What should be paid attention to when the surface temperature of the PTC heater increases- Ningbo Sungroy Electric Appliances Tech.Co.,Ltd.

As the surface temperature of the PTC electric heater increases, the power increases. Please pay attention to the application of PTC electric heater electric furnace. The PTC heater has an automatic constant temperature effect. There is no temperature control system. Attractive brittle starter power. Use a PTC heater to heat liquids (such as water), and the PTC heater will not be damaged after drying. The PTC heater of the high temperature fan will not be damaged in a non-air supply environment if it accepts a PTC heater to heat the cold air.

Long service life, can be used for more than 10 years in the living environment. Reliable work, using PTC heater internal temperature control to complete over-temperature. The working voltage width is not stable: the change of twice the working voltage has little effect on the surface temperature. If multiple PTC electric heater heating plates are used at the same time, parallel connection should be accepted instead of series connection. The difference in heat dissipation rate makes a big change in the heating power of the PTC heater. After starting, the heating power is stable from high to low. The power control is the same as the PTC heating conditions with the same application conditions.

PTC ceramic heaters save cost and have a long service life. Its obvious feature is that the PTC ceramic heater is safe, low-carbon and environmentally friendly. The heating temperature of the electric heater itself is lower than 2000 degrees Celsius. Under all circumstances, the body is not red and has a protective coating. Insulation materials such as rock wool and glass magnesium are not used for cooling solutions in all applications, and can be used safely without burns and fire accidents. There is no need for professional temperature controllers, thermal resistance, platinum thermal resistance and other humidity sensors to perform temperature response, and the electric heater can be scalded. Its temperature regulation depends on the characteristics of its raw materials, so that the service life of the commodity is much higher than that of other electric heaters. PTC electric heater has the characteristics of small heat transfer coefficient, and is an electric heater with automatic temperature control and energy saving. One of its outstanding features depends on the safety factor. Under all application conditions, it is not easy to cause safety hazards such as redness on the surface of the heating tube electric heater and fire accidents.

The heat dissipation conditions of the PTC electric heater include the aluminum tube, the size of the aluminum strip, the spacing of the corrugated sheets, the position of the PTC heater in the air conditioner, and whether the air duct is reasonable. The larger the size of the aluminum tube and aluminum strip, the better the heat dissipation conditions. The spacing of the corrugated plates is appropriately reduced, the area of the corrugated plates is increased, and the heat dissipation conditions are improved. The circulation is also more conducive to the heat dissipation conditions of the PTC.

In addition, the choice of PTC electric heater power is also a joint component that affects heat dissipation. In order to improve the heating power of the PTC heater, the number of applied PTC elements is increased, so that each element cannot fully exert its heating power, and the internal working temperature is increased. Since the size range and heat dissipation area of the PTC electric heater are determined in the decision, with the increase of the number of PTC heating elements, the average heat dissipation area of the PTC element decreases, and the heat density of the PTC ceramic sheet increases.
