New-energy automobile high speed development in recent years, PTC is because there is the security attribute of automatic constant-temperature, it has also become new-energy automobile
The mainstream of air-conditioning heating.But ptc heater used in new-energy automotive air-conditioning substantially continues to use domestic air conditioning ptc heater at present
Structure, since running car has various vibrations, and PTC used does not consider anti-seismic performance currently on the market, in structure
There are the risks that plastic seating rupture, radiator fall off.
Traditional ptc heater has the disadvantage that:
1, radiator and aluminum pipe are adhesive structure
Traditional ptc heater radiator and aluminum pipe are adhesive structure, and bonded adhesives use for a long time will appear aging, and bonding is strong
Degree is substantially decayed, and there are the security risks that radiator falls off.
2, using plastic cement support base
The plastic cement support base that traditional ptc heater uses is due to requiring high temperature resistant, and material is more crisp, elasticity is small, and vibration is held
Easily cause embrittlement.
3, aluminum pipe thickness is too thin
Traditional ptc heater aluminum pipe thickness is generally 0.9mm, easily deforms under shockproofness.
