Abstract

The invention discloses a manufacturing process of a metal surface thick-film heater. The manufacturing process comprises the following steps of 1, selecting a metal surface thick-film heater base material; 2, treating a metal surface; 3, printing and sintering an insulating layer 2; 4, printing and sintering a conductive layer; 5, printing and sintering a resistance layer 4; 6, printing and sintering a protective layer; 7, cutting the heater; and 8, performing laser code spraying. According to the invention, a metal substrate is coated with the insulating layer; the insulating layer is coatedwith the conductive layer; the conductive layer is coated with the resistance layer to serve as a heating medium, and finally, the resistance layer is coated with the protective layer to prevent accidental collision and the scratching of film layers of the thick-film heater such that all the film layers are closely fused into a whole, all the layers are closely fused into a whole, and the problems of low efficiency, high power consumption, short service life, high cost and the like of the thick-film heater are solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing of metal surface thick film heaters, in particular to a manufacturing process of metal surface thick film heaters. Background technique [0002] A heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, high in heating power, widely used, adopts intelligent control mode, has high temperature control accuracy, and can be networked with computers. Wide application range, long life and high reliability. The core of the heater principle is energy conversion, and the most extensive is the conversion of electrical energy into thermal energy. [0003] Traditional thick film heaters have low power density, small heat exchange area, low thermal efficiency and high power consumption. For this reason, we propose a manufacturing process for metal surface thick film heaters. SUMMARY OF THE INVENTION [0004] The purpose of the present invention...
