PTC ceramic heater has low cost and long life. There is no need for temperature sensors such as special temperature regulators and thermal resistance thermocouples to control the heater fever. The temperature adjustment depends on the material characteristics of the heater itself, so the life of the product is far longer than other heaters. The applicable model has the advantages of low thermal resistance and superior heat exchange. It is an electric heating equipment with automatic constant temperature and power saving.
One of the main features is that it has full performance. In any application, the heater surface such as the electric heating tube will not "turn red", causing safety problems such as burns and fire. The outstanding feature is that the PTC ceramic heater is completely environmentally friendly. The heating temperature of the main body of the radiator is designed to be below 200 degrees, and the main body will not turn red under any circumstances. It has protective partitions and does not need to cool asbestos and other heat insulating materials. It can be used calmly and will not cause burns or fire to the human body.
The heat dissipation conditions of the PTC heater include the size of the aluminum tube and the aluminum strip, the size of the corrugated sheet spacing, the placement of the PTC heater in the air conditioner, and whether the air duct is reasonable or not. The larger the size of aluminum pipes and aluminum bars, the better the heat dissipation conditions. It is appropriate to reduce the distance between the corrugated plates to increase the area of the corrugated plates, and the heat dissipation conditions are improved. The angle of the PTC heater in the air conditioner is more conducive to the heat dissipation of the airflow through the corrugated plates. Conditions, the air duct design of the air conditioner is more beneficial to the circulation of airflow, the more beneficial the heat dissipation conditions of the PTC.
In addition, the selection of the power of the PTC heater is also a component that affects the heat dissipation condition. In order to increase the fever power of the PTC heater, the number of PTC components applied is increased, so that each component cannot fully develop its fever power, and the working temperature inside is raised. . Because the size limitation and heat dissipation area are determined during the design of the ptc electric heater, as the number of PTC heating elements increases, the balanced heat dissipation area of the unit PTC element decreases, thereby increasing the heat density of the PTC ceramic sheet.
The performance and parameters of the fuse of the PTC heater manufacturer. Rated voltage Rated voltage refers to the large voltage that can be withstood after the fuse is disconnected. The voltage at both ends of the fuse is far less than its rated voltage during the on-time Self-recoverable fuses (made of PPTC plastic polymer) are of three types. Usually, when the fuse is selected, the temperature adjustment of the rated voltage of the high-temperature fan depends on its own material characteristics, so the product is much larger than other products. The demand is greater than the useful circuit voltage. Rated current Rated current is a fuse that can work for a long time. High Current. Assuming that the guard current is Ir, the rated current of the fuse should be selected as the reduction rate of the fuse of different specifications. The higher the ambient temperature, the higher the temperature of the fuse during operation, and the shorter the application life. The car PTC heater should be exaggerated here is that the air temperature around the fuse should not be confused with the relative temperature and temperature of the room. PTC ceramic heaters are diligent and frugal, and have a long application life. The temperature response does not require an extra temperature controller, thermal resistance thermocouple and other temperature sensors to control the heating of the heater.
