Heat dissipation conditions and power selection of heaters

PTC ceramic heaters have low cost and long lifespan. Mastering the fever of a heater does not require additional temperature sensors such as temperature regulators and thermal resistance thermocouples. The temperature adjustment depends on the material characteristics of the heater itself, so the lifespan of the product far exceeds that of other heaters. This utility model has the advantages of low thermal resistance and superior heat exchange efficiency, and is an automatic constant temperature and energy-saving electric heating equipment.

A main feature is its full performance, which will not cause safety issues such as burns and fires due to the phenomenon of heating tubes and other heating surfaces turning red in any application. The prominent feature is that the PTC ceramic heater is completely environmentally friendly. The heating temperature of the radiator body is designed to be below 200 degrees Celsius, and the body will not turn red under any circumstances. It has a protective partition and does not require cooling of insulation materials such as asbestos. It can be used calmly and will not cause burns or fires to the human body.

The heat dissipation conditions of PTC heaters include the size of aluminum pipes and strips, the spacing between corrugated plates, The placement position of the PTC heater inside the air conditioner, and whether the air duct is reasonable, etc. The larger the size of aluminum pipes and strips, the better the heat dissipation conditions. It is appropriate to reduce the spacing between corrugated plates to increase the area of corrugated plates, and the heat dissipation conditions can be improved, The placement angle of the PTC heater in the air conditioner is more beneficial for the heat dissipation conditions of the airflow passing through the corrugated plate, and the air duct design of the air conditioner is also more beneficial for the circulation of airflow, which is more beneficial for the heat dissipation conditions of the PTC.

Other, The selection of PTC heater power is also a component that affects the heat dissipation condition. In order to improve the heating power of PTC heaters, the number of PTC components used has been increased, so that each component cannot fully utilize its heating power, resulting in an increase in the working temperature inside. Due to size limitations in the design of PTC electric heaters, 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.
