Abstract

The invention provides an optical fiber welding type PTC water heater with a controller. The water heater comprises an upper shell and a lower shell, wherein the upper shell and the lower shell form an outer shell; the controller is arranged in the upper shell, electrodes are arranged in the upper shell and the lower shell, a heating core body is arranged in the lower shell, the electrodes penetrate through the lower end of the upper shell and the upper end of the lower shell and then penetrate into the heating core body, a heat dissipation plate is arranged at the lower end of the heating core body, and a low-voltage connector and a high-voltage connector are arranged on the controller. Through the controller, the PWM adjustment control is implemented for controlling the increase or decrease of the duty ratio and achieving the stepless adjustment of heating power of the PTC water heater. In addition, network management, communication fault diagnosis and online flashing functions basedon UDS are added, and the technical problems that an existing new energy automobile heating device is poor in effect, low in efficiency, large in size and large in electric energy consumption are solved.

Description

technical field [0001] The invention relates to the field of PTC heaters, in particular to an optical fiber welding type PTC water heater with a controller. Background technique [0002] At present, when adjusting the temperature of electric vehicles, PTC devices are generally used to adjust the vehicle temperature, and the current PTC water heating heaters generally have the following three structures: PTC cast aluminum structure, heating film structure and PTC harmonica tube brazing structure However, there are problems in the above three structures. The PTC cast aluminum structure is relatively heavy and bulky due to the influence of the process; the heating film structure will cause the heating film to be easily pierced, withstand voltage differences, and the temperature is easy to get out of control, and there is a risk of leakage and fire; the harmonica tube Since the brazing structure is not integrated with the harmonica tube and the heating core, the heat exchange ef...
