Advantages and disadvantages of PTC electric vehicle heaters
First, PTC electric vehicle heater upwind:
1. Fast heating, aluminum sheet is denser. Higher thermal efficiency.
2. Health, environmental protection, no glue is healthier.
3. Super long, durable, non-oxidizing. Application life up to 6000 hours.
4. PTC electric vehicle heaters have a thermal efficiency of up to 99%.
Second, PTC electric vehicle heater disadvantages:
1. Not energy-saving.
2. Metal electric heating materials are easy to oxidize at high temperatures. Power attenuation. Short application life. Since its metal is flat, the contact area with the atmosphere is larger than that of wire. The application life is also short.
PTC Electric Vehicle Heaters Expand Data:
1. PTC electric vehicle heaters are divided by conduction mode
1. PTC ceramic heater based on heat conduction. It is characterized by the fact that the heat emitted by the PTC heating element is transferred to the heated object through a multi-layer heat transfer layout such as electrode plate (conductive and heat transfer), insulation layer (electrical insulation and heat transfer), thermal conductive and thermal storage plate (some of which are also equipped with thermal grease).
2. All kinds of PTC ceramic hot atmosphere heater. The exercise causes convective heat transfer in the hot atmosphere. It is characterized by high output power. The supply air temperature and output heat are automatically adjusted.
3. Infrared radiant heater. Its characteristic is that PTC ceramic infrared radiation heaters are caused by directly or indirectly causing far-infrared coatings or far-infrared materials that touch the appearance of PTC elements or thermal conductive plates to radiate infrared rays.
