The prerequisite for heat dissipation of the heater includes the size of the aluminum tube and aluminum strip, as well as the spacing between the corrugated plates, The installation position of the PTC heater inside the air conditioner and whether the air duct is reasonable are other factors. The larger the size of aluminum pipes and strips, the better the heat dissipation premise. It is appropriate to reduce the spacing between corrugated plates to increase the area of corrugated plates, and the heat dissipation premise is improved, The installation angle of the PTC heater in the air conditioner is more conducive to the heat dissipation premise of the airflow passing through the corrugated plate, and the air duct plan of the air conditioner is also more conducive to the circulation of the airflow, which is more conducive to the heat dissipation premise of the PTC.
Other, The selection of PTC heater manufacturer's power is also a factor that affects the heat dissipation status. In order to improve the heating power of PTC heaters, the number of PTC components used has been increased, making it impossible for each component to fully utilize its heating power and causing the working temperature inside to rise. Due to size limitations in the PTC electric heater plan, the heat dissipation area was determined. As the number of PTC heating elements increased, the balanced heat dissipation area of unit PTC elements decreased, resulting in an increase in the thermal density of PTC ceramic sheets.
The function and parameters of PTC electric heater fuse. Rated voltage refers to the large voltage that the fuse can withstand after being disconnected. There are many types of fuses, and commonly used fuses can be divided into three categories: glass tube fuses, ceramic tube fuses, and polymer self recovery fuses. Usually, when selecting a fuse, the temperature regulation of the high-temperature fan's rated voltage depends on its own material characteristics, making the product much larger than other products. The demand is greater than the effective circuit voltage. The rated current is a fuse that can operate for a long time. High current. Assuming the protection current is Ir, the rated current of the fuse should be selected as the low drop rate of different specifications of fuses. The higher the temperature of the situation, the higher the temperature during the operation of the fuse, and the shorter the service life. What should be exaggerated here is that the air temperature around the fuse should not be mixed with the temperature of the room. PTC ceramic heaters save costs and have a long service life. Temperature feedback does not require an external temperature controller, thermocouple, or other temperature sensors to control the heating of the heater.
