PTC heaters are divided into nbsp according to conduction mode; (1) PTC ceramic heaters based on heat conduction. It is characterized by multi-layer heat transfer structures such as electrode plate (conductive and heat transfer), insulation layer (power insulation and heat transfer), thermal conductive heat storage plate (some with thermal conductive glue) installed on the surface of the PTC heating element, etc., the heat emitted by the PTC element is transferred to the heated object.nbsp;(2) Various PTC ceramic hot air heaters for convective heat transfer with the formed hot air. It is characterized by large output power, and can automatically adjust the blowing air temperature and output heat.nbsp;(3) infrared radiation heater. Its characteristics: actually using the rapid heat emitted on the surface of PTC elements or thermal conductive plates to directly or indirectly stimulate the far-infrared coating or far-infrared material that contacts its surface to radiate infrared rays, which constitutes a PTC ceramic infrared radiation heater.nbsp; PTC heaters are divided into nbsp according to structural characteristics;(1) ordinary practical PTC ceramic heaters. The main appliances of this kind are: NBSP; Electric mosquito repellent, hand warmer, dryer, electric hot plate, electric iron, electric soldering iron, electric adhesive, curly hair perm, etc. It is characterized by small power, but high thermal efficiency and practical .nbsp;(2) automatic constant temperature type PTC heater. Such appliances mainly include: small crystal device thermostatic tank, constant temperature incubator, electronic thermos flask, NBSP; Incubator, thermos cup, insulation tray, insulation cabinet, insulation table, etc. It is characterized by automatic heat preservation, simple structure, NBSP; Good constant temperature characteristics, high thermal efficiency, wide ambient temperature range.nbsp;(3) Hot air PTC heater. This type of hot air PTC heater mainly includes: small warm air heater, hair dryer, house warmer, dryer, dry wardrobe, dryer, industrial drying equipment, etc.nbsp; It is characterized by large output hot air power, fast heating, safety, and can automatically adjust the air temperature and power consumption. Question 2: PTC heaters do not consume oxygen. Question 3: NBSP; It will dry the air in the bedroom, and it is best to buy a humidifier.
