The main purpose of automobile PTC heater
As a new type of thermistor material, automobile PTC heaters are mainly used for switching and heating. The use of PTC material has the switching characteristics of heat sensitivity, current limiting, time delay, etc. and the characteristics of non-contact, noise-free application and long life. It can be applied to refrigerator startup, motor transformer protection, program control switch protection, mosquito repellent, curling hair perm , Electric irons and other small household appliances. Utilizing the characteristics of stable function of heating PTC, rapid heating up, and little influence by power supply voltage fluctuations, various heater products made have become ideal substitutes for metal resistance wire heating materials. At present, it has been widely used in heaters, clothes dryers, air curtains, air conditioners, etc.
The automobile PTC heater adopts the PTCR thermal ceramic element, which is composed of a geometric monolithic combination and a corrugated heat-dissipating aluminum strip through high-temperature adhesive layout, which has a prominent effect of low thermal resistance and high heat exchange compliance. Its great feature lies in its safety, that is, when the fan fails and the rotor is blocked, the PTC heater will not get sufficient heat dissipation, and the power will automatically drop sharply. At this time, the surface temperature of the heater is limited to the Curie temperature (normal 220°C), so as not to cause "redness" on the surface of the electric heating tube heater, and eliminate the hidden danger of accidents.
PTC heater is an internationally popular, high-quality, long-life electric heating equipment. It is generally used to heat up, keep warm, and heat up liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, it receives the huge heat generated in the work of the leakage electric heating element with the fluid thermodynamics symmetrically, so that the temperature of the heated medium reaches the user's process requirements.
PTC heater is the process of converting electrical energy into heat energy. Since it was discovered that the power supply can have a heating effect through wires, many discoverers in the world have been engaged in the research and production of various electric heating appliances. The development and popularization of electric heating are also the same as other industries. It follows a rule: from advanced countries to countries around the world; from cities to rural areas; from collective applications to households, and then to one-sided; products from low-end development to Upscale.
