Description

Low-power efficient heat-collecting PTC heater structure Technical Field The utility model relates to the technical field of PTC heaters, in particular to a low-power efficient heat-collecting type PTC heater structure. Background The low-power high-efficiency heat-collecting PTC heater is a heater using Positive Temperature Coefficient (PTC) material, and the PTC material is characterized in that when the temperature is raised, the resistance value of the PTC material is increased, so that the PTC material has self-limiting temperature characteristic. The existing low-power efficient heat-collecting PTC heater is generally composed of a heating sheet, a shell and a power supply connecting wire, the PTC heating sheet is generally integrally formed with the shell in design, the integral design is mainly used for avoiding poor contact or looseness between components and improving the reliability and stability of equipment, however, the design also brings inconvenience in maintenance, if the heating sheet is damaged, maintenance personnel usually need to replace the whole PTC heater or disassemble the damaged shell to repair the PTC heater, so that the maintenance time and labor intensity are increased, unnecessary resource waste can be caused, and other parts are still intact because in actual maintenance, the integral structure is designed to improve the integral stability of the equipment in initial use, but the maintenance cost and the workload are high when the equipment breaks down, the maintenance is not efficient enough, and unnecessary material waste can be caused.
