The present invention relates to a ribbon heater for an auxiliary heating device.

In general, a vehicle is provided with an air conditioner for heating or cooling the room, and evenly transports cold and warm air to each part of the vehicle through the ventilation system and the ventilation passage. That is, in the air conditioner of the vehicle, the cold air generated in the evaporator of the air conditioner, or the warm air generated in the engine is transferred to the interior of the vehicle to cool or heat.

In the case of cooling to lower the indoor temperature, such as in summer, the air conditioner is operated to discharge cold air.In the case of heating to increase the temperature of the interior, such as winter, the cooling water heated by circulating the engine is blown through the blower to prevent the engine from overheating Heat exchange with the outside air supplied to the to supply the warmth through the discharge holes are arranged in various places in the vehicle.

Heat generated from the engine is generated as fuel is burned in the cylinder, and the temperature of the combustion gas generated at this time is about 2000 ° C to 2500 ° C, which damages components constituting the engine. The temperature of the engine is maintained at about 80 ° C to 90 ° C by the temperature, that is, the circulation of the cooling water.

Although it is preferable to efficiently heat the room by using the coolant heat exchanged with the engine, it is possible to heat the interior of the vehicle by using the heated coolant only after the time until the engine is heated after the initial start-up. For this reason, in winter, the engine is idling for a long time before driving in order to immediately heat the boarding, which causes inconvenience due to environmental pollution, fuel consumption and vehicle noise.

Therefore, an auxiliary heating apparatus is disclosed in which warm air is formed in an auxiliary heater made of a hot wire coil and blown to a room before the cooling water is heated. However, the auxiliary heater method using a heating coil has a problem that the heating effect of the heating coil is large, the heating effect is large, but the risk of fire is high, the life of the heating wire is short, and the parts of the heating coil must be frequently repaired and replaced.

Therefore, research on new devices that replace heating means such as heating coils as described above has been actively conducted, and has a constant resistance thermistor (PTC) having a constant resistance temperature coefficient that can be used semi-permanently due to a low risk of fire and a long life. Device: Positive Temperature Coefficient Thermister is widely known.

Auxiliary heating apparatus using a PTC element is disclosed in Korea Patent Nos. 10-0479187, 10-0474094, 10-0576371 and the like. The PTC device is a static thermistor having a constant resistance temperature coefficient made by mixing tin, cerium, and the like in a barium titanate-based semiconductor by about 0.1% as the temperature increases, and the resistance value varies with the ambient temperature. Therefore, it is an economical and efficient sensor-type heating element that generates high heat at low temperatures and low heat again at high temperatures. It has automatic temperature control and automatic protection from overheating and overvoltage. In addition, there is a characteristic that does not generate an oxidizing gas that causes air pollution because it does not react with oxygen in the air.

Since each conductive carbon mixture is bonded only to a part of the heat sink, the temperature distribution is uneven for each heat sink, and the temperature transmitted to each heat sink is different.The PTC element sinters and solidifies the PTC raw powder to form an electrode member. Since the manufacturing process and assembly process are complicated and each part is densely packed, the ventilation resistance increases during blowing, and the PTC element has the characteristic that the initial inrush current increases as the temperature rises. When used at high temperature, the inrush current is increased to exceed the capacity of the battery (100 ~ 120A), the car battery is discharged there was.

In order to solve this problem, an auxiliary heating device having a planar heating element is disclosed in Korean Laid-Open Patent No. 2006-0021428.
