Materials and Processes: Cost Reduction and Efficiency Enhancement
First, within the framework of ensuring durability, explore the use of low-cost composite materials (such as galvanized steel and aluminum tube composites) to replace some stainless steel. Second, optimize the pipe wall thickness and fin structure, achieving lightweight design to reduce material usage while enhancing heat conduction efficiency. Third, upgrade the high-stability insulation coating (such as nano-ceramic coating), which must meet the strict electrical safety requirements of flammable refrigerants like R600a and also prevent corrosion to extend the lifespan.
Structure and Design: Precision and Integration
For the defrost heater, the heat distribution in different zones can be designed based on the characteristics of the evaporator airflow to prevent insufficient defrosting in cold areas and power waste in hot areas. For the dew prevention pipe, the thermal field simulation at the door frame can be optimized, and only the areas prone to condensation are arranged, eliminating ineffective heating. In the long term, the heater can be integrated with the evaporator or the air duct as a whole, transforming from an independent component to a functional module, reducing assembly processes.
Control and Energy Efficiency: Intelligence and Adaptability
The core lies in enabling the heater to abandon the “fixed-time, fixed-power heating” mode and integrating into the intelligent control system of the refrigerator. It operates intermittently or with variable power based on the ambient temperature, humidity, and frost accumulation. At the same time, to accommodate new types of flammable refrigerants like R290, it is necessary to enhance the explosion-proof and insulation design at the connection points to ensure that the heater does not pose a safety hazard in harsh environments.
Manufacturing and Quality Control: Automation and Traceability
By using fully automated production lines (such as bending, welding, powder filling), product consistency is ensured. A quality traceability system based on the Internet of Things is established, recording data throughout the process from raw materials to finished products, thereby enhancing reliability.
