Ceramic heater is forced convection heating equipment an important issue is how to design

PTC ceramic heater is a short name for ceramic heating elements. It uses the fan to encourage air flow through the PTC heating element forced convection, as the main heat exchange. Its internal temperature limiter, when the outlet is blocked by the fan, can be self-power. And some also equipped with dumping switch, when the heater can dump their own power off.

PTC ceramic heater  is a short name for ceramic heating elements. It uses the fan to encourage air flow through the PTC heating element forced convection, as the main heat exchange. Its internal temperature limiter, when the outlet is blocked by the fan, can be self-power. And some also equipped with dumping switch, when the heater can dump their own power off.

Its output power in the 800-1200 watts, free to adjust the temperature, the work of soft air supply, heating up fast, with automatic temperature function, PTC components are generally waterproof, so suitable for use in the bathroom, priced at 300 to 500 yuan , Is the ideal portable home heater.

(1) heat conduction-based PTC ceramic heater, which is characterized by the PTC heating element surface mounted electrode plate (conductive and heat transfer) insulation layer (insulation and heat transfer) thermal insulation board (some also attached Thermal plastic) and other multi-layer heat transfer structure, the PTC component of the heat generated by the heated object.

(2) A variety of PTC ceramic heaters for convective heat transfer in the form of hot air, which are characterized by large output power and automatic regulation of blown air temperature and output heat.

(3) infrared radiation heater. Its characteristics The actual use of PTC components or thermal conductivity of the surface of the heat generated directly or indirectly to stimulate the surface of the far infrared paint or far infrared materials to radiate the infrared, it constitutes a PTC ceramic infrared Radiation Heater.

(1) ordinary practical PTC ceramic heater. Such appliances are: electric mosquito mosquito repellent, warm hand, dryer, electric panels, electric iron, electric iron, electric adhesives, hair curlers and so on. It is characterized by little power, but the thermal efficiency is very practical.

(2) automatic thermostatic PTC heater. Such appliances are: small crystal device thermostat, incubator, electronic thermos, incubator, insulation Cup, insulation board, insulation cabinet, insulation tables. It is characterized by automatic insulation, simple structure, good temperature characteristics, high thermal efficiency, the use of a wide range of ambient temperature range.

(3) hot air PTC heaters. These hot air PTC heaters are: small warm air heater, hair dryer, warm room machine, dryer, dry wardrobe, dryers, industrial drying equipment, etc. It is characterized by output Hot air power, fast heat, safe, can automatically adjust the wind temperature and power consumption.

Ceramic heater is forced convection heating equipment, an important issue is how to design the heat generated by PTC in a timely manner, depending on the design of the fan and duct. The wind source used has axial fan, cold fan fan, drum fan, centrifugal fan and so on. The basic requirement is that the wind speed acting on the windward surface of the PTC heater is uniform, otherwise the efficiency of the heater will be greatly affected, and the PTC element can not fully develop its own capacity. The wind speed should be reasonable, the power consumption of the PTC heater The export wind temperature is closely related to the wind speed, the wind speed increases, the power increases, the wind temperature decreases. In addition there should be with the good duct design.
