Problems solved by technology

[0005] The efficiency of the above process or technology is low, the power consumption is large during the curing process, and the consistency of the product is poor. It is unavoidable to avoid the occurrence of unqualified products due to human operation errors and the unqualified rate is also high. After curing, it is necessary to conduct power-on or high-voltage tests.
In particular, manually aligning the head and end of the heating element will inevitably lead to errors that cause the two sides of the product to be non-parallel, and the process of knocking out the corrugated heating surface of the heater also leads to loosening of the heating element inside the aluminum tube. A little negligence will lead to uneven or skewed heat dissipation ripple heating surface of the heater, which will affect the appearance and assembly, resulting in scrap
[0006] Chinese patent 2014107228663 discloses a solidified pressure-resistant detection device for the heating core of an air conditioner, which only solves the material problem of the operating table, and does not provide a technical solution superior to the traditional technology on how to fix the PTC heating device
