AI Technical Summary
Existing irregularly shaped PTC heaters are difficult to manufacture, require high processing precision, have high production costs, and have complex structures.
The corrugated heat sink is directly bonded to the PTC heating element, and the conduction is achieved through the corrugated heat sink, which simplifies the structure. Aluminum sheets are bent to form heat sinks of various shapes, and the connecting side plate is used as an electrode plate, which reduces production costs and improves efficiency.
The structure of the PTC heater has been simplified, production costs have been reduced, production efficiency has been improved, and the manufacturing difficulties of irregularly shaped PTC heaters have been solved.
