The downstream industries of electric heating components mainly include civil, commercial, industrial, and new energy vehicles, with high standards for product iteration, application extension, and product response speed. To meet relevant requirements, the industry needs to focus on production technology level and R&D innovation. In terms of production, there are high requirements for production environment control, process flow, on-site management, and quality control; In terms of research and development innovation, it is necessary to carry out internal product innovation and cross variety and cross domain innovation to meet market demand.
1.The overall technical level of civil electric heating elements in the civil electric heating element industry is constantly updated and iterated with the changes in downstream consumer demand, and customization and safety directly reflect the current technical characteristics and requirements of the industry.
1). Customization: The continuous improvement of national economic fundamentals has driven consumers to shift from basic needs to high-quality needs. With the prevalence of lazy economy and leisure consumption, consumers have raised higher demands for the performance characteristics of household appliances. In order to meet consumer needs to a greater extent, electric heating component manufacturers usually adopt a customized cooperation model with downstream household appliance customers to improve product differentiation and meet the wishes of downstream consumers.
2). Safety: As the core indicator of household appliances, safety and reliability directly determine the customer satisfaction of electric heating components. In recent years, with the increasing demand for high-power and high current electric heating components, the insulation, voltage resistance, and current leakage prevention parameters of electric heating components have also significantly improved.
2. In the field of new energy vehicle heating, the mainstream battery heating methods in the new energy vehicle heating element industry are PTC, heat pump, and high-pressure liquid heating. High pressure liquid heating adopts the latest thick film electric heating technology. Compared with traditional PTC ceramic electric heating elements, the advantages of thick film electric heating elements are:
1). High power density: the power is nearly 10 times that of PTC electric heating elements;
2). Fast thermal response speed: The heating speed of the thick film resistor layer can reach 200-300 ℃/s;
3). The structure of the heating film is compact: the trajectory of the thick film can be designed with arbitrary graphics, avoiding the defect of heating blind spots in traditional electric heating devices;
4). Long service life: The theoretical service life can reach over 10000 hours, which is about 10 times that of PTC ceramic electric heating elements;
5). Excellent energy-saving performance: small thermal capacity, with a thermal efficiency of up to 85% -95%.
