1. Product introduction
1.1 Product overview
PTC water heating heater can provide heat for the new energy vehicle cockpit and meet the standards of safe defrosting and defogging. At the same time, it provides heat to other vehicles that require temperature adjustment (such as batteries).
Electricity is used to heat the antifreeze, and the heater is used to heat the interior of the car. Installed in the water cooling circulation system
Warm air and temperature controllable
Use PWM to adjust the drive IGBT to adjust the power with short-term heat storage function
Whole vehicle cycle, supporting battery thermal management and environmental protection

The PTC water heater is an electric heater that uses electricity as an energy source to heat the
antifreeze and provide a heat source for the passenger car.
The heating device uses PTC semiconductor (positive temperature coefficient thermistor), and
the shell uses aluminum alloy precision casting, which has excellent anti-dry burning, antiinterference, anti-collision, explosion-proof performance, safe and reliable, and trustworthy.
