energy costs. For example, in a large office building, a large number of water dispensers, instant water heaters and other equipment containing stainless steel thick film heaters are used. The energy-saving effect is obvious in the long run, which meets the urgent needs of modern society for energy conservation and emission reduction.

Outstanding environmental protection concept: It does not produce aluminum ions that may cause senile dementia, and meets environmental protection requirements. In various usage scenarios, whether it is home or industry, the use of heating elements will not produce substances harmful to human health, nor will it cause harmful effects such as aluminum pollution to the environment, which is conducive to creating a healthy and environmentally friendly use environment, especially when it comes to heating equipment related to food, drinking water, etc. (such as water dispensers, coffee machines, etc.). This feature is particularly important.

4. Service life
Long service life: Due to the use of hybrid microelectronics technology, the service life is longer than that of traditional Joule heating elements. Generally, the product can work continuously for more than 10,000 hours. For example, in some equipment that requires stable heating functions for a long time, such as auxiliary heating equipment for air conditioners, some constant temperature heating instruments for industrial use, etc., there is no need to frequently replace the heating elements, thereby reducing the maintenance cost of the equipment, ensuring the long-term stable operation of the equipment, and improving the overall reliability of the equipment. Its long service life is also of positive significance for reducing the generation of electronic waste.

5. Safety and security
High safety factor: Stainless steel thick film heating belongs to surface heating, and the overall heating is relatively uniform. The heating efficiency will not be reduced due to a large number of bubbles on the surface of the heater. Since the heat can be conducted away in time, the surface temperature of the entire heating tube is not high and will not cause open flames. In addition, thick film heaters are mostly started at a lower voltage when working, which is safe. Furthermore, five layers of insulation are printed during the production process, with a voltage resistance of over 1500V, which greatly enhances safety during use. It can effectively avoid the risk of electric shock caused by safety hazards such as leakage, and provide reliable safety protection for users and equipment in various application scenarios such as household appliances and instruments.
