Description

Technical Field

[0001] This utility model relates to the field of aluminum foil heater technology, and in particular to an aluminum foil heater assembly. Background Technology

[0002] Aluminum foil heaters play a crucial role in the temperature control system of refrigerators. They are used in the defrosting function to prevent excessive frost buildup on the evaporator surface inside the refrigerator, which would affect cooling efficiency. They also function in the low-temperature compensation system of some refrigerators, ensuring that the refrigerator can start the refrigeration cycle normally and maintain a stable internal temperature in low-temperature environments.

[0003] However, traditional aluminum foil heaters for refrigerators have some structural defects. Because refrigerators undergo frequent opening and closing during daily use, this causes changes in internal temperature and pressure, resulting in airflow fluctuations and mechanical vibrations. Due to the material properties of aluminum foil heaters, which are relatively thin and flexible, their outer surface is prone to deformation, wrinkles, or even localized damage under such long-term vibration and airflow impact.

[0004] As consumers increasingly demand higher quality and reliability from refrigerators, and with the home appliance industry becoming increasingly competitive, manufacturers urgently need to improve the structural design of aluminum foil heaters for refrigerators to enhance the strength and stability of their outer surface, improve their durability and safety, and ensure that refrigerators can operate stably and efficiently during long-term use.
