6KW 350V High Voltage Coolant Heater for Electric Vehicle
Description
The PTC water heater heats the entire vehicle, provides heat to the cockpit of the new energy vehicle and meets the criteria for safe defrosting and defogging. The PTC liquid heater can also heat other mechanisms of the vehicle that require temperature regulation (e.g. the battery). The PTC coolant heater works by electrically heating the antifreeze so that it is heated internally by a warm air core. The PTC heater is installed in a water-cooled circulation system where the temperature of the warm air is gentle and controllable. The PTC heater drives IGBTs with PWM regulation to regulate the power and has a short time heat storage function. The PTC heater is environmentally friendly and energy efficient, in line with the environmental sustainability of today's times.

Function Description
The PTC coolant heater is designed to meet the voltage requirements of 350V, the PTC sheet is 3.5mm thick and Tc210°C to ensure good voltage resistance and durability. The internal heating core component of the product is in 4 groups and is controlled by 4 IGBTs. In order to ensure the product's protection level IP67, the product heating core component is fitted into the lower base, where it is sealed with potting glue and potted to the upper surface of the D-tube. After assembling the other components, a gasket is used to seal between the upper and lower bases to ensure that the product is waterproof.
①Complete the command input from the air conditioning panel.
②The air conditioner panel sends the user's operation command to the controller through CAN communication or ON/OFF PWM.
③After the water heating PTC controller receives the command signal, it turns on the PTC in PWM mode according to the power requirement.
