PTC heater

Abstract

The invention provides a PTC heater. The PTC heater comprises a shell; a left side mounting end is arranged in the shell; a mounting hole is formed in the left side mounting end; a left supporting base is arranged at one end, provided with the left side mounting end, of the shell; a radiating layer is arranged in the shell; S-shaped radiating bars are arranged in the radiating layer; an aluminumtube is further arranged in the shell; the aluminum tube is provided with multiple PTC elements and multiple electrode strips; an insulating layer is arranged between the aluminum tube and the radiating layer; a right supporting base is arranged in shell at the right ends of the radiating layer and the aluminum tube; a temperature controller and a fuse are arranged in the right supporting base; a thermal shrinkage protection sleeve is arranged on the shell at one end of the right supporting base; the right supporting base and the left supporting base are both fixed with the shell through self-tapping screws; and the aluminum tube is fixed with the right supporting base and the left side mounting end through silica gel cushions. The PTC heater is simple in structure, reasonable in design, low in cost, relatively high in insulation property and fixation property as well as capable of automatically monitoring the internal temperature of the heater.

Description

technical field [0001] The invention relates to the field of heater production, in particular to a PTC heater. Background technique [0002] The use of PTC heaters is becoming more and more common. It has the advantages of small size, rapid heat generation, large heat generation and less energy consumption. It will cause internal structure aging during long-term use, and long-term high temperature will cause internal components damage, and the internal structure is prone to loosening, and long-term use will cause safety hazards. Contents of the invention [0003] In order to solve the above problems, the present invention provides a PTC heater that can automatically cut off the power supply when the temperature is too high, and has strong insulation and fixability. [0004] In order to achieve the above object, the present invention is achieved through the following technical solutions: [0005] The present invention is a kind of PTC heater, comprises shell, is provided ...
