hot selling portable hot air heater

PTC heater is also called PTC heating element, which is composed of PTC ceramic heating element and aluminum tube. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power saving electric heater. The outstanding feature is the safety performance. In any application situation, there will be no “redness” phenomenon on the surface of the electric heating tube heater, which will cause scalding, fire and other safety hazards. It consists of galvanized outer pressure plate, stainless steel corrugated spring sheet, galvanized inner pressure plate, single-layer aluminum heat sink, ptc heating plate, double-layer aluminum heat sink, nickel-plated copper electrode terminal and pps high temperature plastic electrode sheath. Due to the use of u-shaped corrugated heat sinks, this product improves its heat dissipation rate, and combines the advantages of adhesive and mechanical type, and fully considers various thermal and electrical phenomena of the ptc heating element during operation, and its bonding force is strong. , Excellent thermal conductivity and heat dissipation performance, high efficiency, safety and reliability. This type of PTC heater has the advantages of small thermal resistance and high heat exchange efficiency. It is an automatic constant temperature and power saving electric heater. One of its outstanding features is its safety performance, that is, when the fan fails and stops, the power of the PTC heater will automatically drop sharply due to insufficient heat dissipation. At this time, the surface temperature of the heater is maintained at about the Curie temperature ( Generally around 250°C), so as not to produce the phenomenon of “redness” on the surface of heaters such as electric heating tubes.

PTC ceramic heater based on heat conduction. It is characterized by the multi-layer heat transfer structure such as the electrode plate (electricity and heat transfer) insulating layer (electricity isolation and heat transfer) thermal heat storage plate (some are also attached with thermal conductive glue) installed on the surface of the PTC heating element. The emitted heat is transferred to the heated object. Various PTC ceramic heaters that conduct convection heat transfer with the formed hot air. It is characterized by large output power and can automatically adjust the air temperature and heat output. Infrared radiant heater. Its characteristics actually use the heat rapidly emitted from the surface of the PTC element or the heat-conducting plate to directly or indirectly excite the far-infrared paint or far-infrared material that contacts its surface to radiate infrared rays, which constitutes a PTC ceramic infrared radiation heater.
