This high voltage coolant heater contains self-control temperature PTC heater element, water and electricity separation, safe and reliable. It has a simple structure, high thermal efficiency, and achieves IP67 waterproof grade. It has small power aging and long service life. What's more, the PTC coolant heater has the technical parameters of high temperature resistance, cold resistance, corrosion resistance, vibration resistance and electromagnetic interference resistance. Cockpit heating is the most basic heating need, fuel cars and hybrids can get heat from the engine, the electric drive assembly of electric vehicles do not generate as much heat as the engine, so a PTC heater needs to be added to meet the winter heating needs. This PTC coolant heater is widely installed in the electric vehicle thermal management system because of its good heating effect, uniform heat dissipation distribution, safety and reliability, etc.
