As the surface temperature of the PTC electric heater increases, the power increases. Please note the application of PTC electric heater electric furnace. PTC heaters have automatic thermostat results. No temperature control system required. Blister and crisp start the power supply. Heating liquids (such as water) are held with a positive temperature coefficient heating sheet, and the positive temperature coefficient heating sheet will not be destroyed after drying. If a positive temperature coefficient heater is accepted to heat the cold atmosphere, the positive temperature coefficient heater of the high temperature fan will not be destroyed in a non-supplied environment. It has a long application life, which can exceed 10 years in a flat living environment. Work reliably, using PTC heater internal temperature control to complete overtemperature. Unstable operating voltage width: Changes in twice the operating voltage have little effect on the surface temperature. If there are multiple PTC electric heater heating plates applied at the same time, the parallel connection method should be accepted instead of the series connection. The difference in heat dissipation rate makes the heating power of PTC heaters vary greatly. After turning on, the heating power is stable from high to low. Power stability is related to application conditions, the same PTC electric heater heater, the application conditions are different, the power can be several times different. The electric heater has fast thermal response, accurate temperature control, and high comprehensive thermal obedience.
PTC ceramic heaters save costs and have a long application life. Its obvious feature is that PTC ceramic heaters are safe, low-carbon and environmentally friendly. The decision of the electric heater itself is that the heating temperature is below 2000 degrees Celsius. In all environments, the body does not redden, and there is a protective layer. All application places should not use rock wool, glass magnesium and other thermal insulation raw materials to hold cooling solutions, can be safely applied, can not find the problem of burns and fire accidents. Without the need for a professional temperature controller, thermal resistance, platinum thermal resistance and other humidity sensors to hold a temperature response, you can control the scald of the electric heater. Its temperature conditioning depends on the characteristics of its raw materials, making the application life of the product much higher than that of other electric heaters. This PTC electric heater has the characteristics of small heat transfer coefficient, and is a fully automatic temperature control and energy-saving electric heater. One of its bulge characteristics depends on the safety factor. Under all application conditions, it is not easy to cause redness on the surface of the heating tube electric heater, resulting in burns, fire accidents and other safety hazards.
The heat dissipation conditions of PTC electric heaters include aluminum tubes, aluminum strip size, corrugated sheet spacing, PTC heater placement position in air conditioning, whether the air duct is reasonable and other components. The larger the size of the aluminum tube and aluminum strip, the better the heat dissipation conditions, appropriately reduce the corrugated plate spacing, increase the corrugated plate area, improve the heat dissipation conditions, the more beneficial the air conditioning placement angle is to the heat dissipation conditions through the corrugated plate, the more beneficial the air conditioning duct decision is to the airflow circulation, and the more beneficial it is to the heat dissipation conditions of PTC.
In addition, the choice of PTC heater power is also a joint component that affects heat dissipation. In order to improve the heating power of the PTC heater, increase the number of PTC components applied, so that each component can not give full play to its heating power, and improve the internal operating temperature. Since the size range and heat dissipation area of PTC electric heaters are determined in the decision, as the number of PTC heating elements increases, the average heat dissipation area of PTC elements decreases, and the thermal density of PTC ceramic sheets increases.
