Description

Auxiliary heating device for automobiles

This invention is installed on the air movement path of the automobile air conditioning equipment, and the heat emission from the device is uniform by using PTC element which generates electricity at the same time as the power is supplied to heat the air supplied to the interior of the car at the same time as the power supply. The present invention relates to an auxiliary heating device for a vehicle which is easy to assemble and withstands external forces such as vibration, bending, or torsion.

Generally, an air conditioner for heating or cooling an interior of a vehicle is installed to evenly transport cold and warm air to each part of the vehicle through a ventilation system and a ventilation path.

1 is a schematic configuration diagram of an air conditioner of a conventional vehicle.

As shown, the cold air generated in the evaporator of the air conditioner, or the warmth generated in the engine is transferred in the direction of the arrow to cool or heat the respective interior parts of the vehicle.

In other words, in the case of cooling to lower the indoor temperature in summer, the air conditioner is operated to discharge cold air. In the case of heating to increase the indoor temperature in winter, the coolant heated by circulating the inside of the engine is cooled to prevent the engine from overheating. Heat exchange with the outside air supplied into the room through the outlet to be supplied throughout the vehicle to supply the warmth.

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 approximately 80 ° C to 90 ° C by the circulation of the temperature, that is, 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 to heat immediately upon boarding, which causes inconvenience due to environmental pollution, fuel consumption, and vehicle noise.

Therefore, as a proposed solution, an auxiliary heater system is proposed in which warm air is formed in an auxiliary heater made of a hot wire coil and blown into the room until the cooling water is heated. However, the auxiliary heater method using the 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 or replaced.

On the other hand, the recent research on new devices that replace the heating means such as heating coils, such as the above, a constant resistance temperature coefficient that can be used semi-permanently due to the low risk of fire, long life Positive temperature coefficient thermistors (PTCs) are commonly known as 'PTC devices'.

Accordingly, an object of the present invention is to provide a vehicle auxiliary heating device using a PTC element that exhibits a low heat risk, excellent durability, and a predetermined heat generation performance at the same time as supplying power from an auxiliary heater system of a hot wire coil type. It is to provide auxiliary heating device.

In addition, the PTC element and the insulator are equally divided so as to be alternately arranged on the front and rear surfaces of the first electrode member to provide an auxiliary heating device for automobiles having a uniform heat generation performance.

In addition, the purpose is to provide an auxiliary heating device for automobiles with excellent durability to withstand the vibration of the vehicle by having a vertical fixed shaft and a horizontal fixed plate body fixed to each other.
