AI Technical Summary
In the current PTC electric heater manufacturing process, the methods of fixing aluminum tubes and corrugated sheets have problems such as high cost, low thermal conductivity or low efficiency. In particular, the welding method affects the function of the PTC heating core, while the bonding method reduces thermal conductivity and is complicated to assemble.
Design a pressing mold for aluminum tubes of PTC electric heaters. The mold uses a base made of mold steel and insert teeth made of manganese steel. The insert teeth are designed with guide cone surfaces for insertion into the corrugated sheet grooves. The aluminum tube is pressed by a hydraulic press to achieve welding and fixing of the aluminum tube and the corrugated sheet, simplifying the processing procedure.
This method achieves tight fixing between the aluminum tube and the corrugated sheet, reduces production costs, improves thermal conductivity, simplifies the processing flow, avoids the influence of welding temperature on the PTC heating core, and improves processing efficiency.
