Language The heat dissipation conditions of the PTC fan heater include the aluminum tube, the size of the aluminum strip, the spacing of the corrugated sheets, the installation position of the PTC heater in the air conditioner, and the wind. For the machine head of the aluminum tube, the larger the size of the aluminum strip, the better the heat dissipation. The distance between the corrugated plates is appropriately reduced, the area of the corrugated plate is increased, and the heat dissipation conditions are improved. The installation angle of the air conditioner is more conducive to the heat dissipation conditions through the corrugated plate. The more favorable the air circulation is, the more favorable the PTC heat dissipation conditions are.
In addition, the selection of PTC electric heater power has an important influence on heat dissipation. In order to improve the heating power of the PTC heater, increase the usage of PTC components, so that it cannot fully exert its own heating power and increase the internal working temperature.
The size range and heat dissipation area of the PTC electric heater are designed and analyzed. With the increase of the number of PTC heating elements, the average heat dissipation of the device decreases, and the thermal density of the ceramic sheet also increases.
