Brief Introduction

This PTC electric heater is suitable for electric/hybrid/fuel cell vehicles, mainly as the main heat source for in-vehicle temperature regulation. This PTC electric water  heater is suitable for both vehicle driving mode and parking mode. During the heating process, the electrical energy is effectively converted into thermal energy by the PTC component, so this product has a faster heating effect than the internal combustion engine. At the same time, it can also be used for battery temperature regulation (heating to operating temperature) and fuel cell starting load.
This PTC electric heater uses PTC technology to meet the safety requirements of passenger cars for high voltage. In addition, it can also meet the relevant environmental requirements of engine compartment components.
The purpose of the automotive Electric High Voltage PTC Heater in application is to replace the engine block as the main heat source.It is to supply power to the PTC heating group to make the PTC heating component heat up, and through heat exchange, heat the medium in the heating system circulation pipeline.
The main performance characteristics are as follows:
It has a compact structure, high power density, and can be flexibly adapted to the installation space of the entire vehicle.
Redundant sealing design can improve system reliability.
