It is the first high-power PTC heater (High-Voltage Coolant Heater-HVCH) in China, which breaks the bottleneck of High-Voltage Coolant Heater-HVCH in high voltage and high power technology, and can dry burn for more than 1000h.
The power of a single chip is about 110W/chip, which is 30% higher than that of the traditional process. It has low thermal resistance and good heat transfer. It solves the problem of PTC thermal breakdown. The maximum power of a single chip can be increased freely, such as 30KW or 40KW.
